tft lcd vs led pricelist

According to TrendForce, LCD TV panel quotations bore the brunt of continuous downgrades in the purchase volume of TV brands and pricing for most panel sizes have fallen to record lows. Recently, it was announced that the 32-inch and 43-inch panels fell by approximately US$5~US$6 in early June, 55-inch panels fell approximately US$7, and 65-inch and 75-inch panels are also facing overcapacity pressure, down US$12 to US$14. In order to alleviate pressure caused by price decline and inventory, panel makers are successively planning to initiate more significant production control in 3Q22. According to TrendForce’s latest research, overall LCD TV panel production capacity in 3Q22 will be reduced by 12% compared with original planning.

As Chinese panel makers account for nearly 66% of TV panel shipments, BOE, CSOT, and HKC are industry leaders. When there is an imbalance in supply and demand, a focus on strategic direction is prioritized.  According to TrendForce, TV panel production capacity of the three aforementioned companies in 3Q22 is expected to decrease by 15.8% compared with their original planning, and 2% compared with 2Q22. Taiwanese manufacturers account for nearly 20% of TV panel shipments so, under pressure from falling prices, allocation of production capacity is subject to dynamic adjustment. On the other hand, Korean factories have gradually shifted their focus to high-end products such as OLED, QDOLED, and QLED, and are backed by their own brands. However, in the face of continuing price drops, they too must maintain operations amenable to flexible production capacity adjustments.

TrendForce indicates, in order to reflect real demand, Chinese panel makers have successively reduced production capacity. However, facing a situation in which terminal demand has not improved, it may be difficult to reverse the decline of panel pricing in June. However, as TV sizes below 55 inches (inclusive) have fallen below their cash cost in May (which is seen as the last line of defense for panel makers) and is even flirting with the cost of materials, coupled with production capacity reduction from panel makers, the price of TV panels has a chance to bottom out at the end of June and be flat in July. However, demand for large sizes above 65 inches (inclusive) originates primarily from Korean brands. Due to weak terminal demand, TV brands revising their shipment targets for this year downward, and purchase volume in 3Q22 being significantly cut down, it is difficult to see a bottom for large-size panel pricing. TrendForce expects that, optimistically, this price decline may begin to dissipate month by month starting in June but supply has yet to reach equilibrium, so the price of large sizes above 65 inches (inclusive) will continue to decline in 3Q22.

TrendForce states, as panel makers plan to reduce production significantly, the price of TV panels below 55 inches (inclusive) is expected to remain flat in 3Q22. However, panel manufacturers cutting production in the traditional peak season also means that a disappointing 2H22 peak season is a foregone conclusion and it will not be easy for panel prices to reverse. However, it cannot be ruled out, as operating pressure grows, the number and scale of manufacturers participating in production reduction will expand further and it timeframe extended, enacting more effective suppression on the supply side, so as to accumulate greater momentum for a rebound in TV panel quotations.

Thanks for the display technology development, we have a lot of display choices for our smartphones, media players, TVs, laptops, tablets, digital cameras, and other such gadgets. The most display technologies we hear are LCD, TFT, OLED, LED, QLED, QNED, MicroLED, Mini LED etc. The following, we will focus on two of the most popular display technologies in the market: TFT Displays and Super AMOLED Displays.

TFT means Thin-Film Transistor. TFT is the variant of Liquid Crystal Displays (LCDs). There are several types of TFT displays: TN (Twisted Nematic) based TFT display, IPS (In-Plane Switching) displays. As the former can’t compete with Super AMOLED in display quality, we will mainly focus on using IPS TFT displays.

OLED means Organic Light-Emitting Diode. There are also several types of OLED, PMOLED (Passive Matrix Organic Light-Emitting Diode) and AMOLED (Active Matrix Organic Light-Emitting Diode). It is the same reason that PMOLED can’t compete with IPS TFT displays. We pick the best in OLED displays: Super AMOLED to compete with the LCD best: IPS TFT Display.

Reports suggest that Apple is getting closer to implementing MicroLED in its future product releases, including the Apple Watch, with the display technology potentially offering a number of benefits compared to other methods. AppleInsider explains how the current TFT and OLED display technologies work, and how MicroLED differs.

MicroLED shows promise as a display technology, potentially offering power savings and a reduced screen thickness when put beside current-generation display panels. Apple has recognized the potential, and has invested heavily into developing the technology over the last few years, with a view to using it in the company"s future products.

To understand fully how MicroLED can benefit Apple, it is worth understanding how the commonly-used display technologies work in the first place, before examining how different MicroLED really is in a comparison.

The most common display technology used by consumer products today, and the oldest of the technologies examined in this article, TFT"s full name of TFT LCD stands for Thin-film-transistor liquid-crystal display. This technology is extensively used by Apple in its products, found in iPads, iPhones, MacBooks, and iMac lines.

The LCD part relates to the concept of defining small translucent or transparent areas in a thin and flexible liquid crystal-filled panel, like the displays used in calculators. Passing current through the segment changes the molecular properties of the defined segment area, allowing it to switch between being see-through or opaque.

TFT takes this a stage further, by effectively covering an entire panel with a grid of isolated liquid crystal segments, which again can vary between opaque and transparent based on the level of electrical current. In this case, there are far more segments needed to make up the display than with a normal calculator.

Polarizing filters on either side of the TFT display sandwich are used to prevent light from passing through directly, with the liquid crystal reaction of each segment affecting polarized light passing through the first filter to go through the second.

Sometimes these types of display are known as "LED," but this somewhat of a misnomer, as this actually refers to the use of Light Emitting Diodes as a light source. The LED backlight shines light through the various layers making up the TFT LCD.

Displays that use collections of LEDs as individual pixels do exist, but it isn"t usually found in consumer products. LED screens are commonly used for billboards, in attractions, and as a large-scale display for events.

TFT LCD screens continue to be widely used in production for a number of reasons. Manufacturers have spent a long time perfecting the production of the display panels to make it as cheap as possible, while its high usage allows it to benefit from economies of scale.

Used in consumer devices in a similar way to TFT LCD, OLED (Organic Light-Emitting Diode) is a display technology that is similar in the basic concept, but differs considerably in its execution. Again, the idea is for a thin panel to be divided up into segments, with charge applied to each section to alter its molecular properties, but that"s where the techniques diverge.

As the name implies, OLED uses an organic compound film that is put between two electrodes, which are used to provide charge. Instead of the charge changing how light passes through, the current instead causes the emissive electroluminescent layer to emit light, without the need for a rear light source.

These self-emitting pixels gives OLED a considerable advantage over LCD-based systems in a number of areas. Most obviously, by not needing a backlight, OLED panels can be made far thinner than an equivalent LCD-based display, allowing for the production of thinner devices or more internal area for other components, like a larger battery.

The power efficiency of OLED panels can be far greater, as while a TFT screen requires an always-on backlight, the brightness of OLED pixels themselves determine power usage, with a black pixel consuming no power at all. OLED screens are also faster to respond than LCD displays, making them more useful for VR displays, where response time needs to be as rapid as possible.

This also allows OLED to provide superior contrast ratios compared to TFT, as the lack of backlight bleed-through that occurs in TFT simply doesn"t happen in OLED.

OLED also can be produced on plastic substrates instead of glass, allowing it to be used to create flexible displays. While this is currently embodied in curved and other non-flat screens in some devices, it has the potential to be employed in foldable smartphones or rolled up for storage, an area Apple is also allegedly examining.

Despite the advantages, OLED is still lagging behind TFT in terms of adoption. The cost of production is far higher, in part due to the need for extremely clean environments, as a single speck of dust can potentially ruining a display during fabrication.

OLED panels are also affected by the presence of water, both in production and in use. Small amounts of water contacting the organic substrate can cause immediate damage to the display, rendering parts of the screen useless.

So far, Apple"s usage of OLED consists of the premium iPhone X and the Apple Watch. As the cost of production drops down, it is plausible for Apple to use OLED in more future products, providing a better screen for customers to use.

Thought to be the next big thing in display technology, MicroLED basically takes the idea of using LEDs for pixels in a large stadium-style screen and miniaturizes it all.

Using extremely small LEDs, three MicroLEDs are put together to create each pixel, with each subpixel emitting a different color from the usual red, blue, and green selection. As each LED emits light, there is no need for a backlight as used in TFT screens.

MicroLED doesn"t use an organic compound to produce light, making it less susceptible to failure compared to OLED. Just like OLED, it can be applied onto a flexible material, allowing it to be used for curved displays or non-stationary components, like a watch strap, and can result in an extremely thin display panel.

MicroLED offers the same lower power consumption and high contrast ratio benefits as OLED when compared to TFT. However, MicroLED is also capable of producing a far brighter image than OLED, up to 30 times brighter, and is in theory more efficient in converting electricity into light.

As a relatively new and in-development technology, the cost of MicroLED production is extremely high in comparison to the more established OLED and TFT mass production lines, in part due to lower than required yields. Manufacturing equipment vendors have produced hardware for MicroLED production that cuts defects in half and reduces deposition deviance from 3 nanometers down to 1 nanometer, but it is unclear if this is enough to help mass production move forward.

While MicroLED is an attractive proposition for Apple, it is not the only technology under development by the company"s engineers. Apple has previously filed patent applications for a technology described as "Quantum Dot LED and OLED Integration for High Efficiency Displays."

Quantum Dots are photoluminescent particles included in an LED-backed TFT display that can produce brighter and more vibrant colors, with the colors produced depending on their size. While available in current QLED televisions, the technology is only really being used to enhance the backlight, rather than being used to illuminate individual pixels.

The technology in theory can create an even thinner display than OLED, along with a more streamlined manufacturing process. True QD displays are also capable of high pixel densities of up to 1,000ppi, multiple times the density required to be called a Retina-quality display, and based on Apple"s hybrid invention, will also boast the response times of OLED technology.

As is usually the case, Apple does produce a considerable number of patent applications every week that are filed with the US Patent and Trademark Office, and not everything it files will be fully commercialized.

Apple has been interested in using the technology for some time now, with the first notable sign being its acquisition of LuxVue in May 2014, alongside assorted related patents. A MicroLED specialist, LuxVue was rumored to have been the display producer for the ill-fated Google Glass headset, but was also the holder of assorted patents in the LED display field, including MicroLED.

At the time, the acquisition was thought to be an attempt by Apple to bring part of its display technology development in-house, with suggestions the MicroLED technology would be used in another rumored-at-the-time device, the Apple Watch. A more recent report suggests Apple is working with TSMC to make small panels for a future premium Apple Watch, potentially starting mass production by the end of the year.

Apple has also reportedly set up a secret facility just 15 minutes away from Apple Park, believed to be used for developing MicroLED. The 62,000 square-foot facility is thought to house around 300 engineers on a project named "T159," relating directly to the technology"s development.

The facility is also claimed to be sufficient in size to perform small scale manufacturing of display panels, allowing the company to keep development and testing in-house without involving third-parties. Considering Apple"s previous history in developing technologies before issuing information to manufacturing partners, it is possible that Apple is trying to work out the kinks in production before suppliers even attempt to make MicroLED panels.

Reports from last year also suggest Apple"s investment in MicroLED was a cause for concern for Samsung, LG, and other South Korean suppliers who provide display panels for the company"s products. Owning the process for MicroLED manufacturing could allow Apple to migrate away from its existing display suppliers in the coming years, reducing revenues and profits.

Aside from Apple"s development, there has been little in the way of announcements from other firms for products using the technology that could be bought by consumers in the coming months. The exception is Samsung, Apple"s main rival in the mobile marketplace and a major supplier of display panels, but its usage of MicroLED is not aimed at producing smaller screens.

At CES 2018, Samsung introduced The Wall, a 148-inch TV claimed to be the "world"s first consumer modular MicroLED" television. According to the South Korean electronics giant, The Wall"s modularity meant consumers would be able to customize their television"s size and shape to suit their needs.

The impending use of the technology in a high-priced consumer product could be considered proof that MicroLED display technology is maturing enough for use in devices. If the reports claiming Apple is getting close to mass producing panels is true, the inclusion of MicroLED in the Apple Watch could end up being the first mainstream usage of the technology.

As you can see, TVs from LG, Samsung, and Sony earned top scores in our testing across just about every size range. And generally, sets from these companies cost more than their competitors’ TVs.

Prices and average brand scores tend to drop off in step with each other, according to our analysis. One major change this year is that some secondary brands, including Element, Philips, and Westinghouse, no longer appearin our list. Sharp is no longer in our listing; it stopped selling TVs in the U.S. for several years but began selling them again in 2022. RCA is represented in just two screen sizes, where it has the lowest Overall Score, and in one instance the lowest price by a large margin.

In their place, we now have more models from up-and-coming brands such as Hisense and TCL, as well as from a few retailer-specific brands such as Insignia (Best Buy’s house brand) and Toshiba (sold through Amazon and Best Buy). TVs from these brands have been gaining market share at the expense of other lesser-known brands that were once regularly included in our analysis.

Although we’ve tested a few TVs from Onn, Walmart’s house brand, we didn’t test enough sets in any one screen size for it to appear. We hope to include it in next year’s evaluation.

Major brands dominate the top of this slice of our TV ratings, which include 70-, 75-, 77-, 82-, and 85-inch TVs. That list now includes TCL, which has become one of the three top-selling brands in the U.S.

The average price figures we show are a bit higher than the average for all big TVs on the market. That’s both because the largest sets carry a premium and because CR tends to purchase a lot of expensive, high-end sets. That allows us to test the latest features, such as Mini LED backlights in LCD/LED TVs, which can help boost contrast and reduce halos, and high dynamic range (HDR), which can produce brighter, more vibrant images.

We test these flagship models from all the brands, but with major brands there is a much greater difference in pricing between the least and most expensive sets they offer. For example, for TCL there’s a $600 difference between the cheapest ($700) and priciest ($1,300) 75-inch TVs in our current ratings. With Samsung, that difference is dramatic: $1,900. (See the best big-screen TV bargains for sets 70 inches and larger.)

You’ll see that Sony, Samsung, and LG top the list in terms of average Overall Score and average price. Given their high average scores, sets from any of these TV brands might be worth considering. Sony TVs tend to be expensive in part because the company, like LG, now offers OLED TVs, which tend to cost more, but also because it exited the budget TV market. The takeaway for shoppers is that a premium set from Sony might not be more expensive than a premium set from a competitor—the company just doesn’t compete in lower performance tiers.

TCL, Vizio, and Hisense are additional brands to consider, especially if you’re on a budget. With TCL and Hisense, higher-end sets (the 6- and 8-series TVs from TCL, and 8-series sets from Hisense) have done very well in our tests, offering a lot of bang for the buck in terms of both picture quality and high dynamic range (HDR) experience. TCL’s higher average price is due to its top-tier sets having newer technologies (Mini LED, 8K resolution), plus a push into very large screen sizes. The company also offers many low-priced sets that haven’t done as well, lowering the brand’s Overall Score. Vizio sets have done well for overall picture quality across the board, though they generally fall behind a bit when it comes to HDR.

This has become a popular screen size for people looking for a large TV. And you’ll see that LG, Samsung, and Sony top the list in average Overall Score and average price here, as well. One reason for the fine showing by both LG and Sony is they offer OLED TVs that have consistently been at the top of our ratings. Samsung’s top QLED (and Neo QLED) TVs have also done very well in our ratings, and the best of those sets now rival OLED TVs in performance. All these sets tend to be pricy.

In this size category, we again see much greater differences in pricing between the least and most expensive sets from major brands than from smaller players. For example, there’s a $600 difference between the cheapest ($400) and priciest ($1,000) 65-inch Hisense TVs in our current ratings. With Samsung and Sony, that difference is a whopping $2,400. One reason for Samsung’s large spread is the debut of itsfirst QD OLED TV ($3,000), which is now in our ratings (though it arrived too late this year for our statistical analysis). Sony TVs tend to be expensive in part because the company offers several OLED TVs, which tend to cost more, and because it stopped making lower-end LED/LCD sets. (See the best 65-inch TVs under $1,000.)

As in the 70-inch size category, Hisense, TCL, and Vizio appear to be good options for those on tighter budgets. Their better-performing sets tend to be pricier but still less expensive than comparable TVs from LG, Samsung, and Sony. Hisense has the best balance of price and performance of the group. But given the wide differences in performance and price between the best- and worst-performing models within these brands, you should look at specific models to determine the best value.

If you’re shopping for a 55- to 60-inch set, you’ll see a particularly wide range of prices and brands. That’s because some TVs this size are relatively bare-bones when it comes to features, while others come loaded with lots of features. These can include 120Hz refresh rates, full-array LED backlights with local dimming, more effective HDR performance, and special gaming features, such as low-latency modes and variable refresh rates.

Average prices go from a low of $342 (for Toshiba, which makes Fire TV Edition sets sold at Amazon and Best Buy) to a high of $1,034 (Sony’s average). As we note above, Sony focuses on higher-priced sets, and both Sony and LG’s average prices are pulled up by their OLED sets—these TVs can look great, but they tend to cost more than all but the very best LED/LCD models.

Two years ago, Vizio began offering OLED TVs, but that hasn’t yet had a big impact on its average price, because the majority of its sales are still less expensive LED/LCD TVs.

For those shopping for a TV in this size range, CR’s analysis shows that Samsung, Sony, and LG again tend to have the highest-performing TVs—along with the most expensive ones.

Of these three brands, LG sets seem particularly attractive, with a high Overall Score and an average price below these two other brands’ average prices. In last year’s analysis, however, LG’s average price was much closer to the lower-tier brands’. This could be in part because of LG offering 48-inch OLED TVs. This year, there’s a bigger price spread between the major and secondary brands. That could be because major brands tend to adopt the newest technologies first.

These days, 32-inch TVs have largely been commoditized; most are either 720p or 1080p regular high-definition TVs rather than 4K models, and there are even some low-priced basic models that lack a smart TV feature.

You may notice that Samsung is missing from this size category; there weren’t enough tested models in our analysis this year for it to be included. It’s the only brand in our current ratings that offers 32-inch 4K TVs with HDR, but those sets are more expensive, and consumers don’t seem to want to pay for the higher resolution in sets this small. Samsung does offer a number of less expensive HD sets, which are in our ratings. Shoppers seem to buying based on price rather than brand.

Reliability problems appear to be less of an issue, based on our surveys, because TVs are among the more reliable products Consumer Reports analyzes. But not all brands do as well as others, which is why you should check a brand’s reliability in our TV ratings.

Because most sets are now smart TVs that connect to the internet, we’ve added privacy and security scores to our ratings. We evaluate the various ways TV brands collect, use, and share consumer data; how well they protect it; and how transparent they are about their data practices.

Last, consider the manufacturer’s warranty, which could be shorter with an off-brand TV. Most of the TVs in our ratings carry 1-year parts and labor warranties, but that can vary, so check before you buy.

I"ve been a tech journalist for more years than I"m willing to admit. My specialties at CR are TVs, streaming media, audio, and TV and broadband services. In my spare time I build and play guitars and bass, ride motorcycles, and like to sail—hobbies I"ve not yet figured out how to safely combine.

Are colour OLED displays ready to offer a better alternative to TFT-LCDs, and where do today’s state-of-the-art TFT-LCDs remain strong?We all know that colour graphical display can seriously enhance the user experience your application will deliver. So let"s re-cap on the advantages both TFT and OLED technology offer.

TFT-LCDmaturity means competitive prices, good quality and reliability and available in a wide range of sizes - typically 1-21" for industrial embedded applications.

Operating principle: in similar ways to a monochrome STN, twisted liquid-crystal columns create waveguides to direct light from the display backlight through polarising filters. An electric field applied across ITO electrodes changes the crystal alignment to prevent the light passing and make specific locations appear dark. Unlike STN, however, the TFT-LCD contains red, green and blue filters; a thin-film transistor embedded in every sub-pixel modulates the light intensity to mix the desired colour. TFT-LCDs can display millions of colours, and response times can be fast enough to support full-frame-rate video or smooth animations.

Performance: Standard TFT-LCDs do have some limitations, however. Contrast can be limited, and colour-inversion can be perceived at extreme viewing angles. Typical contrast ratio is about 400:1 with viewing angles of L70/R70/T70/B60.

Improvements: IPS (In-Plane Switching), aka Super-TFT, displays arrived to overcome these drawbacks. In IPS, changes in crystal orientation happen in the same plane as the glass sheets that constitute the display. Pixels are dark in the off state instead of in the on state, which enables the display to appear true back when powered down. Contrast and colour fidelity are improved, and also more consistent, even at wider viewing angles than a standard TFT-LCD can manage. What’s more, there are no distracting bright-pixel defects, which can occur when a transistor fails in a conventional TFT-LCD.

Sleek, Efficient Design: A Organic LED (OLED) displays can be made lighter and thinner than conventional or Super TFT, partly because no backlight is required. No backlight means they also consume less power, which has been the key to their success in the premium smartphone sector and is also driving adoption in mobile industrial and medical applications - such as wearable medical monitors, tele-health equipment, cordless industrial panels, and mobile robotics.

Bright and Beautiful: Their light weight and low profile allow OLED displays to be fixed to the surface of an enclosure, even if the surface is curved. This is easier and more economical than designing an aperture and making provision for mounting a TFT-LCD. The wider temperature range of OLEDs also makes them a robust choice for industrial applications or use outdoors.

Passive-Matrix OLED (PMOLED) displays can be monochrome or – with the inclusion of RGB sub-pixels -colour. On the other hand, PMOLEDs can suffer from limited frame rates at larger displays sizes, so Active-Matrix (AMOLED) technologyintroduces a thin-film transistor per pixel that allows each to remain turned on for as long as needed. An AMOLED display can be the best choice if a large, bright colour display is required.

Going the TFT-LCD route, especially given the flexibility to choose standard or IPS/Super-TFT, provides a wide choice of displays that are cost-effective, readily available in numerous sizes, and easily capable of displaying full-frame-rate video and smooth animations.

On the other hand, AMOLED displays can deliver superior optical performance and wider viewing angles, with lower power consumption, reduced weight, and the engineering and aesthetic advantages of the extremely thin and flexible substrate.

Quantum Dot OLED TVs are expected to finally go real by the end of 2021. As the name suggests, these TVs will use Quantum Dot technology to enhance and improve the existing OLED panels.

How exactly are QD-OLED displays different from current OLED displays manufactured by LG Displays and from Samsung’s existing QLED TVs? This year we witnessed a surge in mini LED TVs which will be priced a little below OLED TVs. So let’s compare these different TV technologies to better understand which one is better and why.

To understand the difference between these display technologies and why they exist, it must first be cleared that the OLED displays on TVs are not the same as OLED displays on phones.

On your phones, the OLED panels have red, green, and blue subpixels that are self-emissive or emit their own red, green, and blue light – and can be individually powered on or powered off.

Making similar OLED panels for large TVs with individual Red, Green and Blue subpixels, however, poses several manufacturing and longevity challenges. In fact, only one such TV was ever launched – the Samsung KE55S9C 55-inch UHD OLED- which was introduced in 2013.

The technology wasn’t scalable for larger resolution or bigger displays and thus Samsung shifted to Quantum Dots based QLED technology for its premium TVs.

The white OLED light is achieved by using Blue and Yellow substrate. Different colors for four sub-pixels (R, G, B, W) are achieved by using a RGBW color filter layer over the essentially white OLED subpixels.  This works because a single color OLED panel is easier to manufacture and decays uniformly – which is to say that your TV will age to be less bright but the backplane light shall still remain uniformly blue or uniformly yellow.

The color filter film used in front of OLED subpixels, however, is not an ideal solution. The filters work by blocking particular colors of light thus reducing brightness, and as the Blue OLED material decays over time, Red, Green, and Blue colors are affected differentially (the decay is not the same for all three colors resulting in color shifts, burn-in and other issues).

In TVs, Quantum Dots are excited by higher energy or lower wavelength light than the emission color of the dot. To excite green and red color quantum dots, TV manufacturers thus use blue light and for blue subpixels, they let the blue light pass through as-is.

Colors are converted on red sub-pixels by red quantum dots and green sub-pixel by green quantum dots. Using this technology, the end result is similar to what you’d get with individual Red, Green, and Blue sub-pixels as with AMOLED displays on phones.

Another benefit of this implementation over color filter is that as the Blue OLED lights get dimmer with time, the red and green light getting out of the quantum dots will dim proportionally.

OLED TVs today use LG Display panels that have a white pixel along with red, green, and blue sub-pixels (and are also referred to as White OLED). This is used for enhancing brightness but reduces color vibrance. Upcoming QD-OLED panels will, in a way, re-instate RGB OLED with deeper, brighter, and more vibrant colors.

OLED technology is known to have problems with aging, but the current crop of OLED TVs handle this remarkably well. There are negligent chances that users will face issues like OLED burn-ins over a life span of 5 to 8 years.

One problem is that Quantum dots on the QD OLED TVs get excited by UV light falling on the TV from the outside. Secondly, Quantum Dot color conversion materials don’t always capture the entire blue light that is used to excite them and some of it may bleed into Red and Green subpixels.

To counter these problems, Samsung Displays is likely to use some sort of color filter which is likely to be eliminated as we progress to second or third-generation QD-OLED panels. It remains to be seen how much brightness penalty is incurred meanwhile.

Now that we have discussed how Quantum dots are enhancing existing OLED TVs, you might be wondering how the Quantum Dot technology is implemented on existing Samsung QLED TVs.

A QLED TV works just like LCD TVs, but a Quantum Dot Enhancement Film( QDEF) is used in front of the Blue LED backlight to convert portions of the blue light to Red and Green in order to get pure White light. This helps enhance brightness and achieve a wider color gamut for better HDR performance.

QLED TVs are better at avoiding the backlight bleed into the display colors as compared to conventional LED or mini LED TVs. Samsung’s high-end QLED models can also get brighter than TV OLED displays. Color conversion is still done using a color filter in front of the LCD module.

LED TVs don’t have self-emissive pixels and it’s not possible to turn off individual pixels. The LCD substrate merely blocks the white light from the backlight to portray blacks, resulting in slightly greyish blacks more noticeable in dark ambiance. The contrast and black level can however be improved by turning off a portion or zone of the backlight.

That’s where mini LED TVs come in. These TVs have an array of mini LEDs behind the screen which can be individually turned off for a section of the screen. These mini LEDs don’t map pixels one to one, but having more zones helps with better local dimming control and thus enhances quality over conventional edge-lit LED displays.

Samsung Displays is manufacturing QD-OLED displays but Samsung Electronics isn’t keen on adopting the technology. That’s because Samsung has been marketing QLED as superior to OLED panels for years and transitioning back to OLED or OLED-based TVs will make them lose face.
