Competition and innovation are hallmarks of the consumer electronics market which has experienced practically uninterrupted growth for decades. Many consumers own a range of electronic devices (laptop, smartphone, tablet, TV, etc.), each of which is available in a plethora of options: brands; grades, formats; technologies. This technological array is further complicated by marketing terms that try to differentiate between competing products. Acronyms like OLED and LCD are rife in the electronics sector, but what is the actual difference between the two?

OLEDs refresh time is in microseconds that with faster response time, as opposed to LCDs’ milliseconds. In addition, the oled reflesh time would be same in high temperature and low temperature. while to lcd screen, it reflecsh time would become slowly in low temperature.

For monochrome OLED panel manufacturers, there are Visionox, Truly, Wisechips, and RIT, Winstars in Great China area, monochrome OLED panel sources are mainly comes from these OLED panel manufacturers.

Traditional LED TVs are based on liquid crystal display (LCD) screen technology; a tried-and-tested panel structure. On an LCD screen, images are produced by a thin layer of liquid crystal solution overlaid on a transistor grid which uses small electrical charges to set the individual crystals to an open/closed state. This produces a pattern of light and dark pixels, but the light itself is produced by a bank of LEDs arranged at the edges of the screen or in a backlit array.

The best possible picture on LCD screens is produced using a full-array LED backlight with local-dimming which yields the widest possible contrast. However, LCDs comprise multiple sequential layers within the panel (color filters, polarizers, etc.) which are necessary for producing fully-saturated images but may inhibit picture uniformity and viewing angles. This also makes LED TVs thicker and heavier, rendering them undesirable for applications where reduction of thickness or weight is important.

Besides OLED panel manufacturers, OLED module manufactures are more common than OLED panel manufacturers, The processes of OLED module production are most likely to COG LCD module production, only without backlight assembly. The small OLED display module intergrate OLED panel, IC driver chip on glass, flex cable, sometimes with PCB adapter. The interfaces of small OLED display modules are available in IIC, SPI, MCU, MIPI interface, that they are easily to be used in common master board, such as Raspberry PI, Arduino, STM32, ESP8266.

China OLED panel manufacturers have BOE, Tianma, Visionox, EDO,  they are tier 1 OLED display manufacturers in China, they have the newest generation production lines for OLED display panels, making AM-OLED panels and flexible OLED displays, such as for smartphone screens. Besides Samsung and LG in OLED display domain(they are also the manufacturers of transparent oled display modules), China OLED manufacturers are the major manufatuers for OLED display panels market.

OLEDs circumvent each of these issues by eschewing a backlight in favor of a self-emissive panel of organic carbon-based material. This allows each subpixel onscreen to be controlled independently. Alongside greater dynamic ranges and energy efficiency, the unique characteristics of OLED panels allow for significantly fewer layers in the screen matrix. Consequently, OLED TVs are typically thinner and lighter in weight than conventional LCDs, but cost significantly more to produce than LCD displays.

Oled can emitting light by itself and no need backlight, through the use of phosphorescence (which can convert four times more electricity into light than other materials), OLEDs are significantly more power-efficient than LCDs. In fact, LCD manufacturers are trying to replicate the power advantages of OLEDs by using LEDs in some high-end TVs,

All transmissive LCD display technologies are challenged in bright sunlight, because the light reflects off the display. To mitigate the reflection, the LCDs offer a transflective mode, which is a combination of a reflective and a transmissive display, to lessen the problem but compromise on color and contrast performance in the process.

OLEDs offer great potential for efficient lighting solutions with recent reseach achieving 46 lumens per Watt (lm/W) with lifetimes greater than 10,000 hr (a standard incandescent bulb offers 14 lm/W with a 1000 hr lifetime).

Oled moduel have outstanding performance than lcd screen, even both oled module and lcd display module said they could support -40~+85°C in their datasheets, but the lcd screen always would be slightly dimmer in low temperature and fading in high temperature, it is limited by the liquild crystral characteristics, but the oled module display performance would be consistency in high temperature and low temperature working.

Oled display can be developed in more display ways than lcd display module. such as transparent Oled display module, Flexible oled display module etc, Oled display bring the better display performances than other displays. Oled display module has many advantages in contrast, brightness, and thinner than LCD display, we can get more vivid display image by using OLED display, OLED display doesn't  require the backlight unit, it is better for making transparent OLED display and flexible OLED display module.

oledvs lcd的优缺点

In this blog post, Avantama explores the base functionality of OLED Vs. LCD  to explain how these two display technologies differ.

To color AM oled display module, AM-OLEDs offer the best video you’re going to see from display technology. Their color can reach higher NTSC standards. Contrast ratios in the range of 1,000,000 to 2,000,000:1 make those colors look even more brilliant theoretically. But in fact, as the IPS LCD or LTPS TFT LCD technology are going to mature, the color tft lcd screen is almost near to the color oled display module in viewing angle and contrast in display performance nowadays, please see the comparision picures as below, we use IPS tft lcd vs OLED module as below, because IPS tft has the outstanding performance in viewing angle, then you can the ips tft lcd is almost has similar display performance as the color oled display (of course, AM-oled is still little better in wide viewing angle, but not so much). but the cost of oled screen are 2~3 times than tft lcd screen, so for color display, we don't think it is necessary to choose oled display. for tft lcd module, the tft lcd glass and backlight can be made more thinner than before, its thickness can be almost similar nowadays.

Displays - Pi5 Displays ; 2.13 inch E-ink Display HAT for Pi · Part No: W15084 · R326.00 (Inc Tax: R374.90) ; 2.13 inch flexible E-ink display · Part No: W14986.

OLED display module is thiner than traditional LCD display, because OLED screen no need the backlight unit, it can emit light by itself. Besides the thinner, OLED screen could be made in flexible, the newest fexible screen all are made by oled module, because low-temperature processing oled emit light materials can be evaporated to the flexible subplated, while tft lcd screen can not make it like that, because the liquild crystal have to be sealed inside the tft lcd cell, the flexible subplated can not provide a reliable sealing condition for flexible tft lcd screen.

To oled display module, especially for monochrome oled,  its power consumption is related to the display content, the less display content, the lower power consumption. Such as an 0.96” oled 128x64 pixel, with SSD 1306 IC driver, I2C oled interface, the current for full display on would be 12.3 mA, and the current for 50% display pixles on would be 7.3 mA. These current is included the OLED driver’s current and oled display screen’s current. The oled power consumption would be also related to the brightness level what it is on working, the higher brightness means higher driver voltage, higher current and higher power consumption.

LCD OLED

More peoples concern that OLED has high display contrast and can get more vivid display colors than lcd screen, the oled contrast can reach 10000:1, while a tft lcd display, its display contrast only around 1000:1. because OLED has a more blacker background in the non-display area, while to the lcd screen, it has more or less light leak on the non-display area, it lead to the lcd display can not get a better display contrast than OLED display module.

Currently, OLED televisions outperform traditional LED products on several fronts. They come in a versatile range of formats: panels as large as 88-inches satisfy the demands of premium TV displays; while smaller AMOLED (active-matrix OLED) screens set the benchmark of picture quality in the smartphone industry. Foldable OLED devices have finally begun to enter the consumer electronics market too, fulfilling a long-standing promise from proponents of the technology.

In the same time, OLED module has better wide temperature than lcd screen, it has without the response time problem when in low temperature and display fade in high temperature as comparing to lcd screen. so oled module is more suitable for sunligh readable display.

OLEDs are emissive, similar to plasma displays and cathode ray tubes. They degrade over time. LCDs are transmissive displays that operate by filtering a backlight. LCDs typically last as long as their backlights, which also degrade over time or can fail catastrophically. Early in the development of OLED displays, the lifetime (defined as the time it takes for the display to reach 50% of the original luminance) was lower than typical LCD lifetimes. However, with tremendous progress in materials development, OLED displays have lifetimes comparable to or better than LCDs. Many OLED displays currently on the market have lifetimes exceeding 50,000 hr. In addition, lifetimes for OLED materials being developed by Cambridge Display Technology, Universal Display and others have lifetimes 2-3 times greater than typical LCDs. Some are in products today and more are expected to reach the market within coming years. Such as Maclight 0.96” oled in white color, its lifetime can be 50,000 hours in 60cd/m2 brightness display. But the higher brightness of OLED, its lift time would be decreased accordingly.

To monochrome oled display module, it is correct. Monochrome oled have higher contrast than monochrome lcd, because its background is more blacker than monochrome lcd, monochrome oled background without light leak as monochrome lcd, so its contrast is better than monochrome stn lcd or TN lcd display. and the monochrome lcd (STN lcd or TN lcd) has the viewing angle limited, its viewing angle is 120° (max), but oled screen could be 180°, that is without viewing angle limited.
