a line of extreme and ultra-narrow bezel LCD displays that provides a video wall solution for demanding requirements of 24x7 mission-critical applications and high ambient light environments

Many Apple products use liquid crystal displays (LCD). LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen. Each pixel has three separate subpixels—red, green and blue—that allow an image to render in full color. Each subpixel has a corresponding transistor responsible for turning that subpixel on and off.

Depending on the display size, there can be thousands or millions of subpixels on the LCD panel. For example, the LCD panel used in the iMac (Retina 5K, 27-inch, 2019) has a display resolution of 5120 x 2880, which means there are over 14.7 million pixels. Each pixel is made up of a red, a green, and a blue subpixel, resulting in over 44 million individual picture elements on the 27-inch display. Occasionally, a transistor may not work perfectly, which results in the affected subpixel remaining off (dark) or on (bright). With the millions of subpixels on a display, it is possible to have a low number of such transistors on an LCD. In some cases a small piece of dust or other foreign material may appear to be a pixel anomaly. Apple strives to use the highest quality LCD panels in its products, however pixel anomalies can occur in a small percentage of panels.

In many cases pixel anomalies are caused by a piece of foreign material that is trapped somewhere in the display or on the front surface of the glass panel. Foreign material is typically irregular in shape and is usually most noticeable when viewed against a white background. Foreign material that is on the front surface of the glass panel can be easily removed using a lint free cloth. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or Apple Retail Store.

For this optical effect, view this on LCD instead of CRT or plasma. If using motion blur reduction (e.g. ULMB, BFI, or interpolation), turn that feature off temporarily for this animation demo. Another great TestUFO animation is TestUFO Persistence-of-Vision.

Motion blur on modern digital displays are reduced via strobing or black frame insertion (BFI) to lower persistence. Many LCD gaming monitors use strobe backlights (such as ULMB) that flicker at the same frequency of the refresh rate, in order to reduce motion blur.

It is an immutable constant (like the speed of light) where you can’t get less display motion blur than this number. Blur Busters Law assumes perfect squarewave persistence, where GtG is 0ms at both leading and trailing edge. So any display with GtG above 0 is always worse than Blur Busters Law.

Assumptions: The exact Blur Busters Law minimum is achieved only if pixel transitions are fully square-wave (0ms GtG) on fully-sharp sources (e.g. VR, computer graphics). Actual MPRT numbers can be higher.Slow GtG pixel response will increase numbers above the Blur Busters Law guaranteed minimum motion blur. Source limitations (e.g. slow camera shutter, video blur, unfocussed camera) also adds extra motion blur above-and-beyond the display.

Assumptions: The exact Blur Busters Law minimum is achieved only at one square-wave flash per frame, during imperceptible strobe crosstalk. Frame rate matching refresh rate matching strobe rate. Any curves in the flash curve away from its peak level (e.g. CRT phosphor fade, plasma/DLP multi-pulsing, etc) will muddy the math (e.g. phosphor ghosting, rainbow blurs, etc). Very bad strobe crosstalk (GtG taking much longer that it overlaps two pulses) can also affect motion quality.

These are additional blur-like artifacts above-and-beyond the guaranteed minimum motion blur mandated by Blur Busters Law. See LCD Motion Artifacts and LCD Overdrive Artifacts for examples.

For low Hz where the Hz is so low, the normally high-frequency stutter no longer blends seamlessly into display motion blur. If you stare at www.testufo.com on a common 60 Hz LCD screen, you will see higher framerates tend to show motion blur while lower framerates tend to stutter (vibrate).

However, once the stutter is high-frequency (e.g. 60fps or 120fps) the 60 or 120 stutters per second vibrates so fast, it just blends into motion blur. The “stutters-blends-to-motion-blur” effect is more easily understood in this variable refresh rate simulation, if viewed on a common LCD (non-strobed):

At lower refresh rates such as 60 Hz or 75 Hz, amplified flicker can occur because of the flicker curve and flicker duty cycle. On CRTs and plasmas, phosphor gives a gentler fade than square-wave strobe backlight flashes. In addition, global flash strobing (e.g. ULMB) also varies average picture brightness more than a scanning flash (e.g. CRT).

This is why the equivalent refresh rate (e.g. 75 Hz) flickers a lot more on strobed LCD displays than on CRT/plasma displays, because you’re comparing square-waved strobing (e.g. ULMB) versus curved strobing (e.g. CRT).

We simply use use overkill BFI/strobe rate to compensate for the lack of flicker curve-softening (phosphor fade). Thankfully, 120 Hz square wave strobing (ULMB or LightBoost) still flickers a lot less than an old 50 Hz or 60 Hz CRT.

More details on these changes are provided below. In certain apps, these changes can lead to the “square box” symptoms when displaying certain international text.

If a Windows Phone app directly depends on one of the fonts listed above for displaying certain Unicode characters and does not make use of font fallback mechanisms provided by Windows, the result would be characters displayed as “square box” glyphs.

If an app depends on one of these fonts for displaying certain Unicode characters and does not make use of font fallback mechanisms provided by Windows, and if the optional font package containing that font is not installed on the system (typically because the system and user profiles are not configured to have the associated language enabled), then the result would be characters displayed as “square box” glyphs.

A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technologyactive matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments.

In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark"s ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968. In 1971, Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated a 2-by-18 matrix display driven by a hybrid circuit using the dynamic scattering mode of LCDs.T. Peter Brody, J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories developed a CdSe (cadmium selenide) TFT, which they used to demonstrate the first CdSe thin-film-transistor liquid-crystal display (TFT LCD).active-matrix liquid-crystal display (AM LCD) using CdSe TFTs in 1974, and then Brody coined the term "active matrix" in 1975.high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.

The circuit layout process of a TFT-LCD is very similar to that of semiconductor products. However, rather than fabricating the transistors from silicon, that is formed into a crystalline silicon wafer, they are made from a thin film of amorphous silicon that is deposited on a glass panel. The silicon layer for TFT-LCDs is typically deposited using the PECVD process.

The twisted nematic display is one of the oldest and frequently cheapest kind of LCD display technologies available. TN displays benefit from fast pixel response times and less smearing than other LCD display technology, but suffer from poor color reproduction and limited viewing angles, especially in the vertical direction. Colors will shift, potentially to the point of completely inverting, when viewed at an angle that is not perpendicular to the display. Modern, high end consumer products have developed methods to overcome the technology"s shortcomings, such as RTC (Response Time Compensation / Overdrive) technologies. Modern TN displays can look significantly better than older TN displays from decades earlier, but overall TN has inferior viewing angles and poor color in comparison to other technology.

Most TN panels can represent colors using only six bits per RGB channel, or 18 bit in total, and are unable to display the 16.7 million color shades (24-bit truecolor) that are available using 24-bit color. Instead, these panels display interpolated 24-bit color using a dithering method that combines adjacent pixels to simulate the desired shade. They can also use a form of temporal dithering called Frame Rate Control (FRC), which cycles between different shades with each new frame to simulate an intermediate shade. Such 18 bit panels with dithering are sometimes advertised as having "16.2 million colors". These color simulation methods are noticeable to many people and highly bothersome to some.gamut (often referred to as a percentage of the NTSC 1953 color gamut) are also due to backlighting technology. It is not uncommon for older displays to range from 10% to 26% of the NTSC color gamut, whereas other kind of displays, utilizing more complicated CCFL or LED phosphor formulations or RGB LED backlights, may extend past 100% of the NTSC color gamut, a difference quite perceivable by the human eye.

The transmittance of a pixel of an LCD panel typically does not change linearly with the applied voltage,sRGB standard for computer monitors requires a specific nonlinear dependence of the amount of emitted light as a function of the RGB value.

In-plane switching was developed by Hitachi Ltd. in 1996 to improve on the poor viewing angle and the poor color reproduction of TN panels at that time.

Most panels also support true 8-bit per channel color. These improvements came at the cost of a higher response time, initially about 50 ms. IPS panels were also extremely expensive.

In 2004, Hydis Technologies Co., Ltd licensed its AFFS patent to Japan"s Hitachi Displays. Hitachi is using AFFS to manufacture high end panels in their product line. In 2006, Hydis also licensed its AFFS to Sanyo Epson Imaging Devices Corporation.

Less expensive PVA panels often use dithering and FRC, whereas super-PVA (S-PVA) panels all use at least 8 bits per color component and do not use color simulation methods.BRAVIA LCD TVs offer 10-bit and xvYCC color support, for example, the Bravia X4500 series. S-PVA also offers fast response times using modern RTC technologies.

A technology developed by Samsung is Super PLS, which bears similarities to IPS panels, has wider viewing angles, better image quality, increased brightness, and lower production costs. PLS technology debuted in the PC display market with the release of the Samsung S27A850 and S24A850 monitors in September 2011.

Due to the very high cost of building TFT factories, there are few major OEM panel vendors for large display panels. The glass panel suppliers are as follows:

External consumer display devices like a TFT LCD feature one or more analog VGA, DVI, HDMI, or DisplayPort interface, with many featuring a selection of these interfaces. Inside external display devices there is a controller board that will convert the video signal using color mapping and image scaling usually employing the discrete cosine transform (DCT) in order to convert any video source like CVBS, VGA, DVI, HDMI, etc. into digital RGB at the native resolution of the display panel. In a laptop the graphics chip will directly produce a signal suitable for connection to the built-in TFT display. A control mechanism for the backlight is usually included on the same controller board.

The low level interface of STN, DSTN, or TFT display panels use either single ended TTL 5 V signal for older displays or TTL 3.3 V for slightly newer displays that transmits the pixel clock, horizontal sync, vertical sync, digital red, digital green, digital blue in parallel. Some models (for example the AT070TN92) also feature input/display enable, horizontal scan direction and vertical scan direction signals.

New and large (>15") TFT displays often use LVDS signaling that transmits the same contents as the parallel interface (Hsync, Vsync, RGB) but will put control and RGB bits into a number of serial transmission lines synchronized to a clock whose rate is equal to the pixel rate. LVDS transmits seven bits per clock per data line, with six bits being data and one bit used to signal if the other six bits need to be inverted in order to maintain DC balance. Low-cost TFT displays often have three data lines and therefore only directly support 18 bits per pixel. Upscale displays have four or five data lines to support 24 bits per pixel (truecolor) or 30 bits per pixel respectively. Panel manufacturers are slowly replacing LVDS with Internal DisplayPort and Embedded DisplayPort, which allow sixfold reduction of the number of differential pairs.

The bare display panel will only accept a digital video signal at the resolution determined by the panel pixel matrix designed at manufacture. Some screen panels will ignore the LSB bits of the color information to present a consistent interface (8 bit -> 6 bit/color x3).

With analogue signals like VGA, the display controller also needs to perform a high speed analog to digital conversion. With digital input signals like DVI or HDMI some simple reordering of the bits is needed before feeding it to the rescaler if the input resolution doesn"t match the display panel resolution.

Fresh KDS is a standalone, iPad-based KDS system that integrates with several popular POS systems like Square and Clover. There are currently more integrations in the works, with industry stalwarts Toast, Revel, Lightspeed, TouchBistro, and Aloha.

However, Fresh KDS could have scored higher if it offered recipe lookup tools (like Toast, Revel, and Epson) or had the ability to operate without an internet connection (like Toast, Revel, and Epson). Currently, like Lightspeed Kitchen and Square KDS, Fresh KDS needs a strong internet connection to function.

Square for Restaurants is a cloud-based POS system best suited for restaurants on a budget, as the POS software has a forever free plan and an advanced plan that’s just $60 per month. In particular, we recommend Square for Restaurants for food trucks, QSRs, cafes, slice shops, and bakeries.

If you’re using the free version of Square for Restaurants, the KDS is just $20 per device. If you’re on Square for Restaurants Plus or Premium, KDS software for unlimited devices is included for free.

Square earned a3.22 out of 5 on our KDS scoring system. Square’s affordable pricing—it outscored the other systems on this list for price—and the ability to use hardware you already own make Square for Restaurants the best KDS for restaurants on a budget.

While you can customize your KDS views in dozens of ways, from the ticket size to the alert colors, Square is not overwhelmingly customizable. So it’s an excellent fit for small restaurants that want a simple KDS solution. If you want more customization options, you should try Toast (for a POS option) or Epson (for a freestanding solution).

Square’s KDS operates on iPads running iOS 13 or later. You can download the KDS software from the Apple App Store, then operate the KDS on iPads you already own. Alternatively, you can purchase iPads from Square. The Square KDS can receive orders from Square for Restaurants operating on Square Register or iPads, Square POS operating on iPads, Android devices, Square Register, and Square Terminal devices, orders from the Square Online store, and any third-party delivery partner or kiosk partner sending orders to your Square POS.

All-Day View Like other systems on this list, Square supports an All-Day count view. Plus, Square goes the extra mile and adds color coding to the All-Day count, so your cooks and expediters only need to glance to see which tickets are waiting on popular dishes.

Every other KDS on this list processes voided items as separate tickets. These tickets will typically be marked with the same ticket or table number as the original ticket, but this can still lead to over-prepped food on a busy night. Square displays voided items in red directly on the original ticket. So, if table 25 cancels their soup order, your cooks will see it in real time.

Customizable views On each Square KDS, you can individually adjust the text size, the number of tickets displayed per page, and notification settings for new orders. This way, your cooks can view orders the way they prefer.

Free online ordering All of the systems on this list display online orders in the KDS. But Square for Restaurants is the only POS that includes a free online ordering site. In addition to receiving online orders directly in your KDS order stream, Square users have the comfort of knowing they aren’t paying any extra fees for those orders.

For Free Square for Restaurants users, the Square KDS costs $20 per tablet, per month. Plus and Premium subscribers can use the KDS for free on unlimited devices.

See why we recommend Square for Restaurants for food trucks and learn more about Square for Restaurants POS features in our full Square for Restaurants review.

Lightspeed Kitchen earned a 3.19 out of 5.00on our KDS ranking, putting it right on Square’s heels. It earned points for its recipe lookup “Show and Tell” functions and for its affordability. But Lightspeed Kitchen is not quite as customizable as Toast and Revel’s KDS (though restaurants looking for a simplified solution might prefer this).
