smallest 4k lcd panel factory

Think that iPad"s Retina display is sharp? Ortustech would argue that it"s old hat. The company"s new LCD occupies a similar dimension at 9.6 inches, but it also carries an extremely dense 3,840 x 2,160 resolution -- making it the world"s smallest 4K display at a time when most everyone else is struggling to produce the giant variety. Like with the Japanese firm"s earlier 4.8-inch record-setter, the trick rests in a Hyper Amorphous Silicon TFT (HAST) that lets in more light per pixel and prevents that virtually seamless 458PPI image from becoming unusably dim. Test samples are rolling off the factory lines in November, although we"re not expecting to see Ortustech displays in our tablets anytime soon: sheer performance demands aside, the narrower 160-degree viewing angles and lower 72 percent color gamut better suit the 4K screen to pro video cameras and medical monitors that thrive on sharpness over anything else.

Tokyo, October 23, 2012 - ORTUS TECHNOLOGY CO., LTD (ORTUSTECH, HQ in Tokyo, Hino, President Mr.Ichiro Ohno) announced today that it has developed 9.6-inch color liquid crystal display, which is the world"s smallest size screen＊ realizes 4K2K full-pixels (3840x2160), and start sample delivery from November 2012.

4K2K display market is expected to grow rapidly as the next generation standard of high-quality display. Along with ORTUSTECH original HAST® technology (Hyper Amorphous Silicon TFT) which enables high-resolution display at high-aperture ratio, fine-pitch assemble technology, liquid crystal alignment technology, TFT drive technology which makes panel performance maximize, contribute to realize 4K2K full-pixels (3840x2160) image on 9.6-inch small size panel.

The natural and three-dimensional expression is realized by achieving overwhelming higher resolution (458ppi), which exceed discrimination limit of human eyes. 9.6-inch 4K2K display will be well suited to professional video equipment and medical equipment where clear and high resolution is demanded, such as broadcasting 4K2K camera monitor.

4K is all the rage as product manufacturers, broadcasters, and content producers anticipate adoption of UltraHD as a viable consumer platform. More pixels means greater resolution and larger average screen sizes, right?

Ortustech first gained notoriety in 2010 by packing a 1920x1080 HD into a 4.8 inch screen. Building on its mission to create small form factor high resolution displays, the company has announced a 4K2K (3840x2160) screen that’s only 9.6 inches!

According to Ortustech’s press release, “the natural and three-dimensional expression is realized by achieving overwhelming higher resolution (458ppi), which exceed discrimination limit of human eyes. 9.6-inch 4K2K display will be well suited to professional video equipment and medical equipment where clear and high resolution is demanded, such as broadcasting 4K2K camera monitor.”

For a touch screen, it looks like the smallest one at the link above is 15.6, obviously a laptop screen. Smaller touch screen would be nice for a pi based small portable computer or tablet. The new pi 4 has me thinking about the possibilities.

from my experiences with a 14" 6K notebook screen and a 13" full-HD touch screen for my Pi you"ll probably will have no benefit from 4K displays smaller than that at all.

Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of electroluminescent organic/inorganic materials that generate light when a current is passed through the material. LCD, OLED and microLED displays are driven using LTPS, IGZO, LTPO, and A-Si TFT transistor technologies as their backplane using ITO to supply current to the transistors and in turn to the liquid crystal or electroluminescent material. Segment and passive OLED and LCD displays do not use a backplane but use indium tin oxide (ITO), a transparent conductive material, to pass current to the electroluminescent material or liquid crystal. In LCDs, there is an even layer of liquid crystal throughout the panel whereas an OLED display has the electroluminescent material only where it is meant to light up. OLEDs, LCDs and microLEDs can be made flexible and transparent, but LCDs require a backlight because they cannot emit light on their own like OLEDs and microLEDs.

Liquid-crystal display (or LCD) is a thin, flat panel used for electronically displaying information such as text, images, and moving pictures. They are usually made of glass but they can also be made out of plastic. Some manufacturers make transparent LCD panels and special sequential color segment LCDs that have higher than usual refresh rates and an RGB backlight. The backlight is synchronized with the display so that the colors will show up as needed. The list of LCD manufacturers:

Organic light emitting diode (or OLED displays) is a thin, flat panel made of glass or plastic used for electronically displaying information such as text, images, and moving pictures. OLED panels can also take the shape of a light panel, where red, green and blue light emitting materials are stacked to create a white light panel. OLED displays can also be made transparent and/or flexible and these transparent panels are available on the market and are widely used in smartphones with under-display optical fingerprint sensors. LCD and OLED displays are available in different shapes, the most prominent of which is a circular display, which is used in smartwatches. The list of OLED display manufacturers:

MicroLED displays is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Like OLED, microLED offers infinite contrast ratio, but unlike OLED, microLED is immune to screen burn-in, and consumes less power while having higher light output, as it uses LEDs instead of organic electroluminescent materials, The list of MicroLED display manufacturers:

LCDs are made in a glass substrate. For OLED, the substrate can also be plastic. The size of the substrates are specified in generations, with each generation using a larger substrate. For example, a 4th generation substrate is larger in size than a 3rd generation substrate. A larger substrate allows for more panels to be cut from a single substrate, or for larger panels to be made, akin to increasing wafer sizes in the semiconductor industry.

First, you need to check whether this display has On-cell or In-cell touch panel, if has, it only needs to add a cover glass on it. If not, it needs an external touch panel.

Because the shape of the cover glass depends on the design of the clients, to avoid infringement of appearance, most of the developers need different customized touch panels.

The biggest failing of the ViewSonic VG2756-4K is its mediocre 949:1 contrast ratio, which is okay in a budget monitor but harder to swallow in a model that usually costs around $500. Its performance in our color-accuracy tests was also mediocre. It has many of the other features we look for in a good 4K monitor, including a USB-C port, a USB hub (along with an Ethernet port), a flexible stand, and a three-year warranty. But its image quality is a step down from that of the Dell S2722QC and the HP Z27k G3.

The LG 27BK67U-B and the LG 27BL55U-B are 4K monitors with good color that cost less than $400; the 67U-B has a USB hub and USB-C, whereas the 55U-B omits those features and generally costs less. But in our tests both monitors suffered from image retention, leaving behind noticeable afterimages that other budget monitors we tested didn’t have.

We dismissed the ViewSonic VP2768-4K and the BenQ PD2700U for their lack of USB-C connectivity, which is a must-have in $400-and-up monitors these days.

We dismissed some 32-inch monitors without testing them because they were missing one or more of the features we were looking for. The ViewSonic ColorPro VP3268-4K lacked a USB-C port and didn’t cost much less than monitors that had one, and the BenQ EW3280U omitted a USB hub and had a limited stand that tilted the monitor up and down only.

Most companies have stopped making new 24-inch 4K monitors, but we did test the LG 24UD58-B against the Dell P2415Q in 2019. The LG’s screen was less accurate than the Dell’s by a wide margin. This model also had fewer ports (two HDMI ports and one DisplayPort connection), and its stand tilted the monitor up and down only.

We didn’t test the 24-inch LG UltraFine 4K Display, which Apple recommends for Macs that use Thunderbolt 3 ports. It also costs more than our other picks.

With Delta E < 2 color accuracy, the ColorPro® VP2756-4k delivers stunning color reproduction that ensures the colors in your videos and photos are true-to-life and nearly indistinguishable from the color seen by the naked eye.

One of today’s modern technological wonders is the flat-panel liquid crystal display (LCD) screen, which is the key component we find inside televisions, computer monitors, smartphones, and an ever-proliferating range of gadgets that display information electronically.What most people don’t realize is how complex and sophisticated the manufacturing process is. The entire world’s supply is made within two time zones in East Asia. Unless, of course, the factory proposed by Foxconn for Wisconsin actually gets built.

Liquid crystal display (LCD) screens are manufactured by assembling a sandwich of two thin sheets of glass.On one of the sheets are transistor “cells” formed by first depositing a layer of indium tin oxide (ITO), an unusual metal alloy that you can actually see through.That’s how you can get electrical signals to the middle of a screen.Then you deposit a layer of silicon, followed by a process that builds millions of precisely shaped transistor parts.This patterning step is repeated to build up tiny little cells, one for each dot (known as a pixel) on the screen.Each step has to be precisely aligned to the previous one within a few microns.Remember, the average human hair is 40 microns in diameter.

On the other sheet of glass, you make an array of millions of red, green, and blue dots in a black matrix, called a color filter array (CFA).This is how you produce the colors when you shine light through it.Then you drop tiny amounts of liquid crystal material into the cells on the first sheet and glue the two sheets together.You have to align the two sheets so the colored dots sit right on top of the cells, and you can’t be off by more than a few microns in each direction anywhere on the sheet.The sandwich is next covered with special sheets of polarizing film, and the sheets are cut into individual “panels” – a term that is used to describe the subassembly that actually goes into a TV.

For the sake of efficiency, you would like to make as many panels on a sheet as possible, within the practical limitations of how big a sheet you can handle at a time.The first modern LCD Fabs built in the early 1990s made sheets the size of a single notebook computer screen, and the size grew over time. A Gen 5 sheet, from around 2003, is 1100 x 1300 mm, while a Gen 10.5 sheet is 2940 x 3370 mm (9.6 x 11 ft).The sheets of glass are only 0.5 - 0.7 mm thick or sometimes even thinner, so as you can imagine they are extremely fragile and can really only be handled by robots.The Hefei Gen 10.5 fab is designed to produce the panels for either eight 65 inch or six 75 inch TVs on a single mother glass.If you wanted to make 110 inch TVs, you could make two of them at a time.

The fab is enormous, 1.3 km from one end to the other, divided into three large buildings connected by bridges.LCD fabs are multi-story affairs.The main equipment floor is sandwiched between a ground floor that is filled with chemical pipelines, power distribution, and air handling equipment, and a third floor that also has a lot of air handling and other mechanical equipment.The main equipment floor has to provide a very stable environment with no vibrations, so an LCD fab typically uses far more structural steel in its construction than a typical skyscraper.I visited a Gen 5 fab in Taiwan in 2003, and the plant manager there told me they used three times as much structural steel as Taipei 101, which was the world’s tallest building from 2004- 2010.Since the equipment floor is usually one or two stories up, there are large loading docks on the outside of the building.When they bring the manufacturing equipment in, they load it onto a platform and hoist it with a crane on the outside of the building.That’s one way to recognize an LCD fab from the outside – loading docks on high floors that just open to the outdoors.

LCD fabs have to maintain strict standards of cleanliness inside.Any dust particles in the air could cause defects in the finished displays – tiny dark spots or uneven intensities on your screen.That means the air is passed through elaborate filtration systems and pushed downwards from the ceiling constantly.Workers have to wear special clean room protective clothing and scrub before entering to minimize dust particles or other contamination.People are the largest source of particles, from shedding dead skin cells, dust from cosmetic powders, or smoke particles exhaled from the lungs of workers who smoke.Clean rooms are rated by the number of particles per cubic meter of air.A class 100 cleanroom has less than 100 particles less than 0.3 microns in diameter per cubic meter of air, Class 10 has less than 10 particles, and so on. Fab 9 has hundeds of thousands of square meters of Class 100 cleanroom, and many critical areas like photolithography are Class 10.In comparison, the air in Harvard Square in Cambridge, MA is roughly Class 8,000,000, and probably gets substantially worse when an MBTA bus passes through.

The Hefei Gen 10.5 is one of the most sophisticated manufacturing plants in the world.On opening day for the fab, BOE shipped panels to Sony, Samsung Electronics, LG Electronics, Vizio, and Haier.So if you have a new 65 or 75-inch TV, there is some chance the LCD panel came from here.

The number of 4K monitors for PCs is gradually increasing. It may seem a little like speculation, but they solve various problems with displays and are smart and progressive choices offering the best display environment. EIZO"s 4K display, the FlexScan EV3237, in particular is a major contender when looking at display choices from a long-term perspective.

Full HD liquid crystal displays were once considered high-end, but in recent years, the prices have come down considerably, and today 23" full HD models have penetrated the domestic market to the point of becoming main stream. Around the time of the transition to terrestrial digital broadcasting, the shift to full HD displays accelerated. Although there was a perception of stagnation following that, the next wave has finally rolled in. Of course, this was brought about by the rise of 4K displays.

"4K" refers to horizontal resolutions of around 4,000 pixels. The "K" stands for "kilo" (thousand). As things stand, the majority of 4K displays come with 3840 x 2160 pixel (4K UHDTV) resolution, which is exactly four times the pixel count of full HD displays (1920 x 1080 pixels). There are also 4096 x 2160 pixel (DCI 4K) displays for the film industry that are referred to as 4K displays.

4K UHD is 4K as defined by the ITU (International Telecommunication Union). It has twice the horizontal and vertical resolution of full HD and has been adopted by the television industry.

DCI 4K is 4K as defined by DCI (Digital Cinema Initiatives). The horizontal resolution is higher than 4K UHD. This resolution is twice the horizontal and vertical resolution of projectors (2048 x 1080 pixels) and has been adopted by the film industry.

Against a backdrop of ever higher digital camera photograph resolutions, higher resolution content of home video cameras supporting 4K, increasingly high definition displays on smartphones and tablets, and other such developments, full HD displays on PCs are becoming less and less attractive. At the same time, interest is increasing in large screens and multi-screen environments that allow larger work spaces to increase the efficiency of multi-tasking, which is essential for PCs.

In the midst of these circumstances, EIZO introduced its much-awaited new FlexScan EV3237 display. This new flagship model with a large 31.5" wide screen (visible diagonal size: 79.9 cm) is the first of its universal displays to support 3840 x 2160 pixel 4K resolution. It"s a high-end display for a new age that meets the two needs of high-definition and a large work space with top-level specs.

That said, there are probably many out there who wonder whether it"s still too early to buy a 4K display. In this article, we"ll take a look at how the FlexScan EV3237 4K display can solve problems and complaints frequently experienced in display environments of late in Q&A format. We think you"ll see that the FlexScan EV3237 should be one of the purchase candidates on your list right now.

A The detail on displays is expressed in terms of pixel density or definition, and the numerical representation of that degree is expressed in ppi. Ppi stands for "pixels per inch." Reducing the distance between pixels (pixel pitch) without changing the screen size of the LCD panel increases the ppi, and the higher this number, the higher the definition of the display.

The 31.5" FlexScan EV3237 is viewed from a much greater distance than smartphones, tablets and laptops, so even with a pixel density of around 140 ppi, the display appears smooth and high-definition. It"s hard to tell from photographs, but watching a high-definition video at 4K resolution on a 31.5" wide screen (roughly 80 centimeters diagonally from corner to corner) is an amazing experience that cannot be enjoyed with a full HD display.

The FlexScan EV3237 can be used for either purpose. First, in the former case, the 31.5" wide LCD panel with 4K resolution offers a large work space (however, magnification via scaling also has to be taken into account; more details are provided later).

Three image signals displayed side by side using the PbyP function. The left half is 1920 x 2160 pixels, and the top and bottom of the right half are both 1920 x 1080 pixels. Taking advantage of the large 31.5" screen and high definition 4K display, a multi-display setup can be achieved with no frames between screens.

Q Full HD (1920 x 1080) and WUXGA (1920 x 1200) leave something to be desired when editing high pixel photographs and videos. Should I go with WQHD or ultra-wide (CinemaScope)? Or should I choose 4K already?

A The spread of 4K may be faster than expected. From a broadcasting standpoint, there are major movements underway in the United States, South Korea and other countries. In Japan, there is an accelerated road map being worked on for 4K/8K broadcasts. In the PC world, the environment has been prepared for HiDPI, and products have been hitting the shelves all at once. Additionally, game manufacturers have begun talking about 4K support with new games (even though the required specs are shockingly high). In the coming months, there will be increasing demand for 4K displays, and manufacturers will likely accelerate their production.

Going one notch down and choosing WQHD (2560 x 1440 pixels) or casting aside versatility and going with ultra-wide (e.g. 21:9 aspect ratio/2560 x 1080 pixels) would not be ill-advised as an "in-between" until 4K becomes main stream. These do not have the pixel density of 4K displays, so magnification with scaling is not required, and it"s easy to secure a large work space. At this point in time, they also have an advantage in terms of cost.

However, if you already have a PC environment for 4K display at this point in time, and want a high-definition display that you will use for many years to come, there is no reason to hold off on the FlexScan EV3237. Conversely, displays under 4K may quickly become obsolete, so if you are thinking of medium- to long-term use, a 4K display may work for you longer and, as a result, pay for itself over time.

EIZO"s 27" FlexScan EV2736W wide LCD. The resolution is WQHD (2560 x 1440 pixels/109ppi). Before the FlexScan EV3237, this was the flagship model of the FlexScan EV series, but if you are just now starting to look at different products, you should include 4K displays in your consideration.

Q I bought a laptop with a super high pixel density display, but it"s not practical unless I use scaling to magnify the display 150-200%. Won"t a 4K display ultimately be the same?

A As mentioned earlier, today as HiDPI has reached a practical level, more and more laptops are being equipped with high-definition LCDs. These products offer high-definition display as the selling point with the assumption that scaling will be used for magnification, so high resolution does not mean a large work space as it did when display density was assumed to be fixed.

At the same time, the pixel pitch on the FlexScan EV3237 is also narrow owing to the high-definition display. For example, if you wanted to keep the same pixel pitch (approx. 0.27mm) as a currently main stream 23" full HD display with a 4K resolution display, you would need to double the screen size with a 46" display. This is crammed into a 31.5" display, so the pixel pitch is naturally narrower.

That said, the large 31.5" screen means that it"s not so extremely fine as it would be on a 23.8" or 28" 4K display. The pixel pitch is about 0.18 mm, so if you pick the right installation location and adjust the viewing distance, it"s usable without scaling. However, when using a large 31.5" screen up close, it places more stress on the eyes and neck, so it"s advisable to use the scaling feature.

Display area at "Smaller - 100%." This is normal magnification, and the 3840 x 2160 pixel 4K resolution can be used to the fullest. The pixel density is about 140 ppi, and the pixel pitch is approximately 0.18mm. This setting is not unusable, but the screen is easier to see at "Medium - 125%" or "Larger - 150%."

A It"s necessary to be mindful of various things to mitigate the burden placed on the eyes, neck and shoulders by working on a PC. The minimum requirement of displays is that the LCD panel surface is non-glare to minimize reflection and that the brightness, height and angle can be adjusted.

The Auto EcoView feature offers both energy savings and relief for tired eyes. It is easily configured using the OSD menu from the button on the front of the LCD (left). Starting with this new model, users can customize the maximum and minimum values for automatic brightness adjustment (right).

It comes with a long, five-year warranty. Five years from now when the warranty period is up, a 4K display will still be usable and will not be obsolete.

It"s not that difficult to connect PCs to a 4K display. If your PC has an HDMI port that supports HDMI 1.4 or later, 4K display is possible at a refresh rate of 30Hz.

However, if you want a refresh rate of 60 Hz (4K@60Hz), there are some limitations. A major precondition is that the interface is DisplayPort 1.2 or later. 4K@60 Hz display requires a very large transmission bandwidth of 16 Gbps. Neither DVI (including DualLink) nor HDMI 1.4 is capable of this kind of bandwidth.

The HDMI 2.0 Level B standard is capable of transmitting 4K 60 Hz signals over the HDMI 1.4 transmission bandwidth, but the color depth is YUV 4:2:0, and colors blur, so it is not suited to displays. So you"ll have to wait for HDMI 2.0 LEVEL A to transmit 4K 60 Hz signals over HDMI. For that reason, DisplayPort 1.2 is currently the only means of achieving 4K 60 Hz display.

As for other limitations on 4K 60 Hz display besides the interface, they vary depending on the display, but there are basically no problems when it comes to the FlexScan EV3237. This is because SST (Single Stream Transport) is the method of 4K 60 Hz transmission used by the FlexScan EV3237 via DisplayPort, and it is capable of 4K display without any special settings. However, there are some graphics cards that support DisplayPort 1.2 but do not support SST, so it would be a good idea to check at the time of purchase just in case.

Some products from other companies use DisplayPort"s MST (Multi-Stream Transport) as the method of transmission and this creates some limitations. With the MST method, the 4K signal is split in two (two 1920 x 2160 pixel screens), so the graphics driver"s extension function (such as AMD"s EyeFinity) has to be used to combine them into a single screen.

However, whether so much emphasis needs to be placed right now on 4K 60 Hz display is open to question. It requires quite a large amount of power to playback 4K videos at 60 Hz, and there still are not many 4K 60 Hz video sources out there. For game use, performance on the PC side is unlikely to keep up. Still, daily operations like cursor movement and scrolling are smoother at 60 Hz than at 30Hz. There are no particular problems with 30 Hz display, but thinking about the future, a product compatible with 4K 60 Hz display will provide greater peace of mind.

As explained above, EIZO"s FlexScan EV3237 has a pixel pitch that strikes a good balance between 4K high definition display and a large work space on a 31.5" wide screen, so it meets both needs. It has the perfect screen size for enjoying the high 4K resolution on a PC.

Recently there have been some 4K displays coming out that use TN panels with a narrow viewing angle to provide a lower price, but the FlexScan EV3237 uses an IPS panel with a wide viewing angle to minimize contrast and color changes at different angles. Of course, it"s chock full of EIZO"s proprietary technology for better picture and relief of eye fatigue, so the basic performance as an LCD is high even without the 4K display and large screen.

The FlexScan EV3237 is a high-end model, which is good news for those users that prioritize quality and usability. It"s a high-quality device that comes with all the elements currently required of a 4K display.

In addition to the large screen and high definition, it also has high-quality display, featuring an IPS panel with a wide viewing angle and offering smooth gradation with 10-bit gamma correction. The spectrum is equivalent to sRGB.
