full active lcd displays manufacturer

TFT is an LCD Technology which adds a thin-film transistor at each pixel to supply common voltages to all elements. This voltage improves video content frame rates. Displays are predominantly utilizing color filter layers and white LED backlighting.

OLED Displays are emissive displays and do not utilize liquid crystal. Each pixel is emissive with light. Passive OLED displays multiplex power and logic through the IC. Active OLED displays add a transistor at each pixel to supply power directly to the pixels and the IC only performs logical functions.

Japan Display Inc. (JDI) has announced its development of a new display technology known as a “Full Active” panel. The new design boasts that it can reduce the width of the bottom bezel down to as narrow as the other three sides, potentially reducing the size of smartphones using this display type. To coincide with the announcement, the company also introduced a 5.5-inch 1080p LCD display for smartphones built on this technology.

The “Full Active” name seems to be a bit of misnomer though. The display technology still appears to operate using the traditional LCD active-matrix method of controlling individual pixels using capacitors and transistors.

Instead, JDI says that it has managed to decrease the bezel requirements for its new display by adopting a new high-density wiring layout, along with new processing and module assembly technologies. Essentially, the company has managed to pack extra wiring into the display itself, which reduces the extra space usually required at the bottom of the LCD.

Planar displays are usually front and center, dutifully delivering the visual experiences and critical information customers need, with proven technology that is built to withstand the rigors of constant use.

This is another story just like those, except this one involves the very screen you’re probably looking at, especially if it’s based on LCD technology.

In the 1970s, a pair of engineers that worked for Westinghouse, T. Peter Brody and Fang-Chen Luo, came to develop the first active-matrix LCD screen. Brody, born in Hungary, had gained an interest in the fledgling technology of thin film transistors, an experimental technology that had come to be seen as a potential avenue for visually displaying content in a more compact form than a cathode-ray tube.

“It has been apparent for some time that a solid-state flat panel display is conceptually achievable,” the patent filing stated. “Efforts to utilize silicon technology to this end are limited by the size limitation problems of the silicon wafer, which negates achievement of large area displays.”

But it was the starting point of the technology that stuck. By the mid-1990s, active-matrix displays that relied on color became the norm in laptops, thanks to their combination of vivid color and thinness. But despite the concept coming from an American company’s R&D department and improved by other American R&D departments, nearly all panels were developed by Japanese manufacturers even at the beginning of their mainstream use cases.

In fact, Westinghouse’s efforts with the flat-panel LCD display ended way back in the 1970s, as did similar efforts at other large U.S. companies. “Both large corporations and venture capital-backed start-ups have quit the field, usually after hitting production difficulties,” authors Richard Florida and David Browdy wrote.

From their discovery in 1888 to their first application within displays in the 1960s, liquid crystals have become a mainstream material choice with many impactful applications in the world of electronics.

As the key component behind liquid crystal displays (LCD), these materials change light polarization to create vibrant, high-resolution images on digital screens. The growth of LCD technology has helped propel the larger display panel market enormously, with industry valuation projected to reach $178.20 billion by 2026.

A prolific variety of LCD types has been developed to best meet their exact use-cases and end-environments. Displays may be optimized for power consumption, contrast ratio, color reproduction, optimal viewing angle, temperature range, cost, and more.

Passive Matrix LCDs are addressed with common and segment electrodes. A pixel or an icon is formed at the intersection where a common and a segment electrode overlap. Common electrodes are addressed one-at-a-time in a sequence. Segment electrodes are addressed simultaneously with the information corresponding to all pixels or icons connected to the current common electrode. This method is referred to as multiplexing.

Passive Matrix LCDs offer a cost advantage (both parts and tooling) and are highly customizable. The counterpart to Passive Matrix displays are Active Matrix displays.

Active-Matrix LCDs were developed to overcome some of the limitations of Passive Matrix LCDs – namely resolution, color, and size. Within an Active-Matrix LCD, an “active element” is added to each pixel location (the intersection between a horizontal row and vertical column electrode). These active elements, which can be diodes or transistors, create a threshold and allow control of the optical response of the liquid crystal structure to the applied voltage. Transistors are used as switches to charge a capacitor, which then provides the voltage to the pixel. Whenever a row is turned on, one at a time, all transistor switches in that row are closed and all pixel capacitors are charged with the appropriate voltage. The capacitor then keeps the voltage applied to the pixel after the row is switched off until the next refresh cycle.

Furthermore, the processes used for manufacturing Active-Matrix LCDs can create much finer details on the electrode structure. This allows splitting each pixel in three sub-pixels with different color. This together with the better voltage control allows full color displays.

The transistor switches used in Active Matrix Displays must not protrude significantly above the surface of the display substrates lest they might interfere with a uniform liquid crystal layer thickness. They must be implemented in thin films of suitable materials. Hence, the name Thin Film Transistors (TFT). While AM and TFT have a different meaning, they are often used interchangeably to indicate a higher performance display.

Currently the most common Electronics Display Technology on the market is LCD technology and among LCD technologies, TFT display technology is the most widely used across consumer applications (laptops, tablets, TVs, Mobile phones, etc.) as well as many industrial, automotive, and medical applications.

As the first commercially successful LCD technology, Passive Matrix Twisted Nematic (TN) LCDs use a 90° twist of the nematic LC fluid between two polarizers to display information. The twist of the LC fluid either blocks light from passing through the LCD cell or allows light to pass, depending on the applied voltage. The applied voltage changes the twisted nematic orientation into an orientation that does not change the polarization of tight. This is called the TN effect.

TN displays can be normally white (NW) when they use two orthogonal liner polarizers or normally black (NB) when parallel linear polarizers are used. ‘Normally’ refers to what happens when no voltage is applied.

Initially, Passive TN LCDs were used in segmented, icon, or character displays where an image element was turned “on” and “off” depending on how the fluid was driven. Improvements were made along the way to address the limited viewing angle of TN technology, which can suffer from contrast loss or even inversion at shallow angles.

It can be advantageous to twist the director of the nematic phase a bit more than 90 degrees, but less than 180 degrees. Displays like this are a subset of TN displays and are sometimes caller Hyper Twisted Nematic Displays.

The numbers of rows or icons that can be addressed in a TN display without Active Matrix addressing is very limited. This is related to how strongly the liquid crystal responds to the applied voltage. Twisting the LC nematic fluid more than 180 degrees (typically between 210 and 270 degrees) causes the display to require a much smaller voltage difference between on and off pixels. This in turn allows addressing of many more rows without an active matrix. Displays with a twist between 210 and 270 degrees are called Super Twisted Nematic displays.

The higher display resolution of STN displays comes at a price. The optical effect is no longer neutrally black and white as in a TN display. Rather these displays are naturally yellow and black or blue and white. The color can be somewhat compensated with colored polarizers, but that comes at the expense of brightness and contrast.

The color in STN displays is caused by birefringence. Adding the same birefringence in the opposite direction can compensate for the effect. Initially this was done by stacking two STN displays on top of each other. This is referred to as Double STN or DSTN, but this is of course thicker and more expensive.

The birefringence of an STN display can be approximated with a stretched transparent plastic film. Adding such a film to an STN display instead of the 2nd STN display is a lot more attractive and has almost the same performance. This is referred to as a Film Compensated STN display (FSTN, or sometimes if two films are used as FFSTN).

FSTN displays are used commonly in consumer, medical and industrial display applications that require low cost and do not need high resolution images or full color.

Another development to the TN display was to use the same concept as in FSTN displays on TN displays. However, the film cannot just be a stretched polymer. Instead, a twisted liquid crystal structure is made and polymerized into a film that is used as a compensation film for TN displays. As this method mostly improves the display characteristics at shallow viewing angles while preserving the excellent performance in straight on viewing, this technology is called Wide View Twisted Nematic (WVTN).

The above display technologies have liquid crystal molecules that are aligned nearly parallel to the display surface with more or less twisting when going from one substrate to the other. In VA (also called VAN) displays, the liquid crystal molecules are aligned vertically with respect to the display surface. Applying a voltage causes the molecules to lay flat, with or without twist.

The advantage of this arrangement is a very dark black state with very little light leakage. This allows making displays with a black mask and colored icons or symbols. These displays look like color displays with brilliant colors, however each image element or icon can only have its assigned color or black.

Due to the ability in AM displays to address one row while the other rows are isolated, the demands on the electro-optical performance of the Liquid Crystal Configuration are less stringent. In principle, all the above mentioned configurations can be used in AM displays. In practice, TN, and WVTN are frequently used as well as some versions of VA technology described below. (MVA, AIFF-MVA, PVA, ASV).

The advantage of these technologies is a much wider and more symmetrical viewing angle along with the elimination of the contrast inversion (or color shift) seen in TN TFT LCDs when viewed from various angles. IPS and FFS displays also are less sensitive to pressure, which is a big advantage in touchscreen displays.

Here, each color sub-pixel is further divided into zones (called domains) having a different direction of the molecular movement when voltage is applied. Again, the purpose is a much wider and more symmetric viewing performance and the elimination of color shifts and contrast inversion at shallow angles. MVA technology achieves that with carefully designed protrusions on the inside surfaces of the display, while PVA uses fine patterning of the electrodes on both substrates.

The integrated circuit is a patterned piece of silicon or other type of semiconducting material. A modern IC contains millions or even billions of tiny transistors. Their tiny size allows for the fabrication of smaller, faster, more efficient, and less expensive electronic circuits. The driver chips addressing electronics displays are ICs.

Legacy LCDs normally have the driver ICs (integrated circuit) mounted on a printed circuit board (PCBA) which consists of a flat sheet of insulating material used to mount and connect the driver IC and electronic periphery to the LCD. PCBs can be a single-sided, double-sided or multi-layer.

Low Voltage Differential Signaling (LVDS) is an interface to the display, not a display technology itself. This technology is not specific to displays, as it’s used in many other applications as well. It’s a high-speed signal that provides some noise immunity for the display. It also allows for longer distances compared to parallel interfaces.

To create an LCD, you take two pieces ofpolarized glass. A special polymer that creates microscopic grooves in the surface is rubbed on the side of the glass that does not have the polarizing film on it. The grooves must be in the same direction as the polarizing film. You then add a coating of nematic liquid crystals to one of the filters. The grooves will cause the first layer of molecules to align with the filter"s orientation. Then add the second piece of glass with the polarizing film at a right angle to the first piece. Each successive layer of TN molecules will gradually twist until the uppermost layer is at a 90-degree angle to the bottom, matching the polarized glass filters.

If we apply an electric charge to liquid crystal molecules, they untwist. When they straighten out, they change the angle of the light passing through them so that it no longer matches the angle of the top polarizing filter. Consequently, no light can pass through that area of the LCD, which makes that area darker than the surrounding areas.

Building a simple LCD is easier than you think. Your start with the sandwich of glass and liquid crystals described above and add two transparent electrodes to it. For example, imagine that you want to create the simplest possible LCD with just a single rectangular electrode on it. The layers would look like this:

The LCD needed to do this job is very basic. It has a mirror (A) in back, which makes it reflective. Then, we add a piece of glass (B) with a polarizing film on the bottom side, and a common electrode plane (C) made of indium-tin oxide on top. A common electrode plane covers the entire area of the LCD. Above that is the layer of liquid crystal substance (D). Next comes another piece of glass (E) with an electrode in the shape of the rectangle on the bottom and, on top, another polarizing film (F), at a right angle to the first one.

The electrode is hooked up to a power source like a battery. When there is no current, light entering through the front of the LCD will simply hit the mirror and bounce right back out. But when the battery supplies current to the electrodes, the liquid crystals between the common-plane electrode and the electrode shaped like a rectangle untwist and block the light in that region from passing through. That makes the LCD show the rectangle as a black area.

There are, however, a number of European companies with the technical capabilities to produce LCDs and to compete worldwide, provided that production investments are made on an appropriate scale for a well-defined technology.

The approach, which is now widely recognised as the most promising, is to deposit a matrix of switching transistors on an inner wall of the LCD (AMLCD). Three of the partners have demonstrated their technical know-how in the field of active matrix panels by the realisation, at the laboratory level, of displays with viewing areas of approximately 10 x 10 cm{2} and resolution up to 256 x 256 pixels (see project 833).

Although applications for such displays are expected in small portable equipment and video projectors, it seems necessary to develop larger (A4) high-resolution panels to meet the key requirements of office terminals. The main goal of the project is therefore to validate technologies for the production of active matrix LCDs up to A4 in size.

There are a number of European companies with the technical capabilities to produce liquid crystal displays (LCD) and to compete worldwide, provided that production investments are made on an appropriate scale for a well defined technology. Such a display, compact and operating at low voltage, must be able to show colour and grey scale with high resolution and should be less bulky than current cathode ray tube (CRT) devices in orderto fulfil office systems requirements in the near future.

The main goal of the project is therefore to validate technologies for the production of active matrix LCD up to A4 in size. The work involves the preparation of direct view flat panel displays using amorphous silicon wilth external integrated circuit (IC) drivers in the short term, or using polycrystalline silicon with integrated drivers as an alternative in the longer term. During the first 3 years of the project the realization of an A4 amorphous silicon matrix will be carried out, and, in parallel, a polycrystalline silicon process with integrated drivers and A4 glass compatibility, including A4 specific equipment, will be developed (6 inch diagonal demonstrator).

A complete new facility dedicated to the realization of 14 inch x 14 inch substrate displays has been built near Grenoble, and is already experiencing problems arising form amorphous silicon display production in a pilot line. A5 8-colour displays have been demonstrated as a first step towards the final goal. The processing of the panels is on course. The consortium recently demonstrated a 2.8 inch diagonal active matrix LCD display with fully integrated polysilicon row and column drivers. The device contains a 200 x 200 pixel array, and can be driven through a 28-pin connector.

The work involved the preparation of direct-view flat-panel displays using amorphous silicon with external IC drivers in the short term, or using polycrystalline silicon with integrated drivers as an alternative in the longer term.
