tft display special requirements made in china

For many years, TFT displays have been the dominating technology in visualization. TFT LCDs are all around in our daily lives — in consumer and automotive applications, in our business environments, in healthcare, and within communication devices, home appliances, and factory automation products. While there are many LCD products available today, they’re not all suitable for every application. This is especially the case for industrial LCD monitors. To determine the best LCD display for your application, it’s important to understand your target market and its unique design issues.

The vast majority of LCD displays are designed for consumer devices such as smartphones, cameras, tablet computers, and gaming devices. But they have very different requirements than those for industrial applications. Due to very competitive pricing and quick production cycles, consumer display modules don’t always incorporate the durability, reliability, and advanced features required to survive in an industrial environment. Product life cycles are also typically much shorter in consumer applications. Screens manufactured for these applications are generally only available for one, in best case two years.

In contrast, display modules for industrial applications require Long product life cycles— often up to ten years or more. Plus, when an industrial module is discontinued by the manufacturer, a successor product should be backward-compatible so as to fit into the existing enclosure without requiring a redesign of the entire system.

The ability to withstand temperature variations as well as shock and vibration is also a key consideration when selecting displays for today’s industrial applications. They must be resilient enough to withstand frequent bumps or jiggles by machine operators and surrounding equipment, and also must be able to handle various operating temperatures.

Industrial displays are typically housed in an enclosure as part of a larger piece of equipment. In these situations, the heat generated by the surrounding equipment gets trapped within the enclosure, which can be detrimental to many displays. Therefore, it’s important to keep the real storage and operating temperature requirements in mind when choosing a display. While measures can be taken to dissipate the generated heat — such as using fans within the enclosure — the most efficient way to ensure compliance with the storage and operating temperature requirements is to select a display that is optimized for these types of environments. Fortunately, improvements in liquid-crystal materials have made it possible to extend the operating temperature ranges of LCDs from –30 to 80°C presently.

It’s important that displays used in industrial applications support clear and precise viewing from multiple angles under a variety of ambient light conditions. The brighter the environment, the more difficult it can be to read a standard transmissive LCD display with a typical brightness of 250 to 300 cd/m2. NVD has developed displays that can perform in the 800-cd/m2-and-higher range by implementing high-efficiency LEDs for the backlight unit– if necessary, in combination with special brightness enhancement films.

Increasing the display’s contrast ratio is another effective way that display manufacturers can improve display readability in bright environments. Typical contrast ratios for non-industrial displays are in the range of 200:1 to 300:1, which may not be sufficient when a machine operator is viewing the display from a distance. Displays with contrast ratios around 500:1 or greater are better suited for industrial environments. Another benefit of this method is that it doesn’t increase power consumption.

Multi-angle readability is another key selection factor. In a typical industrial environment, a machine operator is more likely to be positioned at an off-angle rather than right in front of the screen. Implementing a display designed for consumer applications typically doesn’t work well in this situation, as there is image distortion and color shifting when viewed at an angle. But, a number of technologies have been employed to improve off-angle viewing in displays, making them suitable for industrial applications. Some film-based technologies yield viewing angles of 160º horizontally and 140º vertically, but in some cases, this is still not sufficient. In-plane switching technology (IPS), multi-domain vertical alignment (MVA), and fringe field switching (FFS)offer alternatives. These proprietary technologies are able to achieve viewing angles of almost 90-degrees into all four directions without any color shift.

Size and resolution also play a role in overall readability. Displays between 2 and 15-inch diagonal sizes are used most often in industrial applications. These sizes provide sufficient area to view figures, waveforms, and other graphical data without taking up too much real estate on a piece of equipment.

From an aspect ratio 4:3 initially, industrial displays are now shifting to wide formats with WVGA to WXGA resolutions. The wide-aspect format enables users to view longer waveforms and more data on a single display. These display modules can also be designed to incorporate touch-key functions, allowing equipment manufacturers to skip physical switches and buttons and design HMIs based more on software than hardware.

The liquid crystal display (LCD) technology has been used in several electronic products over the years. There are more reasons for LCDs to be more endearing than CRTs.

In ruling NY N320557 (August 4, 2021), Customs and Border Protection (CBP) discussed the country of origin of five Thin Film Transistor – Liquid Crystal Display (TFT-LCD) modules. All five modules are virtually identical in composition, as they are all composed of a TFT-LCD cell, polarizers, a backlight, a driver and control printed circuit board (PCB), and a flexible PCB for connection. TFT display technology allows for the construction of high-resolution LCD displays, and the modules – once completed – can be incorporated into a variety of consumers display applications.

The manufacturing process for the five modules is also identical. The process begins in Japan where the TFT-LCD cell is manufactured. The TFT is created by depositing transistors onto a substrate through chemical vapor deposition, while the color filter is manufactured by building a color matrix on a glass substrate. The creation process of the cells is then completed when a layer of liquid crystal is deposited between the color filter and TFT as the two part are bonded together, creating a sheet of TFT-LCD cells. As next steps, the sheet of cells is delivered to China to be cut into individual cells. The cut-up cells are then bonded to the printed circuit board assembly (PCBA) – which contains the driver and control circuity – before the polarizers, backlight, and flexible connection PCBA are attached.

CBP also established that “substantial transformation” takes place when a particular product “emerges from a process with a new name, character or use different from that possessed by the article prior to processing.” The agency explained that the completed TFT-LCD cell is what imparts the essential function of the module and that the manufacturing process in Japan is what renders the end-use of the product. Despite the assembly that took place in China, the process did not substantially transform the cell into a new and different article. As such, CBP determined that the country of origin of the five modules is Japan.

The reason for LCD Display flashing screen: shielding coil; Signal interference; Hardware; Refresh frequency setting; Monitor time is too long; Too high...

There are more and more TFT displays used in outdoor applications, such as automobile display, digital signage and kiosks. High ambient light in outdoor environment often causes wash-out image and renders the screen not readable. Readability & sustainability of TFT  display under direct sunlight is becoming vital. Topway Display has been developing sunlight readable LCD display solution for years. The company understands the ins and outs of sunlight readable TFT LCD.

For an LCD to be readable in outdoor environment with very bright ambient light, the LCD screen’s brightness needs to exceed the intensity of light that is reflected from the display surface. To be comfortably viewed by human eyes, the LCD’s brightness needs to exceed its reflected light by a factor of 2.5 at minimum. Naturally, to make an LCD sunlight readable, we can work on two areas, increasing brightness or reducing reflectance.

On a clear day in direct sunlight, the ambient brightness is about 6000 cd/m2. And a typical TFT LCD with touch screen reflects about 14% of ambient light, which is around 840 cd/m2. These days, most LCD displays use LED backlight as light source. It is not too difficult to increase an LCD’s brightness to 800 ~ 1000 Nits, to overpower the bright reflected sunlight. Thus, you have a sunlight readable TFT LCD.

However, this method requires more backlight LEDs and/or higher driving current. The drawbacks are high power consumption, more heat dissipation, increased product size and shorter LED backlight lifespan. Apparently, increasing backlight to make TFT LCD sunlight-readable is not a very good solution.

Transflective TFT LCD is a TFT LCD with both transmissive and reflective characteristics. A partially reflective mirror layer is added between LCD and backlight. This change turns part of the reflected ambient light into LCD’s light source, increasing the TFT display’s brightness. However, transflective TFT LCD is more expensive than transmissive one. At the same time, the partially reflective mirror layer will block some of the backlight, making it not ideal in indoor or low ambient light environment.

The total reflectance on a TFT LCD with touch panel is the sum of reflected light on any interface where two materials meet. As an example, between polarizer and display glass, the difference in index of refractions for the two materials is very small, around 0.1. So the reflected light on this interface is only 0.1%. As Fresnel’s equation points out, we should focus reflection reduction on air interfaces. For air, its index of refraction is 1; for glass, it is 1.5. And that results in a reflectance of 4.5%. Therefore, the three air interfaces contribute majority of TFT LCD’s reflectance, at about 13%.

For food industry application, shattered glass is a serious problem. An LCD screen with external film solves this issue nicely. As for automotive applications, in an accident, broken LCD with top AR film won’t produce sharp edge glass that could harms auto occupant. Nevertheless, a top film always reduces TFT LCD’s surface hardness. And it is susceptible to scratches. On the other hand, AR coating retains LCD’s hardness and touch performance. But it comes with a bigger price tag.

Another quick and easy way to tackle reflectance is to affix a linear polarizer on the top of TFT screen. When ambient light gets to the top polarizer, only half of the light passes through. Which results in reflection light cutting to half. This is a very low cost way to increase TFT LCD’s contrast, such that making it more sunlight readable.

Laminating a circular polarizer in TFT LCD will get rid of a lot of reflectance. That is because when ambient light passes through circular polarizer it gets circularly polarized. And when it is reflected, the polarization direction flips by 180 degrees. So when reflected light comes back to the circular polarizer, nothing goes through to viewer’s eyes.

This method is very effective for an LCD display with resistive touch panel. We know resistive touch LCD has two air gaps: air gap between two ITO layers and air gap between touch panel and LCD display. Reflectance caused by the two air gaps is very high. Applying circular polarizer blocks off most of the reflected light, and makes the LCD display sunlight readable.

The disadvantage of such solution is its cost. Since we need not only a circular polarizer, but also a retarder film on the top of LCD display, making sure light originates from within LCD is not blocked by external circular polarizer.

Add AR films on both interfaces of internal air gap. The add-ons can reduce this area’s reflection from 8.5% to 2%. And since the AR films are not outside facing, they are much cheaper than the one used outside. Keeping the air gap also retains the ease of service, in case either touch panel or LCD display needs to be repaired.

The most effective way is to eliminate air gap totally, by using optical bonding. In plain language, we fill air gap with special optical adhesive, to smooth out the area’s refraction index differences. Such that reflectance caused by internal air gap drops from 8.5% to 0.5%. Optical bonding is expensive but effective way to improve TFT LCD sunlight readability. It enhances durability and resistance to impact. Moreover, no air gap means no moisture condensation and fogging.

There are many ways to make TFT LCDsunlight readable. They all have their own pros and cons. With 20+ years" LCD design and manufacturing experience, Topway knows how to create the best sunlight readable TFT LCD for challenging environments. Leave us a message and let"s start the conversation of creating suitable sunlight readable TFT LCD for your project.

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 liquid crystal displays used in calculators and other devices with similarly simple displays have direct-driven image elements, and therefore a voltage can be easily applied across just one segment of these types of displays without interfering with the other segments. This would be impractical for a large display, because it would have a large number of (color) picture elements (pixels), and thus it would require millions of connections, both top and bottom for each one of the three colors (red, green and blue) of every pixel. To avoid this issue, the pixels are addressed in rows and columns, reducing the connection count from millions down to thousands. The column and row wires attach to transistor switches, one for each pixel. The one-way current passing characteristic of the transistor prevents the charge that is being applied to each pixel from being drained between refreshes to a display"s image. Each pixel is a small capacitor with a layer of insulating liquid crystal sandwiched between transparent conductive ITO layers.

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.

Polycrystalline silicon is sometimes used in displays requiring higher TFT performance. Examples include small high-resolution displays such as those found in projectors or viewfinders. Amorphous silicon-based TFTs are by far the most common, due to their lower production cost, whereas polycrystalline silicon TFTs are more costly and much more difficult to produce.

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.

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.

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.

TFT dual-transistor pixel or cell technology is a reflective-display technology for use in very-low-power-consumption applications such as electronic shelf labels (ESL), digital watches, or metering. DTP involves adding a secondary transistor gate in the single TFT cell to maintain the display of a pixel during a period of 1s without loss of image or without degrading the TFT transistors over time. By slowing the refresh rate of the standard frequency from 60 Hz to 1 Hz, DTP claims to increase the power efficiency by multiple orders of magnitude.

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.

TFT display module is a Thin Film Transistor, and AMOLED is Active-matrix organic light-emitting Display. The TFT display module is backlight-on the liquid crystal panel; AMOLED is a panel that emits light on its own; TFT display module structure is more thick and strong, AMOLED is very thin and also weak, TFT display module is used widely than AMOLED, AMOLED is used in consumer products the most, like a smartwatch, mobile phone, and TV.

IPS is In-Plane Switching, It is also known as free viewing angle, which means the viewing angle of the display on 4 sides is the same, a normal display has its best viewing angle like 6 o’clock or 12 o’clock. While the TFT display module contains normal viewing angles and IPS display,IPS display is a kind of TFT display module.

TFT display module belongs to LCD, LCD is Liquid Crystal Display, it contains mono(single color) LCD and color LCD, single color LCD is barely used now, and color LCD has STN and TFT two types. Therefore, TFT display module is a kind of LCD display.

OLED is Organic Light Emitting Display, it is a display that emits light on its own, and it does not need an extra backlight, so it requests lower power consumption than TFT display module but its lifetime is shorter than TFT(5000 hours), AMOLED is a kind of OLED but it is more colorful. TFT display module requests a backlight to light on and power consumption are higher than OLED, but its lifetime is much longer(20000 hours).

The LED display is working by lighting up the LED lights, the TFT display module is lighted up by the backlight and the liquid crystal starts to work and shows contents. TFT display module has brighter and more true color, and lower price and LED display has lower power consumption, smaller heat, and longer lifetime.

Compares to other types of display, TFT display module is the more widely used, it can be made in different shapes and sizes, from very small sizes to big sizes. The resolution now is higher and higher, and the price of custom TFT display modules is more and more competitive. Its lifetime is longer than the OLED display, and its color is brighter than OLED.

This is in reply to your letter dated August 15, 2002, on behalf of Hitachi Electronic Devices (USA), Inc. (Hitachi) concerning the country of origin of a device that will result from manufacturing operations in China. You seek a ruling that the device, a Thin Film Transistor (TFT) Liquid Crystal Display (LCD) module will be considered a product of China for the purposes of country of origin marking under Section 304 of the Tariff Act of 1930, as amended (19 U.S.C. §1304).

The Hitachi TFT LCD module that is the subject of this ruling is used to display the image on cellular telephones, digital cameras, car navigation systems and other devices.

All parts and materials used in the China manufacturing operations are of Japanese origin. These parts and materials consist of: The TFT LCD No Cutting Cell; the Flexible Printed Circuit; and module parts. The module parts include: liquid crystal agent, epoxy acrylic resin, upper and lower side polarizers, integrated circuit chips, epoxy film, light guide unit, plastic mold, and tapes and resins. There are two main aspects of the Chinese manufacturing operations: 1) production of the TFT LCD Cell from the TFT LCD No Cutting Cell; and 2) assembly of the TFT LCD Module.

Production of the TFT LCD Cell from the No Cutting Cell consists of breaking and cutting the prepared materials into 32 pieces, filling the cells with liquid crystal agent under vacuum conditions, drying and hardening, sealing the filling entrance, and rounding sharp edges, washing and quality inspection.

The TFT LCD Cell is the component that forms the basis of the module. First the cell is covered with a polarizer on both sides. Then the Flexible Printed Circuit is attached at the edge. Then a light guide unit and cover sheet are attached. Finally, the unit is encased in a plastic mold and sealed with adhesive.

You submit that the operations described here concern a product that is identical except for size to a product that was reviewed by this office in Headquarters Ruling Letter (HQ) 562385 (May 14, 2002). In that ruling it was concluded that the production of a TFT LCD module for notebook and desktop computers effected substantial transformation of the individual components, and that the production operations resulted in a product of China. It is urged that the same conclusion is appropriate for the instant operations.

Do the manufacturing operations in China result in substantial transformation of the materials from Japan such that the completed TFT LCD module may be marked as a product of China?

Based on the facts provided, it is our opinion that the assembly of the various components used in producing the TFT/LCD module in China, effects a substantial transformation of the individual components. The numerous individual components, which are made in Japan, lose their identity and become integral part of the new article – TFT/LCD module. The assembly operations are also not minimal or simple. Thus, the TFT/LCD module as imported into the United States qualifies as a product of China and therefore should be marked as such. This office is in agreement with you that the conclusion reached in HQ 562385 is applicable to the production operations described herein.

Also, you have asked whether the TFT-LCD modules may be marked “Made in China” or Assembled in China from foreign (Japanese) components”. Either of these markings would be acceptable. “Assembled in…from components of…” is specifically approved under 19 CFR 134.43(e).HOLDING:

The operations described in the submission result in substantial transformation such that the TFT-LCD module is considered to be a product of China for the purposes of country of origin marking under Section 304 of the Tariff Act of 1930, as amended. The marking indications proposed are acceptable.
