As one of the most professional tablet TFT LCD display manufacturers and suppliers in China, we"re featured by quality products and good service. Please rest assured to wholesale custom made tablet TFT LCD display at competitive price from our factory. Tablet TFT LCD Display, 7 Inch TFT Screen, 8 LCD Display

This module has a 10.1 inch diagonally measured active area with WUXGA resolutions (1200 horizontal by 1920 vertical pixel array) with portrait display. Each pixel is divided into RED, GREEN, BLUE dots which are arranged in vertical stripe and this module can display 16.7M colors. The 10.1” TFT LCD panel used for this TFT module is adapted for a low reflection and higher color type display. Mainly used for smart home with rotate display ability and tablet device with compact design.

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.

New Vision Display’s experts are prepared to assist in defining appropriate solutions for all applications and in helping find the right balance between manufacturing cost and performance.

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.

If you want to buy a new monitor, you might wonder what kind of display technologies I should choose. In today’s market, there are two main types of computer monitors: TFT LCD monitors & IPS monitors.

The word TFT means Thin Film Transistor. It is the technology that is used in LCD displays.  We have additional resources if you would like to learn more about what is a TFT Display. This type of LCDs is also categorically referred to as an active-matrix LCD.

These LCDs can hold back some pixels while using other pixels so the LCD screen will be using a very minimum amount of energy to function (to modify the liquid crystal molecules between two electrodes). TFT LCDs have capacitors and transistors. These two elements play a key part in ensuring that the TFT display monitor functions by using a very small amount of energy while still generating vibrant, consistent images.

Industry nomenclature: TFT LCD panels or TFT screens can also be referred to as TN (Twisted Nematic) Type TFT displays or TN panels, or TN screen technology.

IPS (in-plane-switching) technology is like an improvement on the traditional TFT LCD display module in the sense that it has the same basic structure, but has more enhanced features and more widespread usability.

Both TFT display and IPS display are active-matrix displays, neither can’t emit light on their own like OLED displays and have to be used with a back-light of white bright light to generate the picture. Newer panels utilize LED backlight (light-emitting diodes) to generate their light hence utilizing less power and requiring less depth by design. Neither TFT display nor IPS display can produce color, there is a layer of RGB (red, green, blue) color filter in each LCD pixels to produce the color consumers see. If you use a magnifier to inspect your monitor, you will see RGB color in each pixel. With an on/off switch and different level of brightness RGB, we can get many colors.

Winner. IPS TFT screens have around 0.3 milliseconds response time while TN TFT screens responds around 10 milliseconds which makes the latter unsuitable for gaming

Winner. the images that IPS displays create are much more pristine and original than that of the TFT screen. IPS displays do this by making the pixels function in a parallel way. Because of such placing, the pixels can reflect light in a better way, and because of that, you get a better image within the display.

As the display screen made with IPS technology is mostly wide-set, it ensures that the aspect ratio of the screen would be wider. This ensures better visibility and a more realistic viewing experience with a stable effect.

Winner. While the TFT LCD has around 15% more power consumption vs IPS LCD, IPS has a lower transmittance which forces IPS displays to consume more power via backlights. TFT LCD helps battery life.

Normally, high-end products, such as Apple Mac computer monitors and Samsung mobile phones, generally use IPS panels. Some high-end TV and mobile phones even use AMOLED (Active Matrix Organic Light Emitting Diodes) displays. This cutting edge technology provides even better color reproduction, clear image quality, better color gamut, less power consumption when compared to LCD technology.

This kind of touch technology was first introduced by Steve Jobs in the first-generation iPhone. Of course, a TFT LCD display can always meet the basic needs at the most efficient price. An IPS display can make your monitor standing out.

Welcome at Riverdi University. In this lecture we’ll talk about different kinds of glass in TFT LCD displays and surfaces that we use to protect displays, or we can use to protect with the glass the entire devices

We will talk about different types of glass in TFT LCD displays, then the surface treatments, what we do to achieve different parameters of glass surfaces, about the hardness – important when we want to protect something, then about painting the glass, how we do it and what we can achieve, IK rate, how much mechanical impact we can place on the glass, and will it withstand this still and at the end about laminated glass, why we laminate glass and what we can achieve by doing that.

The most important thing with the glass in TFT LCD displays is to protect the display, but not only. As you can see on the pictures above, glass is an element of the design of the devices. It makes devices look better and can be designed in a way that protects not only the display, but the entire surface of a device, like for example for the coffee machine on the picture above, where we have a display with some additional graphic that covers the whole front of the device. Glass is one of the best materials that we use in electronics to protect screens, because it is very hard and it is hard to scratch. It is mechanically strong, cheap, and exceptionally good in optics. For glass, the transparency rate is typically more than 90% or even 95% percent. It is widely available, we know a lot of techniques how to manufacture it and how to prepare it for some special advanced designs as we can change the shape of glass quite easily nowadays.

Now we will talk about types of glass that we use to protect screens and devices. Mainly we use two types of glass in TFT LCD displays, one is chemically strengthened glass, that we call CS type glass, the other is thermally tempered glass, hardened glass where we use hot temperature to make it stronger. For our standard products we typically use on the touch screens chemically strengthened glass. Our standard thickness is 1.1-millimeter thickness. This kind of glass is pretty strong, comparing to the regular glass. Chemical strengthening means that we treat the surface with ions, usually silver ions. We increase the strength of the surface of the glass because glass usually breaks when the surface breaks. We do not change the glass internally with chemical strengthening, we just change the surface hardness, and it is enough to make the glass much stronger.

Another property or type of glass that we will talk about is Optiwhite and Float. Float is the most common glass that we use in architecture designs, but also in many touchscreens. The float glass is the most common, most popular and the cheapest, but sometimes we have specific requirements. We sometimes need to have very good color reproduction, especially light colors, white color. Then we use glass called Optiwhite. To achieve that we need to remove the iron from the glass. Float glass has a little bit of iron which makes it green or greenish. If we look straight through the glass, we may not see that but if we look like from an angle, we can see the green color. If we put a white background, we will also see this greenish color a little bit. So, if there are specific requirements, we use Optiwhite, it is especially worth considering if you have a white background. Usually, the Optiwhite is a little bit more expensive, so it is worth checking with the manufacturer of the display what we can use in our case.

Now let us talk about hardness of glass in TFT LCD displays. Of course, to talk about hardness we need to measure it. For that we have the Mohs scale where we have 11 different levels of hardness. Like you see on the picture above, the 10th  is diamond and the 1st  is talk. What we normally use is glass with hardness between 5 and 7. In some cases we also use Gorilla glass with hardness 9. It is used on our phones or tablets. As you can see, we can achieve hardness 7 with chemically strengthened glass and usually 6 with thermally strengthened glass. Gorilla glass is also chemically strengthened glass, patented by the Corning company and it is the strongest that we can achieve in the cover glass to protect the screen.

A couple more words about Gorilla glass. Now there is the sixth generation of Gorilla Glass on the market. The goal for Corning company and Gorilla Glass is to make the glass as strong and as light as possible, because most of the cases are handheld devices, where we want the glass to be light, that is why we want to make it very thin. We have also other companies that are making equivalents of Gorilla Glass, like Dragontrail from AGC or Xensation from Shott. They are not so popular but in many mobile phones or tablets on the market you can find these types of glass.

Now let us talk about the painting. We know the types of glass that we use in TFT LCD displays, we know how to make the glass stronger, we know the surface treatments, how to make the glass less reflective or anti-fingerprint or antibacterial, but it is not enough because glass will only be transparent. If we want to cover it, we need to paint it. Typically, we paint glass with the technique called Screen Printing. It is the most popular, cheapest and fastest technique.

We laminate glass mainly because of two reasons. One is mechanical strength and impact. We use it even in our homes. Many windows used nowadays are anti-vandal and that means they are laminated glass, and they are extraordinarily strong. The other reason to laminate glass is to put a film inside with some properties, usually to block the UV or IR light. IR means infrared so heat and UV means ultraviolet, short wavelength, extremely dangerous for electronics. When we have an outdoor application, some customers want to protect the displays, touchscreens or the e-paper displays also against UV. Then we use laminated glass and as you can see on the chart above the IR cut film and UV cut film are both transparent for visible light. We can see everything through them, but what is higher and what is lower is cut by UV and IR films. Most often we use only UV cut film because UV is more dangerous, for example it makes the film sensors for capacitive touchscreens turn yellow or it can decrease the contrast of the TFT (Thin Film Transistor) display by damaging the polarizer or color filters. The IR film is used in some applications to protect the display from heat. If we add it, we can decrease the temperature of the display surface. In another video we were talking about High-TN, so liquid crystals that can work in very high temperatures. For this kind of liquid crystals, we usually do not need to decrease the temperature of the surface because they can go up to 100 or 110 degrees, but regular displays can work up to 50- or 70-degrees maximum temperature. Using the IR cut film can solve the problem with blackening and increasing the display temperature too much.

Different displays have different characteristics, just tell Panox Display your application, and operating environment, Panox Display will suggest a suitable display for you.

But Panox Display is not a school, if customers don`t know the basic knowledge to design circuit boards, we suggest using our controller board to drive the display.

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.

If you don`t know or don`t want to write a display program on Raspberry Pi, it`s better to get an HDMI controller board from us, and Panox Display will send a config.txt file for reference.
