low-power color tft lcd display for handheld embedded systems price

An LCD (Liquid Crystal Display) is a standard display device for hand-held embedded systems. Today, color TFT (Thin-Film Transistor) LCDs are common even in cost-effective equipments. An LCD display system is composed of an LCD panel, a frame buffer memory, an LCD and frame buffer controller, and a backlight inverter and lamp. All of them are heavy power consumers, and their portion becomes much more dominant when running interactive applications. This is because interactive applications are often triggered by human inputs and thus result in a lot of slack time in the CPU and memory system, which can be effectively used for dynamic power management. In this paper, we introduce low-power LCD display schemes as a system-level approach. We accurately characterize the energy consumption at the component level and minimize energy consumption of each component without appreciable display quality degradation. We develop several techniques such as variable-duty-ratio refresh, dynamic-color-depth control and backlight luminance dimming with brightness compensation or contrast enhancement.

As mentioned, TFT is a subset of the LCD technology. TFT is an active matrix display. There are active matrix displays and passive matrix displays used in LCD flat panels of computers, phones, and so on. The images produced by active matrix are responsive and enable a wider angle of view compared to passive matrix display. Passive matrix displays, on the other hand, use a grid of horizontal and vertical wires to display an image. In this case, the charge of two wires is altered to change a pixel at intersection. The response time of producing an image with the passive matrix technology is much slower than active matrix. Also, at times, the image quality produced by passive matrix is blurred and pixelated. Active matrix, in comparison, offers many more advantages and a fine image quality, and hence is widely used in making 4.3-inch TFT LCD display module touch screens. The pixels on the TFT screen are arranged in a row-column configuration. The glass panel has an amorphous silicon transistor on which the pixels are attached. This enables each pixel to get a new charge and keep it consistent even after the screen is refreshed to load a new image. So, each pixel continues to be in its maintained state when other pixels are being used. This is one reason why this technology is called active matrix.

Display Mode: This indicates the image resolution and maximum number of colors available. Here, the display mode is usually white with some transmissivity.

Interface: The display interface helps humans exchange information with software. For instance, you need to control color, brightness, and other parameters as there are many interface options. This display has RGB interface and a TFT-LCD display type.

What we are talking about TFT LCD, it is a LCD that uses TFT technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments without TFT in each pixel.

The TN type TFT LCD display is one of the oldest and lowest cost type of LCD display technology. TN TFT LCD displays have the advantages of fast response times, but its main advantages are poor color reproduction and narrow viewing angles. Colors will shift with the viewing angle. To make things worse, it has a viewing angle with gray scale inversion issue. Scientist and engineers took great effort trying to resolve the main genetic issues. Now, TN displays can look significantly better than older TN displays from decades earlier, but overall TN TFT LCD display has inferior viewing angles and poor color in comparison to other TFT LCD technologies.

IPS TFT LCD display was developed by Hitachi Ltd. in 1996 to improve on the poor viewing angle and the poor color reproduction of TN panels. Its name comes from its in-cell twist/switch difference compared with TN LCD panels.The liquid crystal molecules move parallel to the panel plane instead of perpendicular to it. This change reduces the amount of light scattering in the matrix, which gives IPS its characteristic of much improved wide viewing angles and color reproduction. But IPS TFT display has the disadvantages of lower panel transmission rate and higher production cost compared withTN type TFT displays, but these flaws can’t prevent it to be used in high end display applications which need superior color, contrast, viewing angle and crispy images.

The mono-domain VA technology is widely used for monochrome LCD displays to provide pure black background and better contrast, its uniformly alignment of the liquid crystal molecules makes the brightness changing with the viewing angle.

MVA solves this problem by causing the liquid crystal molecules to have more than one direction on a single pixel. This is done by dividing the pixel into two or four regions – called domains – and by using protrusions on the glass surfaces to pretilt the liquid crystal molecules in the different directions. In this way, the brightness of the LCD display can be made to appear uniform over a wide range of viewing angles.

This is an LCD technology derived from the IPS by Boe-Hydis of Korea. Known as fringe field switching (FFS) until 2003, advanced fringe field switching is a technology similar to IPS offering superior performance and color gamut with high luminosity. Color shift and deviation caused by light leakage is corrected by optimizing the white gamut, which also enhances white/grey reproduction. AFFS is developed by Hydis Technologies Co., Ltd, Korea (formally Hyundai Electronics, LCD Task Force).

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. (Reference)

The AFFS is similar to the IPS in concept; both align the crystal molecules in a parallel-to-substrate manner, improving viewing angles. However, the AFFS is more advanced and can better optimize power consumption. Most notably, AFFS has high transmittance, meaning that less of the light energy is absorbed within the liquid crystal layer and more is transmitted towards the surface. IPS TFT LCDs typically have lower transmittances, hence the need for the brighter backlight. This transmittance difference is rooted in the AFFS’s compact, maximized active cell space beneath each pixel.
