TFT-Character LCD Modules technology design ideas

Is the current TFT-LCD flat panel display (FPD) of the mainstream. This paper describes the design ideas TFT-LCD technology and material selection, and in the last part of the list of foreign countries in the TFT-LCD existing computer-aided design software for everyone preliminary understanding of TFT-LCD design provides technical reference. Lcd display modules
A. First set of indicators of performance parameters
Design can be based on market needs and user requirements, taking into account the capacity of the production line equipment, the planning of new products TFT-LCD screen size, brightness, contrast, resolution, the opening ratio, response time, scanning frequency, the drive mode, the pixel pitch, sub-pixel arrangement, backlight type, environmental conditions, anti-glare anti-reflection treatment specifications indicators.
Two. Select for TFT-LCD glass
TFT-LCD flat glass for the boron-alkali aluminosilicate glass. Requires precise size, surface roughness, softening point above 650 degrees, no scratches and bubbles, good chemical stability, low thermal expansion coefficient. Phone with a glass thickness of 0.4mm, PC and LCD TVs generally use 0.6 or 0.7mm glass. Now the market supply of TFT-LCD flat glass altogether 4. Corning 1737 respectively, and EAGLE2000 type, Nippon Electric Glass of OA10 and OA21 type Asahi AN100 type, NH The NA35 type. Fifth-generation glass substrate size 1100X1300mm, mainly produced by melt stretching Corning glass or float glass production of Asahi Glass.
III. Selected according to the purpose color filter (CF)

The color filter is to achieve the TFT-LCD color display key component. In the TFT-LCD, the color filter for the front glass substrate. Its manufacturing process is to set the black matrix (BM), and respectively to make red (R), green (G), blue (B) three-color dot, the next in the R, G, B coated with a protective film, and the production driving the liquid crystal with a transparent conductive film (ITO). The pigment printing process based.
CF is about nine manufacturers, including convex plate printing and Dai Nippon Printing, etc. In the fifth alternative color filter manufacturing technology development to invest more. The main consideration when designing the selected CF whether attached column CF and color (RGB) are arranged. Column with the color filter CF is a black matrix (BM), through the photolithography process has a cylindrical preform liner material, will be omitted in the manufacturing process, distribution screen spacer of the processes. Color (RGB) with the arrangement of RGB stripe arrangement, RGB and RGB delta arrangement arranged in a matrix. Stripe arrangement is characterized by a small pixel pitch, suitable for computer monitors use. Matrix arrangement can be relatively easily obtained color natural images. Triangular arrangement of the larger aperture ratio, commonly used in small and medium sized LCD TV. COG LCD Module
