Technical features color PDP

Bright and easy to see, good contrast, thin and light, large screen, fast response, wide viewing angle, multi-level gray scale, high reliability, and can achieve full-color display. Wide viewing angle is large-screen wall-mounted TV and HDTV will be exhausted one of the conditions. The use of mixed rare gas discharge generated pose outside RGB trichromatic phosphor excitation, and using time-modulation (pulse number modulation) grayscale technology, up to 256 and 16.77 million colors, COG LCD Display obtained with the CRT as wide color gamut, with good color reproduction, PDP screen brightness is uniform, no bright and dark areas of the points, the image does not appear to take the geometric transformation and color shift phenomenon, there is no focus problems, less susceptible to external magnetic fields, with better environmental adaptability, with a very steep or value characteristic, suitable for time-division multiplexing driver; has a memory effect, even if the increased display capacity, and it is easy to obtain high brightness display; structure and manufacturing process is simple, without such as TFT high precision, small investment, suitable modern mass production; has storage characteristics, high brightness, large screen, full-color, good contrast, making images clearer, more vivid colors, feel more comfortable viewing angle, showing the effect is more ideal; color reproduction is good, rich gradation can be more than 256, the color gamut is close to CRT.

A rapidly changing screen response speed, suitable for displaying animated images, and playback video signal; wide viewing angle, both horizontally and vertically upward angle up to 160 degrees, can provide exceptionally bright, uniform and smooth image and a larger viewing angle; small, light weight, thin, pure flat, long life, particularly for public information display, wall-mounted large-screen TV and automatic monitoring systems. Resistant ions emitted through an electrode base material, dielectric protective film phosphor long life, life of a PDP can hundreds of thousands of hours, and working life of the color PDP is usually up to 2-3 million hours, which is typical of the lcd module  25,000 hours lifetime value considerably, but far longer life projection tube. But there is also the inadequacies of PDP, such as thin glass substrate on the display, you can not put too much or too little pressure, but can not bear the weight. Each pixel on the display is a separate self-luminous, power consumption, the monitor must be installed on the backplane sets of fan for heat dissipation. In addition, PDP driving voltage is high, the price is also relatively high. As the manufacturing process and assembly technology improvements, the cost is declining, practicality is increasing, increasing the contrast in the display quality also improved.
