Plasma display, also known as the PDP, is a CRT (cathode ray tube), LCD (liquid crystal display) after the latest generation of display, characterized by a very thin thickness, good resolution. In terms of working principle, plasma technology has obvious difference compared with other display modes, and is one step ahead in structure and composition. Its working principle is similar to the ordinary fluorescent lamp and the television color image, by each independent phosphor pixel luminous combination, therefore the image is bright, bright, clean and clear. In addition, the most prominent feature of the plasma display equipment is that it can be ultra-thin, can easily do 40 inches above the complete flat screen, and the thickness of less than 100 mm (in fact, it is also a weakness: that can not be done less.) At present, the smallest product is only 42 inches, only for large screen users, and home theater and so on.
Plasma display (Pdp,plasma display Panel) since the beginning of the 90 's into commercial production, its performance indicators, good product rate and so on, and prices have been falling. In particular, since 2005, its cost-effective further improved, from the early stage to commercial-oriented to the main family.
Imaging principle
The imaging principle of plasma display technology is to arrange thousands of sealed small low-pressure gas chambers on the display screen, by activating the current to emit ultraviolet light that is invisible to the naked eye, the ultraviolet light hits the red, Green, blue 3-color fluorescent body on the back glass and emits visible light that the naked eye can see.
Superiority
Thin thickness, high resolution, occupy less space and can be used as wall-mounted TV in the home, representing the future development trend of computer monitors.
Working principle
The
is the filling of a mixture of gas between two thin glass panels, the application of voltage to produce ionic gas, and then the plasma gas discharge, and the substrate in response to the fluorescence, resulting in color images. It takes the plasma tube as the luminous element, a large number of plasma tubes are arranged together to form the screen, each plasma corresponding to each small room is filled with neon xenon, in the plasma tube electrodes with high pressure, sealed in between two layers of glass in the plasma Tube Chamber of gas will produce ultraviolet light, And the red-green-blue tri-phosphor phosphor on the flat panel display is emitted visible light. Each plasma tube acts as a pixel, composed of these pixel shades and color variations to produce a variety of grayscale and color images, similar to the CRT glow. Plasma TV, also known as "wall-mounted TV", is not affected by magnetic force and magnetic field, with a thin body, light weight, large screen, bright colors, clear picture, high brightness, low distortion, visual feeling comfortable, save space and so on.
