LCD screen, PDP screen, DLP big-screen TV wall

In the growing field of surveillance technology, high-definition monitor will also be a shining star, re-examine it in the light of the world around us. With the increasing development of monitoring technology, high-definition surveillance technology as one of the main directions of development, combined with network technology brings new changes, competition in the market continue to meet demand, tend to think about a rational, high-definition monitors are is a high-profile, high demand into our world.

LCD LCD TV wall mosaic

LCD LCD splicing DID Korea currently represented on the display market although there SHARP, LG, NEC and other brands, but DID outshine its excellent value for money in the LCD panel stitching techniques. The so-called large-screen LCD LCD, LCD display unit is the use of mosaic way through splicing control software system to implement a large-screen display screen body mosaic effect.

As a TV wall mosaic display terminals, OLED Display Despite these advantages, but as a mosaic TV wall display unit, its shortcomings are fatal: it is the current patchwork teach their large, and the display unit in the three largest TV wall mosaic, so many Users had to reluctantly give up. LCD TV wall mosaic with a thin, light weight, low power consumption, long life, no radiation, etc., and its delicate screen, high resolution, excellent performance on key performance indicators, has made it become the mainstream of development prospects.

Large plasma-screen TV wall system

Plasma display panels (PDP) is a use of gas discharge display technology, which works with the lamp is very similar. It uses a light emitting element such as a plasma tube, each plasma tube corresponds to a pixel on the screen, the screen as a glass substrate, spaced from the substrate, forming a discharge space. Filled into the discharge space neon, xenon, an inert gas mixture as a working medium, the inner surface of two glass substrates coated with a metal oxide conductive film as the excitation electrode. The plasma discharge generates ultraviolet rays, ultraviolet rays excite phosphor coated with red, green and blue phosphor screen, visible light emitting phosphor screen, the image appears. When added to the voltage on the electrodes, the discharge space of the mixed gas plasma discharge phenomenon will occur, also known as plasma effects.

DLP TV wall system

DLP. This technique is to first go through a digital video signal processing, and then the light is projected. Specifically, DLP projection technology is the application of a digital micromirror chip (DMD) to do the key elements to achieve digital optical processing. The principle is that a light source by an integrator (Integrator), homogenizing the light, the three primary colors through a color wheel (ColorWheel), separating the light into R, G, B three colors, and then imaged by the lens color DMD on.

Currently, more common large-screen TV wall system, according to work is usually divided into three main types of display units: low temperature 160x160 lcd TV wall mosaic display unit, PDP display unit and DLP rear projection TV wall mosaic mosaic display unit. The former two of which belong to the flat panel display unit splicing system, which belongs to the projection unit splicing system.
