Be more specific, that is, DLP projection technology is the application of a digital micromirror chip (DMD) to do the essential components in order to achieve digital optical processing. The principle is that a light source by an integrator (Integrator), uniform light, the three primary colors through a color wheel (Color Wheel), splits the light into R, G, B three-color, and then imaged by the lens color DMD on. Method to synchronize signals, rotating lens digital telecommunications numbers, the continuous light into gray scale, with the R, G, B three colors and the color shown large-screen, and finally through the lens projection imaging. DLP relative to the other two advantages in its patchwork stitching small, simple operation and maintenance. But its shortcomings are obvious: for example, the volume and weight of excessive LED full-color large-screen display, the key technical indicators are far less than LCD and plasma, its biggest flaw is the high operating costs: a long and uninterrupted work will accelerate DLP rear projection bulb aging rate, Rear Lamp only a few thousand hours of life, if the unit is running 24 hours a day large-screen devices, we need to replace the projection bulb months, giving users no small operational expenses. PDP is a self-luminous display technology, no background light, so there is no problem of viewing angle and brightness uniformity. The three-color phosphor share the same plasma tube design also makes it avoids focusing and convergence problems, you can achieve a very clear image. However, plasma high voltage power-hungry, energy consumption, life has deficiencies, the use of 5000 to 10,000 hours half the screen brightness will decay and hard work at an altitude of 2,500 meters. PDP plasma screen in the stitching, currently South Korea's Orion MPDP represented, as other ordinary plasma splicing in the market and rare, so are not described here. MPDP because of its patchwork of small, thin, and get a lot of customers. But its shortcomings are intolerable: In addition to a large power consumption and heat, as well as severe burns, and does not fit the monitor screen for a long time to display a static environment. And then for the stitching, the whole higher temperature LCD large-screen display system, causing the device easy to burn. The resolution also makes many users criticized: only 854 × 480, 800 × 600 or even lower than computer graphics driver is not installed, and a closer look almost unbearable.
