Be more specific full-color LED large screen display 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 to light by an integrator (Integrator) large-screen projector projects the light homogenization three primary colors by a color ring (Color Wheel), the light into R, G, B three colors, then The color imaged by the lens on the DMD. Synchronous signal method, the rotation of the lens of the digital electrical signal, the continuous light into gray scale, with the R, G, B three colors and the color shown, 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 of excess weight, the key technical indicators are far less than LCD and plasma, its biggest flaw is the high operating costs: long uninterrupted work and DLP rear projection bulb will speed up the aging rate , Rear Lamp only a few thousand hours of life, if you run 24 hours a day, a few months will need to replace the projection bulb, giving users no small operational expenses. LCD and rear projection only with the life of the light-emitting part related to the backlight lamp due for replacement after use or replace the lamp can be. But the life of a plasma screen about the large-screen display, maturity can only be scrapped after use, can not be repaired; burns symptoms manifested when a still image after staying in one position for a long time, it will leave a shadow on the screen. The liquid crystal projection display principle determines the screen does not burn LCD large screen systems, but plasma burns are quite serious, this is entirely the plasma gas, such as caused by light-emitting principle. Part of the LCD backlight in LCD splicing screen side cause a certain gap, after the use of LED backlighting, LCD patchwork and rear projection, plasma fairly. The resolution determines the clarity of the screen, a relatively high resolution LCD monitor, the picture is more delicate, more content can be displayed.
