Lcd Rear Projection High-temperature Critical Circuit Design,

The paper does research on the key circuit of the rear LCD projector TV system. In the paper, we analyze the structure of the LCD optical engine and a series of LCD drive and image processing solutions. Based on analyzing the performances and feature of all kinds of solutions, we developed a full circuit for high-end rear LCD projector TV. On the procedure of key circuit designing, the paper take full advantage of the existing experiences of design LCD engine. the paper also have a delicate designing on bright, contrast and chroma in image processing board. The rear LCD projector TV using the solutions have come into market and also have good sales outcome. This proved the result of the research had high competition and high reliably.
