液晶电视动态LED背光源技术及其应用

摘要

The new LED backlight technology for LCD's, It is in the display and the extensive use of television has already begun. Electro-optical efficiency of the current LED is not high enough. Constant brightness LED backlight can not further improve the quality of images displayed. And it is the power into the heal affected the reliability of the product. This paper is based on FPGA technology, district technology dynamic control LED backligjht. The dynamic contrast feature significantly improves the LCD image quality, which greatly reduces the actual service power of liquid crystal display (TV) and makes contribution to improving image quality and energy saving.%目前LED的电光效率还不够高,亮度固定的LED背光源影响到显示图像的画质不能进一步提高,而且耗能发热而影响产品可靠性.本文研究的基于FPGA技术的分区动态控制LED背光源技术,其动态对比度特性明显的提高了液晶图像画质,大大的降低了液晶显示嚣(电视机)的实际使用功率,为提高画质和节能做出进一步的贡献.
