摘要
Abstract
LCD screens is asked for displaying some standard signals when the characteristics and qualities are being checked. Since the signals generated by some available facilities are analog signals such as AV signal, VGA signal or YPbPr signal, they are not suitable for testing the digital LCD screens. Those analog signals must be transformed to digital LVDS format by graphic processing unit (GPU), before they are sent into LCD screen scanning circuit to display some standard graphs. Distortion and attenuation are inevitable during this process, which will influence the quality of those standard graphs. Therefore, a new type of signal generator that can directly generate digital standard graph signals was designed. These signals can be sent into LCD screen directly via LVDS port after they are transformed to LVDS signal. The distortion and attenuation of signals can be avoided by this means.关键词
