由于液晶显示器每一个点在收到信号后就一直保持那种色彩和亮度，恒定发光，而不像阴极射线管显示器（CRT）那样需要不断刷新新亮点。因此，液晶显示器画质高且不会闪烁。(Since each point in the liquid crystal display keeps the color and brightness after receiving the signal, it has a constant luminescence rather than a new bright spot that needs to be refreshed as a cathode ray tube display (CRT). Therefore, liquid crystal displays are of high quality and will not blink.)
