Illumination influence on the Flicker shift of ADS mode TFT-LCD
the illumination influence on the flicker shift of the Advanced Super Dimension Switch (ADS) Mode Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has been studied in this paper. First
this article researched the flicker shift of LCD under the condition of the standard backlight brightness
then tested the flicker shift of the samples without backlight or reducing the backlight brightness. Finally
this article studied the influence of lighting panel after a period of time on flicker shift. The experimental results showed that the illumination makes cell to generate ions. Due to liquid crystal polarization
a force will emerge when driving signal voltage exists. The existence of the force will cause ions to be accumulated
forming residual DC which results in flicker shift. Flicker shift will weaken as backlight brightness decreases. These results have great guiding significance for LCD system design and display quality improvement to a certain extent.
