Abstract
Official abstract text for this publication.
When a SLEEPIN Command is inputted to the liquid crystal display device, the liquid crystal display device controls a source driver and a gate driver to generate an alternating current voltage and apply the generated alternating current voltage to a liquid crystal layer, in order to eliminate charge storage due to impurity ions distributed unevenly due to a polarity bias caused by a voltage applied to the liquid crystal layer until a point of time when the Command is inputted. In this manner, the liquid crystal display device shifts to a sleep period in a state where the charge storage due to the unevenly distributed impurity ions is eliminated. Therefore, when the liquid crystal display device resumes from the sleep period, generation of an afterimage due to burn-in of liquid crystal and generation of a flicker due to deviation of an optimum common voltage do not occur.
First claim
Opening claim text (preview).
1 . A liquid crystal display device that applies a voltage corresponding to input image data to a liquid crystal layer of a display unit, and displays an image represented by the input image data on the display unit, the liquid crystal display device comprising: a drive unit configured to apply the voltage corresponding to the input image data to the liquid crystal layer; and a display control unit configured to generate an alternating current voltage upon receiving an off signal that stops a…
