Abstract

The invention discloses a display device. The display device comprises a display module, a data driver, a power module and a time sequence controller, wherein the data driver is connected with the display module; the power module is respectively connected with the display module and the data driver; and the time sequence controller is respectively connected with the display module, the data driver and the power module for detecting the input voltage of the display module. The invention also discloses a liquid crystal display and a method of eliminating a ghost. When the input voltage of the display module is detected by the time sequence controller to be preset voltage, the time sequence controller inputs a preset black screen signal or a preset white screen signal to the display module through the data driver, the display module displays the preset black screen or the preset white screen, a ghost phenomenon existing in the case of abnormal shutdown is eliminated, and the reliability of products is thus improved.

Description

technical field [0001] The invention relates to the technical field of display manufacturing, in particular to a display device, a liquid crystal display and a method for eliminating image sticking. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) has been widely used recently, and replaces cathode ray tube display (Cathode Ray Tube, CRT) to become one of the mainstream displays of the next generation. With the improvement of semiconductor technology, TFT-LCD has the advantages of low power consumption, thin and light weight, high resolution, high color saturation, and long life, so it is widely used in computer LCD screens and LCD TVs, etc. closely related electronic products. [0003] The prior art provides a liquid crystal display. When the liquid crystal display needs to be turned off, the liquid crystal display turns on each pixel unit in the liquid crystal display module through the gate driver, so that the residual charge...
