Abstract

The invention discloses a display device, which comprises scanning wires, data wires, pixel transistors, pixel electrodes, a grid driver, a source driver and a discharge circuit. The data wires and the scanning wires are mutually crossed. Each pixel transistor is electrically coupled with the corresponding scanning wire and the corresponding data wire respectively, and each pixel electrode is electrically coupled with the corresponding pixel transistor. The grid driver is electrically coupled with the scanning wire, and the source driver is coupled with the data wire. The discharge circuit is electrically coupled with the grid driver and the data wire and is started to control the grid driver to simultaneously conduct the pixel transistors when the display device is closed, and the pixel electrode is electrically coupled with a reference voltage through the data wire and the discharge circuit. The invention also discloses a ghost eliminating method corresponding to the display device.

Description

technical field [0001] The present invention relates to the field of display, and in particular to a display device and a corresponding method for eliminating image sticking. Background technique [0002] With the development of science and technology, flat panel display devices (such as liquid crystal display devices) are widely used in mobile phones, notebook computers, desktop displays due to their advantages of high image quality, small size, light weight and wide application range. Devices and various consumer electronic products such as televisions have gradually replaced traditional cathode ray tube display devices and become the mainstream of display devices. [0003] As is well known, known flat panel display devices generally sequentially enable pixels on the display panel through a gate driver, and output display data to the pixels on the display panel through a source driver, so that the flat panel display device displays images. However, when the known flat-pan...
