Abstract

The invention provides a fast discharge circuit, a display device, a fast discharge method and a display control method. The fast discharge circuit comprises a discharge circuit; a control end of the discharge unit is connected with a drive integrated circuit, a first end of the discharge unit is connected with a grating line of the display device, and a second end of the discharge unit is connected with a display level end in the display device; the display level end is connected with the drive integrated circuit; the discharge unit is used for controlling the display level end to write a first level into the grating line when the display device is in abnormal power failure. By the fast discharge circuit, the display device, the fast discharge method and the display control method, problems of high cost and high quantity of changed masks required in display panel manufacture in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of discharge control, in particular to a fast discharge circuit, a display device, a fast discharge method and a display control method. Background technique [0002] LTPS (Low Temperature Poly-silicon, low-temperature polysilicon technology) shows that the leakage current Ioff is relatively small due to the process design and the double-gate structure design. Therefore, when the display panel is abnormally powered off, the LTPS display product has a slow charge release process due to the small leakage current Ioff, and easily generates charge residue. Therefore, after the display device is abnormally powered off, it is necessary to provide a discharge unit to quickly discharge the charge in the pixel region of the Panel (display panel). Existing fast discharge circuits applied to display devices need to design additional space for the discharge cells in the GOA (Gate On Array, array substrate row drive) ci...
