Abstract

The invention discloses a display device, which comprises a plurality of pixels, a plurality of gate lines, a timing control circuit and a gate drive circuit. A plurality of gate lines are electrically coupled to the pixels. The timing control circuit is used to provide a start pulse signal. The gate driving circuit is electrically coupled to the timing control circuit and the gate lines, and is used to receive the start pulse signal, and responds when the scanning frequency of the display device is switched from the first frequency to the second frequency, and the first frequency is higher than In the second frequency, the gate driving circuit receives a high-level start pulse signal during more than half of one frame of the display device, and outputs a plurality of gate signals to the gate lines according to the start pulse signal.

Description

technical field [0001] The present invention relates to a display technology, and in particular to a display device. Background technique [0002] When the display device is displaying images, sometimes there will be image defects, such as breakage or tearing in the image. The cause of the above situation is that the number of screens output by the display card of the computer is not synchronized with the scanning frequency of the display device. [0003] In order to solve the above problems, the industry has developed a vertical synchronization (V-Sync) function. However, when the vertical synchronization is used to solve the picture defect, the problem of picture delay will be derived additionally. Subsequently, the industry re-developed the adaptive vertical synchronization (G-Sync) function to solve the picture defects without deriving the problem of picture delay. [0004] This shows that above-mentioned existing mode obviously still has inconvenience and defect, and ...
