Abstract

Embodiments of the present invention provide a touch signal anti-interference method and device. When scanning the touch signal, the scanning frequency of the touch driving circuit is increased, so as to obtain more touch signal data corresponding to the disturbed condition, and then the comparison is performed to remove the abnormal touch signal data, and The touch signal data obtained by final screening is output, so as to achieve the purpose of improving the touch effect of the touch screen and the accuracy of reporting points of the touch screen.

Description

technical field [0001] The present invention relates to the technical field of touch signals, and in particular, to an anti-interference method and device for touch signals. Background technique [0002] With the continuous improvement of the display panel manufacturing technology, people's performance and requirements for the touch screen are also gradually improved. [0003] Today, the touch screen has been applied to many display devices, and is accepted by the majority of users due to the advantages of high efficiency, fast and convenient operation of the touch screen. At present, the touch screen can be divided into an external touch screen, a surface-covered touch screen and an in-cell touch screen according to the composition structure. Among the above-mentioned different types of touch screens, the in-cell touch screen is widely used due to its advantages of low cost and few processes, especially in vehicle display products. Due to the high degree of electrificatio...
