Abstract

The embodiment of the invention provides a touch signal anti-interference method and device. When a touch signal is scanned, the scanning frequency of the touch drive circuit is increased, more corresponding touch signal data under the interference condition are obtained, then comparison is carried out, abnormal touch signal data are removed, and finally the touch signal data obtained through screening are output, and the purposes of improving the touch effect of the touch screen and improving the point reporting accuracy of the touch screen are achieved.

Description

technical field [0001] The present invention relates to the technical field of touch signals, in particular to an anti-interference method and device for touch signals. Background technique [0002] With the continuous improvement of display panel manufacturing technology, people's performance and requirements for touch screens are gradually increasing. [0003] Today, the touch screen has been applied to many display devices, and has been accepted by a large number of users due to its advantages of high efficiency, quickness and convenience in operation. At present, touch screens can be divided into plug-in touch screens, surface-covered touch screens, and built-in touch screens according to their composition and structure. Among the different types of touch screens mentioned above, the built-in touch screen is widely used due to its advantages of low cost and less process, especially in vehicle display products. Due to the high degree of electrification of the vehicle wh...
