1results about How to "Improve touch reporting rate" patented technology

This invention provides a touch display device and a driving method. The touch display device includes a touch driving circuit and a channel switching module. The touch driving circuit includes multiple touch channels, which are divided into multiple first touch channels and multiple second touch channels. The multiple first touch channels correspond to multiple first electrode blocks in a first touch area, and the multiple second touch channels correspond to and are connected to multiple second electrode blocks in a second touch area. The channel switching module is used to connect the corresponding connections between the multiple first touch channels and the multiple first electrode blocks, and disconnect the connections between the multiple first touch channels and the multiple second touch channels; or, it is used to disconnect the corresponding connections between the multiple first touch channels and the multiple first electrode blocks, and connect the connection between the first touch channel receiving the touch detection signal and the corresponding second touch channel in the scanning direction. This invention can be used to achieve a high touch reporting rate in a local area, improving the user experience.
