Problems solved by technology

[0006] However, with the gradual improvement of the resolution of the liquid crystal display device, for example, the resolution of the liquid crystal display device of a mobile phone gradually adopts 2K (eg, 2560x1440) resolution or even higher resolution, and the display refresh rate generally adopts 60HZ, the line gaps and frame gaps will be significantly compressed, and if the touch sensing is performed on the touch sensing electrodes only in the line gaps and frame gaps, the problem of insufficient touch sensing will be caused by the obvious lack of time

Abstract

The invention provides a touch display device and electronic equipment. The touch display device includes a touch display panel and a driving circuit. The touch display panel includes a plurality of pixel electrodes and a plurality of common electrodes. The drive circuit provides the first grayscale voltage to the pixel electrodes and the first common voltage to the plurality of common electrodes, drives the touch display panel to perform image display refresh, and further drives the common electrodes to perform touch sensing, Wherein, both the first grayscale voltage and the first common voltage are signals modulated by a modulation signal. The electronic equipment includes the touch display device.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display device and electronic equipment having the touch display device. Background technique [0002] Generally, the touch display device includes three types of touch display panels: plug-in, On-Cell (on-box), and In-Cell (in-box or built-in). With the development of technology, in order to further thin the touch display panel and increase the brightness of the touch display panel, the In-Cell type touch display panel has gradually become a trend. [0003] The touch display device is illustrated as an example of a liquid crystal display device. Generally, a liquid crystal display device includes a liquid crystal display panel and a driving circuit for driving the liquid crystal display panel to perform image display and touch sensing. The liquid crystal display panel includes a plurality of scanning lines, a plurality of data lines, a plurality of transis...
