Abstract

The invention provides a touch display device and a control method thereof. The touch display device includes a display panel and a panel driver. The display panel displays a video and to receive a touch operation. The panel driver includes a timing controller and a memory module. The timing controller generates a clock signal, each cycle of the clock signal including N display periods and N touch periods, the total time of the N display periods corresponding to a frame of a video signal, and the total time of the N display periods and the N touch periods corresponding to one cycle of the video signal, in which N is a positive integer. The panel driver alternately drives the display panel to display images during each of the N display periods and to detect the touch operation during each of the N touch periods. The memory module is configured to sequentially store the image data corresponding to one of the N display period of the video signal according to the clock signal.

Description

technical field [0001] The present invention relates to a touch display device, and in particular to a sensing circuit in a touch panel. Background technique [0002] Touch display devices are widely used in various electronic devices, such as notebook computers, personal digital assistants (PDAs), video cameras, and so on. [0003] Users can execute related functions by clicking or moving on the screen of the touch display device. However, as the application of panels with large size or high resolution becomes more and more common, the sensitivity of touch operation must be increased to provide better user experience. [0004] Therefore, how to improve the sensitivity of touch operation in high-resolution applications is one of the current important research and development topics, and has also become an urgent need for improvement in related fields. Contents of the invention [0005] In order to solve the above problems, an aspect of the present disclosure provides a t...
