Abstract

The invention provides an embedded touch display panel which comprises multiple touch driving electrodes and multiple touch sending electrodes. The multiple touch driving electrodes and the multiple touch sending electrodes are located in a display zone of the embedded touch display panel and are arranged in staggered mode. The multiple touch driving electrodes are divided into multiple touch driving electrode groups, each of the multiple touch driving electrode groups comprises two of the touch driving electrodes, and the touch driving electrodes in each of the multiple touch driving electrode groups are mutually and electrically connected through connecting leads in a peripheral zone located outside the display zone of the embedded touch display panel.

Description

technical field [0001] The present invention relates to an in-cell touch display panel, and in particular to an in-cell touch display panel capable of improving the voltage uniformity of touch driving electrodes in a display stage. Background technique [0002] With the advancement of the production technology of electronic products, most of the handheld devices such as smart phones and tablet computers already have the function of touch operation, and the touch operation can make the use of the handheld device more convenient for users. Currently developed touch technologies for display devices include one glass solution (OGS), on-cell touch and in-cell touch. touch) technology, etc. Among these touch technologies, the in-cell touch technology is to manufacture the touch electrodes in the liquid crystal pixel layer of the display panel, so it has the advantage of reducing the thickness of the display panel. However, for the in-cell touch display panel, image display and t...
