Abstract

The present invention provides a touch control display device, a touch control display panel and an array substrate. The array substrate comprises a substrate; a plurality of pixel units arranged on the substrate; multiple rows of touch control electrodes, each touch control electrode covering the plurality of pixel units; a driving circuit driving the touch control electrodes; touch control leads which are respectively connected to the corresponding touch control electrode through a first through hole, and used for connecting the corresponding touch control electrode to the driving circuit; and at least one auxiliary lead which is positioned between the two adjacent touch control leads, is connected to the touch control electrode where a third through hole is located through the third through hole, and is broken between the two adjacent touch control electrodes, wherein for each row of the touch control electrodes, the touch control electrodes are provided with auxiliary through holes. According to the touch control display device, the touch control display panel and the array substrate, the problem of unevenly displayed strips visible to human eyes on display frames is solved.

Description

technical field [0001] The present invention relates to the field of display and touch control, in particular to a touch display device, a touch display panel and an array substrate. Background technique [0002] With the development of human-computer interaction technology, touch technology is increasingly used on various displays. Capacitive touch technology is widely used due to its advantages of wear resistance, long life, low maintenance cost for users, and support for gesture recognition and multi-touch. [0003] Capacitive touch technology can be divided into self-capacitive touch technology and mutual-capacitive touch technology according to the detection method of capacitance between different objects. Self-capacitive touch technology detects the presence, position, and motion of an input object on a touch screen based on changes in capacitance between electrodes and ground caused by the input object. The mutual capacitive touch technology detects the existence, p...
