Abstract

The invention provides an embedded self-capacitance touch control device and a manufacturing method thereof, the embedded self-capacitance touch control device comprises a plurality of touch control electrode blocks which are arranged independently and distributed in a matrix, the plurality of touch control electrode blocks are arranged into X columns along a first direction and arranged into Y rows along a second direction, and both X and Y are positive integers; each touch electrode block is provided with a plurality of contact holes, and the number of the contact holes in the touch electrode blocks arranged from top to bottom in the second direction is sequentially decreased progressively; the device further comprises a plurality of touch signal transmission lines distributed in the second direction, one end of each touch signal transmission line is electrically connected with the touch electrode block through a contact hole in the touch electrode block, and the other end of each touch signal transmission line is connected with an external control circuit. According to the device, different numbers of contact holes are formed in different touch electrode blocks, so that the impedance capacitance of connecting lines between the touch electrode blocks and an external control circuit is homogenized, the signal-to-noise ratio difference between the touch electrode blocks is reduced or eliminated, and the touch uniformity of the panel is improved.

Description

technical field [0001] The invention relates to the field of display device manufacturing, in particular to an in-cell self-capacitance touch device and a manufacturing method thereof. Background technique [0002] According to different touch positions, the touch panel can be divided into two types: an external type and a built-in type. The built-in type means that the touch electrodes are fabricated in the array substrate. The built-in touch panel has the advantages of thinner thickness and lighter weight, so it is widely used and gradually replaces the plug-in touch panel. According to different touch principles, touch panels are divided into self-capacitive touch panels and mutual-capacitance touch panels. The touch electrode of the existing touch panel is divided into several independent touch electrode blocks, and is connected to the integrated circuit by the touch signal transmission line, and the touch signal transmission line is connected with the touch electrode b...
