Problems solved by technology

However, the connecting part 2 surrounds a sub-pixel in the direction perpendicular to the extending direction of the connecting part 2, which will cause the impedance of the connecting part 2 to be relatively large.
[0004] Therefore, it is necessary to propose a technical solution to solve the problem of high impedance of the connection part 2 arranged on the same layer as the driving electrode Tx

Embodiment Construction

[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0045] The present application provides a touch display device. The touch display device includes a touch component and a display panel. The touch component is used for generating a corresponding touch control signal based on the touch operation of the user's finger. The display panel is used for image display, and the display panel includes a plurality of sub-pixels. The touch component can be hung outside the display panel or embedded in the display panel. The display panel...

Abstract

The invention provides a touch display device. The touch display device comprises a touch layer and a display panel, the touch layer is located on the light emitting side of the display panel. The display panel comprises a plurality of sub-pixels. The touch layer comprises a plurality of touch units, each touch unit comprises a first electrode electrically connected through a first connecting partin the first direction, the width of the first connecting part in the direction perpendicular to the extending direction of the first connecting part is larger than or equal to the width of three sub-pixels, and the first connecting part and the first electrode are arranged on the same layer. Compared with the prior art, the impedance of the first connecting part is reduced by enabling the firstconnecting part to surround at least three sub-pixels in the direction perpendicular to the extending direction of the first connecting part, so that the resistance-capacitance delay of the first electrode for conducting an electric signal is effectively reduced, the touch scanning frequency is improved, and the touch reporting rate is improved.

Description

technical field [0001] The present application relates to the field of touch technology, in particular to a touch display device. Background technique [0002] Capacitive touch screens are widely used in various electronic interactive scene devices due to their high durability, long life, and support for multi-touch functions. The capacitive touch screen detects the specific position touched by the finger by detecting the change of capacitance at the position touched by the finger. [0003] Such as figure 1 , which is a schematic diagram of a conventional touch electrode. The touch electrodes include driving electrodes Tx and sensing electrodes Rx. Both the driving electrodes Tx and the sensing electrodes Rx are composed of metal wires. Since the subpixels are arranged at an angle of 45 degrees, the driving electrodes Tx and The metal grids of the sensing electrodes Rx are a plurality of diamond-shaped grids composed of metal wires inclined at 45 degrees and 135 degrees, ...
