Touch control assembly and touch display device

Abstract

The invention provides a touch control assembly and a touch control display device. The touch control assembly comprises a touch control layer; the touch control layer comprises a plurality of touch control units; each touch control unit comprises a first electrode arranged along a first direction, and a second electrode arranged in the second direction, wherein the first electrode is electricallyinsulated from the second electrode. At the position close to the intersection of the first electrode and the second electrode, the first electrode comprises at least one concave part, and the secondelectrode comprises at least one convex part matched with the concave part. The concave part is arranged on each first electrode, and the convex part is arranged on each second electrode; therefore,the impedance of the first electrode at the position close to the intersection of the first electrode and the second electrode is not increased, and the impedance of the second electrode at the position close to the intersection of the first electrode and the second electrode is reduced, so that the resistance-capacitance load of the second electrode is reduced, the scanning time of the touch display device is shortened, and the point reporting rate is increased.

Description

technical field [0001] The present application relates to the field of touch technology, in particular to a touch component and 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] like figure 1 As shown, it is a schematic diagram of the touch electrode of the traditional flexible active matrix organic light emitting diode (Active Metrix OrganicLight Emitting Diode, AMOLED) touch oncell display screen. The touch electrode includes a driving electrode Tx and a sensing electrode Rx. The driving electrode Tx and the sensing electrode Rx are arranged on the same layer and are insulated from each other. The driving electrode Tx and the sensing ele...

AI Technical Summary

Problems solved by technology

Since the driving electrode Tx and the sensing electrode Rx are diamond-shaped, the impedance load of the driving electrode Tx and the sensing electrode Rx is relatively large, resulting in an increase in the scanning time of the touch control, resulting in a decrease in the report rate of the touch control, which is not conducive to satisfying the touch report point demand for rate increases

[0004] Therefore, it is necessary to propose a technical solution to solve the problem that the touch report rate is reduced due to the large impedance load when the driving electrodes and sensing electrodes are diamond-shaped.
