Touch component and touch display device

Abstract

The present application provides a touch component and a touch display device, the touch component includes a touch layer, the touch layer includes a plurality of touch units, each touch unit includes: a first electrode arranged along a first direction; and , the second electrode arranged along the second direction, the first electrode is electrically insulated from the second electrode; wherein, at the intersection position near the first electrode and the second electrode, the first electrode includes at least one recessed part, and the second electrode The electrode includes at least one raised portion cooperating with the indented portion. By setting the indented part on the first electrode and the raised part on the second electrode, it is ensured that the impedance of the first electrode close to the crossing position of the first electrode and the second electrode does not increase, and at the same time, the resistance of the second electrode is reduced. Impedance close to the intersection of the first electrode and the second electrode, thereby reducing the resistance-capacitance load of the second electrode, reducing the time required for the touch display device to scan, thereby increasing the reporting rate.

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] Such as 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 ...

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.
