Problems solved by technology

For the known architecture that uses Tx and Rx interleaving and bridging design, the two adjacent Tx and Rx are extremely close to each other, so there is a large Cm value, so the touch refresh rate is low and cannot be effectively improved.

Abstract

The invention discloses a touch sensing layer and a touch panel. The touch sensing layer comprises a first axial conductive unit, a second axial conductive unit and at least one virtual electrode. The first shaft conductive unit substantially extends along a first axial direction. The second axial conductive unit substantially extends along a second axial direction and comprises two conductive electrodes and a conductive bridge. The two conductive electrodes are located on the two opposite sides of the first shaft conductive unit respectively. The conductive bridge spans the first shaft conductive unit and is connected with the two conductive electrodes. At least one part of the virtual electrode is located in a gap formed between the first shaft conductive unit and one of the two conductive electrodes. Therefore, the touch refresh rate of the touch panel can be effectively improved.

Description

technical field [0001] The invention relates to a touch sensing layer and a touch panel. Background technique [0002] With the continuous expansion of size and the trend of being indispensable in game applications, the most critical change of the touch display device is the continuous improvement of the display refresh rate of the display module. For example, the display refresh rate of the display module of the mobile phone will be increased from 120Hz to 180Hz, or even a higher order of 240Hz. Correspondingly, the touch refresh rate of the touch module is also required to increase synchronously. [0003] As far as the principle of the touch refresh rate is concerned, in the touch module, the driving speed is mainly considered based on two adjacent mutual capacitance (capacity mutual, Cm) values ​​between the driving electrode (Tx) and the receiving electrode (Rx). More specifically, the speed of driving each electrode scan is determined by the charging and discharging s...
