Embodiment Construction

[0092] Embodiments of the disclosed document will be described below with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar elements or method flows.

[0093] figure 1 It is a simplified functional block diagram of the electronic device 100 according to an embodiment of the disclosure. The electronic device 100 has a self-capacitive touch function, and includes a control circuit 101 , a plurality of wires 103 and a plurality of touch structures 10_1 - 10 — n arranged along the X-axis. The respective capacitance values ​​of the touch structures 10_1 - 10 — n will change according to the touch input, wherein the touch input may be that the user approaches or approaches the electronic device 100 with a finger. The capacitance variation of the touch structures 10_1˜10_n is transmitted to the control circuit 101 through the wiring 103, and the control circuit 101 is used to calculate the position of the touch input ...

Abstract

The invention discloses an electronic device with a touch function and a touch sensing method. The electronic device with the touch function comprises a plurality of touch structures arranged along an X axis. Each touch structure comprises a first electrode, a second electrode and a third electrode. The first electrode includes an upper half electrode and a lower half electrode coupled to each other. The upper half electrode and the lower half electrode extend toward each other along the Y-axis and are substantially triangular, and the X-axis is substantially orthogonal to the Y-axis. The second electrode is substantially triangular, and a first side and a second side of the second electrode face the lower half electrode and the upper half electrode, respectively. The third electrode is located between the lower half electrode and the first side of the second electrode, and the third electrode is substantially in a long strip shape. According to the electronic device, the number of wires needed by the touch electrodes for receiving and outputting signals can be greatly reduced.

Description

technical field [0001] The disclosed document relates to an electronic device with touch function and a touch sensing method thereof, especially to an embedded touch electronic device and a touch sensing method thereof. Background technique [0002] The embedded touch technology can manufacture the touch module inside the display, so that the whole device has the advantages of thinner, lighter and higher brightness. The operating principle of the common in-cell touch display on the market is to perform self-capacitive touch sensing through multiple rectangular touch electrodes arranged in a matrix inside it, and each touch electrode requires a separate wiring To transmit the sensing result to the touch chip. However, as the demand for touch resolution gradually increases, the number of channels of a common touch chip is not enough to support this design method, and the touch electrodes are easily shorted to each other due to a large number of dense traces.
