Problems solved by technology

[0005] One disadvantage of existing touch panels is that when a contact object draws a line back and forth quickly, due to the geometric relationship of the sensing electrodes, the proximity point sensed by the sensing device will appear ripple or wave-like instead of the contact object. moving straight line

Abstract

The embodiment of the invention provides a sensing method for a sensing electrode, wherein the sensing electrode comprises a plurality of electrodes of a plurality of groups. The sensing method comprises the steps that the plurality of electrodes of each group are scanned on the basis of a first scanning sequence; the plurality of electrodes of the each group are scanned on the basis of a second scanning sequence, wherein the first scanning sequence is different from the second scanning sequence.

Description

technical field [0001] The present invention relates to a touch panel, in particular to a sensing device and a sensing method for sensing electrodes on the touch panel. Background technique [0002] Touch panel is a huge industry, and all kinds of electronic products use touch panel as an important input and output device of human-machine interface. The performance of the touch panel depends on the sensing electrodes and the logic circuit connected to the sensing electrodes. The design and quality of the sensing electrodes will affect the performance of the touch panel. [0003] Generally, the sensing electrodes of the touch panel are formed on a transparent substrate. The light emitted by the display device can be displayed to the user through the transparent substrate. The sensing electrodes formed on the transparent substrate include a plurality of electrodes, and the electrodes are connected to a logic circuit through a plurality of wires. [0004] As the resolution ...
