Problems solved by technology

However, due to various non-ideal factors, such as the fringing effect of the sensing electrodes, etc., there will be errors between the coordinates calculated by the touch panel and the real coordinates of the user's touch position; if the error is too large, It is impossible to correctly analyze the touch that the user intends to perform

Embodiment B

[0070] figure 1 Two embodiments B R[i]a and BR[i]b of the sensing electrode group BR[i] are shown. The sensing electrode group BR[i]a includes sensing electrodes U[i] and D[i], which are upper electrodes and lower electrodes respectively, separated by an insulating gap GPi with a width dxx. In order to analyze the y-coordinate of the touch position, the cross-sectional width of the sensing electrode D[i] along the x-direction will change along the y-axis; for example, the x-sectional width of the sensing electrode D[i] at the y-coordinate YD is the width dx1, and when the y coordinate YU is reached, the x-axis section width is reduced to a narrower width dxs. Similarly, the cross-sectional width of the sensing electrode U[i] along the x-direction also changes along the y-axis, for example, the cross-sectional width at the y-coordinate YD is narrower, and the cross-sectional width at the y-coordinate YU is wider. Another embodiment of the sensing electrode group BR[i] BR[i]b ...

Abstract

The invention relates to a method for correcting touch control coordinates and a related system. An original x coordinate and an original y coordinate are corrected according to a total sensing value, the original x coordinate and the original y coordinate which are provided by sensing touch control of a touch control panel. The method for correcting the touch control coordinates comprises the steps of providing an estimation x axis correcting value according to the original x value and the total sensing value, generating a correcting x coordinate according to the estimation x axis correcting value and the original x coordinate, and providing a correcting y coordinate according to the original x coordinate, the correcting x coordinate and the total sensing value.

Description

technical field [0001] The present invention relates to a method and a related system for correcting touch coordinates, and in particular to a method and method for correcting x-coordinates based on the total sensing value of sensing electrodes and original x-coordinates and then correcting y-coordinates accordingly. related systems. Background technique [0002] Touch panels, such as capacitive touch panels, can provide users with a friendly and intuitive operation interface, and have been widely used in various consumer electronic devices, portable devices and handheld devices, such as remote controls, mobile phones, Digital cameras and camcorders, tablets, touch screens, and more. The capacitive touch panel uses multiple sensing electrodes to sense the capacitance change before and after the user touches, and obtains a set of coordinates (including x-coordinates and y-coordinates), representing the user's position on the touch panel. Touch location. However, due to var...
