Problems solved by technology

At present, the calculation of touch position is generally based on the sensing amount of each touch electrode and the geometric center of each touch electrode. However, when using the existing touch position calculation method to detect the touch position near the hole-digging area, it is easy Causes the problem of inaccurate touch point reporting. There is a large error between the actual position of the touch and the calculated position, which leads to misjudgment when the finger clicks near the hole-digging area

Abstract

The embodiment of the invention discloses a touch panel, a touch device and a touch position detection method. The touch panel comprises a plurality of touch electrode blocks; a plurality of auxiliarytouch electrodes; a module set area, wherein the touch electrode blocks are not overlapped with the module set area, and The plurality of auxiliary touch electrodes are positioned between the touch electrode block and the module setting area and are arranged along the edge of the module setting area; The touch position calculating unit which is used for determining the touch position of a touch object according to the induction quantity of the touch electrode block, the induction quantity of the auxiliary touch electrode, the gain value of the auxiliary touch electrode, the geometric center of the touch electrode block and the geometric center of the auxiliary touch electrode, Wherein the area of the auxiliary touch electrode is smaller than that of the touch electrode block. According tothe invention, the problem of inaccurate calculation of the touch position near the module setting area can be avoided.

Description

Technical field [0001] The present invention relates to display technology, in particular to a touch panel, a touch device and a touch position detection method. Background technique [0002] With the development of display technology, in order to improve user experience, a high screen-to-body ratio has gradually become an important development direction of display devices. The screen-to-body ratio can be understood as the ratio of the visible area of ​​the display device to the total area of ​​the plane where it is located. In order to increase the screen-to-body ratio, it is necessary to reduce the area occupied by the frame area of ​​the display device so as to reduce the area occupied by the non-display area. For this, a digging area can be set in the range enclosed by the display area to save the original Modules arranged in the frame area (for example: front camera, front flash, earpiece, etc. on the mobile phone) are arranged in the digging area. For the display panel wi...
