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 present invention discloses a touch panel, a touch device and a touch position detection method. The touch panel includes: a plurality of touch electrode blocks; a plurality of auxiliary touch electrodes; the touch panel also includes a module Group setting area, the plurality of touch electrode blocks and the module setting area do not overlap; the plurality of auxiliary touch electrodes are located between the touch electrode block and the module setting area and along the The edge setting of the module setting area; the touch position calculation unit, the touch position calculation unit is used according to the sensing amount of the touch electrode block, the sensing amount of the auxiliary touch electrode, the auxiliary touch electrode The gain value of the touch electrode block, the geometric center of the touch electrode block and the geometric center of the auxiliary touch electrode determine the touch position of the touch object; wherein, the area of ​​the auxiliary touch electrode is smaller than the area of ​​the touch electrode block . The present invention can avoid the problem of inaccurate calculation of the touch position near the module setting area.

Description

technical field [0001] The 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, 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 viewing area of ​​a display device to the total area of ​​the plane on which 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, thereby reducing the area occupied by the non-display area. For this, a hole-digging area can be set within the range surrounded by the display area to convert the original The modules arranged in the frame area (for example: the front camera on the mobile phone, the front flash, the earpiece, etc.) are arranged in the hole-diggin...
