Problems solved by technology

In this way, the number of touch scanning signal lines connected between the touch emitting electrodes and the integrated circuit increases accordingly, and the number of touch sensing signal lines connected between the touch sensing electrodes and the integrated circuit also increases accordingly. increase, the space required for the touch scanning signal lines and / or touch sensing signal lines increases, resulting in an increase in the border width of the touch display device, which is contrary to the current development trend of narrow borders of the display device

Abstract

The present application discloses a touch display panel and a touch display device. An embodiment of the touch display panel includes: a first touch electrode array, comprising M first touch electrodes including 1st to Mth first touch electrodes, arranged along a first direction; and a second touch electrode array, comprising N second touch electrodes; each of the first touch electrodes comprising a first connection portion extending along the second direction, and each of the 2nd to Mth first touch electrodes further comprising a plurality of first electrode blocks; and an orthographic projection of each of the first electrode blocks on the second touch electrode array at least partially overlapping at least two second touch electrodes. The embodiment has improved touch detection accuracy.

Description

technical field [0001] The present disclosure generally relates to the field of display technology, and in particular, to a touch display panel and a touch display device. Background technique [0002] The touch display device can detect the coordinate position of the finger in the display screen plane of the touch display device through the touch electrodes, and perform corresponding display according to the coordinate position. [0003] In the current touch display device, the touch function is mainly realized by two touch electrode layers, wherein each touch electrode layer has a plurality of touch electrodes arranged in parallel, and the two layers of touch electrodes are orthogonal to each other. Apply a touch excitation signal to each touch electrode on one of the touch electrode layers. When a human finger touches the screen of the touch display device, the finger forms a coupling capacitance with some touch electrodes on the screen, and from A leakage current flows ...
