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 invention discloses a touch display panel and a touch display apparatus. The touch display panel provided by one embodiment of the invention comprises a first touch electrode array and a second touch electrode array, wherein the first touch electrode array comprises first to Mth first touch electrodes arranged in a first direction; the second touch electrode array comprises first to Nth second touch electrodes arranged in a second direction; each first touch electrode comprises a first connection part extending in the second direction; the second to Mth first touch electrodes further comprise a plurality of first electrode blocks; the first electrode blocks in any first touch electrode of the second to Mth first touch electrodes are formed on the same side of the first connection part of the first touch electrode; and orthographic projection of each first electrode block to the second touch electrode array is at least partially overlapped with at least two second touch electrodes. According to the scheme, the touch detection precision of the touch display panel is improved.

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 ...
