Problems solved by technology

[0004] In the existing touch display panel, the TX electrode is unilaterally driven by the driver IC located on one side of the Y direction. The farther away from the IC, the more attenuated the signal of the TX electrode, which causes some problems. For example, in the display stage, the common electrode VCOM is uneven; in the touch detection stage, the signal volume of the TX electrode is uneven, resulting in inconsistent touch performance between the near end of the TX electrode close to the IC and the far end far away from the IC.

Abstract

The invention relates to a touch display panel and a touch display device thereof. The touch display panel adds a touch drive circuit at one side of a touch drive electrode far away from a driver IV, the touch drive electrode can be simultaneously driven by driver IC and the touch drive circuit at two sides of an electrode extension direction, thereby realizing the dual-side driving and providing stronger driving force of the touch drive electrode. On the one hand, the public electrode potential uniformity on the touch drive electrode is guaranteed in the display stage, and on the other hand, the more uniformity of the semaphore on the touch drive electrode is guaranteed at the touch stage, and the consistency of the entire touch performance is guaranteed.

Description

technical field [0001] The invention relates to the field of display technology, and relates to a touch display panel and a touch display device thereof. Background technique [0002] With the development of display technology, more and more display panels are integrated with touch functions to bring convenience to users. [0003] At present, in order to reduce the thickness of the display panel and realize the touch function, the touch structure is usually integrated into the display panel. For example, the existing mutual capacitance hybrid touch structure (hybrid in-cell), such as figure 1 As shown, the structure schematic diagram of the touch display panel in the prior art, the touch driving electrodes (also known as TX electrodes, figure 1 marked TX) is arranged on the inner side of the array substrate 1' (TFT substrate), which is divided into several along the direction of the data line ( figure 1 The strip-shaped sub-electrodes arranged in parallel in the Y directi...
