Problems solved by technology
Usually, the attenuation of the touch scanning signal caused by the connecting wires with different lengths is different, which makes the touch scanning signals obtained by the touch driving electrodes connected with the connecting wires with different lengths different, which further causes the touch screen to receive touch signals from different positions. The accuracy of the touch signal corresponding to the control drive electrode is different, so that the sensitivity of receiving the touch signal at different positions on the touch screen is different.

The invention discloses a touch display panel and a driving method thereof, as well as a touch display device. The touch display panel comprises a plurality of touch driving electrode groups arrayed along a first direction, wherein each touch driving electrode group comprises at least one touch driving electrode, and every two adjacent touch driving electrode groups share at least one touch driving electrode; a touch circuit which comprises a plurality of switch groups corresponding to the touch driving electrode groups one to one, wherein each switch group comprises at least one switch electrically connected with each touch driving electrode in the corresponding touch driving electrode group in a one-to-one correspondence manner; a plurality of touch signal lines electrically connected with the switch groups in a one-to-one correspondence manner; and an integrated driving circuit which is electrically connected with the touch signal lines and is used for transmitting touch scanning signals to the touch signal lines. According to the touch display panel, the attenuation and the delay from the integrated driving circuit to a signal on each touch driving electrode group are reduced, so that the sensitivities of the touch display panel at all positions are balanced.
Description
technical field [0001] The present application relates to the field of display technology, in particular to the field of touch display technology, in particular to a touch display panel, a driving method thereof, and a touch display device. Background technique [0002] With the continuous improvement of the application field and technology of touch display technology, more touch driving electrodes can be arranged on the array substrate of the touch display panel, and more touch sensing electrodes can be arranged on the color filter substrate to improve the touch Control the accuracy of the display to sense the touch signal. [0003] As the market's demand for large-size touch screens increases, the size of the array substrate and color filter substrate of the touch screen also increases. The number of touch drive electrodes on the array substrate and the color filter substrate The number of touch sensing electrodes on the surface is also increasing. Each touch driving ele...
