Problems solved by technology

During the touch scan period, the driver chip outputs touch scan signals to the touch drive electrodes step by step. Before all the touch drive electrodes are scanned, the scanned touch drive electrodes cannot be scanned. The control cannot be fully detected, resulting in a low touch report rate

Embodiment Construction

[0033] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only some structures related to the present application are shown in the drawings but not all structures.

[0034] figure 1 It is a timing diagram of touch drive in the prior art, see figure 1 , figure 1 Exemplarily, the n touch driving electrodes are sequentially marked as TX1 to TXn, wherein n is a positive integer. The first effective driving pulse signal applied to the touch driving electrode TXi is marked as Xi. i is a positive integer greater than or equal to 1 and less than or equal to n. In the touch driving period, the first valid driving pulse signal is provided to the n touch driving electrodes one by one...

Abstract

The invention discloses a touch structure, a touch display panel and a driving method. The touch structure comprises a plurality of touch driving electrodes, a plurality of touch sensing electrodes and a plurality of additional touch driving electrodes; the touch driving electrodes, the touch sensing electrodes and the additional touch driving electrodes are insulated from one another; the touch driving electrodes and the additional touch driving electrodes extend in a first direction and are arranged in a second direction; the touch sensing electrodes extend in a second direction and are arranged in the first direction; the first direction intersects with the second direction; the additional touch driving electrodes are in one-to-one correspondence with the touch driving electrodes; the corresponding additional touch driving electrodes are at least partially overlapped with the touch driving electrodes; and in a touch driving period, if a touch operation is detected at a position corresponding to a certain touch driving electrode, a second effective driving pulse signal is applied to the additional touch driving electrode corresponding to the touch driving electrode after a firsteffective driving pulse signal is ended. The touch structure can improve a touch control reporting rate.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a touch structure, a touch display panel and a driving method. Background technique [0002] With the continuous development of display technology, touch screens have become more and more widely used. According to different working principles, touch screens are generally divided into: resistive touch screen, self-capacitive touch screen, mutual capacitive touch screen and infrared touch screen. In the mutual capacitive touch screen, it includes touch driving electrodes and touch sensing electrodes. When the driving signal is input to the touch driving electrodes, the touch sensing electrodes and the touch driving electrodes are coupled to form mutual capacitance, and the finger and the touch driving electrodes A coupling capacitance is formed between them, which causes a change in the output signal of the touch sensing electrode, and based on this, ...
