Embodiment Construction

[0046] The present invention 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 invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0047] As mentioned in the background, multi-screen touch display devices in the prior art usually use multiple driving chips. figure 1 It is a schematic structural diagram of a folding screen in the prior art. Taking a folding dual-screen display device as an example, it includes a main screen and a secondary screen, wherein the main screen and the secondary screen correspond to a driver chip, and each driver chip works independently. When the display device is in the folded state, the display area of ​​the secon...

Abstract

The embodiment of the invention discloses a touch display panel and a driving method thereof. The touch display panel comprises: a driving chip; a plurality of first touch signal lines, a plurality of second touch signal lines,..., and a plurality of nth touch signal lines, wherein the at least one first touch signal line, the at least one second touch signal line,... and the at least one nth touch signal line are connected with the same output end of the driving chip, and the driving chip is used for controlling the on-off states of the first switch, the second switch... and the nth switch according to the use states of the n touch areas so as to output touch driving signals to the n touch areas. According to the technical scheme provided by the embodiment of the invention, the touch electrodes of the n touch areas share the same driving chip, so that one driving chip controls the n touch areas, the number of the driving chips is reduced, and the product cost is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of touch display, and in particular, to a touch display panel and a driving method thereof. Background technique [0002] With the continuous development of display technology, people's demand for touch display devices is becoming more and more diversified, and electronic products such as mobile phones and tablets are developing towards large screens, curved screens and multi-screen displays. [0003] The multi-screen touch display products in the prior art need to use multiple touch chips, and the production cost is relatively high. Contents of the invention [0004] Embodiments of the present invention provide a touch display panel and a driving method thereof, so as to simultaneously control multiple touch display areas by using one driving chip. [0005] In the first aspect, an embodiment of the present invention provides a touch display panel. The touch display panel is divided ...
