Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] As mentioned in the background art, the current display panel tends to be thinner and thinner, and the thickness of the display panel is getting thinner and thinner. The flexible display panel derived from this is one of the inevitable key development directions in the future. However, the touch effect of the existing display panel is poor.

[0041] Based on this, the embodiments of the present invention provide a display panel and a display device, whi...

Abstract

The invention discloses a display panel and a display device. The effective area of a driving sub touch electrode is set to be larger than the effective area of an inductor sub touch electrode; and since the effective area of the inductor sub touch electrode is small, inductive coupling capacitance formed between a touch medium and the inductor sub touch electrode can be reduced, a coupling signal coupled to the inductor sub touch electrode through an inductive coupling capacitor is reduced, the influence of the coupling signal on an interaction capacitance formed between the inductor sub touch electrode and the driving sub touch electrode is reduced, the change quantity of the interaction capacitance is improved, the touch effect of the display panel is relatively high, and meanwhile, the signal-to-noise ratio of the display panel is improved. Besides, by reducing the effective area of the inductor sub touch electrode, the charging time for the interaction capacitance formed between the inductor sub touch electrode and the driving sub touch electrode can be shortened, the driving frequency of the driving sub touch electrode can be improved, and the purpose of improving the touch control point reporting rate is achieved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background technique [0002] The touch display panel is a display panel that integrates touch control and display, so that the display panel has a touch function. Generally, a touch display panel can provide a human-computer interaction interface and allow input through a touch medium such as a finger, which is more direct and humanized in use. With the development of display technology, touch display panels are increasingly used in various display devices. Nowadays, the display panel tends to be thinner and thinner, and the thickness of the display panel is getting thinner and thinner. The flexible display panel derived from this is one of the inevitable key development directions in the future. However, the touch effect of the existing display panel is poor. Contents of the invention [0003] In view of this, the pre...
