Embodiment Construction

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] As described in the background art, nowadays display panels tend to be thinner and lighter, and the thickness of the display panels is getting thinner and thinner. The flexible display panels derived therefrom are 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, embodiments of the present invention provide a display panel and...

Abstract

The present invention provides a display panel and a display device. By setting the effective area of ​​the driving sub-touch electrodes to be larger than the effective area of ​​the inductive sub-touch electrodes, the effective area of ​​the inductive sub-touch electrodes can be reduced due to the small effective area of ​​the inductive sub-touch electrodes. The inductive coupling capacitance formed between the touch medium and the inductive sub-touch electrodes reduces the coupling signal coupled to the inductive sub-touch electrodes through the inductive coupling capacitance, thereby reducing the effect of the coupling signal on the inductive sub-touch electrodes and the driver. The influence of the interactive capacitance formed between the touch electrodes ensures that the variation of the interactive capacitance is increased, the touch effect of the display panel is high, and the signal-to-noise ratio of the display panel is improved at the same time. In addition, reducing the effective area of ​​the sensor sub-touch electrodes can reduce the charging time for the mutual capacitance formed between the driver sub-touch electrodes and the sensor sub-touch electrodes, thereby increasing the driving frequency of the driver sub-touch electrodes. To achieve the purpose of improving the touch reporting rate.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] The touch display panel is a display panel that integrates touch 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 user-friendly 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 lighter, and the thickness of the display panel is getting thinner and thinner. The flexible display panel derived therefrom is one of the inevitable key development directions in the future. However, the touch effect of the existing display panel is poor. SUMMARY OF THE INVENTION [0003] In view of this, the present ...
