Abstract

The invention discloses a display panel and a display device. The display panel comprises a first baseplate and a second baseplate opposite to the first baseplate, wherein the first baseplate comprises a plurality of touch-control electrodes distributed in an array manner; the second baseplate comprises a plurality of touch-control auxiliary electrodes, and each touch-control auxiliary electrode and parts of two adjacent touch-control electrodes are overlapped in a projection manner in the direction perpendicular to the second baseplate, wherein the overlapped parts of the touch-control auxiliary electrode and the touch-control electrodes are the same in shape. When touch operation is generated in the display panel, coupling capacitance is formed between a touch-control medium and the touch-control auxiliary electrodes, further coupling capacitance is formed between the touch-control auxiliary electrodes and the touch-control electrodes, which is equivalent to reduction of the perpendicular distance of the touch-control medium and the touch-control electrodes; one time of touch operation can correspond to more touch-control electrodes, and the touch-control position judgment difficulty and the touch-control operation accuracy requirement are reduced.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a display panel and a display device. Background technique [0002] With the rapid development of display technologies, touch panels (Touch Panels) have gradually spread in people's lives. Compared with traditional displays that can only provide display functions, displays using touch screens can enable information interaction between users and the display control host. Therefore, touch screens can completely or at least partially replace common input devices, making existing displays Not only can display, but also touch control. [0003] Common touch screens are divided into resistive touch screens, capacitive touch screens, electromagnetic touch screens and infrared blocking touch screens. Capacitive touch screens work by using the current induction of the human body. Such as figure 1 As shown, when the finger touches the capacitive touch screen, due to the el...
