Abstract

The invention discloses a display panel and a display device. The display panel includes a first substrate and a second substrate opposite to the first substrate; the first substrate includes a plurality of touch electrodes distributed in an array; the second substrate includes A plurality of auxiliary touch electrodes, each of which overlaps the projections of a part of two adjacent touch electrodes in a direction perpendicular to the second substrate. Wherein, the overlapping portions of the auxiliary touch electrodes and the touch electrodes have the same shape. In the display panel of the present invention, when a touch operation occurs, a coupling capacitance is formed between the touch medium and the touch auxiliary electrode, and a coupling capacitance is further formed between the touch auxiliary electrode and the touch electrode, which is equivalent to shortening the distance between the touch medium and the touch control electrode. The vertical distance between the touch electrodes, and each touch operation can correspond to more touch electrodes, which reduces the difficulty of judging the touch position and the accuracy requirements of the touch operation.

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 technology, touch panels (Touch Panel) 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. like figure 1 As shown, when the finger touches the capacitive touch screen, due to the electric...
