Abstract

The embodiment of the invention discloses a display panel and electronic equipment. The display panel comprises a common electrode layer, a plurality of first touch routes and a plurality of second touch routes, wherein the common electrode layer is segmented into a plurality of first electrodes; a plurality of openings are formed in the first electrodes; a second electrode arranged on the same layer of the corresponding first electrode is arranged in each opening; the plurality of second electrodes are arranged in an array from; an annular closed slit is formed between each first electrode and any one second electrode arranged in the opening of the corresponding first electrode; at least one first touch route is correspondingly and electrically connected with one first electrode; the first touch routes extend in the second direction and are overlapped with the annular closed slits in the direction perpendicular to the display panel; at least one second touch route is correspondingly and electrically connected with a column of second electrodes. According to the display panel provided by the embodiment of the invention, touch detection precision is improved, and touch detection of the display panels with narrow frames and large-medium sizes is realized.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel and electronic equipment. Background technique [0002] The development trend of the existing display panel is to integrate the touch panel component and the liquid crystal panel, thereby realizing thinning and lightening of the display panel. The integrated capacitive touch display panel includes self-capacitance and mutual capacitance. [0003] In the self-capacitive touch display panel, the common electrode layer is usually divided into a plurality of common electrode blocks arranged in an array, and the common electrode blocks are multiplexed as touch electrodes in the touch stage. Such as Figure 1A As shown, each touch electrode 10 is electrically connected to the driving chip IC through a corresponding touch wire 11 . For the touch electrodes 10 close to the IC end, the number of overlapping touch traces 11 is large, so that the closer th...
