Display panel and display device with auxiliary touch electrode
A display panel and a display device are disclosed. The display includes a first substrate and a second substrate disposed opposite to the first substrate. The first substrate includes a plurality of touch electrodes arranged in an array. The second substrate includes a plurality of auxiliary touch electrodes, and a projection of each of the plurality of auxiliary touch electrodes partly overlaps with projections of two adjacent touch electrodes of the plurality of touch electrodes in a direction perpendicular to the second substrate. In the touch operation, a coupling capacitor is formed between the touch medium and the auxiliary touch electrode, another coupling capacitor is formed between the auxiliary touch electrode and the touch electrode, so that more touch electrodes are involved in each touch operation, thus reducing the difficulty of determining the touch position and the precision requirement for the touch operation.
