Touch panel with reduced electromagnetic interference
View Patent ↗Provided is a touch panel. The touch panel includes a first substrate and a second substrate disposed opposite to each other; a plurality of stacks separated by a pixel definition layer and each including an anode block and an organic light emitting block; a plurality of cathodes; a plurality of strip-shaped first touch electrodes arranged in a first direction and each extending in a second direction; and a plurality of strip-shaped second touch electrodes arranged in the second direction and each extending in the first direction. The first touch electrodes may arranged on the same layer with the anodes or arranged on the same layer with the cathodes, and are directly on the pixel definition layer. A projection of the strip-shaped first touch electrode is located between projections of two adjacent cathodes.
