Abstract:
A display panel includes a plurality of pixel circuits. Each of pixel circuits comprises an emission unit including an organic light emitting diode, a pixel driving unit configured to drive an emission unit based on a scan signal and a data signal, and a switch unit configured to control an electrical connection between an emission unit and a pixel driving unit based on an emission signal. A first parasitic capacitance between an emission unit included in a first pixel circuit of pixel circuits and a pixel driving unit included in a first pixel circuit is smaller than a second parasitic capacitance between an emission unit included in a first pixel circuit and a pixel driving unit included in a second pixel circuit of pixel circuits adjacent to a first pixel circuit.
