Abstract

The present disclosure provides an integrated touch control display panel. The integrated touch control display panel includes a plurality of stripe-shaped common electrodes sequentially arranged in a first direction and extending in a second direction intersecting with the first direction. The stripe-shaped common electrodes operate as touch control driving electrodes during a touch control phase. At least two stripe-shaped common electrodes have an equal on-state resistance in the second direction and an equal aggregated parasitic capacitance during a touch control phase.
