Abstract
A display panel and driving method, and a display device are provided. The display panel includes a base substrate, and a light adjustment layer and a touch-control layer disposed over the base substrate. The touch-control layer includes a dummy touch-control structure, and the light adjustment layer includes a first structure. At least a portion of the dummy touch-control structure and the first structure have an overlapped region in a direction perpendicular to the base substrate. The dummy touch-control structure includes a first dummy touch-control structure in the overlapped region, and the first dummy touch-control structure is in contact with the first structure. The first structure in a first state has a first light transmittance, the first structure in a second state has a second light transmittance, and the first light transmittance is greater than the second light transmittance.
