Abstract
A display panel includes a pixel structure corresponding to a display area, and a receiver antenna structure disposed on the pixel structure. The receiver antenna structure includes multiple antenna blocks. Each antenna block includes an antenna, and two diodes are connected in parallel to the antenna and disposed in opposite directions. The diodes are connected to two switches provided with two clock pulse signals phase-inversed from each other. For each pixels, the switches alternately turns on and off in consecutive frames, allowing the pixels to be driven in a driving dot inversion driving mode. Further, the scan lines extending and crossing over the antennas may have crossover portions the common electrode, and a width of the crossover portion of each scan line may be adjusted to compensate the loading of the scan line due to crossover areas with the antennas.
