Abstract
The present invention provides a display panel and an electronic device. A gate driver on array (GOA) circuit in the display panel includes a plurality of cascaded GOA units. The GOA units include a plurality of effective GOA units and 2m redundant GOA units arranged in sequence. The plurality of effective GOA units forms a plurality of effective GOA modules that are arranged in sequence. In the effective GOA module, the 2m effective GOA units are sequentially connected to the 2m clock signal lines, and the 2m redundant GOA units are sequentially connected to the 2m clock signal lines. The display panel of the present invention has no periodic dark lines at low gray levels.
