Abstract
A display panel, a touch test method, and an electronic device are provided. The display panel includes a substrate, touch test terminals, a multiplexing circuit, touch units, and a touch display chip. Before the touch display chip is bonded to the display panel, the multiplexing circuit is configured to reduce a number of traces of the touch units connected to the touch test terminals to facilitate execution of a touch test. In addition, a number of the touch test terminals used is reduced, which can save space occupied by a frame.
