Abstract
A display panel includes a plurality of sub-pixels and a plurality of data lines, and a detection circuit. The data lines include at least one first data line. The detection circuit includes a first detection signal line, a detection control signal line, and at least one first switch. The first detection signal line and the detection control signal line detour along an edge of the active area. The first detection signal line is configured to transmit a detection signal, and the detection control signal line is configured to transmit a detection control signal. The first switch is electrically connected to the first detection signal line, the detection control signal line, and the at least one first data line, and is configured to close a line between the first detection signal line and the first data line, in response to the detection control signal.
