Abstract
A display panel and a display terminal are provided. The display panel includes a base substrate and a plurality of sub-pixels. The sub-pixels include a sub-pixel driving circuit and a light emitting device. The sub-pixel driving circuit includes a detection unit, a first light emitting control unit, and a second light emitting control unit. By detecting a potential of a second node, the light emitting device does not emit light abnormally, there is no need to perform dark line processing on the sub-pixels in a current row, and influence of dark lines is eliminated.
