Abstract

Provided are a display panel, a display device and a compensation method for the display device. The display panel includes an organic light-emitting diode display panel and a liquid crystal display panel, where the organic light-emitting diode display panel in a first display region is configured as a backlight for the liquid crystal display panel. The organic light-emitting diode display panel includes a first array substrate and an organic light-emitting function film. The first array substrate includes a first pixel driving circuit, where the first pixel driving circuit includes a first A-type pixel driving circuit and a first B-type pixel driving circuit, and a density of the first A-type pixel driving circuit is less than a density of the first B-type pixel driving circuit.
