Abstract
An OLED display panel is provided. The OLED display panel includes a plurality of sub-pixels arranged in an array and a plurality of pixel drive circuits for driving the sub-pixels. At least one of the pixel drive circuits comprises a reset module, a data signal input module, a storage module, a light emitting device, and a drive module. The drive module drives a first light emitting device and a second light emitting device to emit light in a first display stage, and drives the first light emitting device to emit light in a second display stage, whereas the second light emitting device does not emit light.
