Claim 15:
16. A display device, comprising an OLED display panel and a drive chip, wherein the OLED display panel comprises a plurality of sub-pixels arranged in an array and a plurality of pixel drive circuits for driving the sub-pixels, wherein each of at least one of the pixel drive circuits comprises:
a reset module configured to reset a potential at a first point under control of a first scan signal;
a data signal input module connected to the reset module through the first point, and configured to input a data signal to the first point under control of a second scan signal;
a storage module connected to the data signal input module through the first point, connected to a first power potential signal line through a second point, and configured to store a voltage of the data signal;
a light emitting device comprising a first light emitting device and a second light emitting device;
a drive module, wherein a first input end of the drive module is connected to the first power potential signal line, a second input end of the drive module is connected to the first point, and a third input end of the drive module is connected to the data signal input module through a third point, a fourth input end of the drive module is connected to the data signal input module through a fourth point, and an output end of the drive module is connected to both the first light emitting device and the second light emitting device, and is configured to drive the first light emitting device and the second light emitting device to emit light in a first display stage under control of a first light emitting control signal, a second light emitting control signal, and a first point potential, and to drive the first light emitting device to emit light, but not to drive the second light emitting device to emit light in a second display stage,
wherein the OLED display panel comprises:
a substrate;
a pixel electrode layer formed on an upper surface of the substrate, and patterned to form a plurality of pixel electrodes;
a pixel definition layer formed on a side of the pixel electrode layer away from the substrate, and patterned to form a plurality of opening areas, wherein the opening areas have one-to-one correspondence to the pixel electrodes,

wherein in each of at least one of the opening areas, the pixel electrode comprises a first sub-pixel electrode and a second sub-pixel electrode that are not in contact with each other.
