    Abstract: A pixel circuit includes a light-emitting device, a reset circuit, a write circuit, a compensation circuit, a light emission control circuit, and a drive circuit. The compensation circuit is configured to selectively transfer an uncompensated reference voltage or a compensated reference voltage to a third node, the compensated reference voltage being determined by the uncompensated reference voltage and a compensation voltage, the compensation voltage being related to a rated value of a power supply voltage. The light emission control circuit is configured to transfer a voltage at the third node to a first node to cause a change in voltage at the second node. The drive circuit is configured to control a magnitude of a drive current flowing through the light-emitting device based on the voltage at the second node and the power supply voltage.

    Abstract: An organic light emitting diode display pixel, a display panel and a display device are provided. The organic light emitting diode display pixel comprises a red light emitting device, a green light emitting device and a blue light emitting device arranged side by side and disposed oblique with respect to a border of the pixel. The red light emitting device and the green light emitting device are located on both sides of the blue light emitting device, which has a length larger than those of the red one and the green one. The display pixel can prolong the service life of a display panel without reducing the total aperture ratio of pixels.
