    摘要： An array substrate, a driving method, an organic light emitting display panel and a display device. The array substrate includes a plurality of light emitting devices and pixel circuits connected with the light emitting devices, both located in a display area as well as a plurality of voltage control circuits located in a non-display area, wherein at least two of the pixel circuits in one row share one of the voltage control circuits, so that the structure of each pixel circuit in the display area can be simplified, the area occupied by the pixel circuits in the display area can be reduced, and furthermore, more pixel circuits and light emitting devices can be arranged in the display area to obtain an organic light emitting display panel with a high PPI. Moreover, due to the control of the voltage control circuits over reset control signals, initialization signals are output to first electrodes of driving transistors to control the corresponding light emitting devices to be reset, so that influences of voltages loaded on the light emitting devices during previous-frame light emission on next-frame light emission can be avoided, and furthermore, the phenomenon of residual shadows is relieved.

    摘要： The present disclosure, pertaining to the field of display, provides a pixel circuit and a drive method thereof, a display substrate, and a display device. The pixel circuit includes a gate signal terminal, a data signal terminal, a switch signal terminal and a voltage division control signal terminal. The pixel circuit further includes a current source sub-circuit (11) and a voltage divider sub-circuit (12).

The voltage divider sub-circuit (12) is configured to regulate an equivalent resistance value of the voltage divider sub-circuit (12) in an output path of the drive current based on a signal received by the voltage division control signal terminal. The present disclosure facilitates high-contrast display of the OLED display in a low-voltage process.

    摘要： A temperature compensation method for a display panel, a display panel, and an electronic device are disclosed. The display panel includes a pixel array, the pixel array includes a pixel unit, and the pixel unit includes a first voltage terminal and a second voltage terminal. The first voltage terminal is configured to receive a first power supply voltage, and the second voltage terminal is configured to receive a second power supply voltage. The pixel unit is configured to drive the light emitting element to emit light based on the first power supply voltage and the second power supply voltage that are received. The temperature compensation method for the display panel includes: setting a voltage difference between the second power supply voltage and the first power supply voltage as a first voltage difference, so as to enable a temperature of the display panel to rise, and setting the voltage difference between the second power supply voltage and the first power supply voltage as a second voltage difference after the temperature of the display panel rises. The first voltage difference is greater than the second voltage difference. The temperature compensation method for the display panel can effectively shorten the temperature rise time of the display panel, so that the temperature of the display panel reaches a stable temperature rapidly.
