Claim:
1. A pixel circuit, comprising a plurality of pixels, each of the plurality of pixels includes a blue sub-pixel and a driving module, wherein the blue sub-pixel comprises N blue organic light-emitting diodes (OLEDs), and N is a positive integer greater than 1, the driving module is configured to drive the N blue OLEDs in a time division manner, wherein the driving module comprises a driver circuit for driving the blue sub-pixel in a time division manner, and the driver circuit includes an input transistor and N driving units, a gate electrode of the input transistor is connected to a scanning line, a first electrode of the input transistor is connected to the N driving units, and a second electrode of the input transistor is connected to a data line, a cathode of each of the N blue OLEDs is connected to a first level output end, and an anode thereof is connected to a level output and via the driving unit, and the driving unit is configured to, when an absolute value of a voltage difference between a current level output end connected to the driving unit and the first level output end is greater than an absolute value of a turn-on voltage of the blue OLED connected to the driving unit and when the level output ends other than the current level output end and the first level output end are floating, drive the blue OLED to emit light.
