Abstract

The invention discloses a pixel driving circuit, a control method thereof, a display panel and electronic equipment, and the pixel driving circuit comprises a driving unit which is connected with a light emitting device and a first voltage end; a storage unit which is connected with the driving unit; a discharge control unit which is connected with the storage unit, the first voltage end and the driving unit and used for controlling voltage values at the two ends of the storage unit and controlling the driving unit to discharge to the first voltage end; a storage control unit which is connected with the driving unit and the storage unit and used for controlling the storage unit to store the voltage generated after the driving unit discharges; And a data writing unit which is connected withthe storage unit, the data signal input end, the first control signal end and the discharge control unit and is used for writing the data voltage into the storage unit under the control of a first control signal input by the first control signal end and controlling the driving unit to be conducted so as to drive the light emitting device to emit light. The circuit provided by the invention can improve the light-emitting effect of the light-emitting device and prolong the service life of the light-emitting device.

Description

technical field [0001] The present invention relates to the technical field of display control, in particular to a pixel driving circuit, a display panel, an electronic device and a control method of the pixel driving circuit. Background technique [0002] In an OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display, since a current drives the OLED to emit light, the current stability of the OLED is very important and directly affects the brightness of the OLED. The OLED current is generally related to the voltage driving the TFT (Thin Film Transistor, thin film transistor), and the TFT of the a-Si (Amorphous Silicon, amorphous silicon) process has the problem of threshold voltage drift, that is, when the voltage is applied to the gate source, The current of the TFT will gradually decay and the threshold voltage will increase. This problem will directly affect the brightness and lifetime of OLED. Contents of the invention [0003] The present invention...
