Abstract

The present disclosure relates to the field of display technology, and in particular, to a pixel driving circuit, a pixel driving method, and a display device. The pixel driving circuit includes first to fifth switching elements, a driving transistor, a first storage capacitor and a second storage capacitor. The pixel driving circuit can eliminate the influence of the threshold voltage of the driving transistor, the voltage drop of the wire impedance, and the aging of the electroluminescent element on the driving current during the working process, so as to ensure that the driving current output by each pixel driving circuit is consistent, thereby ensuring that each pixel Displays the uniformity of brightness.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a pixel driving circuit, a pixel driving method, and a display device. Background technique [0002] Organic light emitting diode (Organic Light Emitting Diode, OLED), as a current-mode light-emitting device, has been increasingly used because of its characteristics of self-luminescence, fast response, wide viewing angle and can be fabricated on flexible substrates. In the field of high-performance display. OLED display devices can be classified into PMOLED (PassiveMatrix Driving OLED, passive matrix driving organic light emitting diode) and AMOLED (Active Matrix Driving OLED, active matrix driving organic light emitting diode) according to different driving methods. Due to the advantages of AMOLED displays such as low manufacturing cost, high response speed, power saving, DC drive for portable devices, and wide operating temperature range, AMOLED has attracted in...
