Abstract

The invention discloses an array substrate, a pixel driving circuit and a pixel driving method. The pixel driving circuit comprises a first switching module, a second switching module, a charging module, a driving module and an organic light-emitting diode (OLED), wherein the first switching module is used for outputting a current data signal to the driving module according to a first scanning control signal, the driving module is used for outputting driving current of the OLED to the second switching module according to the current data signal, and the charging module is used for charging theOLED. According to the embodiment of the invention, the charging time is reduced through charging the OLED by a high charging current source, and the final current is enabled to meet the current required by the OLED through circuit operations.

Description

technical field [0001] The invention belongs to the technical field of electronic circuits, and in particular relates to an array substrate, a pixel driving circuit and a pixel driving method. Background technique [0002] As a new generation of display technology, OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display has the advantages of low power consumption, high color gamut, high brightness, high resolution, wide viewing angle, high response speed, etc. application. [0003] figure 1 It is a pixel driving circuit diagram of an OLED display in the prior art, that is, a voltage-driven pixel driving circuit structure composed of two TFTs (Thin Film Transistor, thin film transistor) and a capacitor (ie, a 2T1C driving circuit structure). [0004] Wherein, Gate n is the scan control signal control line of the nth row, VData is the grayscale voltage signal line of the nth column, Vdd is the power supply voltage, and GND is the power supply ground. T1 is...
