Abstract

The invention discloses an OLED (organic light emitting diode) pixel circuit, which comprises a switch module, a voltage storage module and a load driving module, wherein the switch module is connected between a scanning line Gn and a data line Data and is used for receiving data voltage of the data line Data under the control of the scanning line Gn; the voltage storage module is connected between a scanning line Gn-1 and the switch module and is used for storing the data voltage received by the switch module; and the load driving module is connected to the voltage storage module and an original light emitting diode and is used for receiving the data voltage of a voltage line and for converting the data voltage into a driving current for driving the organic light emitting diode. According to the OLED pixel circuit, the voltage storage module is formed between the switch module (or the driving module) and the previous scanning line Gn-1, so that the area of the voltage storage module is increased, and aperture ratio of pixel is improved without the extra addition of a signal line.

Description

technical field [0001] The invention belongs to the field of OLED display, in particular to an OLED pixel circuit used in an OLED display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, referred to as OLED), also known as organic electric laser display, has the characteristics of self-luminescence, using a very thin organic material coating and glass substrate, when the current passes, the organic material will emit light. AMOLED (ActiveMatrixOrganicLightEmittingDiode, Active Matrix Organic Light Emitting Diode panel) has the characteristics of fast response speed, high contrast ratio, and wide viewing angle compared with traditional liquid crystal panels. In addition, AMOLED also has the feature of self-illumination and does not need to use a backlight panel, so it is lighter and thinner than a traditional liquid crystal panel, and can also save the cost of a backlight module. Many advantages make it have a good application...
