Abstract

The present invention provides one kind of light emitting circuit and method with power saving function. The light emitting circuit has one reactive element connected electrically to the power supply and drive circuit to regulate the overall power consumption automatically based on the total current the pixel units consume. Therefore, the present invention can reduce power consumption and fluctuation without affecting display quality.

Description

Technical field [0001] The present invention relates to a self-luminous circuit and method with power-saving function, in particular to an organic light-emitting diode circuit with power-saving function. Background technique [0002] Since emissive displays have the advantages of thinness, high color saturation, active luminescence, fast display speed, and power saving, they are regarded as one of the flat display technologies to replace liquid crystal displays in the next generation. Organic Electro-luminescence Display (OELD) is one of the main technologies of self-luminous display, also known as Organic Light Emitting Diode (OLED) display panel, which combines liquid crystal display The advantages of both (LCD) and diode (LED). [0003] figure 1 A schematic circuit diagram showing a pixel unit of an organic light emitting diode display. In each pixel unit 100, after the data input signal Vdata is input to the gate G of the P-type thin film transistor 101, the formed gate-sou...
