Problems solved by technology

[0003] However, the lifespan of luminescent materials often limits the application range of OLEDs, especially for blue light materials, whose lifespan is much lower than that of red and green light materials. Therefore, how to effectively improve the lifespan of OLEDs and improve the quality of display images has become the goal of pursuit.

Abstract

The present invention relates to a drive method of a display device, comprising receiving an input signal which includes input red gray-scale values, input green gray-scale values and input blue gray-scale values; and adjusting the input signal to an output signal which includes output red gray-scale values, output green gray-scale values and output blue gray-scale values. The output red gray-scale values is not greater than the input red gray-scale values, the output green gray-scale values is not less than the input green gray-scale values, and the output blue gray-scale values is not greater than the input blue gray-scale values.

Description

technical field [0001] The invention relates to a driving method of a display, in particular to a driving method of an organic light emitting diode display. Background technique [0002] The basic structure of an organic light-emitting device (OLED) is a thin, transparent indium tin oxide (ITO) with semiconducting properties, which is connected to the anode of the power, plus another metal cathode, wrapped into a package like Sandwich structure. The whole structural layer includes: hole transport layer (HTL), light emitting layer (EL) and electron transport layer (ETL). When the power is supplied to an appropriate voltage, the anode holes and cathode charges will combine in the light-emitting layer to produce light, and the three primary colors of red, green and blue are produced according to their formulas to form the basic colors. The characteristic of OLED is that it emits light by itself, so it has high visibility and brightness, plus fast response, light weight, thin ...
