Abstract

The invention provides an aging compensation system and method for an OLED component. The aging compensation system for the OLED component comprises a pixel circuit, a first power source, a second power source, an aging detection circuit and a driving chip. The pixel circuit comprises the OLED component connected between the first power source and the second power source, the driving chip is connected with the pixel circuit through a data line and used for driving the OLED component to emit light, and the aging detection circuit is connected between the anode of the OLED component and the driving chip which measures the anode voltage of the OLED component through the aging detection circuit. According to the aging compensation system and method for the OLED component, the aging detection circuit is additionally arranged on a traditional pixel circuit so that the driving chip can monitor the aging conditions of the OLED component in real time through aging testing points, and segmented compensation can be performed according to difference of the aging conditions.

Description

Technical field [0001] The present invention relates to the technical field of flat panel displays, in particular to an OLED device aging compensation system and an aging compensation method thereof. Background technique [0002] The organic light-emitting display uses organic light-emitting diodes (Organic Lighting Emitting Diode, OLED for short) to display images. It is an active light-emitting display. Its display method is similar to that of the traditional thin film transistor liquid crystal display (Thin Film Transistor liquid crystal display for short). TFT-LCD) has different display modes, no backlight, and has many advantages such as high contrast, fast response speed, lightness and thinness. Therefore, organic light emitting displays are known as a new generation of displays that can replace thin film transistor liquid crystal displays. [0003] Generally, each pixel of an organic light emitting display includes an OLED device and a pixel driving circuit for driving the ...
