Abstract

An active organic light emitting diode circuit and its operation method in the disclosure. Active organic light emitting diode circuit including organic light emitting diode, switching circuit, compensation circuit, drive circuit and reset circuit. Compensation circuit switch circuit is connected, and includes the first capacitor. Driving circuit to drive by compensation circuit, in order to provide an organic light emitting diode drive current. Reset circuit connected to the ends of the first capacitor, and connecting line. Reset circuit is used to according to the potential change in the first line of the potential at each end of the capacitor, in at one end of the first capacitor and the reference channel formed between the power, and the release of the first capacitor's charge.

Description

【Technical field】 [0001] The disclosure relates to a diode circuit and its operating method, and more particularly to an active organic light emitting diode circuit and its operating method. 【Background technique】 [0002] Due to the development of display technology in recent years, flat panel displays have been widely used in daily life. Among them, the Active Matrix OLED (AMOLED) display is very popular because of its high image quality, high contrast and high response speed. [0003] figure 1 is a schematic diagram of an active organic light emitting diode display 10 in the prior art. The active OLED display 10 includes a data driver 20 , a scan driver 30 and a display area 40 . The data driver 20 controls the data lines DL_1, DL_2, . . . , etc., and the scan driver 30 controls the scan lines SL_1, SL_2, . The data lines DL_1 , DL_2 , . . . and the scan lines SL_1 , SL_2 , . Each display unit 50 includes an active organic light emitting diode circuit, and the active...
