Abstract

The invention provides a pixel circuit comprising a luminescent control module, a light perception regulation and control module and a luminescent module. The light perception regulation and control module is connected with a regulation and control signal end, a first potential end and the luminescent control module. The light perception regulation and control module is used for receiving illumination of the luminescent module and providing the signal of the first potential end to the luminescent control module under the control of the corresponding electric signal generated according to an illumination intensity signal and the regulation and control signal end. The luminescent control module is connected with a luminescent control signal end, the light perception regulation and control module and the luminescent module. The luminescent control module is used for controlling the luminescent module to emit light under the control of the signal provided by the luminescent control signal end and the light perception regulation and control module. According to the scheme, the luminescent module can be periodically and intermittently adjusted to emit light so that reduction of the service life of a luminescent device caused by strong light emission of EL material can be alleviated.

Description

technical field

[0001] Embodiments of the present invention relate to but are not limited to the field of display technology, and in particular, refer to a pixel circuit, a driving method thereof, and a display device. Background technique

[0002] Active-Matrix Organic Light Emitting Diode (AMOLED) is one of the hotspots in the field of flat panel display research today. Compared with liquid crystal displays, OLED (Organic Light-Emitting Diode, organic light-emitting diode) has low energy consumption, With the advantages of low production cost, self-illumination, wide viewing angle and fast response speed, OLED has begun to replace the traditional LCD (Liquid Crystal Display, Liquid Crystal Display) in display fields such as mobile phones, PDAs (Personal Digital Assistants), and digital cameras. monitor) display.

[0003] In conventional OLED display devices, RGB (red, green and blue) evaporated materials are different, and the luminous characteristics of different materia...
