Abstract

The invention discloses a pixel structure and its driving method, a display panel and a display device, which include at least two identical pixel circuits: a first pixel circuit and a second pixel circuit, and a pixel circuit for connecting the first pixel circuit and the second pixel circuit. The first conduction control module, the second conduction control module and the third conduction control module of the pixel circuit; when the pixel structure is used for display, the first conduction control module and the second conduction control module are in the first control Under the control of the terminal, the first pixel circuit and the second pixel circuit are connected in parallel, and the light emission between the pixel circuits is not affected; when the pixel structure is used for photoelectric conversion to form a solar cell, the third conduction control module can At least two pixel circuits are connected in series under control, and then the photovoltaic voltages of each light-emitting device are superimposed to reach the voltage for charging the battery, so that the pixel structure can realize the composite function of pixel display and photoelectric conversion to form a solar cell.

Description

technical field [0001] The present invention relates to the technical field of electroluminescence, and in particular, to a pixel structure and a driving method thereof, a display panel and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) is one of the hot spots in the field of flat panel display research. Compared with liquid crystal display, OLED has the advantages of low energy consumption, low production cost, self-illumination, wide viewing angle and fast response speed. , In the field of flat panel displays such as mobile phones, PDAs, and digital cameras, OLED has begun to replace the traditional liquid crystal display (Liquid Crystal Display, LCD). Among them, pixel circuit design is the core technical content of OLED display, which has important research significance. [0003] And OLED is a structure based on organic semiconductor heterojunction, which reflects light-emitting characteristics under positive bias and photoelectric c...
