Problems solved by technology

However, compared with the blue light pixel, the excessively shared voltage and corresponding power consumption of the driving transistors in the active driving circuit of the red and green pixels do not contribute to the light emission of the light-emitting device, but become heat dissipation, which not only reduces the display device Electro-optical efficiency, and because the heat in the circuit reaches a certain level, it will affect the performance of electronic components, thus affecting the display effect of the display device

Abstract

An embodiment of the invention provides a pixel structure, a pixel unit structure, a display panel and a display device and aims at improving electro-optical efficiency of the display device. The pixel structure comprises a pixel active driving circuit and at least two luminescent devices connected with each other in series and connected with the pixel active driving circuit. The luminescent devices form a luminescent device group, and the pixel active driving circuit drives the luminescent devices to emit light.

Description

technical field [0001] The present invention relates to the field of organic light emitting technology, in particular to a pixel structure, a pixel unit structure, a display panel and a display device. Background technique [0002] Organic light-emitting displays are called the next generation of fantasy because of their advantages such as full solid state, active light emission, high contrast, ultra-thin, low power consumption, wide viewing angle, fast response, wide working range, and easy realization of flexible display and 3D display. monitor. At the same time, since the light-emitting device has the feature of being able to form a large-area film, it can become an ideal large-size flat panel display device. Currently, the widely used light emitting device is an organic light emitting diode (Organic Light Emitting Diode, OLED). Large-sized organic light-emitting display devices made of OLEDs, such as OLED color TV sets and OLED tablet computers, have become the goals p...
