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 present invention provides a method for manufacturing an organic light-emitting display panel, which is used to improve the electro-optical efficiency of a display device. The method includes: forming a first anode and a second anode on a substrate, sequentially forming a first hole transport layer, a first organic light-emitting layer, a first electron transport layer, a An insulating layer and a first cathode in a certain width area on the side of the organic light-emitting layer; a second hole transport layer, a second organic light-emitting layer, and a second electron transport layer are sequentially formed on the second anode, and are located on the periphery of the second anode The insulating layer, the second cathode; the second cathode is partly connected to the first anode.

Description

[0001] The present invention application is a divisional application of an invention application with a filing date of December 13, 2012, an application number of 201210539995.X, and an invention title of "a pixel structure, a pixel unit structure, a display panel, and a display device". technical field [0002] The present invention relates to the field of organic light emitting technology, in particular to a method for manufacturing an organic light emitting display panel. Background technique [0003] 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 displ...
