Organic light-emitting display panel

Abstract

The organic luminous display faceplate comprises a base plate including defined multiple first pixel areas, second pixel areas and third pixel areas, as well as multiple programmable first organic light emitting diodes (OLED), second OLED and third OLED set up at first pixel area, second pixel area and third pixel area respectively. First OLED possesses first common electrode connected to first conducting wire electrically. Second OLED possesses second common electrode connected to second conducting wire electrically. The first conducting wire and the second conducting wire are connected to external power source. Radiation colors of first and second OLED are determined based on different temperatures.

Description

technical field [0001] The present invention relates to an organic light emitting display panel (organic light emitting display panel, OLED panel), in particular to an organic light emitting display panel using a common electrode (common electrode) of an organic light emitting diode to form a heating circuit structure. Background technique [0002] With the rapid development of science and technology, thin, light, power-saving, and portable intelligent information products have filled our living space, and monitors have played a very important role in it, whether it is mobile phones, personal digital assistants or notebook computers , both require a display as an interface for man-machine communication. In recent years, the display has made great progress under the demand of high image quality, large screen and low cost. Among them, with the successful development of organic materials, the organic light-emitting display has a simple structure and excellent operating temperat...

Problems solved by technology

[0007] Although in theory the light emission color of each organic light emitting diode can be controlled by changing the material of the organic light emitting layer 28, and by forming pixels of different colors, the organic light emitting layer 28 is in fact a multi-layer stacked structure, and its structure is quite complicated. Therefore, if it is desired to use organic light-emitting layers 28 of different materials to form pixels of different colors, it is difficult to manufacture. Therefore, in the prior art, organic light-emitting diodes that can emit white light are mostly formed first, and then by matching appropriate red , blue, and green three-color filters to generate red, blue, and green pixels to form a color pixel

However, this method needs to set up optical filters, and it is necessary to control the alignment accuracy in the process to avoid unevenness of the three colors of light, so it often causes additional restrictions in the layout configuration (layout), thereby reducing the Aperture ratio
