Problems solved by technology

However, the light emitted by the organic light-emitting elements at the top and second top of the stack structure needs to penetrate through multi-layer electrodes and multiple groups of organic material layers, the luminous efficiency will be attenuated, and the light color will be caused by the micro-cavity effect. ) resulting in an offset phenomenon
[0005] In addition, traditionally, the bottom surface of organic electroluminescent display elements is a metal film layer, so in practical applications, the contrast of organic electroluminescent display panels will be greatly reduced due to the reflection of external ambient light, resulting in poor image recognition

Abstract

An all colored organic electro luminescence display element consists of shared electrode, the first sub pixel organic material layer and the first corresponding electrode, the second sub pixel organic material layer and the second corresponding electrode, the third sub pixel organic material layer and the third corresponding electrode. It is prepared as setting the first sub pixel organic material layer SOML between shared electrode and the first corresponding electrode CE, setting the second and the third SOML in parallel at another side surface of shared electrode and setting the second SOML between shared electrode and the second CE, setting the third SOML between shared electrode and the third CE.

Description

technical field [0001] The invention relates to an organic electroluminescent display element and its panel, in particular to a full-color organic electroluminescent display element and its panel. Background technique [0002] Organic electroluminescence (OEL) display, which has many characteristics such as thinness, high resolution, power saving of liquid crystal display, active light emission and high response speed of inorganic light-emitting diode, is considered to be the next generation of flat-panel display. Emerging application technologies. [0003] Full-color organic light-emitting displays can be mainly divided into two categories: light-color conversion and RGB side-by-side light-emitting structures. The light color conversion type includes a color filter structure and a color conversion layer structure. The color filter structure uses white organic light-emitting diodes, combined with color filters to achieve full-color effects. Its advantage is that it can be d...
