OLED display structure and display device

Abstract

The embodiment of the invention discloses an OLED display structure. The OLED display structure comprises an organic light-emitting layer, a color filter layer and a light absorption layer; an array substrate, a red pixel unit, a green pixel unit and a blue pixel unit are integrated on the color filter layer, and the color filter layer is located on the organic light-emitting layer; and the light absorption layer is used for absorbing external ultraviolet light and blue light and is positioned on the color filter layer, wherein the red pixel unit, the green pixel unit and the blue pixel unit are integrated on the array substrate. By arranging the light absorption layer and (or) a blue light absorption layer in the OLED display structure, on the premise that the thickness of the pixel layer is not increased and the difficulty of the manufacturing process is improved, the absorption rate of OLED blue light is improved, and the damage of external ultraviolet light and blue light to a COA layer material is reduced, so that the problem that the color gamut is reduced due to mixed output of blue light, green light and red light is avoided, effective absorption of blue light emitted by the OLED is increased, and harm of the blue light to human eyes is reduced to a great extent.

Description

technical field [0001] The present disclosure relates to the display field, and in particular to an OLED display structure and a display device. Background technique [0002] With the continuous improvement of people's living standards, the large-area, ultra-thin and flexible market requirements for healthy and intelligent display technologies for display panels and lighting systems will gradually become an urgent need for people's lives. Global LCD (Liquid-crystal display liquid crystal display) ) Panel demand is stagnant, facing the crisis of overcapacity. The rapid occupation of the market by new display technologies has become the focus of research and development of major companies. Among them, organic light-emitting diodes or organic light-emitting diodes (organic light-emitting diodes, OLEDs) have low driving voltage, high efficiency, fast response, and wide viewing angles. , Thin and large-area, and flexible display can be realized, which has attracted extensive att...

Problems solved by technology

In addition, ultraviolet light will also have adverse effects on the internal materials of the device, reducing the life of the device

In the prior art, ultraviolet light and blue light absorbers are mostly added to one or more components of the color filter, and the absorber is usually added in the production of photoresist materials. This method will increase the thickness of the pixel layer , the preparation process is relatively complicated, which greatly increases the production cost of the display device

[0005] In the existing OLED display structure, such as figure 2 As shown, in order to improve the blue light absorption rate of pixels, the method of increasing the thickness of the pixel layer is usually used, and the thickness of the black matrix needs to be increased accordingly, and the number of quantum dot photoresists will also increase, thereby increasing the difficulty of the process and improving the manufacturing process. cost
