Organic light-emitting display cathode ring anti-reflection structure and manufacturing method, display

Abstract

The invention relates to an organic light-emitting display cathode ring anti-reflection structure, a manufacturing method thereof, and a display. The cathode ring anti-reflection structure includes a cathode ring, and a first barrier layer, a second barrier layer, and a first barrier layer sequentially fabricated on the cathode ring. Three barrier layers; the first barrier layer is in direct contact with the surface of the cathode ring, and is fabricated on the cathode ring by evaporation. In the present invention, the color filter layer is manufactured on the cathode ring at the same time in the process of manufacturing the color filter layer in the display area of ​​the organic light-emitting display, and the color filter layer is arranged on the cathode ring in a stacked manner, so that visible light cannot be transmitted. Through the film layer, the purpose of reducing or even eliminating the visible light reflection of the cathode ring is achieved, and the structure does not need to add additional processes and equipment in the production process, which can not only effectively solve the problem of cathode ring reflection, but also will not increase the production cost. The production process Simple and easy.

Description

technical field [0001] The invention relates to the technical field of OLED display, and more specifically, relates to an organic light emitting display cathode ring anti-reflection structure, a manufacturing method, and a display. Background technique [0002] The OLED display is mainly composed of a bottom drive circuit (TFT circuit) and an OLED light-emitting diode. According to the structure, it can generally be divided into two types: top emission and bottom emission. [0003] In the structure of an organic top-emitting display, the cathode ring is generally fabricated at the same time as the metal anode in the display area. However, since the anode of the organic top-emitting display is made of metal with high reflectivity, the cathode ring will reflect light when the display is normally on, which will affect the viewing experience. Therefore, it is necessary to shield or eliminate the impact of the cathode ring reflection problem in the subsequent process. In order t...

Problems solved by technology

However, since the anode of the organic top-emitting display is made of high-reflectivity metal, the cathode ring will reflect light when the display is normally lit, which will affect the viewing experience

Therefore, it is necessary to shield or eliminate the impact of the cathode ring reflection problem in the subsequent process. In order to solve this problem, the existing conventional solutions often need to increase the process and equipment occupation when shielding or eliminating, which makes the production process longer. Not only increases production cost and time cost, but also reduces production efficiency
