Problems solved by technology

However, if the overall weight, thickness, and even future flexible applications are considered, it is inevitable to use plastic substrates, but the use of plastic substrates will reduce the ability to block moisture and oxygen penetration, thereby reducing Lifespan and Quality of Organic Light Emitting Diodes

Abstract

An organic light-emitting diode display device includes a bottom substrate, an insulating layer, a bottom electrode, an organic layer, a top electrode, a top substrate, and an optical blocking layer.The insulating layer is disposed on the bottom substrate. The bottom electrode is disposed on the insulating layer, and the bottom electrode is made of a transparent conductive material or a semitransparent conductive material. The organic layer is disposed on the bottom electrode. The top electrode is disposed on the organic layer, and the top electrode is made of a transparent conductive material or a semitransparent conductive material. The top substrate is disposed on the top electrode, and the top substrate corresponds to the bottom electrode to function as a package structure. The optical blocking layer is disposed on a side of the top electrode away from the organic layer. The lower and upper electrodes are both transparent or semi-transparent, external light penetrates the lower and upper electrodes and is then absorbed by the optical blocking layer, and thus, the OLED display device can avoid reflection of the external light and further influence on the image quality, and thedarkness contrast of the OLED display device is more obvious.

Description

technical field [0001] The invention relates to an organic light emitting diode display device. Background technique [0002] Organic Light Emitting Diode (OLED) display devices are light-emitting elements using luminescent organic compounds, which have self-luminous properties, and are superior to Liquid Crystal Displays (Liquid Crystal Display, LCD). Due to the wide viewing angle, high response speed, and ultra-thin characteristics of the OLED display device, the application range of the OLED display device is becoming wider and wider. [0003] Organic light emitting diode display devices are considered to be the mainstream technology of the next generation. In a traditional organic light emitting diode display device, in order to improve light extraction efficiency, a material with high reflectivity is used as the lower driving electrode of the organic light emitting diode, so that the light emitted downward can be reflected by the lower driving electrode and go upward,...
