Problems solved by technology

However, at the same time, the internal light LI generated by the light-emitting layer 12 of the organic light-emitting diode light-emitting structure 10 will also pass through the optical anti-reflection structure 20 after being emitted, because the transmittance of the optical anti-reflection structure 20 is about 40%, so The luminous efficiency of the display device will be greatly reduced
In addition, an additional optical anti-reflection structure 20 will also increase the thickness and weight of the overall device

Abstract

An organic light-emitting diode display device includes a substrate, a bottom electrode, a first organic layer, a light-emitting layer, a second organic layer, a top electrode and an optical stop layer. The bottom electrode is disposed on the substrate. The first organic layer is disposed on the bottom electrode. The light-emitting layer is disposed on the first organic layer. The second organic layer is disposed on the light-emitting layer. The top electrode which is transparent or semitransparent is disposed on the second organic layer. The optical stop layer is disposed on a side of the light-emitting layer opposite to the second organic layer. The top electrode is transparent or semitransparent, a function layer absorbing light is arranged in the structure to absorb external light generated in the external environment, influence of reflection of the external light on the image quality is avoided, and brightness contrast of the organic light-emitting diode display device is more obvious. Thus, no externally hung structure is needed, the self light emitting efficiency is not influenced, the thickness and weight of a product are both reduced, and the design and production cost isreduced.

Description

technical field [0001] The invention relates to an organic light emitting diode display device. Background technique [0002] Organic Light Emitting Diode (OLED) is a light-emitting element using a luminous organic compound. It has self-luminous characteristics, and its thinner, display quality, and power-saving characteristics are superior to Liquid Crystal Display (LCD) . Due to the wide viewing angle, high response speed, ultra-thin and other characteristics of the organic light emitting diode, the application range of the organic light emitting diode panel is becoming wider and wider. [0003] Because the organic light-emitting diode display device is self-illuminating, it will have display characteristics of high contrast and high color saturation indoors or under low ambient light conditions. However, if the user is under a high-intensity ambient light source, because the brightness of the OLED itself will be lower than the ambient light, and the upper and lower elec...
