Problems solved by technology

In addition, the above settings have affected the optimal structure of the organic film layer, thus affecting the stability and efficiency of the light emitting device
On the other hand, in order not to affect the optimization of the organic film layer, a combination of a polarizer and a retardation film is currently used. However, the combination of these two optical film layers has relatively high cost, and increases the complexity of the process

Embodiment Construction

[0029] Please refer to FIG. 2 . FIG. 2 is a schematic diagram of a high-contrast organic light-emitting display according to a first preferred embodiment of the present invention. According to the first preferred embodiment of the present invention, the high-contrast organic light-emitting display 200 includes a transparent substrate 210, such as a glass substrate, a quartz substrate or a polyacrylate (polyacrylates) substrate, a polymethacrylate (polymethacrylates) substrate, etc. to carry the light emitting structure 220 . The light emitting structure 220 includes a transparent lower electrode 222 , an organic layer 224 and an upper electrode structure 226 . Wherein, the material of the transparent bottom electrode 222 can be selected from materials such as Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO), etc., as the anode electrode for inputting holes. In this embodiment, the organic layer 224 is the light-emitting layer, which can be made of polyphenylenevinylenes, polyf...

Abstract

The display unit includes transparent base plate, radiation structure, cover glass plate, and light absorption layer. Being setup on surface of the cover glass plate, the light absorption layer is in use for absorbing external light in order to reduce its reflection. The display also includes sealing material setup between the transparent base plate and the cover glass plate. Based on thickness of radiation structure and thickness of light absorption layer, the sealing material adjusts space between the transparent base plate and the cover glass plate.

Description

technical field [0001] The present invention relates to a high-contrast organic light-emitting display, in particular to an organic light-emitting display in which a light-absorbing layer is arranged on the surface of a cover glass to reduce the reflection of an external light source. Background technique [0002] Organic Light Emitting Display (OLED) has high brightness, wide viewing angle, self-illumination, flexibility, full color, high response speed, low operating voltage, simple structure of thin film elements, and operating environment temperature range It is large and can be fabricated on any substrate or even a plastic substrate. Although it started late, it has attracted attention in the flat-panel display market, especially in the field of medium and small-sized portable displays. [0003] Referring to FIG. 1, a bottom emission organic light emitting display 100 includes a transparent substrate 110 on which a hole-injecting layer (HIL) 120, an organic hole-transpo...
