Problems solved by technology

Although the anti-reflection optical film group with this structure solves the problem of reflection of external light, it leads to a loss of 60% of the brightness of the OLED panel, because the transmittance of a polarizer is only about 40-50%.
Therefore, the known

Abstract

An OLED display device includes a substrate, an active element array, at least one OLED, a light absorption layer or an optical scattering layer, and an encapsulation plate. The substrate includes anupper surface and a lower surface opposite to the upper surface. The active element array is configured in the side of the upper surface of the substrate. The OLED are disposed over the active array substrate. The OLED includes a first electrode, a second electrode, and an organic light-emitting layer. The first electrode is disposed in a side adjacent to the active element array, and the second electrode is opposite to the first electrode. Both the first and second electrodes have a high transmittance and a low reflection in a wavelength range of visible light. The organic light-emitting layer is interposed between the first and second electrodes. The light absorption layer or optical scattering layer is disposed between the OLED and the substrate. The encapsulation plate is disposed overthe second electrode. Thus, the OLED display device can solve the problem of reflection of ambient light to creation extent, and the light emitting efficiency of the OLED display device can be improved.

Description

technical field [0001] The invention relates to an organic light emitting diode display device. Background technique [0002] Organic light-emitting diode display panels are regarded as the mainstream technology of the next generation. In a general organic light emitting diode display panel, when the user uses the organic light emitting diode display under a high-brightness ambient light source, the light reflected by the panel from the outside will seriously affect the display screen of the original display, causing the user to be unable to see the original display clearly. display screen. [0003] In traditional organic light emitting diode displays, in order to improve light extraction efficiency, materials with high reflectivity are used as the driving electrodes of organic light emitting diodes, so that the light emitted to the bottom can be reflected by the driving electrodes below, thereby obtaining higher light extraction efficiency . In addition, some people have...
