Abstract

An organic light-emitting diode (OLED) display device includes an active array substrate, at least one OLED, and an encapsulating plate. The active array substrate includes a light absorption layer and at least one active element. The active element is disposed on the light absorption layer. The OLED is disposed on the active array substrate. The OLED includes a first electrode, a second electrodeand an organic light-emitting layer. The first electrode is disposed adjacent to the active element, and the second electrode is opposite to the first electrode. Both the first and second electrodeshave a high transmittance greater than 0.6 and a low reflection in a wavelength range of visible light. The organic light-emitting layer is interposed between the first and the second electrodes. Theencapsulating plate is disposed over the OLED. The first and second electrodes are made of a material of low reflection rage and high transmittance, and the light absorption layer is used to reduce and eliminate an original optical reflection phenomenon, and the daylight 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 displays are regarded as the mainstream technology of the next generation. 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 downward can be reflected upward by the driving electrodes below, thereby obtaining higher light extraction efficiency. . In addition, some people have proposed organic light-emitting diode displays with micro-optical resonant cavities. In this technology, in addition to the high-reflectivity materials that must be used for the lower driving electrodes of organic light-emitting diodes, the upper driving electrodes must also have certain reflectivity. This type of display can provide better color saturation and higher bri...
