Abstract
The invention discloses an organic light-emitting display device, a preparation method and a display device. The organic light emitting display device includes: a substrate; a first electrode, the first electrode is disposed on the substrate; a light emitting layer, the light emitting layer is disposed on a side of the first electrode away from the substrate; A second electrode, the second electrode is arranged on the side of the light-emitting layer away from the first electrode; and a polarized reflective layer, the polarized reflective layer is arranged on the side of the first electrode away from the light-emitting layer , or the side of the second electrode away from the light-emitting layer. Thus, the electrode reflectivity of the organic light-emitting display device can be improved, the brightness and stability of the device can be improved, the polarization characteristics of the output light of the device can be improved, and the luminous quality of the device can be improved.
Description
technical field [0001] The present invention relates to the field of organic optoelectronics, in particular to an organic light-emitting display device, a preparation method, and a display device. Background technique [0002] Organic light-emitting display (OLED) is a thin-film light-emitting device made of organic semiconductor materials and driven by DC voltage. The organic light-emitting display technology is different from the traditional LCD display method. It does not require a backlight and uses a very thin organic material coating. and glass substrates, these organic materials emit light when an electric current is passed through them. Moreover, the organic light-emitting display screen can be made lighter and thinner, and has the advantages of large viewing angle, wide color gamut, high brightness, power saving, and flexible display. According to the direction in which light is emitted, organic light emitting display devices can be classified into top emission org...
