Abstract
The invention provides a top light-emitting display panel and a display device.The top light-emitting display panel comprises a substrate, light-emitting structures and a cover plate layer, wherein the light-emitting structures comprise the first light-emitting structure, the second light-emitting structure and the third light-emitting structure, and the corresponding light-emitting wavelengths are the first wavelength, the second wavelength and the third wavelength; the cover plate layer is located on the side, away from the substrate, of the light-emitting structures and at least comprises two of a first area located on the first light-emitting structure, a second area located on the second light-emitting structure and a third area located on the third light-emitting structure, and two times of the equivalent optical path of the first area in the thickness direction is the integral multiple of the first wavelength. Twice of the equivalent optical path of the second area in the thickness direction is the integral multiple of the second wavelength, and twice of the equivalent optical path of the third area in the thickness direction is the integral multiple of the third wavelength. According to the embodiment of the invention, the light emitting rates corresponding to the first wavelength, the second wavelength and the third wavelength can be simultaneously improved, the power consumption is reduced, and the service life of the display panel is prolonged.
Description
technical field [0001] The present invention relates to the technical field of display equipment, in particular to a top-emitting display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED), as a new type of light-emitting device, has shown great application potential in the fields of display and lighting, so it has received strong attention from academia and industry. In the field of display, compared with LCD, OLED has the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright color, light and thin, etc., and is considered to be the next generation display technology. [0003] Existing OLED devices are usually composed of an anode layer, a light-emitting layer and a cathode layer. According to the different light-emitting surfaces, they can be divided into two types: bottom emission and top emission. Because top emission devices can obtain a larger aperture ratio, they have become a research hot...
