Abstract
The invention discloses a display panel and a display device. The display panel further comprises a substrate, a light-emitting layer, a low-refractive-index layer and a high-refractive-index layer. The light-emitting layer is arranged on the substrate, and the light-emitting layer comprises a plurality of light-emitting parts arranged in the display area; the low-refractive-index layer is arranged on the light-emitting layer and comprises a plurality of openings which are distributed in the display area in an array mode and correspond to the light-emitting parts and first grooves distributed in the non-display area; the high-refractive-index layer is arranged on the low-refractive-index layer and fills the multiple openings, and the side, away from the low-refractive-index layer, of the high-refractive-index layer is provided with protrusions located in the display area; wherein the openings comprise a first opening closest to the first groove, the distance from the first groove to the top end of the protrusion in the first direction is larger than the distance from the first groove to the first opening in the first direction, and the first direction is the direction from the non-display area to the display area. According to the invention, the coverage area of the high-refractive-index layer can be effectively limited, and the space of the non-display area is saved, so that narrow-frame display is realized.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Compared with traditional liquid crystal displays (LCDs), organic light-emitting diode (OLED) display panels have the advantages of light weight, wide viewing angle, fast response time, low temperature resistance, and high luminous efficiency. The display industry has always been regarded as the next-generation new display technology, especially the OLED display panel can be made into a flexible display that can be bent on a flexible substrate, which is a huge advantage of the OLED display panel. [0003] At present, in order to reduce the power consumption of the OLED display panel and improve the efficiency of the OLED display panel, panel manufacturers continue to introduce new technologies. With the help of geometric optics, by arranging a Microlens Pattern (MLP) in the OLED screen, the relativ...
