Problems solved by technology

[0004] The current OLED display panel will enlarge the sub-pixel layer of the light-emitting layer to ensure the light-emitting life of the sub-pixel layer, but this will sacrifice the pixel density of the display panel, resulting in poor clarity of the display panel

Abstract

The embodiment of the invention relates to the technical field of display, and discloses a display panel. The first electrode layer is arranged on the substrate; the light-emitting layer is located on the first electrode layer, and the light-emitting layer comprises a first sub-pixel; the first functional layer is located between the first electrode layer and the light-emitting layer; wherein the first functional layer is provided with a first groove, and the first sub-pixel is arranged in the first groove; the first light guide layer is located on the side, away from the first electrode layer, of the first sub-pixel and covers the first sub-pixel, the side, away from the first electrode layer, of the first light guide layer comprises a first effective light emitting area and a first invalid light emitting area, and the area of the first effective light emitting area is smaller than the light emitting area of the first sub-pixel. According to the display panel, the light emitting service life and the pixel density of the display panel can be guaranteed at the same time.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular to a display panel. Background technique [0002] With the rapid development of electronic display technology, organic light-emitting diode (Organic Light-Emitting Diode, OLED) as a self-luminous device, because of its low power consumption, high color saturation, wide viewing angle, thin thickness, flexible It is widely used in display panels such as terminal equipment and wearable equipment due to its excellent performance such as simplification and no need for a backlight source. [0003] The RGB three-primary-color method is more commonly used in the current OLED display panel light colorization method, that is, in the preparation process of the OLED display panel, the red sub-pixel layer, the blue sub-pixel layer and the green sub-pixel layer are arranged in the light-emitting layer, and the three sub-pixel layers It emits light of three colors of ...
