Abstract

The embodiment of the invention provides a display panel and a display device, relates to the technical field of display, and can improve the light extraction efficiency of the display panel. The display panel adopts a silicon substrate and the display panel includes a plurality of light emitting units, and each of the light emitting units includes a light emitting layer; the plurality of light emitting units include a plurality of first light emitting units and a plurality of second light emitting units, wherein various light emitting layers in the first light emitting units are not adjacentto each other; and the second light emitting units comprise at least two layers of specific light emitting layers which are adjacent to each other and share a carrier transmission layer.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic light emitting diode (Organic Light Emitting Diode, referred to as OLED) display, with its unique advantages, such as fast response, self-illumination, etc., has attracted the attention of the market; and in recent years, the application of OLED display is also very diversified, such as , in the fields of flexibility, transparency, micro-display and other applications. [0003] Schematically, take the application of OLED displays in the field of microdisplays as an example. For example, in AR (Augmented Reality, Augmented Reality) display, due to the loss of light by optical waveguides and gratings (low light extraction efficiency), and imaging amplification and color The requirements of the field put forward higher brightness requirements for micro-display devices, which makes the existing conv...
