Problems solved by technology

[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 In order to meet the needs of the field, higher brightness requirements are put forward for micro-display devices, which leads to the inability of existing conventional displays to meet the requirements.

Abstract

Embodiments of the present invention provide a display panel and a display device, which relate to the field of display technology and can improve the light extraction efficiency of the display panel; the display panel uses a silicon substrate, and the display panel includes a plurality of light-emitting units, and each light-emitting unit includes a light-emitting layer The plurality of light-emitting units includes a plurality of first light-emitting units and a plurality of second light-emitting units; wherein, the light-emitting layers in the first light-emitting units are not adjacent, and the second light-emitting units include at least two layers that are adjacent and share the current carrying Specific emissive layer of the sub-transport 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...
