Abstract

The present invention provides a display substrate and a display device. The display substrate includes a plurality of pixel units. Each of the pixel units includes a reflective anode layer, a semi-transmissive cathode layer, and an organic light-emitting layer between the anode layer and the cathode layer, wherein a microcavity structure is formed between the cathode layer and the anode layer. The microcavity structures corresponding to the pixel units of different colors have different lengths. In this way, the brightness of the light of different colors can be enhanced by the microcavity structures in the pixel units having the corresponding colors in the display substrate, and the microcavity effect in the display substrate can realize resonance enhancement of different monochromatic lights, thereby improving the light-emitting efficiency and the color gamut of the display device..

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate and a display device. Background technique [0002] When existing display devices, especially microdisplays, are used in near-eye display fields such as augmented reality, their brightness cannot meet the requirements of outdoor application scenarios. The strong microcavity effect in white light devices can effectively increase the brightness of part of the light. But correspondingly, the microcavity effect will also weaken the intensity of light in other wavelength bands, resulting in poor luminous efficiency of the microdisplay. [0003] It can be seen that there is an urgent need for an improved microcavity structure to achieve enhanced luminescence of a display device. Contents of the invention [0004] Embodiments of the present invention provide a display substrate and a display device, so as to improve the microcavity structure and achieve ...
