Micromirror array, OLED display screen and manufacturing method thereof

Abstract

The invention discloses a micromirror array, an OLED display screen and a manufacturing method thereof. The micromirror array comprises a substrate chip which is internally provided with a plurality of pixel electrodes, wherein the plurality of pixel electrodes are arranged in a matrix; a plurality of first curved surface grooves which are formed on the substrate chip, wherein the first curved surface grooves are in one-to-one correspondence with the pixel electrodes, and the pixel electrodes are exposed out of the first curved surface grooves; first conductive layers which are arranged on the surfaces of the first curved grooves and are electrically connected with the pixel electrodes; light-emitting layers which are arranged on the first conductive layers, wherein the light-emitting layers on the adjacent first conductive layers are connected with each other; and second conductive layers disposed on the light emitting layers. According to the micromirror array, the intensity of the light emitted by the light-emitting layer can be enhanced, so that the brightness of the display screen can be remarkably improved, and the utilization rate of the light emitted by the light-emitting layer is increased.

Description

technical field [0001] The present application relates to the technical field of display screens, in particular to a micromirror array, an OLED display screen and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) displays are bendable, thin, and have wide viewing angles, bright colors, etc., and have been widely used in Augmented Reality (AR) and Virtual Reality (VR). AR and VR are immersive experiences that require the display to match the human visual system as much as possible, and require the display to have high brightness, high contrast, and high color gamut. [0003] At present, the mainstream method for the mass production of silicon-based OLED panels is to vacuum-deposit white light organic materials as the main light-emitting layer, and then realize full-color display through RGB color gel graphics, and the optical transmittance of RGB color gel is only about 30%. The utilization rate of light emitted by the material...
