Abstract

The invention provides a display substrate, a preparation method thereof and a display module. The display substrate comprises a first substrate and a light modulation layer, and the first substrate comprises a plurality of sub-pixels arranged in an array; the light modulation layer is located on one side of the first substrate, the light modulation layer comprises a plurality of optical units arranged in an array, and orthographic projections of the optical units on the first substrate and orthographic projections of the sub-pixels on the first substrate are at least partially overlapped; each optical unit comprises periodically arranged microstructures, the microstructures are used for enabling the ambient light emitted to the microstructures to be diffracted, and emergent light formed after diffraction is emitted out in a first preset included angle range with the normal direction of the plane where the first substrate is located as the center, so that the utilization rate of the ambient light reflected out through the light modulation layer is increased, and the contrast ratio and the visual angle of the whole display substrate are increased.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a display substrate, a manufacturing method thereof, and a display module. Background technique [0002] Conventional liquid crystal displays (LCDs) are transmissive, and can directly test the brightness to measure the brightness and darkness of the display. The reflective liquid crystal display (RLCD) displays the ambient light through the light modulation layer, does not need to install a backlight module, and uses reflectivity to measure the quality of the display. [0003] However, due to the limitation of the optical path principle of the reflective liquid crystal display, the utilization rate of ambient light reflected by the light modulation layer is low, thereby affecting the contrast and viewing angle of the entire display. Contents of the invention [0004] In view of the shortcomings of the existing methods, the presen...
