Abstract

The invention discloses a diffraction suppression optical element and a manufacturing method thereof. The diffraction suppression optical element comprises a transparent substrate and a plurality of shading areas formed on the transparent substrate. The method comprises the following steps: providing an imprint template; imprinting a transparent material coated on a transparent substrate by using an imprinting template so as to form a plurality of grooves in the transparent material; and applying a light-absorbing material on the imprinted transparent material, so that the plurality of grooves are filled with the light-absorbing material and the rest parts of the transparent material are exposed. According to the embodiment of the invention, products can be continuously produced by using a micro-nano imprint copy process only by using one imprint template, so that batch and rapid production can be realized, and the productivity is easy to improve; and moreover, the use of ultra-high-flatness glass and expensive equipment required by a semiconductor process can be avoided, and the cost can be greatly reduced.

Description

technical field [0001] The present invention generally relates to display screen technology, and in particular to a diffraction-suppressing optical element for eliminating the diffraction effect of a transparent display screen and a method of manufacturing the same. Background technique [0002] With the development of transparent display technology, the popularity of under-screen projection and under-screen camera technology is getting higher and higher. The camera / projector is placed under the transparent display, and the appearance of the display is complete, achieving a true full-screen effect. However, due to the periodic arrangement of pixels on the display screen, light rays are diffracted when passing through the transparent display screen, which affects the quality of imaging or projection. In order to ensure the quality of off-screen projection and off-screen imaging, it is necessary to add structural units that suppress diffraction. [0003] One solution to supp...
