Display system and applicable head-mounted display thereof

Abstract

The invention relates to a display system, and the system comprises an optical integral column, a solid state light-emitting element, a first total internal reflection prism, a reflector, a second total internal reflection prism, a digital micromirror device, and an ocular lens. The solid state light-emitting element is disposed at an inlet end of the optical integral column. The first total internal reflection prism is provided with a first surface, a second surface and a third surface, wherein the first surface is adjacent to the outlet end of the optical integral column. The reflector is disposed on the second surface. The second total internal reflection prism is provided with a fourth surface, a fifth surface and a sixth surface, wherein the fourth surface contacts with the third surface. The digital micromirror device is disposed to be adjacent to the fifth surface. The ocular lens is adjacent to the sixth surface. Light enters the digital micromirror device along an illuminating optical path, and then is projected to an imaging surface along an imaging optical path. Therefore, the size of the display system can be effectively reduced.

Description

technical field [0001] The present invention relates to a display system, in particular to a display system and a head-mounted display applicable thereto. Background technique [0002] In recent years, head-mounted displays and near-eye displays have become a research and development direction of technological products, which are expected to bring more convenient life to users, and are even further applied to the Internet of Things. [0003] Generally speaking, the current head-mounted displays are mostly presented in the shape of glasses. see figure 1 , which shows a schematic diagram of the structure of a conventional head-mounted display. Such as figure 1 As shown, the current traditional head-mounted display 1 usually has an optical device 11 arranged on the spectacle frame 12, and through the design of the optical path, the image or light can be projected into the user's eyes E, so that the user can see the image. However, due to the limitation of the thickness of t...
