Display device, projection device, near-eye display device and method for forming same

Abstract

The invention discloses a display device, a projection device and a near sight display device and a forming method thereof. The display device comprises a substrate, a semiconductor switch array, a plane light guide panel and a transmission light valve array, wherein the semiconductor switch array is positioned on the substrate; the plane light guide panel is positioned on the semiconductor switch array and comprises a transparent medium layer, and a light path deflection micro device and an electrical connector which are positioned in the transparent medium layer; the electrical connector iselectrically connected with the semiconductor switch array; the transmission light valve array is positioned on the plane light guide panel and is provided with a plurality of transmission light valves which are arranged to form an array; the electrical connector is also electrically connected with the transmission light valve array; the semiconductor switch array controls the opening and the closing of the transmission light valves by the electrical connector; light which is transmitted from the side of the plane light guide panel to the plane light guide panel is deflected by the light pathdeflection micro device, transmitted to the transmission light valve array and transmitted to the outside after passing through the transmission light valve array. Light modulation and display with high resolution can be realized in a limited area, and the display device is a novel transmission type micro display chip.

Description

technical field [0001] The present invention relates to the display field, in particular to a display device, a projection device, a near-eye display device and a forming method thereof. Background technique [0002] In the projection system, according to different projection principles, it can be divided into reflective projection system and transmissive projection system. Reflective projection system mainly includes: digital light processing projection display system (DLP projection display system) and liquid crystal on silicon projection display system (LCOS projection display system) . The transmissive projection system is mainly a liquid crystal display projection display system (LCD projection display system). [0003] DLP projection display system is divided into single-chip DLP projection display system and three-chip DLP projection display system, Figure 16 It is a structural schematic diagram of a three-chip DLP projection display system in the prior art, refer ...
