Lighting device, display device and near-eye display system

Abstract

The invention provides an illuminating device, a display device and a near-eye display system. The lighting device is arranged between the light reflection panel and the light beam collecting unit, wherein the lighting device includes: a light source; a light separation module, the light separation module receives the light emitted by the light source, and forms a A point lighting source arranged opposite to the panel, the point lighting source outputs incident light that can be transmitted to the light reflecting panel, and the light separation module is also used to receive reflected light reflected by the light reflecting panel from the incident light , transmitting the reflected light to the light beam collecting unit; wherein, the reflected light received by the light separation module surrounds the point illumination source. The illuminating device can solve the problem that the incident light beam and the outgoing light beam adopted by the prior art LCOS illuminating device cannot achieve a high energy rate and ensure a compact volume.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an illuminating device, a display device and a near-eye display system. Background technique [0002] Liquid Crystal on Silicon (LCOS) is a new type of reflective micro liquid crystal display (Micro Liquid Crystal Display, referred to as Micro LCD) projection technology, which uses a complementary metal oxide semiconductor (CMOS) coated with liquid crystal silicon Oxide Semiconductor (referred to as CMOS) integrated circuit chip is used as the substrate of reflective LCD. It is polished by advanced technology and then plated with aluminum as a reflector to form a CMOS substrate. Then, the CMOS substrate is combined with the glass substrate containing transparent electrodes Bonded, and then injected into the liquid crystal package to form an LCOS panel. [0003] At present, reflective liquid crystal on silicon is used in near-eye holographic technology. As a key device i...
