Abstract

This invention relates to an LCoS micro-display device using Micro LED as an external light source. It primarily comprises an LCoS micro-display for displaying and projecting image information of various types, including symbols, images, or text. The LCoS micro-display further includes an LCoS panel. A beam splitter or light guide plate is positioned in front of the LCoS panel, and a lens is positioned at the front end of the beam splitter or light guide plate. A light source, which is a Micro LED, is positioned on one side of the LCoS panel. The LCoS panel provides the image information, while the light source projects light. The light passes through the beam splitter or light guide plate and illuminates the LCoS panel, then is reflected by the LCoS panel and projected onto the lens.

Claims

1. An LCoS microdisplay device using Micro LED as an external light source, mainly comprising an LCoS microdisplay for displaying and projecting image information of various types, such as symbols, images, or text. The LCoS microdisplay includes: an LCoS panel; a beam splitter or light guide plate disposed in front of the LCoS panel; a lens disposed at the front end of the beam splitter or light guide plate; and a light source disposed on one side of the LCoS panel, the light source being a Micro LED. The LCoS panel is used to provide the image information, and the light source is used to emit light, so that the light passes through a beam splitter or light guide plate and shines on the LCoS panel, and then is reflected by the LCoS panel to be projected by the lens.

2. An LCoS micro-display device using Micro LED as an external light source, as described in claim 1, wherein, The light source is a micro-light-emitting diode array composed of multiple micro-light-emitting diodes.

3. An LCoS microdisplay device using Micro LED as an external light source, as described in claim 2, wherein, The grain size of the micro light-emitting diode is between 10x10um and 100x100um, and the spacing of the micro light-emitting diode array is between 10mm and 50um.

4. An LCoS micro-display device using Micro LED as an external light source, as described in claim 1, wherein, The beam splitter or light guide plate is a polarizing beam splitter (PBS).
