Abstract
The invention discloses a manufacturing method of a transmission-type silicon-based liquid crystal display. The method is characterized by comprising the following steps of: transparentizing a silicon-based substrate; manufacturing a colored color filter; manufacturing a liquid crystal sealing box; manufacturing a high-brightness backlight source; and performing micro-package on multiple layers of split components of a display device. The display manufactured with the method has the advantages of simple light path, compact structure, high reliability and the like, and is widely applied to the market fields of head-wear-type displays, video eyeglasses, micro-projection, photo printing machines and the like.
Description
technical field [0001] The invention relates to a liquid crystal display, in particular to a transmissive silicon-based liquid crystal display, in particular to a manufacturing method of a transmissive silicon-based liquid crystal display. Background technique [0002] At present, liquid crystal on silicon displays, namely LCOS (Liquid Crystal on Silicon), are all reflective liquid crystal devices, which have the characteristics of high integration, high resolution, and high aperture ratio of the device itself, and are widely used in the field of micro-display. [0003] However, this reflective liquid crystal on silicon needs to add an additional polarization beam splitter PBS device in the optical system, which is used to irradiate the light from the backlight to the surface of the LCOS device, and the reflected light is also projected to the screen or observed through the PBS device. If the eyes are closed, the light utilization rate of the entire optical path is reduced, ...
