The present invention provides a method of unit level liquid crystal display device assembly process for liquid crystal on silicon. It starts with sawing silicon wafer and ITO glass substrate. Then good silicon dies and ITO glass dies will be picked and transferred to separate carriers. Alignment layers will respectively be coated on each silicon die and ITO glass die after cleaning. Then there are two options for the following steps. In method one, silicon die and ITO glass die lamination comes after coating frame adhesive. Then frame adhesive is cured. The liquid crystal will fill the cell and then seal the fill port. Die mounting, wire bonding and encapsulation will come along with external ITO connection to call it an end. In method two, frame adhesive precedes internal connection and LC one drop fill. Then silicon die and ITO glass die are laminated before frame adhesive cure. Afterwards die mount, wire bonding and encapsulation come last.

A see-through near-to-eye viewing optical system, which can be used in a head-mounted augmented reality display system, is provided. The see-through near-to-eye viewing optical system of the present invention comprises an LED illumination system for generating a light and a pre-polarizer for concentrating said light onto a PBS. Then an LCOS panel receives and reflects said light towards a post-polarizer after generating an image. The light travels from the post-polarizer and passes through an eyepiece for magnifying the image, and continues towards a 50/50 beam splitter. Afterwards the beam splitter transmits said light and another light from the outside field of view to users eyes simultaneously and thus, the user can see what is shown on the glass screen while still being able to see through it.

A head up display system comprises an optical projector, a projection screen, a combiner, a driver system board, an event data recorder, a front image sensor and a rear image sensor. The optical projector is a front projector or a rear projector for projecting the image onto the projection screen. Then the combiner projects a virtual image from the image of the projection screen within two to three meters behind the combiner and thus, drivers are able to observe the environment outside the car and to read the information provided by the head up display system simultaneously. The driver system board can connect to a drivers smart phone through wire (such as HDMI/MHL) or wireless (such as WiFi) and thus, an image from real-time contents of the smart phone or an image from other functions of the smart phone can be transmitted to the driver system board and projected by the optical projector for drivers watch or use. The event data recorder and the front image sensor can record the driving information and traffic information and save them into a built-in memory or a Secure Digital Memory Card. The front image sensor can record the brightness outside a car so that a luminous flux of the optical projector can be adjusted automatically through the driver system board and thus, drivers are able to watch the images clearly on the head up display system under any circumstances. Meanwhile the event data recorder and the rear image sensor can record driving information and inside information and save them into a built-in memory or a Secure Digital Memory Card. The rear image sensor supports finger movement sensing technology to input instructions without finger contact or touch, and the inputted instructions will be transmitted to the drivers smart phone after being processed by the driver system board so as to operate the smart phone.
