OVERVIEW
THEORY
The three light beams pass through Condensing Lenses (C-Lens) which focus the light to match the size of the LCD panel.
Then the three light beams are joined together to form white light, which is then projected to the viewing screen.

Condensing Lens: (C-Lens) focuses the light to match the size of the LCD panel.
Dichroic Prism: The prism consists of two Dichroic Mirrors. One reflects red light forward and the other reflects blue light
forward. Both allow green light to pass through. Once the light is joined, it is projected onto the viewing screen.

Fresnel Lens: Mylar screen that condenses/focuses
the light from projection lens.
Lenticular Lens: Focuses the light through the
openings in the Black Stripe layer.
Black Stripe: Improves contrast by blocking outside
light.
Diffusion Plate: Improves viewing angle by diffusing
the light.
Hard Coat: Protects the screen surface and helps
improve contrast.
