What vdoes LCD means in LCD Projector?

Answer 1

LCD = Liquid Crystal Display

1. How a LCD Projector Creates The Image
2. To create the image, red, blue, and green light must be shown through their respective LCD screens, then brought together in a prism to form an image. This is done with the use of mirrors. As the light propagates from the metal halide lamp, it is shown through a dichroic mirror. This mirror only lets the red light through it but reflects the rest of the light. The rest of this light goes through another dichroic mirror that only lets the blue light through but reflects the green light. Hence, the red light is shown through a mirror and reflected into its LCD screen while the green light is reflected into its LCD screen. Then, the remaining blue light that passed through the second dichroic mirror is reflected a couple times into its LCD screen. Finally, the three colors are filtered by the gray scale images on the LCD screens to form the desired image, overlapped by the prism and projected onto a screen.
