How does an LCD projector work?
This type of projector uses 3 LCD technology systems with the identical LCD displays which are used to form images in the watches and other electronic appliances. This system comprises of the three liquid displays where the image is formed through multiple processes. A light source depicts rays of white light which is moved through three mirrors which is specially configured to reflect a particular wavelength of light.
The mirrors emit blue, green and red wavelengths. An electrical signal is received whenever a beam of light is fed on to the LCD panel. The image is formed according to the signal which is instructed by the panels. The same image is formed in all the three LCD panels with different hues because of the colored light in the panel. The images are captured in a prism and forma a single image with 16.7 million colors. Finally the images are derived through the lenses for projection to the screen.
