| LCD (liquid crystal display) panels use liquid crystal filled grids, activated by electric fields, to create smooth, finely detailed images. The liquid crystal acts like a shutter that either blocks the backlight or lets it pass through to light up a particular color filter. The screen has hundreds of thousands of pixels that are charged or not charged, making them reflect or not reflect light to form images. LCD technology produces the same image as a CRT, but in a much smaller package. |

3LCD technology uses three high-temperature polysilicon liquid crystal panels.
White light is divided into red, green, and blue using special dichroic mirrors that transmit light with a certain wavelength.
The individual red, green, and blue colors are then passed through dedicated LCDs, before being combined together by a prism.
The image can then projected onto a screen. |
