LCD
LCD is the abbreviation of liquid crystal display. The structure of LCD is to place liquid crystal in two parallel pieces of glass. There are many vertical and horizontal small wires between the two pieces of glass. The direction of rod-shaped crystal molecules can be controlled by power on or not, But the price is more expensive.

What is the abbreviation of LCD?

LCD projector is a combination of liquid crystal display technology and projection technology.
it uses the electro-optic effect of liquid crystal to control the transmittance and reflectance of liquid crystal unit through circuit, The size of the LCD projector depends on the size of the LCD panel.
the smaller the LCD panel, the smaller the size of the projector.

according to the electro-optic effect.
liquid crystal materials can be divided into active liquid crystal and inactive liquid crystal, The active liquid crystal has high light transmittance and controllability.
the active liquid crystal is used in the liquid crystal panel.
people can control the brightness and color of the liquid crystal panel through the relevant control system.
it is the same as the liquid crystal display.
the LCD projector uses twisted nematic liquid crystal.
the light source of the LCD projector is a special high-power bulb.
the luminous energy is much higher than that of the c-lamp using fluorescent light RT projector, so the brightness and color saturation of LCD projector are higher than that of CRT projector.
the pixel of LCD projector is the liquid crystal unit on the liquid crystal panel.
once the liquid crystal panel is selected, the resolution is basically determined, so the function of adjusting the resolution of LCD projector is worse than that of CRT projector.
the function of adjusting the resolution of LCD projector is better than that of CRT projector
.
LCD projectors can be divided into single chip and three chip according to the number of internal LCD panels.
most modern LCD projectors use three chip LCD panels (Figure 1).
three chip LCD projectors use red, green and blue LCD panels as red, green and blue LCD panels respectively The white light emitted by the light source passes through the lens group and converges to the color separation mirror group.
the red light is first separated and projected onto the red liquid crystal panel, and the image information "recorded" by the liquid crystal panel is projected to generate the red light information in the image.
the green light is projected onto the green liquid crystal panel.
the green light information in the image is formed, Similarly, the blue light information in the image is generated by the blue liquid crystal panel, and the three colors of light converge in the prism and are projected onto the projection screen by the projection lens to form a full-color image.
the three chip LCD projector has higher image quality and higher brightness than the single chip LCD projector.
the LCD projector has smaller volume and lighter weight.
the manufacturing process is simple, With high brightness and contrast, and moderate resolution, LCD projectors now occupy more than 70% of the total market share, and are the most widely used projectors in the market.
