What is the abbreviation for LCD?

LCD liquid crystal display is the abbreviation of Liquid Crystal Display. The structure of LCD is to place liquid crystals in two parallel pieces of glass. There are many vertical and horizontal thin wires between the two pieces of glass. The rod-shaped crystal molecules are controlled by whether they are powered or not. Change the direction and refract the light to produce the picture. Much better than CRT, but more expensive
LCD liquid crystal projector is the product of the combination of liquid crystal display technology and projection technology. It uses the electro-optic effect of liquid crystal to control the transmittance and reflectivity of the liquid crystal unit through the circuit, thereby producing different gray levels and as many as 1,670 million colors. beautiful images. The main imaging device of an LCD projector is a liquid crystal panel. The volume of an LCD projector depends on the size of the LCD panel, the smaller the LCD panel, the smaller the projector is.
According to the electro-optic effect, liquid crystal materials can be divided into two categories: active liquid crystal and inactive liquid crystal, among which active liquid crystal has high light transmittance and controllability. The liquid crystal panel uses active liquid crystal, and people can control the brightness and color of the liquid crystal panel through the relevant control system. Like LCD monitors, LCD projectors use twisted nematic liquid crystals. The light source of the LCD projector is a special high-power bulb, and the luminous energy is much higher than that of the CRT projector that uses fluorescent light, so the brightness and color saturation of the LCD projector are higher than that of the CRT projector. The pixel of the 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 the LCD projector is worse than that of the CRT projector.
LCD projectors can be divided into single-chip and three-chip types according to the number of internal liquid crystal panels. Most modern LCD projectors use three-chip LCD panels (Figure 1). The three-chip LCD projector uses red, green, and blue liquid crystal panels as the control layers for red, green, and blue light, respectively. The white light emitted by the light source passes through the lens group and then converges to the dichroic mirror group. The red light is first separated and projected onto the red liquid crystal panel. The image information represented by transparency “recorded” by the liquid crystal panel is projected into the image. red light information. The green light is projected on the green liquid crystal panel to form the green light information in the image. Similarly, the blue light passes through the blue liquid crystal panel to generate the blue light information in the image. The three colors of light are converged in the prism and projected by the projection lens to A full-color image is formed on the projection screen. Three-chip LCD projectors have higher image quality and higher brightness than single-chip LCD projectors. LCD projectors are small in size, light in weight, simple in manufacturing process, high in brightness and contrast ratio, and moderate in resolution. Now the market share of LCD projectors accounts for more than 70% of the total market share, which is the current market share. The tallest and most widely used projector.

What are the benefits of using LED movie screens in theaters?

The LED movie screens and image quality are good, the visual impact is strong, and people feel immersed in the scene. This is the common experience brought to us by movie viewing in the cinema. Up to now, people have regarded projection playback as the main way to watch movies. Laser projection It has also become an important technical symbol of the theater. However, development is the last word. The projection technology, which has been in the dominant position for many years, is now facing a strong enemy, the LED display screen, which has become in jeopardy. In March of

Why don’t cinemas popularize LED movie displays?

Speaking of movie theaters, many people must be familiar with it, because we usually go to see a movie with our family and friends when we are free. But you know what? Movies have a history of more than 100 years, and now with the advancement of technology, people’s movie viewing experience is getting better and better. But you know what? Many cinemas still use early projectors. Many people will ask, with our current science and technology so developed, why not use LED movie displays to replace projectors? Let’s discuss this issue today.The first is the question of size. In

Where do LED transparent displays fit in?

With the development of society, technology has become more and more advanced, especially in the LED display industry. In this development, with the continuous popularization of LED transparent displays in practical applications, transparent screens have become widely known. Although the transparent screen is an application of a new display technology, it still has a place in the market and shows a diversified trend through feedback and continuous improvement of user information. So what is a transparent screen? What is the use? Where is it used? LED transparent screen manufacturers explain! First,How about transparent led screen? The LED transparent screen is

How much is the LED floor tile screen per square meter?
