The difference between the projector’s LCD and DLP seamless splicing screen projection

When consumers choose a projector, they usually encounter two keywords, LCD and DLP. What are the LCD and DLP seamless splicing screen projection technologies of the projector and what are the differences? Please see below. With the development of science and technology, projection technology has gradually entered the era of digital technology from LCD technology. Nowadays, the application of projectors has spread to all walks of life and came into being. There are also various brands in the technology market. For users who want to choose products, there is only one old saying: choose only the right ones, not the ones Dear. What are the LCD and DLP seamless splicing screen projection technologies of the projector? Here, I only use my personal understanding of the two major technologies of the projector to make some comments on the adaptation direction of the two types of technical products, so as to facilitate the majority of users to consider when choosing products. Liquid crystal technology is famous for its bright colors, lifelike images, high number of colors, and rich image levels. Suitable for multimedia, film and television, advertising and other industries. The disadvantage is that the light source loss is large, and the background color of the screen cannot achieve a pure white effect; after long-term use, the LCD panel is easy to age, the color is easy to attenuate, the imaging unit is larger, and the heat dissipation requirements are high. Therefore, the appearance of the LCD technology projector is general The

LCD Panel Type

The display screen can be divided into three types: normal temperature, wide temperature and ultra-wide temperature according to the supported working temperature range. The normal temperature display supports the working temperature between 0 °C and 50 °C, and the wide temperature display supports the working temperature between -20 °C and +70 °C. ℃, the ultra-wide temperature display supports the working temperature between -40℃~+90℃. Usually, the display screen with good low temperature performance will have poor high temperature performance. The wider the operating temperature range, the higher the price. Users can choose suitable display products according to actual use conditions.

How to make the LED display screen more high-definition

Improve the contrast of the LED display: Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer and more vivid the image, and the brighter and brighter the color. High contrast is very helpful for image clarity, detail performance, and gray level performance. Increase the gray level of the LED display: the gray level of the LED display refers to the brightness level that can be distinguished from the darkest to the brightest of the single primary color brightness. The higher the gray level of the LED display, the richer the color , The color is brighter; on the contrary, the display color is single and the change is simple. The increase of the gray level can greatly increase the color depth, making the display level of the image color increase geometrically. Nowadays, many LED display manufacturers can set the gray scale of the display to 14bit~16bit, so that the image level can distinguish the details and the display effect is more delicate, vivid, and colorful. Narrowing the dot pitch of the LED display: narrowing the dot pitch of the LED display can greatly improve the clarity of the display screen, because the smaller the dot pitch, the higher the pixel density per unit area of ​​the LED display, and the more details that can be displayed More, the screen display is more delicate and lifelike. The combination of LED display and video processor: The LED video processor can use
