This paper introduces what is dlp large screen splicing technology and its principle and characteristics.

Dlp large screen splicing is a customized product, and the size of the product can be made according to the needs of customers. Compared with the traditional screen mode of splicing small screens together, dlp large screen splicing has the characteristics of high definition. Dlp large screen splicing is often used in security. The installation principle and product structure of dlp large screen splicing are different from the traditional ones, and the later maintenance cost is also very low. The following small series will introduce you to the principle and characteristics of dlp large screen splicing.

What is dlp large screen splicing?

A large screen without splicing means that the whole screen consists of a whole screen without any gaps or physical splicing. It has the characteristics of seamless, arbitrary custom size, integrated image and ultra-high-definition picture. It can realize a variety of large-screen functions that can be changed from large to small: single-screen split display, single-screen independent display, arbitrary combination display, vertical display, optional compensation or coverage of image borders, support roaming, scaling and stretching digital signals, set and run various display plans, and process full HD signals in real time, providing you with a high-definition, high-brightness, high-resolution and high-stability high-definition large-screen display and control system, and bringing you a seamless visual experience.

Principle of dlp large screen splicing

Specifically, dlp projection technology uses digital micromirror chip (dmd) as the main key processing element to realize digital optical processing.

Its principle is that the cold light source emitted by the ultra-high pressure bulb passes through the condenser lens, and the light is homogenized by the rod. The processed light is divided into three primary colors of rgb through the color wheel, then projected onto the dmd chip through the lens, and finally reflected by the projection lens to form an image on the projection screen.

Dlp splicing wall is formed by splicing multiple rear projection display units. Its main feature is that the seam is small, and its minimum seam can reach several tenths of a millimeter, which can achieve real "seamless" splicing, which is beyond the reach of the other two technologies, lcd and pdp.

Of course, dlp splicing also has its shortcomings. Because the light source of dlp splicing comes from the light bulb, it has high power consumption and large heat dissipation, and the brightness will decrease after a period of use, which makes users have to constantly change the light bulb to maintain the initial display effect, and its unit box is large, which will bring some troubles during installation. , which brings inconvenience to users.

However, with the continuous development of splicing technology, dlp splicing has solved a series of problems such as frequent replacement of light bulbs, high power consumption and high heat dissipation, all of which benefit from the addition of led light sources. After using led light source, dlp splicing unit not only has a great breakthrough in service life, but also has revolutionary changes in color and power consumption, so that dlp splicing can continue to maintain its leading position in the market.

Characteristics of dlp large screen splicing

1, visually, there is no physical gap, the picture consistency is good, and the whole screen can be cut to the required size.

2. The picture definition is high, and the input resolution supports from 640x480 to 1920x 1200 pixels; The output resolution supports from 640x480 to 1920x 1200 pixels.

3. dlp large screen without splicing occupies much less space than other similar products, and there is no need for maintenance channel behind it.

4, barrier-free work, low maintenance cost;

Dlp jointless large screen optical machine adopts UHP light source. Because the display area of a single optical machine is relatively large, the number of optical machine units is small and the cost is low. For example, a large screen with width * height of 4.8m * 1.8m needs 8 pieces of 4*2 for a 60-inch splicing screen. No splicing Dlp large screen only needs two optical machines, and only two light sources need to be replaced at a time. So? The maintenance cost of dlp large screen products without splicing is not high.

5. The size of dlp large screen without splicing can be flexibly set; Bitter Company has set up a professional design team, which can design a large-screen display system with the best cost performance according to the size of installation space or the needs of the owners. The length is not limited, and the height can be designed to the most reasonable size according to the requirements of the other party. ?

The above small series introduces the principle of dlp large screen splicing, the characteristics of dlp large screen splicing and its advantages in the product market. The market space of dlp large screen splicing is very large. Compared with some mainstream products we use now, dlp large-screen splicing has the characteristics of small floor space and convenient later maintenance, and the picture quality is better. These are the reasons why dlp large screen splicing will have a huge market. If you want to develop dlp large screen splicing, please learn more.
