Explore the market development situation through the technological battle between LCD and DLP

In the current large-screen splicing market, people always unconsciously compare ultra-narrow bezel LCD splicing with DLP splicing. For a long time, DLP rear projection has occupied a large share of the large-screen splicing market. With the continuous growth of the LCD splicing market, the first challenge is the traditional DLP rear projection splicing. Especially in the past two years, the two major technologies of LCD and DLP have respectively achieved significant breakthroughs in their respective fields, and the market competition has become more intense. A showdown between LCD splicing and DLP rear-projection splicing: How will they win or lose?

Who will come out on top? Take a look at the showdown between LCD splicing and DLP rear-projection

A comparison of the technical advantages and disadvantages between LCD splicing and DLP rear projection

LCD splicing is a new splicing technology that has emerged in recent years. LCD splicing walls have the advantages of low power consumption, light weight, long service life (generally can work normally for 50,000 hours), no radiation, and uniform picture brightness. At present, the largest LCD splicing unit can be as large as 60 inches. It is small in size, light in weight, easy and quick to install, and occupies less space. However, its biggest drawback is that it cannot achieve seamless splicing. Although through continuous efforts, the DID splicing screen has been reduced from the initial 1-2 centimeters to the current 5.3 millimeters, this level still fails to meet the true requirement of "seamless" splicing seams.

As the leader of traditional splicing products, DLP rear-projection splicing has always dominated high-end industry applications with its perfect seams and consistent and complete picture height, which is unshakable by other splicing products. After adopting the LED backlight, the DLP has even more outstanding picture adjustability. On this basis, the seam advantage of DLP is self-evident. The minimum can be controlled within 0.1mm, and the maximum will not exceed 1mm. Of course, DLP stitching also has its own drawbacks, such as low brightness, high power consumption, large size, and high maintenance costs in the later stage.

The thickness of the LCD splicing wall can be easily controlled within 20 to 30 centimeters, which is incomparable to the 0.5 to 1 meter thickness of the DLP splicing technology. Meanwhile, the ultra-thinness enables the LCD splicing to be as consistent as possible with the wall design of the space, rather than protruding significantly forward. This aesthetic advantage is also sufficient to make it compete with DLP splicing. In most commercial markets, exhibition and display markets, and public space applications, the occupation of space is a huge cost and a visually discordant factor. With its ultra-thin characteristics, LCD splicing has won a survival space that DLP finds hard to break into in these fields.

Compared with traditional DLP splicing products, LCD splicing also has a prominent advantage, that is, it can be freely reversed in position, rotated, and placed and spliced at any horizontal or vertical Angle. Although DLP splicing can also be designed to be used vertically or at an Angle, this will undoubtedly increase the cost and affect the market application and popularization. It can be said that up to now, the splicing at special angles is still dominated by LCD.

Another major advantage of LCD splicing technology compared with traditional DLP splicing is its very high light source utilization efficiency. This also determines that the liquid crystal display unit is more likely to achieve a higher display brightness. At present, high-brightness liquid crystal displays are no longer a novel technology. Several domestic and international enterprises have launched them. By introducing splicing technology, the application of high-brightness LCDS outdoors can also solve the bottleneck of picture size, forming a very considerable outdoor application market for LCDS. In outdoor applications, the ultra-thin feature of liquid crystals can also bring significant advantages. Since outdoor applications are mostly suspended on the outer walls of buildings. Therefore, indicators such as volume thickness and unit weight are also more sensitive. This is another reason why DLP splicing products, apart from the brightness factor, are difficult to enter the outdoor application market.

Another brand-new application method of LCD splicing display still cannot do without the thin and light characteristics of LCD units.
