at whose hand will the deer die? Watch the big PK between LCD splicing and DLP rear projection
The technological advantages and disadvantages of LCD splicing and DLP rear projection in PK
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 lifespan (usually 50000 hours of normal operation), no radiation, and uniform image brightness. At present, the largest LCD splicing unit can be as large as 60 inches, with small size, light weight, easy and fast installation, and small space occupation. But 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 cannot meet the true "seamless" splicing requirements.
DLP rear projection splicing, as the leader of traditional splicing products, has always dominated high-end industry applications with its perfect splicing and consistent and complete image height, which cannot be shaken by other splicing products. After adopting LED backlight, DLP has better image adjustability. On this basis, the advantages of DLP splicing are self-evident, with a minimum of 0.1mm and a maximum of no more than 1mm. Of course, DLP splicing also has its own shortcomings, such as low brightness, high power consumption, large size, and high maintenance costs in the later stage.
Comparison of advantages and disadvantages of crystal splicing and DLP rear projection in industry applications
The thickness of the LCD splicing wall can be easily controlled within 20 to 30 centimeters, which is incomparable to the thickness of 0.5 to 1 meter of DLP splicing technology. At the same time, ultra-thin design allows LCD splicing to be as consistent as possible with the wall design of the space, rather than having a large front protrusion. This aesthetic advantage is also sufficient to compete with DLP splicing. In most commercial markets, exhibition markets, and public spaces, space occupation is a huge cost and visual dissonance factor. LCD splicing, with its ultra-thin characteristics, has won a living space that DLP is difficult to squeeze into in these fields.
Compared with traditional DLP splicing products, LCD splicing also has a prominent advantage, which is the ability to invert the position, rotate, tilt and splice at any horizontal or vertical angle. Although DLP splicing can also be designed as products for vertical and inclined use, Samsung LCD splicing undoubtedly increases costs and affects market application and popularity. It can be said that until now, splicing at special angles is still dominated by LCDs.
Another major advantage of LCD splicing technology compared to traditional DLP splicing is its high light source utilization efficiency. This also determines that liquid crystal display units are easier to achieve higher display brightness. At present, high brightness LCD displays are no longer a fresh technology, and several domestic and international companies have launched them. By introducing splicing technology, high brightness LCD can also solve the bottleneck of screen size in outdoor applications, forming a very considerable LCD outdoor application market. In outdoor applications, the ultra-thin characteristics of LCD can also play a significant advantage. Due to the fact that outdoor applications are mostly suspended on the outer walls of buildings. So indicators such as volume thickness and unit weight are also more sensitive, which is another reason why DLP splicing products are difficult to enter the outdoor application market besides brightness factors.
