The indoor mid-to-high-end display market is dominated by projection screen displays, but projection screens have natural defects. First of all, the 1 mm seam between display units that cannot be eliminated at all can devour at least one display pixel. Secondly, it is also inferior to the direct-emitting LED display in terms of color expression. In particular, due to the differences between DLP display units, it is difficult to control the uniformity of color and brightness of the entire display screen. Seams are hard to keep consistent and will become more and more noticeable. The color difference between the units and the adjustment of the seam, even if it is maintained and repaired in the later stage, are a more difficult thing.
The biggest competitiveness of indoor high-density small-pitch LED display is that the display is completely seamless and the display color is natural and true. At the same time, in terms of post-maintenance, the LED display screen already has a mature point-by-point correction technology. The display screen that has been used for more than one or two years can be corrected by the instrument at one time. The operation process is simple and the effect is also very good. Therefore, if the two are evaluated in terms of display quality, it must be that the high-density small-pitch LED display is better than the DLP rear projection.
Features
As the name implies, the characteristics of small-pitch LEDs are that the dot pitch of the screen is small, and the resolution per unit area is high. It can display higher-definition graphics images and videos, as well as more channels of video and image images, especially in the application of image splicing, which can achieve seamless and arbitrarily large-area splicing. Of course, in order to achieve the ideal display effect, the small-pitch LED display cannot do without the auxiliary role of the video processor.
