Advantages of LED display


The indoor mid-to-high-end display market is dominated by DLP rear projection displays, but DLP technology has natural shortcomings. First of all, the 1 mm seam between display units that cannot be eliminated can swallow at least one display pixel. Secondly, it is also inferior to the direct-emitting LED screen in terms of color expression. What’s particularly inadequate is that due to the differences between DLP display units, it is difficult to control the uniformity of the color and brightness of the entire display. As the running time of the product increases, the differences between the units will become larger and larger. The seams are difficult to keep consistent and will become more and more obvious. The color difference between the units and the adjustment of the seams, even in the later maintenance and repair, are a relatively difficult task.

The biggest competitiveness of indoor high-density and small-pitch LED screen lies in the complete seamlessness of the display and the natural and true display colors. At the same time, in terms of post-maintenance, the LED screen already has a mature point-by-point correction technology. The display can be used for more than one or two years to perform a one-time correction of the entire screen with the instrument. The operation process is simple and the effect is very good. Therefore, to evaluate the two in terms of display quality, it must be that the high-density, small-pitch LED display is better than the DLP rear projection.

Small-pitch LED screen refers to indoor LED screen with LED dot pitch below P2.5, mainly including P2.5, P2.0, P1.8, P1.5 and other LED display products. With the improvement of LED screen manufacturing technology, the resolution of traditional LED screen has been greatly improved.

The small-pitch LED screen is the collective name for a whole set of systems, including LED display systems, high-definition display control systems, and heat dissipation systems. The small-pitch LED display adopts pixel-level point control technology to realize the state control of the brightness, color reduction and uniformity of the display pixel unit. The automatic reflow soldering process is adopted in the production process of the display screen, without manual post soldering.
