Small pitch LED display
The small-pitch LED display refers to the indoor LED display with the LED dot pitch below P2.5.
The small-pitch LED display refers to the indoor LED display with the LED dot pitch below P2.5. With the improvement of LED display manufacturing technology, the resolution of traditional LED display has been greatly improved.
Small-pitch LED display is a collective term for a complete system, including LED display system, high-definition display control system, and cooling system. 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. In the production process of the display screen, all automatic reflow soldering processes are adopted, without manual post-soldering.
Small-pitch LED screens are mainly aimed at the indoor high-end display market, and this field is still dominated by DLP rear projection display. However, DLP technology has natural defects. First, the 1mm seam between display units cannot be eliminated at all. Eat at least one display pixel. Secondly, it is inferior to the direct-emitting LED display in terms of color expression. What is particularly insufficient is that due to the differences between DLP display units, it is difficult to control the uniformity of color and brightness of the entire display screen. With the increase of product running time, the differences between units will become larger and larger. Seams are difficult to keep consistent and will become more and more noticeable. The color difference between the units and the adjustment of the seams are relatively difficult even for maintenance and repairs in the later stage.
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 real. At the same time, in terms of post-maintenance, LED display screens already have mature point-by-point calibration technology. Display screens that have been used for more than one or two years can be calibrated with an instrument for one-time calibration of the entire screen. The operation process is simple and the effect is also very good. Therefore, if we 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.
