The fine pixel pitch LED display refers to an indoor LED display with an 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 display manufacturing technology, the resolution of traditional LED display has been greatly improved.

The fine pixel pitch LED display is a collective name for a complete system, including LED display systems, high-definition display control systems, and heat dissipation systems. The fine pixel pitch LED display adopts pixel-level point control technology to realize the state control of the brightness and color reduction and uniformity of the display unit. In the production process of the display screen, all automatic reflow soldering processes are adopted, and no manual post soldering is required.

The indoor mid-to-high-end display market is dominated by DLP rear projection displays, but DLP technology has natural flaws. First, the 1 mm joint between display units that cannot be eliminated at all can consume at least one display pixel. Secondly, in terms of color expression, it is also inferior to direct-emitting LED displays. What is particularly inadequate is that, due to the difference between DLP display units, the uniformity of the color and brightness of the entire display is difficult to control. It is difficult to keep the seam consistent, and it will become more and more obvious. The color difference between the units and the adjustment of the stitching, even if they are maintained and repaired at a later stage, are more difficult.
