Small-pitch LED display refers to indoor LED display 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 display manufacturing technology, the resolution of traditional LED display has been greatly improved.
The small-pitch LED display 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.

Performance characteristics of small-pitch LED display
1. Energy-saving: It is a cold light source, relying on semiconductors to emit light, ultra-low power, 1000~2000 lumens/watt, light source life of 10,000 hours, and light attenuation of 5%~10%. Semiconductor lighting itself does not pollute the environment. Compared with other full-color LED displays, the power saving efficiency can reach more than 95%. Under the same brightness, the power consumption is only 1/10 of that of ordinary incandescent lamps and 1/2 of that of fluorescent tubes.

2. Health: It is a green light source. DC drive, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong light-emitting direction; good dimming performance, no visual error when color temperature changes; cold light source generates low heat , Can be touched safely; these are not achieved by incandescent and fluorescent lamps. It can not only provide a comfortable light space, but also meet people's physiological health needs. It is a healthy light source that protects eyesight and is environmentally friendly.
3. The small-pitch LED display has small size, light weight, epoxy resin encapsulation, can withstand high-strength mechanical shocks and vibrations, is not easy to break, and has an average life of 200,000 hours. The maintenance cost of the lamps avoids the pain of frequent lamp replacement, which can be described as "one-time-for-all"
4. Practicability of small-pitch LED display
It can ensure normal lighting use, ensure hygienic use, protect eyes, and protect eyesight. The light color has no abnormal psychological or physiological reactions, the lamps are firm, and the line safety switch is flexible. In a sense, the decorative nature of the small-pitch LED display is also practical, otherwise, the issue of decorativeness will be out of the question. For example, the use of lamps and lanterns to decorate the room, people will relax physically and mentally while appreciating, this kind of lighting effect reflects the actual value of decoration.
5. The decorativeness of the small-pitch LED display
The small-pitch LED display screen is one of ornamental, the material of the lamp is beautiful, the shape is unique, the color is more novel and beautiful; the other is the coordination, the form of the display screen is carefully designed, coordinated with the room decoration, and matched with the furnishings, the material of the lamp shape and the furniture The consistency of the body and material can reflect the host's artistic conception; the third is to highlight the individuality and the color of the light source to create a certain atmosphere according to people's needs, such as warmth, calmness, comfort, tranquility, and peace. Highlight the particularity of the owner's requirements for lighting and reflect different personalities. On the premise of ensuring the use of light, giving people a beautiful artistic enjoyment, this is the unified combination of the practicality and decoration of the lighting; specific to each piece of lighting, there is emphasis on lighting, some emphasis on decoration, and both . When choosing, it is necessary to consider the characteristics of different personnel, different uses and interior decoration requirements.

Advantages of small-pitch 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 cannot be eliminated, which can swallow at least one display pixel. Secondly, it is also inferior to the direct-emitting LED display in terms of color expression. A particularly shortcoming is that due to the differences between the DLP display units, the uniformity of the color and brightness of the entire display is difficult to control. 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 displays 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 display already has a mature point-by-point calibration technology. After using the display for more than one or two years, the instrument can be used to perform a one-time calibration of the entire screen. 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.
