Some buyers will complain that the led sign bought is not clear, and the LEDs are very clear, which destroys the beauty of the picture.
Look at the picture, the original picture is like this, the actual display is like this. This problem is related to the distance between the led sign pixels, and the smaller the distance, the clearer. It is also related to the viewing distance, and the farther the distance is, the clearer it is. In the store for led sign product, if you use a small distance product, it will effectively improve the graininess. If you use P3, P2 LED modules, It has a good viewing effect at a distance of 5 meters. For the P3 product, because it requires too many LEDs, the cost is very high, and the price of the 39inx14in size will exceed $900. The pixel distance is small, there will be another problem. Because there are too many LEDs in a small area, many drivers are needed, they will emit a lot of heat. In order to solve the problem of heat dissipation and power supply, the brightness of the LED is Will be lowered. Generally used only for indoor use. The viewing distance of the P4 module is about 7 meters, and the viewing distance of the P5 is about 10 meters. The person standing outside 10 meters, the P5 module cannot see the led particles. However, if standing in front of the LED display and the viewing distance is less than 1 meter, the P2 LED also has a grainy feel. Buyers need to understand the viewing distance of LEDs when purchasing LED signs and have appropriate choices for the pixel spacing of LED signs.
