What is the better difference between P3 and P4 led displays?

P4 is better.

1, in terms of display effect, the point density of P3 is greater than that of P4 display screen, so the display content will be clearer;

2. In terms of price, P3 is higher than P4, so there will be some advantages in cost performance.

3. The nearest sight distance of these two products should not be closer than 4m, otherwise the graininess will be very heavy. If it is used for indoor close-range display, it is recommended to make a series of display screens with small spacing. Of course, the price will increase by another level.

4. If it is used to play some promotional videos or advertisements, the viewing distance is relatively long, and P3 and P4 have similar effects.

Common sense of LED display maintenance

First of all, clarity

For the display screen with low protection level, especially the outdoor display screen, the dust in the atmosphere will enter the equipment through the vent hole, which will accelerate the wear and even damage of the fan and other equipment. Dust will also fall on the surface of the internal control device of the display, reducing the thermal conductivity and insulation performance. When the weather is wet, dust will absorb moisture in the air, causing short circuit. It will also lead to long-term mildew of PCB and electronic components, which will lead to the degradation and failure of equipment technical performance.

Second, tighten.

LED display screen is a kind of high power consumption equipment. After running for a period of time, due to repeated start and stop, the terminals of the power supply part will be loose due to cold and heat, and the contact will not be firm, forming a virtual connection. In severe cases, it will heat up and even ignite nearby plastic parts. The signal terminal will also loosen due to the change of ambient temperature, and the erosion of moisture will lead to poor contact and equipment failure. Therefore, the connection part of LED display screen must be tightened regularly.
