What is the difference between P2.5 and P2 of indoor high-definition LED display?

Aug 07,2021| LED Knowledge

The difference between P2.5 and P2 of the indoor high-definition LED display is reflected in many places. We all know that the LED display needs to be assembled by LED modules, and the two have the same size (320*160mm) module. In addition, the dimensions of other modules are different.

Let's take a look at their advantages, which can help us better understand their benefits in practice.
The indoor LED display is used in the studio.

Advantages of P2.5 indoor full-color LED display:

The surface mount is three-in-one, the red, green and blue chips are packaged in the same pixel, and they are evenly distributed to form a display screen.

Imported luminescent materials, high-quality IC chips, noise-free high-power power supply; full-screen fanless design, noise-free, low power consumption, can be used in the temperature range of 0 ℃ ~ 55 ℃.

With high-precision dimensions, the geometric shape and size design deviation between the cabinets is only 0.02 mm. Therefore, the unit cabinets are almost the same size, after assembly, the gap is uniform, the entire screen is very flat, the effect is good, and the quality is good.

It can support synchronous control card and asynchronous control card at the same time; even if the control computer fails, it can still display and play normally.

The display mode can be arbitrarily arranged by the user;

It can display text, pictures, charts, images, animations, and video information, and the amount of information displayed is not limited.

Using nonlinear correction technology, the image effect is delicate and clear; the animation effect is vivid and diverse, the video effect is smooth and lifelike, no bright spots, no screens, no dead spots, high brightness, low light decay, long life, and good quality.

I believe that after reading these two tables, you will be more clear about the difference between the indoor high-definition LED display P2.5 and P2. Of course, if you want to choose the correct LED display in the actual selection, you need to look at a variety of indicators, such as their material, welding quality and power-on test:

Material

1. P2 and P2.5 LED display panel:

Use cheap flame-retardant paper board or single-sided fiber board as the PCB circuit board of the LED lamp. Because all glass fiber PCB boards are very expensive. At the beginning, there is no difference. Under normal circumstances, it will break due to moisture, ultraviolet damage, oxidation and other reasons within a year, which will cause the entire LED unit board to be scrapped. High-quality Maipu brilliant LED display must use double-sided full glass fiber PCB board, although the cost is high, but the quality is guaranteed.

2. IC devices:

Observe whether the brands of IC devices used are consistent. What type of IC is used, and how many ICs are used, these are enough to affect the quality of the P2.5LED display. Some LED display manufacturers, in order to save costs, will deliberately reduce the number of ICs or mix other brands of ICs when producing cell boards.

3. Lamp beads and chips:

The naked eye cannot distinguish the quality of the lamp beads. It can only rely on long-term testing, which is called the aging test by experts. The general practice of full-color LED display manufacturers is: power on before leaving the factory to check whether the LED display can work normally, it will not go through a long aging test. Because there are time costs and labor costs.
Indoor LED display screens are used as decorations in the home.

Welding quality:

Check if there are any missing or mis-attached components on the patch, and if there is a short circuit of component pin burrs, check whether the solder joints of the straight plug-in unit are smooth and round, whether the board surface is clean and tidy, and there is no missing solder or missing solder, check the LED display light-emitting point The flatness of the array and the consistency of the ink color.

Power-on test:

① Power on to test the consistency of the luminous dot matrix;

② Power-on test whether the line drive tube is effectively protected;

③Electrically test the signal transmission capacity.
