There are too many types of led displays. If you don't know much about led displays, you really don't have the concept of three-in-one, three-in-one full-color LED displays in your head.

Let's first look at the explanation of three-in-one and three-in-one:

1. What is a three-in-one surface sticker

It refers to the combination of red, green and blue three light-emitting points packaged in the same light-emitting tube. Since they are packaged in the same light-emitting tube, they are one point in close proximity and one line is separated. The price of the three-in-one is high, and the best ones are Riya, Osram and CREE.

2. What is a three-and-one table post (separate table post)

It means that the three light-emitting points of red, green and blue are packaged separately, and after packaging, they are arranged into a pixel point like those of the sub-surface patch.

Then we look at the difference between three-in-one and three-in-one full-color LED display:

Compared with three and one, 1. three-in-one has low power consumption, good heat dissipation, effectively prolonging the life of the screen, and high reliability. Because three and one are separate surface stickers, three separate power supply

2., the three-in-one maintenance cost is lower than that of the three-in-one, because the three-in-one can realize the maintenance of a single lamp.

3., the three-in-one has better color uniformity and no granular feeling, because the three-in-one surface can be treated with diffuse reflection light. In addition, the viewing angle of the whole screen is larger than that of the three-in-one.

4. usually, the three-in-one full-color screen is easier than the three-in-one full-color screen, and the color saturation is high.

5. in general, the three and one packaging costs and production costs are much lower than the three-in-one.

6., the three-in-one full-color screen is more uniform in overall color than the three-in-one, because the three-in-one uses the whole surface to emit light, while the three-in-one is only limited to point light.

7., the temperature of the three-in-one IC and the driver chip is lower than that of the three-in-one, thus improving the overall life of the screen body.

8., from the welding process, the packaging method of the three-in-one surface mount is very mature, which is better than the three-in-one surface mount.

9., due to the complex steps in the three-in-one surface mounting process, the construction period is longer. The construction period of three and one is the production date of normal production display screen.

10. are usually three and one with a mask protection, which can achieve dust prevention, sun protection, and can achieve the effect of protecting the light-emitting chip, while the three-in-one is that the light-emitting chip is directly exposed without any mask protection.

Due to the high price of the three-in-one table sticker, it is mainly used for export. It is believed that with the gradual reduction of the cost of chip processing, the three and one will meet the needs of users well with its extremely high cost performance, while the Asian surface stickers will withdraw from the market in the near future.
