Sub surface mounted module
Is a product between DIP and SMT, the LED lamp package surface and SMT, but its positive and negative pins and DIP, production is through PCB welding, LED screen module has made this kind of process is: high brightness, good display effect, the shortcoming is: complex process maintenance difficulties.
Three in one SMD
Refers to R, G, B three different colors of LED chip packaged in the same colloid, the advantages are: simple production, display effect is good, the drawback is: split color separation difficult, high cost
Three abreast to one SMD
Refers to the R, G, B three independent packaging SMT lights in accordance with certain spacing perpendicular together, so that not only has three in one all the advantages, but also to solve the three in one of the shortcomings
As can be seen above, these 5 different LED screen modules have different advantages and disadvantages, so when you customize the LED display, you should choose according to the actual application and the scene.

1, The installation of the LED display module, the requirements of the use of double-sided adhesive or wood glue, so that the module card slot and suction plate firmly affixed. In the use of double-sided adhesive, it is necessary to add a glass glue, or in the sun for a long time under the sun, will cause the mold off. Remember!

2, LED display module with low voltage input, so not without power supply and direct access to the 220V, otherwise it will cause the whole burnt LED Screen module. Remember!!

3, Blister word or arranged in the box body module, as far as possible by three points, four points, in line to make the whole word or the box body to form a loop, or a loop, i.e. each stroke at the end of the module according to the positive and negative electrode is connected with the two power line.

4, Switching power supply according to the characteristics of the LED display module to adjust the output voltage, please do not use the rotating voltage adjustment button.

5, LED special switching power supply. Power can only moisture, not waterproof, so the power supply must be waterproof measures.

The positive and negative points, there are 6 LED display module, power supply port wiring installation note must correspond to the positive pole and the negative pole, if the positive and negative reverse, LED display module does not light, and will not damage the LED screen module, as long as the switch to normal.

7, LED display module are used low-voltage input, the power supply is installed in the light-emitting LED display module within 10 meters.

8, The installation can not push, squeeze, pressure LED display module on the device, so as not to cause damage to the device, affecting the overall effect. Remember!

9, Single line length of 12~m, 15~m, respectively, according to the actual use of two. The bent connecting wire (including the unused connecting thread) is fixed on the blister bottom plate with the glass glue to prevent the shading.

10, In order to prevent the connection line is easy to fall off from the wire seat, the line seat design has a barb, if inserted in the inconvenience, should withdraw from the re insert. We must confirm the connection LED display module wire has been firmly seated, otherwise it will cause off day after.

11, There is no water treatment of the LED screen module, installed in the font or box, should prevent rainwater into the font or box.

12, LED display module spacing can be adjusted according to the requirement of the brightness, each square cloth point the best control in 50~100 group.

13, The power supply port outlet module series number not more than 50 groups, otherwise the tail module will be due to voltage attenuation, resulting in LED screen module brightness reduction. Although the formation of the circuit can avoid the occurrence of attenuation, but should not be connected to too many LED display modules.

14, The power line access to the box, must first through the four line or the three line and the corresponding group of four or group of modules connected. When the power cord enters the box, a large junction should be made to prevent the LED display module from being pulled out.

Optokingdom Engineer shares LED Display Module 7 Core Parameter Analysis

The LED display module is the core part of the display, it is equipped with a LED circuit board and the shell, and the LED lamp is arranged together are packaged according to certain rules, then add some water treatment and a product composition. With the continuous development of LED display industry and the growing demand for applications, the function and role of the LED display module can not be ignored.
full color led display screens
So, today we come to understand the LED display module under the seven parameters:

1.LED panels module color

It is the most basic parameters in the LED panels module, the application of different colors in different occasions. According to the variety of colors can be divided into single color, full-color single point of control of two.

1), monochromatic is a single color, can not be changed, then the power can work.

2), full color is single point to each module can control the color, to achieve a certain degree of time can display pictures and video effects on the number of modules. To add a full-color single point control system can realize the effect.

2.LED display module brightness

One to the brightness, we think of the word high brightness, this parameter is a parameter that people pay more attention to. Brightness in the LED inside is a complex problem, we usually say in the LED display module brightness is usually luminous intensity and transparency, is generally related to the degree of each module can be summed up.

3.LED display module light angle

No LED display module with lens light angle, mainly by the LED lamp to decide different light angle LED lamp emitting angle is different, generally provided by the manufacturer for LED lamp module angle.

4.LED display module operating temperature

The normal working temperature of the LED screen module is usually between -18 C and 58 C, if the requirements are relatively high, it is necessary to carry out special treatment, such as air conditioning or exhaust fan.

5.LED screen module voltage

It is one of the most important parameters in the LED screen module, and the low voltage module of 12V is more common. In connection with the power supply and control system must check the correctness of the voltage value, in order to power, otherwise it will damage the LED module.

6.LED module size

Usually refers to the length and width of the higher dimensions.

The maximum length of a single connection: this parameter when we do large projects with more than, it means in a series LEDscreen module, a LED screen module is connected. This is related to the size of the connection line of the LED display module. Also according to the actual situation to customize.

7.LED module waterproof level

This is mainly for outdoor, it is to ensure that the LED display module can be an important indicator of long-term work in the open air. Usually in the case of open air the best waterproof level to reach IP65.
