During the use of LED display, the LED display is often not bright, and the packaging protection of LED display is not perfect, which leads to the damage of lamp beads during transportation, or the solder joints of LED display are virtual welded, and the LED light bar may not be bright. Let's take a look at the reason why the LED display is not bright.

Shenzhen Juxin Guang Cai Display Technology Co., Ltd. summarizes as follows:

Eight reasons why LED display screen is not bright

1, the solder mask of LED display circuit board is too thick, and the solder and circuit board can't be completely fused when soldering, which is also a virtual soldering phenomenon.

2. The solder joint of 2.LED display screen has the phenomenon of virtual soldering, and the vibration during transportation causes the solder joint to fall off, resulting in the light bar not being lit.

3. When the LED display screen is installed, the product is excessively squeezed, which leads to the damage of the LED display screen chip or the deformation and loss of solder joints.

4. The packaging protection of 4.LED display screen is not perfect, which leads to the damage of lamp beads during transportation.

5. When the LED display screen is installed, the bending angle is too large, which leads to the separation of the solder joint of the LED display screen from the copper foil, resulting in no light.

6. The amount of solder on the 6.LED display screen is small, and the solder joint is easy to fall off.

7. The 7.LED display screen should not be deformed during installation. If twisted, the solder joints of the LED display screen will fall off, resulting in dullness.

8. The solder quality of LED display screen is not good, and the solder joints of LED display screen are easy to crack and fall off during bending.

If it's about tin, you can add some tin or change the lamp bead. If there is damage or IC problem, you can send the module to our company and help you repair it for free.
