The color of LED electronic screen is inconsistent, and there are some questions about the pattern and color deviation between the modules on the side of the module. First of all, we need to understand the main factors that cause the color deviation of LED display module
LED electronic screen technology
1. After the wave soldering of the LED module, the orientation of the LED lamp bead has been fixed, so we don’t need to move it in this period of time. However, many companies do not have such maintenance conditions, so they often bump and bend LED lamp beads in the process of repairing, testing, welding pin, aging and handling;
2. Before pouring glue, the so-called arrangement becomes more and more simple, which leads to the disorder of lamp beads on the LED screen, and then leads to the occurrence of color deviation of the module.
Second, power supply when producing LED electronic screen
When many manufacturers plan the LED electronic screen, they can’t know what kind of materials (including the selection and consumption of power supply) they choose. The questions presented by the power supply system will lead to the uneven power supply of LED modules.
Third, the production of LED electronic screen control IC and control system
Most LED electronic screen manufacturers do not have the production conditions of LED electronic screen control IC, control system planning and development, testing. Therefore, the LED electronic screen produced by many manufacturers can not guarantee the quality, and the only thing they can do is to adjust the parameters of the LED electronic screen.
Fourth, the most important element of LED electronic screen is led beads
1. The inconsistency of the parameters of LED lamp bead chip;
2. Defects in the raw materials of the sealing glue;
3. The error of orientation when fixing the wafer;
4. Error in light and color separation.
These factors will affect the wavelength, brightness and viewpoint of the same batch of LED lights. Therefore, we have a very important process in the production of LED electronic screen, which is hybrid lamp. What is mixed lamp? Mixed lamp is to mix all LED lamps of the same color and then plug them into PCB. The advantage of this is that it can prevent the partial color deviation of LED module. How to deal with these questions? The suggestions and solutions given by Spyker Guangxu are as follows:
1. If it is in the production of LED electronic screen when the power supply problems, you need to replace the power lamp;
2. If it is in the production of LED electronic screen control IC or control system problems, we can only ask the supplier to solve;
3. If it is led beads or production technology caused by LED electronic screen module color bias, you can only repair or replace the module.
