Causes and solutions for color cast in LED displays!

What is the problem with color cast in LED display? What should we do if the color cast problem occurs? Let me explain it to you below!

The reason why the LED display screen turns yellow is that the baking temperature is too high or the time is too long, and the proportion of glue is wrong. Glue A tends to turn yellow easily. Solution: AB glue solidifies and demolds within 30 minutes at 120-140 degrees. It is easy to yellow when baked above 150 degrees for a long time.cog led AB glue is cured and demoulded at 120-130 degrees/30-40 minutes. It will turn yellow if it exceeds 150 degrees or is baked for a long time. When making large lamp holders, lower the curing temperature.

If there is a bubble problem in the LED display lamp bead, the cause is: bubbles in the bowl: the bracket is poorly dipped in glue.outdoor lcd digital signage Bracket bubbles: The curing temperature is too high and the epoxy cures too aggressively. Cracked glue and roof explosion: The curing time is short and the epoxy resin is incompletely or unevenly cured. AB glue has exceeded its usable time. Bubbles on the surface of the lamp holder: The epoxy glue has difficulty in degassing or the user does not use enough vacuum and the glue preparation time is too long. The solution is to improve the process or contact the epoxy supplier depending on the usage.

The reason why the LED display bracket is glued is that the uneven surface of the bracket causes capillary phenomena.ips vs ads panel AB glue contains volatile materials. You can't solve it at this time and need the supplier to exchange the goods.

If the LED display package discolors after being released from the mold after being baked for a short period of time, the main reasons are: the stacking in the oven is too dense and the ventilation is poor. The local temperature of the oven is too high. There are other color contaminants in the oven. The solution: improve ventilation. Remove color stains and confirm the actual temperature in the oven.

Some of the lamps on the same row of brackets are colored or have different gelling times and uneven quality. This is usually due to insufficient stirring. The solution is: stir thoroughly and evenly, paying special attention to the corners of the container.
