is led display module universal?-欧洲杯外围平台

i have done led packaging and led product applications. if the materials used for led packaging (support, glue, chips, etc.) are different, the color of the led will be different. generally, the manufacturer will make one or two more for large displays spare. if there is no spare.

you can ask the installation unit to send someone over to fix it, but if they confiscate the money, they probably won't bother to care about you.

or find a module with a similar color and install it on the corner. it doesn't look so obvious.
