The contrast to LED screen is 1000 : 1 ; The flatness coefficient of the box is less than 0.5mm , and the power factor is more than 88% ; Air conditioning can not be used for refrigeration ; LED display control card , also known as LED asynchronous control system or LED electronic display control ca

Mini led to refer to the size of 100 μs The size of M-class LED chip is between small spacing led and micro led , which is the result of further refinement of small spacing led . Among them , small spacing led refers to the LED backlight or display product of the spacing between adjacent lamp beads

A small spacing LED display that is qualified and can stand the test must have been strictly tested before leaving the factory. Only in this way can we ensure the normal operation and good display effect for a long time and reduce the failure rate after being officially delivered to the customer.2、
