LED Product Development Process
Rental led display spreads rapidly and cause great attention, because of led products’ great number of advantages. For example: high brightness, low voltage, low power consumption, ease of integration, driving a simple, long life, impact resistance and stable performance, and its extremely broad development prospects. Current is moving higher brightness, higher weather resistance and luminous density, light uniformity, full color development.
