LED Display facts
What Does 'LED' Mean?
LED stands for Light Emitting Diode. It produces light through electric luminescence without heating a metal filament, making it energy-efficient and power-saving. LEDs consist of durable solid materials and emit almost no heat. Invented by Oleg Losev in 1927, the first LEDs were infrared, red, and yellow. The efficient blue LED was introduced by Shuji Nakamura in 1994, paving the way for modern white and green LEDs.
Unpacking SMD Technology
SMD stands for Surface Mount Device, referring to electronic components mounted directly on circuit boards. In LED displays, it means red, green, and blue diodes are encapsulated in plastic and surface-mounted, allowing for higher resolution as the diodes take up less space.
What is Nits & EMC?
Brightness Demystified: What are Nits?
Nits measure the luminance of an LED display and are equivalent to candelas per square meter. This unit considers the human eye’s perception of brightness and differs from ANSI lumens, which measure video projector brightness. One candela approximates the light from a standard candle.
Understanding EMC: What is EMC?
EMC stands for Electromagnetic Compatibility, focusing on the radiation emitted by electrical devices. The EU’s EMC Directive ensures devices do not interfere with each other’s performance, crucial in sensitive environments like airports and hospitals. All Expromo displays comply with this directive.
