An LED driver is an electrical device which regulates the power to an LED or a string (or strings) of LEDs. An LED driver responds to the changing needs of the LED, or LED circuit, by providing a constant quantity
LED drivers, the electronics that operate LEDs, play an important part in preserving and enhancing the inherent LED qualities of clarity, speed, and efficiency.
The MAX7219/MAX7221 are compact, serial input/ output common-cathode display drivers that interface microprocessors (μPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. Included on-chip are a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM that ...

There are many LED display design parameters that can confuse designers when configuring the LED driver. This application note presents an emerging LED display end equipment example, an LED cinema screen, to help designers better understand and design the LED display screen system.
With continuing performance improvements and cost reductions, LEDs have quickly moved into larger media form factor (MFF) displays, replacing Cold Cathode Florescent Lamps (CCFL) for LCD back (edge or side)-lighting. MFF displays up to 19” may require up to 100 LEDs for proper backlighting.
