LD71D1048C
SD-2003A
10 bit PWM controller / 48 Channel Output LED DRIVER
The LD71D1048C is LED driver / controller IC for LED display panel.
This is consisted of 48 channel LED driver , 10Bit PWM controller
and 48 bit shift register. Also it is very convenient to application
because all display data can be transferred by serial method.
