Backlight flickering may be seen due to
Display image may look unstable if the on-duty ratio
electrical noise caused by Power Supply ability. is less than 5％.
Please check it with your actual set.
VBC should be set more than 1.0V.
Display image may look unstable if VBC is
less than 1.0V.
5) These signals can’t input at the same time.(Unused pin is to be left open.)
6) PWM pin has inrush current during PWM signal is to be high, this value depends on output impedance
of external device. For example, Pulse Generator with 50ohm output impedance has 27mA
PWM input current (IPWM) of this LED driver during 50μs.
7) Resolution of PWM signal has to be 256 at a maximum.
