[QUOTE="David_AVD, post: 69714, member: 94"] The LED current is set by a resistor on each CC drive chip. I don't recall its number off the top of my head but did find a data sheet (in Chinese) for it. I'd have to check my code, but I think the OE is only disabled for a very short time (< 20 us at a guess) while the ABC select lines and latch are being changed after the data is clocked in for each scan row (every 1ms). That's why my setup was so much brighter and current hungry. I implemented dimming on a whole panel basic by using PWM on the OE line. [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
