Has anybody any info about the SM16227 (16237) type shift driver?
It is in some way similar to the FM6124 as it has brigthness control, but it’s brightness control is only 5 bits and the setting method is unfortunately unknown to me. I’ve found only a Chinese data sheet (http://www.88869188.com/uploads/201805/5afbd772d273c.pdf) and haven’t find any clue how to set the brightness level correctly. My problem is that after power up, sometimes it is set randomly, so different panel regions has different brightness levels. I need to elliminate this. Any info is wellcome!
