Emulating 16bit resolution for better LED intensity control in a video display

Posted: 09 Jul 2010     Print Version  Bookmark and Share

Keywords:LED intensity  video display  emulating 16bit resolution 

When a video display application uses the MAX6975 PWM LED driver, more PWM resolutions are needed to provide gamma (visual effect) correction, LED characteristic matching, and ambient light adjustment to the 8bit or 10bit video information. This application note explains how to emulate 16bit PWM resolution for the video application by using the MAX6975 with a native PWM resolution of 14bits.
