Abstract
An information handling display presents visual images in a privacy mode that manages visual image brightness with a local processing resource when a predetermined condition is detected, such as multiple individuals in the display field of view. For example, an information handling system provides visual information to a display timing controller that includes a pulse width modulation signal to command display backlight brightness. When in a privacy mode, the timing controller or another processing resource modifies the pulse width modulation signal to command a predetermined reduced brightness, such as in a range of 30 to 50 nits of reduced brightness.
