Abstract:
Large sized electronic displays may include a backlight that generates light to illuminate a display panel. The backlight is divided into tiles that each includes a set of backlight elements that are driven by respective tile driver circuitry. Based on receiving brightness data and/or control signals from a backlight controller (BCON) of the backlight, the respective tile driver circuitry drives corresponding backlight elements such that the backlight elements suitably illuminate the display panel.
