Abstract:
Example implementations relate to inactive state backlight operation. In some examples, a system may include a display. The display may include a liquid-crystal display (LCD) panel and a backlight to illuminate the LCD panel. The system may include a computing device comprising instructions executable to disable the LCD panel from displaying a live image while the display is in an inactive state. The system may include a computing device comprising instructions executable to reduce an electrical current supplied to the backlight while the display is in the inactive state from a first amount of electrical current associated with the active state to a second amount of electrical current to cause the backlight to reach an operating condition within a targeted length of time from reentering the active state.
