A multi-pixel display panel can display an image that includes an informational element. A multi-element backlight panel can backlight the display panel. A controller coupled to the display panel and the backlight panel can control the backlight panel to illuminate the informational element more brightly or more dimly than portions of the image away from the informational element. In some examples, the controller can illuminate personal information more dimly than portions of the image away from the personal information, which can provide privacy for a user. In some examples, the controller can illuminate a prompt for a user action more brightly than portions of the image away from the prompt, which can call attention of the user to the prompt. In some examples, the controller can adjust an illumination level of at least a portion of the backlight panel in response to a sensed ambient light level.
