1. A method comprising:
by software on a computing device, dynamically identifying a subregion of a display of the computing device, the display being a liquid crystal display (LCD), wherein the display is backlit by backlighting components, and wherein content of a structured document is associated with the subregion; by the software, determining whether to adjust one or more backlighting components that backlight the subregion, based at least in part on an affinity score, wherein the affinity score represents a measure of affinity between a user associated with the computing device and the content associated with the subregion; and by the software and through a device driver of the computing device, dynamically adjusting the one or more backlighting components when the software determines to adjust the one or more backlighting components, wherein the content associated with the subregion is displayed in the subregion using the adjusted backlighting components.
