Abstract
An electronic device may have a display mounted in a housing. The housing may have a stand that supports the housing on a support surface or may have other shapes. The display may have pixels that display an image. The display may also have a two-dimensional array of light-emitting devices such as light-emitting diodes that supply backlight illumination for the pixels. An array of temperature sensors may be overlapped by the pixels. Control circuitry may maintain historical backlight aging information during operation of the display. The aging information may include information on output brightness levels of the light-emitting diodes and light-emitting diode operating temperatures.
