Patent number: 9142157Abstract: An electronic device may contain components such as a processor, video circuitry, camera flash, communications circuitry, and other components that may generate heat during operation. The device may have a display with a backlight unit that contains light-emitting diodes. Control circuitry within the electronic device can apply drive powers to the light-emitting diodes in a way that is sensitive to the operating temperature of the light-emitting diodes. The control circuitry can determine whether the temperature of the light-emitting diodes is elevated by determining which components are active in the device. Activity levels can be ascertained by gathering status information on each component. Temperature sensors may be used to make real time temperature measurements.Type: GrantFiled: January 20, 2011Date of Patent: September 22, 2015Assignee: Apple Inc.Inventors: Joshua G.
