Display having integrated thermal sensors

摘要

Thermal sensors are disposed with OLEDs across a display of an electronic device to measure temperatures across the display surface. Thermal sensors may be used to create a temperature map across the display surface due to both the ambient environment and the internal environment of the electronic device. The thermal sensors may be disposed in the OLED layer, on a separate layer, or both. Thermal sensors may be disposed in a substantially 1:1 ratio with OLEDs or with zones of OLEDs. Both the temperature history and usage history for OLEDs may be recorded and processed to determine the age of each OLED. Controllers may adjust the driving strength of OLEDs or adjust the operation of components within the electronic device to compensate for aging or temperature based on the temperature map and age determination. Controllers may move static images from one part of the display to another less-aged part.

主权项

1. A display, comprising:
a plurality of organic light emitting diodes (OLEDs) disposed across the display, wherein each OLED of the plurality of OLED emits light in response to control signals; a plurality of thermal sensors disposed across the display, the plurality of thermal sensors being configured to measure a plurality of temperatures across the display and generate signals relating to the measured plurality of temperatures; and a controller configured to move a location of an image on the display from a first location to a second location based at least in part on the signals relating to the measured plurality of temperatures, and a first average temperature of the first location is greater than a second average temperature of the second location due substantially to heat from electronic components proximate the display.
