TEMPERATURE SENSING DISPLAY ASSEMBLIES |
摘要 |
Systems, methods, and computer-readable media for determining the temperature of a light-generating component of a display assembly using a voltage of the light-generating component are provided. In one embodiment, a method for operating an electronic device, which may include an external surface and a light-emitting diode operative to emit light for illuminating the external surface, may include detecting the forward voltage of the light-emitting diode, calculating the temperature of the light-emitting diode using the detected forward voltage of the light-emitting diode, and altering the performance of the electronic device based on the calculated temperature of the light-emitting diode. Additional embodiments are also provided. |

1. An electronic device comprising:
a display assembly comprising:
an external display surface;a light-emitting diode operative to emit light for illuminating the external display surface; anda component stack extending between the light-emitting diode and a portion of the external display surface, wherein the component stack provides a thermal resistance between the light-emitting diode and the portion of the external display surface; and a sensor management system operative to:
access a correlator that defines a relationship between the forward voltage of the light-emitting diode and the temperature of the light-emitting diode;access the value of the thermal resistance of the component stack between the light-emitting diode and the portion of the external display surface;detect the current forward voltage of the light-emitting diode;determine the current temperature of the light-emitting diode based on the detected current forward voltage of the light-emitting diode and based on the accessed correlator; anddetermine the current temperature of the portion of the external display surface based on the determined current temperature of the light-emitting diode and based on the accessed value of the thermal resistance of the component stack between the light-emitting diode and the portion of the external display surface. |
