TEMPERATURE SENSOR USING ON-GLASS DIODES

摘要

This disclosure provides systems, methods and apparatus for measuring a temperature of a display. In one aspect, a circuit may use one or more stages of diodes or diode-connected transistors providing the functionality of diodes. Each stage may include the functionality of diodes in opposite directions. A direct current (DC) current source or an alternating current (AC) voltage source may be applied to the diodes or diode-connected transistors to measure the temperature of the display.
