Abstract

The present disclosure relates to a temperature sensor circuit for measuring temperature change inside a pixel of a high-brightness active matrix micro-light-emitting diode (micro-LED) display, and a display apparatus including the temperature sensor circuit. The temperature sensor circuit according to one embodiment of the present disclosure includes a first thin film transistor, a second thin film transistor interconnected with the first thin film transistor, and a temperature measurement unit for measuring temperature based on an output voltage according to difference in off current between the first thin film transistor and the second thin film transistor.
