Abstract
A thin-film semiconductor device includes a temperature sensor formed of a thin-film semiconductor and sensing a temperature as current, and a current-voltage converter formed of a thin-film semiconductor and having temperature dependence in which its current-voltage characteristic is different from that of the temperature sensor. A temperature sensed by the temperature sensor is converted to a voltage by the current-voltage converter.
Claims6
A thin-film semiconductor device comprising:
- a temperature sensor formed of a first thin-film semiconductor constructed and arranged to find a temperature by sensing a current;
- a current-voltage converter formed of a second thin-film semiconductor and having a temperature dependence in which its current-voltage characteristic is different from that of said temperature sensor;
- and
- an amplifier amplifying said voltage converted by said current-voltage converter;
- wherein a temperature found by said temperature sensor is converted to a voltage by said current-voltage converter.
