摘要：

We have developed a hybrid-type temperature sensor using TFTs. We combined a transistor, capacitor, and ring oscillator and detected the temperature by measuring the oscillation frequency. The large temperature dependences of the off-leakage currents can be utilized, and simultaneously only a digital circuit is required to count the digital pulse. © 2014 Society for Information Display.
