Device for temperature detection and device for compensating for temperature of display panel

A device for temperature detection, comprising:

• a first inverter, configured to invert a voltage signal at an input terminal of the first inverter to output an inverted signal;
• a delay assembly, coupled to the first inverter, and configured to delay the inverted signal and to output a delayed inverted signal as an output signal;
• a switching transistor, comprising a control electrode coupled to the delay assembly, a first electrode coupled to a first voltage signal terminal and a second electrode coupled to the input terminal of the first inverter, and configured to apply a first voltage signal from the first voltage signal terminal to the input terminal of the first inverter based on the output signal;
• a first capacitor, comprising a first terminal coupled to the first electrode of the switching transistor and a second terminal coupled to the input terminal of the first inverter;
• and
• a temperature sensing transistor, comprising a control electrode applied with a sub-threshold bias voltage, a first electrode coupled to the input terminal of the first inverter and a second electrode coupled to a second voltage signal terminal, and configured so that a channel current of the temperature sensing transistor is proportional to a temperature at the sub-threshold bias voltage.
