Abstract
A device and method for temperature detection, a device and method for compensating for temperature of display panel, and a display device are disclosed. The device for temperature detection includes: a first inverter, inverting a voltage signal at an input terminal thereof to output an inverted signal; a delay assembly, delaying the inverted signal and outputting a delayed inverted signal as an output signal; a switching transistor, applying a first voltage signal to the input terminal of the first inverter from a first voltage signal terminal based on the output signal; a first capacitor, including a first terminal coupled to a first electrode of the switching transistor and a second terminal coupled to the input terminal of the first inverter; and a temperature sensing transistor, configured so that a channel current of the temperature sensing transistor is proportional to a temperature at the sub-threshold bias voltage.
