Zusammenfassung:The invention discloses a pixel circuit with a temperature measurement function. The pixel circuit comprises a photosensitive diode, a temperature-sensitive diode, an alternative switch, a signal sampling switch, an integrating capacitor, a capacitor reset switch, a source follower and the like. Wherein the cathode of the photosensitive diode is connected with one input end of the either-or switch, and the anode is grounded; the positive electrode of the temperature-sensitive diode is connected with one input end of the either-or switch, and the negative electrode is grounded; the output end of the either-or switch is connected with one end of the signal sampling switch, the other end of the signal sampling switch, the capacitor reset switch and the positive plate of the integrating capacitor are connected with the input end of the source follower, the negative plate of the integrating capacitor is grounded, and the other end of the capacitor reset switch is connected with reset voltage; and the output end of
