Abstract
According to the embodiments of the present disclosure, there is provided a sensor for detecting a temperature. The sensor comprises a switch circuit; a charge/discharge circuit connected to the switch circuit, and configured to be charged and discharged under control of the switch circuit; a sensing circuit connected to the charge/discharge circuit, and configured to cause a charge/discharge period of the charge/discharge circuit to change with a temperature of the sensing circuit; and an oscillation circuit connected to the switch circuit and the charge/discharge circuit, and configured to generate, under action of the charge/discharge circuit, an oscillation signal for controlling the switch circuit, wherein an oscillation frequency of the oscillation signal is dependent on the charge/discharge period and thus indicates the temperature of the sensing circuit. In addition, the embodiments of the present disclosure further provide an array substrate and display comprising the sensor, and a corresponding voltage adjustment method.
