The invention relates to a temperature sensor and a temperature detection method. The temperature sensor comprises: a first substrate and a second substrate which are oppositely arranged, a liquid crystal layer arranged between the first substrate and the second substrate; a first conductive electrode arranged on the side, facing the liquid crystal layer, of the first substrate, wherein the firstconductive electrode comprises a plurality of first electrode blocks distributed in an array mode; a second conductive electrode which is arranged on one side, facing the liquid crystal layer, of thesecond substrate and is opposite to the first conductive electrode to form a liquid crystal capacitor; a third conductive electrode which is arranged on one side, deviating from the liquid crystal layer, of the first substrate, and is connected with a fixed potential to shield an external signal; and a detection assembly which comprises a detection module and a temperature calculation module, wherein the detection module is electrically connected with the first electrode blocks, and the temperature calculation module is electrically connected with the detection module. According to the temperature sensor and the temperature detection method provided by the embodiment of the invention, the temperature sensor can meet the multi-point temperature measurement requirement, and the accuracy of ameasurement result is relatively high.
Description
technical field [0001] The invention relates to the technical field of temperature detection, in particular to a temperature sensor and a temperature detection method. Background technique [0002] The temperature sensor can be used to measure the temperature of a predetermined position of the object to be measured, and is widely used, for example, in the field of display, it can be used to measure the temperature of a display panel. Most of the existing temperature sensors use thermocouples or thermistors combined with thermostat detection methods, and it is difficult to achieve multi-point temperature measurement. Therefore, a new temperature sensor and temperature detection method is urgently needed Contents of the invention [0003] Embodiments of the present invention provide a temperature sensor and a temperature detection method. The temperature sensor can meet the requirement of multi-point temperature measurement, and the accuracy of the measurement result is high...
