1. A display panel, comprising:
a first substrate;
a second substrate;
a liquid crystal layer sandwiched between the first substrate and the second substrate;
a plurality of temperature sensors disposed on the first substrate, wherein each temperature sensor comprises a source, a drain and a gate, and the drain and the gate of each temperature sensor are electrically connected; and the plurality of temperature sensors is configured to detect a temperature by detecting a resistance of the plurality of temperature sensors, and the resistance increases as the temperature decreases;
a plurality of heaters respectively arranged on one side of the first substrate and the second substrate away from the liquid crystal layer;
an electrical signal supply circuit configured to input an electrical signal to the drain of each temperature sensor;
a processor connected to the source of each temperature sensor, and configured to determine whether temperature data acquired by each temperature sensor is below a preset temperature; and
a controller connected to the processor and the plurality of heaters respectively, and configured to control the plurality of heaters to perform heating when the temperature data is below the preset temperature.
