Claim 16:
17. The heating method of the display module of claim 16, wherein the display module further comprises a plurality of temperature sensors, wherein each of the plurality of heating lines is respectively provided with one of the plurality of temperature sensors; wherein the plurality of heating lines is divided into N heating line groups; wherein the gating circuit comprises a plurality of gating signal lines, wherein the plurality of heating lines in a same one of the N heating line groups is electrically connected to different gating units and correspond to a same one of the plurality of gating signal lines; wherein N is a positive integer;
wherein the method further comprises: collecting, by the temperature sensor, a temperature signal of the display panel and sending the temperature signal to the control circuit; and
wherein sending, by the control circuit, the heating control signal to the heating circuit and the gating signal to the gating circuit comprises:
in response to a temperature signal fed back by the temperature sensor corresponding to an i-th heating line group and a preset heating temperature, sending, by the control circuit, the heating control signal to the heating circuit and a gating signal which has a state of the turn-on level to a gating signal line corresponding to the i-th heating line group; wherein i is a positive number and 1≤i≤N.
