Claim 5:
6. A temperature control method for a liquid crystal display device, the liquid crystal display device having a display area and a non-display area, and the liquid crystal display device comprising a liquid crystal display module; a control module connected to the liquid crystal display module and comprising a temperature detection unit, a temperature adjustment unit and a control unit; an array substrate connected to the control module; a color filter substrate disposed opposite to the array substrate; a liquid crystal layer disposed between the array substrate and the color filter substrate; a first index margin erasing layer disposed between the array substrate and a heat generating layer; and a second index margin erasing layer disposed on a side surface of the heat generating layer away from the color filter substrate; and the first index margin erasing layer and the second index margin erasing layer being configured to make the heat generating layer more transparent such that a reflectivity of the entire display area is completely consistent with a reflectivity of the heat generating layer;
wherein the temperature control method for the liquid crystal display device comprises following steps:
S1, detecting a temperature of a part of the liquid crystal display module located in the display area, the temperature of the part of the liquid crystal display module located in the display area being a first temperature; and detecting a temperature of a part of the liquid crystal display module located in the non-display area, the temperature of the part of the liquid crystal display module located in the non-display area being a second temperature;
S2, determining whether the first temperature and the second temperature are lower than a target temperature threshold, respectively;
S3, heating the part of the liquid crystal display module located in the display area in a case that the first temperature is lower than the target temperature threshold; and heating the part of the liquid crystal display module located in the non-display area in a case that the second temperature is lower than the target temperature threshold; and
S4, stopping heating the part of the liquid crystal display module located in the display area when the first temperature reaches the target temperature threshold; stopping heating the part of the liquid crystal display module located in the non-display area in a case that the second temperature reaches the target temperature threshold; and simultaneously waiting to enter a next sampling period, that is, returning to the step S1.
