Abstract
A liquid crystal display module capable of being used in a low temperature environment is provided. The liquid crystal display module includes an LCD panel. The LCD panel includes a GOA circuit. The liquid crystal display module is equipped with a temperature sensor and a heating device. The temperature sensor and the heating device are located beside the GOA circuit. When the temperature sensor detects that the ambient temperature is close to a threshold temperature (e.g., 0° C.), the heating device starts heating. That is, the GOA circuit is not affected by the low temperature. Consequently, the GOA circuit will not fail, and the GOA circuit can be operated normally.
Claims9
A liquid crystal display module, capable of being used in a low temperature environment, comprising:
- a backlight unit comprising a heat sink, a backlight source and a frame, wherein a lateral side of the backlight source is surrounded by the frame, the backlight source is installed in a first opening of the frame, the backlight source is in contact with a surface of the heat sink, and the frame is in contact with an inner sidewall of the heat sink;
- a liquid crystal display (LCD) panel formed on a glass substrate and installed in a second opening of the frame, wherein the LCD panel includes a display region and a non-display region, and a gate on array (GOA) circuit is formed on the non-display region;
- a front cover, wherein a top surface of the front cover is located over the heat sink and the frame, and a lateral side of the front cover is in contact with an outer sidewall of the heat sink, wherein the top surface of the front cover has a hollow portion, and the display region of the LCD panel is exposed to the hollow portion;
- a first temperature sensor installed on the non-display region of the LCD panel and adjacent to the GOA circuit, wherein the first temperature sensor detects an ambient temperature near the GOA circuit during operation of the liquid crystal display module;
- and
- a heating device installed on the non-display region of the LCD panel and adjacent to the GOA circuit, wherein the ambient temperature near the GOA circuit is stably maintained in the low temperature environment if the heating device starts heating.
