Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal glass panels, in particular to a heating plate suitable for liquid crystal glass panels. Background Art

[0002] The basic principle of LCD display is to fill liquid crystal material between two pieces of glass, and use voltage to change the arrangement of molecules inside the liquid crystal material to achieve the purpose of light shielding and light transmission to display different pictures. However, the activity of liquid crystal molecules decreases and the reaction speed slows down in low temperature environment, which will cause problems such as ghosting, uneven display, or even failure to display. Therefore, if you want to use the LCD screen stably in a low temperature environment, you need to heat it.

[0003] However, in the prior art, directly attaching a heating film to the LCD screen cannot effectively and evenly heat the screen, and the heating efficiency is low. Therefore, a heating plate suitable for a liquid crystal glass panel is proposed to solve the above problems. Utility Model Content

[0005] To achieve the above object, the utility model provides the following technical solution: a heating plate suitable for a liquid crystal glass panel, comprising a liquid crystal glass panel, an upper polarizer is arranged flatly on the top of the liquid crystal glass panel, a lower polarizer is arranged at the bottom of the liquid crystal glass panel, and a heating component is arranged at the bottom of the lower polarizer;

[0006] The heating assembly includes a heat-conducting film attached to the bottom of the lower polarizer, a heating wire is arranged at the bottom of the heat-conducting film, a fixing plate is attached below the heating wire, the fixing plate is fixed to the bottom of the heat-conducting film, and a buffer is arranged on the surface of the heat-conducting film and the fixing plate.

[0007] Furthermore, the thermally conductive film is a thermally conductive graphite film, and the thermally conductive graphite film wraps the side of the liquid crystal glass panel.

[0008] Furthermore, the heating wires are distributed in a serpentine shape and fit tightly against the bottom of the thermally conductive film.

[0009] Furthermore, a cavity is provided inside the buffer component, the heat-conducting film is located inside the cavity, and the side surface of the heat-conducting film is tightly fitted with the inner wall of the cavity.

[0010] Furthermore, a support block is provided between the fixing plate and the heat-conducting film, and the support block is located in the gap between the heating wires.

[0011] Furthermore, the length and width of the fixing plate are both greater than the distance between the two ends of the heating wire, and the heating wire is laid on the surface of the fixing plate.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The heating plate is suitable for a liquid crystal glass panel. An upper polarizer is arranged on the surface of the liquid crystal glass panel to reduce glare and improve display quality. When the liquid crystal glass panel is in use, the heating wire is energized to generate heat by using resistance. Since the heating wire is attached to the surface of the heat-conducting film, heat can be transferred to the heat-conducting film. Due to the presence of the heat-conducting film, the temperature can be evenly conducted. The heat-conducting film is attached to the lower polarizer, so that heat is transferred to the liquid crystal glass panel through the lower polarizer to prevent the liquid crystal molecules from being inactive due to too low temperature. The fixing sheet is attached to the heat-conducting film and the heating wire is wrapped between the fixing sheet and the heat-conducting film. Therefore, when the heating wire needs to be replaced and maintained, the fixing sheet can be directly torn off to replace the heating wire, thereby achieving easy maintenance.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The heating component 4 disposed below the lower polarizer 3 can be heated, thereby transferring heat to the liquid crystal glass panel 1 through the lower polarizer 3, thereby preventing the liquid crystal molecules in the liquid crystal glass panel 1 from having reduced activity and slowing down the reaction speed in a low temperature environment.

[0022] By energizing the heating wire 402, heat is generated by resistance. Since the heating wire 402 is bonded to the surface of the thermally conductive film 401, heat can be transferred to the thermally conductive film 401. Due to the presence of the thermally conductive film 401, the temperature can be evenly conducted, and the thermally conductive film 401 is bonded to the lower polarizer 3, so that heat is transferred to the liquid crystal glass panel 1 through the lower polarizer 3 to prevent the liquid crystal molecules from being inactive due to low temperature. The fixing sheet 403 is bonded and fixed to the thermally conductive film 401, and the heating wire 402 is wrapped between the fixing sheet 403 and the thermally conductive film 401.

[0024] The upper polarizer 2 is arranged on the surface of the liquid crystal glass panel 1 to reduce glare and improve display quality. When the liquid crystal glass panel 1 is in use, the heating wire 402 is energized to generate heat by resistance. Since the heating wire 402 is attached to the surface of the thermal conductive film 401, the heat can be transferred to the thermal conductive film 401. Due to the presence of the thermal conductive film 401, the temperature can be evenly conducted. The thermal conductive film 401 is attached to the lower polarizer 3, so that the heat is transferred to the liquid crystal glass panel 1 through the lower polarizer 3 to prevent the liquid crystal molecules from being inactive due to low temperature. The fixing sheet 403 is attached to the thermal conductive film 401 and the heating wire 402 is wrapped between the fixing sheet 403 and the thermal conductive film 401. Therefore, when the heating wire 402 needs to be replaced and maintained, the fixing sheet 403 can be directly torn off to replace the heating wire 402, thereby facilitating maintenance.
