Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display, in particular to the technical field of a liquid crystal display module with a heating function. Background Art

[0002] In order to prevent water vapor from entering the display screen due to poor sealing of the customer host, resulting in blurred display images and affecting user experience, a heater is added to the ordinary TFT structure in the field of liquid crystal display to continuously heat the TFT and reduce the deposition of water vapor. The traditional heating structure is to make ITO wiring on the glass, and then weld the heater's FPC to the FPC of the main screen TFT. However, once the welding is completed, if there is a connection problem, it is necessary to re-weld or process the welding point, which will make repair and replacement relatively difficult. In addition, the FPC welding connection makes the connection between the heater and the main screen TFT fixed, which is not conducive to replacing or adjusting the position of the heater when needed, and the flexibility is limited.

[0021] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0022] It should be noted that when one part is considered to be "connected" to another part, it can be directly connected to the other part or connected by a central component. The terms "one end", "the other end", etc. used in this article indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the utility model.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] See also Figure 1 In one embodiment provided by the utility model, a liquid crystal display module with a heating function includes a heating component 1, a double-sided adhesive 2, a liquid crystal display panel 3, and a main screen FPC 4. The heating component 1 includes a thin film heater 11, an electric wire 12, and a socket 13. One end of the electric wire 12 is connected to the thin film heater 11, and the other end is connected to the socket 13. The thin film heater 12 is attached to the liquid crystal display panel 3 through the double-sided adhesive 2, and the main screen FPC is bound to the liquid crystal display panel. In this way, the heater 11 is connected and disassembled through a simple plug-in operation, which is simple and convenient. The way of gluing the double-sided adhesive 2 and connecting the socket 13 makes it highly flexible when the heater 11 needs to be adjusted or replaced.

[0025] See also Figure 2-5 In this embodiment, the thin film heater 11 is an ITO thin film. The ITO thin film heater can ensure visual clarity of the heating area, high safety, and fast heating and cooling speeds. It can quickly reach the set temperature and quickly cool down when needed to achieve uniform heating and ensure consistent temperature distribution in the entire heating area.

[0026] In this embodiment, insulating material is provided around the heater 11, and silicone rubber, glass fiber, or ceramic fiber is recommended to ensure the electrical safety of the heater and prevent heat or current from causing adverse effects on the surrounding environment.

[0027] In this embodiment, the thin film heater 11 is connected by a curved line, and the endpoints of the curved line in the same direction are connected to form a connecting line. A solder position 111 is provided at one end of the connecting line. The end of the electrical conductor 12 connected to the solder position has exposed lead-free solder on the solder position 111, thereby achieving heating at both ends, which is beneficial to providing a uniform heating effect and avoiding the formation of hot spots or cold spots. In addition, this design method facilitates the manufacture and assembly of the heater.

[0028] It is understandable that in different implementations, according to different product heating requirements, a linear or grid-type heater 11 can be used, and the solder positions can be distributed as needed, mainly to meet the purpose of uniform heating.

[0029] In this embodiment, the electric wire 12 is connected to the socket 13 through a plug, which is convenient to use and easy to replace. The connection between the electric wire and the plug of the socket 13 is reinforced with a heat shrink tube or insulating tape to prevent the electric wire 12 from loosening or breaking.

[0030] It should be noted that, in another implementation of this embodiment, the electrical conductor 12 may also be connected to the socket 13 via a terminal box.

[0031] In another implementation of this embodiment, a temperature sensing IC can be connected to the electrical conductor 12. The temperature sensing IC is provided with a sensing element and a switching microcontroller or a switching element. The temperature detected by the sensing element forms a relevant signal. The temperature sensing IC controls the switching microcontroller or the switching element according to the transmitted signal to start or shut down the heating circuit, thereby achieving precise control, ensuring the stable operation and safety of the heater 11 and even the entire liquid crystal display component, and improving its corresponding lifespan.

[0032] In summary, the heater 1 on the liquid crystal display panel 3 adopts a socket connection method, which can make the connection between the heater 1 and the main screen TFT detachable, convenient for maintenance and replacement when necessary, and the socket 13 connection allows the position of the heater 1 to be easily adjusted or the heater 1 of different specifications to be replaced when necessary, which is highly flexible.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
