Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal screens, in particular to a new type of large-size liquid crystal display module. Background Technique

[0002] For a conventional liquid crystal display module, the liquid crystal screen is fixed in a frame, and the frame is rigidly connected to the rest of the parts by screws. When the liquid crystal display module is used in an airborne environment, it will be affected by vibration factors. During vibration, the load is transmitted to the liquid crystal screen through the outer frame, causing it to deform, and then vibration white spots are generated, which is particularly obvious when displaying a black field. Such display anomalies will affect the quality of the displayed image, and for large-size liquid crystal display modules, vibration white spot display is more likely to occur. Therefore, a new type of large-size liquid crystal display module is proposed. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problems mentioned in the above background technique, and to propose a new type of large-size liquid crystal display module.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A new type of large-size liquid crystal display module, including a panel, a mounting frame, a backlight cover, a backlight assembly, a screen frame and a liquid crystal screen. The mounting frame is installed on the inner wall of the panel, the backlight cover is installed on the mounting frame, the backlight assembly is arranged on the backlight cover, the lower end of the screen frame is connected to the upper end surface of the backlight cover, and the liquid crystal screen is installed in the screen frame.

[0006] Preferably, a circle of first gaskets is installed on the top of the panel, the first gaskets are in contact with the liquid crystal screen, a second gasket is arranged between the top of the mounting frame and the backlight cover, and a circle of third gaskets is installed on the inner wall of the panel and is in contact with the backlight cover.

[0007] Preferably, the mounting frame and the panel are connected by screws, and the backlight cover and the screen frame are connected by screws.

[0008] Preferably, the first gasket, the second gasket and the third gasket are all made of silicone rubber material.

[0009] In the utility model, compared with the prior art, the advantages are as follows:

[0010] The utility model is provided with the first gasket, the second gasket and the third gasket to limit the screen frame assembly from three directions. Since the screen frame assembly and external parts are separated by silicone rubber gaskets, the connection stiffness between parts is reduced, and the vibration damping effect can be achieved while strengthening, effectively improving the white spot problem of the large-size liquid crystal module in a vibration environment and improving the display quality.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Refer to Figure 1-6 As shown, a new type of large-size liquid crystal display module includes a panel 1, a mounting frame 2, a backlight cover plate 3, a backlight assembly 4, a screen frame 5, and a liquid crystal screen 6. The mounting frame 2 is installed on the inner wall of the panel 1, the backlight cover plate 3 is installed on the mounting frame 2, the backlight assembly 4 is disposed on the backlight cover plate 3, the lower end of the screen frame 5 is connected to the upper end surface of the backlight cover plate 3, and the liquid crystal screen 6 is installed in the screen frame 5.

[0020] In this embodiment, a circle of first gaskets 7 is installed on the top of the panel 1, the first gaskets 7 abut against the liquid crystal screen 6, a second gasket 8 is provided between the top of the mounting frame 2 and the backlight cover plate 3, and a circle of third gaskets 9 is installed on the inner wall of the panel 1 to abut against the backlight cover plate 3.

[0021] In this embodiment, the mounting frame 2 and the panel 1 are connected by screws, and the backlight cover plate 3 and the screen frame 5 are connected by screws.

[0022] In this embodiment, the first gasket 7, the second gasket 8, and the third gasket 9 are all made of silicone rubber material, and silicone rubber has good heat resistance and low temperature resistance.

[0023] Working process and its principle:

[0024] In use, the liquid crystal screen 6 is reinforced in the screen frame 5 with the first gasket 7, and the backlight assembly 4 is reinforced in the backlight cover 3. The screen frame 5 and the backlight cover 3 are rigidly connected with screws to form a frame assembly. A rubber gasket with a certain thickness is attached to the inner side of the panel 1, and the frame assembly is placed in the panel 1 and positioned by the third gasket 9 attached inside the panel 1. A second gasket 8 with a certain thickness is attached to the mounting frame 2, and the mounting frame 2 is fixed to the panel 1 with screws. At the same time, the second gasket 8 attached to the mounting frame 2 presses on the frame assembly to ensure that the frame assembly is limited in all three directions. Since the frame assembly and the external parts are separated by rubber gaskets, the connection stiffness between the parts is reduced, and the vibration damping effect can be achieved while strengthening.

[0025] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
