Description

Technical Field

[0001] This utility model relates to a display device and belongs to the field of display technology. Background Technology

[0002] Existing smart devices include personal computers, laptops, tablets, and mobile terminals, where a secondary screen serves as a second display unit, providing an independent display area for multitasking or entertainment. In related technologies, the secondary screen structure typically consists of a support step formed by a recessed inner side of a frame, supporting the screen assembly and secured with adhesive. This structure suffers from drawbacks such as difficult assembly and inconvenient maintenance. Utility Model Content

[0003] This utility model provides a display device, which aims to solve at least one of the technical problems existing in the prior art.

[0004] Therefore, this utility model proposes a display device whose structure is easy to assemble and disassemble, and also easy to maintain.

[0005] The technical solution of this utility model relates to a display device, comprising:

[0006] Main frame, display screen, display screen driver board;

[0007] The main frame is provided with a transverse baffle along the circumference inside, which divides the internal space of the main frame into an upper space and a lower space.

[0008] The display screen is disposed in the lower space of the main frame, and the front side of the display screen abuts against the horizontal baffle.

[0009] The display screen driver board is disposed in the lower space of the main frame on the rear side of the display screen;

[0010] The display device also includes an LED light panel, which is disposed in the lower space of the main frame behind the display screen. In addition to LEDs, the LED light panel is also provided with a column for abutting against the back of the display screen.

[0011] Furthermore, to simplify installation, in one possible implementation, the LED panel is fixed to the lower space of the main frame by an interference fit. Obviously, those skilled in the art would also conceive of using adhesives to replace or assist the interference fit.

[0012] As an alternative to the above embodiment, the main frame may include a convex middle step and a concave lower step, and the LED light panel is fastened to the lower step of the main frame by a matching lower frame to fix the LED light panel in the lower space of the main frame.

[0013] Similarly, it is conceivable that, in addition to fastening the lower frame (e.g., by using an interference fit) to the lower step of the main frame, adhesive can also be used to assist in fixation.

[0014] As a further improvement to the display device of this utility model, a protective panel is also included, which is disposed in the upper space of the main frame and abuts against the horizontal baffle; optionally, the protective panel is a touch panel.

[0015] Furthermore, to simplify installation, in one possible implementation, the protective panel is fixed to the upper space of the main frame by an interference fit. Alternatively, the protective panel can also be fixed to the upper space of the main frame by adhesive. For example, adhesive can be applied to a transverse baffle to bond the protective panel.

[0016] As an alternative to the above embodiment, the main frame includes a convex middle step and a concave upper step, and the protective panel is fastened to the upper step of the main frame by a matching upper frame, thereby fixing the protective panel in the upper space of the main frame.

[0017] Similarly, it is conceivable that, in addition to fastening the upper frame (e.g., by using an interference fit) to the upper step of the main frame, adhesive can also be used to assist in fixation.

[0018] It should be noted that the installation methods such as interference fit and snap-fit ​​involved in this application can also be supplemented by threaded connection, adhesive connection, etc., or directly use threaded connection, adhesive connection, etc. Any technical solution that achieves a similar connection effect in a way that can be conceived by a person skilled in the art should be considered as a simple replacement of the technical solution of this application, and thus should be considered to fall within the protection scope of this application.

[0019] Furthermore, a wiring hole is provided on one side of the main frame for connecting an external power source, such as connecting to a computer's USB port via a USB cable, or connecting to a portable power bank.

[0020] In one possible implementation, the display driver board is fixed to the LED light board, for example, by screws. That is, the display driver board and the LED light board are separate designs. Alternatively, in another possible implementation, the display driver board is directly integrated with the LED light board into the same circuit board, or the display driver board can also be integrated with the display screen into a display assembly. It should be noted that since the LED light board has a simple structure, for example, it can be a two-layer circuit board in production, while the display driver board has a complex structure, for example, it requires a four-layer circuit board in production. Therefore, integrating the two may significantly increase production and maintenance costs. However, regardless of whether a separate or integrated design is adopted, it should be considered to fall within the protection scope of this application.

[0021] Furthermore, in one embodiment of this utility model, the display driver board is electrically connected to the LED light board. As can be seen from the above description, this electrical connection can be through traces in an integrated circuit or through wires. The display driver board and the LED light board are connected to an external power source, such as a computer's USB interface or a portable power bank, through a single connecting wire.

[0022] In use, one feasible method is to fix the display device involved in this application to the fan inside the computer case. Based on this, the column is a hollow column with internal threads, which extends through to the back side of the LED light panel. When fixing, the hollow column is connected by double-headed bolts and then fixed in a suitable position inside the case.

[0023] The beneficial effects of this utility model are as follows:

[0024] The display device provided in this embodiment of the utility model avoids fixing the display screen with a large amount of adhesive by setting the display screen in the lower space of the main frame, which facilitates disassembly during assembly and maintenance. At the same time, the display screen driver board and LED light board can be designed separately, reducing production and maintenance costs. Attached Figure Description

The upper frame 200 covers the side of the main frame 100, and the lower frame 300 covers the side of the main frame 100. Screw positions 131 are provided at the four corners of the lower step portion 130 and the lower frame 300. Screw positions 131 are provided at the center of the long side of the lower step portion 130 and the lower frame 300. The display screen 400 is disposed in the lower space of the main frame 100 and is fixed to the main frame 100 by screws (not shown in the figure) passing through the screw positions 131.

[0043] See Figure 2 In another embodiment of this utility model, a display device is provided, which includes a main frame 100, a display screen 400, a display screen driver board 700, and an LED light board 800, which is different from... Figure 1 In the illustrated embodiment, the display screen 400 is merely a display panel. This embodiment also provides a display screen driver board 700 for driving the display screen 400 to display digital content. In addition, to provide better visual effects, this embodiment also provides an LED light board 800, which is provided with a plurality of LEDs. The driving circuit on the LED light board 800 enables each LED to present the same or different colors, color temperatures and / or brightness, providing a colorful visual effect through the main frame 100.

[0044] In this embodiment, a transverse baffle 111 is provided circumferentially inside the main frame 100, dividing the internal space of the main frame 100 into an upper space and a lower space. The display screen 400 is disposed in the lower space of the main frame 100, with its front abutting against the transverse baffle 111. To protect the display screen 400, a protective panel 500 is also provided in this embodiment. The protective panel 500 is disposed in the upper space of the main frame 100, with its back abutting against the transverse baffle 111. It should be noted that, in addition to using a common panel to provide only protection, the protective panel 500 can also be configured as a touch panel to provide touch functionality for the display screen 400.

[0053] See Figure 1 In some embodiments, the upper frame 200, the main frame 100, and the lower frame 300 are rectangles, and the four corners of the upper frame 200, the main frame 100, and the lower frame 300 are rounded.

[0054] See Figure 1 In some embodiments, the thickness of the middle step portion 120 is less than the thickness of the upper step portion 110, and the thickness of the middle step portion 120 is less than the thickness of the lower step portion 130.

[0055] In some specific embodiments, the spacing between each LED on the LED light board 800 in the main frame and / or the spacing between the LED light board 800 and the display screen 400 are set to make the entire frame evenly illuminated, which helps to avoid the generation of light spots.

[0056] In one possible implementation, the LED light board 800, the display driver board 700, and the display screen 400 are arranged from bottom to top to match the width of the inner side of the frame.
