Description

Technical Field

[0001] This utility model relates to the technical field of display accessories, and in particular to an OSD button structure for a display. Background Technology

[0002] OSD (On-Screen Display) is an advanced feature for monitors, offering menu-driven adjustment options. Pressing the menu button brings up a rectangular menu on the screen containing various settings and parameters. Users can adjust settings such as color, mode, brightness, and contrast to achieve optimal performance.

[0003] The current OSD button structure of monitors is generally installed internally. Specifically, the tactile switches on the OSD button panel are exposed through structural openings to enable press-to-use functionality. OSD button adjustment instructions are processed onto the monitor's surface using methods such as silkscreening or etching. This type of OSD button structure makes it difficult to effectively meet requirements for moisture resistance, dust resistance, anti-static properties, and electromagnetic interference protection. Furthermore, the internal installation method is inconvenient for OSD button maintenance and installation. Because the OSD button adjustment instructions are processed onto the monitor's surface using silkscreening or etching, it cannot meet the customized needs of different customers, resulting in high manufacturing and replacement costs. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0033] Reference Figures 1-5 An embodiment of this utility model provides an OSD button structure for a display, including a main body unit 100, a sealing unit 200, and a mounting unit 300.

[0034] The main unit 100 includes an OSD keypad 101 and a key membrane 102. The OSD keypad 101 is installed in a pre-set groove in the display structure and is used to receive press signals and trigger corresponding OSD menu adjustment functions. The OSD keypad 101 further includes a tactile switch 1011, a circuit board 1012, and a switch holder 1013. The circuit board 1012 serves as a support structure for the OSD keypad 101 and is responsible for connecting various components and transmitting electrical signals. The tactile switch 1011 is the core component on the OSD keypad 101, used to receive user press signals. The switch base 1013 is a hollow structure, arranged on the circuit board 1012 at the position corresponding to the tactile switch 1011. The front side of the switch base 1013 has a telescopic groove for the tactile switch 1011 to be pressed and extended. The switch base 1013 contains a conductive spring 1014, which has an arc-shaped cross-section, with its convex end connected to the tail end of the tactile switch 1011. When the tactile switch 1011 is pressed, the conductive spring 1014 deforms, allowing current to flow smoothly through the conductive spring 1014 and contact the corresponding contact point on the circuit board 1012, realizing the tactile switch press signal. The touch switch 1011 controls the circuit; the circuit board 1012 has two sets of upper and lower limit seats 1015 arranged at the position corresponding to the switch base 1013, and the limit seats 1015 are fixedly connected to the circuit board 1012; the switch base 1013 has a limit groove adapted to its structure at the position corresponding to the limit seat 1015, and the switch base 1013 is fitted onto the limit seat 1015 through the limit groove to prevent displacement and ensure the stability of the structure; the button membrane 102 covers the OSD button board 101, and the OSD button adjustment function is printed on it for easy user identification and operation; the button membrane 102 is preferably made of PVC / PET material, which is convenient for customization and replacement according to customer needs.

[0035] The sealing unit 200 includes an epoxy board pad 201, which is disposed between the OSD keypad 101 and the display structure. The epoxy board pad 201 is made of epoxy resin and fiberglass cloth through lamination and curing, and has high insulation performance, good dielectric properties and corrosion resistance. The epoxy board pad 201 has an assembly groove that is used in conjunction with the switch base 1013, the limit base 1015 and the tactile switch 1011 to provide support and isolation functions, and achieve the effects of moisture-proof, dust-proof, anti-static and anti-electromagnetic interference.

[0036] The mounting unit 300 includes screws 301 and double-sided adhesive. Screws 301 are positioned in a pre-set groove within the display structure to mount the OSD button panel 101, button membrane 102, and epoxy board spacer 201 as a single module, enabling modular installation and maintenance. Double-sided adhesive is applied to the side of the button membrane 102 closest to the OSD button panel 101, allowing the button membrane 102 to adhere to the OSD button panel 101 and epoxy board spacer 201, further enhancing structural stability and ease of installation.

[0037] In this embodiment, the specific implementation steps of the OSD button structure of the display are as follows:

[0038] The OSD keypad 101 is installed in a pre-set groove in the display structure, wherein the tactile switch 1011 is slidably mounted on the circuit board 1012; the epoxy board pad 201 is placed between the OSD keypad 101 and the display structure, ensuring that it cooperates with the switch holder 1013, the limit holder 1015 and the tactile switch 1011; the OSD keypad 101, the key film 102 and the epoxy board pad 201 are installed as a whole module in the pre-set groove of the display structure using screws 301, thus completing the modular installation.

[0039] In actual use: To activate the OSD menu: Press any OSD button on the monitor (e.g., ...). Figure 1 As shown, the tactile switch 1011 receives the press signal and triggers the corresponding OSD menu adjustment function (identified by the marking on the button membrane 102).

[0040] Menu navigation and adjustment: Use the OSD buttons to navigate and adjust parameters according to the OSD menu displayed on the monitor screen.

[0041] If the button membrane 102 wears out due to prolonged use or requires a new pattern, gently peel off the double-sided adhesive, remove the old membrane, and paste the new membrane using the same method.

[0042] If you need to repair or replace the internal components of the OSD button structure, first remove screw 301, take the whole module out of the preset groove, then disassemble and replace it step by step, and finally reassemble and install it back on the monitor.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
