Description

Technical Field

[0001] This invention relates to the field of dual-screen display technology, specifically to a dual-screen display device. Background Technology

[0002] Multi-screen display devices (such as portable multi-screen terminals) allow users to monitor or operate multiple applications simultaneously, becoming an important tool for improving multitasking efficiency. In these devices, adjusting screen display parameters (such as brightness, contrast, and color temperature) generally follows the traditional single-screen interaction mode, where physical buttons are placed on the bezels of each monitor, and settings are completed in conjunction with an on-screen menu adjustment system (OSD). When a user presses a specific button, an OSD menu pops up overlaid on a local area of ​​the corresponding screen, allowing the user to continue navigating the menu and adjusting parameters using the buttons. In this mode, physical operation and visual feedback are strictly bound to the same screen.

[0003] However, directly applying the discrete interaction architecture used for single screens to multi-screen devices leads to a series of convenience drawbacks. Specifically: There is a one-to-one physical lock relationship between physical buttons and OSD menus. If users want to adjust the display status of different screens separately, they must touch the independent button groups of each screen one by one. It is difficult to form a centralized control node that can globally schedule multiple screens, thus disrupting the continuous operation flow of multi-screen collaboration. When multiple screens need to be linked to achieve a unified overall visual effect, users can only rely on memory to repeatedly input similar parameter combinations in different independent OSD menus. The setup process is complicated and time-consuming, and it is extremely difficult to ensure a high degree of consistency of parameters between multiple screens, resulting in low interaction efficiency. When the OSD menu is activated, it temporarily covers the current effective business content on the screen. Even if the obscuring time is short, it is enough to interrupt the user's continuous capture of key information. In scenarios that rely on full-screen monitoring or multi-window reference, it actually occupies valuable resources of the main display area and reduces the overall effective availability of the screen.

[0004] It is evident that the existing interaction solution that combines physical buttons with an independent OSD has prominent problems in multi-screen environments, such as barriers to cross-screen operation, inability to coordinate settings, and obscuring of the main screen content. Summary of the Invention

[0005] The purpose of this invention is to provide a dual-screen display device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dual-screen display device, comprising a back panel and two display screens, wherein the two display screens are symmetrically arranged on both sides of the back panel, and the display screens are hinged to the back panel via a second hinge; A bracket is provided on the back plate, and the bracket is used to support the back plate. The motherboard is installed inside the bracket, and the motherboard is electrically connected to the display screen; An interactive screen module is embedded in one side of the back panel. A button is provided on the back panel. The button is used to control the interactive screen module to perform preset operations. The interactive screen module is electrically connected to the motherboard. The motherboard is powered on and connected to an interface located on the side of the bracket.

[0007] Preferably, the back plate is provided with a storage section, and the storage section is provided with a first hinge inside; The bracket can rotate about the axis of the first hinge, allowing it to switch between a retracted state (where it is housed within the storage section) and a support state (where it supports the back plate).

[0008] Preferably, the storage portion is a through hole, and the storage portion penetrates the back plate along the thickness direction.

[0009] Preferably, the interface is disposed on the side edge surface of the bracket; When the bracket is in the retracted state, the interface faces the inner wall of the retracted part.

[0010] Preferably, an anti-slip pad is fixedly provided on the side edge of the bracket away from the first hinge.

[0011] Preferably, a limiting frame is fixedly provided inside the storage part, and the limiting frame is used to limit the position of the bracket when it is in the storage state.

[0012] Preferably, both sides of the back panel are fixed with protruding brackets, the protruding brackets protrude from one of the surfaces of the back panel, and the height of the protruding portion is greater than or equal to the thickness of the display screen.

[0013] Preferably, the back plate has a groove on its side, and the button is disposed in the groove.

[0014] Preferably, the back plate has a handle hole.

[0015] Preferably, the bracket includes a first outer shell and a second outer shell that are fixedly connected, and a wire groove is formed between the first outer shell and the second outer shell; The motherboard and the display screen are electrically connected via a ribbon cable, which is located inside a cable tray.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention breaks away from the traditional discrete layout where buttons and OSD menus on each display screen are physically locked and cannot be centrally managed. It allows users to seamlessly control both screens from a single location, eliminating the need to move between screens or switch between them. This truly achieves centralized management and smooth interaction across multiple screens, eliminating barriers to cross-screen operation. Furthermore, leveraging the centralized control capabilities of the motherboard and the integrated control menu displayed on the interactive screen module, the brightness, color temperature, and other parameters of both screens can be simultaneously calibrated with a single button press. This simplifies the cumbersome "single-screen loop setting" of traditional solutions into "multi-screen parallel response," significantly reducing the frequency and time loss of collaborative operations, ensuring a high degree of visual uniformity, and realizing a synchronized setting mechanism with underlying linkage. Furthermore, this application separates the interactive feedback interface from the two displays and migrates it independently to an interactive screen module located on the back panel. All status information during parameter adjustment is centrally displayed on this additional screen, ensuring that the two displays are completely free from visual interference and obstruction from the menu layer when processing business content in full screen. This guarantees the continuity and integrity of the information displayed on the screens and achieves non-intrusive, non-obstructive adjustment. Moreover, by integrating the buttons and interactive screen module onto the back panel, this application provides an intuitive logical operation entry point while maintaining the simplicity and orderliness of the device's appearance, without altering the existing display body thickness and front-end integration constraints. It simultaneously satisfies the requirements of good tactile feedback and compact construction within a limited space.

[0017] The back panel of this invention has raised brackets fixed on both sides, each protruding from one surface of the back panel, with the height of the protrusion greater than or equal to the thickness of the display screen. During actual installation, the raised brackets are fixedly connected to the back panel, and the display screen is hinged to the raised brackets via a second hinge. The advantage of this installation method is that when folding and storing the two displays, there is no need to follow a fixed order. For example, in this technical solution, the left display screen can be folded and stored first, followed by the right display screen, resulting in the structure shown in the figure; or the right display screen can be folded and stored first, followed by the left display screen, also resulting in the structure shown in the figure. This improves the convenience of storage and prevents damage to the display screen due to an incorrect folding order, thus enhancing safety. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-9 The present invention provides a technical solution: A dual-screen display device includes a back panel 1 and two displays 2. The back panel 1 can be made of materials such as carbon fiber, aluminum alloy, and magnesium alloy. In this embodiment, the back panel 1 is made of engineering plastic, which has advantages in cost, weight, and processability. Furthermore, in this embodiment, the back panel 1 is generally rectangular, and its surface area is substantially the same as that of the displays 2.

[0022] Display screen 2 is used to display image information. Those skilled in the art will understand that the display panel of display screen 2 can be any of a liquid crystal display panel (LCD), an organic light-emitting diode display panel (OLED), or an electronic paper display panel, and its specific pixel driving and backlighting principles are existing mature technologies, which will not be described in detail here.

[0023] Two displays 2 are symmetrically arranged on both sides of the back plate 1. The displays 2 are hinged to the back plate 1 via the second hinge 11. The second hinge 11 can be a damping hinge. The core working principle of the damping hinge is to use the frictional resistance inside the mechanism to generate a torque opposite to the direction of rotation, so as to resist the natural drooping of the screen due to gravity and other forces, thereby achieving stable suspension at any angle.

[0024] A bracket 3 is provided on the back plate 1 to support the back plate 1, so that the back plate 1 can be tilted at a predetermined angle under the support of the bracket 3. The bracket 3 can be made of materials such as carbon fiber, aluminum alloy and magnesium alloy. In this embodiment, the bracket 3 is made of engineering plastic.

[0025] The bracket 3 houses a motherboard 4, which is electrically connected to the display screen 2. In this technical solution, one motherboard 4 is provided, and the two display screens 2 are controlled through this single motherboard 4. The motherboard 4 integrates a central processing unit (CPU), a graphics processor (GPU), display interface circuitry, and a power management module, among other main functional units. Its basic working principle is as follows: the GPU renders independent image frames corresponding to each display screen in the video memory according to system instructions. Then, it sends multiple video data streams to the corresponding display interface controllers. Each interface controller independently outputs timing signals and pixel data, which are then sent to the corresponding display screen's driver board via flexible cables or other transmission media to drive the display screen to display the corresponding image, thus achieving multi-screen collaborative operation. The power management module, controlled by the CPU, provides different voltage rails to each display screen and can independently control the on / off state of each power supply to support independent standby or wake-up functions for the screens. These modules work together to logically and electrically integrate multiple display screens into a controlled whole. This motherboard architecture and operating method are well-known to those skilled in the art and can be easily implemented.

[0026] In this embodiment, the bracket 3 includes a first outer shell 301 and a second outer shell 302 that are fixedly connected. The fixed connection between the first outer shell 301 and the second outer shell 302 can be a bolt connection. A wire groove 303 is formed between the first outer shell 301 and the second outer shell 302. The motherboard 4 and the display screen 2 are electrically connected via a ribbon cable 5, which is disposed inside the wire groove 303. The entire ribbon cable 5 is hidden, resulting in a good overall aesthetic appearance.

[0027] An interactive screen module 8 is embedded in one side of the back panel 1. Buttons 9 are provided on the back panel 1, used to control the interactive screen module 8 to perform preset operations. The interactive screen module 8 is electrically connected to the main board 4. The interactive screen module 8 includes a display screen and a control circuit. During operation, the user inputs operation commands by pressing the buttons 9. The control circuit scans, identifies, and processes the trigger signals of each button 9, and executes the corresponding control logic based on the identification results. On one hand, the control circuit can control the interactive screen to display corresponding menus, parameters, or status information; on the other hand, the control circuit can also send corresponding control commands to the main board 4 to control the display screen 2 to perform screen switching, parameter adjustment, or function selection, thereby realizing human-computer interaction.

[0028] Furthermore, the interactive screen module 8 can also be controlled via touch. In this case, the interactive screen module 8 may include a touch panel and a touch control circuit. When the user touches the interactive area, the touch panel generates a corresponding electrical signal change. The touch control circuit detects and calculates the electrical signal change to obtain the touch position or touch command, and executes the corresponding control operation accordingly.

[0029] Specifically, the motherboard 4 can receive user input from the buttons 9 or touch sensors through an integrated microcontroller unit (MCU), convert it into display control commands, and then send unified parameter adjustment commands (such as brightness, contrast, color temperature, etc.) to the motherboard 4 via communication buses such as I²C or SPI. Thus, the centralized and synchronous setting of multi-screen display parameters can be completed physically with only one set of buttons.

[0030] In the dual-screen control scenario of this embodiment, the interactive screen module 8 is electrically connected to the motherboard 4. After the user inputs control commands through button operation or touch operation, the motherboard 4 parses the commands and sends corresponding display control signals to the two display screens 2 respectively, so that the two display screens can display the same content synchronously or display different content respectively, thereby realizing synchronous control or split-screen control of the two display screens.

[0031] The motherboard 4 has a power-on interface 16, which is located on the side of the bracket 3. Interface 16 can be HDMI, DP, USB-C, power interface, etc., and there are no restrictions on its specific type; it can be selected according to the actual situation.

[0032] In the above solution, by controlling the two displays 2 under the same motherboard 4 and uniformly setting the interactive screen module 8 and physical buttons 9 on the back panel 1, the traditional discrete layout of each display 2's buttons and OSD menus being physically locked and unable to be centrally managed is broken. This allows users to seamlessly control both displays 2 from a unified location without having to move their bodies or switch between the two displays 2, truly achieving centralized management and smooth interaction of multiple screens and eliminating barriers to cross-screen operation. At the same time, utilizing the centralized control capability of the motherboard 4, combined with the integrated control menu displayed by the interactive screen module 8, the brightness, color temperature, and other parameters of the two displays 2 can be simultaneously calibrated with a single click using button 9. This simplifies the cumbersome "single-screen loop setting" in the traditional solution into "multi-screen parallel response," significantly reducing the frequency and time loss of collaborative operations, ensuring a high degree of uniformity in visual output, and realizing a synchronized setting mechanism for underlying linkage. Furthermore, this application separates the interactive feedback interface from the two displays 2 and migrates it independently to the interactive screen module 8 located on the back panel 1. All status information during parameter adjustment is centrally displayed on this additional screen, ensuring that the two displays 2 are completely free from visual interference and obstruction from the menu layer when processing business content in full screen. This guarantees the continuity and integrity of the information displayed on the displays 2 and achieves non-intrusive, non-obstructive adjustment. Moreover, by integrating the button 9 and the interactive screen module 8 onto the back panel 1, this application provides an intuitive logical operation entry point while maintaining the simplicity and orderliness of the device's appearance without changing the existing thickness and front-end integration of the displays 2. It simultaneously meets the balance requirements of good tactile feedback and compact structure within a limited space.

[0033] The back panel 1 has a groove 10 on its side, and the button 9 is located in the groove 10.

[0034] A handle hole 13 is provided on the back panel 1. The purpose of the handle hole 13 is to allow the palm to pass through the handle hole 13 so as to lift the entire dual-screen display device.

[0035] In this technical solution, a storage section 14 is provided on the back plate 1, and a first hinge 6 is provided inside the storage section 14; wherein, the first hinge 6 is also a damping hinge, and its working principle is the same as that of the second hinge 11, which is used to allow the bracket 3 to stay at any tilt angle, thereby facilitating the adjustment of the tilt angle of the back plate 1.

[0036] The bracket 3 can rotate around the axis of the first hinge 6, allowing the bracket 3 to switch between a stored state inside the storage section 14 and a supporting state for supporting the back plate 1.

[0037] Furthermore, from Figure 6As can be seen, the storage part 14 is a through hole, and the storage part 14 penetrates the back plate 1 along the thickness direction of the back plate 1. When the bracket 3 is in the storage state, the two plates of the bracket 3 are flush with the two plates of the back plate 1, ensuring that there are no protrusions on the two plates of the back plate 1.

[0038] In this technical solution, such as Figure 4 and Figure 5 As shown, interface 16 is located on the side edge of bracket 3; when bracket 3 is in the retracted state, interface 16 faces the inner wall of the storage part 14. That is, interface 16 is also in the retracted state at this time, and dust and other impurities in the external environment will not enter the interior of interface 16.

[0039] To improve the stability of the bracket 3 during the support process, in this technical solution, an anti-slip pad 7 is fixedly installed on the side edge of the bracket 3 away from the first hinge 6. The anti-slip pad 7 is made of rubber and has a rough surface, which can increase the friction between it and the support surface.

[0040] Furthermore, a limiting frame 15 is fixedly installed inside the storage section 14. The limiting frame 15 is used to limit the position of the support 3 when it is in the stored state. That is, the limiting frame 15 is provided so that when the support 3 contacts the limiting frame 15, the support 3 is in the optimal stored state, that is, at this time, the two plates of the support 3 are flush with the two plates of the back plate 1. In addition, the limiting frame 15 also has the function of enhancing the structural strength of the entire back plate 1.

[0041] like Figure 3 , Figures 6-9 As shown, in this technical solution, protruding brackets 12 are fixed on both sides of the back plate 1. The protruding brackets 12 protrude from one of the surfaces of the back plate 1, and the height of the protruding portion is greater than or equal to the thickness of the display screen 2. During actual installation, the protruding brackets 12 are fixedly connected to the back plate 1, and the display screen 2 is hinged to the protruding brackets 12 via a second hinge 11. The advantage of this installation method is that when folding and storing the two display screens 2, there is no need to follow a fixed order. For example, in this technical solution, the left display screen 2 can be folded and stored first, followed by the right display screen 2, resulting in the following final structure: Figure 9 As shown; the right display screen 2 can be folded and stored first, then the left display screen 2 can be folded and stored, resulting in the final stored structure as shown. Figure 8 As shown, this improves the convenience of storage and prevents damage to the display screen 2 due to incorrect folding order, thus enhancing safety.

[0042] In addition, in this technical solution, the screen of the interactive screen module 8 can face the folded display screen 2, thus achieving effective protection for the interactive screen module 8.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
