[0021] To make the objectives, features, and advantages of this patent more apparent and understandable, the technical solutions in the embodiments of this patent will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this patent without inventive effort are within the scope of protection of this patent.

[0022] Referring to Figures 1 and 2, the display device provided in this patent embodiment includes: a first display area 1 and a second display area 2, which are rotatably connected. The first display area 1 and the second display area 2 have switchable first and second states. The first state indicates that the first display area 1 and the second display area 2 are located on the same plane. The second state indicates that the second display area 2 is folded relative to the first display area 1, that is, the angle of the second display area 2 relative to the first display area 1 changes. The display device provided in this patent embodiment can flexibly adapt to the spatial requirements of different usage scenarios by switching between the first state (coplanar) and the second state (folded). The functional partitioning design of the first and second display areas enables a single device to have multiple functions, reducing reliance on additional auxiliary equipment.

[0023] In one embodiment, the second display area 2 is folded relative to the first display area 1. This can be understood as at least a portion of the second display area 2 rotating upward relative to the first display area 1, such that the angle between the first display area 1 and the second display area 2 is less than 180°.

[0024] The folding design of the first display area 1 and the second display area 2 allows for functional partitioning. For example, the first display area 1 can serve as the main display area to show core content, while the second display area 2 can serve as an auxiliary operation area, such as an input panel or a quick control area, when folded.

[0025] In the second state, the second display area 2 is folded relative to the first display area 1, and the end of the second display area 2 away from the first display area 1 is rotated upward, so that the second display area 2 can form a platform for placing items or for operation input, and can display manuscripts or serve as a typing area.

[0026] Optionally, the display device also includes a display screen, which can be a flexible screen. The area of ​​the display screen on the surface of the first display area 1 forms the main display screen, and the area of ​​the display screen on the surface of the second display area 2 forms the second display screen. In the first state, the first display area 1 and the second display area 2 are coplanar, forming a large display area. In the second state, the first display area 1 and the second display area 2 can form a platform for placing items or for inputting operations, and can display drafts or serve as a typing area.

[0027] Optionally, the display screen can be made of translucent glass. Alternatively, the display screen can be a flexible screen, which is a bendable and foldable flexible display screen. Alternatively, the display screen can be a transparent flexible screen combined with a traditional screen, with the upper flexible screen slightly bent and rolled back. The flat display screen located in the second display area can serve as a second screen for operation, protruding using a structure to become a platform, and its viewing angle can be adjusted to present typing and display modes. This embodiment can improve the efficiency of work meetings; when not in use, it can serve as a general partition, aesthetically pleasing and easy to store, and convenient for dividing space, reducing the material and processing pollution associated with traditional office partition decoration; combined with multiple different modes of function, it further achieves the goal of energy saving.

[0028] Optionally, the support component 3 includes a transparent or semi-transparent support structure. The display screen is laid on the outer periphery of the support structure, and a curtain is installed inside the support structure. The curtain can be opened or closed. During a meeting, the flat display screen located in the second display area of ​​the second body can be used as a second screen for operation, displaying either a typing mode or a control mode. For example, during a meeting, the lower second screen area of ​​the display screen can be adjusted and extended for use as a platform, which can be used to display prompts or as a typing area when giving presentations. When not in a meeting, the curtain can be opened, allowing the display device to be neatly stored as a screen and easily distinguishing spaces.

[0029] Optionally, the display screen can be a semi-transparent glass monitor with an adjustable curtain between the two glass panels, allowing the space to have both visual transparency and privacy. All modes can be manually adjusted.

[0030] In some specific embodiments, the second display area 2 includes a first part 21 and a second part 22. One side of the first part 21 is rotatably connected to the first display area 1, and the other side of the first part 21 is rotatably connected to the second part 22. In a first state, the first display area 1, the first part 21 and the second part 22 are located on the same plane. In a second state, the first part 21 is folded relative to the first display area 1 and the first part 21 is folded relative to the second part 22.

[0031] The folded structure formed by the first part 21 and the second part 22 allows for a more detailed functional division of the second display area 2. The first part 21 can serve as a display area, such as a content preview or operation menu; the second part 22 can serve as an independent interactive area, such as an input panel or shortcut key area.

[0032] The rotation axes of the first part 21 and the second part 22 can distribute the weight load of the second display area 2, avoiding accelerated wear caused by concentrated force on a single rotation axis during single-stage folding. During folding, the sequential folding of the two-stage structure makes the contact between the components more snug, reducing wobbling gaps. Based on the fact that the second display area 2 can be folded relative to the first display area 1, the second display area 2 adopts a two-stage rotation connection design with foldable first part 21 and second part 22 to further enhance the scene adaptability and functional extensibility of the display device. This enables the display device to achieve a better balance in terms of space utilization, user experience, and functional diversity, effectively solving the functional limitations of traditional integrated or single-stage folding structures in complex scenarios.

[0033] Referring to Figures 2 and 3, the second display area 2 is movable relative to the first display area 1. As shown in Figure 2, in the second state, when the second display area 2 and the first display area 1 are in a first relative position, the first display area 1 has a first display area. As shown in Figure 3, when the second display area 2 is in a second relative position, the first display area 1 has a second display area, and the first display area and the second display area are different.

[0034] Optionally, if the first relative position is lower than the second relative position in the vertical direction, and the first display area is larger than the second display area, the second display area 2 is moved to the second relative position, and the first display area 1 is the first display area. If the second display area 2 is moved to the second relative position, the first display area 1 is reduced to the second display area.

[0035] The movement of the second display area 2 not only adjusts the display area but also simultaneously achieves coordination between the display range and the operating space. For example, when the second display area 2 moves to a second relative position and the display area of ​​the first display area 1 becomes smaller, the second display area 2 itself can simultaneously serve as an auxiliary operating platform, such as a keyboard or a display area for manuscripts or typing areas during presentations, facilitating reading and operation for the user. Participants behind can still view the first display area 1 without being affected, eliminating the need to carry a separate computer for input. This avoids the problem of the function and space being disconnected in traditional fixed-area display devices.

[0036] As shown in Figures 1, 4, 5, and 6, the device also includes a support member 3. The support member 3 provides a stable foundation for the first display area 1, which is situated on the support member 3. The ends of the first part 21 and the second part 22 that are far apart from each other are rotatably connected to the support member 3. This rotatable connection between the ends of the first part 21 and the second part 22 forms a symmetrical force-bearing structure with fixed ends and a central linkage, ensuring structural stability during device switching (unfolding / folding) and daily operation, thus extending its service life.

[0037] The support member 3 is provided with a guide groove 34, and the end of the second part 22 away from the first part 21 slides in engagement with the guide groove 34. The guide groove 34 provides a clear path for the movement of the second part 22, so that the first part 21 and the second part 22 always move in tandem along a preset trajectory during unfolding or folding. For example, when switching to the second state (folding), the end of the second part 22 slides along the guide groove 34, which can precisely match the first part 21 and rotate synchronously to the target angle, improving the smoothness of the switching and avoiding structural damage caused by component interference.

[0038] Support component 3 can serve as the reference support unit for the device, adapting to the placement requirements of different usage scenarios. When designed as a movable bracket, support component 3 can flexibly adjust the placement position of the entire device; when designed as a fixed desktop base, it can be stably placed on an office desk. The connection method between the first part 21, the second part 22 and support component 3 allows them to fit snugly against support component 3 when unfolded, reducing the overall space occupied by the device and making it suitable for space-constrained scenarios such as compact office environments and temporary meeting spaces.

[0039] In some specific embodiments, a driving element 33 is also included. The driving element 33 is disposed on the first part 21 and is used to drive the first part 21 to switch the first display area 1 and the second display area 2 between a first state and a second state. The driving element 33 can provide driving force and can directly drive the first part 21 or indirectly drive the first part 21.

[0040] Optionally, the drive component 33 can be a knob, which is directly connected to the rotating shaft of the first part 21, which can simplify the transmission path and reduce the space occupied by the structure.

[0041] Optionally, the drive component 33 can transmit power through mechanisms such as gear sets, belt drives, or linkages to distribute the driving force load, adapt to complex multi-component synchronous operation requirements, and improve design adaptability. Referring to Figures 4 to 9, the height and angle of the first part 21 can be changed by rotating the drive component 33. The drive component 33 can be a handle. Figure 4 shows the first display area 1 and the second display area 2 at 180°, Figure 5 shows the first part 21 of the first display area 1 and the second display area 2 at 145°, and Figure 6 shows the first part 21 of the first display area 1 and the second display area 2 at 90°.

[0042] Referring to Figures 10, 11, and 12, the support member 3 includes a first bracket 31 and a second bracket 32, which are slidably engaged. A first display area 1 is disposed on the first bracket 31, and a second display area 2 is disposed on the second bracket 32, so that the second display area 2 can switch between a first relative position and a second relative position. Optionally, the ends of the first part 21 and the second part 22 that are far apart from each other are rotatably connected to the second bracket 32.

[0043] Figure 10 can be shown as a schematic diagram of the second display area 2 in the first relative position, and Figures 11 and 12 can be shown as schematic diagrams of the second display area 2 in the second relative position; in the second relative position, the height of the second display area 2 is higher than that in the first relative position.

[0044] The sliding engagement of the first bracket 31 and the second bracket 32 ​​provides a stable and linear movement path for the second display area 2, allowing for precise control of the switching between the first and second relative positions. Optionally, when switching to the first relative position, the display area of ​​the first display area 1 is simultaneously increased to meet the panoramic display requirements of multi-person conferences; when switching to the second relative position, the second bracket 32 ​​moves the second display area 2, reducing the display area of ​​the first display area 1. The sliding engagement of the first bracket 31 and the second bracket 32 ​​enables continuous fine-tuning of the position, avoiding display interruptions caused by position jumps and improving switching accuracy and efficiency.

[0045] The first bracket 31 stably supports the first display area 1, and the second bracket 32 ​​is tightly fitted to the first bracket 31 through a sliding structure to prevent the second display area 2 from shaking or falling due to cantilever installation. At the same time, the sliding contact surface can be designed as a high-precision guide rail structure. The guide rail structure can use grooves and protrusions and rollers to assist sliding, reducing the frictional resistance when the second bracket 32 ​​moves. This ensures smooth sliding and prevents the bracket from shifting or falling off through mutual limiting of the contact surfaces, ensuring that the device remains structurally stable during position switching and daily use.

[0046] Optionally, a positioning buckle can be added to the sliding path of the second bracket 32 ​​to fix the second display area 2 in a specific position.

[0047] As shown in Figures 7, 8, and 9, the second bracket 32 ​​is provided with an arc-shaped groove 321, and the second display area 2 is provided with a protrusion. The protrusion slides in conjunction with the arc-shaped groove 321 to allow the first display area 1 and the second display area 2 to switch between a first state and a second state. The arc-shaped groove 321 provides a specific movement path for the protrusion, enabling the second display area 2 to slide along a preset arc-shaped trajectory when switching states, allowing the display device to have a switchable first state (coplanar) and a second state (folded). The arc-shaped groove 321 plays a good guiding and limiting role for the protrusion. During the sliding process, the protrusion is always confined within the arc-shaped groove 321, preventing the second display area 2 from shifting or shaking during movement, thus enhancing the stability of the structure and making the display device more stable and reliable when switching states. The arc-shaped groove 321 ensures the accuracy and consistency of the movement, avoiding component interference or positional deviation problems caused by uncertain movement trajectories, thereby ensuring that the display device switches stably and accurately between the first state and the second state.

[0048] In some specific embodiments, a locking structure is also included; when the second display area 2 is in the first relative position or the second relative position, the locking structure is locked; when the second display area 2 switches between the first relative position and the second relative position, the locking structure is unlocked.

[0049] When the second display area 2 is in the first relative position (the first display area 1 has a larger display area) or the second relative position (the first display area 1 has a smaller display area), the locking structure automatically locks, which can fix the relative position of the second display area 2 and the support member 3 (or the first display area 1), prevent the second display area 2 from shifting due to accidental touch or vibration during use, ensure the stability of the display area of ​​the first display area 1, and ensure the structural reliability in the usage scenario.

[0050] The locking structure forms an operation protection mechanism through the logic of locking and unlocking in place. It only needs to be unlocked when switching states. After the position adjustment is completed, the locking structure will automatically take effect, preventing accidental sliding of the second display area 2 and improving operation safety and convenience.

[0051] Referring to Figures 10, 11, 12, 13, and 14, the first bracket 31 is provided with a sliding groove 313, a first through hole 311, and a second through hole 312. The first through hole 311 and the second through hole 312 are respectively located at both ends of the sliding groove 313 and communicate with the sliding groove 313. The diameters of the first through hole 311 and the second through hole 312 are larger than the width of the sliding groove 313. The locking structure includes a first locking member 4 and a second locking member 5. The first locking member 4 is sleeved on the outside of the second locking member 5, and the first locking member 4 and the second locking member 5 are engaged. The outer diameter of the first locking member 4 is larger than the width of the sliding groove 313, and the outer diameter of the first locking member 4 is smaller than the diameter of the first through hole 311 and the second through hole 312. The outer diameter of the second locking member 5 is smaller than the width of the sliding groove 313. Optionally, springs may be provided inside the first locking member 4 and the second locking member 5 to assist in tensioning. When the first locking member 4 is pulled outward relative to the second locking member 5, the locking structure unlocks; when the first locking member 4 is pushed inward, the locking structure locks. Pulling out the first locking member 4 allows adjustment of the height and angle of the second display area 2 for quick adjustment to the desired meeting mode. When typing is required for temporary content modifications, the user can rotate the drive member 33 to change the angle of the second display area 2 and pull the first locking member 4 to change the height of the lower second display area 2, facilitating fast typing at a seated height. The first part 21 of the second display area 2 can serve as a second small screen workspace, convenient for the user to read and operate, while participants behind can still clearly see the large screen without being affected, eliminating the need to carry a separate computer for input.

[0052] Optionally, the first locking member 4 includes a first limiting protrusion 41, and the second locking member 5 includes a second limiting protrusion 51, as shown in FIG14. When the first locking member 4 and the second locking member 5 are unlocked, the first limiting protrusion 41 abuts against the second limiting protrusion 51, so that the first locking member 4 and the second locking member 5 are opened but not separated, thus preventing the second locking member 5 from disengaging from the slide groove 313.

[0053] The first through hole 311 and the second through hole 312 correspond to the first and second relative positions of the second display area 2, respectively. When the first locking member 4 moves with the second display area 2 to the first through hole 311 or the second through hole 312, its outer diameter is larger than the width of the slide groove 313 but smaller than the diameter of the through hole. This design allows the first locking member 4 to fall into the through hole to form a physical limit. At the same time, in conjunction with the snap-fit ​​structure of the first locking member 4 and the second locking member 5, a dual fixing effect of mechanical locking and structural locking is achieved. Compared with a single locking method, this design can more reliably prevent the second display area 2 from sliding in the first or second relative position, ensuring the stability of the display area and the position of the operating platform.

[0054] The design of the slide groove 313, which is smaller than the outer diameter of the first locking member 4 but larger than the outer diameter of the second locking member 5, allows the second locking member 5 to slide smoothly along the slide groove 313 (its outer diameter is adapted to the width of the slide groove 313) when the first locking member 4 and the second locking member 5 are unlocked. When the second locking member 5 moves to the first through hole 311 or the second through hole 312, the first locking member 4 and the second locking member 5 engage. The outer diameter of the first locking member 4 is larger than the width of the slide groove 313, so that the locking structure is limited to the first through hole 311 or the second through hole 312.
