Display device and control method thereof

[0001] The present invention relates to a display device and a method for controlling the same.

[0002]

[0003] In conventional casino environments or work environments requiring multiple displays, a method is generally used in which multiple physical monitors (i.e., physical display devices) are used to output each video source.

[0004] This method has the problem of spatial constraints, high installation costs (e.g., the cost of installing multiple frames to secure each physical monitor), and maintenance costs because it requires the installation of multiple physical monitors.

[0005] In particular, for casino gaming machines, surveillance monitor systems, or advertising displays that provide various content through multiple physical monitors, the user's visual experience and the efficient delivery of information are critical; however, existing multi-monitor systems utilizing multiple physical monitors result in installation complexity and control difficulties.

[0006] Therefore, there is a need for technology that can display multiple video sources on a single physical monitor as a split screen, switch a specific video source among multiple sources to full screen when necessary, and clearly distinguish between screens using a digital black border (i.e., a software-implemented border).

[0007] The background technology of the present invention is disclosed in Korean Published Patent No. 10-1920629 (registered Nov. 15, 2018).

[0058]

[0059] FIG. 1 is an exemplary diagram showing the schematic configuration of a display device according to one embodiment of the present invention.

[0060] As illustrated in FIG. 1, the display device according to the present embodiment may include a video input module (110), a video processing module (120), a video distribution module (130), a display module (140), and a processor (210).

[0061] The processor (210) can generate control commands and control the video input module (110), video processing module (120), and video distribution module (130).

[0062] The processor (210) can manage screen modes (e.g., split screen mode, full screen mode).

[0063] The processor (210) can be implemented as a controller (e.g., a control computer) or a server.

[0064] The video input module (110) can receive multiple external video sources (e.g., Video #1, Video #2, Video #3) (or video data).

[0065] For example, the video input module (110) may include an EGM (External Graphics Module).

[0066] Although not specifically illustrated in the drawings, data (e.g., video data, control data, synchronization data, communication protocol data, etc.) can be transmitted to the corresponding components (e.g., video input module, video processing module, video distribution module) through a data communication path.

[0067] For example, video data may include screen information input from each video source (Video #1, Video #2, Video #3, etc.), which refers to digital video data such as image frames, color information, and resolution. Control data may include control commands transmitted from the processor (210) and screen output setting information, such as the screen splitting position, whether to insert and effect of a digital black border, and a command to switch a specific video source to full screen. Synchronization data may include timing and frame synchronization data for synchronizing multiple video sources to output to the display. Communication protocol data may include control signals such as I2C, SPI, and V-by-One according to the communication protocol used for data transmission.

[0068] The video processing module (120) can process the input video data and scale it to fit the screen (SCREEN).

[0069] For example, the video processing module (120) may include an AD Board (Adjustment Board) and can transmit data to the video distribution module (130) through a high-speed data transmission interface (e.g., V-by-One interface).

[0070] The video distribution module (130) can distribute and output multiple video data (e.g., Video#1, Video#2, Video#3) received from the video processing module (120) to each designated screen (SCREEN) of the display module (140).

[0071] For example, the video distribution module (130) can distribute and output multiple video data (e.g., Video#1, Video#2, Video#3) to each designated screen in a plurality of screen areas (e.g., 2, 3, etc.) divided from a full screen area in a single display module (140) (e.g., display panel).

[0072] When the video distribution module (130) divides and outputs video data to multiple screens, it can generate and output (insert) a black border (i.e., a digital black border) in a digital manner (i.e., a software method) to clearly distinguish the boundaries between each screen.

[0073] In this case, the digital black border can improve the user's visual experience by maintaining boundaries even during screen transitions and mode changes.

[0074] The display module (140) can be implemented as a single display panel.

[0075] However, in this embodiment, the display panel uses a curved display panel (hereinafter referred to as a curved display panel) to obtain user image concentration and an optical illusion effect (i.e., an optical illusion effect similar to using multiple physical monitors), as shown in FIG. 7. The specific shape of the curved display panel will be explained with reference to FIG. 7.

[0076] Accordingly, the digital black border can be output (displayed) aligned with the fold (i.e., curved) portion of the curved display panel.

[0077] For reference, the reason for displaying video across multiple monitors in a casino environment is to enable the display of large-scale content (e.g., casino promotional videos, tournament events) that is difficult to show on a single monitor, to provide customers with diverse visual experiences by simultaneously displaying different content on each monitor, and to display information optimized for each zone on various monitors while considering customer movement within the casino.

[0078] However, when outputting video through multiple monitors, as explained in the background technology, the installation of multiple physical monitors is required, which leads to problems such as spatial constraints and high installation and maintenance costs. Accordingly, the purpose of this embodiment is to achieve the effect of using multiple monitors while using a single monitor (i.e., a display module).

[0079] In this case, if only the screen area is divided on a single monitor (i.e., a display module), the feeling or effect of using multiple conventional monitors cannot be expected. Therefore, in this embodiment, a single display panel modified into a curved shape is used to obtain the feeling or effect of using multiple conventional monitors (see FIG. 7).

[0080] FIG. 2 is a flowchart for explaining a control method for a display device according to an embodiment of the present invention. FIG. 3 is a table for explaining the digital black border output according to the screen mode and the effect applied when removing the digital black border in FIG. 2.

[0081] Referring to FIG. 2, the processor (210) checks whether the current display module (140) is set to split screen mode (S101).

[0082] When set to split screen mode (Y of S101), the processor (210) outputs a digital black border to the display module (140) through the video distribution module (130) (S102).

[0083] A digital black border is output to the boundary portions (i.e., fold portions, curvature portions) between each screen (SCREEN) of the display module (140).

[0084] The video distribution module (130) can apply a specified effect (or option) when outputting a digital black border according to a screen mode (e.g., split screen mode) (see FIG. 3).

[0085] For example, referring to FIG. 3, assuming that Effect 1 is a sliding effect, the sliding can proceed from the right (R) to the left (L) when the digital black border is output, and the sliding can proceed from the left (L) to the right (R) when the digital black border is removed. Assuming that Effect 2 is a flipping effect, the flipping can proceed from the upper side (U) to the lower side (D) when the digital black border is output, and the flipping can proceed from the lower side (D) to the upper side (U) when the digital black border is removed. Assuming that Effect 3 is a rotation effect, the rotation can proceed from the right (R) to the left (L) when the digital black border is output, and the rotation can proceed from the left (L) to the right (R) when the digital black border is removed. Assuming that Effect N is a fade effect, the fade can proceed from the right (R) to the left (L) when the digital black border is output, and the fade can proceed from the left (L) to the right (R) when the digital black border is removed.

[0086] The video distribution module (130) distributes and outputs multiple video data (e.g., Video#1, Video#2, Video#3) to each designated screen in each divided screen (SCREEN) area (S103).

[0087] Meanwhile, if the current display module (140) is set to full screen mode (N of S101), the processor (210) removes the digital black border output to the display module (140) through the video distribution module (130) (S104).

[0088] The video distribution module (130) can apply a specified effect (or option) when removing digital black borders according to the screen mode (e.g., full screen mode) (see FIG. 3).

[0089] Referring to FIG. 3, when outputting and removing digital black borders, each effect (e.g., still image, animation, etc.) may be applied in opposite directions, each effect may be applied in the same direction, each effect may not be limited to black but may be applied in other colors, and each effect may have a specific pattern (hatching) applied to the digital black border.

[0090] The video distribution module (130) outputs video data (e.g., any one of Video#1, Video#2, Video#3) that was being output to a designated split screen (SCREEN) area to a full screen (SCREE) area (S105).

[0091] FIG. 4 is an example diagram showing a split screen with a digital black border applied according to one embodiment of the present invention.

[0092] Referring to FIG. 4, a display module (140) (e.g., a single display panel) is divided vertically into three split screens (Screen) and outputs a video source to each.

[0093] Various content, such as Video #1 (e.g., sports match video), Video #2 (e.g., racing game screen), and Video #3 (e.g., slot machine game), is being displayed on each screen.

[0094] A digital black border is inserted between each screen, clearly distinguishing the boundaries between the screens.

[0095] At this time, the digital black border has the effect of preventing visual confusion on the screen and allowing each screen to be recognized as independent content, and as described in Fig. 3, the effect can be applied, and each screen (SCREEN) receives and outputs an individual video source, and a specific screen can be switched to the full screen as needed.

[0096] The digital black border can be automatically removed (e.g., in full-screen mode) or reapplied (e.g., in split-screen mode) when switching screen modes.

[0097] FIG. 5 is an exemplary diagram illustrating a switching function between a split screen mode and a full screen mode according to an embodiment of the present invention.

[0098] Referring to FIG. 5, the split screen mode allows a single display module (140) (e.g., a display panel) to be divided into three independent screens (e.g., Screen #1, Screen #2, Screen #3) to output a video source to each.

[0099] Digital black borders are inserted between each screen to clearly distinguish the boundaries between screens.

[0100] The processor (210) can transmit control signals through the DDC / CI (Display Data Channel / Command Interface) for video source and screen control.

[0101] Here, the control signal may be a signal for managing screen mode changes and output status, and the video source may refer to individual content to be output to each screen.

[0102] Full screen mode allows you to switch a specific screen (e.g., one of Screen #1, Screen #2, or Screen #3) to full screen mode for display.

[0103] When switched to full screen (SCREEN), video sources on other screens are hidden, and digital black borders are removed to display a single screen. When switched back to split-screen mode, the original split-screen layout and digital black borders are restored.

[0104] Split screen mode and full screen mode can be switched according to user or system control signals, and can be designed so that the video source and screen output are maintained without interruption even during switching.

[0105] This screen mode switching method allows full-screen switching to be used when highlighting specific game content on casino gaming machines, and enables specific materials or videos to be enlarged to full screen and displayed during meeting presentations on multimedia displays.

[0106] FIG. 6 is an example diagram to explain the switching function between split screen mode and full screen mode in FIG. 5 in more detail.

[0107] Referring to FIG. 6, in split screen mode, one display module (140) (e.g., display panel) is divided into three split screens (e.g., Screen #1, Screen #2, Screen #3) and outputs a video source to each.

[0108] A control signal (DDC / CI) output from the processor (210) is applied to each screen (SCREEN) to manage video sources and screen settings.

[0109] For example, assuming that a sports match video (Video #1) is displayed on the top screen (Screen 1), a racing game screen video (Video #2) is displayed on the middle screen (Screen 2), and a slot machine game content video (Video #3) is displayed on the bottom screen (Screen 3), a digital black border is inserted between each screen to clearly distinguish the boundaries between the screens.

[0110] In full-screen mode, the user can select a specific screen among the split screens to switch to full-screen mode.

[0111] For example, FIG. 6 is an example diagram showing the state in which a slot machine game content video (Video #3) displayed on the bottom screen (third screen) is switched to full screen mode. When switching from split screen mode to full screen mode, the digital black border is removed, and the video displayed on the selected screen (SCREEN) is displayed on the entire screen.

[0112] Switching between such screen modes (split screen mode ↔ full screen mode) is performed according to user input or control signals.

[0113] Video sources and content are maintained seamlessly when switching screen modes, and among these switching methods, full-screen mode can be used on casino gaming machines when it is necessary to highlight specific game screens. Additionally, screen mode switching methods can be utilized on multimedia displays to highlight presentations or specific content.

[0114] FIG. 7 is an example view taken from the upper side to explain the external shape of the display module in FIG. 1, and visually shows the method of combining the display panel and glass and the change in curvature.

[0115] Referring to FIG. 7, a glass (front) and a display panel (rear) are combined to form a single display module (140).

[0116] At this time, the glass and the display panel each have different curvatures depending on their physical properties, and can be adjusted during the bonding process.

[0117] For example, the glass combined on the front has a relatively large curvature (stronger bending), and the display panel combined on the back has a relatively small curvature (less bending). These structural differences are intended to provide optimal visual effects and structural stability after the display panel is combined with the glass.

[0118] After the combination is completed, a single curved display module (140) is completed with the glass and the display panel integrated.

[0119] Even after combination, the curvature of each element (e.g., glass, display panel) harmonizes to prevent screen distortion and improve the viewing angle. The curved display module (140) provides the user with visual immersion and has the effect of contributing to reducing screen reflection and distortion. In particular, it can enhance the user experience in environments such as casino gaming machines or multimedia displays.

[0120] FIG. 8 is an example diagram illustrating a method of outputting a digital black border by dividing a single display module into three screens in FIG. 1.

[0121] Referring to Fig. 8, assuming the display panel has a resolution of 2160 x 3840 pixels and an aspect ratio of 9:16, the entire display panel can be used as a single screen by default, or it can be divided into three split screens (Screen #1, Screen #2, Screen #3). In this case, the resolution of each split screen can be set to 2160 x 1215 pixels and the aspect ratio can be set to 16:9, and different video sources can be output to each split screen. Additionally, a digital black border can be inserted between each split screen (i.e., at the boundary) to clearly distinguish the boundaries between screens. In this case, the digital black border prevents confusion between the content displayed on each screen and improves the user's visual concentration.

[0122] Meanwhile, when the user selects a specific screen to switch to full-screen mode, the digital black border is removed, and the video displayed on the screen selected by the user is output across the entire display area. When returning to split-screen mode after switching to full-screen mode, the digital black border is reapplied.

[0123] As such, the present embodiment enables screen splitting and switching to a full screen depending on the screen mode, thereby allowing various content to be provided simultaneously on a multimedia display or casino game machine.

[0124] In addition, rather than simply performing software-based screen area division, a curved display module (140) (e.g., a curved display panel) is formed by applying physical curvature, thereby creating an optical illusion that makes it appear as if multiple physical display modules are combined, which can improve the user experience.

[0125] FIG. 9 is an example diagram illustrating a method of outputting a digital black border by dividing a single display module into two screens in FIG. 1.

[0126] Referring to FIG. 9, when a display panel with a resolution of 2160 x 2538 pixels is divided into two screens (Screen #1, Screen #2), each divided screen has a resolution of 2160 x 1215 pixels and an aspect ratio of 16:9. The two divided screens can be arranged vertically and can output different video sources.

[0127] A digital black border is inserted between the two screens to clearly distinguish the boundary between them. The digital black border serves to prevent confusion between content and enhance visual focus.

[0128] Different video sources are displayed on each split screen, and the video from a specific screen can be switched to full screen as needed. Digital black borders are removed when switching to full screen mode, and are reapplied when returning to split screen mode.

[0129] The present embodiment has the effect of providing various content to the user in a clearly distinguishable state by dividing a single display panel into multiple screen areas, outputting multiple video sources through each screen area, and inserting a digital black border between each screen.

[0130] This embodiment has the effect of providing flexibility in screen switching and improving user convenience in various work and content display environments by controlling a specific video source to switch to full screen as needed and return to a multi-screen state.

[0131] This embodiment has the effect of enabling a single display device to satisfy the display requirements for various content by outputting multiple video sources to a single physical monitor, dynamically changing the screen layout as needed, and displaying the screen boundaries (or borders) using a digital black border.

[0132] This embodiment has the effect of reducing the complexity of installation and maintenance associated with existing multi-monitor systems by integrating screen splitting and switching functions, and providing a display solution suitable for various industrial environments such as monitoring systems, gaming devices, and advertising panels.

[0133] The implementations described herein may be implemented, for example, as methods or processes, devices, software programs, data streams, or signals. Even if discussed only in the context of a single form of implementation (e.g., discussed only as a method), the implementation of the discussed features may also be implemented in other forms (e.g., devices or programs). Devices may be implemented in appropriate hardware, software, and firmware, etc. Methods may be implemented in devices such as processors, which generally refer to processing devices including, for example, computers, microprocessors, integrated circuits, or programmable logic devices. Processors also include communication devices such as computers, cell phones, portable / personal digital assistants ("PDAs"), and other devices that facilitate the communication of information between end-users.

[0134] Although the present invention has been described above by limited embodiments and drawings, the present invention is not limited thereto, and it is obvious that various modifications and variations are possible within the scope of the technical spirit of the present invention and the equivalent scope of the claims described below by those skilled in the art to which the present invention belongs.
