Description

Vehicle display device and its operating method

[0001] The present invention relates to a vehicle display device and an operating method thereof, and more particularly, to a vehicle display device and an operating method thereof that enable selective light blocking of a transparent display.

[0002] To ensure the safety and convenience of vehicle users, vehicles are equipped with various sensors and devices, and their functions are diversifying. These vehicle functions can be divided into convenience functions, which promote driver convenience, and safety functions, which ensure the safety of drivers and / or pedestrians.

[0003] Convenience features in vehicles are developed with driver convenience in mind, such as providing infotainment (information + entertainment) capabilities, supporting partial autonomous driving, or helping drivers secure their field of vision, such as at night or in blind spots. Examples include active cruise control (ACC), smart parking assist system (SPAS), night vision (NV), head-up display (HUD), around view monitor (AVM), and adaptive headlight system (AHS).

[0004] Additionally, the vehicle's safety features are technologies that ensure the safety of the driver and / or pedestrians, such as the lane departure warning system (LDWS), lane keeping assist system (LKAS), and autonomous emergency braking (AEB).

[0005] Recently, technologies are being studied to display and share various guidance information related to safe driving and driver safety on the exterior of a vehicle.

[0006] In particular, display systems that incorporate augmented reality (AR) technology into vehicles, projecting content such as driving routes, obstacle information, and speed warnings onto the windshield or projecting them onto the outside, enabling intuitive recognition by drivers and pedestrians, are attracting attention. These technologies have the potential to reduce distraction while driving and enhance the efficiency of road traffic.

[0007] Meanwhile, these external display devices must ensure clear visibility under various external environmental conditions, such as day or night, clear days or rainy / snowy conditions, and for this purpose, light-blocking technology for transparent displays is also required.

[0008] In particular, transparent displays based on TOLED (Transparent OLED) are structured so that the outside is visible when no content is displayed, so it is becoming important to combine them with a light-blocking structure to emphasize only specific information or adjust the contrast with the outside background.

[0009] In this regard, for example, U.S. Patent Publication No. US 2023-0228988 (hereinafter, "Prior Art 1") discloses a technology for controlling the light transmission characteristics of a space formed between a plurality of transparent members by accommodating first and second fluids in the space. However, Prior Art 1 does not disclose any configuration for dynamically and independently controlling the exposure position and degree of light blocking of a display depending on the operating mode of the display device, and therefore, there are limitations in linked control or flexible light blocking adjustment according to the driving state or environmental conditions of the vehicle.

[0010] Accordingly, there is a need for a technical solution capable of independently or in conjunction with the display's exposure and shading state, depending on various driving modes and content types. Against this backdrop, the present invention proposes a vehicle display device capable of providing information optimized for various user experiences and driving situations, based on the display's pop-up operation and shading fluid control.

[0011] The present invention aims to solve the above-mentioned problems and other problems.

[0012] According to some embodiments of the present invention, the purpose is to provide a vehicle display device in which the transparent display itself has a structure that can move up and down (pop-up), and the exposure height and light-blocking state of the display can be independently controlled according to the driving state or driving mode.

[0013] In addition, according to some embodiments of the present invention, the purpose is to provide a vehicle display device capable of more flexibly adjusting the degree of light blocking of a transparent display by controlling the types of transparent fluid and opaque fluid introduced and the inflow / discharge speed and ratio through a fluid-based light blocking module disposed on the back surface of the transparent display.

[0014] Furthermore, according to some embodiments of the present invention, another object is to provide a vehicle display device capable of implementing display conditions suitable for various contents such as augmented reality (AR) information, driving status information, and video contents by differently setting the position and / or shading range of the display in response to multiple driving modes.

[0015] To this end, the vehicle display device according to the present invention can selectively shade at least a portion of a transparent display or vary the degree of shade.

[0016] At this time, the degree of light blocking of the transparent display may vary depending on the driving mode of the transparent display that operates to be moved vertically. The different driving modes include not only cases where the height of the transparent display changes depending on the vertical movement of the transparent display, but also cases where the display mode of the transparent display changes depending on the properties of the displayed content, display, driving status, etc.

[0017] Specifically, a vehicle display device according to an embodiment of the present invention includes a transparent display formed to have different exposure heights by moving up and down; a light-shielding module disposed on a rear surface of the transparent display and formed to allow fluid to be selectively injected into an internal space; a fluid supply unit that operates in conjunction with the light-shielding module to inject or discharge at least one of a transparent fluid and an opaque fluid into the internal space; and a processor that controls the movement of the transparent display in the up and down direction and the operation of the fluid supply unit. At this time, the processor controls the exposure height according to the movement of the transparent display in the up and down direction based on different driving modes and adjusts the degree of light-shielding of the transparent display by injecting or discharging a fluid contained in the internal space of the light-shielding module according to the operation of the fluid supply unit, wherein the control of the exposure height of the transparent display and the adjustment of the degree of light-shielding are performed independently.

[0018] In an embodiment, the processor may control, in the first driving mode, the exposure height of the transparent display to the outside to be minimized, and may control the injection of an opaque fluid contained in the internal space of the shading module to be greater than a reference value.

[0019] In an embodiment, the processor may control the external exposure height of the transparent display to be higher in the second driving mode than in the first driving mode, and control the operation of the fluid supply unit to inject an opaque fluid contained in the internal space of the light-shielding module to a level below a reference value, thereby adjusting the degree of light-shielding of the transparent display.

[0020] In an embodiment, the processor controls, in the third driving mode, the transparent display to rise to a full exposure state higher than that in the second driving mode, and controls the operation of the fluid supply unit so that the entire internal space of the shading module is filled with an opaque fluid, thereby completely shading the transparent display.

[0021] In an embodiment, the processor may control at least one of the outflow speed and outflow amount of the opaque fluid in the internal space of the shading module differently in response to the rising speed of the transparent display when switching from the first driving mode to the second driving mode.

[0022] In an embodiment, the processor may control at least one of an inflow rate and an inflow amount so that, when returning from the second driving mode to the first driving mode, the opaque fluid filling the internal space of the shading module is injected to a position corresponding to the first driving mode.

[0023] In an embodiment, the processor may control at least one of the height control and the degree of light blocking of the transparent display to correspond to the first driving mode based on whether the vehicle is switched from an autonomous driving mode or a stopped state to a manual driving mode.

[0024] In an embodiment, the processor may switch to the first driving mode or to a preset driving mode based on detecting a change in the vehicle's ignition off or on status, and control the amount of fluid in the internal space of the shading module based on this.

[0025] In an embodiment, the processor controls the exposure height by raising the transparent display, and controls at least one of the flow rate and flow amount of the opaque fluid in the internal space of the shading module so that the transparent display has a shading area and a non-shading area that are distinguished from the upper and lower portions, and the driving status information of the vehicle can be displayed in the shading area, and the driving guide information can be displayed in the non-shading area.

[0026] In an embodiment, the fluid supply unit comprises a first flow control unit containing an opaque fluid and a second flow control unit containing a transparent fluid, and the first and second flow control units may include a flow path connected to the internal space of the shading module through each of the inlets and outlets.

[0027] In an embodiment, the fluid supply unit includes a first drive module for controlling the flow rate of opaque fluid corresponding to the first flow rate control unit and a second drive module for controlling the flow rate of transparent fluid corresponding to the second flow rate control unit, and the processor can control the first and second drive modules with different torques or drive pressures to differently control the ratios of transparent fluid and opaque fluid included in the internal space.

[0028] In an embodiment, the control of transparent and opaque fluid flow rates according to the operation of each of the first and second driving modules may be performed by at least one of an electronic valve, a pressure pump, and a quantitative injection module.

[0029] In an embodiment, the processor may adjust the exposure height and the degree of light blocking of the transparent display based on preset profile data according to the different driving modes.

[0030] In an embodiment, in the display device, the degree of shading according to the preset profile data may be varied based on user input or data received from a light sensor or weather sensor outside the vehicle.

[0031] In an embodiment, the fluid supply unit is configured to inject or discharge the opaque fluid through a first inlet corresponding to the first flow path and a second inlet corresponding to the second flow path, and the processor can, when injecting or discharging the opaque fluid through the first and second inlets according to a change in the driving mode, differently control at least one of the inflow or outflow speed and time of the opaque fluid introduced or discharged through the first and second flow paths.

[0032] In an embodiment, the processor may control at least one of the opening time and pump pressure of each injection valve corresponding to the first and second euros to control the inflow or outflow rate of the opaque fluid.

[0033] In an embodiment, the processor can adjust the inflow ratio and speed of transparent fluid and opaque fluid flowing into the internal space of the shading module differently according to a change in the driving mode.

[0034] In an embodiment, the processor may control the inflow or outflow of the opaque fluid so that the height of the opaque fluid varies in response to a content display area displayed on the transparent display.

[0035] In an embodiment, the processor may control the up and down movement of the transparent display depending on the inflow or outflow rate of the opaque fluid.

[0036] The effects of the vehicle display device and its operating method according to the present invention are described as follows.

[0037] Specifically, according to the vehicle display device and its operating method according to some embodiments of the present invention, the exposure height and the degree of light blocking of the transparent display can be controlled independently from each other, so that various display environments can be flexibly implemented depending on the driver, driving status, and / or system settings.

[0038] Additionally, the position and intensity of the shading can be finely adjusted depending on the type of fluid, inflow / outflow speed, and inflow path, thereby providing more suitable visibility and immersion depending on the external lighting or content type.

[0039] Additionally, since automatic control linked to vehicle data such as the vehicle's driving status, autonomous driving status, stop detection, and engine status can be used to maintain an optimized display status for the situation without user intervention, both safety and convenience are improved.

[0040] Furthermore, by independently controlling multiple shading modules or shading areas, it becomes possible to implement a user experience-based display that can display information separately by upper / lower or left / right areas, or emphasize AR content without obstructing driving or vision.

[0225] Hereinafter, the vehicle display device (800) and its operation according to an embodiment of the present invention will be described in more detail with reference to FIGS. 7 and 10.

[0226] A vehicle display device (800) according to an embodiment of the present invention is mounted on a vehicle (100) and configured to adaptively control the display state and light-blocking state of the display according to the driving state of the vehicle or the external environment.

[0227] A vehicle display device (800) includes a transparent display (810) that can move up and down, a light-blocking module (820) that is positioned on the back of the transparent display (810) and can selectively block light, a fluid supply unit (830) that controls the injection and discharge of fluid in conjunction with the light-blocking module (820), and a processor (840) that controls the operation of these components. However, this does not mean that the device is limited to this configuration, and may include fewer or more configurations.

[0228] The transparent display (810) may be formed, for example, with a TOLED (Transparent Organic Light Emitting Diode) structure. The transparent display (810) may be stored in a portion of the vehicle dashboard or center fascia during normal driving conditions, and may pop up upwards to perform an expanded display function as needed. The transparent display (810) serves as a display means for visually providing driving guidance, augmented reality-based information, vehicle status information, and / or entertainment information.

[0229] The shading module (820) is positioned on the back surface of the transparent display (810). The shading module (820) includes a single or multiple spaces formed so that transparent fluid and / or opaque fluid can be selectively injected. These spaces can be subdivided into fine cell or pattern structures, and the light transmittance or opacity of each region can be adjusted depending on the type and injection ratio of the fluid.

[0230] The fluid supply unit (830) may be independently configured for transparent fluids and opaque fluids, and may include a first flow control unit and a second flow control unit for controlling the flow of each fluid. In addition, fluid control means such as an electronic valve, a pressure pump, and a quantitative injection module for injecting or discharging fluids are included, enabling more precise shading control.

[0231] The processor (840) is a central control unit that controls the overall operation of the vehicle display device (800), and independently controls the raising / lowering operation of the transparent display (810) and the injection / discharge of the fluid included in the shading module (820) by considering various conditions such as the vehicle's driving mode, ambient lighting, weather information, and user settings. This makes it possible to simultaneously secure visibility of the display and clarity of driving information transmission.

[0232] Through this configuration, the vehicle display device (800) of the present invention operates as an improved driver assistance system that goes beyond a simple display function and provides visual information optimized for the external environment and flexibly controls light blocking.

[0233] Although not disclosed in the drawing, according to another embodiment of the present invention, the processor (840) can control the display of information content in the form of augmented reality (AR) through the transparent display (810) based on the driving status, location, speed, external sensor information, and content data of the vehicle.

[0234] More specifically, the processor (840) generates AR content visualizing driving path, speed information, road signs or obstacle information around the vehicle based on data received from an ADAS system, navigation, or an external server, and can display the AR content in real time on the front of the transparent display (810).

[0235] The AR content may be configured to be positioned on different depth planes depending on the type. For example, immediate information, such as speed or warning icons, may be displayed on a near plane near the user's eyes, lane guidance lines or directional arrows may be rendered on a mid-distance plane, and information related to intersections or destinations may be rendered on a far plane.

[0236] Additionally, the processor (840) can control the depth, position, and size of AR content to be dynamically adjusted based on the vehicle's driving speed, ambient lighting, weather, or user input. For example, when driving at night, warning content can be relatively enlarged and displayed in a nearby area ahead, and when driving at high speeds, the content's position can be adjusted to a farther area so that it can be naturally recognized without the driver having to move their gaze.

[0237] The position adjustment of the AR content as described above can be set differently depending on the display depth plane on the transparent display (810). Accordingly, the processor (840) can control the fluid supply unit (830) linked to the shading module (820) to inject an opaque fluid into the background of the corresponding area to improve the visibility of a specific depth plane, and can also adjust the concentration of the transparent fluid corresponding to the content display area.

[0238] With this configuration, the multiple AR contents presented to the user on the transparent display (810) can provide clearer and more intuitive visual effects. Accordingly, both the efficiency of information recognition and safety during driving can be improved.

[0239] FIG. 8 is an exemplary drawing showing the appearance of a vehicle display device (800) according to an embodiment of the present invention and a state in which it is mounted on a vehicle (100).

[0240] In this embodiment, the vehicle display device (800) is embedded or built into the dashboard (D) inside the vehicle, and can be configured to pop up upward when necessary so that the transparent display (810) is exposed to the outside.

[0241] Specifically, when the vehicle (100) is in motion or when information display is not required, the transparent display (810) is stored in the lower portion and can be selectively raised to display visual information depending on the vehicle's driving conditions or user settings. This configuration has the advantage of increasing the efficiency of space utilization within the vehicle and minimizing obstruction of the view.

[0242] Additionally, in the example of FIG. 8, the transparent display (810) can be positioned at an angle inclined toward the front windshield, thereby improving readability through visual alignment with the driver's field of vision. This helps to quickly and safely perceive information while driving.

[0243] The transparent display (810) is formed in a structure that can slide or lift in the up-and-down direction, and may include a display driving circuit and an optical filter, a multi-layer glass layer, or a transparent OLED panel inside.

[0244] A shading module (820) is positioned on the back of the transparent display (810) in an integrated or modular manner. The shading module (820) includes a number of microscopic cells or spaces capable of containing fluid within it. Each space is designed to allow fluid to be injected or discharged from the outside, and serves as a functional structure for implementing a selective shading effect.

[0245] The fluid supply unit (830) linked to the shading module (820) may include a euro block including multiple fluid paths, an electronic valve, a pressure pump, a flow control sensor, etc. In this case, an independent control channel may be provided depending on the type of fluid (e.g., transparent fluid, opaque fluid).

[0246] Each of the above components is controlled by a processor (840), and the processor (840) is electrically connected to each component module illustrated in FIG. 9 to independently control the operation and light-blocking state of the transparent display (810) according to various operating situations.

[0247] Through this structure, the vehicle display device (800) of the present invention can effectively provide visual information even in a limited space inside a vehicle, and provides flexibility to actively adjust display exposure and light blocking status according to changes in external illumination or user conditions.

[0248] Fig. 9 is a drawing showing a disassembled form of a part of the internal structure of a vehicle display device (800).

[0249] Referring to FIG. 9, the vehicle display device (800) can be divided into a plurality of modular components, and each component can be designed to be independently assembled and disassembled.

[0250] In FIG. 9, a vehicle display device (800) may include a front cover (801) exposed to the outside, a transparent display (810) positioned at the rear thereof, a middle cover (802) supporting or partitioning the display and the shading module, a shading module array (820), and a back cover (803) positioned at the rearmost end.

[0251] The front cover (801) is formed to harmonize with the interior of the vehicle. The front cover (801) may be configured as a front frame structure that surrounds the exposed portion of a transparent display (810) placed inside when the display is raised or lowered. This front cover (801) can stably support the visible area of ​​the transparent display (810) while also blocking the inflow of unnecessary external foreign substances.

[0252] The above transparent display (810) may be configured with a structure in which one or more display panels, including a cover glass, are laminated. Furthermore, the transparent display (810) is configured to be movable in the vertical direction. This transparent display (810) serves as an area for displaying various driving information or augmented reality (AR) content, and can be driven in various display modes, as illustrated in FIGS. 10 to 34 .

[0253] The above middle cover (802) can serve as a frame that partitions or fixes the transparent display (810) and the shading module array (820) behind it. The middle cover (802) guides each element of the display device to be fixed in place, and allows a space to be formed through which an internal fluid flow path or fluid supply port can pass.

[0254] The above-described shading module (820), i.e., the shading film array, has a structure in which a plurality of shading modules are arranged in an array form, and each module has a structure in which fluid can be selectively injected or discharged therein. The shading modules (820) can be configured independently, and as described in FIGS. 33 to 39, the shading height, shading degree, fluid type, flow rate, etc. can be individually controlled for each area through the processor (840). The shading module (820) is arranged at the rear of the transparent display (810) and serves to adjust the visibility of the displayed content or to correct the visibility for a specific area.

[0255] The above-mentioned back cover (803) is a structure that covers the entire display device from the rear, and functions to ensure durability and protect fluid supply lines, wiring, sensors, etc. from being exposed to the outside. If necessary, a structure for ventilation or heat dissipation may be formed on the back cover (803). In addition, the back cover (803) may be utilized as an area where display driving-related circuits are embedded or combined.

[0256] With this configuration, the vehicle display device (800) includes a transparent display (810) that can be moved up and down, and an independently controllable rear shading module array (820). Thus, it can effectively provide the driver with various visual information depending on the situation, and provide optimized visibility even in various external environments such as high temperatures, strong light, or at night.

[0257] Fig. 10 is a block diagram illustrating the configuration of a vehicle display device (800) according to an embodiment of the present invention. The vehicle display device (800) is configured to automatically determine a driving mode and display conditions based on driving-related information received from a vehicle (100), for example, ADAS (Advanced Driver Assistance Systems) information, and to independently control the position and shading state of a transparent display (810) according to the conditions.

[0258] The vehicle display device (800) includes a transparent display (810), a light-blocking module (820), a fluid supply unit (830), and a processor (840).

[0259] The transparent display (810) may be configured as a TOLED (Transparent OLED)-based display panel and is installed so as to be able to move up and down (pop-up or slide-up / down) from the vehicle dashboard or internal structure according to a control signal from the processor (840). Accordingly, the height of the display exposed to the outside can be adjusted depending on the situation.

[0260] The shading module (820) is placed on the back surface of the transparent display (810) and includes a cell structure having a plurality of fluid inlet spaces therein. Transparent fluids and opaque fluids can be selectively injected into these spaces, and the degree of shading is adjusted depending on the mixing ratio and / or position thereof.

[0261] The fluid supply unit (830) may include a plurality of drive modules (830) and a flow control module (832).

[0262] The drive module (831) serves as a pressure generating means for transporting fluids and may include devices such as an electronic pump, a piezoelectric actuator, or a microactuator. A plurality of these drive modules (831) may be provided, each corresponding to a transparent fluid and an opaque fluid, and are designed to apply different torque or pressure conditions depending on the type of fluid. For example, opaque fluids with high viscosity require higher pressure, in which case a separate high-pressure drive module may be selectively operated.

[0263] The flow control module (832) precisely controls the injection and discharge speed, flow rate, direction, etc. of each fluid. The flow control module (832) may include an electronic valve, a quantitative injection nozzle, a flow sensor, and a feedback control circuit, and controls the fluid flow in real time according to the control of the processor (840). The flow control module (831) may be linked with the driving module (832) to simultaneously or sequentially inject / discharge fluids into different internal spaces of the shading module through multiple paths. In this process, a specific shading effect (such as a wave shape) may be implemented by providing a speed difference or a time difference for each section.

[0264] In addition, the fluid supply unit (830) has a plurality of inlet ports and outlet ports, and each flow path is selectively connected to each compartment area of ​​the shading module (820). In this way, through the cooperative operation of the driving module (831) and the flow control module (832), the type, amount, speed, and timing of the fluid can be comprehensively controlled, thereby precisely controlling the degree of shading and the display state of the transparent display (810).

[0265] The fluid supply unit (830) operates to inject or discharge fluid through each inlet path of the shading module (820) under the control of the processor (840). At this time, transparent fluid and opaque fluid are independently controlled through different channels. The fluid supply unit (830) may include a flow sensor and an electronic valve corresponding to each fluid.

[0266] The processor (840) independently controls the pop-up state (i.e., exposure height according to up-and-down movement) of the transparent display (810) and the fluid state of the shading module (820) according to the control of the fluid supply unit (830). The processor (840) determines a display state suitable for each driving mode based on the vehicle's driving state, external illumination, user input, and / or preset profile information, and controls each component accordingly.

[0267] Figures 11 to 13 are drawings showing the operating states of the vehicle display device (800) in different driving modes.

[0268] Fig. 11 illustrates a first driving mode state (1101). The first driving mode is a non-display or minimum display state, in which the transparent display (810) is maintained in a state in which it is hardly exposed to the outside (low height or non-pop-up state), and at the same time, an opaque fluid exceeding a standard amount is injected into the inside of the light-blocking module (820) to maintain the entire display in a completely light-blocking state. This state can be driven in situations where external display is not required during autonomous driving, conditions in which external information must be minimized, such as when the vehicle is stopped or when the engine is off. The processor (840) suppresses display exposure and maximizes light-blocking under such conditions to reduce visual interference.

[0269] Fig. 12 illustrates a second driving mode state (1102). The second driving mode is an intermediate display state, in which a portion of the transparent display (810) is maintained in a state in which it pops up to the outside (at an intermediate height), and an opaque fluid is injected into the interior of the shading module (820) below a reference level to form a semi-transparent or partially shading state. This state can be utilized to display an augmented reality (AR)-based driving guide, and is suitable when road conditions and content must be recognized simultaneously. The processor (840) adjusts the position and shading level of the transparent display (810) to display content information so that it naturally harmonizes with the external background.

[0270] Figure 13 illustrates a third driving mode state (1103). The third driving mode is a full-screen display or multimedia mode, in which the transparent display (810) pops up to its full length to maintain a high-height state, and the shading module (820) is filled entirely with an opaque fluid to maintain a completely shading state. This state can be maintained when the vehicle is used as a large screen while parked rather than while driving, or when used as an entertainment display device for passengers. The processor (840) maximizes the display area while blocking the inflow of external light, thereby providing an environment optimized for viewing video content, etc.

[0271] In this way, the vehicle display device (800) of the present invention provides a useful effect that can flexibly respond to various driving situations and user needs by independently controlling the position of the transparent display (810) and the degree of light blocking of the light blocking module (820) for each driving mode.

[0272] Fig. 14 is a block diagram showing a fluid inflow and discharge process for shading in a vehicle display device (800) according to an embodiment of the present invention.

[0273] Specifically, FIG. 14 shows details of a fluid circulation path and a sealed structure for controlling the degree of light blocking of a display by injecting or discharging an opaque fluid (e.g., black ink) into a light blocking module (820) formed on the back surface of a transparent display (810).

[0274] The shading module (820) has an internal sealed space defined between the front glass and the back glass, and the interior is configured so that opaque fluid and air can be separately introduced.

[0275] In particular, a conduit for air intake and exhaust may be formed at the upper portion of the shading module (820), and a passage for fluid injection and exhaust may be formed at the lower portion. In addition, a variable space including a rubber tube is provided inside the shading module (820) so as to flexibly respond to pressure changes during fluid injection and exhaust.

[0276] At the lower left of the drawing, a black ink storage tank, a syringe module, and a motor (M) corresponding to a plurality of first driving modules (831a, 831b) of the fluid supply unit (830) are depicted. At the lower right of the drawing, an air injection tank and an associated motor (M) corresponding to a plurality of second driving modules (831c, 831b) of the fluid supply unit (830) are depicted.

[0277] At this time, each reservoir is linked to a syringe-type actuator, and the flow rate is precisely controlled according to the control of the processor (840).

[0278] Specifically, when the fluid moves upward, black ink is injected into the shading module (820) through the lower inlet, and at the same time, external air is sucked in through the conduits on both sides.

[0279] When the fluid moves downward, ink is sucked in and discharged from the same lower inlet, and external air is injected into the sealed space through the conduits on both sides to maintain pressure balance.

[0280] These fluid and air flows have independent flows in the vertical direction, and the view seen through the transparent display (810) is gradually shaded or opened depending on the ink height (column height of the opaque fluid) inside the shade module (820).

[0281] This process is linked to the change in the pop-up height of the transparent display (810), and the processor (840) controls at least one of the fluid outflow speed and flow rate inside the shading module in response to the rising speed of the transparent display (810).

[0282] For example, when switching from the first driving mode (minimum pop-up + maximum shading) to the second driving mode (intermediate pop-up + partial shading), the processor (840) gradually discharges black ink within the shading module (820) in conjunction with the rising motion of the transparent display (810). At this time, the ink discharge speed is adjusted in synchronization with the display pop-up speed.

[0283] Conversely, when returning from the second driving mode to the first driving mode, the processor (840) controls the fluid supply unit (830) to reinject ink from the lower inlet, while simultaneously regulating air to be discharged through the two-sided conduits. This increases the shading height again, returning to the previous black shading state.

[0284] Additionally, the system can operate automatically depending on the vehicle's driving mode. For example, when the vehicle (100) switches from autonomous driving mode to manual driving mode, the processor (840) controls the amount of fluid flow and the display position to automatically return the display exposure height and shading state to the first driving mode. This maximizes the driver's visibility and safety.

[0285] Meanwhile, Fig. 15 illustrates details of the sealed structure of the shading module (820).

[0286] In Fig. 15, an ink passage (826) and an air conduit (827) for fluid flow are arranged in parallel between the front glass (823) and the back glass (823). At the top, a fixing means (821) is vertically connected to a rubber molding (822), which is a fixing support at the bottom, so that durability and sealing are maintained due to repetitive fluid flow. In addition, a hardener (825) may be included between the fixing means (821) and the rubber molding (822) to connect them.

[0287] Such separation of fluid and air flow, independent control method, and precise pop-up operation linkage contribute to securing visual responsiveness in various driving situations and improving user experience, according to the characteristics of the shading module design of the present invention.

[0288] The vehicle display device (800) of the present invention having such a structure includes a transparent display (810), a light-blocking module (820), a fluid supply unit (830), and a processor (840), and is configured to independently control the exposure height and light-blocking degree of the display according to the driver's driving environment.

[0289] The above transparent display (810) is configured to be raised or lowered toward the user's viewing direction, and a shading module (820) having a space into which a fluid can be injected is disposed on the back surface thereof. The shading module adjusts the visibility and shading level as at least one transparent fluid and an opaque fluid are mixed or separately injected.

[0290] The fluid supply unit (830) may include a plurality of flow paths and inlets, and may include two or more fluid storage tanks and flow control modules to independently store and supply transparent fluids and opaque fluids, respectively. These flow control modules include electronic valves, pumps, quantitative injection modules, etc., and precisely control the injection speed and inflow ratio of each fluid under the control of the processor (840).

[0291] The processor (840) can perform the following control according to the switching of the driving mode.

[0292] In the first driving mode (minimum exposure + full shading), the display's exposure height is minimized while the entire internal space of the shading module is filled with an opaque fluid to provide a complete shading state. In the second driving mode (mid-exposure + partial shading), the display is raised to a mid-height and the internal space is injected with a mixed fluid ratio to implement a mixed state of visibility and shading. In the third driving mode (maximum exposure + full transparency or entertainment display), the display is raised to the maximum height and the interior is mainly filled with a transparent fluid to provide visibility suitable for viewing high-resolution images.

[0293] In particular, the fluid supply unit (830) can inject fluid through multiple paths through the first inlet and the second inlet, and by controlling the injection speed or time difference through these inlets, a visual effect such as a wave effect can also be implemented.

[0294] In addition, the processor (840) can control the inflow height of the shading fluid differently depending on the display location of the content within the transparent display (e.g., POI location, text area, etc.), so that an area requiring attention can be controlled to be transparent, and a background or surrounding area can be controlled to be opaque.

[0295] In addition, the device automatically switches the driving mode according to the vehicle start status, driving mode, user settings, external light sensor information, etc., and the fluid injection and discharge speeds are also linked and controlled in response to the rising / falling speed of the transparent display (810).

[0296] Figures 16 to 20 are exemplary drawings explaining an operating scenario of a display device according to an embodiment of the present invention.

[0297] Specifically, FIG. 16 sequentially illustrates the operational changes of the transparent display (810) and the shading module (820) after the vehicle is started, as well as the process of switching the displayed content. In particular, each drawing shows the process of performing visual effects and user-customized interface switching implemented through the control of the inflow and outflow of opaque and transparent fluids.

[0298] Figure 16 illustrates a state (1410) prior to the display popping up immediately after the vehicle is started, in which the entire transparent display (810) remains transparent, allowing the external background to be naturally visible. At this point, the processor (840) recognizes the start signal and prepares to switch to welcome mode to provide a welcome message to the vehicle user.

[0299] In FIG. 17, the transparent display (810) moves upward (DH), and accordingly, the fluid supply unit (830) starts to operate, so that an opaque fluid (e.g., black ink) is gradually introduced from the lower part to the upper part through multiple inlet ports in the shading module (820), thereby varying the shading height (H) (1510). At the same time, the internal air of the shading module (820) is discharged through an air discharge passage in the opposite direction to smoothly induce fluid movement. In addition, the opaque fluid injected at different speeds and pressures through the multiple inlet ports creates a visual effect in the form of a wave from the lower part to the upper part of the transparent display (810), and induces a dynamic screen transition that can focus the user's gaze.

[0300] FIG. 18 illustrates a state (1610) in which the entire screen visible through the transparent display (810) is completely shaded, with the opaque fluid completely filling the internal space of the shading module (820). In this state (1610), customized content such as a user welcome message, a user profile, and a favorite function can be displayed on the front of the transparent display (810), thereby guiding the driver to check key information as soon as he or she gets into the vehicle. At this time, the transparent fluid flows rearward from the internal space, and the opaque fluid can replace the space and block the front view.

[0301] Fig. 19 shows a state (1710) in which the transition to the driving mode begins along with the termination of the welcome mode, in which the opaque fluid flows out through the lower discharge port, and simultaneously, external air is introduced through the air intake paths on both sides, thereby regulating the pressure in the internal space. In addition, the fluid supply unit (830) gradually reduces the opacity of the front surface of the display by reinjecting a certain ratio of the transparent fluid. Accordingly, the shading height (L) for the transparent display (180) is lowered. This control serves to visually and smoothly connect a smooth transition between the welcome mode and the driving mode according to the control algorithm of the processor (840).

[0302] Next, transparency is gradually restored from the bottom of the transparent display (810), exposing the background screen again. Simultaneously, AR-based interface elements, such as vehicle information, destination information, and status information, are displayed through the transparent display (810). In this step, the processor (840) adjusts the inflow ratio and speed of the opaque and transparent fluids, thereby minimizing any visual incongruity perceived by the user and establishing an information focus area.

[0303] Fig. 20 illustrates a final state in which the display is maintained in a segmented state (1810) according to its intended purpose while driving. The lower portion of the transparent display (810) remains light-shielded, and user identification information or basic widgets are displayed. In contrast, the upper portion of the transparent display (810) remains completely transparent and is utilized as a screen for securing an external view or displaying AR content. In particular, AR content with different depths can be displayed on the transparent display (810). This state can be adaptively changed depending on the driving environment, and is implemented through a structure that enables independent control of the light-shielding module (820) for the upper and lower sections of the display area.

[0304] The above series of driving scenarios is based on a dual fluid control mechanism of transparent and opaque fluids, rather than a single fluid injection control. Specifically, the processor (840) comprehensively determines the velocity, inflow volume, location-specific distribution, and pressure status of each fluid, thereby comprehensively controlling the injection order, timing, and even airflow. This control method goes beyond simple light blocking to provide a display environment optimized for user experience, facilitating interface switching according to various driving situations, such as welcome mode, AR driving mode, and media view mode.

[0305] Furthermore, in this embodiment, the display's pop-up height and shade height are independently controlled, enabling customized information display based on the vehicle's driving mode or user interaction. For example, the transparent display can be kept low while implementing an information-intensive mode solely by controlling the shade module. Conversely, visibility can be secured by simply raising the transparent display's position.

[0306] Below, FIGS. 21, 22, 23, and 24 illustrate examples of how shading changes according to driving road conditions and weather environment information during the process of displaying AR content on a transparent display (810).

[0307] The processor (840) of the vehicle display device (800) comprehensively considers the driving status of the vehicle (e.g., stopped, low-speed driving, high-speed driving, autonomous driving, manual driving), external lighting conditions (e.g., night, dusk, presence or absence of streetlights), weather conditions (e.g., clear, rainy, foggy, snowy), surrounding environment (e.g., entering a tunnel, underground parking lot, under a bridge), and user input, and controls the exposure height of the transparent display (810) and the degree of shading of the shading module (820) to be adjusted.

[0308] For example, FIGS. 21 and 22 show screen examples of a transparent display (810) during night driving (FIG. 19A) and rainy weather (FIG. 19B), respectively.

[0309] The processor (840) receives external vehicle information through in-vehicle ADAS sensors, external light sensors, weather sensors, etc., and / or references real-time road and weather information received from a cloud-based server to set a driving mode suitable for the driving conditions. At this time, based on preset profile data according to the driving mode, the exposure height of the transparent display (810) and the degree of light blocking of the light blocking module (820) are adjusted.

[0310] More specifically, when visibility needs to be secured in a night driving condition (1910) as illustrated in FIG. 21 or a rainy driving condition (1920) as illustrated in FIG. 22, the processor (840) controls the injection ratio of the opaque fluid to darken the background (strengthen shading) and enhance the visibility of the AR content. At the same time, the inflow speed and amount of the transparent fluid can be relatively reduced or adjusted to match the inflow of the opaque fluid.

[0311] For example, in weather conditions where visibility is reduced, such as rain or fog, an opaque fluid is partially injected to highlight the preceding vehicle, pedestrian, or road marking as AR graphics, and to partially shade the background.

[0312] Meanwhile, Figures 23 and 24 illustrate a normal driving condition (2010) during the day / night and a complex driving condition (2020) during the city / night, respectively. At this time, the background brightness, AR content density, shading range, and fluid injection method displayed on the transparent display (810) are shown to be differently adjusted. For example, Figure 24 displays various AR contents such as vehicle taillights, guide lines, and route information to the destination, thereby partially shading part or all of the background, thereby improving visibility.

[0313] The processor (840) analyzes ADAS data while the vehicle is in operation to recognize pedestrians, traffic signs, obstacles, etc. on the road ahead, and displays AR graphics highlighting the objects on the display. During this process, opaque fluid can be selectively injected around the location of the recognized object, or transparent fluid can be discharged into the area to enhance contrast.

[0314] In addition, the vehicle display device (800) is configured to be able to communicate with an external server or cloud system, thereby receiving external data such as real-time weather information, traffic congestion, and nighttime streetlight installation information, thereby enabling more sophisticated driving mode switching and fluid control.

[0315] As a result, the vehicle display device of the present invention can dynamically perform fluid-based shading control and AR content display in response to various external environments and driving conditions, thereby maximizing driver visibility and improving driving safety.

[0316] In addition, the processor (840) receives real-time obstacle detection information based on various sensor data provided from the vehicle's ADAS (Advanced Driver Assistance System), and based on this, dynamically performs content displayed on the transparent display (810) and shading control of the shading module (820).

[0317] For example, an object protruding in front of a vehicle, a pedestrian suddenly entering, a fallen object on the road, or an obstacle such as a curb may be detected by the forward radar or camera system of the ADAS. In such a case, the processor (840) may determine the location, size, direction of movement, and possibility of collision of the object, and display the object in the form of an AR graphic such as a caution icon, highlight border, or blinking animation at a corresponding location on the transparent display (810). In this process, an opaque fluid may be selectively injected into the area or its surrounding area to increase the degree of light blocking so that the background of the object can be clearly identified.

[0318] Additionally, if an obstacle exists in a location that requires immediate attention from the driver, the processor (840) can temporarily increase the exposure height of the transparent display (810) or adjust the shading of the display area to secure a focused field of view. In particular, if the background contrast is low even during bright daylight hours, making object identification difficult, the background can be partially shaded to ensure clear recognition of the AR content.

[0319] Furthermore, according to another embodiment of the present invention, the display display can be adjusted based on changes in the vehicle's ground clearance. For example, when the vehicle's ground clearance is raised or lowered by the suspension system during off-road driving, entering a rough road, or entering a speed bump, the processor (840) can recognize the vehicle's ground clearance in real time and change the display mode or driving mode accordingly.

[0320] More specifically, when the vehicle's height is lowered (e.g., high-speed driving mode, tunnel entry), the exposure height of the transparent display (810) is automatically reduced or the degree of light blocking is increased to guide attention information to be focused. Furthermore, when the vehicle's height is raised (e.g., off-road entry, obstacle avoidance situation), the exposure height of the transparent display (810) is expanded and AR content is displayed at a wider field of view, thereby helping to provide overall awareness of the driving environment.

[0321] These features can be implemented in conjunction with the vehicle's ECU and suspension control unit, or an external cloud-based vehicle condition monitoring system, and provide the effect of adaptively switching driving modes without driver intervention and optimizing display content and shading conditions in real time.

[0322] In this way, according to embodiments of the present invention, adaptive display control linked to vehicle dynamic states such as obstacle detection and garage changes is possible, enabling more intuitive and safer driving information to be provided.

[0323] FIG. 25 and FIG. 26 are drawings illustrating examples in which a shading area is variably applied based on the size of image content according to an embodiment of the present invention.

[0324] As illustrated in Figure 25, when the display size of the video content (2110) is relatively small, the content is displayed using only a portion of the transparent display (810). In this case, the remaining area may be filled with an opaque fluid to block light from entering that area. This configuration enhances immersion by blocking external light while simultaneously enhancing focus on the content being viewed.

[0325] On the other hand, as illustrated in FIG. 26, when the display area is expanded to display content (2210), the processor (840) can control the outflow of opaque fluid in response and reduce the light-shielding area to expose the entire screen. In this case, the fluid supply unit (830) controls the outflow speed and amount of opaque fluid to ensure that the image content is provided with good visibility across the entire area of ​​the transparent display (810).

[0326] The above processor (840) determines an active area to which a shading mode is to be applied based on information about the size of the displayed content and the playback mode (e.g., movie, game, etc.), and can control the injection / discharge of an opaque fluid and the up / down movement of the display in conjunction with each other to correspond to the size and position of the active area.

[0327] For example, if content is presented in a vertically tall format, the top and bottom transparent display areas can be expanded while maintaining only the opaque areas on the left and right. Conversely, if the content is wide, the entire central area can be exposed while maintaining a shaded area limited to the bottom or top.

[0328] This content-based shading mode can also be linked to the vehicle's driving status. For example, when the vehicle is in autonomous driving or stopped mode, a relatively large non-shading area for displaying content can be secured. Conversely, when the vehicle switches to driving mode, the content can be quickly reduced or stopped, and a mode for displaying driving information can be switched to displaying driving information by raising the transparent display and injecting shading fluid. In this case, if a change in status is detected while viewing content, the transparent display (810) may first be moved up and down, followed by fluid infusion, to ensure a smooth transition from shading mode to transparent mode.

[0329] Figure 27 illustrates an example of a display mode (2310) that provides AR content in response to a point of interest (POI) detected while driving, according to an embodiment of the present invention. For example, when a vehicle passes near a promotional area of ​​a specific store, the processor (840) generates AR content based on the vehicle's location data and POI information, and visually displays the information in a non-shaded area of ​​a transparent display (810). At this time, to increase user concentration, shading may be applied to a portion of the background, allowing the content to be more clearly visible.

[0330] Below, FIG. 28 is a drawing showing an example (2410) of information types according to display positions in each display mode according to an embodiment of the present invention.

[0331] The above transparent display (810) can be divided into an upper region (e.g., driving guidance information display section) (2411) and a lower region (e.g., driving status information display section) (2412) to display information. This division can be configured to provide different light blocking for each region. Thus, the speed and amount of light blocking fluid flowing between the upper and lower regions can be independently controlled depending on changes in the vehicle's driving status or the type of content being displayed.

[0332] The processor (840) may set at least one of the upper and lower areas of the transparent display (810) as a light-shielding area, and may display AR-based content or guide information by overlaying it on the remaining areas. At this time, in order to prevent the user's field of vision from being uncomfortable due to a sharp difference in the amount of light between the light-shielding area and the non-light-shielding area, the processor (840) may adjust the amount of light of the transparent display (810) differently for each area.

[0333] For example, a relatively high voltage or current is applied to a non-shaded area to make it appear brighter, and a lower voltage or current is applied to a shaded area to control the amount of light so that it is naturally harmonized.

[0334] FIG. 29 is a block diagram illustrating a process in which a display mode is determined based on vehicle data according to an embodiment of the present invention, and the degree of shading and the operation of a transparent display are linked and controlled accordingly.

[0335] The above vehicle display device (800) is configured to selectively switch display modes based on the vehicle's status, surrounding environment information, and user operations. Data / signals corresponding to various inputs from the vehicle's microphone, camera, touch interface, driving information, interior information, and vehicle sensors are transmitted to the processor (840), and the processor (840) determines an appropriate display mode and degree of shading based on the data.

[0336] The above processor (840) can control to automatically switch to a first driving mode (e.g., minimum display height and shading release state) when the vehicle switches from autonomous driving mode or stopped state to manual driving mode, or when an ignition off signal of the vehicle is detected.

[0337] Additionally, when the vehicle is stopped or parked, the transparent display (810) can be switched to a full light-blocking state and can operate to enable viewing of content or entry into a specific user mode.

[0338] Such vehicle condition-based control is performed in conjunction with a fluid supply unit (830). The fluid supply unit (830) includes a first flow control unit (for opaque fluid) and a second flow control unit (for transparent fluid), each of which can supply or retrieve fluid through a flow path independently connected to the internal space of the shading module (820). The opaque fluid and the transparent fluid have different specific gravities, and each flow control unit is designed to operate independently according to such fluid characteristics.

[0339] The first flow control unit and the second flow control unit each include a first driving module and a second driving module. In this case, each corresponding driving module may include an electronic valve, a pressure pump, and / or a quantitative injection module. The processor (840) can precisely control the inflow and outflow speeds of the opaque fluid and the transparent fluid by applying different torques or driving pressures to each driving module, and dynamically adjust the mixing ratio of the fluids within the internal space of the shading module (820).

[0340] In addition, the display module includes a shader as a shading module (820) and a display actuator for vertical movement of the transparent display (810). In addition, vertical movement of the transparent display (810), supply / discharge of shading fluid, and light quantity correction are performed in real time under the control of the processor (840). This enables fluid screen control that satisfies both user experience and driving safety.

[0341] That is, the vehicle display device (800) of the present invention can automatically switch the display mode according to input information (e.g., vehicle status, surrounding sensor data, etc.), and provide appropriate visibility and immersion by adjusting the height of the transparent display and inflow / outflow of light-blocking fluid in conjunction therewith. In particular, precise control is possible through independent flow control according to the type of fluid and linkage with the electronic drive system, which enables implementation of an adaptive display capable of responding to various vehicle driving situations.

[0342] The first drive module (for opaque fluid) and the second drive module (for transparent fluid) included in the fluid supply unit (830) are configured to set different drive conditions according to the characteristics of fluids having different viscosities and specific gravities. Accordingly, the processor (840) can efficiently control the fluid inflow speed in various operation scenarios based on the threshold of the reference torque or drive pressure corresponding to each fluid.

[0343] For example, the opaque fluid controlled by the first drive module has high viscosity characteristics and generally requires relatively high drive torque (T₁) or drive pressure (P₁). At this time, the processor (840) can be set to initiate the inflow only when a reference torque T₁ or reference pressure P₁ or higher is applied to control the inflow of the opaque fluid.

[0344] Example 1 (opaque fluid, above reference value)

[0345] When the vehicle is stopped and the user switches to the movie content viewing mode, the processor (840) applies a control signal of a reference torque T₁ or higher or a reference pressure P₁ or higher to the first driving module to expand the shading area and increase the sense of immersion. Accordingly, a large amount of opaque fluid is injected and evenly distributed in the internal space of the shading module (820) arranged at the rear of the transparent display (810), and the front shading mode is quickly formed.

[0346] Example 2 (opaque fluid, below standard)

[0347] On the other hand, when the vehicle switches to manual driving mode or AR driving guidance mode, the processor (840) controls the discharge or blocking of the inflow of the opaque fluid to secure visibility. At this time, only a signal less than the reference torque T₁ or less than the reference pressure P₁ is applied to the first driving module, so that the opaque fluid in the shading module is not inflowed and only the discharge operation is performed, thereby maintaining the transparent state.

[0348] Example 3 (transparent fluid, above standard value)

[0349] The transparent fluid has relatively low viscosity and can be rapidly introduced or discharged even under low torque or pressure conditions. Using this, in order to clearly transmit information when the vehicle is driving at high speed at night and the external illumination is low, the processor (840) applies a signal greater than or equal to the reference torque T₂ or the reference pressure P₂ to the second driving module to rapidly inject the transparent fluid. Accordingly, the remaining opaque fluid within the shading module is pushed out, and the transparent state of the transparent display (810) is maintained, thereby ensuring visibility.

[0350] Example 4 (transparent fluid, below standard)

[0351] Additionally, when the vehicle needs to remain in shading mode while stationary, the second drive module is supplied with a control signal below the threshold (T₂, P₂), thereby suppressing the inflow of transparent fluid. This maintains the opaque fluid within the shading module, blocking the inflow of external light, and providing an environment optimized for viewing video content.

[0352] In this way, the fluid supply unit according to the present invention can precisely control two types of fluids (opaque and transparent) with different characteristics by utilizing different reference torques or driving pressures. Furthermore, the visibility and immersion of the transparent display (810) can be flexibly adjusted according to the vehicle's driving mode and user settings. This control is achieved by precisely controlling the inflow / outflow speed and amount of fluid using electronic valves, pressure pumps, and quantitative injection modules.

[0353] Figures 30, 31 and 32 illustrate examples of implementing a visual wave effect by controlling the injection speed and inflow path of different fluids according to an embodiment of the present invention.

[0354] The shading module (820) of the transparent display (810) is formed with a structure in which an opaque fluid is injected or discharged through a plurality of channels, and the visual effects of the display device can be diversified by controlling the inflow speed, direction, and timing of the fluid.

[0355] Figure 30 shows a driving scenario (2610) in which opaque fluid is first introduced through specific inlets (e.g., left ①, right ③) and the remaining inlets (e.g., left ②, right ④) discharge the fluid. In this case, shading occurs starting from the area where the fluid is first introduced, and a curved boundary is formed according to the direction of the fluid flow. This provides the viewer with a visual effect of wave-like shading changes, i.e., a 'wave'.

[0356] Figure 31 illustrates a reverse driving scenario (2620). Here, the combination of injection and discharge is varied, and a "reverse wave" effect is implemented, where the boundary line at the top or bottom of the screen bends differently depending on the difference in fluid flow direction and speed. This allows users viewing the display from inside a vehicle to experience a richer and more dynamic visual experience.

[0357] These visual effects can be designed to provide a natural transition in the display environment when switching between driving modes or entering specific content modes (e.g., movie mode, game mode, etc.).

[0358] To this end, the fluid supply unit (830) includes a first inlet connected to the first flow path and a second inlet connected to the second flow path, and is designed to independently control the flow rate and start time of the fluid flowing in through each flow path. The processor (840) can individually control the opening time or pump pressure of the injection valve corresponding to each flow path, thereby differently controlling the inflow rate and amount of the fluid. For example, by first opening the valve of the first inlet and then opening the second inlet after a predetermined time delay, a time-difference-based asymmetric inflow is possible.

[0359] Figure 32 illustrates a structure for explaining various waveform shading effects that can be implemented through this configuration. It demonstrates that various types of curved shading boundaries can be formed by creating an asymmetrical flow to the left or right by controlling the inflow / outflow ratio or speed of different fluids. For example, a waveform shading effect can be provided by reducing the specific gravity of the transparent fluid flowing upward in the upper region (2710) and increasing the specific gravity of the opaque fluid flowing downward in the lower region (2720).

[0360] This implementation overcomes the limitation of typical liquid flow, where the wave effect is confined only around the inlet due to the pressure effect at the initial fluid inflow.

[0361] The processor (840) can independently drive the motor and control board corresponding to each fluid tank to implement a continuous wave effect. At this time, the liquid inflow / outflow pattern can be set in a manner such as '① inflow - ② outflow - ③ inflow - ④ outflow' or '① outflow - ② inflow - ③ outflow - ④ inflow', and this combination greatly improves the visual transition feeling when switching modes.

[0362] Additionally, it is possible to increase the number of channels for each fluid to increase the number of waves. In this case, additional development tanks and corresponding control modules can be provided connected to each channel. This provides various visual effects depending on the type of content, vehicle status, or user preferences, contributing to the enhanced immersion and user experience of the present invention.

[0363] Meanwhile, although not shown in the drawing, according to another embodiment of the present invention, the wave effect can be implemented in a form that starts from the central area of ​​the display and spreads in both left and right directions.

[0364] To this end, the fluid supply unit (830) may be designed to have first and second inlets corresponding to the central position among the plurality of paths connected to the shading module (820) of the transparent display (810), and fluid may flow in both directions from these inlets.

[0365] The processor (840) can first initiate the operation of a valve or pump connected to the central inlet, and then adjust each driving pressure and valve opening time so that fluid is sequentially moved to the left and right direction paths.

[0366] For example, by first injecting opaque fluid through inlets ② and ③ located at the bottom center of the display, and then configuring it to additionally inject fluid through the left inlet ① and the right inlet ④ after a certain period of time, a wave shape is implemented in which the shading effect spreads left and right based on the center of the screen.

[0367] These centrally initiated wave effects can be utilized to maximize visual attention during vehicle operation, aligning with special content (e.g., driving information focus mode, vehicle sensing notification visualization, driving mode switching, etc.) or custom events. Because the changes begin in the central area, where the driver's gaze primarily lingers, they are highly effective in enhancing the perception of mode switching and enhancing visual immersion.

[0368] Additionally, since the fluid flow starting from the center maintains symmetry and spreads out, it provides a sense of visual unity in large displays with multiple flow paths, and by precisely adjusting the flow rate control for each inlet, waveform effects with various amplitudes and periods can also be implemented.

[0369] These embodiments provide a technical effect that can simultaneously satisfy visual responsiveness and user attention guidance while improving the emotional quality of a vehicle display system.

[0370] FIG. 33 and FIG. 34 are drawings illustrating a configuration and fluid flow in which a rectangular transparent display (810) within a vehicle display device is divided into a plurality of display areas and the degree of light blocking of a plurality of light blocking areas corresponding to each display area is independently controlled, according to an embodiment of the present invention.

[0371] A vehicle display device (800) includes a rectangular transparent display (810), and the transparent display (810) is formed to be long in a horizontal direction and includes a plurality of display areas functionally divided into a first display area, a second display area, a third display area, etc.

[0372] Each of these display areas is configured to independently display screen information without mutual interference. For example, the first display area may correspond to vehicle cluster information, the second display area may correspond to central infotainment (CID) information, and the third display area may correspond to head-up display (HUD) information.

[0373] A shading module (820) is arranged at the rear of the transparent display (810), and the shading module (820) includes a first shading area, a second shading area, and a third shading area corresponding to each display area, and each shading area is physically partitioned by a transparent partition to prevent fluids from mixing with each other. In addition, each shading area is provided with an independent fluid inlet and outlet, so that fluid can be independently injected or discharged from a fluid supply unit (830).

[0374] At this time, the fluid supply unit (830) includes an independent motor and control system corresponding to each shading area, and is provided with a control valve that adjusts the flow rates of transparent fluid and opaque fluid, respectively, so that the fluid injection or discharge speed can be individually controlled for each of the multiple shading areas. Accordingly, even under the same display mode, it is possible to control the height of the opaque fluid injected into each shading area to be maintained differently or the same.

[0375] FIG. 33 is a drawing illustrating an example of a vehicle display device according to one embodiment of the present invention, in which a light-blocking module of a transparent display (810) is divided into a plurality of independent light-blocking areas, and fluid is separated and injected and discharged.

[0376] As illustrated in the drawing, the shading module of the display (810) is internally divided into Area A and Area B. Each area is designed so that the degree of shading can be independently adjusted depending on the type and amount of fluid flowing into the area. This division structure is advantageous in implementing different visibility environments for multiple content areas while minimizing fluid interference between the areas.

[0377] Each shading area (A, B) is supplied with fluid through a different path, with path a being connected to area A and path b being connected to area B. Each path is individually controlled by a corresponding drive motor and control board, thereby enabling independent operation of the a inflow and a outflow. Meanwhile, the b fluid can be controlled to prevent inflow or outflow at a specific point in time by being forcibly locked according to the settings.

[0378] Additionally, each of the above-mentioned areas is internally divided by transparent partitions and support structures. This prevents the boundaries from collapsing due to fluid pressure or movement. In particular, the lower area of ​​the bezel is provided with an auxiliary fluid flow path connecting the two shaded areas (A and B), allowing the liquid to move to other areas under certain operating conditions.

[0379] For example, when fluid A flows into area A and rises, fluid B can naturally move toward area B through the connecting passage at the bottom of the split support structure due to the resulting change in internal pressure. At this time, the movement of fluid B is performed in the form of a passive reaction without a separate motor operation, and the volume balance of the fluid is maintained through the passage. Accordingly, the control system can efficiently change the shading state between the split areas simply by the inflow / outflow of the liquid.

[0380] In this way, fluid injection into each shading area is individually driven by a corresponding motor and flow control system. Furthermore, the split support structure can be movably driven, if necessary, to expand the fluid flow path. This structural combination enables flexible and precise shading implementation for complex content information structures.

[0381] Additionally, the entire system calculates the volume of inflow / outflow fluid based on the rotational speed of the drive motor or the flow sensor, enabling quantitative control. Accordingly, the shading effect of each area can be optimized based on the type, location, and brightness level of each content displayed on the transparent display (810).

[0382] For the region, the b fluid can be set to move as a reaction flow according to the injection or discharge of the a fluid (transparent fluid), rather than as a forced drive.

[0383] FIG. 34 is a drawing illustrating an example of precisely controlling fluid for a plurality of light-shielding areas in a vehicle display device according to one embodiment of the present invention.

[0384] As illustrated in the drawing, the transparent display (810) may be divided into a cluster region (L) on the left and a CID or PID region (R) on the right. Each of these regions is composed of an independent shading module and may have different sizes. For example, the R region may have a relatively narrower or wider area than the L region.

[0385] Each shading module has a separate flow path through which an opaque fluid flows, and a control valve capable of precise flow control is installed at the inlet of the flow path. This control valve may correspond to a first drive module (831(A)) for supplying an opaque fluid or a second drive module (831(I)) for supplying a transparent fluid among a plurality of drive modules (831) included in a fluid supply unit (830). These drive modules adjust the flow rate of the fluid flowing into each shading area in real time, and the processor (840) controls these flow rates based on the vehicle driving mode, driving environment, user settings, etc.

[0386] In particular, when multiple shaded areas have different areas, the final height of the fluid within each area must be maintained identically to maintain visual consistency in a single driving mode. To this end, the processor (840) quantitatively controls the fluid inflow rate and total inflow amount to ensure the same height by considering the area information of each area. For example, a larger area, L, requires more fluid to be injected per unit time, and accordingly, a valve with a relatively large opening or a high-pressure pump may be operated in the inflow path of L.

[0387] This precise control plays a crucial role in ensuring a sense of unity between the displayed content and the visual shading effect when multiple contents are simultaneously displayed across multiple shading areas, or when a single content extends across multiple areas. Furthermore, the flow of fluid may be affected by changes in the shape or viscosity of the fluid within the shading area, and accordingly, the processor (840) is configured to finely adjust the flow rate through real-time sensor feedback.

[0388] Consequently, the embodiment illustrated in FIG. 34 presents a structure and operating method for precisely controlling the inflow of shading fluid based on a control valve and drive module so as to maintain overall visual consistency and content readability even when multiple display / shading areas exist.

[0389] This configuration has the advantage of being able to independently provide various information (e.g., cluster, CID, HUD, etc.) in each display area on a single vehicle display, while independently implementing the necessary shading effect for each area to improve the visibility and readability of the information.

[0390] Figures 35 and 36 are drawings for explaining a shading area division structure and fluid injection / outflow flow for each area according to one embodiment of the present invention.

[0391] The vehicle display device includes a single rectangular transparent display (810). This transparent display is divided into multiple display areas according to function. For example, the first display area may correspond to a cluster, the second display area may correspond to a CID (Center Information Display), and the third display area may correspond to a PID (Passenger Information Display).

[0392] A corresponding shading area is provided behind each of these display areas. Each shading area is partitioned by a transparent partition. Accordingly, the first shading area (L), the second shading area (C), and the third shading area (R) are formed independently of each other.

[0393] Transparent and opaque fluids can be selectively injected into each shading area. The transparent fluid is supplied from the upper transparent fluid tank (831(A)), and the opaque fluid is supplied from the lower opaque fluid tank (831(I)). The fluids are supplied through fluid inlets for each area, and each of these inlets is equipped with control valves (832a, 832b, 832c) for controlling the flow rate.

[0394] The processor (840) controls the type of fluid, injection speed, injection time, etc. for each area according to the display mode of the display. For example, in cases where only some areas require shading, such as in AR mode, opaque fluid is injected only into the shading film of the area, and the remaining areas maintain transparent fluid.

[0395] Additionally, the height of the fluid within the shading film is adjusted according to the pop-up operation of the transparent display (810). For example, referring to FIG. 36, when the display is raised from a state of full shading in simple mode to an AR mode (3110), the opaque fluid is controlled to remain in the remaining areas except for the area where AR content is to be displayed. At this time, the amount of fluid flowing out is adjusted to correspond to the rising height of the display. That is, the shading height is maintained by adjusting the flow rate or flow time.

[0396] Each divided shading area can be separated from the others by a sealing structure that interlocks with the bezel structure. This sealing structure prevents fluid leakage and allows independent fluid injection into each area. A passageway is formed at the bottom of the structure to allow fluid flow, allowing fluid to move naturally according to specific gravity differences.

[0397] In particular, the fluid inflow into each shading area is controlled by controlling one or more of the inlet diameter, inflow rate, or inflow time. This allows for different shading levels and visual effects (e.g., wave effects) to be implemented for each area.

[0398] Additionally, by sequentially controlling the fluid inflow pattern over time, a visual ripple effect can be created on the display. This provides users with an intuitive and immersive visual transition experience when switching displays.

[0399] As a result, the display device according to the present embodiment can independently control the shading of multiple areas partitioned within one panel, and each area can provide a display environment optimized for a different display function (CID, PID, Cluster, etc.).

[0400] Additionally, according to one embodiment of the present invention, the size of each shading area can be varied in the longitudinal (vertical) direction and / or the transverse (horizontal) direction.

[0401] Since each shading area may require different shading areas depending on its location within the display and the type of displayed content, the shape or range of the area can be dynamically adjusted to adapt to this.

[0402] The longitudinal variation is primarily linked to the display's pop-up or lowering height. For example, when the display is fully raised in a certain mode, the opaque fluid within the shade is injected to a height corresponding to the entire display area. Conversely, when the display is only partially raised or lowered, the shade's shading height is controlled to decrease accordingly.

[0403] Horizontal variability is implemented by varying the horizontal extent of each shaded area based on the display mode or user selection. For example, when content is concentrated in the secondary display area (CID), the horizontal width of the secondary shaded area can be expanded to include portions of the adjacent area. This horizontal expansion is induced by adjusting the transparent partition or movable sealing structure, or by adjusting the control timing of multiple liquid inlets.

[0404] These longitudinal and lateral variable functions are linked to a split support structure built into the sunshade. The structure's split position can be adjusted by mechanical lead screw drive or an electronic control system. This allows the shape and size of the shade area to be flexibly adjusted based on user experience and vehicle driving mode, providing both visual immersion and functional efficiency.

[0405] In this way, the present invention provides a technical advantage that can flexibly respond to various display modes and user needs by fluidly controlling multiple shading areas in the longitudinal and transverse directions within a single rectangular display.

[0406] FIG. 37, FIG. 38, and FIG. 39 are drawings illustrating examples of variably controlling a plurality of light-shielding areas in a longitudinal or transverse direction in a vehicle display device (800) according to one embodiment of the present invention.

[0407] A vehicle display device (800) includes a transparent display (810) and a shading module (820) positioned at the rear thereof. The shading module (820) is divided into a plurality of independent shading areas, each corresponding to a first display area, a second display area, and a third display area. Each area can be mapped to a functional area such as a cluster, a central display (CID), and a secondary display (PID).

[0408] A partition structure is provided within the shading module (820). This partition structure forms multiple fluid compartment spaces, each configured to induce different fluid flows. Each compartment may have similar or different sizes, and the amount of fluid it can accommodate varies accordingly.

[0409] The fluid supply unit (830) comprises a plurality of independent fluid channels corresponding to the partition structure. These channels are configured to individually inject or discharge transparent or opaque fluid into each shading area. At this time, the amount of fluid flowing into each area is precisely controlled by controlling at least one of the diameter of the inlet, the inflow rate, and the inflow time.

[0410] The processor (840) controls the fluid flow in each shading area in the following manner:

[0411] When the display mode is changed, the amount of fluid discharged is adjusted so that the opaque fluid height of each shaded area remains the same as before.

[0412] After the display pop-up is complete, the display state is maintained consistently by adjusting the fluid flow rate in response to the increased height.

[0413] To achieve the same shading height even when the sizes of each shading area are different, the processor controls the amount of fluid injected differently for each area.

[0414] Conversely, even areas of the same size can be controlled to have different fluid heights in different display modes.

[0415] The shading area (820) can change its shading in the longitudinal (vertical) direction (3210) according to the aforementioned operation as illustrated in FIG. 37. In addition, the shading area can change its shading in the transverse (horizontal) direction (3310) according to the aforementioned operation as illustrated in FIG. 38.

[0416] Figure 39 illustrates an example of simultaneous vertical and horizontal shading changes (3410). These changes are dynamically implemented through fluid injection position, velocity, and flow rate control according to the aforementioned operations.

[0417] Additionally, the device can operate multiple display modes simultaneously within a single display. For example, AR mode can be simultaneously executed in a first area, and media content mode in a third area. In this case, the pop-up height of the entire display is the same, but fluid control is performed independently in each shaded area.

[0418] The fluid supply unit (830) can be linked to an external light sensor. In this case, visibility is ensured by automatically adjusting the degree of shading based on the external brightness. Furthermore, the shading status of specific areas can be changed based on manual input from the user.

[0419] Shading control can be synchronized with the display's elevation speed. For example, if the display's elevation speed is fast, fluid inflow must also be performed quickly accordingly. The processor (840) takes this into account and adjusts the fluid flow to each shading module in real time.

[0420] Through this configuration, the vehicle display device of the present invention can independently adjust multiple shaded areas, enabling flexible shade control to expand or contract vertically or horizontally. This contributes to improved user visibility, content concentration, and environmental adaptability.

[0421] Meanwhile, although not disclosed in the drawings, according to another embodiment of the present invention, the shading state can be automatically adjusted based on the vehicle's internal temperature or the external temperature. For example, if the vehicle's temperature sensor determines that the internal temperature rises above a preset threshold, the processor can inject a certain percentage or more of an opaque fluid into the internal space of the shading module to maintain the overall shading state, thereby enhancing the sunlight blocking effect. This automatic shading can be applied even when the vehicle is stopped or parked, and can provide the effect of preventing the temperature inside the vehicle from rising before boarding.

[0422] Furthermore, according to another embodiment of the present invention, the degree of shading or the display height of the display can be automatically controlled based on road environment information received from a front camera or navigation system installed in the vehicle. For example, when the vehicle enters a highway driving state, the processor can raise the transparent display to a full exposure state and adjust the injection ratio of the opaque fluid included in the shading module to prevent diffuse reflection of external sunlight. On the other hand, in an urban driving state, the display can be kept partially exposed while maintaining a transparent area for AR guide display. In this way, the degree of shading and the display height can be automatically adjusted depending on the driving environment.

[0423] Furthermore, according to another embodiment of the present invention, the degree of shading or brightness of the display can be automatically adjusted depending on the day / night time zone. For example, if the processor recognizes that the current time is nighttime through the vehicle's system clock or GPS, it can control the display area of ​​the transparent display to lower the shading state and increase the brightness of the content. Conversely, during the day, an opaque fluid can be injected into the internal space of the shading module to prevent sunlight reflection, thereby maintaining overall visibility. This method provides the effect of optimizing the display field of view according to the changing time zone without separate driver operation.

[0424] As described above, the vehicle display device according to an embodiment of the present invention can independently control the exposure height and degree of light blocking of the transparent display, thereby flexibly implementing various display environments depending on the driver, driving conditions, and / or system settings. Furthermore, since the position and intensity of the light blocking can be finely adjusted depending on the type of fluid, inflow / outflow speed, and inflow path, more suitable visibility and immersion can be provided depending on the external illumination or content type. Furthermore, since the optimized display state according to the situation can be maintained without user operation through automatic control linked to vehicle data such as the vehicle's driving condition, autonomous driving status, stop detection, and engine status, both safety and convenience are improved. Furthermore, by independently controlling multiple light blocking modules or light blocking areas, it is possible to implement a user experience-based display that can display information separately by upper / lower or left / right areas, or emphasize AR content without obstructing driving or vision.

[0425] The present invention described above can be implemented as computer-readable code (or application or software) on a program-recorded medium. The above-described method for controlling an autonomous vehicle can be realized by code stored in memory or the like.

[0426] A computer-readable medium includes any type of recording device that stores data that can be read by a computer system.
