[0047] Additionally, the bezel portion can secure the front glass and rear glass and shield the sealing member.

[0048] Additionally, the first fluid and the second fluid can flow quickly by the front water-repellent treatment layer and the rear water-repellent treatment layer.

[0049] Additionally, when the variable storage is compressed or expanded, the first fluid or second fluid contained in the variable storage can quickly flow into the inner space.

[0050] Additionally, the first fluid and the second fluid can be simultaneously flowed by one driving source.

[0051] In addition, the first storage unit includes a barrier that divides a first space in which a first fluid is accommodated and a second space in which the first fluid is accommodated, and can disperse the first fluid and cause it to flow into a shading cell, and can form an interface between the first fluid and the second fluid in a curved shape, and can be further improved.

[0215] The first fluid passage (94) can be connected to the inner space (S1) and the first storage (10), respectively.

[0216] The first fluid passage (94) can be connected to the inner space (S1) through the first inlet / outlet section (91).

[0217] A plurality of first fluid passages (94) may be provided, and a plurality of first inlet / outlet sections (91) may be provided to correspond to a plurality of first fluid passages (94).

[0218] A pair of first inlet / outlet portions (91) may be formed in the sealing member (9). The pair of first inlet / outlet portions (91) may be spaced apart in the left-right direction (Y).

[0219] When a pair of inlet / outlet ports (91) are formed in the sealing member (9), the display device may be provided with a pair of first fluid passages (94).

[0220] The first inlet / outlet section (91) and the first fluid passage (94) can correspond 1:1.

[0221] The second fluid passage (96) can be connected to the inner space (S1) and the second storage (11), respectively.

[0222] The second fluid passage (96) can be connected to the inner space (S1) through the second inlet / outlet section (92).

[0223] A plurality of second fluid passages (96) may be provided, and a plurality of second inlet / outlet sections (92) may be provided to correspond to a plurality of second fluid passages (96).

[0224] A pair of second inlet / outlet sections (92) may be formed in the sealing member (9). The pair of second inlet / outlet sections (92) may be spaced apart in the left-right direction (Y).

[0225] When a pair of second inlet / outlet sections (92) are formed in the sealing member (9), the display device may be provided with a pair of second fluid passages (96).

[0226] The second inlet / outlet (92) and the second fluid passage (96) can correspond 1:1.

[0227] For example, a single first reservoir (10) may be provided, and a first fluid (5) contained in the first reservoir (10) may be branched into a plurality of first fluid passages (94) and moved to the inner space (S1) through the plurality of first fluid passages (94). In addition, a single second reservoir (11) may be provided, and a second fluid (6) contained in the second reservoir (11) may be branched into a plurality of second fluid passages (96) and moved to the inner space through the plurality of second fluid passages (96).

[0228] As another example, a plurality of first reservoirs (10) and first fluid passages (94) may be provided, and a plurality of second reservoirs (11) and second fluid passages (96) may be provided.

[0229] In this case, the first fluid (5) contained in any one of the plurality of first reservoirs (10) can be moved to the inner space (S1) through any one of the plurality of first fluid passages (94), and the first fluid (5) contained in another one of the plurality of first reservoirs (10) can be moved to the inner space (S1) through any one of the plurality of first fluid passages (94). In addition, the second fluid (6) contained in any one of the plurality of second reservoirs (11) can be moved to the inner space (S1) through any one of the plurality of second fluid passages (96), and the second fluid (6) contained in another one of the plurality of second reservoirs (11) can be moved to the inner space (S1) through any one of the plurality of second fluid passages (96).

[0230] Among the first fluid (5) and the second fluid (6), the fluid with a higher specific gravity can flow in from the lower part of the inner space (S1) or flow out from the lower part of the inner space (S1).

[0231] Among the first fluid (5) and the second fluid (6), the fluid with a lower specific gravity can flow into the upper part of the inner space (S1) or flow out from the upper part of the inner space (S1).

[0232] The upper part of the first inlet / outlet section (91) may be closer to the lower part among the upper and lower parts of the shading cell (4).

[0233] The upper part of the second inlet / outlet (92) may be closer to the upper part among the upper and lower parts of the shading cell (4).

[0234] When the first fluid (5) contained in the first reservoir (10) flows into the inner space (S1) through the first fluid passage (94) and the first inlet / outlet (91), the second fluid (6) contained in the inner space (S1) can move to the second reservoir (11) through the second inlet / outlet (92) and the second fluid passage (96).

[0235] Conversely, when the second fluid (6) contained in the second reservoir (11) flows into the inner space (S1) through the second fluid passage (96) and the second inlet / outlet (92), the first fluid (5) contained in the inner space (S1) can move to the first reservoir (10) through the first inlet / outlet (91) and the first fluid passage (94).

[0236] The first storage unit (10) and the liquid tank drive unit (13), the first fluid passage (94) and the first inlet / outlet unit (91) may be provided as a pair, and the second storage unit (11) and the air tank drive unit (14), the second fluid passage (96) and the second inlet / outlet unit (92) may be provided as a pair.

[0237] The display device may further include a pair of liquid tank driving units (13), a pair of air tank driving units (14), and a controller (not shown) for controlling the lifter.

[0238] The controller can control a pair of liquid tank drive units (13), a pair of air tank drive units (14), and a lifter according to the surrounding conditions of the vehicle, the surrounding conditions of the vehicle, and the commands of the passengers.

[0239] The display device can minimize consumer perception of delays in the transition between transparency and opacity by linking the liquid's movement speed with the display's driving speed.

[0240] The controller can connect the control of a pair of liquid tank driving units (13), a pair of air tank driving units (14), and a lifter by considering the movement distance of the first fluid (5) or the second fluid (6), the change in volume within the first reservoir (10) or the second reservoir (11), etc.

[0241] Initially, the shading cell (4) of the display device may be transparent, and later, the shading cell (4) may be opaque.

[0242] When the transparent display (3) is driven, the ratio of the transparent area containing the second fluid and the opaque area containing the first fluid can be adjusted.

[0243] When the vehicle is started or the display device is initially operated, a first fluid may be filled in the transparent area, and the transparent display (3) may display an initial screen and driver information.

[0244] Thereafter, as the first fluid (5) descends from the inner space (S1), the second fluid (6) can fill the inner space (S2), and information related to vehicle driving can be displayed in the transparent area, and menus, etc. can be displayed. The transparent area can be used in various modes.

[0245] After the vehicle is driven, the transparent area can operate in AR driving mode.

[0246] When driving a vehicle, transparency can be adjusted and object AR graphics can be displayed to ensure visibility according to the surrounding conditions.

[0247] To ensure visibility in rainy, foggy, or other weather conditions, AR graphics can be displayed in a transparent area to other vehicles on the road. In these cases, a partial shading mode can be applied to the background.

[0248] Through sensors such as ADAS, non-vehicle objects can be displayed in transparent areas as AR graphics on deserted roads without streetlights.

[0249] Even during bright daylight, if an obstacle is suddenly detected, a notification can be displayed in the transparent area as an AR graphic around the obstacle.

[0250] The vehicle can be implemented as a shading mode for viewing content when the vehicle is stopped, stopped, or driving autonomously.

[0251] The transparent and opaque areas can be separated, or an optional use environment can be provided in which full opacity can be used, in which case the left and right liquid inflows can be separated and introduced.

[0252] Depending on the vehicle's driving conditions, it can be used in a transparent area lowered state or in AR mode.

[0253] When viewing content while the vehicle is stopped or stationary, the height of the opaque area may be adjusted to display the content according to the appropriate magnification.

[0254] By exposing the front of the active area (shading mode) when driving the active area up and down, you can maximize the experience of viewing content in proportion to movies, games, etc.

[0255] While the content is being displayed, the active area can be moved up and down proportionally.

[0256] Depending on the magnification appropriate to the content, the liquid shading film on the left / right / left / right of the active area can be displayed separately, and the operation for adjusting the magnification can be performed seamlessly by taking into account the liquid inflow time.

[0257] Even while viewing content, the active area can move up and down, switching from shading mode to transparent mode, based on the vehicle's driving conditions (e.g., increasing driving speed, switching driving modes). Since the transition to transparent mode takes some time, the vertical movement may be performed first, depending on the driving conditions.

[0259] The display device may further include a front glass (8) and a bezel portion (9c) that secures the rear glass (8).

[0479] The fifth example of the display device can make the stroke of the first pressure plate (23c) and the stroke of the second pressure plate (23f) the same by one two-axis motor (22a).

[0480] In this case, the flow rate of the first fluid (5) flowing out from the first reservoir (19) may be the same as the flow rate of the second fluid (6) flowing into the second reservoir (20), and the flow rate of the first fluid (5) flowing into the first reservoir (19) may be the same as the flow rate of the second fluid (6) flowing out from the second reservoir (20).
