[0001] The present invention relates to a display device that provides a stereoscopic image.
[0002] Display devices provide a wealth of visual and textual information through their screens. For example, the Smart AI Home Hub displays indoor temperature, outdoor weather, and the status of connected home appliances on its screen.
[0003] Existing display devices have insufficient stereoscopic representation of existing stereoscopic images, and when another image screen (e.g., a menu screen) is added to the existing stereoscopic images, the stereoscopic representation of the menu screen is insufficient or cannot be represented in stereoscopically.
[0004] Korean Registered Patent No. 10-2024314 provides a spatial touch recognition method capable of inputting coordinates by touching in space according to an image displayed on a display panel, and a spatial touch recognition device using the same.
[0005] The aforementioned Korean registered patent has a problem in that the three-dimensional representation of another video screen is insufficient when another video screen is added to an existing video.
[0006] The objective of the present invention is to provide a display device in which a three-dimensional representation is clearly expressed by three-dimensional images spaced apart from each other, and when another image screen (e.g., a menu screen) is added to an existing three-dimensional image, the three-dimensional representation of the menu screen is clearly expressed by changing the position where the menu screen appears.
[0007] The aforementioned objective of the present invention is achieved by the specific details described below.

[0147] The screen (211) of the upper display unit (21) and the screen (221) of the middle display unit (22) are positioned on the front of the upper display unit (21) and the middle display unit (22).
[0148] The screen (211) of the upper display unit (21) is positioned horizontally and faces downward (for example, toward the member (13)). The horizontal includes not only exactly horizontal but also obliquely slanted to approximate horizontal.
[0149] Image information, etc., appearing on the screen (211) of the upper display unit (21) faces downward (toward the lower member (13)). Then, the image information, etc., passes through the intermediate half-mirror unit (31) described later and appears vertically in the internal space (10s) (specifically, the internal space (10s2) on the side of the intermediate display unit (22)) (see FIG. 4). To elaborate, the horizontal image screen of the upper display unit (21) is displayed as a vertical image screen (211p) in the internal space (10s2) on the side of the intermediate display unit by the intermediate half-mirror unit (31) (see FIG. 4). The horizontal image screen indicates that the image screen is arranged horizontally, and the vertical image screen indicates that the image screen is arranged vertically.
[0150] Meanwhile, the screen (221) of the intermediate display unit (22) is positioned vertically and faces the front of the case (10). The vertical orientation includes not only exactly vertical orientation but also orientations that are slanted approximately vertically.
[0151] Image information, etc., displayed on the screen (221) of the intermediate display unit (22) faces the front of the case (10). Accordingly, the intermediate display unit (22) provides a vertical image screen (221p) (see FIG. 4).
[0152] The vertical video screen (211p) provided by the upper display unit (21) and the vertical video screen (221p) provided by the middle display unit (22) are separated by a preset distance. At this time, the vertical video screen (211p) provided by the upper display unit (21) is positioned in front of the vertical video screen (221p) provided by the middle display unit (22).
[0153] Since the vertical image screen (211p) of the upper display unit (21) and the vertical image screen (221p) of the middle display unit (22) are displayed spaced apart from each other, the user can view a three-dimensional image from the front of the case (10).
[0154] The lower display section (23) has a preset thickness. Also, the horizontal length of the lower display section (23) can be formed to be longer than the vertical length. The vertical length of the lower display section (23) can be shorter than the vertical length of the upper display section (21) or the middle display section (22).
[0155] The lower display unit (23) has a screen (231) of a preset size.
[0156] The lower display unit (23) has a plane formed in a horizontal direction and a vertical direction, and all or part of the plane may be composed of a screen (231).
[0157] Various image information and text information output by the lower display unit (23) are exposed to the outside through the screen (231).
[0158] The screen (231) of the lower display unit (23) is positioned on the front of the lower display unit (23).
[0159] When the lower display unit (23) is placed on the front support unit (141) of the lower structure (14), the screen (231) of the lower display unit (23) is positioned at a preset angle relative to the upper surface of the lower member (13).
[0160] The screen (231) of the lower display unit (23) is positioned obliquely, that is, the screen (231) is positioned diagonally and faces the ceiling member (12) toward the middle display unit (22) and / or the upper part of the middle display unit (22). To elaborate, the screen (231) of the lower display unit (23) is positioned obliquely so as to face the upper part of the rear interior space (10s2).
[0161] Image information, etc., appearing on the screen (231) of the lower display unit (23) is directed in a diagonal direction. Then, the image information, etc., passes through the lower half mirror unit (32) described later and appears on the intermediate half mirror unit (31) (see FIG. 5). To elaborate, the image screen (231p) output by the lower display unit (23) appears on one side of the intermediate half mirror unit (31) by the lower half mirror unit (32) (see FIG. 5).
[0162] The half mirror section (30) represents a mirror designed to reflect some of the light and transmit some of it. Since the half mirror section (30) represents a commonly used half mirror, a detailed description thereof is omitted.
[0163] The half mirror section (30) includes an intermediate half mirror section (31) and a lower half mirror section (32).
[0164] The middle half mirror section (31) has a preset size.
[0165] The horizontal length of the middle half mirror section (31) can be formed to be longer than the vertical length.
[0166] The middle half mirror section (31) has a preset thickness and is formed as a plane consisting of a horizontal direction and a vertical direction.
[0167] As described above, the middle half mirror section (31) transmits image information, etc., that appears on the screen of the upper display section (21), so that said image information, etc., appears in the internal space (10s) (specifically, the rear internal space (10s2) described later).
[0168] The middle half mirror section (31) is positioned obliquely in the internal space (10s). To elaborate, the middle half mirror section (31) is not horizontal or vertical but tilted to one side.
[0169] The middle half mirror section (31) is positioned at a preset angle relative to the ceiling member (12) or the lower member (13).
[0170] The middle half mirror section (31) includes one side (311) and the other side (312) in the vertical direction.
[0171] One side (311) of the middle half mirror section (31) is positioned to face the front of the case (10), and the other side (312) is positioned to face the back of the case (10).
[0172] Specifically, one side (311) of the intermediate half mirror section (31) is positioned toward the front edge of the lower surface member (13) and can be connected to a lower structure (14) located toward the front edge of the lower surface member (13) and / or in front. At this time, the lower display section (23) is positioned at the rear of the intermediate half mirror section (31).
[0173] A support surface (143) may be provided on the lower structure (14). The support surface (143) supports one side (311) of the intermediate half mirror part (31).
[0174] The support surface (143) can be positioned obliquely at the same angle as one side (311) of the intermediate half mirror part (31) to support one side (311) of the intermediate half mirror part (31).
[0175] And, the other side (312) of the middle half mirror section (31) is positioned adjacent to the upper edge of the middle display section (22) and can be connected to the ceiling member (12). The other side (312) of the middle half mirror section (31) is positioned in front of the middle display section (22).
[0176] A connecting portion (122) may be formed in the ceiling member (12). The other side (312) of the intermediate half-mirror portion (31) is connected to the connecting portion (122). The connecting portion (122) may be formed as a recess or a hole.
[0177] When the middle half mirror section (31) is positioned obliquely in the internal space (10s) of the case (10), the internal space (10s) of the case (10) can be divided into a front internal space (10s1) and a rear internal space (10s2) based on the middle half mirror section (31).
[0178] The front interior space (10s1) is an interior space (10s) located in front of the middle half mirror section (31), and the rear interior space (10s2) is an interior space (10s) located behind the middle half mirror section (31).
[0179] The upper display unit (21) is positioned above the front interior space (10s1) (above the front of the middle half mirror unit (31)). To elaborate, the upper display unit (21) is positioned on the front ceiling member (12) of the middle half mirror unit (31).
[0180] The middle display section (22) and the lower display section (23) are positioned in the rear internal space (10s2). Specifically, the middle display section (22) is positioned behind the middle half mirror section (31), and the lower display section (23) is positioned below the rear of the middle half mirror section (31). To elaborate, the middle display section (22) is positioned in the rear internal space (10s) (rear internal space (10s2)) of the middle half mirror section (31).
[0181] The image information (horizontal image screen) appearing on the screen (211) of the upper display unit (21) passes through the middle half mirror unit (31) and then appears as a vertical image screen (211p) in the rear internal space (10s2). At this time, the distance between the middle half mirror unit (31) and the vertical image screen (211p) is equal to the distance between the horizontal image screen and the middle half mirror unit (31). This is possible because the middle half mirror unit (31) is positioned obliquely in the internal space (10s).
[0182] Meanwhile, the planar shape of the intermediate half mirror part (31) can be formed in a rectangular shape or a trapezoidal shape.
[0183] For example, if speakers are placed at the left and right edges of the internal space (10s) of the case (10), a trapezoidal intermediate half mirror section (31) may be placed between the speakers.
[0184] The display device (1) of the present invention may include a film member (33).
[0185] The film member (33) is attached to the front of the middle half mirror part (31).
[0186] The film member (33) can be formed to be the same size as or smaller than the intermediate half mirror part (31).
[0187] The film member (33) is formed as a transparent thin film.
[0188] The film member (33) may be a commonly used ITO film (Indium Tin Oxide Film).
[0189] An ITO film refers to a film in which electrodes are formed by thinly depositing indium acid in a plasma state onto PET (polyethylene terephthalate), a plastic material. Because it is transparent despite the deposition of a metallic material, it is also called a transparent electrode.
[0190] ITO is used in various displays such as LCDs (Liquid Crystal Displays), PDPs (Plasma Display Panels), and Organic Light Emitting Diodes (OLEDs), and is also used for touch panels.
[0191] The user can touch the film member (33) to execute various applications embedded in the display device (1) of the present invention.
[0192] For example, a menu icon output by the lower display unit (23) can appear as a video screen (231p) on the middle half mirror unit (31), and the user can run an application by touching the video screen (231p).
[0193] The lower half mirror section (32) is positioned in the rear interior space (10s2) among the interior spaces (10s).
[0194] The lower half mirror section (32) is positioned on the lower structure (14) and is positioned above the lower display section (23). That is, the lower half mirror section (32) covers the lower display section (23) from above.
[0195] A seating portion (144) is formed in the lower structure (14). A lower half mirror portion (32) is seated in the seating portion (144).
[0196] The lower half mirror portion (32) has a preset size and can be formed larger than the size of the lower display portion (23).
[0197] The horizontal length of the lower half mirror part (32) can be formed to be longer than the vertical length.
[0198] The lower half mirror portion (32) has a preset thickness and is formed as a plane consisting of a horizontal direction and a vertical direction.
[0199] The lower half mirror section (32) transmits image information, etc., that appears on the screen (231) of the lower display section (23), so that said image information, etc., appears on the middle half mirror section (31). The reference numeral 231p in FIG. 5 indicates the image screen of the lower display section (23) that appears on the middle half mirror section (31).
[0200] When the lower half mirror part (32) is placed on the seating part (144) of the lower structure (14), the lower half mirror part (32) is placed horizontally. The horizontal includes not only exactly horizontal but also obliquely slanted to approximate horizontal.
[0201] Image information, etc., appearing on the screen (231) of the lower display unit (23) passes through the lower half mirror unit (32) and then appears on the middle half mirror unit (31). At this time, the distance between the image screen (231p) appearing on the middle half mirror unit (31) and the lower half mirror unit (32) is equal to the distance between the image information, etc., appearing on the screen (231) of the lower display unit (23) and the lower half mirror unit (32). This is possible because the middle half mirror unit (31) and the lower display unit (23) are positioned obliquely with respect to the lower half mirror unit (32) which is positioned horizontally.
[0202] The sensor unit (40) detects, for example, the user's hand movement (Gesture).
[0203] The sensor unit (40) may be a commonly used gesture sensor. For example, the sensor unit (40) may be an infrared (IR) gesture sensor.
[0204] Infrared rays emitted from the infrared emitting unit (IR LED) (41) reach the user's hand (H), are reflected, and reach the infrared receiver (42) (see (a) of FIG. 11).
[0205] The infrared receiver (42) may be, for example, a gesture chip. The infrared receiver (42) detects reflected infrared rays and identifies the gesture of the hand (H) from the infrared rays.
[0206] The configuration and operating principles of the gesture sensor are well known, so a detailed explanation thereof will be omitted.
[0207] The sensor unit (40) is positioned in front of the ceiling member (12) and faces the front interior space (10s1) (see FIGS. 9 and 10).
[0208] Referring to FIG. 11, the sensor unit (40) and the infrared receiver (42) are positioned below the hand (H). This is for ease of understanding. In the display device (1) of the present invention, the sensor unit (40) is positioned above the hand (H) (ceiling member (12)) (see FIG. 9 and FIG. 10).
[0209] The sensor unit (40) detects the movement (Gesture) of the user's hand (H) in the detection area of the sensor unit (40) (see FIGS. 9 to 11). The detection area of the sensor unit (40) represents the front internal space (10s1) located below the sensor unit (40) or an area near therefrom.
[0210] Specifically, as illustrated in FIG. 11, the sensor unit (40) detects that the user's hand (H) moves up and down (Fig. 11 (b)) and moves forward, backward, left, and right (Fig. 11 (c)).
[0211] By providing a sensor unit (40) in the display device (1) of the present invention, a menu scroll, etc. can be output from the display unit (20) by the user's movement (gesture), and the user can air touch the menu scroll, etc. Accordingly, applications embedded in the display device (1) of the present invention can be executed without touching a separate menu scroll, icon, etc.
[0212] The infrared receiver (42) is placed inside the receiver cover (43).
[0213] The receiver cover (43) may include a hole (431). Infrared rays reflected from the hand (H) can reach the infrared receiver (42) through the hole (431).
[0214] Additionally, the receiver cover (43) may include a transparent or opaque film (432) placed in the hole (431).
[0215] In FIG. 11 (a), reference numeral 44 represents a sensor unit cover (44) that protects the sensor unit (40), and reference numeral 45 represents a printed circuit board.
[0216] The sensor cover (44) can be formed in various shapes and has a hole that communicates with the hole (431) formed in the receiver cover (43).
[0217] The display device (1) of the present invention may include a leg portion (50).
[0218] Referring to FIGS. 1 to 3 and FIGS. 6 to 8, the leg portion (50) supports the case (10) of the present invention.
[0219] The leg portion (50) includes a first leg portion (51), a second leg portion (52), a third leg portion (53), and a fourth leg portion (54).
[0220] The first leg portion (51) and the second leg portion (52) are spaced apart at a predetermined distance on the left and right sides of the lower surface member (13) of the case (10).
[0221] The first leg portion (51) and the second leg portion (52) are formed in the shape of a hollow rod. The rod shape has a predetermined length in one direction.
[0222] One side of the first leg portion (51) and the second leg portion (52) is connected to the lower surface member (13) of the case (10), and the other side of the first leg portion (51) and the second leg portion (52) is in contact with the floor on which the display device (1) of the present invention stands.
[0223] The first leg portion (51) is supported by the third leg portion (53), and the second leg portion (52) is supported by the fourth leg portion (54).
[0224] The length of the first leg portion (51) and the length of the second leg portion (52) are the same and can vary.
[0225] Specifically, the length of the first leg portion (51) and the length of the second leg portion (52) can be increased from a preset length or restored to a preset length. At this time, the length of the first leg portion (51) and the length of the second leg portion (52) change to the same length simultaneously.
[0226] The configuration and length change method of the first leg part (51) is the same as the configuration and length change method of the second leg part (52). Accordingly, the configuration and length change method of the first leg part (51) will be explained below, and the configuration and length change method of the second leg part (52) will be omitted.
[0227] The first leg portion (51) includes an outer leg member (511) and an inner leg member (512).
[0228] The outer leg member (511) and the inner leg member (512) are formed in a hollow polyhedral tube or cylinder or a similar tube shape and have a preset length in one direction.
[0229] The outer leg member (511) and the inner leg member (512) include one side and the other side in the longitudinal direction.
[0230] One side of the outer leg member (511) and the inner leg member (512) faces the case (10), and the other side faces the floor on which the display device (1) of the present invention stands.
[0231] One end of the inner leg member (512) is positioned and fixed inside the case (10). Accordingly, when the inner leg member (512) moves up or down, the case (10) also moves up or down together with the inner leg member (512).
[0232] The outer leg member (511) accommodates the inner leg member (512). To elaborate, the inner leg member (512) is positioned inside the outer leg member (511) and can move along the longitudinal direction inside the outer leg member (511).
[0233] The inner leg member (512) can slide, for example, inside the outer leg member (511).
[0234] Specifically, the inner leg member (512) can move in one direction within the outer leg member (511) and can move in the opposite direction of said one direction.
[0235] When the inner leg member (512) moves in one direction, the length of the first leg portion (51) increases by the length the inner leg member (512) has moved. Then, when the inner leg member (512) moves in the opposite direction, the length of the first leg portion (51) is restored to its original length.
[0236] A screw member (513) and a nut member (514) are disposed inside the inner leg member (512).
[0237] The inner leg member (512) includes a through hole (512h).
[0238] The through hole (512h) is a hole that penetrates the interior of the inner leg member (512) in the longitudinal direction of the inner leg member (512).
[0239] A screw member (513) and a nut member (514) are placed in the through hole (512h).
[0240] The inner surface of the through hole (512h) and the outer surface of the nut member (514) are arranged to be able to move relative to each other.
[0241] The screw member (513) is formed in a rod shape with a preset length in one direction, and screw threads are formed on the outer surface.
[0242] The screw member (513) includes one side and the other side in the longitudinal direction.
[0243] One side of the screw member (513) is positioned inside the case (10), and the other side of the screw member (513) faces the floor on which the display device (1) of the present invention stands.
[0244] The screw member (513) is rotatably coupled to the inner leg member (512).
[0245] One side of the screw member (513) is rotatably coupled to one side of the inner leg member (512) and fixed to each other. To elaborate, when the screw member (513) rotates, the inner leg member (512) moves together with the screw member (513), and the inner leg member (512) does not move independently of the screw member (513).
[0246] When the screw member (513) rotates, the screw member (513) moves in a straight line together with the inner leg member (512).
[0247] When the screw member (513) rotates in one rotational direction (e.g., clockwise) or in the opposite direction of said rotational direction (e.g., counterclockwise), the screw member (513) moves together with the inner leg member (512) in one direction (e.g., upward) or in the opposite direction of said one direction (e.g., downward).
[0248] A gear (which may be named a ‘screw gear’) (5131) is disposed on one side of the screw member (513).
[0249] The screw gear (5131) is a conventional gear with teeth formed on the side.
[0250] The screw gear (5131) can be formed integrally with the screw member (513), or manufactured separately from the screw member (513) and coupled to one side of the screw member (513).
[0251] The screw gear (5131) is connected to a gear (which may be referred to as a ‘rotation shaft gear’) (551) connected to the rotation shaft of the drive motor (55) described later. Specifically, the teeth of the screw gear (5131) and the teeth of the rotation shaft gear (551) mesh together.
[0252] The rotational force of the drive motor (55) is transmitted to the rotation shaft gear (551) and the screw gear (5131), and as the screw gear (5131) rotates, the screw member (513) rotates.
[0253] The nut member (514) is formed in a rod shape with a predetermined length in one direction and includes a groove formed inside (which may be named a 'nut groove') (514h).
[0254] The nut groove (514h) is formed with a preset length in the longitudinal direction of the nut member (514). A screw groove is formed on the inner surface of the nut groove (514h).
[0255] The nut member (514) accommodates the screw member (513).
[0256] A screw member (513) is inserted into the nut groove (514h), and the threads of the screw member (513) can rotate along the screw groove formed in the nut groove (514h).
[0257] The nut member (514) does not rotate and is fixed inside the inner leg member (512) and the outer leg member (511).
[0258] Specifically, the nut member (514) includes one side and the other side in the longitudinal direction.
[0259] One side of the nut member (514) is positioned toward one side of the screw member (513) (or case (10)). The other side of the nut member (514) faces the floor on which the display device (1) of the present invention stands, and is secured by being coupled with a nut fixing part (5111) formed inside the outer leg member (511).
[0260] The nut fixing part (5111) is positioned and fixed inside the other side of the outer leg member (511).
[0261] The nut fixing part (5111) includes a groove or a hole, and the other end of the nut member (514) is inserted into the groove or hole and fixed.
[0262] The principle of how the length of the first leg (51) increases is as follows.
[0263] When the screw member (513) rotates in one rotational direction (e.g., clockwise), the nut member (514) is fixed, so the threads of the screw member (513) rotate along the screw groove of the nut member (514), and the screw member (513) moves in one direction (e.g., upward). At this time, the inner leg member (512) is coupled with the screw member (513) and moves in one direction together with the screw member (513). The inner surface of the through hole (512h) of the inner leg member (512) slides in one direction along the outer surface of the nut member (514).
[0264] And, the principle by which the length of the first leg (51) is restored to its original length is as follows.
[0265] When the screw member (513) rotates in the opposite direction of one rotation direction (e.g., counterclockwise), since the nut member (514) is fixed, the threads of the screw member (513) rotate along the screw groove of the nut member (514), and the screw member (513) moves in the opposite direction of one direction (e.g., downward). At this time, the inner leg member (512) is coupled with the screw member (513) and moves together with the screw member (513) in the opposite direction of one direction.
[0266] The third leg portion (53) supports the first leg portion (51), and the fourth leg portion (54) supports the second leg portion (52).
[0267] The third leg portion (53) and the fourth leg portion (54) are formed in a rod shape. The rod shape has a predetermined length in one direction.
[0268] The third leg portion (53) and the fourth leg portion (54) have one side and the other side in the longitudinal direction.
[0269] One side of the third leg portion (53) is connected to a point between one side and the other side of the first leg portion (51) (specifically, the outer leg member (511)), and the other side of the third leg portion (53) is in contact with the floor on which the display device (1) of the present invention stands.
[0270] And, one side of the fourth leg portion (54) is connected to a point between one side and the other side of the second leg portion (52) (specifically, the outer leg member (511)), and the other side of the fourth leg portion (54) is in contact with the floor on which the display device (1) of the present invention stands.
[0271] The third leg portion (53) can be formed in various shapes and lengths to support the case (10) and the first leg portion (51), and the fourth leg portion (54) can be formed in various shapes and lengths to support the case (10) and the second leg portion (52).
[0272] The display device (1) of the present invention includes a driving motor (55).
[0273] The drive motor (55) represents a conventional motor in which the rotating shaft rotates by the supply of electricity. Since the configuration and operating principle of the motor are well known, a detailed explanation thereof is omitted.
[0274] Electricity supplied to the drive motor (55) can be supplied from the outside by a wire, or by a battery built into the display device (1) of the present invention.
[0275] The drive motor (55) is placed and fixed inside the case (10).
[0276] Additionally, the drive motor (55) is positioned on one side of the inner leg member (512) of the first leg portion (51). One side of the inner leg member (512) includes a motor receiving portion (512a) that accommodates the drive motor (55). That is, a motor receiving portion (512a) is formed on one side of the inner leg member (512). The motor receiving portion (512a) is positioned and fixed inside the case (10).
[0277] A rotational shaft gear (551) is positioned on the rotational shaft of the drive motor (55). The rotational shaft gear (551) meshes with a screw gear (5131) positioned on one side of the screw member (513). At this time, the central axis line passing through the center of the rotational shaft gear (551) and the central axis line passing through the center of the screw gear (5131) are orthogonal to each other.
[0278] When the drive motor (55) operates, the rotational force of the rotation shaft is transmitted to the rotation shaft gear (551) and the screw gear (5131). Accordingly, the screw member (513) rotates. As the screw member (513) rotates, the lengths of the first leg portion (51) and the second leg portion (52) can be extended or restored to their original lengths.
[0279] When the lengths of the first leg portion (51) and the second leg portion (52) increase, the position of the case (10) rises. Then, when the lengths of the first leg portion (51) and the second leg portion (52) are restored to their original lengths, the position of the case (10) falls.
[0280] The user can raise or lower the position of the case (10) to more easily recognize the image information displayed by the display device (1) of the present invention.
[0281] The user may operate, for example, a button provided on the case (10) or an icon displayed by the display unit (20) to raise or lower the position of the case (10). Accordingly, the driving motor (55) provided on the first leg unit (51) and the second leg unit (52) can be driven.
[0282] As described above, the display device (1) of the present invention includes an upper display unit (21), an intermediate display unit (22), and a lower display unit (23), and additionally includes an intermediate half mirror unit (31) and a lower half mirror unit (32).
[0283] For example, the middle display section (22) corresponds to the main display, the upper display section (21) corresponds to the sub display, and the lower display section (23) corresponds to the menu display. Also, the middle half mirror section (31) corresponds to the main half mirror, and the lower half mirror section (32) corresponds to the sub half mirror.
[0284] The screen (221) of the middle display unit (22) (Main display) is positioned to face the front of the case (10), and the screen (211) of the upper display unit (21) (Sub display) is positioned to face from the top to the bottom of the internal space (10s) of the case (10).
[0285] The video screen (221p) output by the intermediate display unit (22) (Main display) and the video screen (211p) output by the upper display unit (21) (Sub display) are implemented as a two-layered display screen by means of the intermediate half mirror unit (31) (Main half mirror) arranged in a diagonal direction.
[0286] And, a lower display unit (23) (Menu display) is positioned below the middle half mirror unit (31) so as to be orthogonal to the middle half mirror unit (31), and a lower half mirror unit (32) (Sub half mirror) is positioned diagonally to the front of the lower display unit (23).
[0287] The image screen (231p) (e.g., a menu icon) output by the lower display unit (23) is displayed on the middle half mirror unit (31). That is, as the lower display unit (23) is activated (On, Off / Function Mapping), a virtual menu icon appears on the middle half mirror unit (31). For example, when the sensor unit (40) detects the user's hand (H) or when the hand (H) touches the film member (33), the lower display unit (23) can activate the image screen (231p).
[0288] FIG. 12 shows a vertical video screen (211p) output by an upper display unit (21), a vertical video screen (221p) output by a middle display unit (22), and a video screen (menu icon) (231p) output by a lower display unit (23). The video screens (211p, 221p, 231p) implement a layered display composed of three layers.
[0289] A film member (33) (e.g., ITO Film) is attached to the intermediate half mirror section (31). The user can view a menu icon displayed on the intermediate half mirror section (31) and touch the film member (33) above the menu icon to execute an application built into the display device (1) of the present invention. FIG. 13 shows the user touching the image screen (231p) (menu icon) displayed on the intermediate half mirror section (31).
[0290] In addition, a sensor part (40) (e.g., an IR Gesture sensor) is placed in front of the ceiling member (12).
[0291] The user can execute an application embedded in the display device (1) by moving the hand (H) in a preset pattern within the detection area of the sensor unit (40), or by moving the hand (H) to move or select an icon or scroll to execute an application embedded in the display device (1) (see FIGS. 9 to 11 and FIG. 14). FIG. 14 (a) shows the user selecting content by moving the hand (H) in a preset pattern. FIG. 14 (b) shows a video screen (231p) corresponding to a menu icon appearing on the existing screen. Since the menu icon is floating on the existing screen, the user can intuitively select or operate the menu icon.
[0292] FIG. 15 illustrates an example of a video screen output from a display unit (20). FIG. 15 (a) is a video screen showing a Smart AI Home Hub, (b) is a video screen showing meditation, (c) is a video screen showing an Audio Book, (d) is a video screen showing a Music Player, and (e) is a video screen showing Karaoke.
