FIGS. 1A and 1B are schematic diagrams illustrating an overall system for displaying a screen of an electronic apparatus in accordance with an embodiment of the present invention.
Referring to FIG. 1A, components for displaying a screen of an electronic apparatus 100 may include a screen 10, the electronic apparatus 100, a portable apparatus 200, a proximity sensor 220, a touch panel 240, a support frame 245, a large format display (LFD) apparatus 260, a fixed stand 265, and a projection-type display apparatus (for example, a projector 280).
A wall 10a may include the screen 10. The screen 10 may be positioned on the surface of the wall 10a facing the projector 280. Alternatively, the screen 10 may be positioned independently of the wall 10a. The screen 10 may include a screen using a white wall surface or a white film or fiber with uniform reflection and less glare. The screen 10 displays content (for example, a content having a resolution of full high definition (FHD, 1920×1080 pixels) or more) projected from the projector 280. In the embodiment of the present invention, a 2K-resolution content may be used as the term referring to a content having a resolution of FHD or more. In the embodiment of the present invention, the “content” may be used as the term including an idle video, a hooking video, a product video, a hooking UI, a product UI, or the like which is output from a display apparatus and/or a projection-type display apparatus by control of the electronic apparatus. The resolution of the content may include an UHD or a FHD. In addition, the “content” may include videos, images, texts, web documents, for example.
The screen 10 may include a material in which a gain indicating a reflection coefficient of light projected on the screen is large and an angle indicating left/right viewing angles at which the reflection coefficient is constantly maintained is in a range of approximately 20° to 60°.
In the wall 10a, an opening 10b through which the LFD apparatus 260 is inserted may be formed. An area of the opening 10b is smaller than an area of the screen 10. The opening 10b may be positioned closer to either the left side or the right side of the screen 10. In addition, the opening 10b may be positioned at the central area of the screen 10.
The electronic apparatus 100 may be wirelessly connected, or connected through a wired connection, to some or all of the components of the system. The electronic apparatus 100 may be electrically connected and/or in communication with some or all of the components of the system. The electronic apparatus 100 may control the connected components (for example, the LFD apparatus, the projector, etc.). The electronic apparatus 100 will be described below in detail with reference to FIGS. 2A and 2B.
The portable apparatus 200 may be remotely connected to or may be in communication with the electronic apparatus 100 to manage and control the system. The portable apparatus 200 and the electronic apparatus 100 may be connected with each other in a wired or wireless manner using a network connection apparatus (for example, a router or a sharer). The portable apparatus 200 may manage the electronic apparatus 100 and the components which are connected with the electronic apparatus 100 using a centerstage management system (CMS) application installed in the portable apparatus 200 or the electronic apparatus 100. The portable apparatus 200 may transmit control signals to the connected electronic apparatus 100. The control signals may include control signals capable of outputting contents to the LFD apparatus 260 and the projector 280 and control signals capable of downloading contents from the outside to the electronic apparatus 100.
The proximity sensor 220 detects a user approaching a set area (for example, within approximately 1 m from the screen 10) of the screen 10 or the LFD apparatus 260 as non-contact or contact. The proximity sensor 220 which detects the user's approach may transmit analog or digital signals corresponding to the detected user's approach to the electronic apparatus 100.
Various types of the proximity sensors 220 may be provided. The proximity sensor 220 may include a magnetic type proximity sensor, an inductance type proximity sensor, a high-frequency oscillation type proximity sensor, a capacitive type proximity sensor, an infrared type proximity sensor, a camera for closed circuit TV (CCTV), and the like.
The proximity sensor 220 may be provided at a position (for example, a position where the shadow of the proximity sensor 220 is not displayed on the screen 10) where the proximity sensor 220 is not interfering with the content projected from the projector 280. In addition, the proximity sensor 220 may be positioned in an area between the screen 10 and a user.
The touch panel 240 receives a touch of the user. The touch panel 240 may receive a single-touch or multi-touch by a user's body (for example, fingers including the thumb) or an input unit (for example, a stylus which is not shown). The input unit is not limited as long as it can detect a touch input on the touch panel 240 corresponding to various touch detection methods.
The touch panel 240 may transmit analog signals corresponding to the input user's touch to a touch panel controller (not shown). The touch panel controller may convert the received analog signals to transmit the converted signals to the electronic apparatus 100. The electronic apparatus 100 may calculate a position (for example, X and Y coordinates) corresponding to the user's touch using the received signals.
The touch panel 240 may be implemented as a capacitive type touch panel, a resistive type touch panel, an infrared type touch panel, or an acoustic type touch panel, but the touch panel 240 is not limited thereto.
The touch panel 240 is positioned between the support frame 245 and the LFD apparatus 260. The touch panel 240 may be coupled to a bezel or back cover (not shown) of the LFD apparatus 260 (for example, using adhesive, adhesive tape, or a joint member such as a screw, and the like).
The touch panel 240 may be integrally formed with the LFD apparatus 260. The touch panel 240 may be implemented in a top area (for example, on-cell scheme) of a display unit (not shown) of the LFD apparatus 260 or an inner area (for example, in-cell scheme) of the display unit (not shown) of the LFD apparatus 260. The thickness when the touch panel 240 and the LFD apparatus 260 are integrated with each other may be reduced compared to the thickness when the touch panel 240 and the LFD apparatus 260 are separately formed. A weight supported by the support frame 245 when the touch panel 240 and the LFD apparatus 260 are integrated with each other may be also reduced compared to a weight supported by the support frame 245 when the touch panel 240 and the LFD apparatus 260 are separately formed. In addition, a size (for example, a depth of the support frame 245 is reduced) of the support frame 245 may be also minimized when the touch panel 240 and the LFD apparatus 260 are integrated with each.
The support frame 245 may accommodate the coupled touch panel 240 and LFD apparatus 260. The support frame 245 may support the coupled touch panel 240 and LFD apparatus 260. In addition, the support frame 245 may be fitted into the opening 10b of the wall 10a. The vertical and horizontal widths of the support frame 245 are small so as to minimize (for example, to reduce) the interference with the content projected from the projector 280.
The LFD apparatus 260 displays a synchronized content received from the electronic apparatus 100. The content received from the electronic apparatus 100 is synchronized with the content output from the projector 280. The content displayed in the LFD apparatus 260 may be a content having an UHD resolution (for example, approximately 4,000×2,000 pixels) that is approximately four times an FHD resolution. The UHD resolution may include 4,096×2,160 pixels or 3,840×2,160 pixels, for example.
In the embodiment of the present invention, a 4K-resolution content may be used as the term referring to a content having a resolution of UHD or more. The LFD apparatus 260 may be a display apparatus capable of outputting a content having the UHD resolution. In addition, the LFD apparatus 260 may be a display apparatus capable of outputting a content having the FHD resolution.
In the embodiment of the present invention, a diagonal length of a display screen of the LFD apparatus 260 may be approximately 1,520 mm (60 inches) or more. In the embodiment of the present invention, a diagonal length of a display screen of a Small Format Display (SFD) apparatus may be smaller than the diagonal length of the display screen of the LFD apparatus 260. In addition, the SFD apparatus refers to a display apparatus capable of outputting a content resolution equal to or lower than the resolution of the content displayed in the LFD apparatus 260. For example, when the diagonal length of the display screen of the LFD apparatus 260 is approximately 2,150 mm (85 inches), a diagonal length of a display screen of an SFD apparatus 290 may be approximately 1,160 mm (46 inches).
In the embodiment of the present invention, the display apparatus having a same diagonal length of the display screen may have a diagonal length of a display screen having a margin of approximately ±50 mm. For example, when the diagonal length of the display screen is approximately 2,150 mm, the display apparatus having the same diagonal length of the display screen may have a diagonal length of a display screen of approximately 2,100 mm to 2,200 mm.
While the LFD apparatus 260 outputs the 4K-content resolution, the SFD apparatus 290 may output a 2K-content resolution. The SFD apparatus 290 may be a display apparatus capable of outputting a content having an FHD resolution. In addition, the SFD apparatus 290 may display the same 4K-content resolution as that of the LFD apparatus 260, and its diagonal length may be shorter than the diagonal length of the LFD apparatus 260. In the embodiment of the present invention, the diagonal length of the display screen of the SFD apparatus 290 may be approximately 1,160 mm (46 inches).
The screen of the content output from the LFD apparatus 260 may be the same as the screen of the content projected from the projector 280 to the screen 10. The content output from the LFD apparatus 260 may have the same screen as that of the content projected from the projector 280 to the screen 10, and have a different resolution from that of the content projected from the projector 280 to the screen 10. The content displayed in the LFD apparatus 260 may be displayed with a brightness (for example, brighter) different than the brightness of the same content projected from the projector 280 to the screen 10. The screen of the content displayed in the LFD apparatus 260 may be a part of the screen of the synchronized content projected from the projector 280 to the screen 10.
The content which is received from the electronic apparatus 100 and is output to the LFD apparatus 260 is synchronized with the content projected from the projector 280 to the screen 10.
A variety of types and sizes of products (for example, a refrigerator, a washing machine, an electric range, etc.) which can be displayed in the LFD apparatus 260 may be provided. The size (horizontal length (width)×vertical length (height): approximately 2,004×1,085 mm) of the LFD apparatus 260 may be larger than an actual size (approximately 908×1850 mm) of the displayed product (for example, a refrigerator). For example, the size (for example, an area of the screen) of the LFD apparatus 260 is larger than the actual size (for example, an area of the entire surface of the product) of the displayed product by approximately 1.05 times or more. The size of the LFD apparatus 260 may be larger than the actual size (approximately 686×990 mm) of the displayed product (for example, an area of an entire surface of a washing machine) by approximately 2.5 times or more. In addition, the size of the LFD apparatus 260 may be larger than the actual size (approximately 740×920 mm) of the displayed product (for example, an area of an entire surface of an electric range) by approximately 2.5 times or more. In addition, in the case of a small-sized product such as a mobile phone, a note PC, or a tablet PC, the SFD apparatus 290 as well as the LFD apparatus 260 having a screen size larger than the small-sized product may be applied. The term “large-size” has a relative meaning, and may be used as the term referring to a display apparatus having a screen having a size larger than the size of the product displayed on the screen.
The LFD apparatus 260 having the size (horizontal length×vertical length) larger than the size of the displayable product may be selected to be positioned at the opening 10b of the wall 10a. 
Through the system including the LFD apparatus 260 and the projection-type display apparatus 280, products having various kinds and sizes may be introduced, and therefore the number of products, the size of the space, and costs may be reduced when compared to an actual showroom. In addition, through the system including the LFD display apparatus 260 and the projection-type display apparatus 280, products having various kinds and sizes may be introduced to users in a single place without burdening the users with the need to move around the inside of the showroom, thereby providing a new shopping experience.
The LFD apparatus 260 may be supported by the fixed stand 265. The LFD apparatus 260 coupled to the touch panel 240 may be supported by the fixed stand 265. The LFD apparatus 260 integrally formed with the touch panel 240 may be supported by the fixed stand 265. In addition, the support frame 245, the touch panel 240, and the LFD apparatus 260 may be supported by the fixed stand 265.
The projector 280 enlarges a synchronized 2K-resolution content received from the electronic apparatus 100 and projects the enlarged content to the screen 10. The content received from the electronic apparatus 100 is synchronized with the content output to the LFD apparatus 260. In addition, the projector 280 may enlarge a 4K-resolution content received from the electronic apparatus 100 and projects the enlarged content to the screen 10. The projector 280 may have a brightness of approximately 3000 ANSI lumens or more to correspond to the resolution of the projected content. When the resolution of the content is increased, the brightness (for example, ANSI lumens) of the projector 280 may be increased. The projection-type display apparatus may include the projector 280.
The synchronized content may denote two contents. For example, a content screen output from the LFD apparatus 260 may be a part of a content screen output from the projector 280. This may be easily determined when comparing a size (for example, horizontal length×vertical length) of the screen 10 and a screen size (for example, horizontal length×vertical length) of the LFD apparatus 260.
The synchronized content output from the LFD apparatus 260 may be a content of the 4K-resolution, and the synchronized content output from the projector 280 is a low-resolution content compared to the content output from the LFD apparatus 260. The synchronized low-resolution content output from the projector 280 and the synchronized high-resolution content output from the LFD apparatus 260 may be overlapped and displayed on the screen 10. In addition, the low-resolution content in which a screen area corresponding to the screen of the LFD apparatus 260 is masked may be output from the projector 280. The high-resolution content may be output to the screen of the LFD apparatus 260, separately from the low-resolution content including the masked screen area output from the projector 280.
Referring to FIG. 1B, most of components 200 to 280 are the same as those in FIG. 1A. The electronic apparatus 100 of FIG. 1A may be reconfigured as the electronic apparatus 100 connected with the touch panel 240 and the LFD apparatus 260, a first electronic apparatus 101 connected with the projector 280, and a second electronic apparatus 102 connected with the proximity sensor 220. The electronic apparatus 100, the first electronic apparatus 101, and the second electronic apparatus 102 may be connected with each other in a wired or wireless manner. When signals corresponding to a user's approach are received from the second electronic apparatus 102, the electronic apparatus 100 may control the second electronic apparatus 102 to output a synchronized content corresponding to the user's approach from the LFD apparatus 260 and the projector 280.
It will be readily understood by those persons skilled in the art that a component of the system connected with the first electronic apparatus 101 and the second electronic apparatus 102 may be changed. In addition, the first electronic apparatus 101 and the second electronic apparatus 102 may be implemented as a single third electronic apparatus (not shown, 103). The third electronic apparatus may be connected with the proximity sensor 220 and the projector 280. The third electronic apparatus may be connected with the electronic apparatus 100 in a wired or wireless manner. The electronic apparatus 100 may control the third electronic apparatus.

The hooking video 301 may include a hooking video 320 output from the LFD apparatus 260 and hooking videos 360 and 361 output from the projector 280. The screen size of the hooking video 320 displayed on the LFD apparatus 260 may be smaller than the screen size of each of the hooking videos 360 and 351 output from the projector 280.
The hooking video 301 may be output from the LFD apparatus 260 and the projector 280 in such a manner that various food material, vegetables, fruits, and the like are sucked into a storage space of the product (for example, the refrigerator with all its doors opened) displayed on the LFD apparatus 260 while looking as if they are sucked into a vortex. The doors of the refrigerator into which the various food materials, vegetables, or fruits are all sucked are all closed and then at least one of the doors may be slightly opened. The slight opening of the upper right door of the refrigerator means that the output of the hooking video 301 is completed. In addition, when the slight opening of the upper right door of the refrigerator is output and “center stage” is output from the projector 280, it means that the output of the hooking video 301 is completed. In addition, when the doors of the refrigerator are all closed as shown in FIG. 4J, the output of the hooking video 301 may be completed.
It will be readily understood by those persons skilled in the art that various hooking videos (for example, sudden disappearing and the like) as well as the hooking video 301 which is sucked into the vortex may be displayed. The user who approaches the screen 10 may have interest in and fun with the product by the displayed hooking video 301.
The hooking video 301 may be distinct from the idle video 300 shown in FIGS. 4A to 4j. The idle video is a video output in a standby state which is an idle stage, and the hooking video 301 is a video output in an intermediate stage from the idle stage to a product stage.
The content output from the electronic apparatus 100 may be classified into 3 stages. The 3 stages may include an idle stage (not shown), a hooking stage (not shown), and a product stage (not shown).
In addition, one stage may include 3 layers. The 3 layers may be an interaction layer (not shown) corresponding to the user's touch, a player layer (not shown) corresponding to content output, and a sensor and UI layer (not shown) corresponding to the user's approach. One or two layers may be activated in the single stage. In addition, the 3 layers may be all activated in the single stage.
In the idle stage which is the first stage, only the player layer that is the top layer in the idle stage is activated. The player layer may output the idle video 300 to the LFD apparatus 260 and the projector 280 in accordance with the control by the control unit.
When the user's approach is detected by the proximity sensor 220, the idle stage is changed to the hooking stage which is the second stage. In the hooking stage, the player layer which outputs the hooking video and the sensor and UI layer which receives a user's input are respectively activated. In the hooking stage, the sensor and UI layer is changed to the top layer overlapping the player layer to be displayed in accordance with the control by the control unit. The sensor and UI layer may include a hooking UI for user's input (for example, touch or hovering). The hooking UI may include icons, buttons, images, or text. The size (horizontal length×vertical length) of the hooking UI of the sensor and UI layer may be the same as the size (horizontal length×vertical length) of the hooking video output from the player layer. In addition, the coordinate origin (0, 0) the hooking UI of the sensor and UI layer may be the same as the coordinate origin (0, 0) of the hooking video output from the player layer. A margin except an icon area, a button area, an image area, or a text area included in the hooking UI may be transparently displayed.
When a user's input is detected by the hooking UI, the hooking stage is changed to the product stage which is the third stage in accordance with the control by the control unit. In the product stage, the interaction layer which displays the product UI and the player layer which displays the product video are activated. In the product stage, the interaction layer is changed to the top layer overlapping the player layer in accordance with the control by the control unit. The interaction layer may include a product UI for the user's input (for example, touch or hovering). The product UI may include icons, buttons, images, or text. The size (horizontal length×vertical length) of the product UI from the product layer may be the same as the size (horizontal length×vertical length) of the product video output from the player layer. In addition, the coordinate origin (0, 0) of the product UI layer may be the same as the coordinate origin (0, 0) of the product video output from the player layer. Even in the product UI after operation S304 of FIG. 3A, the coordinate origin (0, 0) of the product UI layer and the coordinate origin (0, 0) of the product video output from the player layer may be implemented as the same. A margin except an icon area, a button area, an image area, or a text area included in the product UI may be transparently displayed.
When a user's input is detected by the icon of the product UI, the control unit may output a product video, corresponding to the icon where the user's input is detected, to the player layer. When the product video is output in the player layer, the player layer is the top layer. When the output of the product video is completed, the interaction layer is changed again to be the top layer in place of the player layer.
When the user's input is not detected within a set time (for example, one minute which is changeable) in the product UI, the control unit may change the product stage to the idle stage. The control unit outputs the idle video in the idle stage.
In operation S305 of FIG. 3A, a hooking UI is output to the LFD apparatus.
Referring to FIG. 5D, the control unit outputs a hooking UI 321 to the LFD apparatus 260 in response to the detected user's approach.
The hooking UI 321 which is the top layer in the hooking stage may include icons, buttons, images, or text which can receive the user's input. The hooking UI 321 may overlap on the hooking video 301 output in the player layer to be displayed. The hooking UI 321 may include an icon 325 corresponding to “Touch to Start”. In the hooking UI 321, a margin except the icon 325 may be transparently displayed. When the interaction layer is displayed, the player layer may be positioned as the lower layer than the interaction layer.
The control unit may output the hooking UI 321 to the LFD apparatus 260 and the projector 280 in response to the detected user's approach.
In operation S306 of FIG. 3A, a first touch is detected in the hooking UI by the touch panel.
Referring to FIG. 5D, a user performs the first touch on the icon 325 displayed on the hooking UI 321. The control unit may detect the first touch 326 using the touch panel 240 and a touch panel controller (not shown).
