## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority benefit of Chinese Patent Application Number CN 201310545557.9, entitled “A TRANSPARENT SHOW CASE,” filed on Nov. 6, 2013, by Ka-Leung Sin and Jason Felix Chiu Tsz Kiu and, which is incorporated herein by reference.
FIELD
The present specification relates to a display system.
BACKGROUND
The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also be inventions.
In the evolution of display panels, one direction is related to transparent display panels. Current display panel technologies include transparent liquid-crystal display (TLCD), organic light-emitting diode (OLED), plasma display panel, as well as transparent holographic rear projection film. Samsung announced that sample products of 22′′ TLCD were produced from March 2011. Samsung also produced TLCD of larger sizes (e.g., 46′′ in size).
One of the applications of transparent display panels is to build transparent showcases. Current showcases may use one transparent display panel on a side of the showcase to display merchandise inside the showcase to the public that face the transparent display panel. The transparent display panels can play commercial and/or promotional videos or other multimedia content while at the same time allow people to see through the transparent display panels and observe the merchandise inside showcases. A turntable may be installed inside the showcase and rotates to show different sides of merchandise in accordance with the video played on the transparent display panel.
In current showcases, the movements of display items are very limited (e.g., currently only rotational movement on a turntable), which limit the display of items and the multimedia played on the display panels. For example, if the display item is placed on the left side of the showcase and needs to be seen through the left part of display panel, the video played on the left side of display panel, if any, would have to be in light color to make the left part of the display panel transparent or semi-transparent. Thus, the part of display panel that shows the video in full color thus would be limited to the right part of display panel that is opaque. Even if a turntable is used to rotate the display item, movement of item is limited to rotation on the turntable. Furthermore, current showcases may not recognize the use of light effects to enhance the presentation of the display items. The use of current showcases is limited to display merchandise or products, without showing combinations of movements of items and display of performances (e.g., processes such as tours or shows on stage). This specification recognizes the needs to improve the showcases or display systems with the use of display panels to create a more attractive presentation of exhibitions or performances.
Some showcases have been disclosed in China Patent Application number CN 201210315770.6 and China Patent Application number CN201220495946.6, which are hereby incorporated by reference.

FIG. 8B shows lighting system 800b may include axle 802, gear 804, motor gear 806, motor shaft 808, motor 819, color filter 874, variable resistor 875, and light 876. In other embodiments, the assembly of lighting system 800b may not have all of the elements or features listed and/or may have other elements or features instead of, or in addition to, those listed.
Axle 802, gear 804, motor gear 806, motor shaft 808, and motor 819 may be similar to the axle 702, gear 704, motor gear 706, motor shaft 708, and motor 719, respectively, which were discussed above in conjunction with FIG. 7E. However, in FIG. 8B axle 802 supports color filter 874 rather than the turntable 701 of FIG. 7E. In FIG. 8B, the motor 819 may be an embodiment of either of the fourth motor 853 and the fifth motor 855 of FIG. 8A. Color filter assembly 874 may be associated with a gear (e.g., gear 804). For example, the color filter assembly 874 may have teeth along the perimeter of the gear that may be attached to the bottom of color filter assembly 874. Color filter assembly 874 may be a disk with a plurality of windows in which each of the windows has a different color filter. Variable resistor 875 may control the current and/or voltage and therefore the power supplied to the light. Varying the power supplied to the light causes the intensity of the light to vary. A controller may be communicatively attached to, and automatically control, variable resistor 875, so that the controller may adjust the intensity of a particular color of light, and thereby vary the brightness and/or color of light. Light 876 produces multiple frequencies of light simultaneously. For example, the combination of the different frequencies of light emitted by light 876 may appear as white light (in which case light 876 would be a white light). Light 876 shines through a color filter of color filter assembly 874 to produce light of a particular color. Motor 819 rotates motor shaft 808, which rotates motor gear 806. Motor gear 806 may include holes in the gear for light to shine through. Motor gear 806 engages the gear associated with/attached to color filter assembly 874, so that as motor gear 806 turns, color filter assembly 874 turns. Motor 819 is actuated by the controller, which determines how long to run motor 819 in order to place the desired color filter of color filter assembly 874 under light 876 to produce a desired color of light. In another embodiment, the color filter assembly 874 is held stationary, while the light 876 is placed on a turntable. In which case, the light 876 is moved, via the turntable to align light 876 with a desired color filter. Alternatively three different colored light bulbs may be used for adjusting the color of the light. Light 876 of FIG. 8B may be an example of lighting device 851a or 851b. Turntable 701 of FIG. 8B may be an embodiment of second turntable 852 or third turntable 854 (or other turn tables), for example. Gear 804 of FIG. 8B may be an embodiment of gear wheel 856 or 857, for example. Motor 819 of FIG. 8B may be an example of motor 853 or 855. In at least one embodiment, the assembly of FIG. 8B may be substituted for some or all of the devices and/or structures of lighting module 850 of FIG. 8A. For example, in at least one embodiment, the assembly of FIG. 8B is connected to control module 830 and replaces the fifth motor 855, third gear wheel 857, second lighting device 851b, and third turntable 854. Alternatively or additionally, the assembly of FIG. 8B is connected to control module 830 and replaces the fourth motor 853, first lighting device 851a, second turntable 852, and second gear wheel 856.
FIG. 8C shows an embodiment of color filter assembly 874 with axle 802 of FIG. 8B. Color filter assembly 874 may include windows 874a-d. In other embodiments, the assembly of color filter assembly 874 may not have all of the elements or features listed and/or may have other elements or features instead of, or in addition to, those listed.
One of windows 874a-d may include clear transparent piece of material (glass or plastic) and/or may be empty. The other three of windows 874a-d may have different color filters, each filter may be a different primary color, such that combinations of the light form the different filters may be used to form other colors of light within a continuum of colors within a color space formed by the three filters. For example, window 874a may be clear, and windows 874b-d may be red, green and yellow, respectively; red, blue, and yellow, respectively; red, blue and green, respectively; or magenta, cyan, and yellow, respectively. By including three color filter assemblies, such as color filter assembly 874, different colors from different filters may be mixed to form new colors that are different than the colors of the filters.
FIG. 8D shows another embodiment of lighting system 800b, which may include turntable 701, axle 802, gear 804, motor gear 806, motor shaft 808, motor 819, color filter 874, variable resistor 875, and light 876. In other embodiments, the assembly of lighting system 800b may not have all of the elements or features listed and/or may have other elements or features instead of, or in addition to, those listed.
Turntable 801, axle 802, gear 804, motor gear 806, motor shaft 808, motor 819, color filter 874, variable resistor 875, and light 876 were discussed in conjunction with FIG. 8B. Further details of an embodiment of color filter 874 are discussed in conjunction with FIG. 8C. The embodiment of FIG. 8D differs from the embodiment of FIG. 8C in that in FIG. 8D light 876 is mounted on the turntable 701 and filter 874 is held stationary (instead of holding light 876 in a stationary position and placing color filter 874 on the turntable, as shown in FIG. 8B). In the embodiment of FIG. 8D, electrical connections are established with light 876 via wires and electrical connections in turntable 701 (rather than directly with light 876 as in FIG. 8B). Variable resistor 875 establishes an electrical connection with light 876, via axle 802 and turntable 701. In the embodiment of FIG. 8D, there is no need for gear 804 to have holes. Instead, gear 804 may be a solid disk with teeth jutting out at the perimeter, because in the embodiment of FIG. 8B, light does not need to pass through gear 804. The lighting systems of FIGS. 8B and 8D may be used together in the same embodiment. For example, there may be beams of colored light shined onto the display item 111. One or more the light beams may be produced by the lighting system of FIG. 8B, and one or more of the light beams may be produced by the lighting system of FIG. 8D. Light 876 of FIG. 8D may be an example of lighting device 851a or 851b (FIG. 8A). Turntable 701 of FIG. 8D may be an embodiment of turntable 852 or 854 (FIG. 8A) (or other turn tables), for example. Gear 804 of FIG. 8D may be an embodiment of gear wheel 856 or 857 (FIG. 8A), for example. Motor 819 of FIG. 8D may be an example of motor 853 or 855 (FIG. 8A). In at least one embodiment, the assembly of FIG. 8D may be substituted for some or all of the devices and/or structures of lighting module 850 of FIG. 8A. For example, in at least one embodiment, the assembly of FIG. 8D is connected to control module 830 and replaces the fifth motor 855, third gear wheel 857, second lighting device 851b, and third turntable 854. Alternatively or additionally, the assembly of FIG. 8D is connected to control module 830 and replaces the fourth motor 853, first lighting device 851a, second turntable 852, and second gear wheel 856.

Display panel 1110, display space 1120, and background setting 1112 may be embodiments of display panel 110, display space 120, and background setting 112, respectively, which were discussed in conjunction with FIG. 1.
FIG. 11 shows a top view of display system 1100 that includes one flat display panel 1110 that is installed in parallel with and/or in front of background setting 1112 of the environment where the display system 1100 is installed. In at least one embodiment, display space 1120 is between display panel 1110 and background setting 1112. In at least one embodiment, the width and height of display space 1120 is limited by the size of the display panel 1110. In at least one embodiment, the viewer is on the side of display panel 1110 opposite the background setting 1112. In at least one embodiment, the width of display space 1120 is limited by the width of display panel 1120 and an angle β, which is the maximum angle at which the display item 111 can be viewed through display panel 1110 by a viewer that is at a specific location. In at least one embodiment, the angle β is limited by the size of display panel 1110 (e.g., the smaller the display panel 1110, the smaller the angle β) and/or the distance between the viewer and the display panel 1110 (e.g., the closer the display panel 1110 toward the viewer, the larger the angle β). Additionally, if the display panel is constructed from a birefringent material sandwiched between two polarizers, the viewing angle is also constrained by the display panel itself (e.g., a twisted nematic liquid crystal display panel may have a maximum viewing angle of about 30 degrees, for example). In at least one embodiment, angle β also changes when the viewer changes from one location to another. In at least one embodiment, the depth of display space 1120 is limited by the environment where the display system 1100 is installed (e.g., the distance between the display panel 1110 and the background setting 1112).

When the user uses the sensors to drive the model of vehicle, motion module moves the vehicle model from the center bottom of display space, for example, upward slowly and/or in a slightly shaking manner to imitate the vehicle moving on a road. Meanwhile a video is played on the display panel showing the view of a driver on the road, with central portion of the display panel being transparent or semi-transparent so that the model of vehicle is visible to the user through the display panel. The video on the display panel may show names and photos of sights on either side of the road during the imitation of the tour or trip, while the user may press on the pressure sensor to control the speed of the model of vehicle (e.g., the faster the vehicle travels, the faster the video that shows the tour is played on display panel). The user may also turn the steering wheel having the tilt sensor to the left or right to imitate a left turn or a right turn to change to another road. When names and photos of sights and attractions are display on the display panel, the user may press the heat sensor or use the touch screen on the display panel to select which sight to go to. Based on the selection, the video on display panel shows the view of the vehicle turning into the sight and then turns opaque to play a video introducing the sight. When the display panel is opaque, the motion module moves the model of vehicle into a concealed space and moves models of people into display space. In at least one embodiment, concealed space stores multiple models of people in different dressing, which may be selected depending on which sight is selected by the user (e.g., models of people in casual clothes for tours in malls or cinemas in the city, models in sport wear for activities in sport fields, mountains, forests, rivers or lakes). Then display panel starts playing a video of the selected sight, while a portion of display panel turns transparent so that the models of people are visible to the users through display panel. Motion module may move the models of people according to the contents of video played on the display panel. Control module may further control lighting module to adjust brightness and light focus during the display. At the end of display of sightseeing or after the user selects to exit from the current display, display panel turns opaque temporarily to show a video or image, while the motion module moves models of people into concealed space and moves the model of vehicle from concealed space back into the display space. Then the video resumes the road trip and a portion of the display panel turns transparent to shows a view of the model of the vehicle.
