In FIG. 7, receiving device 108 may include an opening 119, from which joining piece 110 may be attached to or detached from receiving device 108 (e.g., sliding groove). In this embodiment, joining piece 110 may not be able to attached to or detached from receiving device 108 from places other than opening 119, thereby enhancing the safety (e.g., preventing accidental dropping of display panel 106) in certain applications.
FIG. 8 illustrates detailed structure of the receiving holes 120 of FIG. 4. In FIG. 8, receiving hole 120 has a inner profile that is substantially matched to the outer profile of joining piece 110. For example, if joining piece 110 is a ball joint, receiving hole 120 may has a spherical shape that substantially conforms to the ball shape of joining piece 110. In another example, if joining piece 110 is a cylindrical joint, receiving hole 120 may also has a cylindrical shape that substantially conform is to the shape of joining piece 110. In some embodiments, receiving hole 120 may include an opening 122 that is slightly smaller than joining piece 110. To attach joining piece 110 to receiving hole 120, a user may apply force while placing joining piece 110 against opening 122 to cause deformation and temporary enlargement of opening 122. When joining piece 110 is pushed into receiving hole 120, opening 122 returns to its original shape and preventing joining piece 110 from dropping out of receiving hole 120. Additionally or alternatively, receiving hole 120 may include one or more elastic members 124 (e.g., similar to elastic member 118) to provide resistance to joining piece 110, as discussed above.
FIG. 9 illustrates a variation of the configuration shown in FIG. 4. In FIG. 9, display panel 106 includes an attachment 130 for gripping or holding one or more personal items 132 of a passenger. Personal item 132 may include a PDA, a tablet, a newspaper, a magazine, a book, etc. Attachment 130 may be flipped or moved to a storage position when it is not in use. Personal item 132 may interact with display panel 106 and exchange information or contents through Bluetooth, infrared, or other near-field wireless communication method. In addition, electric power may transfer from display panel 106 or receiving device 108 to recharge personal item 132 through port 114a, 114b, or other specific port (not shown). In some embodiments, the power may be transferred by physical connection. In some embodiments, the power may be transferred by wireless methods.
FIG. 10 illustrates another variation of the configuration shown in FIG. 4. In FIG. 10, panel-mount interface 112 is extendable to, for example, bring display panel 106 closer to a passenger. In some embodiments, panel-mount interface 112 may be bendable.
FIG. 11 illustrates an embodiment in which display panel 106 includes a second sliding groove 108a build onto the back of display panel 106. A second joining piece 110a may be provided to couple display panel 106 to panel-mount interface 112. The embodiment shown in FIG. 11 allows display panel 106 to move horizontally or vertically. The second sliding groove 108a may be placed near the top side of display panel 106, as shown in FIG. 11, or near the center or the bottom side of display panel 106. In some embodiments, the horizontal sliding groove may be placed on receiving device 108 at suitable positions. FIG. 12 illustrates an embodiment in which the second sliding groove 108a, the third sliding groove 108b, and the forth sliding groove 108c are placed on receiving device 108. Therefore, a wide range of positions can be approached in some specific applications. FIG. 13 illustrates an embodiment modified from FIG. 12, in which a plurality of receiving holes are used instead of sliding grooves.
In some embodiments, tray 104 may include input function, which can be a keyboard or a touch screen, and may work like a personal computer when integrated with display panel 106. In some embodiments, display panel 106 may be tilted to a horizontal position and be functioned as a tray with an enhanced position-locking mechanism (not shown). FIG. 14 illustrates a display panel having the tray function. Thus, tray 104 may be omitted.
In some embodiments, display panel 106 may include a wireless interface to provide display signals, control signals, power, and/or anti-theft detection to display panel 106 wirelessly.
