Please refer to FIGS. 1A to 4 . FIG. 1A is a schematic diagram of the appearance of the first embodiment of the present invention, FIG. 1B is a schematic diagram of another view of FIG. 1A , and FIGS. 2A to 2B are schematic diagrams of the use of the first embodiment of the present invention (one ) and (2), FIG. 3 is a schematic exploded perspective view of the first embodiment of the present invention, and FIG. 4 is a schematic exploded perspective view of another perspective view of the first embodiment of the present invention. The present invention provides a display device 1 including a display panel 11 , a front back panel 12 , a back back panel 13 and a sliding member 14 .

The display panel 11 may mainly include a first display area 111 and a second display area 112 . In some implementations, the first display area 111 and the second display area 112 may display different images. For example, as shown in FIG. 1A , the first display area 111 and the second display area 112 The display area 111 displays a plurality of function keys arranged along the array. For example, as shown in FIG. 1B , the second display area 112 displays a plurality of push messages.

For another example, as shown in FIG. 2A , the first display area 111 displays the game screen, and the second display area 112 becomes an input unit through display, which can be, for example, a keyboard or a control button (such as direction keys, function keys for manipulating the movement of game characters) Wait).

In some embodiments, for example, as shown in FIG. 2B , the first display area 111 and the second display area 112 can jointly form a display area to display a full-screen image, which means that the full-screen image displayed together will be larger than that displayed by the display area alone. The picture displayed in the first display area 111 or the second display area 112 .

As shown in FIG. 2A , in some implementations, the display panel 11 may further include a non-display area 113 , and the non-display area 113 is not used for displaying images. Here, the non-display area 113 is preferably located in the first Between the display area 111 and the second display area 112 , the first display area 111 and the second display area 112 are connected.

In one embodiment, the area of the second display area 112 is smaller than the area of the inner surface 132 or the outer surface 131 of the back panel 13 . Therefore, when the display device 1 is in a stacked state, the second display area 112 only partially covers the back. The outer surface 131 of the board 13 (as shown in FIG. 1B and FIG. 5A ); when the display device 1 is in the unfolded state, the second display area 112 can roughly cover the inner surface 132 exposed by the back board 13 protruding from the front back board 12 (As shown in Figure 2A, Figure 5B). However, the present invention is not limited to this. In another embodiment, the area of the second display area 112 is substantially equal to the area of the inner surface 132 or the outer surface 131 of the back panel 13 . Therefore, the display device 1 is in a superimposed state. When the second display area 112 substantially covers the area of the inner surface 132 or the outer surface 131 of the back panel 13; when the display device 1 is in the unfolded state, the second display area 112 substantially covers the inner surface 132 of the back panel 13 (as shown in FIG. 11 ). Show).

Please refer to FIGS. 3 , 5A and 5B. FIG. 5A is a schematic cross-sectional view of the first embodiment of the present invention in a superimposed state, and FIG. 5B is a cross-sectional schematic view of the first embodiment of the present invention in an unfolded state. The front back panel 12 can support the display panel 11 . Further, the first display area 111 is positioned on the top surface 121 of the front back panel 12 . In addition, the display panel 11 can further include a circuit substrate 114 , which is preferably positioned on the front back panel 114 . between the board 12 and the first display area 111 . Here, regardless of whether the display device 1 is in a stacked state (as shown in FIGS. 1A and 5A ) or an unfolded state (as shown in FIGS. 2A and 5B ), the first display area 111 is located on the top surface 121 of the front back panel 12 .

Referring to FIGS. 2A , 3 and 4 , the rear panel 13 is located below the front panel 12 and overlaps with the front panel 12 .

[Fourth Embodiment]

Please refer to FIGS. 11 , 12A and 12B. FIG. 11 is a schematic diagram of the use of the fourth embodiment of the present invention. 12B is a partial cross-sectional schematic diagram of the fourth embodiment of the present invention in the unfolded state. In this embodiment, the same parts as those of the first embodiment to the third embodiment will be marked with the same component symbols, and the same components and structures will not be repeated.

In this embodiment, the front panel 12 may further include a front panel arc portion 123 , and the rear panel 13 may further include a rear panel arc portion 133 . 11 , 12A and 12B again, the front panel arc 123 is located on the side of the front panel 12 to connect the top surface 121 and the bottom surface 122 , and the rear panel arc 133 is located on the side of the rear panel 13 and The outer surface 131 and the inner surface 132 are connected.

12A and 12B, in this embodiment, the sliding member 14 is mainly composed of a guide rail 141 and a guide block 142, wherein a part of the guide rail 141 is located on the inner surface 132 of the back plate 13, and the other part is located on the inner surface 132 of the back plate 13. Located on the back panel arc 133, that is, the guide rail 141 extends from the inner surface 132 of the back panel 13 to the back panel arc 133; one end of the guide block 142 is pivotally connected to the back panel arc 133, and the other end is slidable is arranged in the guide rail 141.

When the guide block 142 slides along the guide rail 141, the guide block 142 is substantially perpendicular to the back plate 13, and can drive the front back plate 12 to move relative to the back plate 13; when the guide block 142 continues to move to the guide rail 141 of the back plate arc 133 , the guide block 142 is rotated to be substantially parallel to the rear panel 13 , and will drive the front panel arc 123 to move along the rear panel arc 133 . When the guide block 142 moves to the end 141 a of the guide rail 141 , the top surface 121 of the front panel 12 and the inner surface 132 of the rear panel 13 form a coplanar plane (as shown in FIGS. 11 and 12B ), and the second display area 112 The suction member 16 (the suction member 16 is shown in FIG. 3 ) is flatly attached to the inner surface 132 of the back panel 13 .

It should be noted that in this embodiment, the area of the second display area 112 is approximately equal to the area of the inner surface 132 or the outer surface 131 of the back panel 13 . Therefore, when the display device 1 is in a stacked state, the second display area 112 approximately covers the outer surface 131 of the back panel 13. When the display device 1 is in the unfolded state (ie, when the front panel 12 and the back panel 13 are coplanar), the second display area 112 may approximately cover the entire inner surface 132 of the back panel 13 ( as shown in Figure 11).

To sum up, the display device 1 disclosed in the present invention can be changed between the stacked state (as shown in FIG. 1A ) and the unfolded state (as shown in FIG. 2A ). The design of the sliding member 14 enables the connection of the entire mechanism The relationship is stable and not easily damaged during the transformation process. In addition, the first display area 111 and the second display area 112 can be used for display regardless of the overlapping state or the unfolding state. The difference is that the position of the second display area 112 is different in different states, and the second display area The display of the area 112 at different positions is also different. When the display device 1 is in the unfolded state, the first display area 111 and the second display area 112 can be merged into a larger display area, or the second display area 112 can be displayed through the display. It becomes an input unit, which can be, for example, a keyboard or a control button (such as direction keys, function keys, etc. for manipulating the movement of game characters), which is convenient for the user to view the first display area 111 while operating the input unit of the second display area 112 to control.

Although the technical content of the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person who is familiar with the art, makes some changes and modifications without departing from the spirit of the present invention, should be included in the present invention.
