DESCRIPTION OF SOME EMBODIMENTS FIGS. 3A and 3B are schematic drawings showing a structure of a folding mobile according to an embodiment of the present invention. FIG. 4 is a schematic cross-sectional view of an internal structure of a display sheathing in a folding mobile phone according to an embodiment of the present invention. Referring to FIGS. 3A, 3B and 4, the folding mobile phone 200 comprises a main body 210, a display sheathing 220 and a pivot 240. Wherein, the main body comprises a button panel 212, and the display sheathing 220 pivots on the main body 210 through the pivot 240. The display sheathing 220 comprises a first surface 222 and a second surface 224 corresponding thereto. The first surface 222 is near the main body 210, and the second surface 224 is away from the main body 210. In the folding mobile phone 200, the internal part of the display sheathing 220 comprises a liquid crystal module 226, a light source 228 and a light-guiding bar 232. Wherein, a first light-guiding plate 234 a and a second light-guiding plate 234 b correspond thereto are disposed over two surfaces of the liquid crystal module 226, respectively. The first surface 222 exposes a portion of the first light-guiding plate 234 a, and the second surface 224 exposes a portion of the second light-guiding plate 234 b. In detail, the display window 222 a of the first surface 222 exposes a portion of the first light-guiding plate 234 a, and the display window 224 a of the second surface 224 exposes a portion of the second light-guiding plate 234 b. In addition, the light source 228 can be, for example, a light emitting diode or a cold cathode fluorescent tube which is disposed at a side of the liquid crystal module 226. The light-guiding bar 232 is disposed between the light source 228 and the liquid crystal module 226. The pivot 240 is connected with the light-guiding bar 232 so that the light-guiding bar 232 can move with the display sheathing 220. When the display sheathing 220 is opened or closed, the light-guiding bar 232 swings to either the first light-guiding plate 234 a or the second light-guiding plate 234 b, and thus guides light from the light source 228 to either the first light-guiding plate 234 a or the second light-guiding plate 234 b. The detailed movement of the light-guiding bar with the display sheathing 220 is discussed in the following. In an embodiment of the present invention, when the display sheathing 220 of the folding mobile phone 200 is opened as shown in FIG. 3A, the light-guiding bar swings to the second light-guiding plate 234 b. The light-guiding bar 232 then guides light 228 a to the second light-guiding plate 234 b. The second light-guiding plate 234 b guides the light 228 a to the liquid crystal display module 226. The liquid crystal module 226 transforms the light 228 a into images. Accordingly, when a user opens the display sheathing 220, the display window 228 a shows these images. In addition, when the display sheathing 220 is closed as shown in FIG. 3B, the light-guiding bar 232 swings to the first light-guiding plate 234 a. The light-guiding bar 232 guides light 228 a to the first light-guiding plate 234 a. The first light-guiding plate 234 a guides the light 228 a to the liquid crystal display module 226. The liquid crystal module 226 transforms the light 228 a into images. Accordingly, when a user closes the display sheathing 220, the display window 224 a shows these images. Note that the liquid crystal display module 226 in the present embodiment displays different images when the display sheathing 220 is opened or closed to perform the dual-display function. Accordingly, the display windows 222 a and 224 a show images with same sizes and same resolution and color saturation. FIGS. 5A-5C are configurations showing progression of a movement of a light-guiding bar with a display sheathing according to an embodiment of the present invention. Referring to FIGS. 5A-5C, the light-guiding bar 232 moves with the display sheathing 220 through a spring-plate module. The movement is discussed herein. Referring to FIG. 5A, the display sheathing 220 is opened. The spring-plate module 250 and the light-guiding bar 232 are near the second light-guiding plate 234 b as shown in FIG. 4. In FIG. 5A, the pivot 240 comprises a fixed sleeve 242 and a movable pivot 244. Wherein, the movable pivot 244 is connected with the display sheathing 220. The fixed sleeve 242 is connected with the main body 210. The fixed sleeve 242 comprises a protrusion part 242 a. In addition, the light-guiding bar 232 is connected with an end of the spring-plate module 250. Another end of the spring-plate module 250 contacts with the protrusion part 242 a of the fixed sleeve 242 while the display sheathing 220 opens and closes. The spring-plate module 250 comprises a rotation center 252, which enables the spring-plate module 250 to swing between the first light-guiding plate 234 a and the second light-guiding plate 234 b as shown in FIG. 4. As shown in FIG. 5B, during the closing process, the angle between the display sheathing 220 and the main body 210 is reduced. When the angle between the display sheathing 220 and the main body 210 is θ1, one end of the spring-plate module 250 is blocked by the protrusion part 242 a of the fixed sleeve 242. In this embodiment, θ1 can be 30� or other angles, such as 45� or 60�. As shown in FIG. 5C, because one end of the spring-plate module 250 is blocked by the protrusion part 242 a of the fixed sleeve 242, when the display sheathing keeps closing, the spring-plate module 250 swings near the first light-guiding plate 234 a as shown in FIG. 4. Since the light-guiding bar 232 is connected with the spring-plate module 250, the light-guiding bar 232 also swings near the first light-guiding plate 234 a. In contrary, when the angle between the display sheathing 220 and the main body 210 is more than 30�, the spring-plate module 250 swings near the second light-guiding plate 234 b. The light-guiding bar 232 also swings near the second light-guiding plate 234 b along with the swing movement of the spring-plate module 250, as shown in FIG. 4. FIG. 6 is a schematic drawing showing a structure for a movement of a light-guiding bar with a display sheathing according to an embodiment of the present invention. Referring to FIG. 6, the light-guiding bar 232 can also move with the display sheathing 220 through a cam device in this embodiment. In detail, the light-guiding bar 232 in FIG. 6 comprises an extrusion part 232 a. The end of the extrusion part 232 a comprises a roller 232 b. In addition, the fixed sleeve 242 comprises a cam shape 242 b. During opening or closing the display sheathing 220, when the roller 232 b passes the cam shape 242 b on the fixed sleeve 242, the roller 232 b rotates and promotes the light-guiding bar 232 to swing. In an embodiment of the present invention, while the roller 232 b passes the cam shape 242 b, the light-guiding bar 232 swings from the first light-guiding plate 234 a to the second light-guiding plate 234 b as shown in FIG. 4, or from the second light-guiding plate 234 b to the first light-guiding plate 234 a. The movement of the light-guiding bar 232 and the display sheathing 220 by using the cam device is similar to that described in the last embodiment. Detailed descriptions are not repeated. FIG. 7 is a schematic drawing showing a structure for a movement of a light-guiding bar with a display sheathing according to another embodiment of the present invention. Referring to FIG. 7, the light-guiding bar 232 can further move with the display sheathing 220 through a gear wheel in this embodiment. In detail, the light-guiding bar 232 in FIG. 7 comprises an extension part 232 a. The end of the extension part 232 a comprises a gear wheel 232 c. In addition, the fixed sleeve 242 comprises a saw-type protrusion 242 c operating in coordination with the gear wheel 232 c. During opening or closing the display sheathing 220, when the gear wheel 232 c passes the saw-type protrusion 242 c of the fixed sleeve 242, the gear wheel 232 c rotates and promotes the light-guiding bar 232 to swing. In this embodiment, while the gear wheel 232 c passes the saw-type protrusion part 242 c, the light-guiding bar 232 swings from the first light-guiding plate 234 a to the second light-guiding plate 234 b as shown in FIG. 4, or from the second light-guiding plate 234 b to the first light-guiding plate 234 a. The movement of the light-guiding bar 232 with the display sheathing 220 by using the gear wheel 242 c is similar to that described in the last embodiment. Detailed descriptions are not repeated. Note that the spring-plate module, cam device, and the gear wheel apparatus are exemplary in the present invention. Other apparatus serving the same function may also be used in the present invention. Therefore, the present invention is not limited thereto. The movement of the light-guiding bar with the display sheathing can be performed by using not only the spring-plate module, extrusion-rolling apparatus, and the gear apparatus, but other apparatuses suitable for serving the same function. Accordingly, the folding mobile phone of the present invention uses a double-sided liquid crystal display panel so that these two surfaces will alternatively display images when the display sheathing is opened or closed. Not only will the manufacturing costs be reduced, but these surfaces of the display sheathing have the same dimension, resolution and color saturation. In addition, the folding mobile phone of the present invention uses a pivot for connecting the main body and the display sheathing and for activating the light-guiding bar to swing between two light-guiding plates, and thereby serving the double-sided display function. Accordingly, the folding mobile phone of the present invention requires only one light source to perform the double-sided display function in the liquid crystal module. The manufacturing costs can thus be reduced. In addition, only one liquid crystal module is disposed in the display sheathing. The thickness of the display sheathing can also be reduced. Although the present invention has been described in terms of exemplary embodiments, it is not limited thereto. Rather, the appended claims should be constructed broadly to include other variants and embodiments of the invention which may be made by those skilled in the field of this art without departing from the scope and range of equivalents of the invention.
