图5A是图1A的可挠式显示设备的局部剖视图。图5B是图2的可挠式显示设备的局部剖视图。图6是图3的可挠式显示设备的部分构件示意图。如图4C、图5A与图5B所示，支撑链板150的一端部1502与可挠屏幕140的第二端140b固定于框架130。如图5A与图5B所示，支撑链板150的另一端1501固定于第一壳体110的第一子壳体111。FIG. 5A is a partial cross-sectional view of the flexible display device of FIG. 1A . FIG. 5B is a partial cross-sectional view of the flexible display device of FIG. 2 . FIG. 6 is a schematic diagram of some components of the flexible display device of FIG. 3 . As shown in FIG. 4C , FIG. 5A and FIG. 5B , one end 1502 of the supporting link plate 150 and the second end 140 b of the flexible screen 140 are fixed to the frame 130 . As shown in FIG. 5A and FIG. 5B , the other end 1501 of the support link plate 150 is fixed to the first sub-housing 111 of the first housing 110 .

此外，请参考图3，在本实施例中，第二壳体120包括支撑杆123，支撑杆123垂直于齿条R1。如图5A与图5B所示，支撑杆123位于可挠屏幕140与支撑链板150之间。第一显示区141与第二显示区142位于可挠屏幕140的外表面，支撑杆123抵接于可挠屏幕140的内表面。In addition, please refer to FIG. 3 , in this embodiment, the second housing 120 includes a support rod 123 , and the support rod 123 is perpendicular to the rack R1 . As shown in FIG. 5A and FIG. 5B , the support rod 123 is located between the flexible screen 140 and the support link plate 150 . The first display area 141 and the second display area 142 are located on the outer surface of the flexible screen 140 , and the support rod 123 abuts on the inner surface of the flexible screen 140 .

Abutment relationship between surfaces.

这样设计的好处在于，支撑杆123可以避免可挠屏幕140在第二壳体120的所述收合过程中因行程差而产生挤压或皱折等不良状态，其中行程差是指在收合过程中，由于齿轮G1与齿条R1、R2的间隙，所以在微观上，可挠屏幕140的收合行程会落后第二壳体120的收合行程。一如前述，可挠屏幕140的可挠特性会因其不同状态而产生形状、尺寸的变化。为了让装置机构(例如第一壳体110与第二壳体120)的机构行程能与可挠屏幕140的变形量得以相符，本实施例通过提供可相对移动的第一壳体110与第二壳体120，且通过支撑杆123搭配轴承124、弹簧160用以支撑可挠屏幕140，以让可挠屏幕140因张力而被拉紧而达到所需。The advantage of this design is that the support rod 123 can prevent the flexible screen 140 from being squeezed or wrinkled due to the stroke difference during the folding process of the second housing 120, wherein the stroke difference refers to the folding During the process, due to the gaps between the gear G1 and the racks R1 and R2 , microscopically, the retracting stroke of the flexible screen 140 will lag behind the retracting stroke of the second housing 120 . As mentioned above, the flexible characteristics of the flexible screen 140 may change in shape and size due to different states. In order to make the mechanism stroke of the device mechanism (eg, the first casing 110 and the second casing 120 ) match the deformation amount of the flexible screen 140 , in this embodiment, the first casing 110 and the second casing 110 and the second casing that can move relatively are provided in this embodiment. The casing 120 is used to support the flexible screen 140 through the support rod 123, the bearing 124, and the spring 160, so that the flexible screen 140 can be stretched by tension to achieve the desired purpose.

图7A与图7B分别是本发明的一实施例的可携式电子装置于不同状态的立体图。在本实施例中，可携式电子装置10包括主机200以及所述可挠式显示设备100。可挠式显示设备100通过枢接部T1以枢接于主机200且适于相对于主机200展开或闭合。当可挠式显示设备100相对于主机200展开时，第二壳体120适于相对于第一壳体110滑动而在所述抽出状态与所述收合状态之间转换。7A and 7B are perspective views of the portable electronic device in different states according to an embodiment of the present invention, respectively. In this embodiment, the portable electronic device 10 includes a host 200 and the flexible display device 100 . The flexible display device 100 is pivotally connected to the host 200 through the pivot portion T1 and is suitable for unfolding or closing relative to the host 200 . When the flexible display device 100 is unfolded relative to the host 200 , the second casing 120 is adapted to slide relative to the first casing 110 to switch between the drawn-out state and the retracted state.

综上所述，在本发明中，可挠式显示设备对应于可挠屏幕的可挠特性而设置能对应的第一壳体、第二壳体、框架，通过第二壳体相对于第一壳体滑动而在抽出状态与收合状态之间转换的过程中，第二显示区收于第一壳体与第二壳体内，或是展开摊平第二显示区，据以可以在抽出时以较大面积显示，又可以根据需要收合以利于携带或减少其所占用的空间。To sum up, in the present invention, the flexible display device is provided with a corresponding first casing, a second casing, and a frame corresponding to the flexible characteristics of the flexible screen. When the casing slides and switches between the withdrawn state and the folded state, the second display area is retracted into the first casing and the second casing, or the second display area is unfolded and flattened, so that the second display area can be pulled out. It is displayed in a larger area, and can be folded as needed to facilitate carrying or reduce the space occupied by it.

由于可挠屏幕能受到第二壳体的边框由上而下的压制及局限，所以在第二壳体的抽出过程中，可挠屏幕只需朝单方向展开。在其他实施例中，可挠式显示设备可朝左右方向拉开而得到更大的显示画面。一如前述，可挠屏幕的可挠特性会因其不同状态而产生形状、尺寸的变化。为了让装置机构(例如第一壳体与第二壳体)的机构行程能与可挠屏幕的变形量得以相符，本发明通过提供可相对移动的第一壳体与第二壳体并配合框架而达到所需。Since the flexible screen can be pressed and limited by the frame of the second casing from top to bottom, the flexible screen only needs to be unfolded in one direction during the extraction process of the second casing. In other embodiments, the flexible display device can be pulled apart in the left and right directions to obtain a larger display screen. As mentioned above, the flexible characteristics of the flexible screen will change its shape and size due to its different states. In order to make the mechanism stroke of the device mechanism (such as the first casing and the second casing) match the deformation amount of the flexible screen, the present invention provides a relatively movable first casing and a second casing and cooperates with the frame to achieve the desired.
