       DETAILED DESCRIPTION 
       [0038]    In the following description, the portable desktop computer of embodiments of the present application will be described in detail with reference to the drawings. 
         [0039]    A portable desktop computer, as shown in  FIG. 1  and  FIG. 2 , comprises a columnar host  1  and a flexible display  2 . The columnar outer surface of the host  1  is provided with a ring groove  101  into which the flexible display  2  can be wound, and block pins are provided between the host  1  and the flexible display  2  for blocking the flexible display  2  into the ring groove  101 . 
         [0040]    In the present embodiment, since the host  1  is disposed as a columnar structure the columnar outer surface of which is provided with the ring groove  101 , and the display  2  is disposed as a flexible structure which can be curved, e.g., the flexible display screen is carried on a flexible metal sheet (which, for example, could be a metal sheet which can be curved and have the shape-memory effect), the flexible display  2  can be wound into the ring groove  101  and blocked within the ring groove  101  via the block pins, thereby integrating the host  1  with the flexible display  2  for convenient carrying and transportation. 
         [0041]    In use of the portable desktop computer, as shown in  FIG. 1 , where the blocking effect of the block pins to the flexible display  2  is released, the flexible display  2  is gradually unfolded from the ring groove  101 . After being unfolded, one end of the flexible display  2  can be blocked via the block pins and remained connected with the host. Since the flexible substrate of the flexible display  2  is a metal sheet which can be curved, the unfolding extent of the flexible display  2  can be adjusted, and when the display  2  is adjusted for a proper viewing angle, the display  2  can be supported by a frame or other means for positioning it and then be operated. This has the advantages of wide viewing angle, simple structure and easy use. Furthermore, in this operating state, the flexible display  2  may be directly fixed at the host  1  without any means for supporting and fastening the flexible display  2  (e.g., the base for the display), thereby not only saving material and reducing cost, but also saving space and time for installing the display, and thus it is very easy to use the desktop computer since only the data connection between the host  1  and the flexible display  2  and power supply are needed. The flexible display  2  can be powered by external power supply lines or the host. 
         [0042]    As shown in  FIG. 1 , when the flexible display  2  is unfolded for use, it can be remained connected with the host at its one end by which the power supply and signal transmission between the flexible display  2  and the host  1  can be attained, so that the step of providing additional connection to the flexible display  2  can be omitted. As another example, as shown in Fig. 7 , in operation, the flexible display  2  can be disposed separately from the host  1 , which would have higher flexibility to use. 
         [0043]    Moreover, as shown in  FIGS. 1 and 3 , after the flexible display is unfolded, it can be seen that a data line interface panel  105  for the host is provided at the bottom of the ring groove of the host  1  (i.e., the columnar surface of the host). In the panel, various interfaces are provided for the connection of the portable desktop computer with various periphery devices. 
         [0044]    When the portable desktop computer is not in use or is required to be moved to other relatively remote locations, as shown in  FIG. 2 , the flexible display  2  is merely needed to be rolled and wound within the ring groove  101  and then blocked via the block pins. At this time, the host  1  and the flexible display  2  are secured together and thus the whole desktop computer merely occupies the same space as that the host  1  alone occupies, so that the desktop computer can be packed as a whole, thereby saving the material and time for packing and resulting in easy carrying and transportation. 
         [0045]    In the present embodiment, as shown in  FIGS. 3 and 6 , the block pin is a retractable projection  102  for the purpose of simplifying the structure of the block pin. The projection  102  is provided at the edge position of two opposite ring surfaces of the ring groove  101 , e.g., the edge positions of the upper and lower ring surfaces of the ring groove  101  as shown in the drawings. The retracting of the projection  102  can be realized by providing an elastic means such as a spring between the projection  102  and the host. When the flexible display  2  needs to be rolled and wound into the ring groove  101 , the projection  102  is firstly pressed to release the blocking effect of the projection  102 ; and after the flexible display  2  has already been rolled and wound into the ring groove  101 , the projection  102  is rebounded by means of the action of the elastic means so that the flexible display  2  is limited in the space between the projection  102  and the periphery of the ring groove  101 . In addition, the block pin can be designed as other structures capable of blocking the flexible display  2 , such as rotary knob or roll-over block pin, omitting detailed descriptions thereof. For the purpose of enhancing the stability of the flexible display in the ring groove, a plurality of block pins can be evenly provided at the periphery of the ring groove. 
         [0046]    For the purpose of preventing the flexible display  2  from waggling within the ring groove  101 , the width of the ring groove  101  is substantially equal to the width of the flexible display  2 , and after being wound, the upper and lower sides of the flexible display  2  are just abutted against the upper and lower ring surfaces of the ring groove  101 . 
         [0047]    When the flexible display  2  is wound into the ring groove  101 , the minimum depth of the ring groove  101  is not less than the thickness of the flexible display  2  in order for fitting both well and pretty appearance. At this time, the flexible display  2  can be received as a whole in the holding space of the ring groove  101  so that the surface of the display screen will be not easily scratched during transportation and carrying. Of course, the flexible display  2  can be wound precisely one round within the ring groove  101  so that it will not overlap itself during winding, so that there will not be any depression, thereby not only maintaining the display quality of the flexible display  2 , but also maintaining the pretty appearance after it is wound. It is to be understood that the minimum depth of the ring groove  101  can be larger than the thickness of the flexible display  2  so that the flexible display  2  can be wound more than one round, so that further reduces the diameter of the host  1  and its volume and weight, for facilitating transportation and carrying. 
         [0048]    Because the Organic Light-Emitting Diode (OLED) is thin, it can be installed on the flexible material such as plastic or shape-memory metal sheet to form the flexible screen. Compared to the traditional screen, the flexible screen is lighter and thinner, capable of being curved and folded and consuming less power. Accordingly, for the purpose of thinning the display, increasing the view angle and saving electricity, the flexible OLED display screen of the flexible display  2  is carried on the metal sheet. 
         [0049]    In the present embodiment, as shown in Fig. 4 , for the purpose of fully making use of the structural feature of the host  1  and reducing the volume of the whole desktop computer, the host  1  is provided with a hollow cavity; 
         [0050]    and the hollow cavity is provided with a heat sink  107  which is integrated with a motherboard, a CPU, a sound card and a graphics card. Of course, it is well known in the art that the CPU, the sound card and the graphics card can be directly integrated into the motherboard. As shown in  FIGS. 1 to 4 , an air inlet  103  can be provided above the hollow cavity of the host  1  shown in the figure and an air outlet  104  can be provided below the hollow cavity. 
         [0051]    Moreover, for the purpose of increasing heat-dissipation area, as shown in  FIG. 5 , the heat sink  107  can be disposed as a hollow polygonal prismatic structure. Alternatively, the heat sink  107  can be disposed as a structure having multiple layers which nest each other. For example, the heat sink  107  is disposed as an inner layer of heat sink and a outer layer of heat sink, wherein the inner layer is a one-piece heat sink  109  and the outer layer is a cellular heat sink  108  (the cellular shape is not shown in the drawing). The one-piece heat sink  109  is provided with a motherboard, a CPU, a sound card and a graphics card etc. Particularly, components such as the motherboard etc can be embedded between the heat sinks. 
         [0052]    In the present embodiment, as shown in  FIG. 4 , for the purpose of further increasing heat-dissipation effect of the heat sink  107 , a fan  106  is provided above the heat sink which speeds up the air flow and in turn improving heat-dissipation. 
         [0053]    In the present embodiment, for the purpose of allowing for data connections between the host  1  and the flexible display  2 , the host  1  and the flexible display  2  each are provided with Video Graphics Array (VGA) interfaces, such as data line interfaces  105  for the host (as shown in  FIGS. 1 and 3 ), data line interfaces for the display  203  (as shown in Fig. 7 ). The host  1  and the flexible display  2  are connected via VGA data lines for data transmission. Apparently, the VGA interfaces can be replaced with DVI or HDMI interfaces. In addition, power line can be provided between the host  1  and the flexible display  2  for powering the flexible display  2  through the host  1 . 
         [0054]    In the present embodiment, in use of the flexible display  2 , a frame  201  of a certain shape can be used for supporting the flexible display for the purpose of unfolding the display screen to such an extent that the viewing angle is increased. For example, the frame  201  is disposed as a rod-shaped structure of a curved radian with which the upper and lower sides of the flexible display  2  are supported so that the flexible screen displays at a radian defined by the frame  201  to meet various display demands at different viewing angles. In addition, the frame  201  can be simply disposed as a straight rod, that is, the radian is zero, and therefore the flexible display screen is a plane display having the same displaying effect as the existing display screens. 
         [0055]    In the present embodiment, in use of the flexible display  2 , a base  202  can be provided for supporting the flexible display  2  in order to enhance the applicability of the portable desktop computer. As shown in  FIGS. 7 and 8 , the base  202  is provided with an angle adjusting arm  204  for adjusting the pitch angle of the flexible display  2  (the angle adjusting means) and a height adjusting arm  205  for adjusting the height of the flexible display  2  (the height adjusting means). With such arrangement, the flexible display  2  can be placed separately from the host  1  during its operation, the applicability of which is enhanced significantly. In addition, the pitch angle and height of the flexible display  2  can be adjusted as demanded. 
         [0056]    Particularly, the angle adjusting arm  204  spherically matches the base  202  so as to be adjustable at various azimuths. The height adjusting arm  205  is connected with the angle adjusting arm  204  and can be moved up and down along the angle adjusting arm  204  to achieve height adjusting. The specific structures and connections of the two adjusting arms are similar to those in the existing desktop computers and thereby the detailed descriptions are omitted herein. 
         [0057]    In the present embodiment, as shown Figs. 1  and  2 , for the purpose of reducing machining difficulties and cost, the columnar outer surface of the host can be instead designed as a cylindrical surface or other shapes, such as triangular prism, quadrilateral prism, pentagonal prism and hexagonal prism. Where the columnar outer surface of the host  1  is of polygonal prism, the ridges of the polygonal prism should be rounded so that the prismatic surface which contacts directly the flexible display  2  smoothly transits to prevent the ridges of the prism from grinding and scratching the display screen unnecessarily when the flexible display  2  is wound into the ring groove  101  of the host  1 . 
         [0058]    In the present embodiment, in addition to the above advantages, a columnar lamp can be achieved after winding the flexible display  2  into the ring groove  101  of the host  1 . At this time, the display face of the flexible display  2  should face outwards. When a power line is connected to the flexible display  2  and the flexible display  2  is turned on, the lighting effect can be achieved. This further enhances the functionality of the flexible display. 
         [0059]    In sum, the flexible display  2  is wound into the ring groove  101  of the host  1  so that the desktop computer has the advantages of easily carrying and convenient transportation. And the flexible display  2  can be supported by the frame  201  of a certain arc so that the viewing angle range of the flexible display  2  can be increased. It also can be used as a lamp where the flexible display  2  is wound into the ring groove  101  with its display face facing outwards. Accordingly, the desktop computer of such structure can not only improve the portability but also its functionalities.
