  • the two pairs of the rims 100 a can be classified into long rims and short rims, and each pair of the rims 100 a are parallel to each other.
  • the bracket 106 a of the hinge module 106 can be substantially parallel to the rims 100 a, and the rims 100 a are generally, but not limited to, the short rims and can be elastically changed according to the requirements of designing or limitations of manufacturing.
  • the length of the bracket 106 a of the hinge module 106 can be longer than half the length of one of the rims 100 a so as to increase the mounting stability between the hinge module 106 and the cover 110 .
  • the length of the bracket 106 a of the hinge module 106 becomes longer, the gluing area and range between the bracket 106 a and the cover 110 relatively increase, and thus the mounting stability between the bracket 106 a and the cover 110 can be increased.
  • the cover 110 is forced, the force can be transmitted to the hinge 108 via the bracket 106 a and the pivotal portion 106 b, so that the hinge 108 can rotate together with the cover 110 relative to an object.
  • the width of the portion of the bracket 106 a that is adjacent to the hinge 108 is very important. Because the portion of the bracket 106 a is the interface via which the force is transmitted from the cover 110 to the hinge 108 , the portion of the bracket 106 a bears larger force than other portions. If the width of the portion of the bracket 106 a is longer, the mounting capability of the bracket 106 a is also larger, so as to prevent the defeat that the hinge module 106 separates from the cover 110 during the operation of the hinge 108 .
  • the width of the bracket 106 a is directly proportional to a desired torque of the hinge 108 and the width of the bracket is approximately longer than 25 mm, wherein the width of the bracket 106 a is the width of the end of the bracket that is adjacent to the hinge 108 .
  • the desired torque of the hinge 108 is the minimum force that the hinge 108 is necessarily loaded during operation.
  • the cover 110 of the embodiment further includes a reinforcing plate 110 a.
  • the reinforcing plate 110 a of the cover 110 can be fixed to the inner side of the cover 110 , just like the hinge module 106 does.
  • the reinforcing plate 110 a can be substantially perpendicular to the bracket 106 a, but the configuration between the reinforcing plate 110 a and the bracket 106 a is not limited to this and can be elastically changed according to the requirements of designing or limitations of manufacturing.
  • the reinforcing plate 110 a of the display device 100 and the bracket 106 a of the hinge module 106 can also be connected to each other.
  • the reinforcing plate 110 a and the bracket 106 a can be integrally formed according to the requirements of product design and then fixed to the inner side of the cover 110 to reinforce the strength of the cover 110 .
  • the reinforcing plate 110 a that is fixed to the cover 110 can be, but not limited to, made from an aluminum plate of which the thickness is 0.6 mm.
  • the display device 100 of the invention can be connected to the host housing by the hinge 108 , so as to make the display device 100 to rotate relative to the host housing.
  • the reinforcing plate 100 a on the cover 110 of the display device 100 will correspond to the palm raise of the host housing, so as to increase the supporting strength between the display device 100 and the host housing and prevent the display device 100 or the host housing from being damaged because users press improper locations.
  • the structures of the invention are applied to a display device that does not have backlight.
  • the display device of the embodiment can achieve the effect of evenly emitting light without the backlight module.
  • the display device that does not have backlight is an OLED (Organic Light-Emitting Diode) display device
  • the organic light-emitting layer is generally packaged in the glass module 130 in FIG. 4 to substitute for the liquid crystal layer 137 . Therefore, the panel module only includes the glass module 130 , and the supporting member on the frame 120 can support the panel module just by one supporting portion. When the panel module is fixed to the supporting portion of the frame 120 , the frame 120 will be the only one structure that supports the panel module.
  • the invention make a panel module and a frame to be fixed to each other to form a display module, so the frame is the only structure that supports the frame.
  • a cover is mounted to the frame to form a display device.
  • the cover includes a hinge module, and the hinge module can be fixed to the cover and connects a hinge, so that the hinge can connect the display device and a host housing to each other. Because the hinge module is fixed to the cover, the thickness of the display device can be greatly reduced, and the mounting strength of the display device against the rotation of the hinge can be maintained.
  • the display module is also mounted to the cover without screws, so the cover does not need to provide space to be fastened by screws so as to have a thinner thickness and the display module does not need to be formed screw holes so as to have a larger display region.
