DETAILED DESCRIPTION OF THE INVENTION
First Embodiment
Referring to both FIG. 2A and FIG. 2B, FIG. 2A is a perspective view of a standing display device, while FIG. 2B is a perspective view of a laid-flat display device. The display device 200 includes a display panel 201 and a supporting structure 202. The display panel 201 and the supporting structure 202 are rotatably connected via a rotation device 250. Examples of the rotation device 250 include a spindle. As shown in FIG. 2B, the supporting frame 203 can rotate with respect to an axis A1. When a user would like to detach the base 205, the display panel 201 can be placed on a desktop and face downwards. By pressing the button 215 as well as the first protrusion 235a and the second protrusion 235b on the base 205, the user can detach the base 205 safely. The supporting structure 202 includes a first body and a second body. Examples of the first body include a supporting frame 203. Examples of the second body include a base 205. The first body has a releasing part and an anti-sliding part 218 (illustrated in FIG. 2C). Examples of the releasing part include a button 215.
Referring to both FIG. 2C and FIG. 2D, FIG. is a perspective view of the bottom of a supporting frame, and FIG. 2D is a partial enlarged view of the supporting frame in FIG. 2C. The first body (the supporting frame 203) has a releasing structure 211. The releasing structure 211 is fixed on the bottom of the supporting frame 203 via a fastening hole 241 and a positioning hole 243. The way of fixing the releasing structure is not limited. For example, the releasing structure 211 may be fixed by a screw. The releasing structure 211 has a body 213 and a button 215. The body 213 has an opening 219 for providing a pressing space to the button 215. The anti-sliding part 218 is a ramp, and an inserting part 220 is adjacent to the anti-sliding part 218.
Referring to both FIG. 2E and FIG. 2F, FIG. 2E is a perspective view of the inner side surface of the base, while FIG. 2F is a partial enlarged view of the inner side surface of the base in FIG. 2E. The second body (the base 205) includes a first fastening part 216 and a second fastening part 235. The second fastening part 235 includes a first protrusion 235a and a second protrusion 235b. In FIG. 2E, there is an inner side surface 233 of the base 205 via which the base 205 is engaged with the releasing structure 211. The base 205 has a base opening 231 for receiving the button 215, such that the user can press the button 215. A first protrusion 235a and a second protrusion 235b are adjacent to the two sides of the base opening 231. The relative relationship between the releasing structure and the base and how the releasing structure and the base are engaged are disclosed below.
Referring to both FIG. 3A and FIG. 3B, FIG. 3A is a cross-sectional view of a supporting structure when the releasing part is positioned at a first position. FIG. 3B is a cross-sectional view of a supporting structure when the releasing part is positioned at a second position. Under the normal state as shown in FIG. 2B, when the base 205 is assembled with the supporting frame 203, the protruding part 239 of the button 215 is engaged with the first fastening part 216 of the base 205. The button 215 has a recess 215a whose width is substantially equal to the thickness of the base 205. The button 215 resists the first fastening part 216 of the base 205 by the recess 215a for preventing the base 205 from sliding towards the first direction (the gravitational direction g). When the user would like to detach the base 205, the user, first of all, presses the button 215 to move towards a second direction A2. The button 215 is shifted along the direction A2, such that the recess 215a is detached from the base 205. The base 205 slides along a gravitational direction g (the first direction) by gravity until the first protrusion 235a and the second protrusion 235b (illustrated in FIG. 2E) fasten the anti-sliding part 218. The first direction is substantially perpendicular to the second direction. When the base 205 moves along the course S1 by its gravity, the base 205 does not come off directly, hence assuring the security of the user. The anti-sliding part 218 is a ramp. The first protrusion 235a and the second protrusion 235b also have a ramp, such as a ramp 235a1 for instance. The slope of the ramp of the anti-sliding part 218 is substantially equal to the slope of the ramp 235a1 of the first protrusion 235a and the second protrusion 235b, such that the anti-sliding part 218 is more tightly engaged with the first protrusion 235a and the second protrusion 235b. 
When the user would like to detach the base 205 from the releasing structure 211, the user has to overcome the friction between the anti-sliding part 218 and the first protrusion 235a and the second protrusion 235b. Thus the user has to pull the base 205 heavily. The releasing structure 211 is a plastic piece and has elasticity, such that the anti-sliding part 218 can be deformed for enabling the first protrusion 235a and the second protrusion 235b to be released from the anti-sliding part 218. The user can grip and detach the base 205. The function of the anti-sliding part 218 is to force the user to grip and detach the base 205 during the last course of movement, that is, the course S2. Consequently, the base 205 will not come off by its gravity which may cause accident to the user or cause damage to the base.
In the present embodiment of the invention, the base 205 is an iron piece and the releasing structure 211 is a plastic piece. The releasing structure 211 can be made from any suitable materials. The button 215 and the body 213 can be made by different materials as long as the button 215 and the anti-sliding part 218 of the body 213 have elasticity. Meanwhile, referring to FIG. 2D, a deformed opening 224 is adjacent to the anti-sliding part 218 for providing the anti-sliding part 218 with a deformation space when the user overcomes the resistance of the first protrusion 235a and the second protrusion 235b. 
Referring to FIG. 3A and FIG. 3B, on the body 213, an inserting part 220 adjacent to the anti-sliding part 218 is a ramp. The slope of the ramp of the inserting part 220 is smaller than the slop of the ramp of the anti-sliding part 218. The slope of the ramp 235a2 of the first protrusion 235a is also smaller than the slope of the ramp 235a1. Thus, when inserting the base 205 to be fixed on the releasing structure 211, the user will be able to overcome the friction between the first protrusion 235a and the releasing structure 211 by pushing the base 205 lightly, and the base 205 will be pushed to the position at which the protruding part 239 of the button 215 is engaged with the base 205.
Second Embodiment
In the first embodiment, the first body is a supporting frame and the second body is a base. However, in the second embodiment, the first body can be a base and the second body can be a supporting frame. Referring to FIG. 4, a cross-sectional view of a supporting structure when the releasing part of a second embodiment is positioned at a first position is shown. In the supporting structure 302, the first body is a supporting frame 303, and the second body is a base 305. In the second embodiment, the base 305 moves along a gravitational direction, and the way of fastening is reverse to that in the first embodiment. That is, the base 305 has a releasing part and an anti-sliding part 318, while the supporting frame 303 has a first fastening part 316 and a second fastening part 335, such that engaging the base in two stages is achieved.
According to the display device and the base of the same disclosed in the above embodiments of the invention, the two-stage design forces the user to grip the base when detaching the base after the first course. Thus, the user is able to perceive the current position of the base and the base will not slide and come off the body incidentally which may occur if the user presses and slides the base without knowing the current position of the base. Consequently, the accident which may otherwise occur to the user and the damage which may otherwise occur to the base are avoided.
While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
