     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     To make the person skilled in the art better understand the technical solutions of the present invention, the present invention is further described below in detail in conjunction with the accompanying drawings and the specific embodiments. 
     First Embodiment 
     As shown in  FIGS. 2-7 , the embodiment provides a display device, including a display panel  1 , a supporting structure  9  for accommodating and fixing the display panel  1 , and a seat  4  disposed below the supporting structure  9 , wherein the supporting structure  9  is provided with an opening at a side opposite to the seat  4 , and the display panel  1  is allowed to be inserted into the supporting structure  9  through the opening of the supporting structure  9 , and the seat  4  is configured to lock the display panel into the supporting structure  9 . The A-A section in  FIG. 3  is shown for illustrating the opening of the supporting structure  9 , from which the display panel is inserted. 
     The display device of the embodiment integrates a front frame  2  and a back plate  3  of an existing display device into a whole to form the supporting structure  9  for accommodating and protecting the display panel  1 , without need to clamp and lock the front frame  2  and the back plate  3 . In this case, the integrated supporting structure  9  can achieve the functions of fixing and protecting the display panel  1 , etc., without needing additional outer front case  7  and outer back case  8 , thus making the display device lighter and thinner. 
     The display panel  1  of the display device of the embodiment includes a display surface and a back surface opposite to the display surface; as shown in  FIG. 3 , the supporting structure  9  includes a first surface  9 - 1  opposite to the display surface of the display panel, and a second surface  9 - 2  opposite to the back surface of the display panel; and preferably, the first surface  9 - 1  is provided with an opening at a position corresponding to a display area of the display surface of the display panel. Of course, if the first surface  9 - 1  is of a transparent structure, the first surface  9 - 1  does not need an opening. 
     Preferably, the display device of the embodiment further includes a signal plate  16  (shown in  FIG. 4 ), and the second surface  9 - 2  is provided with a first protrusion part  12  at a position close to the seat, that is, the first protrusion part  12  is located at the D-D position in  FIG. 3 , and the first protrusion part  12  is configured to accommodate the signal plate  16 . 
     It needs to be noted that, the upper and lower sides within the supporting structure  9  are not uniform in thickness, but a fixed distance is maintained between the inner surfaces of the first surface  9 - 1  and the second surface  9 - 2 , thus functioning to support two sides of the display panel  1 . The upper portion of the supporting structure  9  can be made very thin, as long as the thickness of the display panel can be received, that is, the C-C position as shown in  FIG. 3  is the thinnest position of the whole supporting structure  9 . 
     Preferably, the four corners at the opening of the supporting structure  9  are all rounded corners, that is, as shown in  FIG. 3 , the bottom feet at the lower ends of D-D and E-E are all rounded corners. In this case, the display panel  1  can be prevented from being scraped during insertion into the supporting structure  9 . Of course, also preferably, the display panel  1  includes a top side surface away from the seat  4 , and two lateral side surfaces connected with the top side surface, and protective adhesive tapes are adhered to the top side surface and the lateral side surfaces. This can also prevent the display panel  1  from being scraped during insertion into the supporting structure  9 . 
     As shown in  FIGS. 5-7 , preferably, the seat  4  of the embodiment includes a connecting part  10  connected with the supporting structure  9  and a base part  11  for supporting the connecting part  10 , wherein the connecting part  10  and the base part  11  are both of hollow structures. Further preferably, the base part  11  is made of a metal material. The display device of the embodiment further includes a circuit system  5  and a connecting line. In this case, further preferably, the circuit system  5  is disposed in the base part  11 , and as the base part  11  is made of a metal material, the base part can serve as an electromagnetic shielding cover  6  of the circuit system  5  to prevent external electromagnetic interference. It needs to be noted that, the base part  11  includes a bottom surface and an outer casing, wherein the outer casing and the bottom surface are locked to each other and provided with an accommodating space therebetween, that is, the circuit system  5  is arranged inside the base part  11 . The connecting line is arranged in the connecting part  10 , and the circuit system  5  is connected with the display panel  1  by the connecting line. 
     It needs to be noted that, the connecting part  10  and the base part  11  of the seat  4  may be an integrally formed structure, and in this case there is no connecting gap between the connecting part  10  and the base part  11 , so the seat  4  with this structure is firmer; of course, the connecting part  10  and the base part  11  of the seat  4  may also be separate structures connected to each other, and in this case the base part  11  can be made of a metal material, and the connecting part  10  is made of a plastic material, wherein the base part  11  of the metal material can serve as an electromagnetic shielding cover  6  of the circuit system  5 , and the connecting part  10  of the plastic material not only can make the whole structure of the display device lighter and thinner, but also can save cost. 
     As shown in  FIGS. 6 and 7 , in order to better support the display panel  1 , preferably, the connecting part  10  is provided with a second protrusion part  13  at a part connecting with the supporting structure  9 , and a silicone gasket  15  is arranged on the second protrusion part  13 . The second protrusion part  13  is provided with a screw hole  14  at a middle position, and of course the supporting structure  9  is provided with a corresponding round hole at a position corresponding to the second protrusion part  13 , so that the connecting part  10  and the supporting structure  9  are locked and fixed to each other through a screw passing through the round hole of the supporting structure and the screw hole  14  of the connecting part. 
     As shown in  FIG. 6 , preferably, the connecting part  10  is of a U-shaped structure, wherein the U-shaped structure is connected to the supporting structure at one side and connected to the base part  11  at the other side, and as the side of the U-shaped structure close to the supporting structure  9  is a force bearing side, preferably the wall thickness of the U-shaped structure at the side close to the supporting structure  9  is larger than that at the other side. In this case the thickness of the U-shaped structure is different at the two sides, which not only can ensure supporting ability of the U-shaped structure, but also can make the connecting part  10  lighter and convenient for use. 
     As an OLED display device does not need a backlight module, and is self-reflective, the display device of the embodiment is preferably an OLED display device, which is lighter and thinner and may have a narrower frame, thus being more practical. 
     It should be understood that the above embodiments are only exemplary embodiments for illustrating the principle of the present invention, however, the present invention is not limited thereto. Various modifications and improvements may be made by a person skilled in the art without departing from the spirit and essence of the present invention, and these modifications and improvements should also be considered to be within the protection scope of the present invention.
