The specific sizes of the first back plate 11 and the second back plate 12 may be set according to actual requirements, and the embodiment of the present application is not limited.
It should be noted that, in the embodiment of the present application, the display panel 1 may actually be a flexible Organic Light-Emitting Diode (OLED) display panel 1, and an edge portion of the display panel may be bent, that is, include the bent frame 13. The bending frame 13 includes a bending side 131 and a bending corner 132, and for the bending side 131, even if it is expanded by a certain width, after bending, the user is difficult to visually perceive the change of the black border, and for the bending corner 132, the bending corner itself is located at the corner position, and the amount of bending is limited, and if it is expanded by the width, the user can visually and obviously perceive the change of the black border. Therefore, in the present application, in the case where the second driving circuit 134 is already disposed at the bent side corner 132 and the bent side 131, the first driving circuit 133 is disposed at the bent side 131, and the bent side 131 is expanded by a certain width.
