Hereinafter, some embodiments according to the present disclosure will be described with reference to
As shown in
In the above technical solution, the driving circuit board is disposed on the inclined surface X. Compared with a design of turning the driving circuit board to the back of the back plate, the thickness of the product may be reduced. In addition compared with a design of disposing the driving circuit board and the back plate on the same plane, the length of the product may be reduced, that is, the frame of the present application helps to reduce the overall size of the product, and when the first connecting portion is short and cannot be turned over to the back of the back plate, the inclined surface X is disposed to facilitate the mounting of the drive circuit board, and the driving circuit board disposed on the inclined surface X also facilitates the plugging and unplugging operations of other components with the connectors on the drive circuit board.
In some embodiments, an angle between the inclined surface X and a plane where the frame body 1 is located ranges from 10° to 30°. In other words, the angle between the inclined surface X and a surface of the frame body 1 supporting and mounting the first body portion ranges from 10° to 30°. “A plane where the frame body 1 is located” is a plane parallel to the surface of the frame body 1 supporting and mounting the first main body portion and the aforementioned liquid crystal display panel mounted on the frame body 1. In this way, the size of the product may be smaller, and the plugging and unplugging operations of other components with the connectors on the drive circuit board are facilitated.
In order to facilitate the positioning and mounting of the first body portion of the first component, as shown in
In addition, in some embodiments, the first end surface D1 is provided with a second annular step H2 for mounting a second body portion of a second component, and the second component may be a functional sheet of a touch screen. As shown in
In addition, in some embodiments, the first end surface D1 is provided with a third annular step H3 for mounting a third component, and the third component may be a cover plate of the touch screen. The third annular step H3 is disposed around an outside of the second annular step H2, and includes a third side wall H31 and a third supporting surface H32 connected to the third side wall and for supporting the third component, and an inner peripheral edge of the third supporting surface H32 away from the third side wall H31 is connected to an end of the second side wall H21 away from the second supporting surface H22. At this time, the first supporting surface H12, the second supporting surface H22, and the third supporting surface H32 are parts of the first end surface D1. In other words, the first end surface D1 includes at least the first supporting surface H12, the second supporting surface H22, and the third supporting surface H32. In this way, the third component may be stacked and disposed on the second component through the third annular step H3 to ensure smooth assembling.
