As shown in fig. 2, the driving circuit board 22 is electrically connected to the display section 21 for supplying a driving signal to the display section 21. In some embodiments, the second body 20 has a plate-shaped structure, and the driving circuit board 22 and the display part 21 do not overlap in a thickness direction of the display part 21, so that the thickness of the second body 20 is reduced. However, this results in a larger frame width of the second body 20. On the other hand, if the driving circuit board 22 is folded to the backlight side of the display portion 21, the frame width of the second body 20 may be reduced, but the thickness of the second body 20 may be increased.

The disclosed embodiments provide a display device having a closed state and an open state. For example, the display device is a notebook computer. Fig. 3 is a top view of a display device provided in some embodiments of the present disclosure in a closed state, fig. 4A is a cross-sectional view taken along a direction AA' in fig. 3, and fig. 4B is an enlarged view of a region Q in fig. 4A, as shown in fig. 3 to 4B, the display device including: a first body 10 and a second body 20.

The first body 10 is a plate-shaped structure having a first surface S1 and a second surface S2 opposite to each other, and a side surface S3 connected between the first surface S1 and the second surface S2. The first surface S1 and the second surface S2 are respectively located at both sides of the first body 10 in the thickness direction thereof. The first body 10 may include: the system comprises a first shell, a system mainboard arranged in the first shell and an input structure.

The second body 20 is configured to be turned around the axis of the rotating member 40 relative to the first body 10, so that the display device is switched between a closed state and an open state. For example, the rotation member 40 includes a hinge, and the axis of the rotation member 40 is the axis of the rotation shaft in the hinge. The number of the rotating members 40 may be one or more, and in some examples, the number of the rotating members 40 is more than one, so that the overturning process of the second body 20 is more stable. For example, the number of the rotating members 40 is two. The axes of the plurality of rotating members 40 are positioned on the same straight line.

Fig. 4A is a schematic view of a display device in a closed state, fig. 6 is a schematic view of the display device provided in some embodiments of the present disclosure in an open state, and as shown in fig. 4A to 6, the closed state refers to a state in which the display portion 21 is overlapped with the first body 10; that is, the display unit 21 is located on the side of the first surface S1 of the first body 10 away from the second surface S2, and the thickness direction of the display unit 21 is substantially the same as the thickness direction of the first body 10, for example, the angle between the thickness direction of the display unit 21 and the thickness direction of the first body 10 is [0 °, 20 ° ], and for example, the thickness direction of the display unit 21 and the thickness direction of the first body 10 are both the second direction in fig. 4A. . The open state means that an angle between the thickness direction of the display part 21 and the thickness direction of the first body 10 is greater than a preset value, for example, 20 °, or 30 °, or 40 °, or 50 °, or 60 °.

In addition, in the embodiment of the disclosure, the second body 20 has a bent structure, and when the display device is in the closed state, as shown in fig. 4A, the display portion 21 is located on a side of the first surface S1 of the first body 10, which is away from the second surface S2, and at least a portion of the driving portion 22 is disposed opposite to the side surface S3 of the first body 10.

In the embodiment of the present disclosure, the second body 20 is of a bent structure, and the driving portion 22 is bent to the side surface S3 of the first body 10, in this case, when the display device is in an open state, and when a user views a picture displayed by the display portion 21, the width of the driving portion 22 viewed by the user is smaller, which is equivalent to reducing the width of the frame of the second body 20, and increasing the screen occupation ratio. Since at least a portion of the driving portion 22 is opposite to the side surface S3 of the first body 10, the bending of the second body 20 has little or no influence on the thickness of the display device. Therefore, the display device of the embodiment of the disclosure can improve the screen occupation ratio of the display device while preventing the increase of the thickness.
