[0002] With the accelerated pace of life, people are pursuing higher efficiency in their daily work. Taking the laptop used at work as an example, in some work scenarios, the laptop needs to expand a larger display screen to complete the work more efficiently and conveniently. Therefore, in addition to the traditional display screen in the laptop, the design of the second display screen came into being. There are two existing dual-screen laptop design structures. One is to design a secondary screen on the system side of the laptop. However, due to the angle between the viewing angle of the screen and the normally used screen, the user has a large viewing angle difference when using it, which can easily lead to visual fatigue and poor user experience. The other is to design the laptop as a folding screen structure, and the system side of the laptop is a full screen. Although it can be used as a secondary screen, it also has a poor viewing angle, which causes visual fatigue to the user, reduces the experience, and is costly. In addition, since the traditional physical keyboard is cancelled, it is not convenient for users to operate. Utility Model Content

DETAILED DESCRIPTION

[0035] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0036] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0037] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Fig. 9As shown, a display device of an exemplary embodiment of the present disclosure includes a main body 1, a first display structure 2 and a second display structure 3, the main body 1 has a control component, the first display structure 2 is rotatably connected to the main body 1, the first display structure 2 includes a first display component 21, the first display component 21 is provided with a first soft board 22, the first soft board 22 includes a first connection end 221 and a touch portion 2231, and the first connection end 221 is connected to the control component; the second display structure 3 is slidably connected to the first display structure 2, the second display structure 3 includes a second display component 31 and a control portion 330, and the second display component 31 is electrically connected to the control component through the second soft board 32. Among them, the second display structure 3 has an initial position and a terminal position relative to the first display structure 2, and the first display component 21 has a closed state and a working state. When the second display structure 3 is located at the initial position, the control portion 330 is separated from the touch portion 2231, and the first display component 21 is in a closed state; when the second display structure 3 is located at the terminal position, the control portion 330 is in contact with the touch portion 2231, and the first display component 21 is in a working state.

[0038] In this embodiment, the display device may be a device or equipment having a display screen or serving as a prompt, including but not limited to a laptop computer, a desktop computer display, a control unit of a machine tool, or an electronic signboard. In the embodiments shown in the present disclosure, the display device is a laptop computer as an example. The main body 1 is the end where the input device, system, and processor of the laptop computer are located. The control component may specifically include but not limited to a printed circuit board (PCB) or a digital signal processing (DSP) chip. The second display component 31 serves as the main screen of the display device, and the first display component 21 serves as the secondary screen of the display device. Since the second display component 31 is always electrically connected to the control component through the second flexible board 32, the second display component 31 can continue to operate. The first display component 21 is provided with a first soft board 22, the first soft board 22 includes a touch portion 2231 and a first connection end 221 connected to the control component, the position of the first soft board 22 relative to the first display component 21 remains unchanged, since the position of the second display structure 3 is adjustable, the second display structure 3 includes a control portion 330, when the second display structure 3 slides to the end position, the control portion 330 can be in contact and communicate with the touch portion 2231 of the first soft board 22, so that the first display component 21 is in a working state, at which time the first display component 21 is fully exposed; if the second display structure 3 slides from the end position to the initial position, when the control portion 330 is separated and disconnected from the touch portion 2231 of the first soft board 22, the first display component 21 is in a closed state and stops running, and at this time only the second display component 31 is running. It can be understood that the touch portion 2231 on the first soft board 22 can be a contact point or a strip touch portion 2231. When the touch portion 2231 is a strip, the control unit 330 starts to contact the strip touch portion 2231 and the first display component 21 starts to operate, that is, the first display component 21 can start to operate when the second display structure 3 has not reached the end position, until the second display structure 3 reaches the end position, the first display component 21 is fully exposed and keeps the running state; similarly, the second display structure 3 starts to slide from the end position to the initial position, and the second display structure 3 leaves the end position. During the sliding of the control unit 330 along the strip touch portion 2231, the first display component 21 is in a working state but the exposed area gradually decreases until the control unit 330 is separated and disconnected from the strip touch portion 2231 of the first soft board 22, and the first display component 21 is converted to a closed state. As a result, the display device realizes screen expansion, is easy to operate, and has a simple structure, which can meet the user's needs for more efficient and convenient use and improve the user's experience.
