In this way, the distance between the two limiting structures 19 can be increased, the number of limiting structures 19 can be reduced, and the overall structure can be simplified. In this structure, the connecting line s1 can pass through the plurality of limiting structures 19 in an s shape. Specifically, the connecting line s1 can first pass through the two limiting structures 19 on one support rod 152, then pass through one limiting structure at one end of an adjacent support rod 152 of the support rod 152, and then pass through one limiting structure 19 at the other end of the adjacent support rod 152, and so on, to pass through the plurality of limiting structures 19.

[0094] In an exemplary embodiment, the second device q2 is the controller 17, and the first device q1 includes at least one sensor. The sensor can be used to collect various data and transmit the data to the controller 17, so that the controller 17 controls the shaft motor assembly and the lead screw motor assembly based on the data.

[0095] Optionally, please refer to Figure 5 , the display device further includes a first sensor t1 electrically connected to the controller Figure 5 (not shown in the figure).

[0096] The first sensor t1 is located at the screen rotating shaft 12, and is configured to acquire the rotating angle of the screen rotating shaft 12. The controller can control the screen rotating shaft 12 based on the rotating angle of the screen rotating shaft 12 acquired by the first sensor t1, so as to achieve the effect of accurately controlling the rotating angle of the screen rotating shaft 12. In this way, when the flexible screen is pulled out of the screen rotating shaft 12 by the screw motor assembly, the rotating angle of the screen rotating shaft 12 can be accurately controlled to apply a pulling force, so as to offset the friction and rebound force in the movement of the flexible screen, thereby improving the flatness of the flexible screen and improving the user experience.

[0097] Optionally, the display device further comprises a second sensor, which is electrically connected to the controller.

[0098] The second sensor is located at the screw motor assembly, and is configured to acquire the rotating angle of the screw. Similar to the first sensor, the control assembly can acquire the rotating angle of the screw acquired by the second sensor, so as to achieve the effect of accurately controlling the rotating angle of the screen rotating shaft 12. For example, the control assembly can accurately control the length of the flexible screen pulled out by the screw motor assembly, so as to avoid the problem that the length of the flexible screen pulled out is too short and the flexible screen is not flat, and avoid the problem that the length of the flexible screen pulled out is too long and the flexible screen is subjected to too much force (which may cause damage to the flexible screen).

[0099] Please refer to Figure 11 , the second housing 18 comprises a holding shell 181 and a first support 182, the holding shell 181 and the first support 182 are connected, the controller 17 is located on the first support 182, and the holding shell 181 is connected with the second edge of the flexible screen. The first support 182 is a support inside the display device, and can be used to arrange some structures inside the display device, for example, the first support 182 can be provided with a circuit board (such as a mainboard), a vacuum chamber (VC) heat dissipation plate, a battery, a graphene sheet and the like. In addition, please refer to Figure 13 , Figure 13 is Figure 11 the structure diagram of the holding shell in the display device shown in FIG. 13, the holding shell 181 can be used for the user to hold, so that the user can stably hold the display device.

The controller can control the start of the screen shaft motor assembly in the display device to drive the screen shaft to rotate, and wind the flexible screen on the screen shaft, so as to convert the display device to the folded state.

[0101] For example, the display device can be provided with physical buttons (such as a lock screen button or a separate state conversion button), and the user can trigger the display device to convert between the folded state and the unfolded state, or the display device can display a virtual button on the flexible screen, and the user can trigger the virtual button to trigger the display device to convert between the folded state and the unfolded state, or the display device can receive a voice instruction to send an instruction to the controller to trigger the display device to convert between the folded state and the unfolded state. In addition, the display device can also accept an instruction sent by an external control device to trigger the display device to convert between the folded state and the unfolded state. The control device can be a smart wearable device (such as a smart watch, a smart bracelet, a smart ring, and smart glasses), or a separate control device for controlling the display device. The embodiments of the present application do not limit this.

[0102] In addition, the controller can also trigger the display device to convert between the folded state and the unfolded state under the control of some preset instructions. For example, the preset instructions for triggering the conversion to the unfolded state can include: triggering the unfolding instruction when the display device is turned on; triggering the unfolding instruction when the display device plays a video; triggering the unfolding instruction when the display device starts a preset application (App) (the preset application can be set by the user, or some applications can be set by default by the system, such as a drawing program, a text reading program, a photo browsing program, and an editing program for photos and videos). The preset instructions for triggering the conversion to the folded state can include: triggering the folding instruction when the display device is turned off; triggering the folding instruction when a lock screen instruction is received; and the like.

[0103] In addition, please refer to Figure 14 , Figure 14 is Figure 11 Fig. 1 shows a structure diagram of a first housing in the display device.

In addition, the first connecting piece r1 can be an L-shaped plate. Two plate surfaces of the L-shaped plate are fixedly connected (for example, screw connection) with the first strip-shaped track 211 and the motor support 161 respectively. The L-shaped plate has simple and solid structure, and can realize the function of the first connecting piece r1.
