1 to 7, an embodiment of the present disclosure provides a display device, which includes a flexible display screen 1, a control unit, and a driving unit. The display screen 1 is used to display images, the drive unit is used to drive the display screen 1 to deform, and the control unit is used to control the drive unit so that the drive unit drives the display screen 1 into a curved shape that can be wrapped around the wrist, or the drive unit drives the The display screen 1 is formed in a flat plate shape.

The main body of the display device of the present disclosure is a flexible display screen 1, and the display screen 1 refers to a display panel that can display content on the display side. The display screen 1 is flexible, that is, it can be deformed without being damaged under the action of an external force.

The flexible display screen 1 is driven by the drive unit in the display device, and can be deformed into a rectangular parallelepiped flat shape similar to that of a normal smart phone (refer to Figures 2 to 4); or can be deformed into a smart wrist which can be wrapped around the wrist. The watch has a similar curved shape (refer to FIGS. 5 to 7), that is, the entire display screen 1 can be directly bent around the wrist, thereby becoming a smart watch.

It should be understood that usually the display screen 1 can be "switched" between the above two states, but it can also be in other shapes if it is artificially deformed or the like.

The specific form of the driving unit is various, as long as it can realize the function of driving the display screen 1 into a curved shape or a flat shape that can be wrapped around the wrist.

For example, referring to FIGS. 5 to 7, the driving unit may include a plurality of fixed plates 8, which are located on the opposite side of the display side of the display screen 1, and are sequentially arranged along the horizontal direction of the display screen 1. The edges of the adjacent fixing plates 8 are connected by rotating shafts or the like, so that the shape of the display screen 1 can be controlled by controlling the relative angle between the fixing plates 8.

The specific methods of the angle control between the fixing plates 8 are various.

For example, the driving unit may include a motor, which is used to control the rotation of the rotating shaft between the edges of the adjacent fixed plates 8 so as to form a desired angle between the adjacent fixed plates 8.

For another example, an electromagnet can be provided on each fixing plate 8, and the switch, polarity, and magnetic size of the electromagnet can be controlled to make the adjacent fixing plates receive attraction and repulsion in a specific direction, so that The fixed plate 8 is at a specific angle.

The driving unit is controlled by the control unit of the display device. Specifically, the control unit may control the driving unit according to the control instructions it receives, or it may analyze the data it receives to obtain an analysis result, and control the driving unit according to the analysis result.

Both the driving unit and the control unit may be located on the opposite side of the display side of the display screen 1 or embedded in the display screen 1. When the user needs to carry the display device, he can send a control instruction to the control unit to make the control unit control the drive unit, so that the drive unit drives the display screen 1 to change into a bend similar to a smart watch that can be wrapped around the wrist; For conventional screens (such as playing games, watching videos, etc.), control instructions can be sent to the control unit to make the control unit control the drive unit, and then the drive unit drives the display screen 1 to change into a flat shape similar to the shape of an ordinary smart phone.

In some related technologies, the flexible display screen is made in a fixed curved shape, and the shape will not change dynamically during use. The manufacturing process of the flexible display screen has been very mature, and large-scale mass production has been achieved. However, the above products are actually not deformable, so the advantages of the flexible display screen have not been fully utilized; at the same time, the display screen is actually immutable Therefore, in order to make it removable from the wrist, for example, a smart watch made with a flexible display screen with a fixed curved surface must be equipped with a strap before it can be worn like an ordinary watch.

The drive unit of the display device of the embodiment of the present disclosure can be controlled by the control unit to drive the display screen 1 to change into a curved shape similar to a smart watch that can be wrapped around the wrist, so it can be like an ordinary watch without a strap. Wearable; at the same time, because the drive unit can also be controlled by the control unit to drive the display screen 1 to change to a flat shape similar to that of ordinary smart phones, so it can also meet the needs of users for large screens when surfing the Internet, gaming, and audio-visual audiovisual. Improve the user experience.

2 to 4, the display device may further include a human body proximity sensor located on the opposite side of the display side of the display screen 1 for detecting whether the display device is close to the human body.

The control unit is used for controlling the driving unit when the human body proximity sensor detects that the display device is close to the human body, so that the driving unit drives the display screen 1 to form a curved shape that can be wound on the wrist.

The display device of the present disclosure may also include a human body proximity sensor located on the back of the display screen 1 (ie, the opposite side of the display side). The human body proximity sensor is used to detect whether there is a human body or a specific part of the human body (such as a wrist) is approaching. Or when a specific part of the human body is approaching (or when the display device is approaching the human body), it sends a signal to the control unit so that the control unit sends a control instruction to the drive unit, so that the drive unit drives the display screen 1 to change into a smart wrist that can be wrapped around the wrist. The watch is similarly curved; when there is no human body approaching, the human body proximity sensor does not send this signal to the control unit.

The human proximity sensor is located on the back of the display screen 1 because when the display device is worn, the display screen 1 is on the side that is not close to the human body. If the human proximity sensor is on the display side, it is not easy to detect whether the display device is approaching the user (or That is, whether the human body or a specific part of the human body is approaching the display device).

Since the human body proximity sensor sends a signal to the control unit when it detects the human body is approaching, the display screen 1 can be changed to a smart watch that can be wound on the wrist without inputting a control command when the human body or a specific part of the human body (such as the wrist) is approaching. The similar curved shape is convenient for users to use.

2 to 4, the human body proximity sensor may be the pulse sensor 5.

The human body proximity sensor of the display device of the present disclosure may be the pulse sensor 5, that is, when the pulse sensor 5 senses the pulse, it means that the display device has been close to the user's wrist, and the pulse sensor 5 sends a signal to the control unit so that the control unit sends control to the drive unit The instruction further causes the driving unit to drive the display screen 1 to change into a curved shape similar to a smart watch that can be wrapped around the wrist to be buckled on the user's wrist.

The display device of the present disclosure can be worn on the wrist. In most cases, when the user needs to wear the display device, the display device is brought close to the wrist, and the wrist part can clearly feel the human pulse. Therefore, the human body proximity sensor may be the pulse sensor 5 to more easily detect that the display device has approached the user's wrist.

2 to 4, the pulse sensor 5 may be an infrared sensor or a micro pressure sensor.

The specific types of the pulse sensor 5 can be various, as long as the pulse can be detected.

The pulse sensor 5 may be an infrared sensor, that is, using the principle of infrared rays, the blood vessel is irradiated with infrared rays of a specific wavelength to detect the blood change signal in the blood vessel. After the circuit is processed, the pulse signal is separated. If the pulse signal is detected, it means that the pulse is detected and the display device is close to the user's wrist. It sends a signal to the control unit so that the control unit sends a control command to the drive unit, so that the drive unit drives the display screen 1 The change is that a curved shape similar to a smart watch that can be wrapped around the wrist is buckled on the user's wrist.

The pulse sensor 5 can also be a micro pressure sensor, that is, using the principle of micro pressure, the sensor is close to the skin of the measuring point, and the pressure fluctuation of the pulse beating is converted into a pulse signal output. If the pulse signal is detected, the pulse is detected. The display device has approached the user's wrist, and sends a signal to the control unit so that the control unit sends a control instruction to the drive unit, so that the drive unit drives the display screen 1 to change into a curved shape similar to a smart watch that can be wrapped around the wrist and clasped on the user's wrist superior.

Infrared sensors and micro pressure sensors are commonly used sensors, so the technology is mature and the detection effect is good and easy to implement.

2 to 4, the display device may further include a pressure sensor 7 located on the display screen 1 for obtaining pressure data of the pressure it receives. The control unit is used for controlling the driving unit according to the pressure data, so that the driving unit drives the display screen 1 into a flat plate shape.

The display device of the present disclosure may further include a pressure sensor 7 located on the display screen 1. The pressure sensor 7 sends the pressure data it acquires to the control unit. After acquiring the pressure data, the control unit controls the driving unit according to the pressure data, and when the pressure data meets a certain condition, the driving unit drives the display screen 1 to form a flat plate shape similar to an ordinary smart phone.

The pressure sensor 7 can be implemented in various ways. For example, the pressure sensor 7 can be composed of a resistance strain gauge. Its working principle is based on the strain effect, that is, when a conductor or semiconductor material is mechanically deformed under the action of an external force, the resistance value correspondingly occurs. Variety. When a certain voltage is applied to the two ends of the resistance strain gauge and the change of the current passing through the resistance strain gauge is detected, the pressure can be calculated.

When the pressure data of the pressure sensor 7 satisfies a certain condition (for example, exceeds a certain threshold), the control unit may control the driving unit so that the driving unit drives the display screen 1 to form a flat plate shape similar to an ordinary smart phone. Therefore, the user only needs to make the pressure sensor 7 feel a specific pressure to restore the display screen 1 to a flat shape similar to an ordinary smart phone, without inputting control instructions, and the operation is simpler.

2 to 4, the pressure sensor 7 may be located on the side of the display screen 1.

The pressure sensor 7 of the present disclosure may be specifically located on the side of the display screen 1. When the user wants to restore the display screen 1 to a flat shape similar to an ordinary smart phone, only need to apply pressure on the side of the display screen 1.

If the pressure sensor 7 is located on the opposite side of the display side of the display screen 1 (that is, the back of the display screen 1), when the display screen 1 is a curved shape similar to a smart watch that can be wrapped around the wrist (or the display device When being worn on the wrist), the back of the display screen 1 is in contact with the wrist, so it is difficult to apply pressure.

If the pressure sensor 7 is located on the display side of the display screen 1 (ie, the front side of the display screen 1), the pressure sensor 7 may be detected by the pressure sensor 7 when a finger slides on the screen when the user operates, causing the display screen 1 to be erroneously deformed.

It is difficult for the user to touch the side of the display screen 1 during operation. When the display screen 1 has a curved shape similar to a smart watch that can be wrapped around the wrist (or the display device is worn on the wrist), the display screen 1 The side of the corresponding to the position of the adjustment knob of the smart watch, it is easy to touch and operate, therefore, the pressure sensor 7 located on the side of the display screen 1 is most in line with user habits.

2 to 4, the control unit is used to control the driving unit when the pressure data lasts for a preset time, so that the driving unit drives the display screen 1 to form a flat plate shape.

After the pressure sensor 7 senses the pressure, it sends the pressure data to the control unit, and the control unit determines whether to control the driving unit according to the received pressure data, so that the driving unit drives the display screen 1 to form a flat plate. If the pressure sensor 7 senses a pressure exceeding a predetermined threshold, the control unit controls the driving unit to make the driving unit drive the display screen 1 into a flat plate shape. If the user accidentally touches the pressure sensor 7, the display screen 1 may be wrongly formed into a flat shape. Therefore, the control unit controls the driving unit to make the display screen 1 into a flat shape after the pressure data exceeds a predetermined threshold for a certain period of time. This can be avoided.

The control unit can also be used to receive length data, and control the size of the curved shape formed by the display screen 1 that can be wound on the wrist according to the length data.

The control unit of the present invention can also receive length data, and the control unit can control the drive unit according to the length data, so that the drive unit can control the display screen 1 to form a wrapable display screen in some way (for example, by controlling the relative angle between the fixing plates 8) A curved shape on the wrist similar to a smart watch, and the size (for example, diameter) of the shape is the length data.

The user can input his own wrist size data into the control unit, so that the curved size of the display screen 1 is his own wrist data, which is more convenient for the user to wear.

In other words, the display device according to the present disclosure can be combined with other structures to form a terminal with more functions, such as a smart watch, a smart phone, and other communication terminals with communication functions.

The terminal may also include at least one of a front camera 2, a rear camera 6, an earpiece 3, and a light-sensitive proximity sensor 4.

In the terminal, other auxiliary devices can also be provided to enable the terminal to have corresponding extended functions (for example, camera, call, etc.).

The location of the above devices can be determined according to needs. For example, the front camera 2, the earpiece 3, and the optical proximity sensor 4 can be arranged on the display side of the display screen 1 of the display device according to the user's usage habits, and the rear camera 6 can be arranged on the display side of the display screen 1 of the display device according to the user's usage habits.
