[0025] Specifically, if Figure 1 1 is a system block diagram of a display device provided by an embodiment of the present invention; the display device includes a display module, a motion module and a support module.

[0026] Optionally, the display module includes at least one first display panel 101. Optionally, the first display panel 101 includes a passive light-emitting display panel, a self-luminous display panel, a quantum dot display panel, etc. Optionally, the passive light-emitting display panel includes a liquid crystal display panel, etc., and the self-luminous display panel includes an organic light-emitting diode display panel, a sub-millimeter light-emitting diode display panel, a micro light-emitting diode display panel, etc.

[0027] The motion module is installed on the supporting module.

[0028] When the display device is in the unfolded state, the support module has a first surface 100a. The first display panel 101 is located on the first surface 100a. The motion module is used to drive the first display panel 101 to move on the first surface 100a, so as to enable the first display panel 101 to present a complete image by means of the persistence of vision effect. This allows the display device to have a display area larger than the size of the display panel, thereby reducing the limitation of the display panel size on the display area of ​​the display device and enabling the display device to meet the design requirements of large-size displays.

[0029] Optionally, the display device further includes a display control module configured to parse received display material according to a corresponding algorithm to obtain a control signal, and transmit the control signal to a drive system of the display device. The drive system then controls the display module and the motion module simultaneously, so that when the first display panel 101 moves within the first surface 100a, it displays corresponding information based on different motion positions. The control signal includes image information corresponding to different motion positions.

[0030] Optionally, the display control module includes an image processing unit configured to receive display material and process and convert the display material to generate the control signal. Optionally, the image processing unit may include an image receiving component, an image processing component, and a conversion component, wherein the image receiving component is configured to receive the display material, and the image processing component and the conversion component are configured to convert the received display material into the control signal. Optionally, the image processing unit may include a graphics processor, etc.

[0031] Optionally, the display module further includes a display driver control unit. The display driver control unit is configured to generate a plurality of display control signals based on the output signal of the drive system, so that the first display panel 101 displays corresponding image information at different movement positions according to the display control signals when the first display panel 101 moves with the motion module within the first surface 100a. Optionally, when displaying the same frame, each time the first display panel 101 moves, the display content is updated accordingly, so that the information corresponding to the frame is displayed at the corresponding position.

[0032] Optionally, the display driving control unit includes a pixel driving circuit, a gate driving circuit, etc.

[0033] Optionally, the display device further includes a mechanical drive control unit. The mechanical drive control unit includes the motion module and the support module. Optionally, the mechanical drive control unit further includes a mechanical drive controller. The mechanical drive controller receives the output signal of the drive system to generate a switch control signal, and transmits the generated switch control signal to the motion module, thereby controlling the operating state of the motion module via the mechanical drive controller.

[0034] Optionally, the motion module includes a driver 401 and a motion mechanism. The mechanical drive controller receives the output signal of the drive system to generate the switch control signal, and transmits the switch control signal to the driver 401 to control the opening or closing of the driver 401 through the mechanical drive controller. The motion mechanism is driven by the driver 401 to move the first display panel 101 within the first surface 100a.

[0035] Optionally, the motion mechanism further includes a counterweight unit, etc. Optionally, the display device further includes an auxiliary module, which includes but is not limited to a power module, an audio device, a Wifi receiver, etc.

[0036] like Figures 2A to 2C It is a structural schematic diagram of a display device provided by an embodiment of the present invention in a folded state and an unfolded state.

[0037] Optionally, when the display device is in the unfolded state, the first display panel 101 may move back and forth within the boundary of the first surface 100 a driven by the motion module, and may also rotate under the drive of the motion module.

[0038] Since the display device realizes a larger display screen through the movement of the first display panel 101 within the first surface 100a and the visual persistence effect, in order to avoid the problem of discontinuous display of the display screen caused by the movement speed of the first display panel 101 being too slow, the movement parameters of the first display panel 101 on the first surface 100a are limited.

[0039] Optionally, the motion parameter of the first display panel 101 within the first surface 100 a is related to the number of frames required to achieve continuous display of images.

[0040] Optionally, the motion module is configured to drive the first display panel 101 to move back and forth within the boundaries of the first surface 100a, with the linear velocity of the first display panel 101 within the first surface 100a being greater than or equal to mL / s. m represents the minimum number of display frames required for continuous image display, and L represents half the distance the first display panel 101 can move back and forth within the first surface 100a; that is, L represents the distance within the first surface 100a available for the first display panel 101 to move back and forth. By ensuring that the linear velocity of the first display panel 101 within the first surface 100a is greater than or equal to mL / s, the problem of discontinuous display on the display device caused by the first display panel 101 moving too slowly within the first surface 100a can be avoided.

[0041] Optionally, m is greater than or equal to 24. Optionally, m is equal to 24, 25, 26, ..., 30, ..., 35, ..., 40, ..., 45, ..., 50, ..., 55, 56, 57, 58, 59 or 60.

[0042] Optionally, the motion module is configured to drive the first display panel 101 to rotate within the boundaries of the first surface 100a; wherein the first display panel 101 rotates at least n times per second, where n represents the minimum number of display frames required for continuous display. By ensuring that the number of rotations per second of the first display panel 101 is greater than or equal to the minimum number of display frames required for continuous display, the display device can avoid displaying discontinuous images due to the first display panel 101 moving too slowly within the first surface 100a.

[0043] Optionally, n is greater than or equal to 24. Optionally, n is equal to 24, 25, 26, ..., 30, ..., 35, ..., 40, ..., 45, ..., 50, ..., 55, 56, 57, 58, 59 or 60. Accordingly, the first display panel 101 rotates within the first surface 100a at least 24, 25, 26, ..., 30, ..., 35, ..., 40, ..., 45, ..., 50, ..., 55, 56, 57, 58, 59 or 60 times per second.

[0044] Since the display device realizes a larger display screen through the movement of the first display panel 101 within the first surface 100a and the visual persistence effect, in order to avoid the problem of blurred display screen caused by the first display panel 101 moving too fast, the display device can further limit the movement parameters of the first display panel 101 on the first surface 100a on the basis that the display device can avoid the problem of discontinuous display screen caused by the first display panel 101 moving too slowly.

[0045] Optionally, see Figures 2A to 2C The motion module is used to drive the first display panel 101 to move back and forth within the first surface 100a. The linear velocity of the first display panel 101 within the first surface 100a is greater than or equal to 24 L / s and less than or equal to 120 L / s, so as to avoid the problem of discontinuous display caused by the first display panel 101 moving too slowly within the first surface 100a, and to avoid the problem of blurred image caused by the first display panel 101 moving too fast within the first surface 100a.

[0046] Optionally, the linear velocity of the first display panel 101 moving within the first surface 100a is equal to 24 L / s, 25 L / s, 26 L / s, ..., 30 L / s, ..., 35 L / s, ..., 40 L / s, ..., 45 L / s, ..., 50 L / s, ..., 55 L / s, 56 L / s, 57 L / s, 58 L / s, 59 L / s or 60 L / s, 61 L / s, 62 L / s. L / sec, 63L / sec, 64L / sec, …, 70L / sec, …, 75L / sec, …, 80L / sec, …, 85L / sec, …, 90L / sec, …, 95L / sec, …, 100L / sec, …, 105L / sec, …, 110L / sec, …, 115L / sec, 116L / sec, 117L / sec, 118L / sec, 119L / sec or 120L / sec.

[0047] Optionally, the motion module is used to drive the first display panel 101 to rotate within the first surface 100a, and the first display panel 101 rotates at most 360 times per second to avoid the problem of discontinuous display caused by the first display panel 101 moving too slowly within the first surface 100a and the problem of blurred image caused by the first display panel 101 moving too fast within the first surface 100a.

[0048] Optionally, the first display panel 101 rotates 24 circles, 25 circles, 26 circles, ..., 30 circles, ..., 35 circles, ..., 40 circles, ..., 45 circles, ..., 50 circles, ..., 55 circles, 56 circles, 57 circles, 58 circles, 59 circles, 60 circles, ..., 65 circles, ..., 70 circles, ..., 75 circles, ..., 80 circles, ..., 85 circles, ..., 90 circles, ..., 95 circles, ..., 100 circles, ..., 105 circles, ..., 110 circles, ..., 115 circles, 116 circles, 117 circles, 118 circles, 119 circles, 120 circles, ..., 150 circles, ..., 240 circles, ... or 360 circles per second within the first surface 100a.

[0049] When the display device is displaying, if the moment of switching the displayed image coincides with the moment when the first display panel 101 is at a certain point between the starting point and the end point of the movement, then after the image switch, since the information required to be displayed by the first display panel 101 will also change, the image before the image switch and the image after the image switch generated by the movement of the first display panel 101 in combination with the visual aftereffect may overlap or tear. To this end, the first display panel 101 can be made to perform at least one reciprocating motion or rotational motion within the first surface 100a within one frame time, so that the image switching moment coincides with the moment when the first display panel 101 is at the starting point of the movement, or the image switching moment coincides with the moment when the first display panel 101 is at the end point of the movement. It is understood that the problem of image overlap or tearing can also be improved through algorithms.

[0050] It is understood that the display device may further include a plurality of first display panels 101. The plurality of first display panels 101 move separately within the first surface 100a, so that the display device displays the image through the movement of the plurality of first display panels 101 and the persistence of vision effect, thereby reducing the limitation of the display panel size on the display area of ​​the display device.

[0051] Optionally, the display device may further include at least one second display panel 102, and the second display panel 102 is fixedly mounted on the supporting module, such as Figure 2B to Figure 2C The second display panel 102 includes a passive light emitting display panel, a self-luminous display panel, a quantum dot display panel, etc.

[0052] Optionally, when the first display panel 101 moves to the end point of the movement, and / or when the first display panel 101 moves to the starting point of the movement, the first display panel 101 is connected to the second display panel 102, so as to utilize the second display panel 102, the first display panel 101 and the visual persistence effect to enable the display device to achieve the design requirements of large-size display.

[0053] Optionally, the aspect ratio of the first display panel 101 may be the same as or different from the aspect ratio of the second display panel 102. Optionally, the aspect ratio of the first display panel 101 is greater than or equal to 4:1. Optionally, the aspect ratio of the first display panel 101 is 16:9, 4:3, or 4:1, etc.

[0055] Optionally, the support module and the movement module may have different structural forms when the display device is in the folded state and the unfolded state, so that the display device can meet the design requirements of large-size display and portability.

[0056] Taking the display device including the first display panel as an example, the structures of the support module and the movement module are described.

The first supporting mechanism 201 and the second supporting mechanism 202 have the first surface 100a. Figure 3A shown.

[0059] When the display device is in the folded state, the first supporting mechanism 201 and the second supporting mechanism 202 are stacked.

It is understood that the first display panel 101 and the second display panel 102 being adjacent to each other may mean that there is no gap between the first display panel 101 and the second display panel 102.

The third gear 4022 is disposed within the spacing grooves 202d. The synchronous belt 403 is sleeved on the third gear 4022. The rotating shaft 4021 is mounted on the third support portion 2021 and fixedly connects the second gear 4013 and the third gear 4022. The first support portion 2011, the second support portion 2012, the third support portion 2021, and the fourth support portion 2022 enclose a storage area for the synchronous belt 403. Optionally, the surface of the synchronous belt 403 is lower than the surfaces of the second supporting portion 2012 and the fourth supporting portion 2022 to protect the synchronous belt 403 .

[0074] Combine Figures 3A to 3C Taking the display device including the first display panel 101 as an example, the mutual cooperation relationship between the first display panel 101, the supporting module and the motion module in the unfolded state and the folded state is described.

[0075] When the display device is deployed, the hinge connecting the first support mechanism 201 and the second support mechanism 202 is first opened, and the first support mechanism 201 and the second support mechanism 202 have the first surface 100a. Then, the locking knob 302 is rotated, causing the locking member 301 to rotate under the driving force of the locking knob 302, so that the end of the locking member 301 extends into the second support mechanism 202, and the first support mechanism 201 and the second support mechanism 202 are locked in a state having the first surface 100a. Thereafter, the driving source 4011 outputs power, causing the first gear 4012 to drive the second gear 4013 to rotate. The third gear 4022, driven by the second gear 4013 and the rotating shaft 4021, drives the synchronous belt 403 to rotate. The first display panel 101 located on the synchronous belt 403 is driven by the synchronous belt 403 to move within the first surface 100a.

[0076] When the display device is in the folded state, the support modules are folded so that the first support mechanism 201 and the second support mechanism 202 are stacked, and the synchronous belt 403 is in a relaxed state. Figure 5It is a schematic structural diagram of a synchronous belt in a folded state provided by an embodiment of the present invention.

[0077] It can be understood that when the first display panel 101 rotates within the first surface 100 a , the first display panel 101 can be directly driven by the driving member 401 without the need for a synchronous belt 403 .

[0078] When the display device includes a plurality of the first supporting mechanisms 201, the display device may be provided with a plurality of locking modules. Optionally, the number of the locking modules is less than or equal to the number of the first supporting mechanisms.

[0079] In the present application, when the display device is in a folded state, the motion module is not started, and the display device can directly display through the first display panel 101 or the first display panel 101 and the second display panel 102. Since the size of the display device is small when it is in the folded state, it is easy to carry and transfer. When the display device is in an unfolded state, the display control module parses the received display material according to the algorithm and outputs a control signal to the drive system. The drive system controls the display module and the motion module in conjunction with the control signal to make the first display panel 101 move within the first surface 100a. At the same time, the first display panel 101 is controlled by the display drive unit so that the first display panel 101 displays image information that matches the motion position, thereby utilizing the human eye's visual persistence effect to present a complete image with a transparent display effect. Therefore, the present application can reduce the limitation of the size of the display panel on the display area of ​​the display device by utilizing the movement of the first display panel 101 within the first surface 100a and the visual persistence effect. By enabling the display device to switch between unfolded and folded states, the display device can take into account the design requirements of large-size display and portability.

[0080] It can be understood that the display device includes a movable display device (such as a laptop computer, a mobile phone, etc.), a fixed terminal (such as a desktop computer, a television, etc.), a measuring device (such as a sports bracelet, a thermometer, etc.), etc.

The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
