The invention provides a flexible screen assembly.

In the embodiment of the present invention, as shown in fig. 1 to 7, the flexible screen assembly includes a flexible display screen 10, a winding and unwinding assembly 20, and a driving module 30.

Specifically, the flexible display screen 10 refers to a screen having both display capability and bending capability, and may be configured as an LED display screen, a miniLED display screen, or an OLED (Organic Light-Emitting Diode) display screen. Specifically, in this embodiment, the flexible display screen 10 is a flexible transparent LED display screen, and the flexible transparent LED display screen can be configured to display on a single side (i.e. only one side of the flexible transparent LED display screen is provided with LED beads), or display on both sides (i.e. simultaneously both sides of the flexible transparent LED display screen are provided with LED beads). When the flexible transparent LED display screen is set to be displayed on a single side, colored backgrounds such as a black background template and a white background template can be arranged on the non-display side of the flexible transparent LED display screen, so that the display effect of the flexible transparent LED display screen is improved. The LED lamp bead may be an RGB package with a built-in control chip or an RGB package without a built-in control chip, but is not limited thereto.

The winding and unwinding assembly 20 includes a winding shaft 21, and in this embodiment, the winding shaft 21 is disposed in a cylindrical shape. Of course, in other embodiments, the reel 21 may be configured to be approximately circular, such as oval, square, hexagonal, octagonal, and the like. The material of the reel 21 may be ceramic (such as alumina, zirconia, etc.), metal (such as aluminum alloy, stainless steel, etc.), plastic (such as phenolic resin, epoxy resin, etc.), or a composite material of the three. In the present embodiment, the reel 21 is connected to one end of the flexible display 10.

In the present embodiment, the roller 21 is controllably rotated to wind the flexible display 10 on the roller 21 or release the flexible display 10 wound on the roller 21. Here, since the rotation of the reel 21 is controllable, the whole flexible display 10 is not completely rolled or unrolled every time the flexible display 10 is rolled/unrolled, and only a part of the flexible display 10 may be rolled/unrolled. It should be understood that the rolling does not damage the flexible display 10, so that the flexible display 10 can normally display the picture in the half-rolled/rolled state. It should be noted that the controllable rotation of the winding shaft 21 also includes that the winding shaft 21 can wind/unwind the flexible display screen 10 according to a predetermined rule. For example, when the flexible screen assembly of the present application is used as a window covering, the roller 21 may automatically wind or release the flexible display screen 10 according to the local sunrise/sunset time.

The driving module 30 includes a data receiving module 31 and a display driving IC32, and the data receiving module 31 is electrically connected to the display driving IC 32.

Of course, the data receiving module 31 may also be configured to include any two or all of a wired receiving module, a wireless receiving module and a data jack. The data receiving module 31 is capable of receiving picture data and video data and transmitting them to the display driver IC 32. It should be understood that other types of data, such as control signal data, audio data, etc., can be received in addition to picture data and video data. The driving module 30 is connected to the other end of the flexible display panel 10, and the flexible display panel 10 is electrically connected to the driving IC. The display driver IC32 can send a control signal to the flexible display screen 10 according to the picture data or the video data received by the data receiving module 31 to control the flexible display screen 10 to play corresponding pictures or videos.

Further, in the present embodiment, the driving module 30 and the winding and unwinding assembly 20 are disposed on the same side of the flexible display screen 10. Specifically, in some embodiments, the driving module 30 may be configured to rotate and stop in synchronization with the spool 21, wherein the driving module 30 can rotate when the spool 21 rotates and the driving module 30 stops when the spool 21 stops rotating. Set up like this, can avoid flexible display screen 10 to take place to interfere with drive module 30 when rolling, and then in order to realize flexible display screen 10's free rolling and expansion. While in other embodiments, drive module 30 may be configured to rotate relative to spool 21, in which case drive module 30 does not rotate with the rotation of spool 21. At this time, the driving module 30 and the flexible display screen 10 may be connected through a slip ring (e.g., an electrical slip ring, a fluid slip ring, an optical slip ring, etc.).

For example, if the flexible display screen 10 is unfolded and then extends in the up-down direction, the winding and unwinding assembly 20 is disposed at the upper end of the flexible display screen 10. Then, when the winding shaft 21 rotates clockwise (of course, it may also be set to rotate counterclockwise), the flexible display screen 10 can be wound on the winding shaft 21, and when the winding shaft 21 rotates counterclockwise, the flexible display screen 10 wound on the winding shaft 21 can be released and then be unfolded into a complete screen. The unfolded display screen can play pictures and/or videos in cooperation with the driving module 30.

It is also worth noting that in some embodiments, when the roller 21 releases the flexible display 10, the flexible display 10 may be automatically unfolded by gravity or by a driving force. The traction force may be provided by a driving mechanism having a driving end, which may be connected to the driving module 30 or directly connected to the other end of the flexible display screen 10. The driving mechanism can be arranged to be an active mechanism, such as a motor, a cylinder, a hydraulic cylinder and the like, and can also be arranged to comprise a passive mechanism, such as a spring, a coil spring and the like.

It can be understood that this application technical scheme flexible screen subassembly is through connecting the one end with flexible display screen 10 in spool 21 to drive module 30 is connected at flexible display screen 10 with one end, so, through the rotation of spool 21, can the rolling or expand flexible display screen 10, thereby can be when acquireing bigger display surface, reduce the occupation space of screen when storage, carrying, in order to compromise display device's display area and occupation space simultaneously. Meanwhile, the rolling mode does not cause the screen to have creases, thereby being beneficial to ensuring the long-term display effect of the flexible display screen 10. It is thus clear that compare in traditional foldable display screen, the flexible screen subassembly of this application has that display area is big, occupation space is little when accomodating, display effect is good, stability is high and long service life's advantage.

In some embodiments, the drive module 30 is provided to the spool 21. Thus, the driving module 30 can be driven by the scroll 21 to synchronously rotate and synchronously stop with the scroll 21, so that the synchronism of the movement between the driving module 30 and the scroll 21 can be improved, and the structural complexity of the flexible screen assembly can be reduced. Specifically, in the radial direction of the reel 21, the driving module 30 may be disposed outside the reel 21, inside the reel 21, or in the body of the reel 21; the driving module 30 may be disposed at either end of the winding shaft 21 or between both ends of the winding shaft 21 in the axial direction of the winding shaft 21. Of course, the design of the present application is not limited thereto, and in some embodiments, the driving module 30 may be provided separately from the reel 21, and at this time, the driving module 30 may be driven by a driving mechanism separately from the reel 21 to achieve synchronous rotation and stop of the driving module 30 and the reel 21.

In some embodiments, an accommodating space 21a is formed in the winding shaft 21, a first opening 211a communicating with the accommodating space 21a is formed in the winding shaft 21, and the driving module 30 is disposed in the accommodating space 21a and electrically connected to the flexible display screen 10 through the first opening 211 a. That is, the driving module 30 is disposed in the reel 21, so that the flexible display screen 10 and the driving module 30 can be prevented from interfering with each other, and the reel 21 can be freely wound on the reel 21. In addition, the driving module 30 is arranged in the reel 21, so that the space is saved, and the complexity of the structure of the reel 21 can be reduced. Of course, the design of the present application is not limited thereto, and in other embodiments, the driving module 30 may be disposed at other positions of the reel 21.

In some embodiments, the driving module 30 further includes a driving board 33 and a connecting board 34, the display driver IC32 and the data receiving module 31 are both disposed on the driving board 33, the connecting board 34 is electrically connected to the driving board 33, a plurality of first interfaces (not labeled) are disposed on the connecting board 34, the plurality of first interfaces are connected to the plurality of flat cables of the flexible display screen 10 one by one, and a second interface (not labeled) is disposed on the connecting board 34, and the second interface is connected to the driving board 33.

Specifically, one end of the flexible display screen 10 connected to the driver IC is provided with a plurality of FPC (flexible Printed circuit) cables, and the plurality of FPC cables 11 are provided with conductive traces capable of transmitting current signals and voltage signals, so as to not only supply power to the pixel units on the flexible display screen 10, but also enable the pixel units to be lit with a set brightness and color. The flexible display panel 10 is electrically connected to the display driver IC32 through the FPC cable 11. It should be noted that, in some embodiments, the flexible display panel 10 may also be electrically connected to the display driver IC32 through an FPC cable 11. It should be understood that the design of the present application is not limited thereto, and in other embodiments, the flexible display screen 10 may be electrically connected to the display driver IC32 through a PCB, a wire harness, or the like.

Optionally, the conductive traces on the FPC cable 11 may be metal, or may be transparent conductive traces (mainly metal grid lines made of ITO, nano silver, or copper alloy).

It should be noted that, since the number of the FPC lines 11 on the flexible display 10 is determined according to the width (or pixels in the width direction) of the flexible display 10, that is, the number of the FPC lines 11 is difficult to be reduced. Accordingly, if the driving board 33 is electrically connected to the flexible display screen 10, a corresponding number of interfaces need to be provided, which may make it difficult to reduce the size of the driving board 33, and further make the occupied space of the driving module 30 larger.

Based on above-mentioned reason, the technical scheme of this application sets up drive plate 33 to be connected through connecting plate 34 and flexible display screen 10 electricity, like this, can set up the length of connecting plate 34 into the width looks adaptation with flexible display screen 10, and is less relatively with the size setting of drive plate 33 simultaneously, so, can be on the basis of guaranteeing that drive module 30 and flexible display screen 10 are normally connected, reduce the occupation space of flexible display screen 10. That is, the above design has an advantage of reducing the space occupied by the driving module 30.

In some embodiments, the driving board 33 is provided as a flexible circuit board, and may also be provided as a rigid printed circuit board.

Specifically, the connection plate 34 may be fixed to the first cylinder 211 and/or the second cylinder 212, and the driving plate 33 may be fixed to the second cylinder 212.

It is noted that at least one end of the second cylinder 212 is provided with a communication port communicating with the second cavity 21c, and the communication port allows external lines and the like to enter the second cavity 21c to be connected to the driving plate 33.

With the above structure, the drive plate 33 can be separated from the connection plate 34 in the radial direction of the spool 21, so that not only a sufficient space is provided for the long connection plate 34, but also a sufficient space is provided for the drive plate 33. In addition, the second cylinder 212 separates the driving plate 33 and the connecting plate 34, so that the structure of the reel 21 can be simplified, and the material cost and the assembly cost of the reel 21 can be reduced.

Of course, the present disclosure is not limited thereto, and in other embodiments, the driving plate 33 and the connecting plate 34 may be separated by providing other structures, such as by providing a partition in the reel 21 to separate the driving plate 33 and the connecting plate 34; in some embodiments, the drive plate 33 and the connecting plate 34 may also be disposed within the same cavity.

In some embodiments, drive module 30 further includes an adapter 35, and connection plate 34 is connected to drive plate 33 through adapter 35. That is, the connection plate 34 and the driving plate 33 are connected by the adapter 35.

Since the length of the driving plate 33 can be set relatively short by the arrangement of the connecting plate 34, the driving plate 33 and the motor can be simultaneously disposed in the second cavity 21 c. Thus, the integration degree of the flexible screen assembly can be greatly improved, and the reduction of the volume of the flexible screen assembly is facilitated.

It will be appreciated that the first cylinder 211 is driven to rotate by a motor, which can be controlled to effect a controlled rotation of the spool 21. For example, if the motor serves as a motor, the timing control, the quantitative control, and the like of the reel 21 can be realized by writing a specific program in the servo controller. In addition, the servo controller can be connected with a wireless transceiver to realize remote control.

Alternatively, the torque of the motor is between 0.1N · m and 1000N · m.

Optionally, the motor has a length of between 1cm and 2000 cm. Preferably, the length of the motor is between 5cm and 100 cm. For example, the length of the motor may be 1cm, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, 20cm, 30cm, 40cm, 50cm, 60cm, 70cm, 80cm, 90cm, 100cm, 200cm, 300cm, 400cm, 500cm, 600cm, 700cm, 800cm, 900cm, 1000cm, 1500cm, 2000cm, and the like.
