The invention provides a flexible screen assembly.
In the embodiment of the present invention, as shown in fig. 1 to 6, the flexible screen assembly includes a winding and unwinding assembly 10, a driving module 20, and a flexible display screen 30.
The flexible display screen 30 is a screen having both display capability and bending capability, and may be 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 30 is a flexible transparent LED display screen, and the flexible transparent LED display screen can be set to be displayed on a single side (i.e. only one side of the flexible transparent LED display screen is provided with LED beads), or displayed on two sides simultaneously (i.e. the two sides of the flexible transparent LED display screen are provided with LED beads simultaneously). 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 10 includes a winding shaft 11, and in this embodiment, the winding shaft 11 is disposed in a cylindrical shape. Of course, in other embodiments, the reel 11 may be configured to be approximately circular, such as oval, square, hexagonal, octagonal, and the like. The material of the reel 11 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 this embodiment, the reel 11 is connected to one end of the flexible display 30.
The driving module 20 includes a data receiving module 21 and a display driving IC22, and the data receiving module 21 is electrically connected to the display driving IC 22. Data receiving module 21 may include a wired receiving module, such as RJ-45 interface, RJ-11 interface, SC fiber interface, FDDI interface, AUI interface, BNC interface, Console interface, etc.; the wireless receiving module can be arranged to comprise a WI-FI module, a Bluetooth module, a 2.4G communication module, an infrared receiving module, a 2G/3G/4G/5G communication module and the like; or may be configured to include data ports such as USB-a ports, USB-C ports, TF slot ports, SD slot ports, and lightning ports. Of course, the data receiving module 21 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 21 is capable of receiving picture data and video data and transmitting them to the display driver IC 22. 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 20 is connected to the other end of the flexible display 30, and the flexible display 30 is electrically connected to the display driving IC 22. The display driver IC22 can send a control signal to the flexible display 30 according to the picture data or video data received by the data receiving module 21 to control the flexible display 30 to play corresponding pictures or videos.
In the solution of the present application, the reel 11 is controllably rotated to wind the flexible display 30 on the reel 11, or release the flexible display 30 wound on the reel 11. Specifically, if the reel 11 and the driving module 20 are disposed in the up-down direction and the reel 11 is disposed above the driving module 20, then when the reel 11 rotates clockwise (of course, it may also be set to rotate counterclockwise), the flexible display 30 can be wound on the reel 11, and when the reel 11 rotates counterclockwise, the flexible display 30 wound on the reel 11 can be released and then unfolded into a complete screen. The developed display screen can play pictures and/or videos in cooperation with the data receiving module 21 and the display driver IC 22. Here, since the rotation of the reel 11 is controllable, the flexible display 30 is stored/released each time, the whole flexible display 30 is not completely stored/released each time, and only a part of the flexible display 30 may be stored/released. It should be understood that the rolling does not damage the flexible display 30, and therefore, the flexible display 30 can normally display the picture in the half-rolled/rolled state.
It should be noted that the controllable rotation of the reel 11 also includes the reel 11 being able to reel/reel the flexible display 30 according to a predetermined rule. For example, when the flexible screen assembly of the present application is used as a window covering, the roller 11 may automatically wind or release the flexible display screen 30 according to the local sunrise/sunset time.
It is also worth noting that in some embodiments, when the flexible display 30 is released by the reel 11, the flexible display 30 may be automatically unfolded by gravity or may be unfolded 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 20 or directly connected to the other end of the flexible display 30. The driving mechanism can be configured to be an active mechanism, such as a motor, a cylinder, a hydraulic cylinder, etc., or a passive mechanism, such as a spring, a coil spring, etc.
It can be understood that this application technical scheme flexible screen subassembly, through connecting the one end with flexible display screen 30 in spool 11, the other end is connected with drive module 20, so, through the rotation of spool 11, can the rolling or expand flexible display screen 30 to can be when obtaining bigger display surface, reduce the occupation space of screen when storage, carrying, compromise display device's display area and occupation space simultaneously. Meanwhile, the rolling mode does not cause the screen to generate creases, thereby being beneficial to ensuring the long-term display effect of the flexible display screen 30. In addition, because the winding and unwinding assembly 10 and the driving module 20 are respectively arranged at two ends of the flexible display screen 30, the winding mechanism of the flexible display screen 30 can be separated from the driving unit, the complexity of the structure and the circuit of the flexible display screen assembly is reduced, the stability of the product is improved, and the early-stage production and the later-stage maintenance of the product are facilitated. 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.
