It is to be understood that the described embodiments are merely illustrative of some, but not all embodiments of the disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any inventive step, are intended to be within the scope of the present disclosure.
The scroll type flexible screen can be arranged on the scroll in a curling manner, so that the screen can be bent randomly, and the scroll type flexible screen is light and thin in material and more convenient to carry. However, when the screen is displayed on the existing scroll-type flexible screen, the display area or size of the screen cannot be adjusted in real time according to the displayed screen, and the display performance of the scroll-type flexible screen is not improved due to poor self-adaptability.
As shown in fig. 1, fig. 1 is a schematic structural diagram of a display device according to an embodiment of the disclosure. The display device includes a rolled screen. The rolled screen includes a reel mechanism 100 and a flexible screen 101.
Wherein the flexible screen 101 is rollably disposed on the reel mechanism 100, the flexible screen 101 is rollably housed on the reel mechanism 100, and when a tensile stress is applied to the flexible screen 101, the flexible screen 101 is uncoiled along the reel mechanism 100 to form an uncoiled region 103.
When the rolled screen is in operation, the flexible screen 101 in the unrolled area 103 displays the display in real time.
Further, the rolling screen provided by the embodiment of the present disclosure further includes a transceiver 102. The transceiver 102 is disposed on both the reel mechanism 100 and the flexible screen 101, and is shown as a structural example only.
When the flexible screen 101 in the rolled screen is unfolded under the action of an external force, the transceiver 102 arranged on the flexible screen 101 sends out an unfolding information parameter, preferably, the transceiver 102 is arranged in a film layer of the flexible screen 101, and when the flexible screen 101 is unfolded, the transceiver can transmit an unfolding information parameter, such as a distance signal, that is, the distance between the transceiver 102 and the central axis of the scroll mechanism 100, and the smaller the unfolded area of the flexible screen 101 is, the closer the transceiver 102 is to the central axis of the scroll mechanism 100, the stronger the signal intensity will be.
The larger the area of deployment, the greater the distance of the transceiver 102 from the central axis of the reel mechanism 100, and the stronger the signal strength. The control unit 1021 arranged inside the rolling screen controls the unfolding area of the unfolding area 103 of the flexible screen 101 in real time according to the signal parameters fed back by the transceiver 102 and the screen size required by the display picture during displaying, so as to provide a better display area.
Preferably, the control unit 1021 rolling the inside of the screen may be disposed at both side edges of the flexible screen 101 of the display device to control the unwinding or winding of the flexible screen 101.
The control unit 1021 can be a transmission mechanism or a pulley mechanism, and can control the expansion of the flexible screen 101 by limiting the expansion, and meanwhile, the control unit 1021 can also control the expansion speed of the flexible screen, and when the expansion speed is too high, the expansion speed can be reduced, so that the flexible screen can be well protected.
When the flexible screen 101 is completely rolled up, the transceiver 102 provided in the reel mechanism 100 and the transceiver 102 provided in the flexible screen 101 are aligned with each other.
The transceiver 102 is configured to transmit and receive information parameters of an unwinding area 103 of the rolled screen unwound along the winding mechanism 100, and the control unit is configured to control the size of the unwinding area 103 of the flexible screen 101, so as to realize real-time control of the unwinding area of the flexible screen 101, provide a better picture display scale, and improve the display quality of the rolled screen.

That is, the distance D is 2 pi r, D represents the distance between two adjacent signal emitting ends 202, and r represents the radius value of the reel mechanism 200.
Specifically, if the display area of the current flexible screen is S1, the distance D between the farthest signal emitting end 202 and the signal receiving end 2021 is measured during the unfolding process, and when the distance D1 is reached, the unfolding area corresponding to the flexible screen 201 is S1, and the unfolding is stopped at this time. And the picture is displayed in the expansion area, thereby ensuring the display effect of the flexible screen.
Meanwhile, the plurality of signal transmitting terminals 202 are connected to each other through the conducting wire 203, the signal transmitting terminal 202 on each side is connected through one conducting wire 203, and the signal transmitting terminals 202 on the two opposite sides can be arranged in a one-to-one correspondence manner. Meanwhile, a pulse control signal or a direct current signal is provided for the display device through a chip in the display device.
The signal emitter 202 emits the distance parameter, and the signal receiver 2021 in the reel mechanism 200 receives the distance parameter.
Specifically, when the flexible screen 201 of the display device is unfolded, the signal emitting end 202 is gradually unfolded together, at this time, the outermost side of the flexible screen 201, that is, the distance parameter between the rightmost signal emitting end of the corresponding flexible screen 201 in fig. 2 and the scroll mechanism 200 is continuously changed, along with the increase of the unfolding area, more signal emitting ends 202 are unfolded, at this time, the signal receiving end 2021 arranged in the scroll mechanism 200 receives various information parameters sent by the signal emitting end 202, such as the distance parameter, the winding or unfolding speed, the time and other parameters, so as to judge the unfolding condition of the flexible screen 201, and finally, the flexible screen 201 is controlled in real time.

The signal emitting end 202 is arranged in the film layer, so that the signal emitting end 202 is arranged under the condition that the thickness of the film layer of the flexible screen is not increased, and the unfolding area of the flexible screen is controlled in real time.
Specifically, the substrate base plate 300 may include a multi-layer film structure, such as a first buffer layer, a first base, a second buffer layer, and a second base, which are sequentially stacked to form the substrate base plate 300.
