The flexible display device provided by the embodiments of the present invention combines sensor technology with flexible display, and can automatically switch between different functions according to the length of the flexible display screen pulled out from the drum.

In order for those skilled in the art to better understand the flexible display device provided by the embodiments of the present invention, the flexible display device provided by the present invention will be described in detail below through specific embodiments.

This embodiment specifically provides a portable flexible display device that integrates photography, video recording, video playback and audio playback, and uses sensors installed on the frame of the flexible display screen to realize switching between functions.

Specifically, as shown in Figures 1 and 2, the flexible display device includes a cylinder-shaped housing 20 with invisible control components and rollers (not shown in the figure), and the flexible display screen 10 rolls Wrapped on the drum, and can be unfolded from the drum; a transparent window 22 is provided on the shell 20 (the side of the cylinder), and a part of the display area of the flexible display 10 can be seen from the transparent window 22; the transparent window on the shell 20 The top of the window is provided with a camera 25 and a second button module 23 for controlling photographing and video recording, and the bottom of the transparent window is provided with a first button module 21 for controlling video and audio playback; a bottom surface of the shell 20 is provided with Power switch 26, audio input interface (such as microphone MIC27) and audio output interface (such as earphone jack 28), the other bottom surface is provided with USB interface 24, USB interface 24 can complete data transmission and charging functions.

Three sensors (sensor 12 , sensor 13 and sensor 14 ) are arranged on the flexible display screen 10 along the unfolding direction, respectively located at the first position, the second position and the third position on the flexible display screen 10 . For example, preferably, the flexible display screen 10 includes a frame 11, and the sensor 12, the sensor 14 and the sensor 13 are arranged on the frame, and are respectively located at the starting end, the farthest end, and somewhere between the starting end and the farthest end when the flexible display screen 10 is unfolded. in one position. The casing 20 is provided with an invisible control component, which includes a switching unit for switching the function of the flexible display device according to the switching signal, and is connected with the sensor.

As shown in FIG. 3, when the flexible display screen 10 is expanded to the maximum, the sensor 14 at the farthest end is activated to output a switching signal, and the switching unit of the flexible display device automatically switches to the video playback mode according to the switching signal. For video, various display parameter settings are also automatically adjusted according to the video mode; as shown in Figure 4, when the flexible display screen 10 is unfolded to a certain position in the middle, the sensor 13 set at this position is activated to output a switching signal, and the switching unit according to This switching signal is automatically switched to the picture browsing mode, and the display area in Figure 4 can be used for picture browsing, and various display parameter settings are adjusted according to the picture browsing mode; as shown in Figure 5, when the flexible display screen 10 is not unfolded, the sensor at the starting end 12 is activated to output a switching signal, and the switching unit automatically switches to the audio playback mode according to the switching signal. At this time, the display area is the corresponding area below the transparent window in Figure 5, and the display parameters are adjusted according to the audio playback mode.

Further optionally, the flexible display device may also include: a control unit (not shown in the figure, the control unit is also an invisible control component) for controlling the display content of the area corresponding to the transparent window 22 on the flexible display 10 part of the), connected to the switching unit. In this embodiment, the area corresponding to the transparent window 22 on the flexible display 10 specifically refers to the part of the display area that can be viewed from the transparent window 22 on the flexible display 10, or the part of the flexible display 10 that leaks from the transparent window 22. That part shows the area. It should be noted that the area corresponding to the transparent window 22 is not fixed. When the length of the flexible display 10 is different, the position of the area corresponding to the transparent window 22 on the flexible display 10 will also change accordingly.

The control unit is dedicated to controlling the display content in the area corresponding to the transparent window 22 on the flexible display 10, and is connected to the switching unit, which can display the current functional mode of the flexible display device in this area (corresponding to the transparent window 22). Corresponding information, for example: if the display flexible display device is switched to the audio playback mode, the flexible display area at the corresponding position below the transparent window 22 is automatically activated to display relevant information about playing audio, such as artists, albums, playlists, and lyrics. If the display flexible display device is switched to the video playback mode, the flexible display area at the corresponding position below the transparent window 22 is automatically activated to display relevant information about playing videos.

Optionally, the area corresponding to the transparent window 22 and the area corresponding to the transparent window 22 can also display system information, or other information that needs to be displayed according to the function of the flexible display device, such as power, communication signal strength, calendar, time , To-Dos, Mail, and more.

Further, as shown in FIG. 5 and FIG. 6 , the flexible display device may further include: a switching button module 32 for forcibly switching functions of the flexible display device, connected to the switching unit 30 . The switching button module 32 can also be arranged above or below the transparent window 22 like the first button module 21 and the second button module 23 . The switching button module 32 forcibly switches the function of the flexible display device according to user input, and this operation will override the automatic switching action generated by the sensor 12 .

Alternatively, the flexible display device can also be provided with an activation button 33 for turning on or off the sensor. The activation button 33 is connected to the sensor and can be arranged on the outer side of the initial end of the flexible display 10, as shown in FIG. 5 .

Figure 6 is a schematic diagram of the connection relationship of the various control components involved in the embodiment of the present invention. On the one hand, the switching unit 30 is connected to the switching button module 32 and the sensor 14 (there may be multiple, represented by the sensor 14 here). On the one hand, it is connected to the control unit 31 . The switching unit 30 automatically switches the function of the flexible display device according to the signal of the sensor 14, and at the same time, when the user inputs through the switching button module 32, the function switching is forced; The area below the transparent window 22 on the casing 20 displays information corresponding to the functions of the flexible display device.

As shown in FIG. 7 , it is a schematic structural diagram of another flexible display device provided by the embodiment of the present invention. The difference from the flexible display device shown in FIG. 1 is that the sensor 14 is a distance sensor, and only one is required. It is arranged on the starting end of the flexible display screen 10 (such as the inner side of the starting end). The distance sensor obtains the unfolded length of the flexible display screen 10 by detecting the position from the starting end to the corresponding point of the casing.
