Referring to FIG. 2, the power supply unit 400 is connected to a cigar jack port of a vehicle (not shown) as a cigar jack plug to receive battery power from a vehicle.

The adjustment switch 500 is a two-way switch that allows the drive motor 301 to rotate forward and backward to facilitate the winding of the display film 370 or the retraction of the display film 370 to the home position .

Next, operation and effect of the display film 10 according to the present invention will be described with reference to the drawings.

First, the power supply unit 400 is connected to a cigar jack port (not shown) of the vehicle, and then the control motor 500 is operated by pressing the control switch 500.

A plurality of pinion gears 217 provided on the first support member 210 are rotated in accordance with the rotation of the driving gear 303 provided at the front end of the driving motor 301, The internal gear 311 formed on the inner periphery of the first winding member 310 of the winding means 300 rotates and the display film 370 wound on the film paper tube 350 is deployed.

At this time, the drive motor 301 operates only when the control switch 500 is depressed. When the display film 370 is drawn out and the control switch 500 is released, the electromagnet It stops immediately by the brake.

As shown in FIG. 6, when the display film 370 is deployed, users in front and rear seats may view the DMB or selectively use navigation or other audio. When the display film 370 is used, The display film 370 which has been developed by pressing the adjustment switch 500 in the reverse direction is returned to its original state and wound.

As described in detail above, according to the roll screen type flexible display device of the present invention, the flexible display can be folded like a scroll and stored while being used, so that the flexible display can be taken out and used, .

Furthermore, not only the driver in front of the vehicle but also the users who are seated in the rear seat can easily hang up the front seat backrest and use the DMB, thereby maximizing the utilization.

Furthermore, the display device can be operated with a single button, thereby maximizing the convenience of the rear seat user as well as the driver.

As described above, the roll screen type flexible display device 10 according to the present invention can be used for a sunshade or a mirror film in addition to the use of the DMB watching or navigation by the above-mentioned display film, Of course.

It is to be understood that the present invention is not limited to the specific exemplary embodiments described above and that various modifications may be made by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims. And such modified embodiments are within the scope of the claims of the present invention.
