Rollable digital blind and control method thereof

Abstract

A rollable digital blind comprises: a screen including a flexible display panel which displays an image and comprises a flexible material, and a flexible solar panel which is overlappingly disposed at one surface of the flexible display panel; a cylindrical-shaped roller which is rotated to wind the screen thereon or unwind the screen therefrom; a housing in which the roller is accommodated; a battery which is charged through the flexible solar panel; a drive unit which is supplied with power from the battery to rotate the roller; a composite photosensor which senses sunlight; and a control unit which, if the composite photosensor senses sunlight, controls the drive unit to unwind the screen and charge the battery through the solar panel. The rollable digital blind not only serves as a blind, but can also be used as a display for outputting an image.
