WIPO Patent Application WO/2021/251532
Kind Code:
A1
Abstract:
Disclosed is a display device. The display device according to the present disclosure may comprise: a flexible display panel; a roller on and from which the display panel is wound and unwound; a base which extends in the longitudinal direction of the roller and on which the roller is rotatably installed; a link mount which is supported by the base; a link pivotably connected to the link mount so as to lift and lower the display panel; a pivot magnet fixed to the pivot center of the link; a magnetic sensor for sensing the position of the pivot magnet; and a control unit for adjusting the movement of the link. When the position zone of the pivot magnet is divided into an effective position zone (Ieff) and an error position zone (Ierr), the position of the pivot magnet changes within the effective position zone. The control unit can calculate information about the angle formed by the link with respect to the base from information about the position of the pivot magnet, and adjust the movement of the link on the basis of the information about the angle.
