The present invention generally relates to display devices with a flexible display. The present invention specifically relates to display devices of the kind comprising a device body, a continuous flexible display, an elongated support frame configured to support the flexible display, being provided with mutually movable connected frame portions and being hingeably connected at a first end to the device body between a closed configuration for fixing the flexible display in a wrapped storage position with respect to the device body and an open configuration for fixing the flexible display in an unwrapped open position,
DESCRIPTION OF PRIOR ARTMobile display devices, such as mobile phones or e-readers, which make use of flexible displays have in their storage position a compact state, for instance for transportation, previewing or phone calls. In the open position they are in a reading/viewing state with the continuous flexible display in extended position supported by an elongated support frame.
A number of product concepts have been developed for devices with flexible displays. One of the most important concepts is the ‘wrap’. An example of a ‘wrap’ concept is shown in WO 2008/054206 A2. When the flexible display is wrapped for the storage position this is done with its front side to the body. The reason is that the display is better protected this way when the device is not in use. In the storage position the support frame of this ‘wrap’ type display is closed and locked by mechanical means, requiring a special handling which in practice, in combination with the handling for opening, is user unfriendly.
The use of closing means for a ‘wrap’ type display device applying magnetic force is difficult because the device design is very lightweight and flexible resulting in deformation of the frame portions when opening the device. Another problem is the exact position and angle of the magnet that is required for an optimal closing force. This demand for a precise position and angle is required in order to let the magnetic fields couple most optimal with the metal or magnetic counter part. The use of a stronger magnet to compensate for less accuracy is not an option since this could result in the magnet erasing bank cards when they are close to the display device.
It is an object of the invention to create a user friendly closing, locking and opening of a ‘wrap’ type flexible display.
DISCLOSURE OF THE INVENTIONAccording to the invention the display device comprises magnetic closing means being provided with a first locking part being movably connected to a major part of the support frame, said magnetic closing means being capable of magnetically locking a second end of the support frame in the closed configuration to the device body and being provided with at least one unlocking member enabling a manual unlocking of said second end of the support frame from the device body.
Preferably the magnetic closing means with its locking part can relatively freely move in the closed configuration with respect to the support frame and as such it can find the optimal locking position, where the magnetic field of the used magnet is coupled most optimal with its static counterpart (metal or magnet) and as such is also able to compensate for mechanical inaccuracies resulting e.g. from assembly or wear in the support frame with its movable frame portion and its hinge connection with the device body. At the same time the at least one unlocking member allows the user to unlock and turn the magnet away from its counterpart so breaking the magnetic coupling and resulting in opening the support frame and the flexible display with little force. It is noted that the magnet may be an integrated portion of the locking part or of the counterpart located on the device body.
According to a preferred embodiment of the invention said first locking part is pivotably connected to the second end of the support frame, the pivot axis of the connection being located substantially parallel to the hinge axis in the connection of the first end of the support frame with the device body.
Thus the magnet is assembled on the locking part that can relatively freely pivot around the pivot axis located parallel to the hinge axis in the connection of the first end of the support frame with the device body to find a position where the magnetic field of the magnet is coupled most optimal with its static counterpart (metal or magnet) also able to compensate for support frame assembly or other mechanical inaccuracies.
According to another preferred embodiment of the invention said first locking part is connected by a ball hinge with the second end of the support frame. The ball hinge enables that the locking part can relative freely move in its connection with the second end of the support frame to find a position where the magnetic field of the magnet is coupled most optimal with its static counterpart (metal or magnet). The ball hinge also enables a good compensation for support frame mechanical inaccuracies resulting e.g. from assembly or wear.
According to still another preferred embodiment of the invention the unlocking member comprises a grip portion. The grip portion allows the user to turn the magnet away from its counterpart so breaking the magnetic locking and resulting in opening the support frame with little force.
