Abstract
The display device of the invention comprises a flexible display element that can be extended in rollable fashion between a first position and a second position. In the first position the element is present in a housing and in the second position it is at least partially visible. The display element is supported in its second position by foldable arms. According to the invention a foldable arm comprises means which facilitate the extension of the display from the first to the second position and from the second position to a further position. These means also counteract any tendency of the display to return by itself from the second or any further position to the first position.
Claims9
A display device comprising:
- a display which is flexible and which may be present in both a first position and a second position, in which in the first position the display is at least largely rolled up around a shaft in a housing and in which in the second position at least part of the display is visible,
- extension structure to facilitate extending the display to the second position,
- wherein the extension structure comprises means for generating an extending force acting in an opposite direction with respect to a force driving the display towards the first position upon a transition towards the second position, the extension structure further arranged to counteract a tendency of the display to return by itself from the second position to the first position by balancing, in the second position, the extending force and the force driving a display towards the first position when in the second position, and
- wherein locking means are present with which the display can be locked in at least one position.
