US 7,710,370 B2 · Flexible display device rollable between rolled-up and unrolled states

Abstract

The invention relates to a display device assembly (1) comprising a flexible display device (2) being rollable around an axis (5), the flexible display (2) having a front side (3) and a back side (4), one of the sides (3,4) being provided with distance elements (7, 7′,80) for preventing a direct contact between the front side (3) and the back side (4). By preventing the front and back side to contact each other the amount of display damage is significantly reduced as compared to conventional roll-up displays. An advantageous embodiment comprises a display device assembly in which the spacer elements are shaped in the form of bars (7, 7′). In a further advantageous embodiment of the display assembly the distance elements comprise a protection foil (80).

A display device assembly comprising:

a flexible display being rollable around an axis, between a rolled-up and an unrolled state, the flexible display having a front side and a back side,
distance elements provided on one of the sides of the flexible display for preventing a direct contact between the front side and the back side of the flexible display, the distance elements comprising bars positioned to extend substantially parallel to the axis, and
a continuous layer of flexible material positioned between the bars and the back side of the flexible display, and wherein the continuous layer of flexible material is integrated with the flexible display to create hinges between adjacent ones of the bars such that, in the unrolled state of the flexible display, abutting sides of adjacent ones of the bars provide a stiffened support structure for the flexible display.
