Abstract: An information display apparatus is described comprising an array of staggered electromagnets (1) arranged vertically on a carriage (2). In between the carriage (2) and a mesh frame (3) are a pair of stainless steel metal shields (4) having a castellated form, the electromagnets (1) being located in recesses formed by the castellations. The mesh frame (3) supports rotatable flags (5) which have two contrasting coloured faces. To prevent stray magnetic flux from an energised electromagnet actuating a flag (5) above and/or below the intended flag (5), to be actuated a pair of castellated shields (4) is located between the electromagnets (1) and flags (5). An improved supporting mesh frame (18) comprises moulded rectangular plastics strips (9) having spaced holes (10). The strips (9) are joined by metal rods (11) which fit in the holes (10) forming a mesh support for the flags (5) which rotate about the rod (11).

Abstract: A spatial light modulator formed of a moveable electrode (30) which is disposed opposite a fixed electrode (12) and is biased to roll in a preferred direction upon application of an electric field across the electrodes to produce a light valve or light shutter. In one embodiment, the moveable electrode is restrained at one end and coils about the fixed end in a preferential roll direction. The bias is achieved by inducing anisotropic stress or anisotropic stiffness.

Abstract: A high-resolution display has a membrane (1) into which are incorporated pivoting flaps (2) which can be individually controlled by means of a control device. The pivoting flaps (2) have two wings (5 and 6) centrally interconnected by a tapering rod (7). The rod (7) is linked to the membrane (1) by torsion bars (3 and 4) located in the axis of rotation of the pivoting flap (2) between the wings (5 and 6) in such a way that the torsion bars lie substantially within the outer perimeter of the pivoting flaps (2), so that even when long torsion bars (3 and 4) are used, pivoting flaps may be compactly arranged next to each other.

Abstract: An electromechanical binary element is provided for uses such as display arrays. The binary element has a moveable flap having at least a conductive surface. The flap is electrostatically controllable between a position removed from a stator member having stationary electrodes, and a position overlying the stator member to modify the light reflective or transmissive character of the binary element when used as a display. The conductive surface of the flap is electrically isolated from the stationary electrodes. Stationary electrodes having a plurality of discrete conductive regions are provided to facilitate the control of elements in an array. Connection of a source of electrical potential between stationary electrode regions provides electrostatic force to attract the flap.
