Abstract

A display or light-modulating device incorporates one or more measures of liquid that obstruct or filter light that passes onto or through the liquid; a space distribution of different light-modulating filters, optical instrument or materials or of materials that change the frequency or color of light passing onto or through them, to emit a different frequency or color of light; and means to apply electrowetting effect to controllably modulate the location or shape of one or more measures of a polar or conductive liquid, so that at least some portion of one or more light-obstructing or light-filtering measures of liquids is caused to be located between one or more light sources and the space distribution of light-modulating filters, optical instruments or light-modulating materials, or said space distribution of materials that change the frequency or color of light passing onto or through them, to emit a different frequency or color of light, thereby controllably modulating properties of light emitted from said device.

Claims

1. A display or light-modulating device, incorporating:

one or more measures of liquid which serve to obstruct the passage of light, or which filter light which passes onto said measure(s) of liquid;

a space distribution of different light-modulating filters, optical instrument or materials;

or a space distribution of materials which convert or change the frequency or color of light passing onto or through them, to emit a different frequency or color of light;

means to apply electrowetting effect to controllably modulate the location or shape of one or more measures of polar or conductive liquid, so that at least some portion of one or more light-obstructing or light-filtering measure of liquids is caused to be located between one or more light sources and said space distribution of light-modulating filters, optical instruments or light-modulating materials, or said space distribution of materials which convert or change the frequency or color of light passing onto or through them, to emit a different frequency or color of light, thereby controllably modulating properties of light emitted from said device.
