Display device and system

A logic circuit comprises a logic sub-circuit arranged to output a stream, S1, of Fresnel lens values, F(x), of a Fresnel lens for display on [m×n] pixels of a pixelated display device, and an iterative method outputs a stream, S1, of Fresnel lens values, F(x), of a Fresnel lens for display on [m×n]...

More Information
Summary:A logic circuit comprises a logic sub-circuit arranged to output a stream, S1, of Fresnel lens values, F(x), of a Fresnel lens for display on [m×n] pixels of a pixelated display device, and an iterative method outputs a stream, S1, of Fresnel lens values, F(x), of a Fresnel lens for display on [m×n] pixels of a pixelated display device. The circuit and method can reduce the number of multiplications used to provide each value of a stream of display values for the display device, wherein the display values include values of a Fresnel lens function. Accordingly, they can be implemented in an advanced integrated circuit, such as a field-programmable gate array.
