A logic circuit comprising a logic sub-circuit arranged to output a stream, S1, of Fresnel lens values, F(x), of a Fresnel lens for display on [mxn] pixels of a pixelated display device, wherein the logic circuit is arranged to: set an initial data value stored in a first data register unit and set an initial data value stored in a second data register unit; in an iteration, reading the data value stored in the first data register unit and the data value stored in the second data register unit, summing the data value read from the first data register unit and the data value read from the second data register unit to form x2 to calculate F(x) as the next value in the stream of F (x) values; writing x2 to the first data register unit, adding 2k2 to a value stored in the second data register unit, and performing further iteration. 一种逻辑电路，包括逻辑子电路，其布置为输出菲涅耳透镜的菲涅耳透镜值F(x)流S1，以在像素化显示设备的[m×n]个像素上显示。其步骤包括设置第一数据寄存器单元中的初始数据值和第二数据寄存器单元中的初始数据值；在迭代中分别读取第一数据寄存器单元中和第二数据寄存器单元中的数据值，将从第一数据寄存器单元读取的数据值与从第二数据寄存器单元读取的数据值求和，以形成x2来计算F
