Abstract:
A liquid crystal display comprising:a plurality of pixels, each of which is spatially divided to form a first sub-pixel and a second sub-pixel, and;a control arrangement for selectively switching each pixel to an intermediate optical state between a maximum attenuation optical state and a minimum attenuation optical state by switching the first and second sub-pixels to the intermediate optical state,wherein each of the first sub-pixels has input and output linear polarizers whose polarization directions are parallel and each of the second sub-pixels has input and output linear polarizers whose polarizing directions are orthogonal, andthe control arrangement selectively switches each pixel to the intermediate optical state by selectively switching attenuation optical states of the corresponding first and second sub-pixels with their respective parallel and orthogonal input and output linear polarizers as a function of the intermediate optical state.
