Display arrangement with improved drive

Claim 1

A display arrangement comprising two spaced supporting plates with at least one of said two plates being transparent, an electro-optical medium disposed between said two plates, an array of picture elements disposed between each facing surface of said two plates, said array being disposed in rows and columns, a plurality of picture electrodes disposed on each said facing surface, said plurality of picture electrodes defining said array of picture elements, an array of row and column electrodes for driving said picture elements, said row and column electrodes being disposed at least adjacent to said picture elements, wherein said row electrodes are disposed on a facing surface of one of said two plates and said column electrodes are disposed on a facing surface of another of said two plates, and at least a pair of asymmetrically non-linear switching elements being disposed in series with each picture element between one of said column electrodes and two successive row electrodes, each of said asymmetrically non-linear switching elements being disposed between one of said picture electrodes and each of said successive row electrodes, wherein each two successive picture elements are disposed in a column with a common row electrode therebetween, and wherein each of said two successive picture elements are connected by said each asymmetrically non-linear switching element to said common row electrode, said each asymmetrically non-linear switching element being biased in the same direction when viewing from said common row electrode to each opposite row electrode associated with said two successive picture elements.
