Abstract:
A driving device comprising:an imaginary data generating means, a row electrode driving means, a column electrode driving means, a memory means for memorizing display data, an operating means for operating column output voltages, and a row selection pattern generating means for outputting a row selection pattern; wherein: a kÂ·m number (k is an integer not less than 2 and m is an integer not less than 1) of simultaneously selected/driven rows and a kÂ·n number (n is an integer of not less than 1) of imaginary row are determined for a liquid crystal display element including row electrodes and column electrodes arranged in a matrix form and the display element is driven by a multiple line addressing (MLA) driving method, and a matrix B is used for a row selection pattern, which is formed by expanding a matrix A of (m+n) rows where row vectors perpendicularly intersect each other, and column output voltages are operated in accordance with contents of the matrix A.
