Patent ID: 7116301

Claim:
A driving device for driving an electro-optic device including electro-optic elements capable of outputting R gradations of brightness (R being an integer not less than 2), the electro-optic elements being provided for each combination of a plurality of scanning lines and at least one data line, the driving device comprising: a driving section for supplying instruction data to the electro-optic elements corresponding to the scanning line currently selected among the plurality of scanning lines sequentially selected, the driving section supplying the instruction data to the electro-optic elements via the data lines corresponding to the electro-optic elements, the instruction data for controlling outputs of the electro-optic elements for a period until subsequent instruction data is supplied, the driving section supplying instruction data A times (A being an integer not less than 2) in one frame period to each electro-optic element so as to control outputs thereof in the one frame period, each instruction data having a weight selected from A predetermined weights, such that the weight of at least one instruction data of the instruction data in each frame period is different from the weight of an immediately previously supplied instruction data and different from the weight of an immediately subsequently supplied instruction data, weights of the instruction data contributing to the outputs in the one frame period are set such that R A >B where B is a number of brightness levels displayable in the one frame period by a combination of the A weights of instruction data being supplied to the electro-optic elements in the one frame period, and each difference in brightness between adjacent brightness levels among the B brightness levels is the same.
