Abstract:
A liquid crystal driving device, comprising:a matrix-type liquid crystal display panel, having pixels that are disposed in row and column directions in a matrix, for displaying 2k tones (k being a natural number); a display memory, which stores display data to be supplied to said matrix-type liquid crystal panel; a column driver of m outputs (m being a natural number); a row driver of n outputs (n being a natural number); display memory control means for varying a value n and a value k of mÃ—nÃ—k bits, which is a capacity of said display memory, while holding nÃ—k bits of mÃ—nÃ—k bits constant; and output number setting means for setting a number of outputs of said row driver such that the n value varied by said display memory control means becomes the number of outputs of said row driver.
