ABSTRACT:
A liquid crystal driving apparatus comprising: a latch circuit including latch-areas each in n-bit unit, configured to sequentially latch into a designated latch-area, pieces of n-bit display-data obtained by dividing m-bit display-data for driving column-electrodes corresponding to each row-electrode of a liquid crystal display panel including row and column-electrodes; a data-register configured to sequentially hold the pieces of n-bit display-data; and a latch-pulse generating circuit configured to generate a latch-pulse for latching the n-bit display-data into the designated latch-area every time the data-register holds the n-bit display-data, including: a counter whose count-value changes every time the data-register holds the n-bit display-data; a decoder configured to decode the count-value to generate the latch-pulse; and a masking circuit configured to mask generation of the latch-pulse from the decoder in a period of time during which the count-value is changed, the column-electrodes being driven based on the m-bit display-data from the latch circuit.
