Abstract:
1. A liquid crystal driving apparatus comprising: a latch circuit including a plurality of latch areas each in n-bit unit, the latch circuit being configured to sequentially latch a plurality of pieces of n-bit display data into a designated latch area of the latch areas, the plurality of pieces of n-bit display data being obtained by dividing m-bit display data for driving column electrodes corresponding to each of row electrodes of a liquid crystal display panel including a plurality of the row electrodes and a plurality of the column electrodes; a data register configured to sequentially hold the plurality of 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, the latch pulse generating circuit including: the column electrodes being driven based on the m-bit display data output from the latch circuit.
