Abstract:
1. A driving IC for driving elements, comprising: a drive circuit that produces drive signals for driving n elements based on n data signals constituting a group of data signals; x-stage latch circuits (where x is an integer equal to or greater than 2) that each store one of x groups of data signals and that are connected in series with one another; a strobe control circuit that produces y strobe signals for determining timing with which data signals corresponding to the individual elements are fed to the drive circuit; and a select circuit that selects the data signals corresponding to the individual elements from the x-stage latch circuits to produce one group of data signals from the n data signals, and that feeds the individual data signals constituting that one group of data signals to the drive circuit in synchronism with the y strobe signals fed from the strobe control circuit.
