Patent ID: 8081151

Claim:
A driver controller for controlling a plurality of data driver modules included in a display panel, the driver controller comprising: a clock generation section for generating and outputting a system clock to be supplied to a signal processing section and a plurality of clocks with different phases and with a same frequency; driver-data output clock selection sections, each for selecting one of the plurality of clocks with different phases and with the same frequency received from the clock generation section and outputting a driver data output clock; driver-clock output clock selection sections, each for selecting one of the plurality of clocks with different phases received from the clock generation section and outputting a driver clock output clock; driver data control sections, each for selecting either a data signal from the signal processing section or latch data obtained by latching the data signal by an associated one of the driver data output clocks and outputting, as driver data, the selected data signal or the selected latch data to an associated one of the data driver modules; driver clock control sections, each for outputting a driver clock in synchronization with either the system clock or an associated one of the driver clock output clocks during a time period in which an output enable signal from the signal processing section indicates an active state, the output enable signal indicating a validity period of the data signal and being received from the signal processing section; and a register control section for controlling driver-data-output-clock selection signals for selecting the driver data output clocks and driver-clock-output-clock selection signals for selecting the driver clock output clocks, wherein output timing of the respective driver data and output timing of the respective driver clocks to the data driver modules are individually phase-adjusted for the associated driver data output clock and for the associated driver clock output clock, respectively.
