Patent ID: 8368631

Claim:
A driving integrated circuit (IC), comprising: a memory storing data for driving a panel of a display device and having a memory structure including at least one cell block; a scan register receiving data read from the memory and latching the received read data; a source driver receiving latched data output from the scan register and outputting gradation data to the panel; a switching unit selectively establishing a connection between an activated cell block and the scan register in response to an activation of the activated cell block, the activated cell block included among the at least one cell block of the memory; and a control signal generator controlling whether the switching unit connected to the activated cell block is switched; wherein the switching unit is switched after a given delay period subsequent to a data sensing operation being performed to transmit a voltage to the scan register at a level that supports a data operation, and wherein the control signal generator generates a control signal for switching the switching unit in response to a first signal including sense amplifier operation completion information, a second signal including information associated with the activated cell block, and a scan clock signal.
