Patent ID: 8692745

Claim:
A driver for driving a plurality of pixels formed by data lines and scan lines, the driver comprising: a controller for receiving a plurality of display data, detecting whether or not same display data are input during a predetermined period, providing a first control signal and display data corresponding to a pre-stored protecting image to a data driving circuit when the same display data are detected during the predetermined period and a second control signal when the same display data are not detected during the predetermined period, and transmitting the plurality of display data; the data driving circuit for transmitting data current corresponding to the plurality of display data transmitted from the controller to the data lines; a scan driving circuit for driving the scan lines in accordance with the first and second control signals from the controller, all of the scan lines being connected with the scan driving circuit, the scan lines in a display part being sequentially driven by a unit of two or more adjacent lines when the first control signal is supplied to the scan driving circuit, the scan lines in the display part being sequentially driven by a unit of one line when the second control signal is supplied to the scan driving circuit; and a power supply providing circuit for supplying a scan driving voltage to the scan driving circuit, and controlling duty ratio of the scan driving voltage such that a brightness of a display data is low only when the same display data are detected during the predetermined period, wherein driven periods of the two or more adjacent lines are synchronized with each other only when the first control signal is supplied to the scan driving circuit, wherein the two or more adjacent lines comprises a first line and a second line, wherein the second line is connected with all pixels arranged between the first and the second lines, wherein the scan driver simultaneously supplies only a same scan signal to the scan lines that are driven by the unit of two or more adjacent lines, the same scan signal being supplied for a same period, and wherein the same scan signal is supplied to pixels connected with the two or more adjacent lines in the display part.
