Patent ID: 8537093

Claim:
A source driver of a display device comprising: a plurality of level shifters including a first level shifter for raising a voltage level of a first digital image signal and a second level shifter for raising a voltage level of a second digital image signal; a plurality of digital-to-analog converters including a first digital-to-analog converter for converting the first digital image signal to a first analog image signal and a second digital-to-analog converter for converting the second digital image signal to a second analog image signal; a plurality of output circuits including a first output circuit for receiving the first analog image signal and outputting a first source line driving signal and a second output circuit for receiving the second analog image signal and outputting a second source line driving signal; and a plurality of control circuits including a first control circuit for generating a first control signal and controlling the first output circuit with the first control signal and a second control circuit for generating a second control signal and controlling the second output circuit with the second control signal, the first control circuit being configured to receive a switch signal and generate a first set of delayed switch signals by delaying the switch signal, the first control circuit being configured to select one signal among the switch signal and the first set of delayed switch signals in response to a first selection signal and output the selected signal as the first control signal, the second control circuit being configured to receive the switch signal and generate a second set of delayed switch signals by delaying the switch signal, the second control circuit being configured to select one signal among the switch signal and the second set of delayed switch signals in response to a second selection signal and output the selected signal as the second control signal.
