FLAT PANEL DISPLAY SOURCE DRIVER CIRCUIT FOR PERFORMING MULTIPLE DRIVING OPERATION WITHIN UNIT SOURCING PERIOD AND A SOURCE DRIVER CIRCUIT USED FOR THE SAME, CAPABLE OF SAVING STANDBY ELECTRIC POWER

摘要

PURPOSE: A flat panel display source driver circuit for performing multiple driving operation within unit sourcing period and a source driver circuit used for the same are provided to save layout are by reducing the number of DAC.;CONSTITUTION: A source driver circuit includes a source driving block(BKSD). The source driving blocks include data supply part(PDP), a digital-to-analog conversion section(PDA), and a driving unit(PDR). The data supply unit supplies α-digital data(R-DGT), β-digital data(B-DGT) and γ-digital data(G-DGT). The digital-to-analog conversion section outputs α-analog data, β-analog data and γ-analog data. The digital-to-analog conversion section includes a first DAC(DA1), a second DAC(DA2) and a third DAC(DA3). The first DAC receives α-group gradation voltages. The second DAC receives β-group gradation voltages. The third DAC receives γ-group gradation voltages. The driving unit includes the first or the third driving unit(DR1,DR3). The first or the third driving unit selectively drives analog data among α-analog data, β-analog data and γ-analog data.;COPYRIGHT KIPO 2010
