DATA DRIVING CIRCUIT AND DRIVING METHOD OF LIGHT EMITTING DISPLAY USING THE SAME

摘要

A data driving circuit, a light emitting display using the same, and a driving method thereof are provided to display uniform images by supplying a data signal generated in a DAC(Digital-to-Analog Converter) different from a DAC of the preceding horizontal period, to data lines in every horizontal period. A data driving circuit(600) includes a holding latch unit(603) having plural holding latches(6031~603j) storing data(Data); a signal generating unit(605) having plural digital-analog conversion units(6051~605h) generating a data signal by receiving the data; a first switching unit(604) installed between the holding latch unit and the signal generating unit; and a second switching unit(606) connected to the signal generating unit to transmit the data signal to data lines. The first switching unit differently connects the holding latch units with the digital-analog conversion units, respectively during the present horizontal period.
