Abstract
The present invention provides a driving circuit of a flat display device and a flat display device, and it is applicable, for example, to a display device using organic EL (Electro Luminescence) elements. The present invention makes it possible to correct light emission characteristics variously, effectively avoid significant degradation in image quality due to noise, and further simplify an adjustment operation by generating original reference voltages by selecting a plurality of candidate voltages formed by voltage divider circuits according to original reference voltage setting data, generating reference voltages for digital-to-analog conversion from the original reference voltages, generating the reference voltages at both ends by dividing a reference voltage generating voltage by the voltage divider circuit, and generating the other original reference voltages with voltage divider circuits connected in series with each other and the reference voltages at both ends used as a reference.
