ABSTRACT:
An output circuit for gray scale control includes a low-side current mirror unit, a low-side gray scale control circuit, a high-side current mirror unit, a high-side gray scale control circuit, a current increment control circuit and a selective precharge control circuit. A gray scale control circuit for outputting gray scale signals is separated into the high side and the low side, thereby enabling the output-current characteristics to be controlled to be close to the γ characteristics of a light emitting device. In addition, variations in the current for each output unit can be suppressed by using multistage current mirrors.
