Abstract
An emission driver and a display device having the same are disclosed. In one aspect, the emission driver includes a plurality of stages each configured to output an emission control signal, wherein each of the stages includes first and second driving blocks and a buffer block. The buffer block is configured to selectively output an emission control signal so as to operate in a sequential emission mode or in a simultaneous emission mode, the stages being configured to sequentially output a plurality of the emission control signals in the sequential emission mode and substantially simultaneously output the emission control signals in the simultaneous emission mode. The buffer block is further configured to determine a duration in which the emission control signal has a first voltage level based on an interval between time points when first and second intermediate signals have low voltage levels.
