Abstract
An emission selection driver includes an emission driver configured to output an emission signal from an emission output node, and a selection driver connected to the emission output node and configured to output a selection signal based on a next emission signal and an enable signal.
Claims21
An emission selection driver comprising:
- an emission driver configured to output an emission signal from an emission output node;
- and
- a selection driver connected to the emission output node and configured to output a selection signal based on a next emission signal and an enable signal,
- wherein the selection signal outputs a first level when the next emission signal and the enable signal have the first level, and
- wherein a pulse of the selection signal and a pulse of the emission signal are equal in duration and timing.

An emission selection driver comprising:
- an emission driver configured to output an emission signal from an emission output node;
- and
- a selection driver connected to the emission output node and configured to output a selection signal based on a next emission signal and an enable signal,
- wherein the selection driver includes:
- a first selection transistor including a gate electrode connected to a selection control node, a first electrode receiving the emission signal, and a second electrode outputting the selection signal;
- a second selection transistor including a gate electrode receiving the next emission signal, a first electrode receiving the enable signal, and a second electrode connected to the selection control node;
- and
- a selection capacitor including a first electrode receiving the emission signal and a second electrode connected to the selection control node.
