    Abstract: A display apparatus includes a substrate including a display area, a peripheral area surrounding the display area, a function-adding area, of which at least a portion is surrounded by the display area, and a detour area disposed between the display area and the function-adding area. The display apparatus includes a plurality of pixel circuits disposed in the display area. A plurality of driving lines are electrically connected to the pixel circuits and extend in a direction in the display area. A first detour line is disposed in the detour area and is electrically connected to a first driving line. A second detour line is disposed in the detour area. The second detour line is electrically connected to a second driving line and is disposed in a different layer from the first detour line.

    Abstract: An emission control driver includes a plurality of stages. Each stage includes three circuit blocks and two output transistors. A first circuit block generates first and second control signals based on a first clock signal and a start signal or carry signal. A second circuit block controls the voltage level of the first control signal based on the first control signal and a second clock signal. A third circuit block generates a third control signal based on the second control signal and the second clock signal. The first output transistor outputs a first voltage as an emission control signal based on the first control signal. A second output transistor outputs a second voltage as the emission control signal based on the third control signal. The second circuit block maintains the voltage level of the first control signal while the first output transistor is turned off.

    Abstract: An emission driver includes a plurality of circuit stages to output emission control signals. Each circuit stage includes signal generators, a pull-up controller to control a pull-up circuit, and a pull-down controller to control a pull-down circuit. One signal generator generates node signals based on a carry signal and a second clock signal. Another signal generator generates a first clock signal delayed from the second clock signal and another node signal. The pull-up circuit pulls up an emission control signal to a first driving voltage based on some of the node signals. The pull-down circuit pulls down the emission control signal to a second driving voltage lower than the first driving voltage. The pull-down controller control the pull-down circuit based on delayed dimming clock signals.
