    Abstract: An organic light-emitting display apparatus includes an organic light-emitting diode, a switching transistor, a first light emission control transistor, and a driving transistor. The organic light-emitting diode includes an anode and a cathode for receiving a reference voltage. The switching transistor includes a gate electrode for receiving an nth scan signal and a source electrode for receiving a data signal, and is an NMOS transistor. The first light emission control transistor includes a gate electrode for receiving a light emission control signal, and is configured to turn on upon receiving the light emission control signal to determine a timing of flow of a driving current to the organic light-emitting diode, and is a PMOS transistor. The driving transistor is connected to the switching transistor and the first light emission control transistor and provides the driving current to the organic light-emitting diode.

    Abstract: There is provided a scan driver. The scan driver includes stages. An ith (i is a natural number) stage circuit includes an output unit, a controller configured to control the voltage of the second node in response to a kth (k is a natural number) clock signal supplied to a second input terminal, and an input unit configured to control the voltages of the first node and the second node in response to a carry signal of a previous stage that is supplied to a third input terminal and a carry signal of at least one next stage. The kth clock signal maintains a gate on voltage at a point of time at which a voltage of the jth clock signal is changed to a gate on voltage.

    Abstract: An illumination apparatus includes a main light source, a half minor, and a diffusion plate. The main light source emits main light. The half mirror is spaced apart from the main light source. The half mirror reflects a first light travelling in a first direction among the main light source. The half mirror has a reflective surface reflecting the first light to travel in a second direction. The diffusion plate is disposed between the main light source and the half mirror not overlapping the reflective surface. The diffusion plate has a first horizontal surface and a second horizontal surface. The second horizontal surface is a rear surface of the first horizontal surface. The diffusion plate transmits a second light incident on the first horizontal surface among the main light. The diffusion plate scatters the second light from the second horizontal surface.
