Patent ID: 7911423

Claim:
An organic electro luminescence device, comprising: first, second, and third switching elements connected in series with each other, the first switching element controlled by a first signal, and the second and third switching elements controlled by a second signal, the second signal being different from the first signal, wherein the first signal is applied to a gate of the first switching element and the second signal is applied to each of gates of the second and third switching elements; a first driving element connected to a power source, a storage capacitor, and the first, second and third switching elements; and a second driving element connected to the power source, the storage capacitor, an organic light emitting diode, and the third switching element, wherein a gate of the first driving element is directly connected to a node between a drain of the second switching element and a source of the third switching element, wherein a source of the first driving element is connected to the power source, and a drain of the first driving element is connected to a node between the first and second switching elements, and wherein each of the first and second driving elements is directly connected to the power source.
