ABSTRACT:
Embodiments of an organic electroluminescence display capable of preventing line mura generated due to manufacturing differences in driving transistors are disclosed. The manufacturing differences may be due to deviations of irradiated energy beam density generated from an excimer laser annealing process for crystallizing amorphous silicon into polycrystalline silicon. One embodiment of an organic electroluminescence display a plurality of pixel circuits arranged perpendicular to a laser scan direction for crystallization. Each pixel circuit comprises an organic light-emitting diode, and a driving transistor configured to supply current to the organic light-emitting diode. Each driving transistor comprises at least two channels formed therein, wherein the sums of lengths of the at least two channels in each driving transistor of the display are equal.
