Abstract:
An EL display apparatus according to the present invention includes an EL device adapted to emit light at a luminance corresponding to a current fed thereto. A source driver outputs a current higher than a current corresponding to an analog video signal to the EL device through a source signal line. This operation charges/discharges a parasitic capacitance present in the source signal line. A second gate driver circuit controls a transistor formed between the EL device and the source driver to operate so that the EL device is fed with the current for only a part of a one-frame period. As a result, the El device emits light for only the part of the period.
