SIGNAL LINE DRIVE CIRCUIT, LIGHT EMITTING DEVICE, AND ITS DRIVE METHOD

摘要

A transistor generates a dispersion in characteristics. This signal line drive circuit has current source circuits and shift registers corresponding to the respective wirings. Each of the current source circuits is characterized by having a capacitor means which converts a supplied current into a voltage according to a sampling pulse to be supplied from the shift register and a supply means which supplies a current corresponding to the converted voltage.
