Title: Semiconductor device and method for driving the same
Inventor: KIMURA HAJIME
IPC: H05B33/14
Filed: 2004-02-23
Abstract: A semiconductor device wherein the write operation of a signal current can be performed quickly in a current input type of pixels. A large current is caused to flow, thereby performing a pre-charge operation prior to inputting a signal current. Thereafter, the signal current is inputted to perform a set operation. Since the pre- charge operation has been performed prior to the set operation, a predetermined potential can be reached quickly. This predetermined potential is approximately equal to a potential obtained at a completion of the set operation. Therefore, the set operation can be performed quickly, so that the write operation of the signal current can be performed quickly. It should be noted that the use of two transistors increases the gate width (W) or reduces the gate length (L) during the pre-charge operation, while reducing the gate width (W) or increasing the gate length (L) during the set operation.
