Title:
ORGANIC EL PIXEL CIRCUIT
Document Type and Number:
Japanese Patent JP2002244617
Kind Code:
A
Abstract:
To prevent an afterimage from being caused in organic EL elements.
The organic EL pixel circuit is provided with a discharge transistor TFT3 for connecting the upper end of an organic EL element EL with a negative power source VEE, and a control transistor TFT4 for connecting the upper end of a storage capacitor SC with a power source PVDD. By switching on these TFT3, 4 by the gate line of the prestage, the capacitance of the organic EL element EL is discharged before own line is selected.
