Title: Method and circuit for driving optoelectronic panel, optoelectronic panel using the same, and electronic apparatus
Inventor: FUJIKAWA SHINSUKE
IPC: G09G3/20
Filed: 2003-01-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a circuit and a method for driving an optoelectronic panel by which the leak current of a TFT due to a reverse bias of a transistor used for a pixel can be prevented appropriately.  <P>SOLUTION: A liquid crystal device which varies the potential of a scanning line in an unselected state according to the potential of a counter electrode is such that a leading waveform of a pixel electrode potential V2 is based upon the time constant of the counter electrode. A scanning line potential V1 rises from a low potential VSSL to a high potential VSSH with a time Δt behind time T1. This leading waveform is based upon a time constant τG. The time Δt is so determined that the scanning line potential V1 is lower than the pixel electrode potential V2. Therefore, even when the time constant of the counter electrode is larger than that of the scanning line in the unselected state, a leak current due to a reverse bias voltage can be reduced without temporarily turning on respective TFTs connected to the scanning line in the unselected state and the quality of a display image can be improved.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
