P-33: A Novel TFT-LCD Characterization Method Using Retention Measurement

Osamu Tokuhiro; Katsuyiki Furumoto; Mikinari Sorida; Yoshihiro Miyazaki

We have developed an optical measurement system for TFT-LCD cells which measures not only conventional optical characteristics such as voltage-transmittance, flicker and response time but also retention time. By using specific TFT driving condition, retention time measurement can address the cause of various current leakage problems.
