36.1: 6-Bit Digital VGA OLED

Mayumi Mizukami; Kazutaka Inukai; Hirokazu Yamagata; Toshimitsu Konuma; Takeshi Nishi; Jun Koyama; Shumpei Yamazaki; Tetsuo Tsutsui

We developed 0.7 inch VGA TFT-OLED with a 64 gray-scale integrated driver circuit. The TFT-OLED has good image uniformity due to digital operation. Control in a time-ratio was useful for achieving large gray-scale level. Our simplified pixel configuration accomplished high resolution.

36.4L: Late‐News Paper: 4.0‐in. TFT‐OLED Displays and a Novel Digital Driving Method

Kazutaka Inukai; Hajime Kimura; Mayumi Mizukami; Junya Maruyama; Satoshi Murakami; Jun Koyama; Toshimitsu Konuma; Shumpei Yamazaki

We propose a novel type of digital driving manner of TFT-OLED display by time-ratio gray-scale (TRG) expression. The advantage of this is remarkable especially in large, color, or high-resolution TFT-OLED displays. A 4.0-in. TFT-OLED monochrome display employing this sophisticated digital driving method is demonstrated.
