18.2: A 2.15 inch QCIF Reflective Color TFT‐LCD with Digital memory on Glass (DMOG)

We have developed a 2.15 inch diagonal, QCIF(144×RGB×176) reflective color TFT-LCD with a new integration technology called DMOG (digital memory on glass), using low-temperature polysilicon (poly-Si) technology. This panel is able to display 4bit × RGB (4096-colors) images and 1bit × RGB (8-colors) still image in power save mode (still mode). We have achieved low power consumption up to 1.3mW in still mode using DMOG.

28.1: Distinguished Paper: A Novel Low-Power-Consumption All-Digital System-On-Glass Display with Serial Interface

We have developed a low-power LCD panel with a serial interface by combining the technique of integration of serial data receiver function and pixel memory circuits. It has achieved a low power consumption of 15uW in a 2.26-inch format.

A novel low-power-consumption all-digital system-on-glass display with serial interface

— A new conceptual ultra-compact LCD panel, which features a simple interface and lower-power consumption by using low-temperature polysilicon thin-film transistor (LTPS-TFT) technology has been developed. This panel is capable of switching operation modes based on an input command, and all the data are directly communicated with the circuit inside the panel through a Serial Peripheral Interface (SPI) protocol. The integration of the serial-data-receiver function on glass substrate has enabled the achievement of a significant reduction in the number of interface pins. Moreover, a low power consumption of 15 μW for a 2.26-in. reflective LCD panel in combination with the technique of integrating a memory circuit in each pixel has been achieved.

28.2: 3.5 Inch VGA TFT LCD with System‐On‐Glass Technology for Automotive Applications

We have developed a 3.5 inch VGA TFT LCD with Capacitively Coupled Dot Inversion (CCDI) driving for automotive applications using System-on-Glass Technology (SOG). A drastic reduction in the number of connecting points (one-tenth), low power consumption and high display quality have been achieved compared with conventional a-Si TFT LCDs.

18.4: Novel Gamma Correction Method Using an Advanced Capacitive Coupling Driving

We have developed a LCD panel for mobile-use applications that adjusting each RGB gamma characteristics independently without increasing the scale of peripheral circuit. It has been realized by using the Capacitive Coupling driving method and optimizing the storage capacitances of R, G, and B subpixels independently.
