21.3: Invited Paper: Latest Development of “System‐on‐Glass” Display with Low Temperature Poly‐Si TFT

A 2.3-inch diagonal, QVGA formatted “System-on-glass” display has been developed by low temperature poly-Si TFT LCD technology. This display fully integrates 6-bit RGB digital interface drivers as well as all the power-supply circuitry to drive the LCD, which requires neither external ICs nor power supply ICs. This paper discusses the newly developed TFT circuit technologies used in this LCD. The development trend in the “System-on-glass” display is also reviewed.

Latest developments for system-on-glass displays using low-temperature poly-Si TFTs

A 2.3-in.-diagonal QVGA-formatted System-On-Glass display has been developed by using low-temperature poly-Si TFT-LCD technology. This display fully integrates 6-bit RGB digital interface drivers as well as all the power supply circuitry to drive the LCD, which requires neither external driver ICs nor power-supply ICs. This paper discusses the newly developed TFT circuit technologies used in this LCD. The development trend of the System-On-Glass display is also reviewed.

L‐2: Late‐News Paper: A 2.2‐inch, Narrow Frame Liquid Crystal System Display with Low Voltage Interface Circuitry

A 2.2-inch, QVGA format system display, which fully integrates a low voltage 6-bit RGB parallel interface circuit, has been developed by using low temperature poly-Si (LTPS) TFT technology. This panel integrates a low voltage (1.8V) interface circuit, which directly connects to an external controller LSI. We also have developed a horizontal driver that allows for the narrowest frame width to date in mobile displays.
