A 3.5-in. QVGA-formatted driving-circuit fully integrated LCD has been developed using low-temperature poly-Si (LTPS) technology. This display module, in which no external ICs are required, integrates all the driving circuits for a six-bit RGB digital interface with an LTPS device called a "FASt LDD TFT" and achieves a high-quality image, narrow frame width, and low power consumption. The LTPS process, device, and circuit technologies developed for system-on-glass LCD discussed. The development phase of LTPS circuit integration for system-on-glass LCDs is also reviewed.
