In this study, we present a 260 k-color TFT LCD one-chip driving IC that consumes under 5 mW in the module, which is exceptionally low power consumption. To reduce power consumption, we used many power-lowering schemes in the logic and analog design. A driver IC for driving LCDs has a built-in graphic SRAM. Besides write and read operations, the graphic SRAM has a scan operation that is similar to the read operation of one row-line, which is displayed on one line in an LCD panel. Currently, the embedded graphic memory is implemented by an 8-transistor leaf cell and a 6-transistor leaf cell. We propose an efficient scan method for a 6-transistor embedded graphic memory that is greatly improved over previous methods. The IC is implemented in a 0.18 um process. The 0.18um mixed process is firstly used in world..
