In this study, we present a 260k color VGA TFT one-chip LCD driver IC that consumes low power in module. To reduce power consumption and a chip size, we used a sub-pixel rendering and a data compression algorithm. The currently, in order to display the bigger and higher resolution, the imbedded graphic SRAM size becomes bigger. But, because the mass-production size has limitation, the driver IC of a VGA resolution is normally two or three chip solution. The study is the first time made VGA one-chip IC in world. The IC is implemented in a 0.15 mum process.
