On July 17, Seiko Epson Corporation announced the successful development of a new controller chip series, designated S1D19501, designed for 176×220 pixel TFT LCD screens—a common type of display used in mobile phones.
The company has also begun shipping samples of these chip designs.
The S1D19501 is a single-chip controller that manages Si-TFT LCD screens, integrating display data memory and capable of displaying 262,000 colors.

By embedding a 220 pixel output port controller and a 176 pixel output power controller (RGB) along with the power circuits for the display onto a single chip, it is now possible for one chip to drive a TFT color display module with a maximum resolution of 176 RGB x 220 pixels.
The S1D19501, a single-chip TFT controller capable of displaying high-resolution images, utilizes a 0.13µm manufacturing process. It represents the third generation of Epson’s chip series, succeeding the S1D19105, which was produced using a 0.25µm process, and the S1D19121, which utilized a 0.18µm process.
Furthermore, thanks to the application of ultra-thin technology in the 0.13µm manufacturing process, the thickness of the chip has been reduced to approximately 1mm, which is about 34% thinner compared to conventional products.
