Seiko Epson launches an ultra-thin color TFT display control chip

On July 17, Seiko Epson Group announced the successful development of a new line of control ICs with S1D19501 numbers for 176x220 pixel TFT LCD screens - a universal screen for mobile phones.

The company has also begun shipping these IC designs.

S1D19501 is a single chip microcontroller line that is responsible for controlling unformatted Si-TFT LCD monitors integrated with display data memory and is capable of displaying 262,000 colors.

By embedding a 220-pixel output control circuit and a 176-pixel (RGB) output control circuit along with the power supply circuit for the monitor on the same chip, a single chip now has the ability to display one Color TFT screen module with a maximum of 176 RGB x 220 pixels.

As a single-chip TFT control circuit with high resolution image display capability, the S1D19501 series with 0.13µm production process is the third generation product of Epson serial series S1D19105 manufactured according to the process. 0.25µm and S1D19121 series with 0.18 µm manufacturing process.

Moreover, thanks to the application of ultra-thin technology of 0.13 µm production process, the thickness of the chip has been reduced to approximately 1mm, which is about 34% compared to conventional products.
