ST7703
1. General Description
The ST7703 is a single-chip solution for a-Si TFT LCD that combines a source driver,
power supply circuit to drive a-Si TFT dot matrix LCD with 720RGBx1280 dots at
maximum. The ST7703 supports MIPI Interface.
The ST7703 incorporates step-up and voltage follower circuits to generate drive
voltage required for a-Si TFT and gate in panel (GIP) which including a dynamic
backlight control function to control backlight brightness depending on image data,
reducing power consumption at the backlight with the slightest influence on image
quality.
The ST7703 is suitable for small or medium-sized portable mobile solutions requiring
long-term driving capabilities, such as digital mobile phones, PDAs and
Smartphones.
