New Full High Definition 144 Hz AMOLED Driver for Smartphone Displays

OMNIVISION Display Solutions’ OD6631 AMOLED display driver integrated circuit (DDIC) leverages OMNIVISION’s proven image algorithm, high quality and stable supply chain, helping tier-one AMOLED panel manufacturers speed time-to-market. The OD6631 supports higher performance display with much lower power consumption.

OD6631 enables SPR 1280 pixel full high definition (WFHD+) resolution with up to 144 Hz display frame rate for smartphones.

Upgraded from the OD6630, which is in mass production in tier-one AMOLED panel manufacturers, OD6631 is pin-to-pin compatible with the OD6630 and is held to the same high quality standards for customers.
