S9 Incell WF Display Description

1. S9: Refers to the Samsung Galaxy S9, a smartphone released in 2018.
2. Incell Display: A type of LCD technology where the touch panel is integrated into the LCD itself, making the display thinner and lighter compared to traditional LCDs with separate touch layers.
3. WF (Waterfall?) Display: "WF" could stand for Waterfall Display, which refers to screens with curved edges that extend beyond the front surface. However, the S9 does not have a true waterfall display, but rather a curved-edge AMOLED screen.

It is likely an Incell LCD version, which is a third-party replacement screen. These Incell LCDs are cheaper alternatives but may not offer the same color accuracy and brightness as the original AMOLED display.
