The Samsung Galaxy Note 8 originally comes with a 6.3-inch Super AMOLED display. However, if you're referring to an In-Cell WF (Waterfall) LCD replacement, here’s a breakdown of the differences:

Original Note 8 Display

• Type: Super AMOLED
• Size: 6.3 inches
• Resolution: 2960 × 1440 (Quad HD+)
• Pixel Density: ~521 PPI
• HDR Support: HDR10
• Curved Edges: Yes (Edge Display)
• Always-On Display: Supported
• Contrast & Colors: Deep blacks, vibrant colors

In-Cell WF (Waterfall) LCD Replacement

• In-Cell LCD Technology: Integrates the touch and display layers, making it thinner than traditional LCDs.
• WF (Waterfall) Design: Mimics the curved edges of the original screen.
• Lower Contrast & Color Accuracy: Blacks appear grayish, and colors are less vibrant than AMOLED.
• No Always-On Display: Since LCDs don’t turn off individual pixels, this feature won't work as well.
• Cheaper Alternative: Often used as a budget-friendly replacement, but with lower display quality.

If you're considering an In-Cell WF replacement, it's more affordable but inferior to the original AMOLED in terms of brightness, contrast, and power efficiency. Let me know if you need recommendations!
