Screen & Lighten - What's the Difference?

Hi guys,

Under Blending Options > Gradient Overlay > Blend Mode, there's an option of Screen and Lighten. May i know the difference? I can't tell the difference when applied.

Thanks a bunch!

Screen Looks at each channel’s color information and multiplies the inverse of the blend and base colors. The result color is always a lighter color. Screening with black leaves the color unchanged. Screening with white produces white. The effect is similar to projecting multiple photographic slides on top of each other.

Lighten Looks at the color information in each channel and selects the base or blend color—whichever is lighter—as the result color. Pixels darker than the blend color are replaced, and pixels lighter than the blend color do not change.
