Solution
LCD stands for Liquid Crystal Display. Each pixel contains three dots of Red, Green and Blue (sub-pixel).
Bright spot: Any regular sub-pixel bright dot under a black screen is always called a bright spot.
Dark spot: Any single sub-pixel that does not light up in a white screen or other non-black screen is called a dark spot.
Defective Standards for LCD Bright/Dark Spots
While checking dark spots on an all-white screen or bright spots on a all-black screen (tip for LCD Pixel Test), check for scratches, dents, and other defects at the same time. If the numbers of the bright/dark dots exceed the number in the following table during the warranty period, then contact Lenovo or your service provider for assistance.
