picture line-up generation equipment (PLUGE)

A PLUGE pattern (Picture Line-Up Generation Equipment) is a test pattern for brightness adjustment of displays

. The Pluge pattern exists in various designs. However, a Pluge pattern always consists of a gray scale with a fixed percentage gradation between the two maximum values white and black

. Using the brightness bars, the brightness curve of the display can be adjusted so that the individual gradations are equal in brightness.

The darkest brightness bar represents black and the black level, the lightest white. If the black or white levels are not set correctly, then the brightness gradations in the black area will be nonlinear, as the gradations closest to black will be too dark and those closest to white will be too bright.
