Dark sub-pixel defect - In this image, a dark spot on a white background results from a green sub-pixel, which is in the "off" or dark state.
|
Bright sub-pixel defect - In this image, a bright spot on a black background is caused by sub-pixels (in this case, a red sub-pixel) in the "on" state.
|
|
Debris trapped within the LCD structure can result in dark spots, but under magnification these are distinguished from an "off" sub-pixel, as the shape of the contaminating particle is visible.
