Proximity of Pixel Defects

A red or blue bright dot must be more than 50

Because pixel and sub pixels defects of the

neighboring dots.

for the proximity of pixel defects.

Black Dot Defects

 

 

 

 

 

Black dot defects appear as pixels or sub pixels

 

 

 

 

 

that are always dark or 'off'.That is, a dark dot is

 

 

 

 

 

a sub-pixel that stands out on the screen when

 

 

 

 

 

 

 

 

 

 

the monitor displays a light pattern.These are

 

 

 

 

 

the types of black dot defects.
