When running Defpix, you are searching for three distinct types of pixel anomalies:
Stuck Pixels: Sub-pixels that remain permanently on, causing a bright red, green, or blue dot regardless of the background color.
Dead Pixels: Transistors that have completely failed and remain permanently turned off, showing up as a solid black dot.
Hot Pixels: Defective pixels that stay purely white because the color filtration layer has failed to block the backlight. How to Use Defpix Effectively Touchscreen Dead pixels Repair – Apps on Google Play
