How to see if the screen is a dead pixel or dust

Upload a pure white and a pure black ** to the tested mobile phone, look at the screen, if the brightness is uneven, it is a bad pixel.

Otherwise, it's dust.

Just open an all-black ** and look at it If it's gray, you can see it very clearly under the sun If it's a bright spot, you can use an all-black ** to see it in a dark place If you see a bright spot, it's a bright spot on the screen, and if you see a blue or red or green one, that's a bad pixel.

Dim the screen and you'll be able to see it at a glance, hopefully.

Even if it's a dead pixel or bright spot, screenshots can't be taken ......And the software can't detect dead pixels on the screen, all screen inspection software uses monochrome images to display on the screen, which then needs to be recognized by the naked eye. However, if you use it normally, it will not produce dead pixels, and I think it may be the dust on the film.

In fact, there is another way, which is to use a magnifying glass with a slightly larger magnification to look carefully. If it's a dead pixel, the shape should be the same as the normal pixel next to it, but if it's dust or other debris, the position, shape, and edges are completely different from the next one, so it's easy to see.

Screen dead pixel refers to the damage of LCD pixels, the shape should be the same as normal pixels (generally square, the edge is intact), if it is smaller than the normal pixels, it is not a bad pixel, it may be impurities on the film.

Dust is dull, dead pixels are shiny.

3.If you can't see clearly, you might as well use a magnifying glass to see if the black spot is far away from **, if so, it is dust. 4.

The software can test the black spots, you can use the software, and the software analysis will tell you the results.
