JScreenFix – Repair stuck pixels

<p><pre><code> .</code></pre>

What a clever idea! My very first thought was &quot;bullshit!&quot; when I saw the title on HN but after my actual brain had a real chance to think about it I immediately reversed course.<p>It&#x27;s cool to think that an interpreted language running in a browser can actually fix hardware, for a certain definition of fix.

Has anyone actually repaired their screen with it? For me, it just didn&#x27;t work; after four hours or so, I simply gave up. (Sony LCD screen, really high-quality, a few stuck pixels in a specific area)

I&#x27;d like to see some evidence for that &quot;&gt;60% success rate&quot;. Programs that do this have been around for a <i>long</i> time (e.g. <a href="http:&#x2F;&#x2F;udpix.free.fr&#x2F;index.php?p=about" rel="nofollow">http:&#x2F;&#x2F;udpix.free.fr&#x2F;index.php?p=about</a> ), and having talked to some people who have tried them in their repair shops on customer&#x27;s monitors overnight, it&#x27;s more likely that pixels which were stuck in the first place are either truly stuck, or intermittent ones that come and go due to minor fluctuations in pressure and heat, and that those claiming to have theirs &quot;fixed&quot; by this program might just be because they left their monitor on long enough that the small temperature increase induced by the cycling was enough to close an intermittent connection.<p>Those that can truly be fixed with slight pressure&#x2F;&quot;massaging&quot; can also be similar - intermittent electrical faults - or foreign matter&#x2F;voids in the liquid crystal itself.

I had a stuck pixel on this very Nexus 7. It stayed red for a few days as I played some 24hr YouTube vids that used the exact same principle. After ~2 days, no wonky pixel. Honestly, I think it was temp fluctuation, but whatever... it is fixed. :)<p>I have no stuck pixels currently and I try to forget the whole experience as I might have almost junked the N7 because of my annonying Jr-OCD.

having used these type of programs for years, I like that your allows targeting a specific screen area rather than full-screen snow. Keeps the headaches down. Thanks.

That&#x27;s a great way to keep people &#x27;looking&#x27; at ads for 10+ minutes.<p>And if it works, cool. I never had a dead pixel as far as I remember.

The pixels in the image don&#x27;t seem to be the same size as the pixels in my retina display, would this influence the results?

How do pixels become &quot;stuck&quot; in the first place? What is the mechanism by which this happens, and how does this technique fix it?
