Want to De-Pixel my LCD

[CorruptedSanitY]

I want to know if there is any way I can make a pixel die.. or cause or disable a pizel..kill a pixel on my LCD.. Basically I want a dead pixel on my LCD monitor.

thanks..

[bailey]

if I recall correctly, they will not warranty it with just one dead pixel, you must have at least 10 ot more.

just out of couristy, why would want to ruin your monitor

[Spyda]

maybe he has a pixel error where its a white dot and he wants to kill the white pixel.

[bailey]

I don't think there is a way one could do that.

[CorruptedSanitY]

i just need to kill one out of the millions of pixels.

[Spyda]

i know what you mean, but if this is your problem, the pixel that is bright white is already dead, and there is no way around it, the bright white is the backlight

[CorruptedSanitY]

I didnt say I had any one pixels.. I just want to kill any random pixel on my 18.1" monitoe

[bailey]

may I ask why ???

[CorruptedSanitY]

guys.. i dont wanna sound rude..but for some reasons i cannot say why.

Just really need y'alls help

[abliaya]

Maybe he's gonna mess with his wife's monitor or something like that!

[bailey]

I am sure that there is a way to do it but never looked at it from that point of view, kinda burning a spot in the center of a crt.
but it would take a lot of work to do this, to me not worth thinking about

[CorruptedSanitY]

abliaya...
1- im not married :P
2- why would i mess with my wife's monitor assuming i was married LOOL

bailey.. i need to do it lol

[Force Flow]

Short of hitting it, overheating it with a heated needle, poking it hard or dropping it, I can't really think of a way to do this.

You might be able to ask a monitor repair person.

[bailey]

do you understand just how that display works,
it is a array of millions of transistors in a grid kinda like ram is,
you would have to find a way to address one of them, then apply a distructive voltage to it hoping that would distroy that one pixel and not tuch any of the other ones next to it, any attempt to do this more than likely would distroy the entire display, not a good thing to try

[CorruptedSanitY]

force_flow's method seems more fun LOL and more effective.

bailey's method is more scientific and will prbably producde better results if done right

I am still open to suggestions.


I will not be greedy. I would not mind 10 dead pixels.

[bailey]

depending what type of dislpay it was would have to be known first, a ttf display would be confiqured differantly than a passive one. the pasave type you may be able to distroy the liquid cristal or one of the filters by striking it with something small tiped and a light hammer, the ttf would have to be addressed and spiked directlyyou could even take a very small drill bit and drill out the cristal or transistorsence there are 4 million just take your pick.

[CorruptedSanitY]

well bailey..this is what is needed to be de-pixeled




any suggestions?

[bailey]

oh yes, just send it to me and I will fix it up

[bailey]

ok by apperance, I would guss that it is a ttf type display, I have never opened one up, but each transistor must be controled, sot I first would open it up and look for any traces that would indicate the addressing matrex, and pick a connector of some type at the two ends,( vert and horiz ) and just spike a small voltage across it, that should destroy something, hopefuly it would be addressed as I am thinking and kill the addressed junction, mind you I am just guessing off the top of my head, and doing so at your own risk of destroying the whole thing

If you do that, then you'd probably poke through the plastic coating; aka: not good.

Here; this may help: http://www.infinitytech.com/website2...ive-pixels.pdf

Active matrix TFT LCD panels achieve their beautiful images, in part, because of the individual transistor placed at each pixel which controls the backlight shining through a given pixel (see Figure 1). Occasionally, these individual transistors will short, or otherwise malfunction, resulting in a defective pixel. There are two phenomenon which define a defective LCD pixel: A "lit" pixel, which appears as one or several randomly-placed red, blue and/or green pixel elements on an all-black background; or a "missing" or "dead" pixel, which appears as a black dot on all-white backgrounds. (By comparison, CRT defective pixels exhibit themselves as black holes in an all white raster. This is due missing phosphor material or an obstruction in the shadow mask.) The "lit" pixel phenomenon, more common than "missing / dead" pixels, results when a transistor occasionally shorts on and results in a permanently "turned-on" (red, green or blue) pixel. There are some possible corrective measures, such as "killing" a transistor using a laser, however, this just creates black dots which would appear on a white background. Fixing the transistor itself is not possible after assembly. Additionally, it is not possible to turn a "lit" pixel off, except for the aforementioned laser method, which essentially just makes the transistor in-operational, thus resulting in a black dot. Turned on or "lit" pixels are a fairly common occurrence in LCD manufacturing. Like their CRT counterparts, LCD manufacturers have set limits as to how many defective pixels are acceptable for a given LCD panel, based on user feedback and manufacturing cost data. The goal in setting these limits is to maintain reasonable product pricing while minimizing distraction from defective pixels for maximum user comfort. Considering the number of pixels contained in a LCD panel, this defective rate is quite minute. For example, a panel with a native resolution of 1024x768 pixels contains a total of 2,359,296 red, green and blue pixels per panel (1024 x 768x3 = 2,359,296). Therefore, a panel with 20 lit pixels would have a pixel defect rate of: (20/2,359,296)*100 = 0.0008%.

[bailey]

that would do it, fire a laser beam at it and it will do just what you want, thats the perfect answere to your question.

[Trent Steel]

Reading this thread I am quite interested in why you would want to de-pixel your monitor. The only assumption that can come up with is that you have one or two dead pixels and cannot return it under warrenty as you need a minimum of three dead pixels.

[CorruptedSanitY]

haha nice accusations so far..

1- I wanna distroy my supposed wife's monitor LOL

2- wanna eXchange it for a new one..

f.y.i guys.. I have bestBuy waranty which will compleltey Xchange it if 1 dead pixel shows up..just ONE..

its soemthing else.. i may be able to tell u all after im done killing one or two pixels.. plz dont think im BS'ing y'all.. coz i have better things to do with my time than BS u guys..

believe me..the means defines the end..

[Force Flow]

I think the phrase is "the end justifies the means," but whatever.

Just curious, where would you get a laser powerful enough to kill off these pixels?

[CorruptedSanitY]

so u guys are saying..get a laser pointer or laser beam at it?

are you guys sure? o_O

do y'all mean something like this?

[Force Flow]

I don't think the beam would be tight enough. I have one of those lasers and the spead is pretty wide for trying to kill off just a pixel or too. I have no idea whether or not if it'll be powerful enough, either.

Nice set-up, by the way. Is it in place of those small, flat batteries?

[CorruptedSanitY]

ahahaha they aint my setup man.. i thought it was obvious i was linkin from some image i found on images.google.com

although i could do that.. its not tough..

[bailey]

just look at thes hands, he never did a hard days work in his life, no callious, blisters cuts scars or even missing fingers

I though it was posted a little to fast to be a digital photo...

Hmm... that my actually be a possibility.
