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..

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

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

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

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
02-24-2003, 01:04 PM
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
02-24-2003, 02:48 PM
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.

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.

oh yes, just send it to me and I will fix it up
bailey
02-24-2003, 03:50 PM
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/tools/whitepapers/white_papers/lcd-defective-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%.

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.

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?

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

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?

I still dont get why someone who isnt trying to get it taken back would want to damage their LCD?
If you are trying to kill a pixel so you can take it back to Best Buy, this is legally considered fraud and is unethical at the very least. I don't think we want to go there any more.
I'm not going to censor or close this thread, but let's all think about it, ok?

I clearly stated I do not want to damage my monitor for an Xchange.

but then again you must agree that what you are asking is a bit crazy.
why in the world would anybody in his right mind want to distroy a perfectly good expensive monitor.
you refuse to give any logical explantion for this request.
and you leave yourself open for all weard thoughts as to why you would want to do this thing
1. you are a regestered nut case
2. you want revenge on someone
3. you trying to instagtate some kind of weard discussion here
4. you are a alian looking for a way to distroy the world.
5. refer to one
so as it stands, we have no idea that you have any good intentions.
this post is written in the sense of good humor and nothing personal.
but please give some kind of answer, something that will make sense of all this

bailey,
1- What makes you think it is " perfectly good" and " expensive" as you said? lol
Why I refuse to explain why is kind of personal. I think I have th right to protect some things in my life which i classify as weirdly personal lol.
I have no enemies to take "revenge" on...and wont it be kinda lame to disrupt a few of his 400 million pixels LOL ?
lol @ instagtate a weird discussion..
Simple, I want to disrupt a few pixels on a monitor. Disregard the reason. The intention is anything but "bad".

Hmmm... I've read the whole of this thread and I think I have to agree with Bailey's point one. Either that or you're creating a work of art making some kind of statement on the isolating effect of technology - imagine being one dead pixel in a sea of living breathing pixels :eek:
As to how to do it... I've no idea - what would happen if you stuck a pin into your screen? Probably kill it completely I suppose - tft pixel genocide anyone?
bailey
02-26-2003, 04:52 AM
what if any things have you tried so far, what do you think it would take to kill 1-10 pixals
Force Flow
02-26-2003, 07:55 AM
A high powered, focused laser would do the trick. The only hard part is getting one...
I really doubt that those laser pens are powerful enough. They are definately too large, anyway.
My post was made in an official capacity as a moderator to draw the line as to what is and what is not acceptable to discuss here, not as an accusation. If what I said does not apply, then we have no problem, right? If it does apply, then all I did was do my job.

then why not try what I suggested earler on taking it apart and see how it might be addressed,
I am now thinking that your doing some kind of test to see if it is possible to kill a pixel as a normal consumer, well as far as I know, there is no way possible it can be done, for a pixel to go bad. it would have to be defective in the construction stage of building the matrex, and with the normal vibration from shipping and moveing it around may be enough for the weak connection of the transistor leads to finally break, which would kill one or two pixels.
so from the comsumer stand point, there is nothing that can be done to it that would end up with killing a pixal.

02-27-2003, 12:57 AM
ok:
this will work and no disassembly required,
sence a pixel is basically a photo transistor one thing that will distroy it for sure, a good thump of static electricty, and it would be tiney enough to nail just one, take a small static generator mount a ground plate or even foil over the back side of the monitor, have the hivoltage lead from the source use a needel point type tip, and monitor turned off and disconnected from everything, place the hot probe to the front of the display where the pixel is that you want distroyed, turn on the power of the hi-voltage source just long enough to get one spark jump. wolla pixal distroyed.
by useing a hi-voltage rf type static, no damage will be visable from the screen as the rf will pass through the plastic without any damage.
you would have to improvise the power supply , sence a vandegraff generator may not be readily avaiable,
but you get the idea behind the theroy

aaah what a genius.. I must try this out.. But I need consumer tools.. I got the foil ... what else? :\
BlindFish
02-27-2003, 06:44 AM
Could you generate enough static from the old rubbing a balloon on an acrylic jumper trick... I remember that was one they liked to play on people at school? The spark generated was fairly impressive considering the modest means utilised. Guess it might be a bit more difficult to target it - though usually the spark would jump the shortest distance possible so you could be relatively selective of the area...
Maybe this is a stupid idea?

you will want to try this too,
put on some silk panties, have a dry, low humity rubbersole shoes, thick wool carpting,
just rub your feet on the carpting for a few minutes, then use a needll to tuch the front of the display wher you want to nail the pixel, I can gauntaree that you will generate enough to get at lest two pixels.
have someone take photos of you doing this too, and post them here

ok that was a slip but I have many times seen the transistors in a tv tunner dystroyed by somenoe who got up from their easy chair, walk scross the livingroom to turn the chanel on the tv, as soon as they almost tuched the plastic knob, a good healthy spark would jump to it and bang , no more tv, I open up the tunner and both the rf amp, and the oscillator transistore were shorted, replaceing them restored the tv back to normal, then I was told the story about how it happened.
ps it is a proven fact that women that where silk, do generate a higher level of static charge. a lot faster too .
the panties was just for a laugh.:D

a good way to test if you have the condidions righr is to take a rubber bloon and rub it on the carpet and see it it will rase the hair on your head, ( this is assuming you have any hair left)
if it does then you should be able to do that enough to do the job, if not you have too much humity in the air yet.
