moving Grid Screen graticule/LCD recycle

[catman72]

hi there,

you seem to know a lot about LCD screens structure, maybe you can help me.

i'm looking for a way to remove the polarizing filter off the screen, and keep the filter undamaged. the glass is of no interest for me, just the filter.

i tried acetone, hot water, and several solvents, but no go.

any idea?

i remember in high school -i used to flip the polarised screen over in my calculators so that the screen was black with white digits-maybe pull apart cheap monotone LCD's-what do you want it for?

interesting effect, if you have two such grids with tiny hexagons instead of the squares as you have, when you slide them you will see large hexagons! and if you have a grid of evenly spaced dots, or circles, , when you slide the two grids, you will see large dots or circles, whatever the shape of the tiny grid , when you put two together and slide them, you will see the same shape as you have seen here with the squares.... very cool,

thanx for commenting - i ahve always been fascinated by intereference patterns

Huh, I can't hear you.

That is AWESOME! how you used that old camera lins and Zoomed in with your Digital Camera like that.But what was that you where looking at??? I could not hear what you where saying very good, sorry. I think I will buy one of those old lins if I find one and try that. Thanks john...

yeah any lens will work for close up work (even an magnifying glass)-im having issues with a new camera and the high sound gain.

hears way too much background ,as a result makes the voice the mud in the middle.

think i got it sorted tho -i cut up an ear plug and stuck it over the microphone hole.

we will see when i post next.

the thing i was looking at is a sliding scale graticule,which can be calibrated and used at the focal point of optical devices.

basically a high tech measuring stick

lenz? solar maybe??

ps. im not sendin me lappy to you to get the screen fixed, haha

[m3sca1]

solar!-yup you guessed it.

thats why i started mauling the LCD screen.

go on sned me your lappie and i will return it as a solar panel!

[harpbloke]

ha, dude, your a nut ! the kind we all like. fair play to ya, and fab to here the accent,, makes a we bit home sick. keep up the good work lad ! well done

interesting. food for thought. yet again you have got my brain pumping. I can see several other uses for this as well. depending on the accuracy of the grid it may be possiable to use it for cnc machines for feedback. perhaps on a different scale. and the fact that it is basicly a sealed unit it would keep coolant and debri from damaging the scale. i can easily build a laser iterferometer to do the measruing for the device. keep me posted will ya.

thanks

now thats why i do, what i do.

to supply brain food.

thats a great idea-the graticule is vey fine,and its accuracy as a grid would be high,due the close spacing of the pixels.

you can see how fine it when i have the big lens on it.

[neotoy]

cool.

[m3sca1]

thanx for commenting

this isnt the reason i pulled down the LCD screen,but i thought it was cool too...more to come.

cant wait

very cool i watched this before but didnt catch the grid thing i couldnt see it but it seems more clear now very nice that would totaly make a good range finder say you had it on a tri pod wit ha site

tube you could surround a person in a cube and consult a chart to determan range you would halve to make the chart though not so easy but im glad i watched this you could tell if a dear was to far away or a cop car if you had to shoot

a crooked cop we got a 99% crooked cop ratio here no sht bro
