3m upgrades - Page 14

did you even go to the 3m website?

go to the website and look at the specs for each one. Also you should have gotten the ESR aswell

Where else would I have gotten the samples? like I said, what would the best combination of the screens that I have be? thanks.

I've received a

BEF II 90/24
BEF II 90/50
BEF III 10T
My screen is a Lilliput K301
here's a pic
In the pics is my old carputer
My new carputer (running knoppix until my new harddrive gets in)
Screen
Picture of My car
and 3M films

All of those are very similar and made to do basically the same thing. I'm not sure your supposed to stack more than 2 of the BEF's, so you're better off just cutting 2 piece in opposite directions from the same sheet. I don't know if different BEF's should be mixed and matched either.

the samples you should have gotten instead of all the same type are:

BEFII
DBEF
ESR

BEFIII is less effective than BEFII, it was just created as a thinner alternative however due to being thinner it loses it's effectiveness when compared to BEFII.

If after applying the BEFII 90/50 you experience Moire, you should try to switch to BEFII 90/24 as it is intended to reduce Moire.

take apart the backlight and apply the ESR film EVERYWHERE that light can reflect from.

Remove the stock films including Diffuser film.

Cut 2 BEFII pieces in opposite directions and apply those directly on top of the Backlight.

Cut a piece of the DBEF and apply this on top of the BEFII sheets.

LCD goes on last.

The ESR has >98% reflectivity across the light spectrum, this should reflect ANY and all light that makes it through the LCD and to the backlight increasing the brightness further.

The BEFII reflects the P2 light back to the ESR reflector in the form of P2 and P1. P1 passes through the BEFII.

DBEF is a reflective polarizer.

This is all information on 3M's website and should also be included in the literature they sent with the films. (you probably don't have the ESR and DBEF info included since you didn't order any)

I took the plunge and did my new Liliput EBY701 - Two sheets of BEFII with the second rotated 90 degrees, then a sheet of DBEF 0 Degree on the top of them.
Now I hadn't used this screen much anyway since its pretty new, but it doesn't seem any brighter to me. The viewing angle does appear to be greatly increased though.
I'm yet to test it out in sunlight as I'm in the process of finishing off my new install so it will be interesting to see how readable it really is.

Just as a note, this screen didn't appear to be 'pre-fitted' with any type of film when I took it apart.

Edit - I've just noticed in nst6563's post that I was supposed to remove the 'diffuser film' - I didn't take any film out as there didn't appear to be anything 'loose' between the lcd and the backlight (although I didn't strip the backlight fully) is there any point in me going back in to search for the diffuser or will it not make much difference ?

antimatter · 09-13-2007, 04:06 PM

I think it is safe to say that the LCD should perform similarly (pre modification) indoors. Once outdoors you should notice a difference when in direct sunlight. If you dont then perhaps you have the films installed the wrong way

As far as the diffuser. if it looks fine with it off then leave it out. If you can take the monitor outside hooked up to a laptop or soimething and take some pictures of it in direct sunlight. I hope you got the results you wanted.

The EBY701 is the first one I did the upgrade to as well. It didn't make that much of a difference inside, but a huge difference outside in the sun thats for sure. There were no films whatsoever in that unit from the factory.

I still have BEFII 90/50 film available for anyone looking to do theirs:

You can use a single sheet, cut in half, to get your 2 layers.

swift_gti · 09-13-2007, 04:16 PM

Thanks Sam.. good to know that I hopefully haven't just wasted my time

Can I ask, did you remove anything from the screen when you installed the films (the diffuser for example ?) I couldn't see anything in there that could easily be removed.

I will try and get some pics up, but it may be some time as I'm having problems with my amp, and I'm still fabricating my moulding for the dash...

antimatter · 09-13-2007, 04:21 PM

I'd be interested in getting a hold of some of the antiglare coating if any one has a large enought peice for the 7" and isn't using it

hey guys sorry it too me so long to get some pics up. These pics really dont do the screen justice, because it looks much better in person. One thing you can see here is how the touch panel picks up reflections.

nst6563 · 09-13-2007, 09:04 PM

I also have the Eby-701 and there are films in it from the factory. There are 2-3 actually. A diffuser, a prism similar to BEFII, and I believe a polarizer.

I'll have to take a picture when I do my other screen this weekend, but I'll try to explain it best I can.

When you lift the LCD from the backlight, there is that thin metal frame around the backlight. You remove this frame, which is what is holding the factory films down. They are keyed and not just straight square pieces, which is why they aren't very loose. They are hard to tell at first because they are fairly transparent against the white background of the diffuser, but I found them after taking that metal frame off to install the ESR film in the backlight.

actually...found some pics already up here. Check out post #106
http://www.mp3car.com/vbulletin/lcd-...pgrades-8.html

scroll through the pictures and there is shown the pre-installed films. Starting with the 8th photo you can see what the metal frame is I'm talking about, and a few pics below that you'll see the films and diffuser.

In the 3M literature that was sent with my samples, they mention that the diffuser is optional when used with the BEFII films. I took mine out as I installed the ESR into the backlight, 2 sheets of BEFII at 90 degrees of each other, and DBEF-0. The diffuser MAY actually be a good sheet to put OVER the touchscreen as it is clear when up against the LCD, but shows very little glare and almost no reflection when I shined my spotlight on it at varying angles (1million candlepower - figured that'd be a decent substitute for the sun in my garage)

anyway, when I do my install this weekend on my second screen, I'll take some pictures of it, maybe it will help some other's in this quest as it seems that not a lot of people ordered the ESR which I think may help a lot in the sunlight.

swift_gti · 09-14-2007, 02:48 AM

Interesting stuff... I will take mine apart again and have a look.

I didn't remove the metal frame hence why I didn't notice the films underneath.

NST6563; Does your EBY-701 look any brighter at all (indoors) after you put the films in?

Like most others I didn't order any ESR

Will it make THAT much of a difference to the screen not having installed it ?

nst6563 · 09-14-2007, 07:35 AM

yep, all those films are held in place by that metal frame...sneeky of them.

But I think the ESR film *may* make a big difference when outside as it will reflect >98% of the light that comes in. I'll definately find out this weekend when I put it in the screen in my car.

As for a difference indoors, not much really. There was a difference in brightness but it was hard to catch on camera and the difference wasn't 'huge'... didn't seem like the claimed "up to 120%" that 3M claimed when using to sheets of BEFII at 90 degrees. I hadn't taken it outside much as I don't have a video source outside unless I take the car apart and hook it up there, but with the garage door open and the sun coming in, it was quite readable with brighter ambient light conditions. I could also see it just fine when shining my 1million candlepower spotlight directly at it.

I'll definately take some pictures of the in-car setup to show the difference though... thank god it's Friday too... can't wait

changeip · 09-14-2007, 11:47 AM

The pictures in the walk thru in post 106 are not the same as my EBY-701 ... isnt that a 619? The LCd panel and backlight looks similiar but the electronics and connectors are different. There must be a few variations of this same unit as well. I will get more pics of mine this weekend when I swap it out for my Xenarc.

antimatter · 09-14-2007, 11:56 AM

Thanks for posting the pics. It does look good and bright. I'd like to see it with the sun beating directly on it though.

I just requested some samples. I think i have a good chance of getting them. I was wondering for those who recieved samples how long did it take from when you first emailed to recieve the samples

Now all we need is some sort of antiglare treatment for the touchscreens. I have to say that i think it is so freekin lame that the MP3car wont sell the clearer polorized touchscreens. Argg
