Inverting an LCD - Page 5 - Toyota Yaris Forums

Here's some "before" shots of my live deck. Keep in mind, I have a WHITE LED modification on this deck.

Here are some "after" shots of my test radio deck. These still have the stock green LEDs.

So the last two are day shots of your inversion? Looks like you have the same problem as me. The night shots look awesome at least. That's really cool with the black on green. Are you going to go for it on your modded deck?

I have no problems whatsoever. Visibility is perfect in daylight.

Awesome!

I take it back. If your viewing angle changes, you will get anything from a grey, to purple, to a rainbow-like display. The display is not consistent, when viewing angle changes.

I might go back to the stock LCD display. Chock this up to experience.

Btw.... I have NO spare film for Sodium Duck. It took me so many attempts to avoid bubbling in the adhesive. I used almost all of what I have.

Did you do anything with the rear film? With the experimentation that I did, if the front and rear film are both flipped, rather than one being rotated, the viewing angle is not affected.

awesome mod idea for any lcd. i didn't think of the radio.

heck, i wonder if my ti-83 will do the trick. lol.

Its strange. On my test deck, the viewing angle is not affected. I did the exact same procedure on my live deck and I have the viewing angle problem. I sliced the film the same direction each time. Perhaps since the decks are different models (6CD model versus 1CD),maybe the LCD displays are different.

I am not sure what films you are mentioning. Front and Rear? There is only one polarizing layer on the LCDs that I have been working with.

Sodium Duck · 03-21-2009, 11:37 AM

LCD's have two polarizers. I think this pic is the right kind to show it.

1. Vertical filter film to polarize the light as it enters.
2. Glass substrate with ITO electrodes. The shapes of these electrodes will determine the dark shapes that will appear when the LCD is turned on. Vertical ridges are etched on the surface so the liquid crystals are in line with the polarized light.
3. Twisted nematic liquid crystals.
4. Glass substrate with common electrode film (ITO) with horizontal ridges to line up with the horizontal filter.
5. Horizontal filter film to block/allow through light.
6. Reflective surface to send light back to viewer.

The radio seems to have only one layer that can be peeled off to affect polarization. On the other side of the LCD, is the side that is exposed in your car, and is a rough texture surface built onto the glass (I think). Again, the weird thing is for me, is that I peeled the same layers off from both decks, cut and applied the new film the same way, but achieve different results.

Meteorite_Marty · 03-21-2009, 11:58 AM

By the way Sodium Duck, I am getting a new 17" sheet from my supplier. Original was actually damaged in shipping, so I was unable to use the entire sheet. The damage had nothing to do with my results. At least I have another chance to offer scraps to you later on.

Sodium Duck · 03-21-2009, 12:20 PM

Cool thanks!

Very disappointing results. Driving without the plastic cover on the gauges, it was fine. But once the plastic cover went on, the visibility went to shit. I even tried doubling up the polarizers, but it went to black. I guess I'll live with it for now. Maybe I'll just splurge on a cluster with tach - only 600 dollars right? lol

Maybe it will be better at night.

WOAH WOAH WOAH WOAH! Are you telling me that I can go get one of these gauge clusters w/ tach and it will tell me my mpg and the gear i'm in and temp and other cool stuff? I have a manual/3dr, does that mean no...? :(

Sodium Duck · 03-21-2009, 03:50 PM

I don't know what the cluster does. It's whatever the S model has on it. There's a ton of threads about it. I'm not even 100% sure it's possible as you'll read in other threads. It's a confusing topic.

hmmm, sounds like a major pain. oh well. lol.

Sodium Duck · 02-21-2010, 04:00 PM

Well, I decided to try and fix my LCD. Up until now, it was just not very visible from my past attempt at this. So I took my last polarizer out to the car and was just playing around with it. Well, if you turn it 45 degrees, you get black on white. Woot. Looks great. I don't know why I didn't think of this before. I took a few pictures to show it. It was hard to get the camera to show what it really looks like.

enobmort42 · 02-21-2010, 06:59 PM

I'd love to do this when it warms up a bit outside. Does anyone know of any retail places that would carry it? I know there's the link, but I hateee waiting for shipping and such lol
