Inverting an LCD - Page 2 - Toyota Yaris Forums

Correct. The LCDs I inverted had a metal frame around them, so I was able to simply sandwich the ES film. If you go with a non-adhesive film and find that the LCD doesn't have a frame, you can simply tape the film around the edges, making sure that the tape doesn't extend past the frame coverage.

Much to contemplate now. haha

My gas gauge is already inverted, from factory. Black background with white text.

I want to do my radio to match it. I have already done a white LED replacement on my radio (replaced the green LEDs). Currently the radio has a white background with black text, but would like the display to inverted. This way it would match my dashboard displays.

Which one did you order? Functionalitywise, are they all the same? It looks like they just differ by size and anti-glare.

I'm just going to go with the Edmund Optics, but I'm not ordering until I go out and pop my gauge cluster out. I want exact measurements of the LCD before I go ordering something.

Like Scott said, some tape will hold it in place fine. I may even do a dab of some silicone adhesive in the corners for a more permanent thing.

Can you post pics of your dash? Are you talking about the black background and green horozontal gas gauge thing? Or I've seen another one that had more of a blue-ish background.

Meteorite_Marty · 03-10-2009, 06:04 PM

Here are the pictures of my dash.

Sodium Duck · 03-10-2009, 06:24 PM

Ahh yes, it has that blue-ish background.

I think you'll just have to buy an extra big sheet from Edmunds to cover it all.

Tommorow I'm going to pop my gauge cluster out, take measurements, and order from Edmunds. If I end up needing a bigger sheet, I'll sell the leftovers for cheap.

Some of the ones there are not indicated for use by LCD screens. There are only a few listed that are intended for LCD's. Aside from that, they are based in Taiwain, and I don't like dealing over the seas.

Well, I am happy with the dashboard. Its not as "blue" as it looks. Blends nicely into the dark for night driving.

I am going to try and do this for my radio display, to unify the look.

Sodium Duck · 03-11-2009, 12:50 PM

So it looks like the visible area is about 1 7/8" X 3/4" and the actual LCD itself is about 2" X 1".

Hmm. I'm going to think about it for a couple hours then decide which film to buy. If I get the one from Edmunds, I could simply put the 2" X 2" sheet down and tape/glue the overhang above and below to the plastic case. Then the black face for the gauges would hold the rest down sufficiently I think.

Sodium Duck · 03-11-2009, 12:51 PM

Forgot to add pics... boink.

Snap some pics of the PCB with the microcontroller, etc. PK's been anxious for someone to post some when they have their combo meter assembly apart...

Sodium Duck · 03-11-2009, 01:16 PM

... I just got back from putting it back in my car ... Dang!

When I take it apart again to do the film I'll take more pics. To be honest though, I think I'm going to do this mod without taking much apart. All you have to do to gain access to the LCD is pop the front plastic off the gauge cluster, pull the speedo needle (which I was too sissy to pull hard enough on to actually remove for these pics), and take the background off. The LCD is just sitting there. It snaps into place with those four little white indented tabs you see in the pics. Then there are 22 really long pins on the bottom of the LCD that go down to some connector.

Does he want pics of the whole circuit board taken apart, like the people who did the LED color changes to their gauge cluster?

Sodium Duck · 03-11-2009, 02:08 PM

Good gravy.

NT43-781: $8.00
Subtotal: $8.00
Tax: $0.40
Shipping: $9.32
Total: $17.72

9 bucks to ship me a 2" X 2" piece of paper... I'm going to search around the net and see what else I can find. Even the stuff from Taiwan was only 4 bucks to ship, but they have a minimum $10 purchase thing. Still, it'd only be 14 bucks.

Sodium Duck · 03-11-2009, 04:13 PM

Sounds cool. I'd like to have temp and MPG be enabled, that'd be snazzy. I'm just going to eat it big and buy from Edmunds anyways, so in a week or so when I take my gauges out, I'll do it.

It's really easy to take the gauge cluster out though, takes about 2 minutes total, just 2 screws. How come you haven't taken yours out?

Sodium Duck · 03-11-2009, 04:23 PM

I'm assuming that the Canadian Yaris's have the same LCD gauge as the US Yaris's? Can you post a pic up of a gauge with the things you want turned on? I'm just curious.

In the above pics from Marty, you can see the things that the gauge can display, but isn't - if you look closely. I'd like to take a few shots of my LCD and see if I can see them too.

Just want to know what I'm trying to look for.

not sure how the gas gauge is but would probably work too

BINGO!!! i was just about to say that.. u dont need to buy anything.. just take off the top layer carefully on the lcd and then turn it!!!
