Anyone built instruments using OLED display?

[robcollingridge]

Thinking of using a high resolution 7" OLED display for all the instruments in my next car. Anyone done this?

I was playing with a Raspberry Pi this weekend, thinking it could be used as the basis of the instruments and display. It has HDMI 1080p output.

I've been looking at my perfect instrument pod design for a while and though the OLED display would be the best way forward, providing better clarity and layout, and the ability to update the instruments later.

My initial thoughts are here:

Had a play with HTML 5 yesterday and came up with this so far. It's static and not animated but, I'm getting there:

Before I spend too much time on it, I wanted to know how eaasy it was to use a ~7" OLED display at 720p or 1080p resolution.

I want to generate the whole display in HTML5 and it will be moving/animayed in HTML5 too.
Come back in a week to this test page and you will see what I mean:

Note: This page will only work in a browser that supports HTML5!

I simply want to use a low power processor to do it. Currently using a Raspeberry Pi device running Linux and this outputs what I need as 1080p and via HDMI.

I'm not looking to do this in scale or on a commercial basis. I'm planning a one-off car for me :-)

Would a display like this pass an IVA test? That's all that matters to me.

I like what you're doing, it's something that has always interested me as well but I think it's going to be a wasted effort:

It runs on PC/Andriod/iDevices, with the cost of a 7inch display and RPi you're probably better off getting a cheapo 7inch Android tablet and running dash command on it.

Dashes are on the forum:

Unfortunately it didn't build the community I'd have hoped so it's kinda dead in there, you might be able to find more dashes on the Mp3Car forum.

I want a bespoke layout and I'm not interested in 3D graphics, superflous colours and the like. I want simplicity and clarity, in keeping with the rest of the car. This is pretty much the final layout and design as I want it to be:

It's laid out and scaled for a 1280 x 720p screen for now. I just have to change the scaling factor to make it 1920 x 1080p. Working on the animation aspects now :-)

Interesting solutions but, seem to be assuming OBD I interface to any Android tablet?

I'm not going to have this as I'm going to be using a bike engine, which is essentially a black box. I'll take tacho feed off the ECU but, everything else will be a bespoke loom and electrical interfaces to all the sensors, including A-D convertors.

Currently have a Digidash II in my Fisher Fury R1 and it's this that I'm trying to replace in my next car.

This is the kind of display technology I'm interested in:

Was at Goodwood Festival of Speed yesterday and noticed the BAC Mono has a display like I'm planning but, it is mounted on the steering wheel. Good to see that this is viable though:

Interesting to see that they are also using the same waterproof dash switches that I've used in my Fisher Fury R1 and plan to re-use again.

Hi,

Thanks for that, very interesting: http://www.gems.co.uk

The problem is it isn't exactly what I want :-( I've designed my perfect instrument layout and this is it:


The GEMS display are fairly low resolution. I've worked out that I can get away with 1280 x 720 or 1280 x 800 pixels.

[robcollingridge]

I'm using a Google Nexus 7 tablet to test out the design and ergonomics (7" display at 1280 x 800 pixels). Don't have a view on the final display hardware yet.

[robcollingridge]

Main reason for HTML5 was that it was quick and easy to do, I created what I wanted in a few hours, including all the animations I needed and it seems pretty fast and responsive on quite low powered processors. Given that I am going to put bespoke processor and networking in my car for other stuff (data logging, etc.), it makes sense to me. It also fits with my preferred route (and experience) of using the QNX O/S and is also how they are doing stuff like this: http://www.qnx.com/solutions/industries/automotive...

I'm open to other suggestions and ideas though. Tell me if there is a better way to do it that is not restrictive to the dash functions only please.

Well my Google Nexus 7 arrived yesterday, so I'll be testing out the ergonomics and readability of this over the this weekend. Have to say, the Nexus 7 tablet is brilliant. I've written a review on one of my other websites here: http://www.dreamgreenhouse.com/reviews/2012/nexus7...

Yes, a little bit 'techy', I use something similar in my custom home automation system :-) Will be interested to see how you get on. I've been looking at similar solutions. I need quite a few digital inputs and analogue inputs though.

Stuff seems to be moving along nicely:

I'm prototyping with a Raspberry Pi. I'm using this 9" display now too: http://hdmipi.com/
