Hi,

 

My small Philips TV broke (DVD drive malfunction), and upon disassembly I found a AUO a085fw01 v7 LCD panel inside.

From the datasheet (  a085fw01 datasheet.pdf   908.1KB   4 downloads), it looks like quite a job to get it to do anything meaningful

 

How would I go about using this with a Netduino, is it even remotely possible for a hobbyist like me?

I believe I would need some sort of controller and a .netMF driver (can these be some kind of generic or does it have to be tailor made for the specific panel)?

 

Lots of novice questions  I just want to know if I should put the LCD in the thrash.

IMVHO it will be rather hard - as you can see in the datasheet, the LCD requires complex driving signals with precise timing (e.g. t_CPH is 99 .. 107 ns) and multiple voltages (for an overview how to drive LCD with a microcontroller have a look for example at AN658). You'd also need some serious tools for troubleshooting, like oscilloscope and/or logic analyzer.

 

There are microcontrollers with dedicated (hardware) LCD drivers, e.g. STM32F427/37, which makes it a little bit easier, but still it is going to be a lot of work...

 

Much easier is to use the existing driver board from the TV and hope it has some usable interface. Almost certainly undocumented, so you'd need to decode the protocol...

Hi CW2,

 

Thank you for the feedback.

It seems I might be a bit over my head in this
