LCD Hack - Is this possible?

Hi guys

I have just salvaged this backlit LCD display (I beleive) from an old photo frame. Pictures are attatched, but it is a 761000937 E203460 display. The motherboard of the photoframe also contains an AUG375 (whic I believe is an SD/USB card reader) and also a Cheertek CT674-LF which I think is a display driver (I can't seem to find a datasheet for this).

My question: is it possible to connect this to the RPI/Arduino/Something? is there a driver board I can buy!!

Thanks Guys!!

It is generally not possible to reuse these without access to the data from the manufacturer. Even with the data, it will be difficult to drive without additional circuitry. There are driver ICs but using them requires knowledge of the display. The ICs are TQFP package, so are not easy to use without creating a PCB.

Judging by the number of pins I would guess that this display is one that uses LVDS and checking out similar ones on Alibaba (10.1 Inch Tablet Display H-101d-1ba 73002001242c E203460 235x143mm Thinckness 4mm 60pin - Buy Tablet Lcd Display,Display…)

What I think you might be looking for is something along the lines of these, it will be cheaper than making one yourself.

And also Tom, bear in mind that wiring up from that flat-flex to the board is not easy, and you'll also likely need a DC-DC converter to supply the voltage for the LED or CCFL backlight.
A fair bit of effort basically.

yes the voltages could very well be all over the place I would measure the voltages still in the original device if you can then scope out the video signals to get an idea of what you can do with it.

Bear in mind that a LCD with composite video input is about £10 from EBAY as a reversing Camera system!

I have a "new" display that I wanted to connect to my 'pi. So I have a full datasheet. I need three voltage supplies: something like -10V, +11V and +19V. Mind you: that's very approximate the specs state something like betwee 10.2 and 10.6. Oh, and for the backlight we needed a current source at something between 10 and 20V. So you'd go wrong if you assume it is a voltage that you measure at currently 17V... It can be 16V tomorrow when the weather is hotter....
