Repurposing LCD car DVD player faceplate screen? :P
« on: December 28, 2013, 02:06:37 am »


Trying to figure out if this LCD can simply be fed a video signal, but not really sure where to start....

I'm wondering if the DVD_C_IN and DVD_Y_IN are a chrome/luma input...

The AUX_L, AUX_R and AUX_CVBS run to an AUX input connector on the front panel.

SCL and SDA appear to be for the serial touch screen.

D+, D- and USB 5v are for a front USB port...

Anyway! not the point... does anyone actually know what the IC used on this is? :P

According to Google, that would be a Terawins T101A. Datasheet here...

CVBS is probably the one you're looking for.  CVBS stands for something or the other, but its the same as composite video, i.e. the one you can feed from a single coax cable.

... and that chip is a Terawins T101A Video Display Controller, which happens to have 9 CVBS inputs (!) and is switchable by the I2C lines (SDA, SCL)

The Y/C lines also go to the chip.   

The datasheet is attached. (zipped, 2 part RAR files)...
I had to split it (RAR) since the file size limit is 1MB per file and the datasheet is 1.3MB
I had to ZIP the 2 RAR parts since the forum only allows ZIP upload, not RAR uploads directly.

You can also get it here from Electrotanya, but you might need an account, thats why I attached it too.

Thanks for the assistance, I shall look into this further.

No clue why I couldn't find the datasheet :p

Might need to modify this a bit...
