Hi - one of the enclosed pics is of the pcb in a monitor that actually drives the pixels.
Along the top edge you can see 10 blocks of traces that go to the screen.
Signals arrive on the relatively short connector on the right, arrowed, and go to the big ic (other pic) which presumably does all the work. The legend says the big ic is a S4L9245X01-50A.
I would like to relate the signals on the many-way connector to the screen to the pixels on the screen on an x-y basis, so that I can monitor the state of any individual pixel.
Out of interest, I would also like to send my own signals into the arrowed connector and make the screen show something.
To do all this, the datasheet for the S4L9245X01-50A would very handy
. Unfortunately, lg.philips is now out of business, and I can't find it anywhere else.
No doubt more recent monitors will have a similar arrangement inside, but before I try getting hold of one, can anyone tell me the generic name for the function of the big ic, so I can look at a datasheet? Something like "LCD screen driver"? Or what?
Also, any comments on the above welcomed.
Thanks,
