I didn't understand your language, so I don't know what is the problem. If you want to connect it to so standard computer video output, you need to find/buy video controller. In new devices there is only one chip and in very old ones there are MCU, DAC+pixel clock extractor, HV and VS separator. All this stuff is fed to LCD display using proper timing. I was trying to do something like this, but was stuck with proper timing problems. I think, that like in B/W monitor, there are some specific timing and sequence features. In this particular B/W monitor the critical part is timing of the beginning of the frame: I need to set HS and VS signal for some time, then remove HS keeping VS for a while. And it is very critical and not properly described in datasheet. It seems to be standard VGA/SVGA screen with uncompressed video input.

I find great this! I try turn on a Sharp LCD LM80c36, but almost complete lost. I found some little info about display, but no can get it working. Can you help-me to do some similar? http://dinf.unicruz.edu.br/~hernandi/index.php?mostrar=noticiacompleta&id=0115230077 You site is great! Hi. I find great this!
