Screen abreviations help please

[Stormy]

hi, I guess the psp section is the best for this.  It kinda has to do with a psp mod...

Anyway, I am working with an lcd screen from Giant Plus and I cannot figure out what the abreviations for what each wire does.  Here is a list of which ones I need figured out:

NO.1: SYM.-STH1
NO.2: SYM.-INH
NO.3: SYM.-Q2H
NO.4: SYM.-CPH1
NO.5: SYM.-CPH2
NO.6: SYM.-CPH3
NO.7: SYM.-VSS
NO.8: SYM.-VB                        I know this is Blue
NO.9: SYM.-VG                        I know this is Green
NO.10: SYM.-VR                       I know this is Red
NO.11: SYM.-NC
NO.12: SYM.-R/L
NO.13: SYM.-STH2
NO.14: SYM.-AVDD
NO.15: SYM.-VCON
NO.16: SYM.-VGH                      Ground maybe?
NO.17: SYM.-VCC/VDD
NO.18: SYM.-DIO2
NO.19: SYM.-XOE
NO.20: SYM.-CPV
NO.21: SYM.-U/D
NO.22: SYM.-DIO1
NO.23: SYM.-NC
NO.24: SYM.-VGL                      I am guessing this is ground

This comes from the website :

If you need to look at that.  Specifically I want to know which wires might be "Hsync/Csync", "Vsync" and "Display State Line" but if you can help me with as many as possible that would be great.

Thanks!

This is an analogue lcd module, these are the interface pins directly into the display.

There is nothing here but the lcd module it is bare.

There has to be a analogue driver ic hooked to this display. Its that interface chip that gives you your sync signals and such.

this is as low a level display as you can go.

Yeah, this will be hooking up to a digital source, but according to Spectroplasm who did the work to figure out the video out for the original psp, you can hook up a digital source to the analog, it just won't be as pretty.  But anyway that is where I got the information.

here is the link :

(at the moment it does not seem to be loading the picture on my computer).

So based on his work and what I am thinking, this should work, right?

Ok this article talks about hooking up a computer monitor to the PSP.

What he is doing is taking the bit0 bit of each color and feeding that digital signal to the color inputs of a vga monitor and then he is taking the sync signals to drive the monitor in the correct timing.

The digital part of the signal will be very clean but the color and brightness of the monitor will suck.

He makes one small mention of the only way to get decent color and brightness is to hook up three digital to analogue converters so you would have full color and brightness range.

You monitor also has to be able to run the low resolution of the PSP and not very many any more will run under 640 x 480.

The conversion process would work for monitors NOT other lcd displays. Because you are feeding digital information into a converter system in the monitor.

There are signal timings call front porch, vertical retrace, horizontal retrace, blanking interval, and many more. The electronic control system in the monitor handles all these for you, even if you are feeding digital information into the analogue inputs of the monitor.

You have no such electronics with a bare display. Also the timing from one manufacturer of LCD display is different from another.

Not a simple process. If you want to run two displays then run an identical one to the one in the PSP
