No. This display is a DSTN. You need a special video chip or card that is able to provide DSTN signal.

OR

use an older notebook (486 or worse) without (or cracked) screen. Those notebooks used DSTN displays (of course it depends on the exact model).

Just for information: the contrast and speed of the DSTN is low.

ok, i know the contrast is low and the display is slow, but i don't need anything special for the linux cmd line player... all the pc is working, just thinking how to connect this display... so, is there any pci/agp/isa card i could use?

Unfortunately, none of the ordinary video cards is able to drive this display.
In the case of TFT, there is a possible way, using the feature connector, but only in 16 colors....in your case the display is DSTN. The driving method is different.
Without special electronics skill, you won't be able to use it.

I suggest to use a simple 4x20 LCD, or a graphical LCD and drive it with a PIC.

It is very unlikely, but if you got a video card with a chip that is supporting LCD (eg. certain Chips series) perhaps it works. Personaly I do not recommend this, because it does not worth the effort.
