Is it possible to do that, like on a gameboy?
My console had the polarized film damaged. I replaced it with a linear one and the image is bad. SO i removed everything from the screen and used a ds lite backlight. In "regular" mode the image is bad too, but if I rotate the film, the image is crisp and nice, but the colors are inverted. So it't possible to use a 74hc04 like on a gameboy?
Thank you. From the link you provided : "A*,B*,C*,D* = data pour chaque driver de lignes."
So there are 4 lines that needs to be inverted.
The pitch is not that bad. The traces between the ASWAN and the LCD connector have vias, so you only need to solder wires to one side. And i think a SO chip will fit.
The problem is that i don't know which are the lines that needs to be inverted.

I've checked the pictures, but I'm lost. It's way different for the monochorme. It would be easier if someone made a pinout of the lcd.
But i'm correct when I say I need to invert 4 lines? Or there are only 2 like on gb? Or there are more?
And from the 74HC04 datasheet:
"]The 74HC04 provides provides six independent inverters with standard push-pull outputs. The device is designed for operation with a power supply range of 2.0V to 6.0V. "
The connector has18 pins. So far i've got:
I'm afraid it's not possible to go much further without using an oscilloscope or logic analyzer, or finding some who already did some reverse-engineering on the WS monochrome screen.
Have you tried other kinds of polarized film? Maybe there's one that will work with the screen as-is.

I've tried a few films from monitors, psp and some from aliexpress. All are the same. The image will be green, like on gameboy. And it's bad.
And all my 4 consoles have the front polarizer burned by sun. It's impossible to find circular polarizer at a decent price.
