    I know they used to exist in the late 1980's and early 1990's when the Nintendo Game Boy DMG-01 come out, and I see many backlit screen mods available, but has anyone seen a transflective LCD mod that gives me the OEM reflectiveness as well as the backlight? If not, how were screens like that built to be visible in both front light and when backlit?

    You would be correct in saying that a Game Boy display is graphical, especially with the border saying "DOT MATRIX WITH STEREO SOUND." That said, I'm modding the display that is there already with an add in backlighting kit that is readily avaiiable. However, I'm wanting to keep the reflectiveness for gameplay outdoors instead of having to rely on a honkin' backlight. I think I may have to mod my packaged mod to pull this off like I'm wanting.

    I am not clear on what you are trying to do. That is, if you are adding an aftermarket LED backlight, how would that affect the reflective surface that is already there? Are you looking to replace the GB screen or just modify it?

    In the link I posted, this example: https://www.displaytech-us.com/sites/default/files/display-data-sheet/64128K series.pdf
    shows retention of the reflective surface and a backlight. There are other examples in that Digikey link.

    If you are planning to replace the GB display, that could be a lot more complicated.

    Now, imagine if there was a way to leave that reflective sticker you peel off at about the 2 minute mark, but still have the backlight. I know there were displays then that had that capability.

    The GBA-SP (AGS-001 model) accomplishes the same thing I want to by having a color reflective LCD with a front light, though I've used many devices, such as watches, meters, etc that does what I'm wanting to do.
