I also have a hard time understanding the question, but reading the text, it asks a different question:
âThe thing is I m going to need to display stuff on it so I need character gloves and little graphics and stuff like that. Are there any standard glyphs or libraries for resolutions that small?â
Because of that and the use of âone colorâ, I think/guess the OP has a 80Ã20 display that isnât black and white (say a LED panel), and looks for fonts that can be used on it (I would go look at https://int10h.org/oldschool-pc-fonts/ or https://damieng.com/blog/2011/02/20/typography-in-8-bits-sys., or look at old Mac and Windows bitmap fonts for those (warning: copyright laws may apply)) and, possibly, libraries to show an UI on it.
