Hi, sorry for answering so late ... In the repo there is a directory called "BOM" (bill of material) and in the text-file "others" there is the LCD which works:
LCD: (search on ebay for LCD 64x32) e.g. GLS Neu LCD-VATN 64x32 3V ST7567A I2C 15x12x2mm [LCD-AG-064032V-VIW W/KKK-E6]
Ah forgot to answer the other question - you simply can remove without much force the backlight from the LCD :)
Thanks for your replies :) I didn’t see the BOM folder ...
I found your lcd on eBay for about 15€ shipping included Is there a difference with another classic RGB lcd ? (Except the size maybe) I found this lcd on AliExpress, for about 2.5€ :

If I use it as “black/white”, is there a way it will work as yours (optically I mean, not necessary the driver) ? (After removing pcb and background led) Thanks for your help
No, OLEDs can't be used for projectors in general.
Actualy, the one I found was NOT oled according to the description.
Thanks for the link, I will buy it :)
You explained that it was a negative monocolor LCD. I wondered if it was necessary or if a conventional RGB LCD does the same job.
your project made me want to build mine :)
Ah sorry, you are right ... Just read "OLED" at the end of the title and missed the "not" before xD You can try, but you will have to change everything ... This would be a lot of work and would be very time consuming. If you do, I would be interested in your results :)
But I don't know how good the contrast will be ... perhaps black background is milky then. This small little LCD seems to have been build for projecting applications - but of course we don't know for real.
The contrast could be the issue with this RGB lcd, that why I’m thinking using it only in white/black, hopping it will be enough ...
Your small lcd seems to be design to feet in key : Q5-100-STARTER-KIT 64x32 Spi Lcd Switch & Breakout Board https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F132276707938
The electronic hardware shouldn’t be a problem, I’m thinking using an ESP32 to control display, get time through internet and maybe to project small icon of weather :)
My real issue in my project was what you solved : the optical hardware
I will let you know when I will receive the components and share with you my knowledge and my project if you want
I will maybe have more questions ^^
Niiiiice! Thank you for the link! That could be the reason why this LCD exists :-)
Looking forward hearing about your progress! :-)
Hello, I’m working a lot on this project and it start to work well. Until now I’m using the LCD 160x80 in SPI. But I would like to have it brighter so I will test the same LCD as you. Can you tel me more about the connection of this LCD : Which pin of the LCD did you connect to 3.3v ? (On datasheet there are pins for dc/dc converter and one for 3.0v) Why did you keep the led pin ? Thanks for your help
I don’t know how to send photo of my project
Hello,
ah yes, why did I keep the Pin for the backlight - I don't know to be honest ... The back light is removed anyways xD Perhaps to be able to use it for different applications which need backlight.
I connected Pin 8 to 3.3V. You can open the schematic with KiCad.
Hi guys, just started looking for LCD glass and found something like this in EU: https://allegro.pl/oferta/art-lcd-vatn-64x32-3v-st7567a-i2c-15x12x2mm-whiten-6754828746 for some 3 Euros, shipping included. josef
Hey @shufps
Do you have a recent link to an LCD display? This is an awesome project and I'm finding it hard to locate a suitable LCD.
Thanks, Zoltan
https://allegro.pl/oferta/art-lcd-vatn-64x32-3v-st7567a-i2c-15x12x2mm-whiten-6754828746 is still valid... Josef
... whoops sorry, it has not been query for me... ;)

I had a look at that, but due to the current COVID-19 situation that website have stopped delivering to non-Polish addresses... :(
Appreciate the reply anyway!
Any chance you could provide an aliexpress link? I've tried the link above and it's in Polish, and Google's translate page feature isn't great. I've tried searching the line from the BOM, even parts of the line but I can't seem to find what I'm looking for....
Anyone ever found a suitable replacement for the led screen in the project? I tried ordering through the Polish webshop but there is an issue with delivery and I probably lost my money. I have been unsuccesful finding a replacement.
If you are able to change the library you can take any lcd screen. I'm using 0.96in tft display 80x160 with arduino based electronics and it works well
€ 1,69 11% Off | 2022 New 0.96in TFT Display Module IPS Color Screen SPI For LCD 80x160 ST7735 Drive Welded Spliced Link https://a.aliexpress.com/_vMIfpr
But that's not a negative LCD, right? So how would you use that for projection?
You have to remove the backlight
Actually just bought me the black version of this one to try out. It comes without the backlight.
I'll be figuring out the library part myself so I learn something from it. It's my first real ESP32 tinker project.
Thanks for the link, I didn't saw it
But the density of pixel is not as good, and the issue I didn't solved is a way to have an homogeneous light before the lcd screen

But the density of pixel is not as good, and the issue I didn't solved is a way to have an homogeneous light before the lcd screen
I assume you mean the light behind the LCD screen? Did you use some form of condensor to try and get an homogeneous light?
Yes the light behind the lcd screen
I tried several things but I always have something not homogeneous :(
What do you use for it ?
I just started looking into all this and I have no experience with these kind of projects. But I bought this one as a first attempt. And I thought I just reflective tape or aluminum foil for extra spread.
The link does not work for me
You have to remove the backlight
How hard is it to remove the backlight?
The link does not work for me
Does this work?
Yes the link works
I already tried this but it's not homogeneous and you saw it on the wall

OK. what gave you the best results?
The best I found was a led with this :
€ 0,98 | Cree XPG lens Diameter 23.5mm (Belt holder) 5 degrees LED Lens, glass Condenser lens, https://a.aliexpress.com/_vl5RYv
But not perfect
And as the screen is bigger, you see halo on the wall :(
Hello, Very nice project, I was thinking about it for years but I didn’t find how to find the lcd. Where did you buy the lcd ? What’s it with backlight led that you removed ? Thanks for your project Regards
