Hello Kenesbek
On the internet:

4

thanks, I already tried this and it works, but I have another question, I want to display my image

5

They don't have a library for that?

6

Actually this tutorial:

...says they can only display text. As you can see in the image it is possible to "draw" basic shapes.

7

Ah yes - it's not an LCD it's a TFT so you should be able to display anything.

8

this is a 16x2 lcd but it cannot, but I have st7735 it can, but somehow it doesn’t work out for me and gives an error https://youtu.be/-h9Vm0Ow_Is
I need something like this

9

Yes you are right

10

The problem though is the need for an Arduino Library - looks like images are displayed via a parallel interface.

This search brings some fruit to the table:

I used these OLED Screens, there is an application to convert images to LCD, I don't know if it will work for you.

thank you i will try now

I thought the Adafruit ST7735 and ST7789 Library hit the nail on the head. Note though, colour images can be heavy mb, hence some developers add an sd card slot for more memory.
