How to connect and control such lcd?

Question

Electronics

Good afternoon, for my project on raspberry I need several types of screens, like these and I'm just delving into this topic, I found different screens that can suit me and I still don't know how to connect them and how to manage them, I'll divide it into 2 parts question
1 ) all similar lcd screens have a standard cable or each one may differ in the number of contacts, etc. ?
2) can i connect them directly to the raspberry or should there be another separate driver for each screen
3) If my questions are stupid enough, what can i read to learn more about screens and working with them, thanks

Answer 1

1. May vary.
2. Both options are possible. Depending on which interface the display controller uses (hereinafter), which interfaces and Raspberry GPIO pins are free and / or allow sharing with other components of the circuit being developed.
3. It is necessary to go from the brand of the display to the brand of the controller installed in them. From the brand of the controller and / or display - to a typical wiring diagram. And from the brand of the controller - to finding a ready-made software driver for Raspberry or writing your own. Something like this.

Answer 2

By the name of the display, you are looking for a datasheet for the display and from there you take the connection diagram and the data exchange protocol.
According to the datasheet, it will be clear that a separate controller is needed or it can be connected directly. In the same datasheet, you study the data exchange protocol and write your image output code, if you're lucky, it will be more or less typical and there will already be examples in Google.
I want to say right away that the probability of finding a datasheet for some unknown display is extremely small.
Guaranteed to start with raspberries if you buy such a display with a controller included
Purely for example, a display with a controller that can be plugged directly into hdmi https://aliexpress.ru/i/1005001658631882.html
