LCD connections

That, obviously, depends entirely on the mechanical design of the LCD.

Which you have not told us...

And on the controller. Without controller, there could be 500+ contact points. With controller, there could be fewer than 10 contact points. You can use metal pins or rubber conductive pads or ...

So, we just have to probe his mind.

Thanks for the answer, but i haven't an electrical problem, i have a mechanical problem. For example, if i consider this display document.sharpsma.com/files/LQ043T3DX02_SP_122805.pdf how can i mount it on pcb? I'm looking for something that block lcd display on pcb

Still no idea if you talking about the physical mounting and/or the connector? The connector is a 0.5mm pitch Flat Flex Cable (FFC) connector, look them up. Digikey/Mouser have oodles of them. As for physical mounting, screens like these are all different, so there is no standard bracket etc. They are typically held in place with either glue of some sort, or a custom bracket, depends on the application.

You need 2 FPC mating sockets/connectors. A 4 pins for power and a 40 pins for data.

You can't really glue glass, but you can glue/screw plastic tabs/ inserts and hold the glass to the plastic housing. The best way to learn is to take apart some old laptops and see how they do it.
