Do you have any idea about this LCD?

Is it possible to interface with PIC?

and is it possible to find a controller and attach to the LCD?
or is no solution to put on PIC project?

If you read the forum PCM Programmer gave you the link to then you will see that a PIC is not powerful enough nor contains the memory required to drive a graphics LCD with that resolution.

I've done this with a larger LCD (640x480). But it was obvious that the processor would never come close to handling the timing that the display needed directly: it took a lot of external hardware to do it, including an oscillator and counter to grab the data out of memory and feed it to the display. It was an interesting project, but I came away feeling that there were much easier ways to do it.

LCD controllers are a bit of work. Xilinx has CLPD's that if you invest in mastering VHDL or Verilog you can with the timing specs from the LCD manufacturer create a controller to work with the pic. Now the contoller isn't always enough since video ram is also needed. The PIC gets DMA access to video ram via your controller and the controller manages the LCD refresh timing. After all of that all you can change is pixels so you then need fonts
and cursor control. Commercial controllers have this done for you Ex T6963
all the pic needs is the code to send in commands.
