Is there a SLR digital camera that can take pictures with a display screen?

Yes! Olympus E-330 can shoot with liquid crystal and optical viewfinder, but other brands of digital SLR don't have this function, but now a Korean company has developed a liquid crystal viewfinder, which can make these SLR realize liquid crystal framing. Its principle is to install a display screen with a camera in front of the optical viewfinder, and see the objects in the optical viewfinder through the camera, so as to realize LCD framing. The name of this viewfinder is Zigview SLR camera LCD viewfinder. You should be able to search it online. As for wireless remote control shooting, you don't need to modify it yourself as the one downstairs said. In fact, many SLR cameras have the function of infrared remote control shooting.
