It's the same thing in reverse. You can use a camera to capture a light field, and then a screen with a complementary lens to project out (roughly) the same light field. In fact, given the principle of the reversibility of light, if you had a screen the same size and pixel density as your camera sensor you could use the exact same lens array to output a close approximation of the captured light field, without any post-processing of the captured pixels!
