There are a lot of examples that can be mentioned. For example, photoelectric effect is used to create a image detector for "video camera" before it was replaced by iconoscope and later CCD.

Similarly, thermionic emission is used by vaccuum tube like cathode ray tube (CRT). CRT manipulates the trajectory of the electron to create images in CRT display/monitor.
