ABSTRACT:
A liquid crystal display system has a first translucent sheet 20 having at least one pixel electrode 43 driven by a transistor 26, and a second translucent sheet 22 having a common electrode 32. The first and second sheets 20 and 22 are sandwiched about liquid crystal molecules 24 for controlling the passage of light. A field emission device (FED) light source 70 is adjacent to the pixel electrode 43, the FED light source 70 having an emitter plate 75 coupled to an anode plate 73. The FED light source 70 replaces the CCFT 54, reflector diffuser 60, metal sheet 62, and reflector sheet 56 used in prior art LCD systems.
