Patent abstract
A flat panel field emission device includes a black matrix formed from an electrically insulative material such as praseodymium-manganese oxide. The insulative black matrix increases image contrast and reduces power consumption. For field emission devices which utilize a switched anode for selectively activating pixels, the insulative material reduces or eliminates problems associated with short circuiting of the pixels.
