Abstract
A field emission display (,) includes a plurality of offset phosphors (,) and a cathode plate (,). Cathode plate (,) has a plurality of non-electron-emissive structures (,), a plurality of electron-emissive pixels (,), and a plurality of focusing electrodes (,). Offset phosphors (,) are aligned one each with non-electron-emissive structures (,) of cathode plate (,). Focusing electrodes (,) are disposed to cause a plurality of emission currents (,), which are generated by electron-emissive pixels (,), to be directed one each toward offset phosphors (,). Ions liberated from offset phosphors (,) are received by non-electron-emissive structures (,) of cathode plate (,), thereby ameliorating ion bombardment of electron-emissive pixels (,).
