摘要:
A field emission display device is disclosed. The device comprises an upper plate and a lower plate that are vacuum-packaged in parallel, wherein the lower plate is composed of matrix-addressable pixels, wherein the pixel formed on an insulation substrate comprises a field emitter array, a control thin-film transistor having a drain connected to an emitter electrode of the emitter array, and an addressing thin-film transistor having a drain connected to a gate electrode of the control thin-film transistor. Designing the control thin-film transistor to have a large parasitic capacitance between the source and the gate, one can obtain an active matrix display having a memory function and eliminate a conventional complex fabricating process of a memory capacitor, thereby simplify a panel fabricating process remarkably and largely increase the aperture ratio of a pixel. Furthermore, in the present invention, introducing glass for a substrate material instead of conventional single crystal silicon wafer, one can cheaply produce a large size panel and easily carry out a vacuum packaging that is indispensable for fabricating a field emission display.
