摘要： A field emission display having an n-channel high voltage thin film transistor is disclosed. According to the present invention, a signal for driving pixels controls by the nHVTFT attached with each pixel, therefore, the signal voltage of row and column drivers is exceedingly decreased. As a result, it is possible to implement a field emission display capable of providing a high quality picture in a low consumption power, a low driving voltage and inexpensive to manufacture, and preventing a line cross talk using the nHVTFT. By using a cylindrical resistive body underlying a cone-shaped emitter tip, the present invention is to provide a field emission display having an excellent contollability and stability of the emission current, and a dynamic driving capability.

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.
