Abstract
Seal material bars and methods for forming seal material bars, a seal material frame and a method for forming a seal material frame, and a method for forming a flat panel display. Bars of seal material are made by extruding a mixture of glass frit and organic compound. In one embodiment, the glass frit bars have joining features formed in them. Ceramic material is also extruded so as to form seal material bars. The seal material bars are placed between the backplate and the faceplate and glass frit slurry is placed between adjoining seal material bars. Alternatively, seal material bars having joining features are used by mating joining features of adjoining seal material bars. A heating step melts the seal material so as to form a sealed interior region. Alternatively, the bars of seal material are used to form a seal material frame that is disposed between the faceplate and the backplate. The seal material frame may be formed using seal material bars with glass frit slurry disposed between adjoining seal material bars. Alternatively, the seal material frame is formed using seal material bars that have joining features.
