Application of Lead-Free Glass to Barrier Rib Materials in Plasma Display Panel

The effect of RO components variation on some properties was studied in Pb free glass frit for PDP (Plasma Display Panel). One of the main components, BaO, was replaced progressively at fixed concentration of alkaline earth oxides. We studied the transparency, thermal expansion, softening point, and the high temperature microscopic behaviors of glass frits and TG(thermal gravimetry) of raw material. The compositional dependence of those properties was discussed from the view points of compositional diversity and production process of Pb free glass frit.

The present study is mainly focused on the evaluation of interface reaction between ceramic fillers and phosphate glass matrix for barrier ribs in PDP. The samples were prepared by dry milling for frits with a mean particle size(d50) of 1-2㎛. The frit was mixed with ceramic fillers (Al2O3, ZnO) and was fired at 550°C for 30 minutes. Interface reaction was observed by measuring the weight change of fired samples as a function of immersion time in 90°C de-ionized water and in 60°C acid solution. Fired samples were characterized by differential thermal analyzer, scanning electron microscopy, X-ray diffraction and ion dissolution was analyzed by inductive coupled plasma measurement. The results suggest that properties of barrier rib depend on the crystallization behavior and interface reaction between the fillers and the glass matrix.

Powder Content

Barrier ribs of plasma display panel (PDP) were prepared via injection molding of thermally curable paste. The paste composition was optimized by considering the effects of powder content, binder type and content on the viscosity of paste. Various types of molds including stripe, honeycomb, and meander were prepared using UV lithography. In this study, main causes ofdimensional change during sintering of meander type barrier ribs produced by injection molding process were investigated by changing powder content in the paste. The results indicated that sintering stress generated in the barrier rib is not balanced at the points where the ribs are curved, causing dimensional change in the ribs.
