Abstract: A display panel includes an amorphous silicon gate driver in which a lower voltage than the gate-off voltage output from the gate driver is applied to an adjacent stage as a low voltage transmission signal.

Abstract: There is disclosed a bioceramic matter as small in size as 300-475 mesh, comprising about 60.5-70.5% by weight of silica (SiO.sub.2), about 10.7-13.7% by weight of alumina (Al.sub.2 O.sub.3) and about 10.8-20.8% by weight of an effective-ingredient mix. The effecitive ingredient mix comprises about 1.4-3.4% by weight of ferric oxide (Fe.sub.2 O.sub.3), about 0.3-0.7% by weight of magnesium oxide (MgO), about 0.8-1.6% by weight of calcium oxide (CaO), about 1.5-3.5% by weight of sodium oxide (Na.sub.2 O), about 0.4-2.4% by weight of potassium oxide (K.sub.2 O), about 0.09-0.1% by weight of phosphorous pentoxide (P.sub.2 O.sub.5), about 0.02-0.2% by weight of titanium (Ti), about 0.02-0.2% by weight of manganese (Mn), about 0.02-0.2% by weight of selenium (Se), about 15-25 ppm of germanium (Ge), and about 2.5-3.5% by weight of silver (Ag).
