Lapping Plate

Lapping Plate for LCD panel cleaning is a precision abrasive plate with a repeated concave–convex microstructured surface, produced by gravure printing and repeated microstructure coating of abrasives onto a substrate. It is used to clean an LCD panel before polarizer attachment. GRISH states that the plate comprises a grinding layer, buffer layer and mounting-function layer. The manufacturer lists nominal plate diameters Ø150 mm, Ø300 mm and Ø400 mm, with custom sizes available. Its table includes two total-thickness values written 11+0.2 mm and 4.1+0.1 mm, depending on product type, but does not map thickness to diameter or model; this information remains unassigned and requires source confirmation. The original row labeled Abrasives lists plate diameters, not actual abrasive mineral composition; no abrasive material or grit is certified. Performance statements are external GRISH manufacturer claims, not independently validated HANS specifications.
