A glass panel processing method includes a first deformed portion formation step in which, in order to form a via-hole in a glass substrate, a first deformed portion is formed to a first depth from the upper surface of the glass substrate through irradiation with a laser beam along a planned via-hole line, a second deformed portion formation step in which, in order to cut the glass substrate into unit cells, a second deformed portion is formed to a second depth in the glass substrate through irradiation with a laser beam along a planned cutting line, and an etching step in which, the glass substrate with the first deformed portion and the second deformed portion formed therein is etched such that etching of the glass substrate along the planned cutting line is completed before completion of etching of the glass substrate along the planned via-hole line.

Method of processing glass panel

A method of manufacturing a flexible OLED module includes: forming a polymer layer on one surface of a base substrate; forming a thin glass sheet on one surface of the polymer layer; forming multiple OLED elements on one surface of the thin glass sheet; forming a protective layer on one surface of the thin glass sheet to cover the OLED elements; separating the base substrate and the polymer layer from each other through separation of the sacrificial layer by laser lift-off (LLO); and cutting the thin glass sheet and the protective layer to provide multiple unit OLED modules each including the OLED element.

Method of manufacturing flexible OLED module

Provided is a backlight unit for a key of an input device. The unit includes a light guide plate and at least one light emitting unit. The light guide plate is formed of flexible transparent resin and has a light guide pattern portion in which a plurality of engraved or embossed patterns are formed in a plurality of requirement character shapes so that light can be diffused and scattered at desired luminance from a necessary light emitting portion, using a minimal number of light sources. The light emitting unit is installed at a side wall of the light guide plate.
