Abstract
The invention relates to a large-dimension light guide plate glass and a manufacturing method thereof. The method successively comprises the following steps: (a), cutting a glass original sheet with a thickness of 1 to 5mm into a glass plate with a dimension of 55 to 75 cun; (b), edging the glass plate, and afterwards, polishing at least one edge portion of the glass plate; (c), performing disc-brush cleaning on the polished glass plate by use of deionized water, then blow-drying the glass plate by use of an air blade, irradiating light from the bottom of the glass plate, examining the surface quality, observing whether a poor point-like defect, a poor linear defect, a spot defect and a broken edge defect exist; (d), rejecting unqualified products comprising the defects, and afterwards, printing printing ink on any one surface of a qualified glass plate to form a shading net point; (e), placing the glass plate printed with the printing ink in a temperature of 120 to 200 DEG C for drying for 10 to 30 minutes; and (f), adhering a reflective film on the surface, which is printed with the net point, of the glass plate, such that internal structure reshaping to a certain degree can be performed on glass while the printing ink maintains dry, and the strength is improved.
