The light guide plate includes first columnar microstructures extending along a second direction perpendicular to the first direction on the light-emitting surface and columnar microstructure groups with second columnar microstructures, which are 1-15 times the number of the adjacent first columnar microstructures, between the first columnar microstructures extending along the second direction on the light-emitting surface. A first width of the first columnar microstructures is larger than or equal to a second width of the columnar microstructure groups along the first direction. A first height of the first columnar microstructures is larger than a second height of the columnar microstructure groups.

Abstract

The present disclosure provides a backlight module including a plurality of light-emitting elements and a light guide plate, in which the light guide plate includes a light-emitting surface, a bottom surface opposite to the light-emitting surface, and a light-incident side connecting the light-emitting surface and the bottom surface. The light-emitting elements are disposed at the light-incident side along a first direction, and the light-emitting surface includes a first region near the light-incident side. The light guide plate includes a plurality of columns extending along the first direction and disposed in the first region of the light-emitting surface and a plurality of microstructure groups, in which each microstructure group includes a plurality of microstructures arranged along a second direction different from the first direction, and each microstructure connects the adjacent two of the columns.

Abstract

A method of manufacturing a metal mask includes providing a growth substrate with a conductive surface. Then, a cover pattern is formed on the conductive surface, which has at least one opening and an insulated surface touching the conductive surface. Next, using the cover pattern as a mask, a first electroforming is performed to form a mold part on the conductive surface. The mold part fills the opening and has a conductive pattern surface touching the conductive surface. The conductive pattern surface is flush with the insulated surface. After the first electroforming, the growth substrate is removed, while the cover pattern and the mold part are reserved. After removing the growth substrate, a second electroforming is performed to the conductive pattern surface of the mold part to form a metal pattern. Afterwards, the mold part and the cover pattern are removed from the metal pattern.
