Title:
SYSTEM FOR MANUFACTURING PLANAR LIGHT SOURCE APPARATUS AND METHOD FOR MANUFACTURING PLANAR LIGHT SOURCE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/123996
Kind Code:
A1
Abstract:
The present invention addresses the problem of suppressing the occurrence of light leakage in a planar light source apparatus. This system for manufacturing a planar light source apparatus is provided with: a first adhesion part for adhering a prism sheet and a light shielding tape; a first image capturing part by which an image of the light shielding tape to which the prism sheet is adhered is captured from the thickness direction of the light shielding tape, and an image of a frame which accommodates a light guide plate by surrounding the side surfaces of the light guide plate is captured from the thickness direction of the frame; a calculation part for calculating the coordinates of outline points and a center point of the light shielding tape from the image capture data of the light shielding tape to which the prism sheet is adhered, and calculating the coordinates of outline points and a center point of the frame from the image capture data of the frame; and a second adhesion part for adjusting at least one among the position of the light shielding tape to which the prism sheet is adhered and the position of the frame, and adhering the frame and the light shielding tape to which the prism sheet is adhered, on the basis of the coordinates of the outline points and the center point of the light shielding tape and the coordinates of outline points and the center point of the frame.
