導光板構造及びその製造方法

Light guide plate structure and method for manufacturing the same

Abstract

【課題】局所照明を実現し、光漏れを防ぐ導光板構造及びその製造方法を提供する。 【解決手段】導光層と少なくとも1つの遮光線を含む導光板構造に関し、遮光線はインクを含み、導光層内に設けられて、導光層全体から透過される光を遮断する。遮光線は、導光層内の個別の領域にのみ光を透過させるため、または光漏れを防ぐために設けられている。前記の導光板構造の製造に関し、導光層に表面改質が行われ、インクを導光層に浸透させて、導光層に遮光線を形成するべく、導光層の改質された表面にインクが印刷される。 【選択図】図2
PROBLEM TO BE SOLVED: To provide a light guide plate structure achieving local illumination and preventing light leakage, and a method for manufacturing the light guide plate structure.SOLUTION: In a light guide plate structure including a light guide layer and at least one light shielding line, the light shielding line includes an ink, is provided within the light guide layer, and blocks light transmitted from the whole light guide layer. The light shielding line is provided to transmit light only in an individual region within the light guide layer or to prevent light leakage. In a method for manufacturing the light guide plate structure, surface modification is performed on a light guide layer, and an ink is printed on the modified surface of the light guide layer so that the ink is permeated in the light guide layer and a light shielding line is formed in the light guide layer.
