Abstract

一种纸牌，表层为点阵光栅层，只在点阵光栅的中部设置标志意义信息，可有效防止较小视角偷窥标志意义信息，有助于纸牌打牌的公平竞争。

Description

点阵光栅防窥视纸牌
技术领域
本发明涉及一种用纸或塑料等材料制作的纸牌。
背景技术
通常的纸牌有扑克、长牌等，在拿牌和打牌过程中，有些人爱斜着偷偷窥视别人手中的牌，导致不公平竞争。
发明内容
本发明的目的是针对上述状况，提供一种改进的纸牌，它不仅可有效防止偷窥，还提高了纸牌的强度，使纸牌更加坚韧耐用。
本发明的技术方案是：一种纸牌，有正面和背面，纸牌的正面表层为点阵光栅层，纸牌的正面的标志意义信息区点阵光栅的中部设置标志意义信息，纸牌的正面的标志意义信息区点阵光栅的边部设置标志意义信息区其它意义信息，纸牌的正面的其它意义信息区点阵光栅设置其它意义信息区其它意义信息，标志意义信息区其它意义信息与其它意义信息区其它意义信息内容一致。点阵光栅也可称为阵列光栅、圆点光栅、球形光栅等，主要用于制作立体视觉图，但可利用其变化视角图像不同的特点用于防止较小视角偷窥的目的，小于一定视角就看不到纸牌标志意义信息。纸牌可为扑克、长牌等牌。纸牌并不是指纸做的牌，塑料或其它材料制作的纸牌仍是纸牌。
本发明的有益效果是：由于本纸牌的正面表层为点阵光栅层，可有效防止较小视角偷窥标志意义信息，有助于纸牌打牌的公平竞争。
