随着 3D显示技术的飞速发展和产品线的逐步成熟, 3D立体显示技术成为平面显示 器发展的重点之一。 目前, 市场上主流的 3D显示技术有色差式、 偏光式、 3D快门眼镜 (3D shutter glass) 式及裸眼 3D。 其中, 3D快门眼镜式技术以其立体效果突出、 画面分 辨率高、 液晶模组成本较低等优势得到了市场的广泛认可。
3D快门眼镜式显示技术通过把一帧图像拆为两帧分别对应左眼和右眼的图像, 将这 两帧图像在液晶显示屏上连续交替的显示, 同步地控制快门眼镜的镜片开关, 使左右双 眼均可以在恰当的时间看到相应的图像。 最终, 左右双眼看到的两幅不同图像在大脑中 综合形成原始图像的立体效果。

出现上述两种情况的原因是, 情况 1和情况 2重置前的 GLASS状态是不同的, 在重 置后, TV会无条件认指定画面开始, 比如左眼画面, 但是由于控制 3D shutter glass的控
制单元 (如图 2所示) , 其根据 STV讯号来持续交替的发送左右眼镜讯号, 即 GLASS 的状态会根据到来的 STV讯号不间断变化。 在用户会感觉到左右眼图像错位时, 通过触 发设置在 3D快门眼镜上的重置按键, 才可以消除错位现象。 因此, 如何解决上述问题, 使得在 2D模式转换为 3D模式时, 不出现 3D快门眼镜 的错位现象, 减少使用者 于错位现象产生的昏眩和不适感, 乃业界所致力的课题之

为使本发明的目的、 技术方案和优点更加清楚, 以下结合跗图对本发明作进一步地 详细说明。
请参考图 3 , 图 3是根据本发明一实施例的控制快门眼镜的控制架构图。
认图 3 中可以看出, 该控制架构的输入端输入 STV 讯号和 3D 启动¾号 (图示 3D Enable) , 经过控制, 输出端输出左眼眼镜控制 ¾号 (图示 Left glass)和右 El艮眼镜控 制讯号 (图示 Right glass ) 。
图 4是根据本发明一实施 的控制快门眼镜的控制系统, 参阅图 4, 控制系统 4包括 接收器 40、 计时器 41和重置器 42。 该控制系统优选采用 FPGA芯片来实现, 可以将实 现上述功能的 FPGA芯; t设置在快门眼镜的框架中。
接收器 40, 其接收 3D启动讯号和具有设定频率 (例如 120Hz) 的帧劇新讯号 STV。 如图 5所示, 在 2D模式时, 每相邻 STV正源触发间隔 (120Hz) 对应 2D画面显示时的 一左眼影像讯号和一右眼影像讯号。在切换到 3D模式后, STV ¾号按照设定频率(120Hz) 交替对应于一左眼影像讯号和一右眼影像讯号。 而且, 3D模式开启时, 即在 3D启动讯 号为高电平时刻, STV讯号进入重置状态。 在这个重置状态过程中, 等待下一个 STV讯 号的时间大约为 50ms, 而一般两个 STV讯号的时间间隔是设定频率的倒数, 本实施倒中 是 l/120 -fe:=8.3ms, 该重置状态为 8'1'¥ ¾号的特殊时期。
计时器 41 , 其耦接于接收器 40, 以 3D启动讯号的高电平时刻为起始点, 每侦测到 一 STV讯号的正源触发时則重新计时。 如图 5所示, 第一次计时是认 3D— Enable的高电 平所对应的箭头 (图中 "I") 到其后的第一个 STV ¾号的正源触发。 由于在此阶段 STV ¾号处干重置状态, 其重置时间大约为 50ms, 因此第一次计时^间被认为是判定是否进 行左右眼控制 ¾号重置的关键点。
重置器 42, 其耦接于计时器 41 , 在计时器 41计时到一帧剧新讯号的正源触发的时间 大于设定时间时, 其在该幀刷新讯号的正源触发时刻将左右眼眼镜控制讯号进行重置, 使得快门眼镜的左右眼眼镜幵启情况与左右眼影像讯号相匹配。
优选地,该设定时间大于 STV讯号的设定频率的倒数且小于幀刷新讯号的重置时间。 在本实施例中, 设定频率为 120Hz时, STV -讯号重置时间大约为 50ms, 则设定时间应该 大于 l/】20s (大约 8,3ras) 且小于 50ms。
在本实施倒中, 设定时间为 iOms, 如果†时器 41的第一次计时时间大于 10ms, 则 说明 STV讯号处于重置状态。在重置后的第一个 STv 号的正源触发时刻, 将对应于一 指定影像¾号 (一般为左眼影像讯号) , 即电视 (TV) 画面将丛指定画面开始, 如图 5 所示的左限画面, 那么此时重置器 42对左右眼眼镜控制讯号进行重置, 即无论之前 EI艮镜 (.图示 Glass)的状态是左眼眼镜控制讯号还是右限眼镜控制讯号, 都将在第一个 STV讯
号的正源触发时刻重置为与指定影像讯号一致的眼镜控制¾号,如图 5所示的左眼眼镜控 制讯号。 由于此时 TV画面是左眼画面, 快门跟镜受到左眼眼镜控制¾号的控制, 幵启左 眼眼镜, 使得画面和眼镜开启情况相匹配, 消除了在幵启 3D模式后, 出现的左右眼错位 现象, 避免了使 ]¾者产生昏眩及不适的情况。
图 6是根据本发明一实施 ^的控刺快门眼镜的控制方法的流程示意图,请同时参考图 4和图 6[:
接收器 40接收 3D启动讯号和具有设定频率的帧刷新 ¾号 (歩骤 S610) , 帧刷新讯 号按照设定频率交替对应于一左眼影像 ¾号和一右眼影像¾号, 其中, 在 3D启动讯号为 高电平时, 帧剧新讯号进入重置状态。
†时器 41 以 3D启动讯号的高电平时刻为起始点, 每侦测到一帧副新讯号的正源触 发时则重新计时 (步骤 S620) 。
重置器 42在计时器 41计时到一帧刷新 ¾号的正源触发的时间大于设定时间时, 其在 该帧 新 ¾号的正源触发时刻将左右眼眼镜控制 ¾号进行重置 (步骤 S630) , 使得快门 眼镜的左右眼眼镜开启情况与左右眼影像讯号相匹配。
本发明通过在控制 3D快门眼镜的控制系统中加入一个侦测 3D启动讯号的机制, 在 侦测到 3D启动¾号为高电平时, 计算到达帧刷新¾号 (STV) 的正源触发时间是否大于 设定值,在大于设定值时对 3D快门眼镜进行左右眼眼镜控制¾号的重置, 使得左右眼眼 镜的开启与左右眼影像讯号匹配, 能够有效地消除 3D快门眼镜的错位现象, 减少使用者 由于错位现象产生的昏眩和不适感。
以上所述, 仅为本发明较佳的具体实施方式, 但本发明的保护范 并不局限于此, 任何熟悉该技术的人员在本发明所揭露的技术范围内, 可轻易想到的变化或替换, 都应 涵盖在本发明的保护范圈之内。 因此, 本发明的保护范围应该以杈利要求的保护范围为
