【具体实施方式】
请参阅图 1 , 图 1是本发明实施例的一种 3D显示系统的结构示意图。 如图 1所示, 本实施例的 3D显示系统 10包括显示装置 11和快门目艮镜 12。 其中, 快 门目艮镜 12包括驱动装置 13以及层叠设置的常白型液晶面板 14和常黑型液晶面 板 15。
本实施例中, 显示装置 11向快门眼镜 12提供显示画面, 并控制快门眼镜 12的开启时间。 驱动装置 13根据开启时间查询开启时间对应的亮度增幅比例, 并根据亮度增幅比例选择其驱动方式, 其中, 该驱动方式为仅驱动常黑型液晶 面板 15或者同时驱动常黑型液晶面板 15和常白型液晶面板 14。 其中, 仅驱动 常黑型液晶面板 15具体为设置常白型液晶面板的输出电压为零, 仅对常黑型液 晶面板输出电压。 同时驱动常黑型液晶面板 15和常白型液晶面板 14具体为同 时对常黑型液晶面板 15和常白型液晶面板 14输出电压。
具体而言, 请一并参阅图 2, 图 2是图 1所示的 3D显示系统的驱动装置的 结构示意图。如图 2所示,驱动装置 13进一步包括存储模块 131、判断模块 132 和控制模块 133。 其中, 存储模块 131预先存储开启时间 -亮度增幅比例的映射表, 该映射表 反映快门眼镜的不同的开启时间对应的亮度增幅比例。
本实施例中, 亮度增幅比例满足以下公式:
Λ SI-S2 Λ SI-S2
Α= ,. . Α=
SI 或者 S2 其中, SI为同时驱动常黑型液晶面板 15和常白型液晶面板 14的开启时间 的亮度值, S2为仅驱动常黑型液晶面板 15的开启时间的亮度值。 其中, S1和 S2对应相同的开启时间, 亮度值为在开启时间内通过快门眼镜 12 的光线的总 和。
请一并参阅图 3, 图 3是本发明的开启时间与亮度关系的坐标示意图。如图
3所示, 横坐标表示开启时间 T, 纵坐标表示亮度, 其中当亮度值为 a时表明快 门目艮镜 12通过的光线最多。 本实施例中, 假设同时驱动常黑型液晶面板 15和 常白型液晶面板 14时,快门眼镜 12的反应时间均为 1ms, 而仅驱动常黑型液晶 面板 15时, 快门眼镜 12的反应时间分别为 1ms和 2ms。 那么在开启时间 T为
4ms时, 快门目艮镜 12在同时驱动常黑型液晶面板 15和常白型液晶面板 14时的 亮度值为图 3中 S1的面积值, 由图 3可得, 此时的 S1的值为:
Sl = ^—— 1 ~ = 3a
2 同理, 快门眼镜 12在仅驱动常黑型液晶面板 15时的亮度值为图 3中 S2的 面积值, 由图 3可得, 此时 S2的值为:
S2 _ (l + 4) * a _ 5a
2 2 SI—S2
因此, 若选用公式 A=~ ^"计算亮度增幅比例, 则当开启时间为 4ms时,
SI
快门目艮镜 12的亮度增幅比例为:
Figure imgf000007_0001
同理, 用同样的方法可以计算出当开启时间分别为 3ms、 5ms、 6ms、 7ms 丄 丄 J_ J_ J_ 以及 8ms时, 快门眼镜 12的亮度增幅比例分别为 、 8 , 10、 以及 以此 类推。 则本实施例的开启时间-亮度增幅比例的映射表如下表 1所示。 表 1: 开启时间-亮度增幅比例的映射表
Figure imgf000007_0003
SI—S2
本实施例中,若选用公式 A=^~计算亮度增幅比例,则当开启时间为 4ms 时, 快门目艮镜 12的亮度增幅比例为
Figure imgf000007_0002
同理, 用同样的方法可以计算出当开启时间分别为 3ms、 5ms、 6ms、 7ms 以及 8ms时, 快门目艮镜 12的亮度增幅比例分别为 1、 丄、 丄、 丄以及丄, 以此
3 7 9 11 13 类推。 则本实施例的开启时间-亮度增幅比例的映射表也可如下表 2所示。
表 2: 开启时间-亮度增幅比例的映射表
Figure imgf000007_0004
由表 1和表 2可知, 亮度增幅比例 A的值随着开启时间 T的增长而减小。 值得注意的是, 当开启时间小于 3ms时, 开启时间小于仅驱动常黑型液晶 面板 15的反应时间, 因此, 此时选择同时驱动常黑型液晶面板 15和常白型液 晶面板 14的驱动方式。 表 1和表 2为开发人员在制作快门眼镜 12时根据快门 眼镜 12的特性来设置的。 不同的快门眼镜 12, 其常黑型液晶面板和常白型液晶 面板的反应时间也不一样, 因此, 表 1和表 2的映射关系也不一样。 本发明对 此不作限制。
本实施例中, 控制模块 133根据开启时间查询映射表, 以确定开启时间对 应的亮度增幅比例并将该亮度增幅比例发送到判断模块 132。判断模块 132预设 一阈值, 并判断开启时间对应的亮度增幅比例是否小于该阈值。 当判断的结果 为是时, 控制模块 133仅驱动常黑型液晶面板 15 , 当判断的结果为否时, 控制 模块 133同时驱动常黑型液晶面板 15和常白型液晶面板 14。
值得注意的是, 本发明的阈值的大小由用户定义。 本实施例中, 优选定义 A=10%-20%为阈值的取值范围。例如在如上表 1中, 若用户定义阈值大小为 1/9 时, 那么当显示装置 11控制快门目艮镜 12的开启时间 T小于 6ms时, 其对应的 亮度增幅比例均大于阈值 1/9, 则控制模块 133同时驱动常黑型液晶面板 15和 常白型液晶面板 14;当显示装置 11控制快门眼镜 12的开启时间 T大于 6ms时, 其对应的亮度增幅比例均小于阈值 1/9, 则控制模块 133仅驱动常黑型液晶面板 15。
在实际应用中, 用户根据快门目艮镜 12的特性, 如常黑型液晶面板 15和常 白型液晶面板 14的反应时间等因素来定义阈值的大小, 本发明在此不作限制。
本实施例中, 常黑型液晶面板 15和常白型液晶面板 14的反应时间越快, 在相同的开启时间内, 快门目艮镜 12的亮度增幅比例越小。 因此, 使用该亮度增 幅比例较小的快门眼镜 12时, 其阈值即可以设置得较小。 相应的, 如果使用亮 度增幅比例较大的快门眼镜 12时, 其阈值就要相应的设置得较大。
因此, 本发明能够根据快门眼镜的开启时间对应的亮度增幅比例选择仅驱 动常黑型液晶面板或者同时驱动常黑型液晶面板和常白型液晶面板的驱动方 式, 因此, 本发明的快门目艮镜能够适合不同的 3D显示系统, 增加了快门眼镜的 共用性。 另外, 当快门目艮镜的亮度增幅比例小于阈值时, 本发明的快门目艮镜仅 驱动常黑型液晶面板, 因此节省了能耗, 从而增长了快门眼镜的使用时间。
本发明更提供了一种 3D显示系统的驱动方法, 该 3D显示系统包括快门眼 镜和显示装置, 其中, 快门目艮镜包括驱动装置以及层叠设置的常白型液晶面板 和常黑型液晶面板。 具体请参阅图 4, 图 4是本发明实施例的 3D显示系统的驱 动方法的流程图。 如图 4所示, 3D显示系统的驱动方法包括以下步骤:
步骤 S41:显示装置向快门眼镜提供显示画面,并控制快门眼镜的开启时间。 步骤 S42: 驱动装置根据开启时间查询开启时间对应的亮度增幅比例, 并根 据亮度增幅比例选择其驱动方式, 驱动方式为仅驱动常黑型液晶面板或者同时 驱动常黑型液晶面板和常白型液晶面板。
其中,步骤 S42中的驱动装置还包括存储开启时间 -亮度增幅比例的映射表、 预设阈值并比较判断的步骤, 具体请参阅图 5 , 图 5是本发明的 3D显示系统中 的驱动装置的具体的驱动方法的流程图。 如图 5所示, 图 4所示的步骤 S42包 括以下步骤:
步骤 S421 : 预先存储开启时间 -亮度增幅比例的映射表, 该映射表反映快门 眼镜的不同的开启时间对应的亮度增幅比例。
在步骤 S421中, 亮度增幅比例满足以下公式:
Λ SI-S2 Λ SI-S2
SI 或者 其中, SI为同时驱动黑型液晶面板和常白型液晶面板的开启时间的亮度值, S2为驱动常黑型液晶面板的开启时间的亮度值。 其中, S1和 S2对应相同的开 启时间, 亮度值为在开启时间内通过快门眼镜的光线的总和。
具体的开启时间-亮度增幅比例的映射表的建立如前文所述,在此不再赘述。 步骤 S422: 预设一阈值, 并判断开启时间对应的亮度增幅比例的值是否小 于阈值。
其中, 在步骤 S422前首先根据开启时间查询映射表, 以确定开启时间对应 的亮度增幅比例。
在步骤 S422中, 当判断的结果为是时, 跳转到步骤 S423 , 当判断的结果为 否时, 跳转到步骤 S424。
值得注意的是, 本发明的阈值的大小由用户定义。 本实施例中, 优选定义 A=10%-20%为阈值的取值范围。例如在如上表 1中, 若用户定义阈值大小为 1/9 时, 那么当显示装置控制快门目艮镜的开启时间小于 6ms时, 其对应的亮度增幅 比例均大于阈值 1/9, 则同时驱动常黑型液晶面板和常白型液晶面板; 当显示装 置控制快门眼镜的开启时间 T大于 6ms时, 其对应的亮度增幅比例均小于阈值 1/9, 则仅驱动常黑型液晶面板。
在实际应用中, 用户根据快门眼镜的特性, 如常黑型液晶面板和常白型液 晶面板的反应时间等因素来定义阈值的大小, 本发明在此不作限制。
本实施例中, 常黑型液晶面板和常白型液晶面板的反应时间越快, 在相同 的开启时间内, 快门眼镜的亮度增幅比例越小。 因此, 使用该亮度增幅比例较 小的快门眼镜时, 其阈值即可以设置得较小。 相应的, 如果使用亮度增幅比例 较大的快门目艮镜时, 其阈值就要相应的设置得较大
步骤 S423: 仅驱动常黑型液晶面板。
在步骤 S423中, 仅驱动常黑型液晶面板具体为设置常白型液晶面板的电压 为零, 仅对常黑型液晶面板输出电压。
步骤 S424: 同时驱动常黑型液晶面板和常白型液晶面板。
在步骤 S424中, 同时驱动常黑型液晶面板和常白型液晶面板具体为同时对 常黑型液晶面板和常白型液晶面板输出电压。
综上所述,本发明的 3D显示系统通过快门目艮镜的驱动装置判断快门目艮镜的 开启时间, 然后根据开启时间查询开启时间对应的亮度增幅比例, 并将该亮度 增幅比例与预设的阈值进行比较, 当亮度增幅比例小于阈值时, 快门眼镜仅驱 动常黑型液晶面板; 当亮度增幅比例大于阈值时, 快门眼镜同时驱动常黑型液 晶面板和常白型液晶面板。 因此, 本发明的快门眼镜能够适合不同的 3D显示系 统, 提高了快门眼镜的共用性。 并且, 本发明仅驱动常黑型液晶面板的驱动方 法能够节省能耗, 从而增长了快门眼镜的使用时间。
以上所述仅为本发明的实施方式, 并非因此限制本发明的专利范围, 凡是 利用本发明说明书及附图内容所作的等效结构或等效流程变换, 或直接或间接 运用在其他相关的技术领域, 均同理包括在本发明的专利保护范围内。
