立体图像显示方法以及相应的立体图像显示装置
【技术领域】
本发明涉及一种立体图像显示方法以及相应的立体图像显示装置, 特别是 涉及一种利用主动式快门眼镜来观看立体图像的立体图像显示方法以及相应的 立体图像显示装置。
【背景技术】
随着科技的发展, 立体 (或 3D)图像显示装置由于能够使观看者观看到逼真 的图像, 因此获得消费者的青睐。 目前, 立体图像显示装置主要分为眼镜型立 体显示装置以及非眼镜型立体显示装置。 其中, 目艮镜型立体显示装置主要是在 显示面板上分别显示左眼图像以及右眼图像, 然后通过偏光眼镜或者快门眼镜 来分别接收左眼图像以及右眼图像, 从而实现立体图像。 而非眼镜型立体显示 装置通常是将视差屏障这样的光学板设置在显示面板上, 利用视差屏障来分离 左右视差图像。
对于使用快门眼镜的立体图像显示装置来说, 其在奇数帧时段期间, 快门 眼镜的左眼快门打开, 从而在显示面板上顺序地扫描左眼图像数据; 而在偶数 帧时段期间, 快门眼镜的右眼快门打开, 从而在显示面板上顺序地扫描右眼图 像数据, 则使用者可利用主动式快门目艮镜而观看到立体图像。
现有的立体图像显示装置一般以液晶显示面板作为其显示面板来显示左眼 图像数据以及右眼图像数据, 即以普通的液晶显示面板作为显示面板来显示图 像数据。 当液晶显示器以直流电压来操控液晶层时, 其电极上容易累积电荷, 造成电压残留, 且其电容也不易充电, 影响立体图像显示装置的显示效果。 因 此, 为了克服上述缺陷, 目前已经开发出利用交流电压来进行驱动的液晶显示 面板。
图 1 为现有的以交流电压来进行驱动的液晶显示面板的工作原理示意图。 如图 1 所示, 液晶显示面板中的每个像素所对应的像素电位可划分成正半周以
及负半周, 当位于正半周时, 像素电位高于公共电位 Vcom, 即像素电位具有正 极性; 当位于负半周时,像素电位低于公共电位 Vcom, 即像素电位具有负极性; 而液晶分子上所感受到的电压差为像素电位与公共电位 Vcom之间的压差。 因 此可调整公共电位 Vcom的值使得公共电位 Vcom位于正半周的像素电位与负半 周的像素电位的正中间, 从而使得在正、 负半周时, 液晶分子所感受到的电压 差一致。 此外, 由于液晶显示器釆用极性交替变化的像素电位来驱动此像素, 因此其可避免电荷的累积。
但是, 受制程均匀度的影响, 液晶显示面板的不同位置的像素在制程时都 会有些许的差异, 从而造成各个像素的正、 负半周的中心位准都不一样。 而在 进行调整时, 只能以某一个像素的中心位准为基准来进行调整以产生基准的公 共电位。 因此势必会有其他位置的像素的中心位准与基准的公共电位不一致的 情形, 则会产生某些像素所对应的液晶分子感受到的电压差在正、 负半周不一 致的情形, 从而产生闪烁现象, 影响显示效果。

所示, 本发明的立体图像显示装置 200包括显示面板 210、 背光模组 220以及快 门眼镜 230。 其中, 显示面板 210可为液晶显示面板, 用以时序地写入左眼图像 数据以及右眼图像数据, 其可划分为多个显示区域, 例如 N个显示区域, 其中 N为偶数。 背光模组 220可对应地划分为 N个光源区域, 其时序地开启和关闭 这些光源区域, 从而依次扫描左眼图像数据和右眼图像数据。 快门眼镜 230 交 替地开启和关闭左眼快门和右眼快门, 以在左眼快门开启时接收左眼图像数据, 而在右眼快门开启时接收右眼图像数据。
此外, 立体图像显示装置 200还包括显示面板驱动电路 240、 背光模组驱动 电路 250、 快门眼镜驱动电路 260以及控制器 270。 控制器 270分别电性连接显 示面板驱动电路 240、 背光模组驱动电路 250以及快门目艮镜驱动电路 260, 以分 别控制这些驱动电路。 其中显示面板驱动电路 240用于驱动显示面板 210以写 入图像数据至显示面板 210 , 其可包括栅极驱动电路以及源极驱动电路。 背光模 组驱动电路 250用于驱动背光模组 220, 以时序地开启和关闭背光模组 220的这 些光源区域。 而快门目艮镜驱动电路 260用于驱动快门目艮镜 230, 以交替地开启和 关闭其左眼快门和右眼快门。
图 3〜图 10为图 2所示的立体图像显示装置显示立体图像的工作原理示意 图。 如图 3所示, 时序地将第一极性的图像数据依次写入显示面板 210的 N个 显示区域 211 中。 在本实施例中, 以 8个显示区域 211为例来介绍本发明, 第 一极性可为正极性。 当正极性的图像数据写入第 (N/2+1)显示区域时, 开始时序 地开启背光模组 220的 N个光源区域 221 , 从而依次地扫描对应显示区域 211 的正极性的图像数据。
在本实施例中, 即是当正极性的图像数据写入第 5 显示区域时, 开启第 1 光源区域。 由于第 1光源区域所对应的第 1显示区域已经写入正极性的图像数 据, 因此当第 1光源区域开启时, 则第 1显示区域受第 1光源区域发出的光线 照射, 从而显示相应的图像。 也就是说, 第 1 光源区域的开启, 则会扫描第 1 显示区域中的正极性的图像数据。 此时, 快门眼镜 230 中的左眼快门开启, 而
右眼快门关闭, 因此第 1 显示区域中的正极性的图像数据会被使用者的左眼所 接收。
然后, 继续依次地将正极性的图像数据写入其余的显示区域, 并依次地开 启光源区域。 如图 4所示, 当将正极性的图像数据写入第 8显示区域时, 此时 会开启第 4光源区域, 以扫描对应的第 4显示区域所写入的正极性的图像数据。 而快门眼镜 230会一直维持上述状态, 从而依次地接收第 2~4显示区域中的正 极性的图像数据。
接着, 如图 5所示, 当第 (N/2+1)光源区域开启时, 开始时序地将第二极性 的图像数据依次地写入显示面板 210 的这些显示区域。 在本实施例中, 当第 5 光源区域开启时, 第二极性的图像数据写入第 1 显示区域, 而第二极性可为负 极性, 其与第一极性相反。 此时, 由于第 1 显示区域中写入的正极性的图像数 据已经被扫描, 且已经被使用者的左眼所接收, 因此在此时将负极性的图像数 据写入第 1显示区域, 并不会影响使用者的观看。
然后, 继续依次地开启这些光源区域, 并依次地将负极性的图像数据写入 这些显示区域。 如图 6所示, 当第 8光源区域开启时, 其扫描对应的第 8显示 区域的正极性的图像数据, 而快门眼镜 230会一直维持上述状态, 从而依次地 接收第 6~8显示区域中的正极性的图像数据。 而此时, 负极性的图像数据也依 次地写入第 2~4显示区域中。 因此, 第 1~8光源区域依次开启, 则正极性的图 像数据会依次被使用者的左眼所接收, 从而接收完正极性的图像数据。 由于正 极性的图像数据是依次被使用者的左眼所接收, 因此正极性的图像数据作为左 眼图像数据。
然后, 当 N个光源区域依次开启完毕后, 返回重复地依次开启这 N个光源 区域。 如图 7所示, 返回重复开启第 1光源区域以扫描第 1显示区域, 此时第 1 显示区域中所写入的图像数据为负极性的图像数据。 因此第 1 光源区域的重复 开启会扫描此时第 1 显示区域中的负极性的图像数据。 此外, 在此时, 快门眼 镜 230的左眼快门关闭, 而右眼快门开启, 从而接收第 1显示区域中的负极性
的图像数据。
最后, 继续依次地将负极性以及正极性的图像数据写入显示区域, 并依次 地开启光源区域, 直至第 8显示区域开启完毕, 则使用者的右目艮会依次地接收 第 1~8显示区域的负极性的图像数据以作为右眼图像数据, 并将另一帧的正极 性的图像数据依次写入部分的显示区域,如图 8~10所示。反复地执行上述步骤, 从而依次地在显示面板 210 上显示左眼图像数据和右眼图像数据, 并利用快门 眼镜 230而使使用着依次地接收左眼图像数据和右眼图像数据。
根据上述立体图像显示装置 200的工作原理可知, 快门眼镜 230的左眼快 门开启时, 接收到的左眼图像数据总是正极性的图像数据; 而右眼快门开启时, 接收到的右眼图像数据总是负极性的图像数据。 因此, 即使某些位置的像素的 中心位准与作为基准的公共电位不一致, 由于使用者的左眼总是接收同一极性 的图像数据, 而其右眼也总是接收另一同一极性的图像数据, 因此使用者在观 看时, 并不会察觉到像素的中心位准和作为基准的公共电位不一致的现象, 即 并不会察觉到闪烁现象, 因此其并不会影响立体图像显示装置 200的显示效果。
此外, 根据上述立体图像显示装置 200 的工作原理可知, 依次开启光源区 域以扫描图像数据的期间落后于依次写入一帧图像数据至显示区域的期间, 如 果将依次写入一帧图像数据至显示区域的期间定义为一帧时段, 则依次开启光 源区域以扫描图像数据的起始点落后于依次写入一帧图像数据至显示区域的起 始点。
综上所述, 本发明的立体图像显示装置以及立体图像显示方法中, 使用者 的左眼总是接收同一极性的图像数据, 而其右眼也总是接收另一同一极性的图 像数据, 因此使用者在观看时, 并不会察觉到闪烁现象, 其并不会影响其显示 效果。
以上所述仅为本发明的实施例, 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。
