Description

液晶立体显示系统及驱动方法
技术领域
本发明是有关于一种液晶立体显示系统， 特别是有关于一种使用快门眼镜的立体显示 系统。 背景技术
显示器是人与科技最重要的接口。 显示画面的技术朝高分辨率、 高画质、 大尺寸演进。 下一个显示技术将是由平面影像显示转变成立体影像的显示， 以满足人类视觉中最重要的 立体视觉。
裸眼式立体显示器 (Autostereoscopic display)是透过从不同视角的多个图像分别进 入左右双眼， 不需借助特殊的眼镜， 即可看到立体图像。 目前裸眼式立体影像显示器可分 为时间多任务式（Temporal multiplexed)及空间多任务式（Spatial multiplexed) , 这两种 方式都存在同一个问题， 一旦眼晴的位置偏离指定位置， 就没有了立体显示效果，
另一种立体显示器是搭配快门眼镜的使用。 当立体显示器在播放影像时， 会把影像分 为左眼画面和右眼画面。 当显示器设定播放左眼画面是给左眼观看时， 便会利用快门眼镜 将右眼遮住， 保证只有左眼看到。 之后再播放右眼画面给右眼观看时， 再利用快门眼镜将 左眼遮住， 保证只有右眼看到， 如此左右交替便能看到立体影像。 然而， 这种立体显示器 的缺体是， 在显示左眼画面和右眼画面的转换过程时， 观察者常常会看到残影的现象。 具 体来说， 此种残影的现象是指当一使用者透过快门眼镜观看一显示器上的立体画面时， 在 打开快门眼镜的左眼快门时， 显示器上的右眼画面还未完全消失， 因此显示器的观察者会 看到右眼影像画面的状况； 或指当快门眼镜的右眼快门被打开时， 显示器的左眼影像画面 还未完全消失。 而观察者会看到左眼影像画面的状况， 这种情况在显示器为液晶显示器时 较容易发生。
在先前技术中， 是以使用快速响应液晶材料的方式， 来避免上述残影现象发生。 请参 照图 2, 图 2为先前搭配快门眼镜及发光单元的时序图。 如图 2所示， 当时序控制单元发出 第一信号时， 发光单元就呈现开启状态， 并且之后不为任何装置所控制， 为一恒定的开启 状态。 第一信号的发出也表示显示器显示左眼画面， 此时左眼镜片及右眼镜片都呈现关闭 状态， 且在第一信号发出后， 经过一段时间， 直到左眼画面稳定后， 左眼镜片才开启而右 眼镜片还保持关闭状态， 直到时序控制单元发出第二信号， 当第二信号发出后， 表示显示 器显示右眼画面， 左眼镜片立刻变为关闭状态， 经过一段时间， 直到左眼画面稳定后， 右 眼镜片才开启而右眼镜片还保持关闭状态， 直到时序控制单元发出第三信号， 当第三信号 发出后， 表示显示器显示左眼画面， 右眼镜片立刻变为关闭状态， 直到左眼画面稳定后， 左眼镜片才开启而右眼镜片还保持关闭状态。 如此， 左眼镜片及右眼镜片配合时序控制单 元的信号， 交互重复开启及关闭的动作， 而发光源模组为一恒定开启的状态。 图中的左眼 镜片及右眼镜片时序图中的虚线表示实际开启与关闭的示意过程。
上述的技术可以减少残影的现像， 但这种方式有一个缺点， 因为通常立体画面切换的 频率很快， 需要在 120Hz 以上， 才不会有因画面切换的因素产生的不适感， 因此同时也会 要求主动快门眼镜的响应速度也要很快， 不然左右眼看到的画面会混淆。 为了达到快速响 应的效果， 通常主动快门眼镜的镜片里面要用到快速响应的液晶材料， 而上述技术所要求 的眼镜响应速度要更快， 这样就会导致液晶眼镜的成本很高。
因此本发明通过改变发光源模组和眼镜的驱动时序， 在主动快门眼镜的制作过程中， 不需使用快速响应的液晶材料， 使得主动快门眼镜的成本降低。 发明内容
为解决上述问是， 本发明提出一种液晶立体显示系统的驱动方法， 藉由控制背光模组 及立体眼镜的时序， 达到减少制作成本以及更佳的立体显示效果。
本发明为解决上述技术问题采用的技术方案为， 该液晶立体显示系统包括一背光模组、 一图像显示装置与一快门眼镜装置， 该图像显示装置用以显示一右眼影像以及一左眼影像， 该快门眼镜装置包含一左眼镜片与一右眼镜片， 更包括， 接收一时序控制信号； 依据该时 序控制信号， 关闭该背光模组， 并且在下一个时序控制信号产生前打开背光模组； 以及依 据时序控制信号， 显示该左眼影像时， 打开该左眼镜片及关闭该右眼镜片。
为解决上述问题， 本发明提出一种液晶立体显示系统， 达到减少制作成本以及更佳的 立体显示效果。
本发明为解决上述技术问题采用的技术方案包括， 提出一种液晶立体显示系统， 包括 一图像显示装置， 用以根据时序控制信号依序显示一右眼影像以及一左眼影像； 一快门眼 镜装置， 具有一右眼镜片以及一左眼镜片， 该右眼镜片根据时序控制信号呈现打开状态或 关闭状态， 左眼镜片根据时序控制信号呈现打开状态或关闭状态； 以及一背光模组， 以提 供一光源给图像显示装置， 其中背光模组根据时序控制信号而进行关闭动作， 且该背光模 组在下一个时序控制信号产生前会进行开启动作。
本发明的特点在于， 控制快门眼镜装置的左右眼镜片的开启时间及控制发光模组的开 启和关闭时间， 减少残影的现像， 如此在液晶立体显示系统的制作过程中不必使用快速响 应的液晶材料， 使得液晶立体显示系统的成本降低 附图说明
图 1为最佳实施例的液晶立体显示系统的电路系统示意图。
图 2为现有技术的电路装置时序图。
图 3为本发明最佳实施例的电路装置时序图。 具体实施方式
以下结合附图所示的最佳实施例作进一步详述。
图 1 为最佳实施例的液晶立体显示系统的电路系统示意图。 本实施例的液晶立体显示 系统包括一显示器 100以及一立体眼镜 200所组成。
当使用者使用液晶立体显示系统时， 使用者需佩带该立体眼镜 200观看该显示器 100 所显示的图像。
下面分别说明该显示器 100及该立体眼镜 200的电路系统及动作。
首先说明显示器 100， 该显示器 100包括一时序控制单元 120、 背光模组 110以及一图 像显示装置 130等组成， 其中背光模组又包括驱动电路 111及发光单元 113。
时序控制单元 120发出时序控制信号给该背光模组 110、该图像显示装置 130及该立体 眼镜 200， 让每个装置都有一个可以依循的信号。
该时序控制单元 120以电性连接方式连接该背光模组 110以及该图像显示装置 130，方 便以电子电路的方式传送信号。 该图像显示装置 130从该时序控制单元 120收到的时序控 制信号定义为影像同步信号 123，该图像显示装置 130就依据该影像同步信号 123将左眼影 像及右眼影像依序的播放出来。
该背光模组 110主要提供一光源给该图像显示装置 130，其中该驱动电路 111作为接收 该时序控制单元 120发出的时序控制信号的装置， 在此定义此时序控制信号为同步控制信 号 121。 该驱动电路 111依据该同步控制信号 121判断出何时点亮该发光单元 113、 何时关 闭该发光单元 113以及控制该发光单元 113的亮度，并发出一驱动信号 112给发光单元 113。
背光模组中的发光单元 113以电性连接该驱动电路 111，方便该驱动电路 111以电子电 路的方式传送驱动信号 112， 该发光单元 113依据该驱动信号 112呈现开启或关闭状态， 当 开启时， 使用者能看到图像显示装置 130显示的左眼影像或右眼影像， 当关闭时， 虽然该 图像显示装置 130有显示左眼图像或右眼图像， 但少了该发光单元的光， 导致使用者将看 不到任何图像。
使用者须再借由配带该立体眼镜 200， 观看显示器， 就可以看到立体影像， 接下来说明 该立体眼镜 200的电路结构。
该立体眼镜 200包括一信号接收电路 210、 一控制单元 220、 一左右眼切换开关 230、 一电源供应装置 250， 一左眼镜片 241及一右眼镜 242等组成， 且各元件都以电性连接方式 连接。
使用者在使用该立体眼镜 200时， 须启动该电源供应装置 250， 该电源供应装置 250以 电性连接分式连接不同电路、 单元、 开关及构造， 并给予不同的能量予以启动， 当信号接 收电路 210被启动时， 该信号接收电路 210就会从时序控制单元 120收到时序控制信号， 因为该时序控制单元 120以红外线方式传送信号给信号接收电路 210，因此定义此信号为红 外线信号 122。
当该信号接收电路 210收到红外线信号 122时， 会依据该红外线信号 122的内容转成 电子信号，给下一级的该控制单元 220。该控制单元 220会去判断信号的正确与否及信号的 内容， 确定信号的内容后会再送出一信号给该左右眼镜片切换开关 230。
该左右眼切换开关 230会依据从控制单元 220收到的信号， 控制下一级的左眼镜片及 右眼镜片的开启或关闭。
其中时序控制单元 120、 驱动电路 111、 控制单元 220及左右眼镜片切换开关 230可为 晶片组（Chip Set) , 处理器（Processor 如 CPU、 MPU)、 其它辅助电路、 运算程序 (Operation Software)、 韧体（Firmware)或相关模组、 元件、 软件所组成， 但不以 此为限。
其中发光单元 110可为， 发光二极管（Light-emitting diodes)、 灯管、 其它辅助电 路或其它可发光的元件所组成， 但不以此为限。
其中图像显示装置 130可为穿透式液晶面板、 半穿反式液晶面板或和其它辅助电路 所组成， 但不以此为限。
其中该左眼镜片 241及该右眼镜片 242由具有透明电极的液晶面板和其它辅助电路所 组成， 但不以此为限。
其中该电源应装置， 可为内置电源型或外接电源型， 内置电源型可为一般电池、 锂电 池、 充电电池、 太阳能电池或其它辅助电路所组成。
图 3为本发明最佳实施例的电路驱动时序图， 当时序控制单元发出第 1信号时， 表示 图像显示装置要显示左眼画面， 在此同时该左眼镜片立刻呈现开启状态， 而右眼镜片为关 闭状态， 但该左眼镜片因为液晶材料的因素， 要经过一段稳定时间才能完全呈现开启状态， 当该左眼镜片过了稳定时间呈现完全开启状态后， 发光单元才会开启， 直到该时序控制单 元发出第 2讯号， 该发光单元才呈现关闭状态， 图中该左眼镜片时序图的虚线即表示实际 开启与关闭的示意过程。
当该时序控制单元发出第 2信号时， 表示图像显示装置要显示右眼画面， 在此同时， 该发光单元和该左眼镜片立刻呈现关闭状态， 而该右眼镜片立刻呈现开启状态， 但该右眼 镜片因为液晶材料的因素， 要经过一段稳定时间才能完全呈现开启状态， 当该右眼镜片过 了稳定时间呈现开启状态后该发光单元才开启， 直到该时序控制单元发出第 3讯号， 该发 光单元才呈现关闭状态， 图中右眼镜片时序图的虚线即表示实际开启与关闭的示过程。 每 当该时序控制单元发出一信号时， 该发光单元、 该左眼镜片及该右眼镜片， 就会依序的开 启或关闭。
以上， 仅为本发明的较佳实施例， 意在进一步说明本发明， 而非对其进行限定。 凡根 据上述文字和附图所公开的内容进行的简单的替换， 都在本专利的权利保护范围之列。
