三是整机成本低。 和其他 3D 显示方案相比， 本发明实施例不需要昂贵的 光学屏幕或者光学膜， 工艺筒单， 大大降低了整机成本。 附图说明
为了更清楚地说明本发明实施例的技术方案，下面对实施例所需要使用的 附图作筒单地介绍，显而易见地， 下面描述中的附图仅仅是本发明的一些实施 例， 对于本领域普通技术人员来讲， 在不付出创造性劳动的前提下， 还可以根 据这些附图获得其他的附图。
图 1是液晶显示的基本原理示意图；
图 2是时分眼镜型 3D显示技术的原理图；
图 3是液晶屏幕发出的左右眼图像信号示意图；
图 4是根据本发明实施例的一种用于 3D显示的方法流程图；

图 9是根据本发明实施例的一种用于 3D显示的电视机逻辑结构示意图； 图 10是根据本发明实施例的另一种用于 3D显示的电视机逻辑结构示意 图。 具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是 全部的实施例。基于本发明中的实施例， 本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
图 1是液晶显示的基本原理示意图。每一帧图像由若干行组成， 且以行为 单位依次驱动。图 la和图 lb以 1920*1080的屏幕为例说明了液晶显示驱动原 理。 液晶具有亮度维持特性， 即当第 n行被驱动后， 会维持该亮度， 直到有新 的驱动信号驱动。 所以， 在显示相邻的两帧图像时， 比如第 n帧和第 n+1帧， 在第 n+1帧图像中会有部分内容是第 n帧的。 在显示 3D内容时， 由于相邻两 帧之间图像内容差别很小，且需要分别送给左眼和右眼， 这种维持特性会引起 两眼内容串扰， 不能产生立体感觉。
本发明采用时分法实现 3D图像的显示， 其属于眼镜型中的一种， 目艮镜型 中的时分法是将左右眼图像按照时序轮流显示并传输到眼睛中， 参见图 2, 其 是时分眼镜型 3D显示技术的原理图， 液晶屏幕顺序发出左右眼图像信号， 并 发出同步信号， 光阀眼镜接收到同步信号后控制左右眼镜片的开关，使用户的 左右眼分别接受左右眼图像信号。
图 3所示是液晶屏幕发出的左右眼图像信号示意图， 可知， 左右眼图像信 号是交替时序发出的。
实施例一： 倍频时分 3D图像信号， 控制 LED背光
实施例一所提供的用于 3D图像显示的方法， 包括： 接收 3D图像信号， 所述 3D图像信号包括连续的一帧左眼信号一帧右眼信号； 对所述 3D图像信 号倍频处理， 获得连续的 n帧左眼信号和连续的 n帧右眼信号， 所述 n为倍频 的倍数， 且大于等于 2; LED驱动信号驱动显示所述连续的 n帧左眼信号和连 续的 n帧右眼信号；
所述连续的 n帧左眼信号中第一帧左眼信号所对应的 LED驱动信号为关 闭， 第 n帧左眼信号所对应的 LED驱动信号为打开， 所述连续的 n帧右眼信 号中第一帧右眼信号所对应的 LED驱动信号为关闭， 所述第 n帧右眼信号所 对应的 LED驱动信号为打开。
其中， 所述连续的 n帧左眼信号中的第 2至第 n-1帧所对应的 LED驱动 信号为打开或关闭； 所述连续的 n帧右眼信号中的第 2至第 n-1 帧所对应的 LED驱动信号为打开或关闭。 也就是说， 对连续的 n帧左眼信号和右眼信号 内的中间帧所对应的 LED 驱动信号没有严格的限制， 可根据实际需要设置 LED驱动信号为打开或关闭。
再有， 还可以从所述 3D图像信号中提取出同步控制信号； 根据所述同步 控制信号控制所述 LED驱动信号以及控制向观看所述 3D图像信号的眼镜发 送镜片开闭信号，控制打开右眼镜片关闭左眼镜片，或关闭右眼镜片打开左眼 镜片； 具体的， 当控制打开右目艮镜片关闭左目艮镜片时， LED 驱动信号驱动显 示所述连续的 n 帧右眼图像信号； 当控制关闭右目艮镜片打开左目艮镜片， LED 驱动信号驱动显示所述连续的 n帧左眼图像信号。
上述向眼镜发送镜片开闭信号的方式包括： 红外、 射频或蓝牙的方式。 下面以两倍频为例， 具体说明实施例一的实现过程。
参见图 4, 其是根据本发明实施例的一种用于 3D显示的方法流程图， 所 述流程具体包括：
步骤 401 ,电视机中的主板将接收到的图像信号处理为时分 3D图像信号， 对所述时分 3D图像信号进行倍频处理， 生成 3D倍频图像信号；
其中， 上述每帧时分 3D图像信号对应两帧图像内容相同的 3D倍频图像 信号； 所述时分 3D图像信号包括左眼图像信号和右眼图像信号；
其中， 电视机中的主板所接收到的图像信号可以是各种格式的 3D图像信 号；
步骤 402, 电视机中的主板将所述 3D倍频图像信号转换为低电压差分信 号 （ LVDS )格式后送入液晶面板驱动板 ( T_CON ) , 驱动液晶面板时分显示 左眼图像信号和右眼图像信号；
步骤 403 , 电视机中的主板从所述时分 3D图像信号中提取出同步控制信 号， 将所述同步控制信号发送给 LED背光驱动控制模块和开关眼镜模块； 步骤 404, LED背光驱动控制模块和开关眼镜模块分别根据所述同步控制 信号进行控制， 具体的：
所述 LED背光驱动控制模块根据所述同步控制信号控制两帧图像内容相 同的 3D倍频图像信号中的一帧所对应的 LED驱动信号为关闭， 另一帧对应 的 LED驱动信号为打开；
所述开关眼镜模块根据所述同步控制信号向眼镜发送镜片开闭信号，控制 打开右眼镜片关闭左眼镜片， 或关闭右眼镜片打开左眼镜片； 其中， 当控制打开右眼镜片关闭左眼镜片时，驱动液晶面板显示两帧相同 的右眼图像信号； 当控制关闭右目艮镜片打开左眼镜片，驱动液晶面板显示两帧 相同的左眼图像信号。
需要说明的是， 所述开关眼镜模块根据所述同步控制信号可以通过红外、 射频或蓝牙等方式向眼镜发送镜片开闭信号。
下面从时序的角度对实施例一再做说明。
参见图 5 , 其是根据本发明实施例一的时分 3D图像信号、 LED驱动信号 以及左右眼图像时序图示。 图中， L和 R分别代表左右眼图像信号。
时分 3D图像信号 （如 Rn、 Ln等） 经倍频后处理后形成如图 5所示的倍 频 3D图像信号 (如 Rn"、 Rn' Ln"和 Ln，等），其中， Ln"和 Ln，内容相同， Ln+1" 和 Ln+Γ内容相同， Rn"和 Rn，内容相同， Rn+l"和 Rn+Γ内容相同。 对于 LED 驱动信号， 在第 Rn"、 Ln"、 Rn+1"、 Ln+1"帧时打开， 在第 Rn，、 Ln，、 Rn+1，、 Ln+1，帧时关闭。 左眼接收到的信号中， 前一部分是图像内容， 后一部分由于 LED关闭， 为暗场。 右眼也是如此。
在电视机一端， LED背光控制方法是这样的： 由来自时分 3D图像信号的 同步控制信号即帧同步信号锁定 LED背光的时序控制，使 LED背光在显示第 Ln"帧、 第 Rn"帧期间开启， 而在第 Ln，帧、 第 Rn，帧期间关闭。
而在眼镜一端， 当第 Rn"帧和第 Rn，帧图像显示时， 在开关眼镜模块的控 制下右目艮镜片被打开， 左眼镜片被关闭； 当第 Ln"和 Ln，帧图像显示时， 在开 关眼镜模块的控制下左目艮镜片被打开， 右眼镜片关闭。 这样， 通过 LED背光 的控制和眼镜的配合， 就可以实现左眼和右眼信号的分离， 并在大脑中形成立 体感觉。
应用本发明的实施例一提供的用于 3D显示的方法，和以往解决方案相比， 至少有以下突出优点：
一是解决了左右画面串扰问题。液晶显示的机理决定了在显示下一帧画面 时会有上一帧的残留存在， 这对于 3D显示来说是不允许的， 否则会存在左右 眼图像的串扰， 大大降低甚至无法实现 3D感觉。 而本发明实施例所提供的方 案可以解决此问题。 当有串扰的那一帧显示时， 虽说有画面内容， 但因此时背 光关闭而看到的只是一幅黑色画面， 不会引起串扰。
二是降低了背光源的能耗。 本发明实施例中在关闭 LED 光源期间， 能耗 几乎为零。 LED控制信号的占空比为 50%, 能耗节约接近 50%。
三是整机成本低。 和其他 3D 显示方案相比， 本发明实施例不需要昂贵的 光学屏幕或者光学膜， 工艺筒单， 大大降低了整机成本。 实施例二： 倍频时分 3D图像信号， 插入黑场
实施例二所提供的用于 3D图像显示的方法， 包括： 接收 3D图像信号， 所述 3D图像信号包括连续的一帧左眼信号一帧右眼信号； 在所述 3D图像信 号中插入黑场信号， 并且对所述 3D图像信号倍频处理， 生成包含黑场信号的 连续的 n帧左眼信号和连续的 n帧右目艮信号， 所述 n为倍频的倍数，且大于等 于 2; 其中， 所述连续的 n帧左眼信号中的第一帧为黑场信号， 第 n帧为非黑 场信号， 所述连续的 n帧右眼信号中的第一帧为黑场信号， 第 n帧为非黑场信 号； LED驱动信号驱动显示所述连续的 n帧左眼信号和连续的 n帧右眼信号。
其中，所述连续的 n帧左眼信号中的第 2至第 n-1帧所对应的图像信号为 黑场信号或非黑场信号； 所述连续的 n帧右眼信号中的第 2至第 n-1帧所对应 的图像信号为黑场信号或非黑场信号。也就是说，对连续的 n帧左眼信号和右 目艮信号内的中间帧是否为黑场信号没有严格的限制， 可根据实际需要设置。
再有， 还可以从所述 3D图像信号中提取出同步控制信号； 根据所述同步 控制信号控制所述 LED驱动信号以及控制向观看所述 3D图像信号的眼镜发 送镜片开闭信号，控制打开右眼镜片关闭左眼镜片，或关闭右眼镜片打开左眼 镜片； 具体的， 当控制打开右目艮镜片关闭左目艮镜片时， LED 驱动信号驱动显 示所述连续的 n 帧右眼图像信号； 当控制关闭右目艮镜片打开左目艮镜片， LED 驱动信号驱动显示所述连续的 n帧左眼图像信号。
上述方法还可以进一步包括： 根据所述同步控制信号， 控制所述连续的 n 帧左眼信号中黑场信号所对应的 LED驱动信号为关闭， 非黑场信号所对应的 LED驱动信号为打开；控制所述连续的 n帧右眼信号中黑场信号所对应的 LED 驱动信号为关闭， 非黑场信号所对应的 LED驱动信号为打开。
上述向眼镜发送镜片开闭信号的方式包括： 红外、 射频或蓝牙的方式。 下面以两倍频为例， 具体说明实施例二的实现过程。
参见图 6, 其是根据本发明实施例的另一种用于 3D显示的方法流程图， 所述流程具体包括： 步骤 601 ,电视机中的主板将接收到的图像信号处理为时分 3D图像信号， 在所述时分 3D图像信号中插入黑场信号，生成包含黑场的 3D倍频图像信号； 也就是说，此时的 3D倍频图像信号为"黑场信号 +左眼信号 +黑场信号 +右 眼信号，，；
其中， 所述时分 3D图像信号包括左眼图像信号和右眼图像信号； 步骤 602, 电视机中的主板将所述包括黑场信号的 3D倍频图像信号转换 为低电压差分信号格式后送入液晶面板驱动板，驱动液晶面板时分显示左眼图 像信号和右眼图像信号； 并且，
步骤 603 , 电视机中的主板从所述 3D图像信号中提取出同步控制信号， 将所述同步控制信号发送给开关眼镜模块；
步骤 604 , 开关眼镜模块根据所述同步控制信号向眼镜发送镜片开闭信 号， 控制打开右目艮镜片关闭左眼镜片， 或关闭右目艮镜片打开左眼镜片；
其中， 当控制打开右眼镜片关闭左眼镜片时，驱动液晶面板显示一帧黑场 信号和一帧右眼图像信号； 当控制关闭右眼镜片打开左眼镜片， 驱动液晶面板 显示一帧黑场信号和一帧左眼图像信号。
需要说明的是， 所述开关眼镜模块根据所述同步控制信号可以通过红外、 射频或蓝牙等方式向眼镜发送镜片开闭信号。
下面从时序的角度对实施例一再做说明。
参见图 7 , 其是根据本发明实施例二的时分 3D图像信号、 LED驱动信号 以及左右眼图像时序图示。 图中， L和 R分别代表左右眼图像信号。
时分 3D图像信号 （如 Rn、 Ln等）经插入了黑场信号处理后形成如图 7 所示的倍频 3D图像信号 (如 Rn"、 Rn' Ln"和 Ln，等）， 因而， Ln"和 Ln内容相 同， Ln'为黑场信号； Ln+1"和 Ln+1内容相同， Ln+Γ 为黑场信号； Rn"和 Rn 内容相同， Rn' 为黑场信号； Rn+1"和 Rn+1'内容相同， Rn+1' 为黑场信号。 本实施例中， 对于 LED驱动信号不做处理， 即 LED背光始终是亮的。 由于 Rn"、 Ln"、 Rn+1"、 Ln+1"帧中存在 3D图像内容， 而在第 Rn，、 Ln，、 Rn+1，、 Ln+1，帧中为黑场即不存在内容。 因而左眼接收到的信号中， 前一部分是图像 内容， 后一部分由于黑场而没内容。 右眼也是如此。
应用本发明的实施例二提供的用于 3D显示的方法，和以往解决方案相比， 至少有以下突出优点： 一是解决了左右画面串扰问题。液晶显示的机理决定了在显示下一帧画面 时会有上一帧的残留存在， 这对于 3D显示来说是不允许的， 否则会存在左右 眼图像的串扰， 大大降低甚至无法实现 3D感觉。 而本发明实施例所提供的方 案可以解决此问题。 将有串扰的那一帧插入黑场， 虽说有该帧存在， 但该帧中 没有内容且为全黑， 不会引起串扰。
二是整机成本低。 和其他 3D 显示方案相比， 本发明实施例不需要昂贵的 光学屏幕或者光学膜， 工艺筒单， 大大降低了整机成本。 实施例三： 在实施例二的基础上控制 LED背光信号
本实施例是在实施例二的基础上做的进一步控制， 具体的， 在图 6所示方 法下进一步包括： 电视机中的主板将提取出的同步控制信号发送给所述 LED 背光驱动控制模块； 所述 LED背光驱动控制模块 4艮据所述同步控制信号控制 黑场信号所在帧所对应的 LED驱动信号为关闭。这样，即存在黑场又存在 LED 背光控制。
参见图 8 , 其是根据本发明实施例三的时分 3D图像信号、 LED驱动信号 以及左右眼图像时序图示。其与图 7的区别是：对于 LED驱动信号，在第 Rn"、 Ln"、 Rn+1"、 Ln+1"帧时打开， 在第 Rn，、 Ln，、 Rn+1，、 Ln+Γ帧时关闭。 左 目艮接收到的信号中， 前一部分是图像内容， 后一部分由于 LED关闭和黑场， 为暗场。 右眼也是如此。
应用本发明的实施例三提供的用于 3D显示的方法，和以往解决方案相比， 至少有以下突出优点：
一是解决了左右画面串扰问题。液晶显示的机理决定了在显示下一帧画面 时会有上一帧的残留存在， 这对于 3D显示来说是不允许的， 否则会存在左右 眼图像的串扰， 大大降低甚至无法实现 3D感觉。 而本发明实施例所提供的方 案可以解决此问题。 当有串扰的那一帧显示时， 既没有画面内容， 又关闭 LED 背光因而看到的只是一幅黑色画面， 不会引起串扰。
二是降低了背光源的能耗。 本发明实施例中在关闭 LED 光源期间， 能耗 几乎为零。 LED控制信号的占空比为 50%, 能耗节约接近 50%。
三是整机成本低。 和其他 3D 显示方案相比， 本发明实施例不需要昂贵的 光学屏幕或者光学膜， 工艺筒单， 大大降低了整机成本。 实施例四：

上述向眼镜发送镜片开闭信号的方式包括： 红外、 射频或蓝牙的方式。 比， 至少有以下突出优点：
