一种用于降低快门式 3D液晶显示串扰的方法、 装置以及液 晶显示器 本申请要求于 2012 年 8 月 17 日提交中国专利局、 申请号为 201210295623.7、 发明名称为 "一种用于降低快门式 3D液晶显示串扰的方 法、 装置以及液晶显示器" 的中国专利申请的优先权， 上述专利的全部内容 通过引用结合在本申请中。 技术领域
本发明涉及快门式 3D液晶显示技术，尤其涉及一种用于降低快门式 3D 液晶显示串扰的方法、 装置以及相应的液晶显示器。
背景技术
快门式 3D液晶显示的工作原理是使液晶面板依次显示左眼图像和右眼 图像， 同时控制快门目艮镜的闭合来使人的左目艮看到左眼图像， 右眼看到右眼 图像。 如果此时观看者左眼看到了右眼图像， 右眼看到了左眼图像， 观看者 的人眼中就会感到串扰现象。
液晶由于存在保持（hold )特性， 其存在一定的反应时间， 导致液晶面 板在显示一帧图像时总是会残留上一帧未响应完的图像，如果液晶面板本身 无法区分左右眼的图像， 无论人们如何调整快门目艮镜的同步， 总是会存在串 扰的现象。
为了降低该串扰， 通常的方法是压缩每帧图像数据传输的时间， 或者采 用背光扫描的技术， 提高图像的动态响应。

参见图 5中所示，每个第二灰阶对照表中存储了左右眼图像的一个扫描 行中在相应位置具有不同灰阶值的各像素点的灰阶值调整关系。 例如， 假设 图 5为第一扫描行对应的第二灰阶对照表。对于对应位置的左眼图像和右眼 图像的像素点 （例如均为第一行第 5像素点）， 若左右眼图像的像素点的灰 P介值组合为 255/1 , 即其左眼图像该像素点的灰阶值为 255 ,右眼图像该像素 点的灰阶为 1 ; 则从该第二灰阶对照表中找到其对应的第二目标灰阶值组合 为 249/22 , 即需要将左眼图像的该像素点的灰阶值从 255调整到 249, 需要 将右眼图像的该像素点的灰阶值从 1调整到 22。左右眼图像的像素点相应具 有其他灰阶值组合均可以从该第二灰阶对照表中查到。该扫描行的其他位置 的像素点如果左右眼图像中灰阶值不同也采用该第二目标灰阶对照表。
其中，每一扫描行的第一灰阶对照表与第二灰阶对照表需满足如下的关 系：
以左右眼灰阶组合为 255/0时量测到的左右眼交叠后的左眼的亮度值作 为最大亮度， 以左右眼灰阶组合为 0/255时量测到的左右眼交叠后左眼的亮 度值作为最小亮度， 以所述最大亮度对应灰阶值为 255 , 以所述最小亮度对 应灰 P介值为 0 , 形成一条新三维灰阶亮度曲线 （ gamma curve );
第二灰阶对照表中所有第二目标灰阶值组合左右眼交叠后所形成的亮 度与所述新三维灰阶亮度曲线上对应位置的亮度偏差在 3%以内；
第一灰阶对照表中所有第一目标灰阶值所形成的亮度与所述新三维灰 阶亮度曲线上对应位置的亮度偏差在 3%以内。
对于如何产生每一扫描行对应的第一灰阶对照表以及第二灰阶对照表， 以及同一扫描行对应的第——灰阶对照表和第二灰阶对照表之间的关系的 原理在后文会以举例的方式进行说明。
可以理解的是， 本发明实施例中以第一灰阶对照表和第二灰阶的对照表 的形式来存储每一扫描行的左右眼各像素点的原始灰 P介值以及需要调整到 的灰阶值的信息， 当然以其他形式（例如一一映射方式）也可以用来存储这 些信息， 理应在本发明所保护的范围之内。
如图 6所示， 是本发明用于降低快门式 3D液晶显示串扰的方法的一个 实施例的流程示意图。 其包括如下流程：
步骤 S60: 接收原始左眼图像与右眼图像的数字信息， 该接收的原始左 眼图像与右眼图像的数字信息包括当前帧的左眼图像中各像素点的原始灰 P介值 , 以及当前帧的右眼图像中各像素点的原始灰 P介值；
步骤 S61 : 比较当前扫描行中所述左眼图像的数字信息与所述右眼图像 的数字信息中的所有对应像素点的灰阶是否相同；
如果步骤 S61中比较到结果为相同，则流程转至步骤 S62;如果步骤 S61 中比较到结果为不同， 则流程转至步骤 S63 ; 直至将当前扫描行中所有的像 素点比较结束；
步骤 S62 , 将在步骤 S61中比较结果为相同的所有左右眼图像的像素点 的灰阶值根据所述图像像素点所处当前扫描行对应的第一灰阶对照表进行 调整， 将每一左右眼灰阶值调整为与其对应的各第一目标灰阶值； 其中， 每 一扫描行的第一灰阶对照表均被预先定义， 第一灰阶对照表中每一原始灰阶 均对应于一个第一目标灰阶值， 具体地， 在该步骤中， 根据比较结果为相同 的左右眼图像像素点的灰阶值组合，搜索所述预先存储的所述当前左右眼图 像像素点所在的扫描行对应的第一灰阶对照表，找到与各左右眼图像像素点 灰阶值相对应的各第一目标灰阶值； 将所有比较结果为相同的左右眼图像像 素点的灰阶值， 均调整到其所对应的各第一目标灰阶值上
步骤 S63 , 将在步骤 S61中所述比较结果不相同的左右眼图像的所有像 素点的灰阶值根据所述图像像素点所处的当前扫描行对应的第二灰阶对照 表进行调整，将每一左右眼灰阶分别调整为与其相对应的各第二目标灰阶组 合中对应的左右眼灰阶值； 其中， 所述每一扫描行对应的第二灰阶对照表均 被预先定义，所述第二灰阶对照表中每一原始左右眼灰阶组合均对应于一个 左右眼第二目标灰阶值组合。 在该步骤中， 具体地， 根据比较结果为不同的 左右眼图像像素点的灰阶值组合，搜索预先存储的所述当前左右眼图像像素 点所处的扫描行对应的第二灰阶对照表，找到与各左右眼图像像素点灰阶值 组合相对应各个第二目标灰阶值组合，每个第二目标灰阶值组合中包括一个 左眼第二目标灰阶值与一个右眼第二目标灰阶值； 将所有比较结果为不同的 左右眼图像像素点的灰 P介值分别调整到其所对应的各第二目标灰阶值组合 中的左眼第二目标灰阶值和右眼第二目标灰阶值上。
步骤 S64 , 当对左右眼图像当前扫描行的所有像素点调整结束后， 进一 步判断当前帧左右眼图像中所有扫描行的像素点的灰阶值是否已调整完 毕？
如果判断结果为未调整完毕， 则在步骤 S65中， 将下一扫描行置为当前 扫描行， 并将流程转向步骤 S61 , 对下一扫描行中的左右眼图像的各像素的 灰阶值进行调整；
如果判断结果为已全部调整完毕， 则在步骤 S66中， 将所有扫描行均经 灰阶调整后的左眼图像与右眼图像的数字信息传送出去。
进一步的， 在本发明的一个实施例中， 在步骤 S66中进一步包括： 緩存 其中一眼（如左眼）经灰阶调整后的图像， 并与另一眼经灰阶调整后的图像 按顺序传送出去。
其中，每一扫描行的第一灰阶对照表与第二灰阶对照表需满足如下的关 以左右眼灰阶组合为 255/0时量测到的左右眼交叠后的左眼的亮度值作 为最大亮度， 以左右眼灰阶组合为 0/255时量测到的左右眼交叠后左眼的亮 度值作为最小亮度， 以所述最大亮度对应灰阶值为 255 , 以所述最小亮度对 应灰阶值为 0, 形成一条新三维灰阶亮度曲线；
第二灰阶对照表中所有第二目标灰阶值组合左右眼交叠后所形成的亮 度与所述新三维灰阶亮度曲线上对应位置的亮度偏差在 3%以内；
第一灰阶对照表中所有第一目标灰阶值所形成的亮度与所述新三维灰 阶亮度曲线上对应位置的亮度偏差在 3%以内。
下面将结合图 7A至图 16, 以一个筒单实例对本发明中如何产生每一扫 描行对应的第一灰阶对照表以及第二灰阶对照表， 以及同一扫描行对应的第 ——灰阶对照表和第二灰阶对照表之间的关系的原理进行进一步的说明。
如图 7A和图 8A所示，是本发明一个实施例中 3D液晶显示器接收的原 始左眼和右眼图像。 在其中一个扫描行中， 示出了四个像素点， 即&、 b、 c、 d点， 此处仅为说明的方便， 非为限制在一个扫描行中仅存在四个像素点。 在 a点的左眼灰阶值和右目艮灰阶值分别为 255和 0, 在 b点的左眼灰阶值和 右目艮灰阶值分别为 255和 255 , 在 c点的左眼灰阶和右目艮灰阶值分别为 0和 255 , 在 d点的左目艮灰阶值和右目艮灰阶值分别为 0和 0。 由于 a点和 c点的左 右眼灰阶值不同， 我们称之为三维静态信号， 由于 b点和 d点的左右目艮灰阶 值相同， 我们称之为二维静态信号。
在一个采用单区闪烁式的 LED背光的 3D液晶显示器中，由于液晶反应 的时间不足， 即会造成左右眼串扰的现象， 如图 7B和图 8B所示， 是图 7A 和图 8A实际显示出来的效果图。 从中可以看出， 由于左右眼串扰， 使左眼 图像中的 a点和 c点的亮度发生了变化，使原本应该显示相同亮度的 a和 b, 以及 c和 d显示出了不同的亮度； 同样， 使右眼图像中的 a点和 c点的亮度 发生了变化， 使原本应该显示相同亮度的 a和 d, 以及 b和 c显示出了不同 的亮度。 从中可以看出， 在左右眼的三维静态图像中， 在当前扫描行中， 当 左右眼图像中某位置的像素点的原始灰阶值不同时， 此位置处在交叠后才会 产生左右眼串扰， 该串扰会使原来最亮处的亮度降低， 使原来最暗处的亮度 下降； 而当左右眼某位置的像素点的原始灰阶值相同时， 此位置处在交叠后 不会产生左右眼串扰， 且亮度不会有任何改变。 为了便于叙述， 下文中将左 右眼图像中相应位置具有不同灰阶值的像素点称为 "三维静态信号"， 将具 有相同灰阶值的像素点称为二维静态信号。如果将二维静态信号的灰阶值进 行调整， 以使其亮度适应变化后的三维静态信号处的灰阶亮度（例如， 将三 维静态信号最亮处降低亮度， 最暗处提高亮度， 其他的亮度也相应调整）， 或者同时对三维静态信号的灰阶值进行微调，从使三维静态信号与二维静态 信号之间的亮度差距与原始图片中的亮度差距相适应，从而即可以消除或减 少交叠后出现的左右眼串扰。
在本发明的实施例中， 发明人考虑到， 当左右眼某像素点的灰阶值组合 为 255/0时， 由于液晶翻转需要时间， 经测量发现， 此种灰阶值组合中左眼 的灰阶亮度， 比左眼为 255搭配其他任何的右眼灰阶值中的亮度都要小， 即 在这种组合下， 左眼所呈现的灰阶亮度变化最大。 而在左右眼某像素点的灰 P介值组合为 0/255时， 由于液晶翻转需要时间， 经测量发现， 此种灰阶值组 合中左眼的灰阶亮度， 比左眼为 0搭配其他任何的右眼灰阶值中的亮度都要 大， 即在这种组合下， 左眼所呈现的灰阶亮度变化最大。 可以把左右眼某像 素点的灰阶值组合为 255/0时， 左眼呈现的亮度作为最大的亮度； 把左右眼 某像素点的灰阶值组合为 0/255时， 左眼呈现的亮度作为最小的亮度， 从而 形成一条新三维灰阶亮度曲线 ,将当前扫描行的原始的左右眼图像上各像素 点的灰阶值的亮度调整到该与该新三维灰阶亮度曲线相适应， 即可以消除或 减少左右眼串扰现象。
故对图 7B中 A点的左眼进行测量， 可以获得左右眼交叠后在 a点左眼 处的透光率与时间的曲线图， 如图 9所示。
其中， 左侧的矩形为 LED背光开启的时间， 其与曲线交叠的面积（阴 影处）即为 a点左眼处通过亮度， 对于不同的扫描行， LED北光开启的时间 位置是不同的，所以对于不同的扫描行，在 a点处测量到的亮度也是不同的。
同理， 故对图 7B中 c点的左眼进行测量， 可以获得左右眼交叠后在 c 点左眼处的透光率与时间的曲线图， 如图 10所示。
其中， 左侧的矩形为 LED背光开启的时间， 其与曲线交叠的面积（阴 影处） 即为 c点左眼处通过的亮度。 根据图 9和图 10可以绘制出当前扫描行处的新三维灰阶亮度曲线 （如 图 11所示）。 其中， 把图 9阴影处面积作为新三维灰阶亮度曲线的最大亮度 (对应于灰阶值 "255" ); 把图 10阴影处面积作为新三维灰阶亮度曲线的最 小亮度（对应于灰阶值 " 0" )。 由于一般常理， 液晶面板的亮度值与灰阶值 存在固定的关系， 例如在一个实施中， 亮度值等于灰阶值的 2.2次方再乘上 一个常数系数，故知道了亮度的最大值 (对应于灰阶值 "255" )与最小值（对 应于灰阶值 "0" ) ,便可以绘制出完整的新三维灰阶亮度曲线。
如图 11 所示， 其中， 以实线表示的曲线即为新三维灰阶亮度曲线， 以 虚线表示的曲线即为当前扫描行处原始图片中的灰阶亮度曲线。 可以知， 在 新三维灰阶亮度曲线中， 将原来的最大亮度值降低了， 而将原来的最小亮度 值升高了。
根据该新三维灰阶亮度曲线， 即可以确定用于二维静态信号的灰阶值调 整的第一灰阶对照表， 和用于三维静态信号的灰阶值调整的第二灰阶对照 表。
只需将二维静态信号（左右眼灰阶值相同的像素点）的灰阶值进行调整， 使其亮度符合新三维灰阶亮度曲线。例如对于左眼和右眼灰阶值同为 255的 象素点， 如果需要使其亮度符合新的三维灰阶亮度（最大值 80% ), 需要降 低左右眼的灰阶值， 经测量发现， 将二维静态信号的左右眼灰阶值降为 249 时， 其测量得到的亮度值（80% )与新三维灰阶亮度曲线的最大亮度值相符 合。 这就建立了一个对应关系， 即原始左右眼图像某个像素点的灰阶值组合 为 255/255 , 其需要调整到的第一目标灰阶值组合为 249/249, 请参见图 12 所示。
同理可以获得其他二维静态信号的对应关系，如原始左右眼图像某个像 素点的灰阶值为 254/254时，其需调整到的第一目标灰阶值组合 247/247时， 其测量得到的亮度值 ( 79% )才与新三维灰阶亮度曲线的最大亮度值相符合， 请参见图 13所示。
根据上述的方法， 即可以形成第一灰阶对照表， 即可以通过测量获得当 前扫描行处的所有二维静态信号需要调整到的第一目标灰阶值，每一扫描行 的第一灰阶对照表完成后， 将其存储在 3D液晶显示器的存储器中。 在其他的实施例中， 可以将二维静态信号进行其他的调整， 而无需完全 调整到符合新三维灰阶亮度曲线， 例如可以将调整后的灰阶对应的亮度与新 三维灰阶亮度曲线有一定范围的差异（如 3% )也可基本实现本发明的目的， 即符合：
(调整后的灰阶亮度值-新三维灰阶亮度曲线相应处亮度值 ) /新三维灰 阶亮度曲线相应处亮度值） *100%<3%
故， 当前扫描行处的第一灰阶对照表不是唯一的， 但如果该第一灰阶对 照表已被存储， 则在附图 6中的对二维静态信号进行调整时即调用该已存储 的第一灰阶对照表进行。
根据上述原理， 可以对图 7A中的二维静态信号 b点和 d点的灰阶值进 行调整， 即将 b点的灰阶值降低， 将 d点的灰阶值提高； 同时对图 7B中的 二维静态信号 b点和 d点的灰阶值进行调整， 即将 b点的灰阶值降低， 将 d 点的灰阶值提高。 调整后的左右眼交叠效果图分别如图 7C和图 8C所示。 从中可以看出， 经过灰阶调整后， 基本消除了左右眼串扰。
根据上述原理， 可以获得不同扫描行对应的新三维灰阶亮度曲线， 同时 可以获得不同扫描行所对应的各第一灰阶对照表。
同时， 需要对三维静态信号进行灰阶调整， 将其匹配到上述的新三维灰 阶亮度曲线上， 下面通过一个实例来说明如何获得每一扫描行所对应的第二 灰阶对照表。
参见图 14所示， 例如， 原始左右眼图像在当前扫描行中某个位置的像 素点左右眼的灰阶值组合为 255/60,则其在新三维灰阶亮度曲线中分别对应 的亮度为 80%和 29%。 此时需要通过光学量测， 获得调整后的某个三维静态 信号组合其左右眼交叠后最大的亮度为 80%, 最小的亮度为 29%, 最后发现 当该调整后左右眼灰阶值组合为 249/40时，其交叠后产生的最大亮度和最小 亮度刚好能符合该新三维灰阶亮度曲线。 如图 15和图 16所示， 图 15中的 阴影面积为对应的最大亮度值， 图 16 中的阴影面积为对应的最小亮度值。 这就建立了一个对应关系 , 即原始左右眼图像的某个像素点的灰阶值组合为 255/60, 其需要调整到的第二目标灰阶值组合为 249/40。
同理可以获得其他三维静态信号的对应关系，如原始左右眼图像的某个 像素点的灰阶值组合为 254/50时， 当将其调整到 247/37时， 其测量得到的 最大亮度值和最小亮度值才与新三维灰阶亮度曲线的最大亮度值相符合。
根据上述的方法， 即可以形成第二灰阶对照表， 即可以通过测量获得当 前扫描行处的所有三维静态信号需要调整到的第二目标灰阶组合， 并将该第 二灰阶对照表进行存储到 3D液晶显示器中。
在其他的实施例中， 可以将三维静态信号进行其他的调整， 而无需完全 调整到新三维灰阶亮度曲线， 例如可以将调整后的灰阶对应的亮度与新三维 灰阶亮度曲线有一定范围的差异（如 3% )也可基本实现本发明的目的， 即 符合：
(调整后的灰阶最大 /最小亮度值 -新三维灰阶亮度曲线相应处最大 /最 小亮度值） /新三维灰阶亮度曲线相应处最大 /最小亮度值） *100%<3%
故， 当前扫描行处的第二灰阶对照表不是唯一的， 但如果该第二灰阶对 照表已被存储， 则在附图 6中的对三维静态信号进行调整时即调用该已存储 的第二灰阶对照表进行。
相应地， 本发明还提供了一种快闪式 3D液晶显示器， 其包括上述图 1 至图 3所描述的用于降低快门式 3D液晶显示串扰的装置， 其实现原理可以 结合上述图 1至图 16的描述， 所有细节均结合上述对图 1至图 16的描述， 在 匕不进行赘述。
实施本发明， 通过预先获得每一扫描行的新三维灰阶亮度曲线， 通过预 先的测量获得每一扫描行所对应的第一灰阶对照表和第二灰阶对照表， 并将 其存储在 3D液晶显示器中。 在 3D液晶显示器中接收到原始左右眼信号后， 将原始左眼信号和右眼信号中的二维静态信号按照第一灰阶对照表进行调 整， 对三维静态信号按照第二灰阶对照表进行调整， 经过上述的调整可以降 低或消除左右眼的串扰。
将本发明的装置及方法应用在低成本的整区背方闪烁的 3D液晶显示器 中， 可以达到扫描式背光相当程度的低左右眼串扰， 将本发明的装置及方法 应用在反应时间较慢的液晶中， 亦可以降低或消除左右眼串扰， 从而一定程 度上可以减少 3D液晶显示器消除或降低的左右眼串扰所花费的成本。
采用本发明的装置及方法，花费成本不高却能达到很好的降低或消除左 右眼串扰的效果。
以上所揭露的仅为本发明较佳实施例而已， 当然不能以此来限定本发明 之权利范围， 因此等同变化， 仍属本发明所涵盖的范围。

19、 如权利要求 15所述的液晶显示器， 其中， 所述每一扫描行的第一 灰阶对照表与第二灰阶对照表存在如下关系：
以左右眼灰阶组合为 255/0时量测到的左右眼交叠后的左眼的亮度值作 为最大亮度， 以左右眼灰阶组合为 0/255时量测到的左右眼交叠后左眼的亮 度值作为最小亮度， 以所述最大亮度对应灰阶值为 255 , 以所述最小亮度对 应灰阶值为 0, 形成一条新三维灰阶亮度曲线；
所述第二灰阶对照表中所有第二目标灰阶值组合左右眼交叠后所形成 的亮度与所述新三维灰阶亮度曲线上对应位置的亮度偏差在 3%以内；
所述第一灰阶对照表中所有第一目标灰阶值所形成的亮度与所述新三 维灰阶亮度曲线上对应位置的亮度偏差在 3%以内。
