3D显示控制方法及 3D显示控制装置 技术领域
本发明的实施例涉及一种 3D显示控制方法及 3D显示控制装置。 背景技术
随着科技的发展， 三维（3D )立体显示， 尤其是棵眼 3D立体显示已成 为显示领域的趋势之一。 3D立体显示， 通过信号控制或辅助装置，使观看者 的左右眼看到有 "双眼视差" 的一对 "立体图像对" ， 基于双目视差原理使 得观看者能够观看到产生 3D效果的三维立体图像。 如图 la所示， 其中一种 棵眼 3D立体显示的基本原理为： 在第一时刻， 通过光栅装置 33使显示面板 30的亚像素 31所发出的光射在不同视场内， 观看者的左眼和右眼落在不同 视场内， 从而产生 3D立体感觉。 并且， 如图 lb所示， 在第二时刻， 改变奇 数列和偶数列的亚像素所对应的光栅装置的光栅状态 (即遮光区 33a和透光 区 33b变换） ， 这时， 由于人眼的刺激滞留效应， 观看者的单眼会得到来自 奇数列和偶数列的亚像素的刺激， 单眼分辨率并不降低。
现有技术中， 当光栅装置的光栅状态由第一时刻变为第二时刻时， 显示 面板也正在进行自上而下的图像刷新， 这时， 就会出现第一时刻的图像和第 二时刻的图像同时存在的现象， 造成图像串扰。 如图 2所示， 第二帧画面刚 刚刷新到第四行， 此时， 上半部分对应第二时刻的光栅状态， 下半部分对应 第一时刻的光栅状态， 产生图像串扰。 发明内容

为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发 明实施例的附图， 对本发明实施例的技术方案进行清楚、 完整地描述。显然， 所描述的实施例是本发明的一部分实施例， 而不是全部的实施例。 基于所描 述的本发明的实施例， 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
本发明实施例提供了一种 3D显示控制方法及 3D显示控制装置，用以改 善现有技术中 3D显示存在的图像串扰问题。
下面结合 3D显示系统说明本发明实施例提供的 3D显示控制方法及 3D 显示控制装置。
所述 3D显示系统至少包括：显示面板和位于显示面板上方的光栅装置。 本发明的实施例通过以列扫描的方式实现图像显示的显示面板为基础， 结合 光栅装置， 实现一种图像串扰较小的 3D图像显示。
下面首先介绍本发明实施例提供的列扫描式显示面板以及 3D显示系统。 如图 3所示， 本发明实施例所提供的列扫描式显示面板， 包括： 沿列方 向设置的一组栅线 35和沿行方向设置的一组数据线 36。 其中， 相邻两条栅 线 35和相邻两条数据线 36界定了一个亚像素 31。 在每一个亚像素 31内包 括： 薄膜晶体管 37和像素电极 38。 其中， 薄膜晶体管 37的栅极与栅线 35 连接，薄膜晶体管 37的源极与数据线 36连接，薄膜晶体管 37的漏极与像素 电极 38连接。
多条栅线 35和数据线 36连接到驱动控制电路， 某一时刻， 只能对一列 亚像素进行扫描。 例如， 第一时刻， 栅线 G1输入高电压， 其他栅线输入低 电压， 与栅线 G1对应的这一列亚像素 31内的薄膜晶体管 37打开， 数据线 36通过薄膜晶体管 37向像素电极 38输入信号电压， 实现图像显示。 第二时 刻， 栅线 G2输入高电压， 其他栅线输入低电压， 与栅线 G2对应的这一列亚 像素 31内的薄膜晶体管 37打开， 数据线 36通过薄膜晶体管 37向像素电极 38输入信号电压， 实现图像显示。 以此类推， 显示面板按照列扫描方式， 刷 新每一列亚像素。
如图 4所示， 本发明实施例提供的 3D显示系统， 包括： 如图 3所示的 列扫描式显示面板 30、 位于列扫描式显示面板 30上方的光栅装置 33 , 以及 与列扫描式显示面板 30和光栅装置 33相连的控制设备 32。
参见图 5 , 图 5为图 4所示的光栅装置 33的具体结构示意图， 光栅装置 33包括多个光栅单元， 每个光栅单元对应相邻的两列亚像素， 每个光栅单元 包括第一区域 33b和位于第一区域 33b两侧的等大的第二区域 33a, 所述第 一区域 33b和两个第二区域 33a在当前帧画面未刷新时分别显示为遮光状态 和透光状态。
控制设备 32, 用于当光栅装置 33存在一个光栅单元的第一区域 33b对 应当前列亚像素和未被刷新的相邻列亚像素时， 控制所述第一区域 33b显示 为遮光状态， 以及
当第一列亚像素在当前帧画面未刷新时左侧区域对应第一区域时， 在刷 新第一列亚像素时，控制光栅装置 33对应所述第一列亚像素的左侧区域部分 显示为遮光 态。
一个实施例， 所述控制设备 32, 进一步用于控制光栅装置 33对应已刷 新完毕的列亚像素的区域显示为当前帧画面刷新完毕后的光栅状态。 另一个实施例， 所述控制设备 32, 进一步用于当前列亚像素刷新结束之 后，控制光栅装置 33对应当前列亚像素和已经刷新的相邻列亚像素的区域显 示为当前帧画面刷新完毕后的光栅状态。
本发明实施例的 3D显示控制系统， 进一步包括背光源， 所述光栅装置 位于显示面板的出光面一侧， 或者， 所述光栅装置位于背光源和显示面板之 间。
所述光栅装置 33为主动式视差挡板。主动式视差挡板可以釆用液晶面板 制作， 还可以釆用电致变色材料制成的面板制作； 此外， 主动式视差挡板还 可以是其它可以主动控制其呈现周期性交替排列的透光区域和遮光区域的光 学器件。
所述列扫描的显示面板可以为薄膜晶体管液晶显示面板、 等离子显示面 板或电激发光显示面板等， 在本发明所举实施例中， 列扫描的显示面板为薄 膜晶体管液晶显示面板，一组栅线沿列方向设置，一组数据线沿行方向设置。
基于图 4所示的系统，说明本发明实施例实现 3D显示的控制方法及 3D 显示控制装置。
参见图 6, 本发明实施例提供一种 3D显示控制方法， 包括以下步骤：
521、 依次获取当前帧图像中与显示面板上的各列亚像素对应的左眼图 像数据或右眼图像数据；
522、 根据所述各列亚像素对应的左眼图像数据或右眼图像数据依次更 新上一帧图像中各列亚像素显示的图像， 同时更新上一帧图像对应的光栅装 置的遮光区域和透光区域， 实现棵眼 3D图像显示。
其中步骤 S22具体包括： 当当前帧中正在更新任意一列亚像素时， 遮蔽 光栅装置的所有与所述任意一列亚像素对应的透光区域；
当当前帧中所述任意一列亚像素完全更新完毕后， 如果所述光栅装置与 所述任意一列亚像素对应的区域也对应于与所述任意一列亚像素相邻的下一 列亚像素， 当所述相邻的下一列亚像素还未更新完毕时， 则仍保持遮蔽所述 光栅装置与所述任意一列亚像素和所述相邻的下一列亚像素都对应的透光区 域， 当所述相邻的下一列亚像素完全更新完毕时， 则所述光栅装置与所述任 意一列亚像素和所述相邻的下一列亚像素都对应的区域才即刻进行遮光和透 光的变换； 如果所述光栅装置与所述任意一列亚像素对应的区域不对应于其 它列亚像素， 则当所述任意一列亚像素完成更新时， 所述光栅装置与所述任 意一列亚像素对应的区域直接进行遮光和透光的变换。
下面结合附图具体说明图 6所示的 3D显示控制方法。
本发明实现 3D显示的简单过程为：
显示面板上针对每一帧图像按照一列左眼图像，一列右眼图像间隔显示； 一列图像对应一列亚像素。 相邻两帧图像， 针对每一列亚像素， 在上一帧图 像中显示左眼图像， 当前帧图像中显示右眼图像。 也就是说， 控制设备在上 一帧图像显示之前获取的图像数据依次为 1L-2R-3L-4R-5L-6R- ； 在当前 帧图像显示之前获取的图像数据依次为 1R-2L-3R-4L-5R-6L- 。 1、 2、 3、 4、 5、 6表示图像中各列亚像素的序号。 "R" 表示显示右眼图像， "L" 表 示显示左眼图像。
光栅装置根据显示面板图像的更新， 同时更新与亚像素对应的遮光区域 和透光区域。
设上一帧图像显示面板上的奇数列亚像素显示左眼图像（L ) , 偶数列 亚像素显示右眼图像 （ R ) , 即控制设备获取的图像数据依次为
1L-2R-3L-4R-5L-6R- , 且当上一帧图像对应的光栅装置中与第 2n-l和第
2n 列亚像素均对应且具有预设宽度的区域为透光区域， 其余区域为遮光区 域， n=l、 2、 3 , 如图 7所示， 为上一帧图像显示面板和光栅结构显 示原理示意图。
步骤一： 依次获取当前帧图像中与显示面板上的各列亚像素对应的左眼 图像数据或右眼图像数据。 如图 8为多列亚像素对应的图像， 控制设备获取 的图像数据依次为 1R-2L-3R-4L-5R-6L- 。
步骤二： 根据图像数据 1R-2L-3R-4L-5R-6L- ...... , 依次更新当前帧图像 中各列亚像素显示的图像， 同时更新当前帧图像对应的光栅装置的遮光区域 和透光区域， 实现棵眼 3D图像显示。
更新后的当前帧图像中各列亚像素显示的图像如图 8所示。 将当前帧图 像对应的光栅装置中与第 2n和第 2n+l列亚像素均对应且具有预设宽度的区 域更新为透光区域， 其余区域更新为遮光区域， n=l、 2、 3 ； 如图 9 所示。
下面具体介绍更新当前帧图像的每一列亚像素和光栅装置对应区域的遮 光区域和透光区域的具体过程， 以实现无串扰的棵眼 3D图像显示的过程。 包括两种情况：
第一种情况： 当上一帧图像的光栅装置中与第 2n-l和第 2n列亚像素均 对应且具有预设宽度的区域为透光区域， 其余区域为遮光区域时， 则将当前 帧图像对应的光栅装置中与第 2n和第 2n+l列亚像素均对应且具有预设宽度 的区域更新为透光区域， 其余区域更新为遮光区域， n=l、 2、 3 ； 也 即将图 7所示的图像显示和光栅状态更新为图 9所示的图像显示和光栅状态。
第二种情况： 当上一帧图像的光栅装置中与第 2n和第 2n+l列亚像素均 对应且具有预设宽度的区域为透光区域， 其余区域为遮光区域时， 则将当前 帧图像对应的光栅装置中与第 2n-l和第 2n列亚像素均对应且具有预设宽度 的区域更新为透光区域， 其余区域更新为遮光区域， n=l、 2、 3 。 也 即将图 9所示的图像显示和光栅状态更新为图 7所示的图像显示和光栅状态。
针对第一种情况， 具体为：
当当前帧图像开始更新第一列亚像素的图像之前， 遮蔽光栅装置与第一 列和第二列亚像素均对应且具有预设宽度的透光区域， 使得与第一列和第二 列亚像素对应的光栅装置区域完全处于遮光区域； 当完全更新完第一列亚像 素的图像之后， 将光栅装置与第一列亚像素靠近显示面板边框的预设宽度对 应的区域更新为透光区域， 同时更新第二列亚像素的图像， 并遮蔽光栅装置 与第三列和第四列亚像素均对应且具有预设宽度的透光区域， 使得第三列和 第四列亚像素对应的光栅装置区域完全处于遮光区域；
当完全更新完第二列亚像素的图像之后，开始更新第三列亚像素的图像； 当完全更新完第三列亚像素的图像之后， 将光栅装置与第二列和第三列亚像 素均对应且具有预设宽度的区域更新为透光区域， 同时更新第四列亚像素的 图像， 且遮蔽光栅装置与第五列和第六列亚像素均对应且具有预设宽度的透 光区域,使得第五列和第六列亚像素对应的光栅装置区域完全处于遮光区域； 以此类推， 直到最后一列亚像素更新完。
针对第二种情况， 具体为：
当前帧图像开始更新第一列亚像素的图像之前， 遮蔽光栅装置与第一列 亚像素靠近显示面板边框的区域对应的透光区域， 使得第一列亚像素对应的 光栅装置区域完全处于遮光区域； 更新第一列亚像素的图像； 当完全更新完 第一列亚像素的图像之后， 遮蔽光栅装置与第二列和第三列亚像素均对应且 具有预设宽度的透光区域， 同时更新第二列亚像素的图像， 当第二列亚像素 的图像完全更新完之后， 将光栅装置与第一列和第二列亚像素均对应且具有 预设宽度的区域更新为透光区域； 同时更新第三列亚像素的图像；
当完全更新完第三列亚像素的图像之后， 遮蔽光栅装置与第四列和第五 列亚像素均对应且具有预设宽度的透光区域，同时更新第四列亚像素的图像， 当第四列亚像素的图像完全更新完之后， 将光栅装置与第三列和第四列亚像 素均对应且具有预设宽度的区域更新为透光区域； 同时更新第五列亚像素图 像； 以此类推， 依次更新各列亚像素的图像的透光、 遮光状态。
下面结合附图具体说明上述第一种情况图像更新过程。
1、更新第一列亚像素的图像： 当当前帧图像开始更新第一列亚像素的图 像之前， 遮蔽如图 7所示的光栅装置与第一列和第二列亚像素均对应且具有 预设宽度的透光区域， 使得第一列和第二列亚像素对应的光栅装置区域完全 处于遮光区域； 当将第一列亚像素由左眼图像完全更新为右眼图像时， 将光 栅装置与第一列亚像素（靠左侧， 也即靠近显示面板边框侧）对应的区域更 新为透光区域， 如图 10所示。
在更新第一列亚像素对应的光栅装置的遮光区或透光区的状态时， 因第 一列亚像素和第二列亚像素均显示右眼图像， 会形成串扰， 本发明的实施例 在更新第一列亚像素的同时， 遮蔽光栅装置与第一列和第二列亚像素均对应 且具有预设宽度的透光区域， 避免了第一列亚像素和第二列亚像素之间显示 串扰的问题。 以下图像更新过程也是同样的道理。
2、 更新第二列亚像素的图像： 更新第二列亚像素的过程中， 光栅装置的 遮光区和透光区的状态不变。
当第二列亚像素由右眼图像完全更新为左眼图像时，遮蔽如图 10所示的 光栅装置与第三列和第四列亚像素均对应且具有预设宽度的透光区域， 使得 第三列和第四列亚像素对应的光栅装置区域完全处于遮光区域， 如图 11 所 示。
3、更新第三列亚像素的图像： 当第三列亚像素由左眼图像完全更新为右 眼图像时，将图 11所示的光栅装置与第二列和第三列亚像素均对应且具有预 设宽度的区域更新为透光区域， 如图 12所示。 4、更新第四列亚像素的图像： 当第四列亚像素完全由右眼图像更新为左 眼图像时， 遮蔽光栅装置与第五列和第六列亚像素均对应且具有预设宽度的 透光区域,使得图 12所示的第五列和第六列亚像素对应的光栅装置区域完全 处于遮光区域， 如图 13所示。
5、更新第五列亚像素的图像： 当第五列亚像素完全由左眼图像更新为右 眼图像时， 将光栅装置与第四列和第五列亚像素均对应且具有预设宽度的区 域更新为透光区域， 如图 14所示。
以后的每一列亚像素图像以此类推。
假设第六列亚像素为最后一列亚像素， 更新第六列亚像素的图像如下。 6、更新第六列亚像素的图像： 当第六列亚像素完全由右眼图像更新为左 眼图像时， 将图 14所示的光栅装置与第六列亚像素（最右侧， 也即靠近显示 面板边框侧）对应的区域更新为透光区域。 更新完的图像如图 9所示。
上述为当前帧图像更新的过程， 下面介绍下一帧图像的更新过程， 也即 图 9所示的图像显示和光栅状态更新为图 7所示的图像显示和光栅状态（也 即上述第二种情况的更新过程） 。
1、更新第一列亚像素图像： 当当前帧图像开始更新第一列亚像素的图像 1R之前，遮蔽光栅装置与第一列亚像素靠近显示面板边框的预设宽度区域对 应的透光区域， 使得第一列亚像素对应的光栅装置区域完全处于遮光区域； 更新第一列亚像素的图像，如图 15所示，第一列亚像素的图像由右眼图像更 新为左眼图像。 由于第一列亚像素在更新的过程中完全遮蔽， 第二列亚像素 对应的区域中与第一列亚像素相邻的区域也处于遮光状态， 不会造成第一列 亚像素在更新的过程中与第二列亚像素发生图像的串扰。
2、 更新第二列亚像素图像： 当完全更新完第一列亚像素的图像之后， 遮 蔽如图 15 所示的光栅装置与第二列和第三列亚像素均对应且具有预设宽度 的透光区域， 同时更新第二列亚像素的图像， 当第二列亚像素的图像完全由 左眼图像更新为右眼图像时， 将光栅装置与第一列和第二列亚像素均对应且 具有预设宽度的区域更新为透光区域， 如图 16所示。
3、更新第三列亚像素图像： 当光栅装置与第一列和第二列亚像素之间均 对应且具有预设宽度的区域更新为透光区域之后， 将第三列亚像素的图像由 右眼图像更新为左眼图像。 如图 17所示。 4、 更新第四列亚像素图像： 当完全更新完第三列亚像素的图像之后， 遮 蔽如图 17 所示的光栅装置与第四列和第五列亚像素均对应且具有预设宽度 的透光区域， 同时更新第四列亚像素的图像， 当第四列亚像素的图像完全由 左眼图像更新为右眼图像时， 将光栅装置与第三列和第四列亚像素均对应且 具有预设宽度的区域更新为透光区域， 如图 18所示。
5、更新第五列亚像素图像： 当光栅装置与第三列和第四列亚像素均对应 且具有预设宽度的区域更新为透光区域之后， 将第五列亚像素的图像由右眼 图像更新为左眼图像。 如图 19所示。
以此类推， 依次更新各列亚像素的图像的透光、 遮光状态。
假设第六列图像为最后一列图像， 更新最后一列图像的过程如下。
6、 更新第六列亚像素图像： 当完全更新完第五列亚像素的图像之后， 遮 蔽如图 19所示的第六列亚像素的透光区域， 同时更新第六列亚像素的图像， 当第六列亚像素的图像完全由左眼图像更新为右眼图像时， 将光栅装置与第 五列和第六列亚像素均对应且具有预设宽度的区域更新为透光区域， 如图 7 所示的图像显示和光栅状态。
以此规律向右进行刷新， 直至完成全画面的刷新。 接着进行下一帧画面 的显示和光栅的更新过程。 图像帧之间， 当前一帧图像为图 7所示的图像显 示和光栅状态， 则下一帧图像更新为图 9所示的图像显示和光栅状态， 下下 一帧更新为图 7所示的图像显示和光栅状态， 再下一帧更新为图 9所示的图 像显示和光栅状态。

当完全更新完第二列亚像素的图像之后， 遮蔽光栅装置与第三列和第四 列亚像素均对应且具有预设宽度的透光区域， 使得第三列和第四列亚像素对 应的光栅装置区域完全处于遮光区域， 并开始更新第三列亚像素的图像； 当 完全更新完第三列亚像素的图像之后， 将光栅装置与第二列和第三列亚像素 均对应且具有预设宽度的区域更新为透光区域， 同时更新第四列亚像素的图 像; 当完全更新完第四列亚像素的图像之后， 遮蔽光栅装置与第五列和第六 列亚像素均对应且具有预设宽度的透光区域， 使得第五列和第六列亚像素对 应的光栅装置区域完全处于遮光区域， 并开始更新第五列亚像素的图像； 当 完全更新完第五列亚像素的图像之后， 将光栅装置与第四列和第五列亚像素 均对应且具有预设宽度的区域更新为透光区域， 同时更新第六列亚像素的图 像； 以此类推， 直到最后一列亚像素更新完。
备选地， 当上一帧图像的光栅装置中与第 2n和第 2n+l列亚像素均对应 且具有预设宽度的区域为透光区域，其余区域为遮光区域时， 3D显示控制单 元 92, 具体用于： 当前帧图像开始更新第一列亚像素的图像之前， 遮蔽光栅 装置与第一列亚像素对应的透光区域， 使得第一列亚像素对应的光栅装置区 域完全处于遮光区域； 更新第一列亚像素的图像； 当完全更新完第一列亚像 素的图像之后， 遮蔽光栅装置与第二列和第三列亚像素均对应且具有预设宽 度的透光区域， 同时更新第二列亚像素的图像， 当第二列亚像素的图像完全 更新完之后， 将光栅装置与第一列和第二列亚像素均对应且具有预设宽度的 区域更新为透光区域； 同时更新第三列亚像素的图像；

这里， 需要注意的是， 光栅装置中与第 2n和第 2n+l列亚像素均对应的 透光区域的预设宽度可以等于或不等于光栅装置中与第 2n- l和第 2n列亚像 素均对应的透光区域的预设宽度。
备选地， 所述光栅装置为视差挡板光栅。
这里， 应该注意的是， 当光栅装置的透光区域和遮光区域进行遮光和透 光状态的变换时， 遮光区域和透光区域的尺寸也会发生变化或者不变， 只要 变换后的光栅装置能实现将左眼图像和右眼图像分开即可。 举例说来， 当上 一帧中透光区域的尺寸为 a, 则在下一帧中该透光区域会变换为遮光区域， 则遮光区域的尺寸是 b , b可能等于 a, 也可能不等于 a。
本发明实施例中， 当更新某一列亚像素图像时， 控制光栅装置与， 相邻 列亚像素和该列亚像素对应的区域为遮光区域， 避免刷新当前列亚像素图像 时， 引起相邻列亚像素发生串扰的现象。 发明的精神和范围。 这样， 倘若本发明的这些修改和变型属于本发明权利要 求及其等同技术的范围之内， 则本发明也意图包含这些改动和变型在内。
