Description

一种3D显示装置及其驱动方法和装置 技术领域
本发明涉及到显示装置的技术领域，尤其涉及到一种3D显示装置及其驱动方法。
背景技术
裸眼3D(3 dimention)也是一种3D形式，它通过光栅，区分进入人左右眼的信息，使人感觉有3D的效果，在大尺寸电视上应用较多。但是裸眼3D由于具有挡光光栅设计，在观测过程中，PPI(Pixels Per Inch)降低很多，有时会降低一半的PPI，从而使观看3D效果降低。
虚拟显示技术在目前显示领域中应用十分广泛，通过像素公用，能够使视觉分辨率高于面板物理分辨率。目前韩国三星是使用虚拟技术最多的面板商，在由于OLED(Organic Light-Emitting Diode，有机电激光显示)在做亚像素时，有机物树脂膜(resin pattern)形成工艺难度较大，所以在制作更高的PPI显示屏上遇见瓶颈。通过虚拟技术能够很好的解决这个问题。提高人眼感受到的屏幕分辨率。这种虚拟算法技术命名为pentile技术，由三星进行垄断，在三星S3，S4等高端产品上均得到应用。S4模式的排列图形是菱形状排列，目前最新技术来看，这种排列突破了传统一行或一列RGB排列的模式，这种显示方法只能使用像素公用的虚拟技术进行显示，并且最为难得的是这种排列进行显示的显示效果很好，值得我们借鉴。
如何将裸眼3D技术和虚拟显示技术相结合，制作出高清3D是一个挑战，将3D显示和虚拟算法相结合在目前的相关文献和专利中介绍较少。

具体实施方式
为了提高3D显示装置的裸眼3D显示效果，本发明实施例提供了一种3D显示装置及其驱动方法，在本发明的技术方案中，通过采用异形光栅的设置，以及重新规划采样区域从而改善了3D显示装置的裸眼3D画面时的效果。为了方便对本发明技术方案的理解，下面结合附图及具体实施例对本发明的技术方案进行详细的说明。
首先需要说明的是，为了方便描述，以S1、S2-S10代表亚像素的列序号，R1、R2-R12代表奇数列亚像素组的序号，C1、C2-C12代表偶数列亚像素的序号；并且以行数及列数代表该亚像素的位置。
一并参考图1及图2，图1示出了本发明实施例提供的像素阵列的排列示意图；图2示出了本发明实施例提供的光栅与像素阵列结合的示意图。
本发明实施例提供了一种3D显示装置，该3D显示装置包括像素阵列10以及光栅20，
所述像素阵列10包括：多列亚像素组，每列亚像素组包括M*N个亚像素11，其中M为亚像素11颜色种类，N为大于3的正整数；其中，每个亚像素11为矩形形状，奇数列亚像素组和偶数列亚像素组错位设置；
所述光栅20类似棋盘格形状，包含多个以规则的阵列排列的遮挡矩形21，每个遮挡矩形21用于遮挡列方向的至少一个亚像素11；其中，相邻列中的遮挡矩形21在列方向错位设置，相间一列的列中的遮挡矩形在行方向相对于它们之间的列对称设置，也就是说，相邻奇数列中的遮挡矩形在行方向相对于它们之间的偶数列对称设置，相邻偶数列中的遮挡矩形在行方向相对于它们之间的奇数列对称设置。
在上述实施例中，通过采用错位设置的像素阵列10，同时配合光栅20形成遮挡，实现了对3D显示装置裸眼3D显示的效果的改善，为了方便对本发明实施例的结构以及工作原理的理解，下面结合具体 的附图以及实施例对其进行详细的说明。
如图1所示，图1示出了本发明实施例提供的像素阵列10的排列方式，本发明实施例提供的3D显示装置包含的像素阵列10由多个亚像素组成，多个亚像素11排列成阵列方式，具体的，每列亚像素组包含M*N个亚像素11，其中，M为亚像素11颜色种类，N为大于3的正整数；在本具体实施例中，M的个数为3，所述亚像素11颜色的为红色、绿色及蓝色，即红色亚像素、绿色亚像素及蓝色亚像素，并且在每列亚像素组中，M个亚像素为一个视图单元，且相邻的视图单元对应3D显示中的第一视图及第二视图；即在显示裸眼3D画面时，每列亚像素组中相邻的视图单元分别显示3D画面信号中的第一视图及第二视图；为了方便描述，将显示第一视图的视图单元命名为第一视图单元30，显示第二视图的视图单元命名为第二视图单元40，其具体的排列方式如图1中所示，其中第一视图中的三个亚像素11分别用R1、G1、B1表示，第二视图中的三个亚像素11分别用R2、G2、B2表示，由图1可以看出，在像素阵列10中，第一视图单元30及第二视图单元40交替排列。
在本申请中的像素阵列10中，位于奇数列的亚像素组与位于偶数列的亚像素组交错排列，如图1所示，该交错的方式为多个奇数列的亚像素组高度齐平，多个偶数列的亚像素组高度齐平，且奇数列亚像素组和偶数列亚像素组错位设置宽度为亚像素11在列方向宽度的一半。从而使得像素阵列10中的亚像素11形成三角形阵列。即如图1所示，R、G、B三种颜色的亚像素11排列成三角形阵列，图中RGB三个亚像素11呈“Δ”形状。
如图2所示，图2示出了本发明实施例提供的像素阵列10与光栅20配合的示意图；本实施例提供的光栅20为棋盘格格式，即光栅20中遮挡的遮挡矩形21以及允许光通过的透光矩形交错排列，形成类似黑白棋盘格的形式。如图2所示，图2中的较大的虚框所示的即为光栅20；在具体的设置时，遮挡矩形21之间的设置并不是齐平的，即在不同列之间相邻的两个遮挡矩形21之间位置交错，即在列方向两个相邻的遮挡矩形21有一部分在行方向上重叠；如图2所示，较小的虚框包含了不同列之间相邻的遮挡矩形21位置的交接区域22。
需了解，在本文描述的实施例中，所述交接区域是指遮挡区域在 列方向重叠的区域。
采用交错的设置方式，使得3D显示中将两视图之间对应的信号分别区分到不同的两眼中，减少串扰现象，提高显示的效果。由图2可以看出，遮挡矩形21采用交错的设置方式，在显示时，遮挡了部分的亚像素11。具体的，遮挡矩形21在列方向的宽度为亚像素11单元在列方向宽的7/2倍，在行方向的宽度为单个亚像素11的宽度。因此，一并参考图图3～图6，其中图3为第一视图对应的视图单元，图4为光栅20在第一视图显示时遮挡的位置，图5为第二视图对应的视图单元，图6为光栅20在第二视图显示时遮挡的位置，由图3～图6可以看出，在第一视图及第二视图显示时，光栅20中的遮挡矩形21遮挡到了部分显示的亚像素11，针对本发明中的亚像素11一半被光栅20遮挡而形成色偏的问题，本发明通过对算法的设计，及采样区的重新设计，能够适量解决色偏的问题。具体的详见本发明的3D显示装置的驱动方法。
本发明实施例还提供了一种3D显示装置的驱动方法，所述3D显示装置为上述任一项所述的3D显示装置；该方法包括：
分别将待显示的3D视图的第一视图和第二视图划分为多个视图单元，并确定每一个视图单元中各个颜色的颜色分量，这在后面图16中的1601处示出了；
针对每一个视图的每一个亚像素11，按照该亚像素11对应的矩形采样区所覆盖的、属于该视图的各个视图单元中该亚像素11的颜色的颜色分量确定该亚像素11的发光亮度，这在图16中的1602处示出了。
具体的步骤如下：
步骤一、分别将待显示的3D视图的第一视图和第二视图划分为多个视图单元，并确定每一个视图单元中各个颜色的颜色分量；
具体的，3D显示装置中的一个M个亚像素对应于一个视图单元，M为3。在上述步骤中，可以将第一视图基于3D显示装置的理论上能够达到的像素的个数划分为多个视图单元，本发明实施例中将3个亚像素作为一个理论像素单元，本发明实施例中的理论像素单元对应前述的视图单元，可以为第一视图单元或第二视图单元。之后确定各个理论像素单元中的红、绿、蓝所占的颜色分量。并按照相同的方式，得到第二视图对应的多个理论像素单元以及各个理论像素单元中红、 绿、蓝所占的颜色分量。具体的，可以根据屏幕的视觉分辨率分别将左右眼视图(即第一、第二视图)进行划分。
步骤二、针对每一个视图的每一个亚像素11，按照该亚像素11对应的矩形采样区所覆盖的、属于该视图的各个理论像素单元中该亚像素11的颜色的颜色分量确定该亚像素11的发光亮度。
其中，针对每一个亚像素，确定其对应的矩形采样区与所述多个理论像素单元中的每一个理论像素单元的重叠面积以及在该理论像素单元中该亚像素的颜色对应的颜色分量；确定每一个理论像素单元对应的重叠面积与对应的颜色分量的乘积；根据各个乘积的和以及采样区的面积确定该亚像素的发光亮度。当然在实际应用中，在使用矩形采样区进行采样之后，也可以通过其他方式确定对应亚像素的发光强度。本发明实施例中不再进行详细说明。
在步骤二中，具体采样区设计时，首先判断亚像素11的位置，在亚像素11未位于遮挡矩形21交接区域22时，该亚像素11的采样区域为：
所述采样区为矩形采样区，且该采样区域的列方向上的中线为对应的亚像素11在列方向上的中线，该采样区域在行方向的宽度为亚像素11在行方向宽度的2倍，在列方向上的宽度为亚像素11在列方向宽度的3倍；
针对偶数列的亚像素11，每个亚像素11对应的采样区在列方向覆盖位于该采样区对应的亚像素11下方的亚像素11的一部分；
针对奇数列的亚像素11，每个亚像素11对应的采样区与偶数列的亚像素11对应的采样区相接，且奇数列的亚像素11对应的采样区与偶数列的亚像素11对应的采样区位置相错。
其中，针对偶数列的亚像素11，每个亚像素11对应的采样区在列方向覆盖位于该采样区对应的亚像素11下方的亚像素11的部分介于0～1/2亚像素面积之间。
为了方便理解，下面参考图7～图10，其中，图7示出了第一视图对应的理论像素单元中的蓝色亚像素的排列方式，可以看出蓝色亚像素没有落入交接区域22，采样区不用特殊考虑，图8对应给出了第一视图对应的理论像素单元中的蓝色亚像素的对应的采样区的设计；由图8可以看出，本申请中蓝色亚像素对应的采样区为矩形采样区，且 位于奇数列的亚像素11与位于偶数列的亚像素11对应的采样区连接成一体，在具体的设置时，以S8C6蓝色亚像素为例，其对应的采样区的四个顶点分别位于：S7R3亚像素内、S9R3亚像素内、S7R6亚像素内、S9R6亚像素内，且由图8可以看出，采样区覆盖位于S8C6蓝色亚像素下方的亚像素的部分，且覆盖的部分少于1/2亚像素的面积。针对奇数列蓝色亚像素，以S7R7为例，其对应的采样区的四个顶点分别位于：S6C7亚像素内、S8C7亚像素内、S6C10亚像素内、S8C10亚像素内，且如图8所示，在列方向上S8C6蓝色亚像素对应的采样区与S7R7蓝色亚像素对应的采样区位置相错一个亚像素的宽度，且S8C6蓝色亚像素对应的采样区与S7R7蓝色亚像素对应的采样区在列方向相接。
参考图9和图10，图9示出了绿色亚像素分布情况，图10给出了绿色亚像素对应的采样区的形状，由图9可以看出，位于奇数列的绿色亚像素位于交接区域外，其对应的采样区与蓝色亚像素的采样区的设计相同，而位于偶数列的绿色亚像素位于交接区域22内，其采样区的设计与上述蓝色亚像素的采样区的设计不同。
针对位于奇数列的绿色亚像素，参考图9及图10，为了方便理解，以S3R8绿色亚像素为例进行说明，由于其未位于交接区域22内，因此，其对应的采样区的四个顶点分别位于：S2C6亚像素内、S4C6亚像素内、S2C9亚像素内、S4C9亚像素内。且由图10可以看出，S3R8绿色亚像素对应的采样区包含S3R9亚像素的一部分，且该部分亚像素小于绿色亚像素的1/2面积。
针对位于偶数列的绿色亚像素，一并参考图9、图11及图12，由图9可以看出，位于偶数列的绿色亚像素位于交接区域22内，对位于遮挡矩形交接区域的亚像素进行显示时，以相邻列的亚像素组中位于所述遮挡矩形交接区域外且与该亚像素距离最近的一个用于显示同一视图且颜色一致的亚像素替代进行显示，具体的，在与位于遮挡矩形交接区域的亚像素相邻列的亚像素列中，寻找位于遮挡矩形交接区域外并与该亚像素显示同一视图且颜色一致的亚像素，并在找到的亚像素中，将与位于遮挡矩形交接区域的亚像素距离最近的一个亚像素作为替代亚像素，根据该替代亚像素的位置划分采样区，该采样区为矩形区域，且该矩形区域在列方向上的宽度介于亚像素在列方向宽度的 5～6倍之间，在行方向的宽度为亚像素在行方向宽度的2倍；且在列方向上，替代亚像素对应的采样区在上下端部均覆盖部分亚像素。
为了方便描述以S4C10绿色亚像素为例进行描述，若按照上述的采样区设计，则其对应的采样区如图11所示，其对应的采样区的四个顶点分别位于：S3R9亚像素内、S5R9亚像素内、S3R12亚像素内、S5R12亚像素内。但是该采样区内的亚像素由于受到光栅的遮挡，不能完全显示，因此，在本实施例中针对位于交接区域的亚像素，其对应的采样区域如图12所示，还以S4C10绿色亚像素为例进行描述。由图12可以看出，将S4C10位置的亚像素进行灭掉，即不进行显示，同时，需要通过S5R8进行显示以进行弥补，但是此时的S5R8的采样区和之前不能对应，因此，对S5R8的采样区重新进行设计，具体的，如图12所示，该矩形采样区的四个顶点分别位于：S4C6亚像素内、S6C6亚像素内、S4C11亚像素内及S6C11亚像素内。
一并参考图12及图13所示，其中，图12示出了以位于交接区域22的绿色亚像素右侧的一列亚像素组中的亚像素为替代像素12的例子，而图13示出了连续的四个位于交接区域22的绿色亚像素以左侧的一列亚像素组中的亚像素为替代像素12的例子。具体的，为了方便描述，以S4C10绿色亚像素为例，在图13中，其替代亚像素为S3R8绿色亚像素，其对应的采用区的四个顶点分别位于：S2C6亚像素内、S4C6亚像素内、S2C11亚像素内、S4C11亚像素内。
同理，一并参考图14及图15，图14示出了红色亚像素的分布示意图，由图14可以看出，奇数列的红色亚像素位于交接区域内，偶数列的红色亚像素位于交接区域外，对于偶数列的红色亚像素其采样区与上述蓝色亚像素及绿色亚像素的采样区设计相同，在此不再一一赘述。针对位于交接区域22的红色亚像素，其采样区设计如图15所示。对于位于交接区域的红色亚像素以位于其右侧一列亚像素中，距离最近的红色亚像素为替代像素12进行采样区设计，为了方便描述，以S5R3红色亚像素为例进行说明，其位于交接区域22中，在具体显示时，将S5R3红色亚像素灭掉，以S6C5红色亚像素代替，其对应的采样区的设计为矩形采样区，且该矩形采样区的四个顶点分别位于：S5C2亚像素、S7C2亚像素、S5C7亚像素、S7C7亚像素内。
本发明实施例还提供了一种3D显示装置的驱动装置，其在图17 的1702处示出，其被配置为执行上文所述的驱动方法。
本发明实施例还提供了一种3D显示系统，参见图17，其包括根据本发明实施例的3D显示装置1701及根据本发明实施例的其驱动装置1702。
通过上述描述可以看出，通过算法设计，灵活的控制亚像素11的开启点位置，及采样区对应3D视图信号的关系，利用这种虚拟显示和3D相结合的方法能够将插入视图的视觉分辨率提高。从而提高3D虚拟显示分辨率，增加3D显示效果。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。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。

    所述像素阵列包括：多列亚像素组，每列亚像素组包括M*N个亚像素，其中M为亚像素颜色种类，N为大于3的正整数；其中，每个亚像素为矩形形状，奇数列亚像素组和偶数列亚像素组错位设置；
    所述光栅包含多个以规则阵列排列的遮挡矩形，每个遮挡矩形用于遮挡列方向的至少一个亚像素；其中，相邻列中的遮挡矩形在列方向错位设置，相间一列的列中的遮挡矩形在行方向相对于它们之间的列对称设置。
  2. 如权利要求1所述的3D显示装置，其特征在于，所述奇数列亚像素组和偶数列亚像素组错位设置宽度为亚像素在列方向宽度的一半；
    所述相邻列中的遮挡矩形在列方向重叠设置的宽度为亚像素在列方向宽度的一半。
  3. 如权利要求1所述的3D显示装置，其特征在于，所述遮挡矩形在列方向的宽度与亚像素单元在列方向宽的7/2倍，在行方向的宽度为单个亚像素的宽度。
  4. 如权利要求1所述的3D显示装置，其特征在于，所述M的个数为3，所述亚像素颜色的为红色、绿色及蓝色。
  5. 如权利要求4所述的3D显示装置，其特征在于，所述像素阵列为三角形阵列。
  6. 如权利要求1～5任一项所述的3D显示装置，其特征在于，所述每列亚像素组中，从头开始依次每M个亚像素为一个视图单元，且相邻的视图单元对应3D显示中的不同视图。
  7. 一种3D显示装置的驱动方法，其特征在于，所述显示装置为权利要求1所述的显示装置；该方法包括：
    分别将待显示的3D视图的第一视图和第二视图划分为多个视图单元，并确定每一个视图单元中各个颜色的颜色分量；
    针对每一个视图的每一个亚像素，按照该亚像素对应的矩形采样区所覆盖的、属于该视图的各个视图单元中该亚像素的颜色的颜色分量确定该亚像素的发光亮度。
  8. 如权利要求7所述的驱动方法，其特征在于，对位于遮挡矩形在列方向重叠的区域的亚像素进行显示时，以相邻列的亚像素组中位于所述遮挡矩形在列方向重叠的区域外且与该亚像素距离最近的、用于显示同一视图且颜色一致的亚像素替代进行显示。
  9. 如权利要求7所述的驱动方法，其特征在于，对未位于遮挡矩形在列方向重叠的区域的亚像素进行显示时，所述采样区为矩形采样区，且该采样区域以对应的亚像素在列方向的中心线为该采样区域在列方向的中心线，该采样区域在行方向的宽度为亚像素在行方向宽度的2倍，在列方向上的宽度为亚像素在列方向宽度的3倍；
    其中：
    针对偶数列的亚像素，每个亚像素对应的采样区在列方向覆盖位于该采样区对应的亚像素下方的亚像素的一部分；
    针对奇数列的亚像素，每个亚像素对应的采样区在列方向上与偶数列的亚像素对应的采样区相接，且在行方向上与偶数列的亚像素对应的采样区位置相错。
  10. 如权利要求9所述的驱动方法，其特征在于，针对偶数列的亚像素，每个亚像素对应的采样区在列方向覆盖位于该采样区对应的亚像素下方的亚像素的部分介于0～1/2亚像素列方向的长度之间。
  11. 如权利要求8所述的驱动方法，其特征在于进一步包括：
    在与位于遮挡矩形在列方向重叠的区域的亚像素相邻列的亚像素列中，寻找位于遮挡矩形在列方向重叠的区域外并与该亚像素显示同一视图、且颜色相同的亚像素，并在找到的亚像素中，将与位于遮挡矩形在列方向重叠的区域的亚像素距离最近的一个亚像素作为替代亚像素，根据该替代亚像素的位置划分采样区，其为矩形区域，且该矩形区域在列方向上的宽度介于亚像素在列方向宽度的5～6倍之间，在行方向的宽度为亚像素在行方向宽度的2倍；且在列方向上，该替代亚像素对应的采样区在上下端部均覆盖部分亚像素。
  12. 一种3D显示装置的驱动装置，其特征在于，所述显示装置为权利要求1所述的显示装置；该驱动装置被配置来执行如权利要求7-11中任一个所述的方法。
  13. 一种3D显示系统，其包括根据权利要求1的3D显示装置及根据权利要求12的驱动装置。
