Description

显示屏及显示装置 技术领域
本申请涉及光学技术领域，例如涉及显示屏及显示装置。
背景技术
如图1所示，常见的视差屏障式裸眼3D显示屏结构，是在2D显示屏上设置视差屏障光栅1，在2D显示屏的像素排列结构中，通常把R子像素、G子像素和B子像素分别设计为矩形，且沿矩形的长边的延伸方向排列的子像素为相同颜色。
采用上述的像素排布结构的裸眼3D显示方案中，光栅轴线方向与矩形的长边的延伸方向的夹角α取锐角，通常小于26度。视点排列方向为矩形的短边的延伸方向。如图2所示，当左眼位置恰好与第三号子像素中心对应，右眼位置恰好与第六号子像素中心对应，此时的第二号子像素至第四号子像素显示左眼图像内容，第五号子像素至第七号子像素显示右眼图像内容，串扰最小。但当左右眼的对应位置发生偏移，如图3所示，左眼位置对应于第三号子像素与第四号子像素中间，右眼位置对应于第六号子像素和第七号子像素中间，此时的第五号子像素发出的光会同时进入左右眼，只要此处左眼图像和右眼图像的R通道灰阶值不一致，就无法同时满足左眼图像和右眼图像对R灰阶值的需求，一定会形成颜色串扰。并且由于在视点的排列方向上的像素颜色不同，用算法修正颜色串扰问题需要同时考虑三种不同颜色的灰阶值，不仅计算复杂、而且效果有限，限制了高动态3D显示的量产应用。

具体实施方式
为了能够更加详尽地了解本公开实施例的特点与技术内容，下面结合附图对本公开实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本公开实施例。在以下的技术描述中，为方便解释起见，通过多个细节以提供对所披露实施例的充分理解。然而，在没有这些细节的情况下，至少一个实施例仍然可以实施。在其它情况下，为简化附图，熟知的结构和装置可以简化展示。
如图4所示，本公开实施例提供了一种显示屏10，包括：多个复合像素101；
多个复合像素101中的每个复合像素101包括多个子像素106；
多个子像素106中的每个子像素106包括相对设置的短边和相对设置的长边，短边的长度短于长边的长度；
复合像素101中，沿短边延伸的方向排列的子像素106的颜色相同；
还包括设置于多个复合像素101之上的光栅102；光栅102包括多个沿S方向以周期长度D排列的单元103，周期长度D为光栅102的节距，沿单元103的长度的方向为T方向，其中，S方向与T方向垂直；T方向与短边延伸的方向之间的夹角为θ。
在一些实施例中，每个复合像素用于显示3D显示图像的一个完整像素，例如，当3D显示图像包含对应于左右眼的左眼图像和右眼图像时，每个复合像素对应显示左眼图像和右眼图像在同一像素坐标位置上的各一个像素。
在一些实施例中，如图4所示，平行于子像素短边延伸方向的一个方向为X方向，平行于子像素长边延伸方向的一个方向为Y方向。可选地，X方向为行方向，Y方向为列方向。可选地，复合像素101中，沿短边延伸的方向排列的子像素106的颜色相同。可选地，复合像素101中，沿长边延伸的方向排列的子像素106的颜色不同。可选地，沿X方向排列的子像素106的颜色相同，沿Y方向排列的子像素106的颜色不同。可选地，沿短边延伸的方向为视点排列的方向，即沿短边延伸方向，任意相邻的两个子像素分属于不同的视点。可选地，X方向为视点排列的方向。
在一些实施例中，如图4所示，点E、A、H、F圈出的虚线框表示一个复合像素101，显示屏10包括多行多列呈阵列形式排布的复合像素101。
在一些实施例中，每个复合像素101包括多行多列呈阵列形式排布的子像素106。在图4中，示例性地示出了复合像素101包括3行6列子像素106。但在实际应用中，可选地，复合像素101可以包括3行5列子像素106。可选地，复合像素101可以包括3行8列子像素106。可选地，复合像素101可以包括3行10列子像素106等等，本申请对此不作具体限定，只要是满足复合像素101在行方向上包括子像素106的个数(也称为i，或称为复合像素101中子像素106的列数)为大于或等于5的整数即可。
在一些实施例中，相邻两行复合像素101对齐。可选地，相邻两行的子像素106对齐。
在一些实施例中，复合像素101包括三行i列子像素106，i为大于或等于5的整数。可选地，i为选自6,7,8,9,10中的任意一个整数。可选地，位于行方向的子像素 106的颜色相同，位于列方向的子像素106的颜色不同。可选地，如图4所示，在一个复合像素101中，第一行子像素106的颜色可以为红色、绿色或蓝色中的其中一种颜色，第二行子像素106的颜色为与第一行子像素106的颜色不同且选自红色、绿色或蓝色中的一种颜色，第三行子像素106的颜色为与第一行子像素106的颜色和第二行子像素106的颜色均不同且选自红色、绿色或蓝色中的一种颜色。可选地，第一行子像素106的颜色为红色，第二行子像素106的颜色为绿色，第三行子像素106的颜色为蓝色。
在一些实施例中，D＝px*i*sinθ，以子像素106的短边延伸的方向为行方向，以子像素106的长边延伸的方向为列方向，在行方向上相邻的两个子像素106之间的中心距为px，在列方向上相邻的两个子像素106之间的中心距为py，i为在一个复合像素101中所包括的子像素106的列数。可选地，px＝20.9±0.1um。
在一些实施例中，T方向与短边延伸的方向之间的夹角为θ，取锐角。可选地，θ大于50°，且小于90°。可选地，θ大于74°，且小于86°。可选地，θ大于75°，且小于77°。可选地，θ大于83°，且小于86°。
在一些实施例中，复合像素101大致为正方形。可选地，px*i＝3*py。
本申请中，光栅102可以相对于复合像素101沿子像素短边延伸方向左右移动，光栅102移动到复合像素101的任意位置都在本申请的保护范围之内。
本申请中，通过使沿子像素短边延伸的方向排列的子像素106的颜色相同，使得视点的排列方向也是沿短边延伸方向，因此，在考虑一个复合像素内的一个子像素的基色如何显示时，只需要考虑一种基色即可。可选地，以复合像素内的任一一个红色子像素为例，决定任意一个红色子像素的显示灰阶时，只需要考虑红色这种基色，而不用考虑绿色和蓝色这两个基色造成影响，能够大大简化3D显示时的渲染计算，并且从结构上排除了不同基色的子像素之间的串扰，显著提高3D显示的图像质量。
如图5所示，可以看出左眼位置对应于第三号子像素106与第四号子像素106中间，右眼位置对应于第六号子像素106和第七号子像素106中间，虽然第五号子像素106发出的光会同时进入左右眼，但当考虑第五号子像素106应显示的灰阶值时，由于沿短边延伸方向排列的子像素106的颜色相同，故只要考虑对一种颜色的通道强度(R通道强度、G通道强度或B通道强度)做简单补偿即可，而不需要同时考虑三种通道颜色对第五号子像素106的影响，能够简化计算，并且去除串扰的效果显著。
在一些实施例中，光栅102设置于呈阵列形式排布的复合像素101之上。如图4所示，光栅102包括多个单元103，图4中示例性地示出了光栅102包括3个单元103。 可选地，光栅102的节距为D，即，单元103沿S方向的宽度为D，多个单元103以周期长度D沿S方向排列，沿单元103的长度延伸方向为T方向，S方向与T方向垂直。
在一些实施例中，光栅102可以包括柱透镜光栅102或狭缝光栅102，图4中以光栅102为柱透镜光栅102为例进行示例，可选地，光栅102还可以为狭缝光栅102。
在一些实施例中，继续如图4所示，当光栅102为柱透镜光栅102时，柱透镜光栅102包括多个沿S方向以周期长度D排列的柱透镜，柱透镜光栅102的节距为D，即，柱透镜沿S方向的宽度为D，柱透镜的轴线所在方向为T方向。
如图6所示，在一些实施例中，当光栅102为狭缝光栅102时，狭缝光栅102包括多个沿S方向以周期长度D排列的狭缝单元103，狭缝单元103包括遮光部104和透光部105，狭缝光栅102的节距为D，即，狭缝单元103沿S方向的宽度为D，沿透光部105的长度延伸的方向为T方向。可选地，遮光部104和透光部105沿S方向上的宽度可以相同，也可以不同，只要是二者之和为D即可。
在一些实施例中，显示屏10的3D分辨率为M×N，即显示屏10包括M×N个复合像素101，M大于N，其中，沿短边延伸的方向包括M个复合像素。可选地，沿长边延伸的方向包括N个复合像素。
在一些实施例中，如图4和7所示，子像素包括发光部分107和周围的非发光部分108。可选地，发光部分107可以为规则形状，如图4所示，发光部分为矩形。可选地，发光部分107可以为不规则形状，如图7所示，发光部分107为不规则四边形。可选地，发光部分107的形状可以相同也可以不同。可选地，子像素的形状为规则矩形，包括长边和短边。
如图8所示，本申请中的子像素是指，显示屏被完全划分为呈阵列排布且相同的多个矩形。可选地，每个矩形代表一个子像素。可选地，相邻的矩形共用一个边。可选地，相邻的矩形之间无间隙。可选地，子像素包括发光部分和周围的非发光部分。可选地，发光部分位于矩形中。可选地，矩形是人为进行划分的，实质上，只要是将显示屏完全划分为阵列排布的相同矩形，发光部分位于矩形中；且沿矩形的短边延伸的方向排列的子像素的颜色相同的显示屏都在本申请的保护范围之中。可选地，每个子像素包含的发光部分为一个可被独立驱动的最小发光单元。可选地，可被独立驱动的最小发光单元是指连接于同一个扫描线和同一个信号线的发光单元。可选地，如图9A所示，可被独立驱动的最小发光单元可以包含一个完整的发光区域。可选地，如图9B和图9C所示，可被独立驱动的最小发光单元可以包含两个或多个同步发光的区域。
如图9所示，本公开实施例还提供一种显示装置20，包括如上所述的任意一种显示屏10。
在一些实施例中，显示装置20还可以包括用于支持显示装置20正常运转的其他构件，例如：通信接口、框架、控制电路等构件中的至少之一。
