Description

组合式显示面板 技术领域
本申请涉及电子显示领域，尤其涉及一种组合式显示面板。
 背景技术
现有的裸眼3D技术主要包括光屏障技术和柱状透镜技术。
光屏障式技术的原理是利用液晶层和偏振膜制造出一系列方向为90°的垂直条纹。这些条纹宽几十微米，通过它们的光就形成了垂直的细条光栅。所述细条光栅能够将进入左眼和右眼的可视画面分开，使用户看到3D影像。光屏障式技术的优点是成本低，易于量产。
柱状透镜技术也被称为微柱透镜3D技术，即在液晶显示屏幕前加装一排柱状的透镜，使液晶屏的像平面位于透镜的焦平面上。同时在每个柱透镜下面的图像的像素被分成几个子像素，透镜以不同的方向投影每个子像素。由于用户的双眼观看显示屏的角度不同，因此进入用户左眼和右眼的可视画面被分开，使用户看到3D影像。
 技术问题
使用光屏障式技术获得的3D画面分辨率和亮度都比较低，用户体验较差。柱状透镜技术能够优化屏幕亮度，比光屏障式技术获得的3D影像的显示效果要好。但是透镜的应用会使得画面产生一定的变形，且无法提高3D影像的分辨率。
 技术解决方案
本申请提供了一种组合式显示面板，以提高裸眼3D显示的分辨率和亮度。
为解决上述问题，本申请提供了一种组合式显示面板，所述组合式显示面板包括N个子显示屏，所述N个子显示屏重叠设置，其中，N为大于等于2的正整数；其中，

本申请提供了一种组合式显示面板，以提高裸眼3D显示的分辨率和亮度。下面将结合附图对本申请进行详细说明。
本申请提供了一种组合式显示面板，所述组合式显示面板包括N个子显示屏，所述N个子显示屏重叠设置，其中，N为大于等于2的正整数；其中，每一个所述子显示屏包括多个子显示单元，任意两个子显示屏中的多个子显示单元在所述组合式显示面板的出光面上的投影重合，同一组对应设置的多个子显示单元构成所述组合式显示面板的一个显示单元；每一个所述显示单元中的每一个子显示单元包含一个像素区和一个透光区，且所述多个子显示单元中的多个像素区在所述组合式显示面板的出光面上的投影完全覆盖所述显示单元的出光面。
图1、图2和图3示出了本申请的第一个实施例，其中，图1为本实施例中的第一子显示屏的结构示意图，图2为本实施例中的第二子显示屏的结构示意图，图3为由图1和图2中的第一子显示屏和第二子显示屏构成的组合式显示面板的结构示意图。
本实施例中，N等于2，所述显示面板包括第一子显示屏D1和第二子显示屏D2。所述第一子显示屏D1和第二子显示屏D2均包括多个子显示单元，所述第一子显示屏D1的多个子显示单元和第二子显示屏D2的多个子显示单元在所述组合式显示面板的出光面上的投影重合。同一组对应设置的多个子显示单元构成所述组合式显示面板的一个显示单元。所述第一子显示屏D1点每一个子显示单元包含一个像素区111和一个透光区112，所述第二子显示屏D2点每一个子显示单元包含一个像素区121和一个透光区122，且所述第一子显示屏D1的像素区111和第二子显示屏D2的像素区121在所述组合式显示面板的出光面上的投影完全覆盖所述显示单元的出光面。
本实施例中，第一子显示屏D1的像素区111和第二子显示屏D2的像素区121在所述组合式显示面板的出光面上的投影不重叠。所述像素区111和像素区121的面积相等且等于所述显示子单元的面积的1/2。
本实施例中，所述两个子显示屏具有相同的面积、形状和厚度，所述两个子显示屏在所述组合式显示面板的出光面上的投影完全重叠。重叠之后，第一子显示屏D1的像素区111和第二子显示屏D2的像素区121在所述组合式显示面板的出光面上的投影完全覆盖所述显示单元，第二子显示屏D2的像素区121发出的光线能够通过第一子显示屏D1的透光区112到达所述组合式显示面板的出光面。由于第一子显示屏D1和第二子显示屏D2之间具有固定的间隔，因此第一子显示屏D1的显示画面和第二子显示屏D2的显示画面之间存在一定的景深，不需要分割画面即可实现3D显示。
本申请中，每一个像素区包括至少一个红色像素点P1、至少一个绿光像素点P2和至少一个蓝光像素点P3。对于面积相同的显示面板，像素区包含的像素点的数目越小，显示单元的数目越多，第一子显示屏D1和第二子显示屏D2对画面的分离就越精确，3D效果越好。因此，本实施例中，每一个像素区包括一个红色像素点P1、一个绿光像素点P2和一个蓝光像素点P3。
本申请中，所述组合式显示面板还包括画面处理器和信号传输单元。所述画面处理器根据画面内容将要显示的画面切分为两个位面，使景深处于同一范围的显示对象显示在同一块子显示屏上。所述信号传输单元包括两个子传输单元，所述两个子传输单元与所述两个子显示屏一一对应，每一个子传输单元根据画面处理器的指令将待显示的对象的信息传送到相应的子显示屏上。画面中的对象与所述组合式显示面板的出光面之间的距离与所述对象的景深成正比。
在本实施例中，所述画面处理器根据画面内容将要显示的画面切分为两个位面，使景深较小的显示对象显示在第一子显示屏D1上，景深较大的显示对象显示在第二子显示屏D2上。第二子显示屏D2上的画面穿过所述第一子显示屏D1的透光区从实施组合式显示面板的出光面射出。由于实施第一子显示屏D1和第二子显示屏D2之间具有固定距离的间隔，实施组合式显示面板显示的画面自然的具有景深效果，不需要对显示面板的光线进行处理即可获得3D效果。相比于现有技术中的裸眼3D技术，本申请避免了光线损失和画面变形，显示效果好。
图4至图8示出了本申请的第二个实施例，其中，图4为本实施例中的第一子显示屏的结构示意图，图5为本实施例中的第二子显示屏的结构示意图，图6为本实施例中的第三子显示屏的结构示意图，图7为本实施例中的第四子显示屏的结构示意图，图8为由图4至图7中的第一子显示屏、第二子显示屏、第三子显示屏和第四子显示屏构成的组合式显示面板的结构示意图。
本实施例中，N等于4，所述显示面板包括第一子显示屏D1、第二子显示屏D2、第三子显示屏D3和第四子显示屏D4。所述第一子显示屏D1、第二子显示屏D2、第三子显示屏D3和第四子显示屏D4均包括多个子显示单元，所述第一子显示屏D1的多个子显示单元、第二子显示屏D2的多个子显示单元、第三子显示屏D3的多个子显示单元和第四子显示屏D4的多个子显示单元在所述组合式显示面板的出光面上的投影重合。同一组对应设置的多个子显示单元构成所述组合式显示面板的一个显示单元。每一个子显示单元包含一个像素区和一个透光区，且所述第一子显示屏D1的像素区211、第二子显示屏D2的像素区212、第三子显示屏D3的像素区213和第四子显示屏D4的像素区214在所述组合式显示面板的出光面上的投影完全覆盖所述显示单元的出光面。
本实施例中，第一子显示屏D1的像素区211、第二子显示屏D2的像素区212、第三子显示屏D3的像素区213和第四子显示屏D4的像素区214在所述组合式显示面板的出光面上的投影不重叠。所述像素区211、像素区212、像素区213和像素区214的面积相等且等于所述显示子单元的面积的1/4。所述像素区之外的区域为透光区。
本实施例中，所述第一子显示屏D1的透光区包括第一透光区221、第二透光区231、第三透光区241。所述第一透光区221、第二透光区231、第三透光区241分别对应第二子显示屏D2的像素区212、第三子显示屏D3的像素区213和第四子显示屏D4的像素区214。
本实施例中，所述第二子显示屏D2的透光区包括第一透光区222、第二透光区232、第三透光区242。所述第一透光区222、第二透光区232、第三透光区242分别对应第一子显示屏D1的像素区211、第三子显示屏D3的像素区213和第四子显示屏D4的像素区214。第二子显示屏D2的像素区212发出的光线能够通过第一子显示屏D1的透光区到达所述组合式显示面板的出光面。
本实施例中，所述第三子显示屏D3的透光区包括第一透光区223、第二透光区233、第三透光区243。第一透光区223、第二透光区233、第三透光区243分别对应第一子显示屏D1的像素区211、第二子显示屏D2的像素区212和第四子显示屏D4的像素区214。第三子显示屏D3的像素区213发出的光线能够通过第一子显示屏D1和第二子显示屏D2的透光区到达所述组合式显示面板的出光面。
本实施例中，所述第四子显示屏D4的透光区包括第一透光区224、第二透光区234、第三透光区244。第一透光区224、第二透光区234、第三透光区244分别对应第一子显示屏D1的像素区211、第二子显示屏D2的像素区212和第三子显示屏D3的像素区213。第四子显示屏D4的像素区214发出的光线能够通过第一子显示屏D1、第二子显示屏D2和第三子显示屏D3的透光区到达所述组合式显示面板的出光面。
本实施例中，所述第一子显示屏D1、第二子显示屏D2、第三子显示屏D3和第四子显示屏D4具有相同的面积、形状和厚度，所述四个子显示屏在所述组合式显示面板的出光面上的投影完全重叠。重叠之后，所述第一子显示屏D1的像素区211、第二子显示屏D2的像素区212、第三子显示屏D3的像素区213和第四子显示屏D4的像素区214在所述组合式显示面板的出光面上的投影完全覆盖所述显示单元。
由于第一子显示屏D1、第二子显示屏D2、第三子显示屏D3和第四子显示屏D4之间具有固定的间隔，因此第一子显示屏D1的显示画面和第二子显示屏D2的显示画面之间存在一定的景深，不需要分割画面即可实现3D显示。本实施例中，所述第一子显示屏D1、第二子显示屏D2、第三子显示屏D3和第四子显示屏D4之间的间隔相等。
本申请中，每一个像素区包括至少一个红色像素点P1、至少一个绿光像素点P2和至少一个蓝光像素点P3。对于面积相同的显示面板，像素区包含的像素点的数目越小，显示单元的数目越多，第一子显示屏D1和第二子显示屏D2对画面的分离就越精确，3D效果越好。因此，本实施例中，每一个像素区包括一个红色像素点P1、一个绿光像素点P2和一个蓝光像素点P3。
本申请中，所述组合式显示面板还包括画面处理器和信号传输单元。所述画面处理器根据画面内容将要显示的画面切分为四个位面，使景深处于同一范围的显示对象显示在同一块子显示屏上。所述信号传输单元包括四个子传输单元，所述四个子传输单元与所述四个子显示屏一一对应，每一个子传输单元根据画面处理器的指令将待显示的对象的信息传送到相应的子显示屏上。画面中的对象与所述组合式显示面板的出光面之间的距离与所述对象的景深成正比。
在本实施例中，所述画面处理器根据画面内容将要显示的画面切分为四个位面，使景深最小的显示对象显示在第一子显示屏D1上，使景深较小的显示对象显示在第二子显示屏D2上，景深较大的显示对象显示在第三子显示屏D3上，景深最大的显示对象显示在第四子显示屏D4上。由于第一子显示屏D1、第二子显示屏D2、第三子显示屏D3和第四子显示屏D4之间具有固定的间隔，因此第一子显示屏D1的显示画面和第二子显示屏D2的显示画面之间存在一定的景深，不需要对显示面板的光线进行处理即可获得3D效果。相比于现有技术中的裸眼3D技术，本申请避免了光线损失和画面变形，显示效果好。
需要说明的是，本申请中的子显示屏的数目不限于上述实施例中说明的两个或四个，也可以是三个、五个或更多。上述实施例仅用于说明本申请，不能理解为对本申请的限制。
本申请提供的组合式显示面板具有多个重叠设置的子显示屏，所述组合式显示面板的显示单元由多个对应设置的子显示屏中的像素区彼此互补构成。由于同一个显示单元中的像素区分别设置在不同的显示子显示屏上，因此本申请中的组合式显示面板所显示的画面自带一定的景深效果。通过将要显示的对象按照景深的范围分别投射在不同的子显示屏上即可实现三维显示。相比于现有技术中的裸眼3D技术，本申请不需要对显示面板的显示画面进行分割即可实现3D显示，同时避免了光线损失和画面变形，显示效果好。
综上所述，虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
