Description

像素结构、其驱动方法及显示装置 技术领域
本发明的实施例涉及一种像素结构、其驱动方法及显示装置。
背景技术
目前，显示屏常见的像素设计是RGB或RGBW设计，即由三个亚像素或四个亚像素组成一个像素进行显示，其视觉分辨率就是物理分辨率。但是随着客户对显示屏感受要求的增加，面板制作商需要不断增加显示屏的视觉分辨率(PPI)设计。目前，一般采用减小像素尺寸的方式来提高显示屏的物理分辨率。然而，随着像素的尺寸越来越小，制作显示屏的工艺难度会越来越大，尤其是在有机发光二极管(Organic Light Emitting Diode，OLED)显示屏的制作过程中，有机物的图形化工艺难度较大，在制作更高物理分辨率的显示屏上遇到了瓶颈。

根据本发明的又一个实施例提供了一种上述像素结构的驱动方法。

具体实施方式
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。
下面结合附图，对本发明实施例提供的像素结构、其驱动方法及显示装置的具体实施方式进行详细地说明。
本发明实施例提供了一种像素结构，如图1和图2所示，可以包括：多个紧密排列的重复组(图1和图2中虚线框标注处)；重复组由呈直线排列的RGB方形像素单元组成；在重复组中每个方形像素单元均由两个同一颜色且形状相同的亚像素组成，相邻的方形像素单元的两个亚像素的排列方式不同；位于相互平行且相邻的两条直线上的各重复组之间错开一个半方形像素单元的距离。
在上述实施例中，重复组由RGB方形像素单元组成，但根据本发明的实施例不限于此，例如，还可以包括其他颜色的方形像素单元。
例如，相邻的方形像素单元的两个亚像素的排列方式不同是指两个亚像素的排列方向不同，例如，两个亚像素可以沿行方向排列或列方向排列。
本发明实施例提供的上述像素结构，包括多个紧密排列的重复组；重复 组由呈直线排列的RGB方形像素单元组成；在重复组中每个方形像素单元均由两个亚像素组成，相邻的方形像素单元的两个同一颜色且形状相同的亚像素的排列方式不同；位于相互平行且相邻的两条直线上的各重复组之间错开一个半方形像素单元的距离，采用这样的异形像素排列的像素结构，配合虚拟计算实现虚拟显示。也就是说，通过实际物理位置对应输入信息，将输入信息进行亮度再分配，集中输出到实际物理位置。例如，在接收到显示一个白色像素的图像信号时，控制像素结构中显示白色像素的方形像素单元所在位置处呈品字形分布的三个相邻的RGB方形像素单元中的全部亚像素或相邻的三个RGB亚像素开启，以显示白色像素，这样在不减小像素尺寸的前提下灵活的运用亚像素的选择性开启，从而提高显示图像的输出分辨率。
本发明实施例提供的上述像素结构可以如图1所示的方式排列，即重复组中的RGB方形像素单元呈列排列，相邻列的重复组在行方向上错开一个半方形像素单元的距离，且在各重复组中，第一个方形像素单元和第三个方形像素单元中的两个亚像素在列方向上平行排列，第二个方形像素单元中的两个亚像素在行方向上平行排列，这样可以在物理空间上将RGB三种颜色的像素均匀分散排列。在进行图像显示时，能够使输入的图像信号对应物理像素的排列，将输入的信息进行亮度再分配，集中输出到实际物理像素的位置，进行虚拟显示输出，最终可以在不减小像素尺寸的前提下，提高显示图像的视觉分辨率。
例如，本发明实施例提供的上述像素结构在进行图像显示时，对应输入信息通过亮度比例计算获得实际输出信号，其对应实际物理像素输出的亮度分配可以如图3a所示。例如，R亚像素对应实际物理像素输出的亮度分配是中间的占用60％的亮度，上下各借用20％的亮度，从而进行亮度整体叠加获得实际输出亮度，当然亮度分配还可以以其他比例进行分配，如图3b-图3d所示，在此不作限定。
例如，本发明实施例提供的上述像素结构中，如图2所示，重复组中的RGB方形像素单元呈行排列；相邻行的重复组在行方向上错开一个半方形像素单元的距离，且在各重复组中，第一个方形像素单元和第三个方形像素单元中的两个亚像素在行方向上平行排列，第二个方形像素单元中的两个亚像素在列方向上平行排列，这样的像素排列方式同样可以在物理空间上将RGB 三种颜色的像素均匀分散排列。在进行图像显示时，能够使输入的图像信号对应物理像素的排列，将输入的信息进行亮度再分配，集中输出到实际物理像素的位置，进行虚拟显示输出，最终可以在不减小像素尺寸的前提下，提高显示图像的视觉分辨率。在进行图像显示时，对应输入信息通过亮度比例计算获得实际输出信号的方式与上述重复组中RGB方形像素单元呈列排列的像素结构相同，在此不作详述。
例如，在所述重复组中不同颜色的方形像素单元的排列方向上的多个重复组组成像素串；多个像素串被设置为各自延伸方向相互平行；分别位于相邻像素串中相邻的两个重复组在与像素串延伸方向垂直的方向上存在重叠，且重叠长度为所述重复组在不同颜色的方形像素单元的排列方向上长度的一半。如图1所示，所述重复组中不同颜色的方形像素单元的排列方向可以为列方向；如图2所述，所述重复组中不同颜色的方形像素单元的排列方向可以为行方向，但根据本发明的实施例不限于此。
例如，不同颜色的方形像素单元的形状和尺寸均相同。
例如，在每个方形像素单元中，亚像素的形状为矩形，但根据本发明的实施例不限于此。
本发明实施例提供了一种显示装置，包括本发明实施例提供的上述像素结构。该显示装置可以应用于手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。由于该显示装置解决问题的原理与像素结构相似，因此该显示装置的实施可以参见上述像素结构的实施，重复之处不再赘述。
本发明实施例提供了一种本发明实施例提供的上述像素结构的驱动方法，包括：在接收到显示至少一个白色像素的图像信号时，控制像素结构中显示白色像素的方形像素单元所在位置处呈品字形分布的三个相邻的RGB方形像素单元中的全部亚像素或相邻的三个RGB亚像素开启。
例如，本发明实施例提供的上述驱动方法中，在接收到显示一个白色像素时，对应如图4所示的输入信号，本发明实施例提供的像素结构对应的实际输出物理像素的位置可以如图5a或图5b所示。如图5a所示，对应输入信号实际输出蓝色的像素M7N3和M7N4的亮度是由图4中X12Y1、X12Y2、X12Y3按照一定亮度比例分配实现输出的，同理红色像素M7N5和M7N6 的亮度是由图4中X10Y2、X10Y3、X10Y4按照一定亮度比例分配实现输出的，绿色像素M9N4和M10N4的亮度是由图4中X14Y1、X14Y2、X14Y3按照一定亮度比例分配实现输出的；如图5b所示，在接收到显示一个白色像素时，也可以仅开启呈品字形分布的三个相邻的RGB方形像素单元中相邻的三个RGB亚像素，即公用输入的图像信号。在图5b中的红色亚像素M7N5进行实际输出时，输入的图像信号为图4中的X10Y2、X10Y3、X10Y4，其中以像素X10Y3为主要信息输出位置，亮度分配占主要权重，其他两个像素位置X10Y2和X10Y4的亮度分配则占次要权重，同理蓝色亚像素M7N4、绿色亚像素M9N4的信号输入和实际输出遵循相同的分配方式，在此不作详述，这样的组合输出方式能够在最小的物理空间内进行信号输出，这样可以实现虚拟显示，提高输出分辨率。
例如，本发明实施例提供的上述驱动方法中，在接收到显示包含一行白色像素的图像信号时，控制重复组中的RGB方形像素单元呈列排列的像素结构中，显示一行白色像素的方形像素单元所在位置处的各方形像素单元中部分亚像素开启，使开启的亚像素仅占用两行亚像素的位置。
例如，本发明实施例提供的上述驱动方法中，在接收到显示包含一行白色像素的图像信号时，如图6所示，将每个方形像素单元中的两个亚像素进行分别控制，仅开启需要开启的亚像素，不需要开启的亚像素则关闭，这样使得最后开启的亚像素能够在一条横线上表示最高分辨率。从而能够进行图像清晰化输出，使得图像虚拟分辨率更高。
例如，本发明实施例提供的上述驱动方法中，在接收到显示包含一列白色像素的图像信号时，控制重复组中的RGB方形像素单元呈行排列的像素结构中，显示一列白色像素的方形像素单元所在位置处的各方形像素单元中部分亚像素开启，使开启的亚像素仅占用两列亚像素的位置。
例如，本发明实施例提供的上述驱动方法中，在接收到显示包含一列白色像素的图像信号时，如图7所示，将每个方形像素单元中的两个亚像素进行分别控制，仅开启需要开启的亚像素，不需要开启的亚像素则关闭，这样使得最后开启的亚像素能够在一条竖线上表示最高分辨率。从而能够进行图像清晰化输出，使得图像虚拟分辨率更高。
例如，本发明实施例提供的上述驱动方法中，在接收到显示包含白色斜 线像素的图像信号时，控制像素结构中显示白色斜线像素的方形像素单元所在位置处的各方形像素单元中部分亚像素开启，使开启的亚像素连接成白色斜线像素的图像。
例如，本发明实施例提供的上述驱动方法中，在接收到显示包含白色斜线像素的图像信号时，如图8所示，将对应显示白色斜线像素图像信号的每个方形像素单元中的两个亚像素进行分别控制，仅开启需要开启的亚像素，不需要开启的亚像素则关闭，这样使得最后开启的亚像素能够沿着斜线图像的边界线进行开启，从而能够进行图像清晰化输出，使得图像虚拟分辨率更高。
例如，本发明实施例提供的上述驱动方法中，在接收到显示至少一个单色像素的图像信号时，控制像素结构中显示单色像素的方形像素单元所在位置处的方形像素单元中的全部亚像素或任一亚像素开启。
例如，本发明实施例提供的上述驱动方法中，在接收到显示单色像素例如红色像素的图像信号时，可以如图9a所示，将对应显示红色像素的方形像素单元中的两个红色亚像素同时开启，这样可以显示连续的图像；也可以如图9b和图9c所示，将对应显示红色像素的方形像素单元中的任一红色亚像素开启，这样在单个亚像素的开启上具有灵活性，可以显示精细画面的细节。
本发明实施例提供了一种像素结构、其驱动方法及显示装置，该像素结构包括：多个紧密排列的重复组；重复组由呈直线排列的RGB方形像素单元组成；在重复组中每个方形像素单元均由两个同一颜色且形状相同的亚像素组成，相邻的方形像素单元的两个亚像素的排列方式不同；位于相互平行且相邻的两条直线上的各重复组之间错开一个半方形像素单元的距离，采用这样的异形像素排列的像素结构，配合虚拟计算实现虚拟显示，即通过实际物理位置对应输入信息，将输入信息进行亮度再分配，集中输出到实际物理位置，例如，在接收到显示一个白色像素的图像信号时，控制像素结构中显示白色像素的方形像素单元所在位置处呈品字形分布的三个相邻的RGB方形像素单元中的全部亚像素或相邻的三个RGB亚像素开启，以显示白色像素，这样在不减小像素尺寸的前提下灵活的运用亚像素的选择性开启，从而提高显示图像的输出分辨率。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范 围，本发明的保护范围由所附的权利要求确定。
本申请要求于2015年4月9日递交的中国专利申请第201510166850.3号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
