Description

像素结构、显示基板和显示装置
本申请要求于2015年4月24日递交的中国专利申请第201510203146.0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。
技术领域
本发明的示例性实施例涉及一种像素结构、显示基板和显示装置。
背景技术
随着显示技术的发展，人们对视觉效果的追求越来越高，所以高PPI(单位面积像素数)的显示产品成为显示器厂商关注的焦点。
传统的显示基板中，像素结构采用RGB(红绿蓝)子像素循环排列的方式，其中每个像素的面积相同，并由横向排列的红、绿、蓝子像素构成，每个子像素的面积相同，具体如图1所示。采用这种像素结构的显示基板在显示图像时，视觉分辨率与物理分辨率相同。
通过子像素渲染法来驱动子像素时，可以实现视觉分辨率大于物理分辨率。在显示三角形时，点亮的像素排列如图2所示，其中蓝色子像素和红色子像素的数量之和等于绿色子像素的数量，在点亮的像素和未点亮的像素之间，从右上到左下以红色子像素为主，而在显示直线时，也会存在显示边界以红、蓝、红、蓝子像素竖直交替排列，或者以单一绿色子像素竖直排列的情况，在视觉上显示为彩色勾边，从而影响显示效果。
发明内容
本发明旨在提供一种像素结构以及相应的显示基板和显示装置，以便在提高视觉分辨率的同时，减少图像显示时出现的勾边现象。
根据本发明的第一方面，提出了一种像素结构，包括：
多个第一像素、第二像素和第三像素，
所述第一像素包括位于右上方的第一子像素和位于左下方的第二子像素，
所述第二像素包括位于右上方的第二子像素和位于左下方的第三子像素，以及
所述第三像素包括位于右上方的第三子像素和位于左下方的第一子像素，
所述第一像素的右方和上方设置有所述第二像素，所述第二像素的右方和上方设置有所述第三像素，以及所述第三像素的右方和上方设置有所述第一像素。
根据本发明的实施例，所述第一子像素、第二子像素和第三子像素为直角三角形，
所述第一像素中的第一子像素和第二子像素的斜边相对应，
所述第二像素中的第二子像素和第三子像素的斜边相对应，以及
所述第三像素中的第三子像素和第一子像素的斜边相对应。
根据本发明的实施例，所述直角三角形为等腰直角三角形。
根据本发明的实施例，所述第一子像素、第二子像素以及第三子像素各不相同，并分别对应红色子像素、绿色子像素和蓝色子像素中的一个。根据本发明的实施例，目标像素的相邻像素为与所述目标像素中的子像素存在对应直角边的子像素。
根据本发明的实施例，绿色子像素占所述第一像素、第二像素以及第三像素总面积的1/2以上。
根据本发明的第二方面，提出了一种像素结构，包括：
多个第一像素、第二像素和第三像素，
所述第一像素包括位于左上方的第一子像素和位于右下方的第二子像素，
所述第二像素包括位于左上方的第三子像素和位于右下方的第一子像素，以及
所述第三像素包括位于左上方的第二子像素和位于右下方的第三子像 素，
所述第一像素的右方和下方设置有所述第二像素，所述第二像素的右方和下方设置有所述第三像素，以及所述第三像素的右方和下方设置有所述第一像素。
根据本发明的实施例，所述第一子像素、第二子像素和第三子像素为直角三角形，
所述第一像素中的第一子像素和第二子像素的斜边相对应，
所述第二像素中的第三子像素和第一子像素的斜边相对应，以及
所述第三像素中的第二子像素和第三子像素的斜边相对应。
根据本发明的实施例，所述直角三角形为等腰直角三角形。
根据本发明的实施例，所述第一子像素、第二子像素以及第三子像素各不相同，并分别对应红色子像素、绿色子像素和蓝色子像素中的一个。

根据本发明的第三方面，还提出了一种显示基板，包括上述任一项所述的像素结构。
根据本发明的第四方面，还提出了一种显示装置，包括上述的显示基板。
根据本发明的实施例，由于每个像素包括两个子像素，在通过子像素渲染法驱动时，可以借用相邻像素中的子像素，从而提高子像素的单位面积的像素数(PPI)，并且在显示具有斜向边界、横向边界和/或竖向边界的图像时，由于图像的边界以第一子像素、第二子像素和第三子像素三种像素交错排列，不会出现彩色勾边的现象。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动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。
在本发明的描述中，需要说明的是，术语“上”、“下”、“顶”、“底” 等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，在本发明中，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。术语“多个”指两个或两个以上，除非另有明确的限定。
实施例一
如图3和图4所示，根据本发明一个实施例的像素结构，包括：
多个第一像素、第二像素和第三像素，
第一像素包括位于右上方的第一子像素(即红色子像素)和位于左下方的第二子像素(即绿色子像素)，
第二像素包括位于右上方的第二子像素(即绿色子像素)和位于左下方的第三子像素(即蓝色子像素)，以及
第三像素包括位于右上方的第三子像素(即蓝色子像素)和位于左下方的第一子像素(即红色子像素)，
第一像素的右方和上方设置有第二像素，第二像素的右方和上方设置有第三像素，以及第三像素的右方和上方设置有第一像素。
由于每个像素包括两个子像素，像素结构中每种子像素的数量相等，在通过子像素渲染法驱动时，可以借用相邻像素中的子像素。如图5所示，现有技术像素结构中设置的第一采样区，与图6中在实施例一所示的像素结构中设置的第二采样区相对应，其中，在如图5所示的像素结构中，每个像素包含3个子像素，当显示四乘四个的像素的图像时，需要点亮3×4×4＝48个子像素，而在如图6所示的像素结构中，当显示四乘四的像素的图像时，需要点亮2×4×4＝32个子像素，即图6中的像素结构的分辨率为图5中的像素结构的分辨率的1.5倍(48/32)，显示相同数目的像素阵列时，可以减少1/3子像素的使用，从而提高子像素的单位面积的像素数(PPI)。
具体地，根据本实施例的像素结构显示横线时点亮的像素结构如图7 所示，每条横线中第一子像素、第二子像素和第三子像素三种像素交错排列；根据本实施例的像素结构显示竖线时点亮的像素结构如图8所示，每条竖线的第一子像素、第二子像素和第三子像素三种像素交错排列；根据本实施例的像素结构显示图像存在45°分界时点亮的像素结构如图9所示，分界线上第一子像素、第二子像素和第三子像素三种像素交错排列。
由此可见，根据本发明的实施例排列的像素结构，在显示具有斜向边界、横向边界和/或竖向边界的图像时，图像的边界均以第一子像素、第二子像素和第三子像素三种像素交错排列，不会出现彩色勾边的现象，从而提高用户的观看效果。
根据本发明的实施例，第一子像素、第二子像素和第三子像素为直角三角形，
第一像素中的第一子像素和第二子像素的斜边相对应(即红色子像素和绿色子像素的斜边重叠)，
第二像素中的第二子像素和第三子像素的斜边相对应(即绿色子像素和蓝色子像素的斜边重叠)，以及
第三像素中的第三子像素和第一子像素的斜边相对应(即蓝色子像素和红色子像素的斜边重叠)。
根据本实施例的像素结构显示图像时，由于每个像素中的两个直角三角形子像素的斜边相对应(例如，斜边重叠)，即每个像素中的两个子像素可构成一个矩形，从而在显示横线和/或竖线时，横线和/或竖线的边界为整齐的直线，不会在边界出现锯齿。
根据本发明的实施例，直角三角形可以为等腰直角三角形。等腰直角三角形的面积利用率相对于普通的直角三角形面积利用率较高，可以合理布设像素，充分利用显示屏的面积。
根据本发明的实施例，第一子像素为红色子像素，第二子像素为绿色子像素，第三子像素为蓝色子像素，该实施例对应图3所示的像素结构。
根据本发明的另一实施例，第一子像素为绿色子像素，第二子像素为红色子像素，第三子像素为蓝色子像素，该实施例对应图10所示的像素结 构。
根据本发明的又一实施例，绿色子像素可以占像素总面积的1/2以上(即大于或者等于1/2)，由于绿色子像素的亮度相对于红色子像素和蓝色子像素较高，因此，提高像素中绿色子像素的比例可以有效提高基板的整体显示亮度。
根据本发明的实施例，在点亮目标像素时，点亮的目标像素的相邻像素为与目标像素中的子像素存在对应直角边(即存在重叠的直角边)的子像素。通过子像素渲染法驱动子像素，可以使得点亮的像素从其相邻像素中借用该像素缺少的子像素，从而实现完整的色域显示。
实施例二
如图11所示，根据本发明的又一个实施例的像素结构，包括：
多个第一像素、第二像素和第三像素，
第一像素包括位于左上方的第一子像素(即红色子像素)和位于右下方的第二子像素(即绿色子像素)，
第二像素包括位于左上方的第三子像素(即蓝色子像素)和位于右下方的第一子像素(即红色子像素)，以及
第三像素包括位于左上方的第二子像素(即绿色子像素)和位于右下方的第三子像素(即蓝色子像素)，
第一像素的右方和下方设置有第二像素，第二像素的右方和下方设置有第三像素，以及第三像素的右方和下方设置有第一像素。
根据本发明的实施例，第一子像素、第二子像素和第三子像素可以为直角三角形。
第一像素中的第一子像素和第二子像素的斜边相对应(即红色子像素和绿色子像素的斜边重叠)，
第二像素中的第三子像素和第一子像素的斜边相对应(即蓝色子像素和红色子像素的斜边重叠)，以及
第三像素中的第二子像素和第三子像素的斜边相对应(即绿色子像素和蓝色子像素的斜边重叠)。
根据本发明的实施例，直角三角形可以为等腰直角三角形。
根据本发明的实施例，第一子像素为红色子像素，第二子像素为绿色子像素，第三子像素为蓝色子像素，该实施例对应图11所示的像素结构。
根据本发明的另一实施例，所述第一子像素为绿色子像素，所述第二子像素为红色子像素，所述第三子像素为蓝色子像素，该实施例对应图12所示的像素结构。
根据本发明的实施例，在点亮目标像素时，点亮目标像素的相邻像素为与目标像素中的子像素存在对应直角边(即存在重叠直角边)的子像素。
与实施例一中类似地，实施例二中的像素结构，在显示具有斜向边界、横向边界和/或竖向边界的图像时，图像的边界为第一子像素、第二子像素和第三子像素三种像素交错排列，不会出现彩色勾边的现象，从而提高用户的观看效果。
根据本发明的实施例，还提出了一种显示基板，包括上述实施例一中的像素结构，和/或上述实施例二中的像素结构。
根据本发明的实施例，还提出了一种显示装置，包括上述的显示基板。
需要说明的是，本实施例中的显示装置可以为：电子纸、手机、平板电脑、电视机、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。
以上结合附图详细说明了本发明的技术方案，考虑到现有技术中，通过子像素渲染法驱动的像素结构，在显示图像时容易出现彩色勾边。根据本发明的实施例，在显示具有斜向边界、横向边界和/或竖向边界的图像时，图像的边界为第一子像素、第二子像素和第三子像素三种像素交错排列，不会出现彩色勾边的现象。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
