为使本领域的技术人员更好地理解本发明的技术方案， 下面结合附 图对本发明提供的显示基板和显示装置进行详细描述。
图 2为本发明的实施例一提供的一种显示基板的结构示意图，如图 2 所示， 该显示基板包括： 衬底基板和形成于衬底基板之上的重复排列的多 个像素组， 每个像素组包括四个第一子像素 21、 四个第二子像素 22、 四 个第三子像素 23和四个第四子像素 24， 每个像素组中的子像素以 4 X 4 矩阵排列，每个像素组中的每行子像素包括一个第一子像素 21、一个第二 子像素 22、一个第三子像素 23和一个第四子像素 24。 在一个像素组的四 行子像素中， 其中一行子像素中第一子像素 21、 第二子像素 22、 第三子 像素 23和第四子像素 24依次排列，其中一行子像素中第二子像素 22、第 三子像素 23、第四子像素 24和第一子像素 21依次排列，其中一行子像素 中第四子像素 24、 第一子像素 21、 第二子像素 22和第三子像素 23依次 排列， 其中一行子像素中第四子像素 24、 第一子像素 21、 第二子像素 22 和第三子像素 23依次排列，第一子像素 21、第二子像素 22和第三子像素 23中的至少一个中设置有白色透光区域 2， 第四子像素 24为白色子像素。
本实施例中， 第一行子像素中第一子像素 21、 第二子像素 22、 第三 子像素 23和第四子像素 24依次排列，第二行子像素中第二子像素 22、第 三子像素 23、第四子像素 24和第一子像素 21依次排列，第三行子像素中 第四子像素 24、 第一子像素 21、 第二子像素 22和第三子像素 23依次排 列， 第四行子像素中第三子像素 23、 第四子像素 24、 第一子像素 21和第 二子像素 22依次排列。
具体地， 第一子像素 21为红色子像素， 第二子像素 22为绿色子像 素， 第三子像素 23为蓝色子像素。 则在一个像素组中， 第一行子像素中 红色子像素、 绿色子像素、 蓝色子像素和白色子像素依次排列， 第二行子 像素中绿色子像素、 蓝色子像素、 白色子像素和红色子像素依次排列， 第 三行子像素中白色子像素、 红色子像素、 绿色子像素和蓝色子像素依次排 列， 第四行子像素中蓝色子像素、 白色子像素、 红色子像素和绿色子像素 依次排列。
本实施例中， 红色子像素、 绿色子像素和蓝色子像素的透过率低于 30%, 而白色透光区域 2的透过率接近 100%， 因此在红色子像素、 绿色子 像素和蓝色子像素中的至少一个中设置有白色透光区域 2， 从而可有效提 高显示基板的透过率。
每行子像素中， 第一子像素 21、 第二子像素 22、 第三子像素 23和 第四子像素 24 中的四个子像素或者其中的任意两个子像素形成一个像素 单元。 本实施例中， 每行子像素中， 第一子像素 21、 第二子像素 22、 第 三子像素 23和第四子像素 24中的两个子像素形成一个像素单元。若第一 子像素 21为红色子像素、 第二子像素 22为绿色子像素、 第三子像素 23 为蓝色子像素， 第一行子像素中像素单元 3包括依次排列的红色子像素和 绿色子像素， 第一行子像素中像素单元 4包括依次排列的蓝色子像素和白 色子像素， 第二行子像素中像素单元 3包括依次排列的绿色子像素和蓝色 子像素，第二行子像素中像素单元 4包括依次排列的白色子像素和红色子 像素， 第三行子像素中像素单元 3包括依次排列的白色子像素和红色子像 素，第三行子像素中像素单元 4包括依次排列的绿色子像素和蓝色子像素， 第四行子像素中像素单元 3包括依次排列的蓝色子像素和白色子像素， 第 四行子像素中像素单元 4包括依次排列的红色子像素和绿色子像素。
本实施例中， 若第一子像素 21、 第二子像素 22、 第三子像素 23和 第四子像素 24 中的任意两个子像素形成一个像素单元， 则未包括第四子 像素 24的像素单元中的至少一个子像素中设置有白色透光区域 2。 例如， 未包括第四子像素 24的像素单元中的第一子像素 21和 /或第三子像素 23 中设置有白色透光区域 2。 若第一子像素 21 为红色子像素、 第二子像素 22为绿色子像素、 第三子像素 23为蓝色子像素， 例如， 如图 2所示， 第 一行子像素的第一像素单元 3包括红色子像素和绿色子像素， 该第一行子 像素的第一像素单元 3未包括白色子像素， 则该第一像素单元 3中的红色 子像素中设置有白色透光区域 2 ; 第一行子像素的第二像素单元 4包括蓝 色子像素和白色子像素， 则该第二像素单元 4中的蓝色子像素中无需设置 白色透光区域 2 ; 第二行子像素的第一像素单元 3包括绿色子像素和蓝色 子像素， 该第二行子像素的第一像素单元 3未包括白色子像素， 则该第一 像素单元 3中的蓝色子像素中设置有白色透光区域 2 ; 第二行子像素的第 二像素单元 4包括白色子像素和红色子像素， 则该第二像素单元 4中的红 色子像素中无需设置白色透光区域 2 ; 第三行子像素的第一像素单元 3包 括白色子像素和红色子像素， 则该第一像素单元 3中的红色子像素中无需 设置白色透光区域 2 ; 第三行子像素的第二像素单元 4包括绿色子像素和 蓝色子像素， 该第三行子像素的第二像素单元 4未包括白色子像素， 则该 第二像素单元 4中的蓝色子像素 23中设置有白色透光区域 2 ;第四行子像 素的第一像素单元 3包括蓝色子像素和白色子像素， 则该第一像素单元 3 中的蓝色子像素中无需设置白色透光区域 2 ; 第四行子像素的第二像素单 元 4包括红色子像素和绿色子像素， 该第四行子像素的第二像素单元 4未 包括白色子像素， 则该第二像素单元 4的红色子像素中设置有白色透光区 域 2。 上述方案中， 每个像素单元中均包括了白色子像素或者白色透光区 域， 并且每个像素单元中均包括了红、 绿、 蓝三种颜色元素， 从而提高了 显示画面的显示效果。 上述方案中， 设置白色透光区域使得白色分布更加 均匀，从而在提高显示基板的透过率的同时，提高了显示画面的显示效果， 进而优化了用户的视觉体验。 相对于绿色子像素， 人眼对红色子像素和蓝 色子像素的敏感度更低， 因此在红色子像素和蓝色子像素中设置白色透光 区域， 可在提高显示基板的透过率的同时确保显示画面的显示品质。
本实施例中， 白色透光区域 2 为镂空区域。 本实施例中， 白色透光 区域 2的形状为条状， 可选地， 在实际应用中， 该白色透光区域 2还可以 为其它形状。 本实施例中， 该白色透光区域 2横向设置， 可选地， 在实际 应用中， 该白色透光区域 2还可以采用其它形式设置， 例如， 该白色透光 区域 2可以斜向设置。
本实施例中， 在垂直于第一子像素 21、第二子像素 22和第三子像素
23的排列方向的方向上， 例如， 在列方向上， 白色透光区域 2的尺寸小于 或等于第一子像素 21、第二子像素 22或第三子像素 23的尺寸的 1/3且大 于 0。
可选地， 该显示基板还可以包括： 黑矩阵 1， 该黑矩阵 1形成于衬底 基板上， 将各子像素隔开。
作为一种可选方案， 全部第一子像素 21、第二子像素 22和第三子像 素 23中均设置有白色透光区域 2，此种情况不再具体示出。作为一种可选 方案，全部或者部分第二子像素 22中设置有白色透光区域 2， 此种情况不 再具体示出。作为一种可选方案， 全部或者部分第一子像素 21、第二子像 素 22和第三子像素 23中的任意两种中设置有白色透光区域 2， 此种情况 不再具体示出。 在实际应用中， 还可以根据色彩配比的需求设置白色透光 区域的数量以及位置， 以达到提高显示基板的透过率以及确保显示画面的 显示品质的目的， 此处不再一一列举。
实际显示过程中， 通过对原有的红色子像素对应的红色亮度信号、 绿色子像素对应的绿色亮度信号和蓝色子像素对应的蓝色亮度信号进行 处理， 例如根据白色透光区域所占子像素的面积的比例而适当增加或降低 提供给该子像素的电压信号， 使得该子像素的灰阶得到增加或降低， 可使 得设置有白色透光区域的各个红色子像素、绿色子像素和蓝色子像素的色 域更广。
本实施例提供的显示基板的技术方案中， 衬底基板上形成有重复排 列的多个像素组， 每个像素组包括四个第一子像素、 四个第二子像素、 四 个第三子像素和四个第四子像素， 其中， 除了作为白色子像素的第四子像 素之外， 第一子像素、 第二子像素和第三子像素中的至少一个中设置有白 色透光区域， 有效地提高了显示基板的透过率， 从而提高了显示装置的透 过率。 由于本实施例可提高显示装置的透过率， 因此在本实施例的显示装 置的整体亮度与现有技术的显示装置的整体亮度保持一致的前提下， 可降 低背光源的发光亮度。本实施例中，仅部分子像素中设置有白色透光区域， 避免了白色透光区域在行方向上形成连续的白色区域， 从而避免了显示画 面中出现白色的横线。
图 3为本发明实的施例二提供的一种显示基板的结构示意图，如图 3 所示， 该显示基板包括： 衬底基板和形成于衬底基板之上的重复排列的多 个像素组， 每个像素组包括四个第一子像素 21、 四个第二子像素 22、 四 个第三子像素 23和四个第四子像素 24， 每个像素组中的子像素以 4 X 4 矩阵排列，每个像素组中的每行子像素包括一个第一子像素 21、一个第二 子像素 22、一个第三子像素 23和一个第四子像素 24。 在一个像素组的四 行子像素中， 其中一行子像素中第一子像素 21、 第二子像素 22、 第三子 像素 23和第四子像素 24依次排列，其中一行子像素中第二子像素 22、第 三子像素 23、第四子像素 24和第一子像素 21依次排列，其中一行子像素 中第四子像素 24、 第一子像素 21、 第二子像素 22和第三子像素 23依次 排列， 其中一行子像素中第四子像素 24、 第一子像素 21、 第二子像素 22 和第三子像素 23依次排列，第一子像素 21、第二子像素 22和第三子像素 23中的至少一个中设置有白色透光区域 2， 第四子像素 24为白色子像素。

具体地， 第一子像素 21为红色子像素， 第二子像素 22为绿色子像 素， 第三子像素 23为蓝色子像素。 一个像素组中， 第一行子像素中红色 子像素、 绿色子像素、 蓝色子像素和白色子像素依次排列， 第二行子像素 中蓝色子像素、 白色子像素、 红色子像素和绿色子像素依次排列， 第三行 子像素中白色子像素、 红色子像素、 绿色子像素和蓝色子像素依次排列， 第四行子像素中绿色子像素、 蓝色子像素、 白色子像素和红色子像素依次 排列。
本实施例中， 红色子像素、 绿色子像素和蓝色子像素的透过率低于 30%, 而白色透光区域 2的透过率接近 100%， 因此在红色子像素、 绿色子 像素和蓝色子像素中的至少一个中设置有白色透光区域 2， 可有效提高显 示基板的透过率。
每行子像素中， 第一子像素 21、 第二子像素 22、 第三子像素 23和 第四子像素 24 中的四个子像素或者其中的任意两个子像素形成一个像素 单元。 本实施例中， 每行子像素中， 第一子像素 21、 第二子像素 22、 第 三子像素 23和第四子像素 24中的两个子像素形成一个像素单元。若第一 子像素 21为红色子像素、 第二子像素 22为绿色子像素、 第三子像素 23 为蓝色子像素， 则第一行子像素中像素单元 3包括依次排列的红色子像素 和绿色子像素， 第一行子像素中像素单元 4包括依次排列的蓝色子像素和 白色子像素， 第二行子像素中像素单元 3包括依次排列的蓝色子像素和白 色子像素， 第二行子像素中像素单元 4包括依次排列的红色子像素和绿色 子像素，第三行子像素中像素单元 3包括依次排列的白色子像素和红色子 像素， 第三行子像素中像素单元 4包括依次排列的绿色子像素和蓝色子像 素，第四行子像素中像素单元 3包括依次排列的绿色子像素和蓝色子像素， 第四行子像素中像素单元 4包括依次排列的白色子像素和红色子像素。
本实施例中， 若每行子像素中， 第一子像素 21、 第二子像素 22、 第 三子像素 23和第四子像素 24中的任意两个子像素形成一个像素单元， 则 未包括第四子像素 24 的像素单元中的至少一个子像素中设置有白色透光 区域 2。 例如， 未包括第四子像素 24的像素单元中的第一子像素 21和 / 或第三子像素 23中设置有白色透光区域 2。 若第一子像素 21为红色子像 素、 第二子像素 22为绿色子像素、 第三子像素 23为蓝色子像素， 例如： 如图 3所示， 第一行子像素的第一像素单元 3包括红色子像素和绿色子像 素， 该第一行子像素的第一像素单元 3未包括白色子像素， 则该第一像素 单元 3中的红色子像素中设置有白色透光区域 2 ; 第一行子像素的第二像 素单元 4包括蓝色子像素和白色子像素， 则该第二像素单元 4中的蓝色子 像素中无需设置白色透光区域 2 ; 第二行子像素的第一像素单元 3包括蓝 色子像素和白色子像素， 则该第一像素单元 3中的蓝色子像素中无需设置 白色透光区域 2 ; 第二行子像素的第二像素单元 4包括红色子像素和绿色 子像素， 该第二行子像素的第二像素单元 4未包括白色子像素， 则该第二 像素单元 4中的红色子像素中设置有白色透光区域 2 ; 第三行子像素的第 一像素单元 3包括白色子像素和红色子像素， 则该第一像素单元 3中的红 色子像素中无需设置白色透光区域 2 ; 第三行子像素的第二像素单元 4包 括绿色子像素和蓝色子像素， 该第三行子像素的第二像素单元 4未包括白 色子像素，则该第二像素单元 4中的蓝色子像素中设置有白色透光区域 2 ; 第四行子像素的第一像素单元 3包括绿色子像素和蓝色子像素， 该第四行 子像素的第一像素单元 3未包括白色子像素， 则该第一像素单元 3中的蓝 色子像素中设置有白色透光区域 2 ; 第四行子像素的第二像素单元 4包括 白色子像素和红色子像素， 则该第二像素单元 4中的红色子像素中无需设 置白色透光区域 2。 上述方案中， 每个像素单元中均包括了白色子像素或 者白色透光区域， 并且每个像素单元中均包括了红、绿、蓝三种颜色元素， 从而提高了显示画面的显示效果。 上述方案中， 设置白色透光区域使得白 色分布更加均匀， 从而在提高显示基板的透过率的同时， 提高了显示画面 的显示效果， 进而优化了用户的视觉体验。 相对于绿色子像素， 人眼对红 色子像素和蓝色子像素的敏感度更低， 因此在红色子像素和蓝色子像素中 设置白色透光区域， 可在提高显示基板的透过率的同时确保显示画面的显 示品质。
本实施例中， 白色透光区域 2 为镂空区域。 本实施例中， 白色透光 区域 2的形状为条状， 可选地， 在实际应用中， 该白色透光区域 2还可以 为其它形状。 本实施例中， 该白色透光区域 2横向设置， 可选地， 在实际 应用中， 该白色透光区域 2还可以采用其它形式设置， 例如， 该白色透光 区域 2可以斜向设置。
本实施例中， 优选地， 在垂直于第一子像素 21、 第二子像素 22和第 三子像素 23 的排列方向的方向上， 例如， 在列方向上， 白色透光区域 2 的尺寸小于或等于第一子像素 21、第二子像素 22或第三子像素 23的尺寸 的 1/3且大于 0。
可选地， 该显示基板还可以包括： 黑矩阵 1， 该黑矩阵 1形成于衬底 基板上， 将各子像素隔开。
作为一种可选方案， 全部第一子像素 21、第二子像素 22和第三子像 素 23中均设置有白色透光区域 2，此种情况不再具体画出。作为一种可选 方案，全部或者部分第二子像素 22中设置有白色透光区域 2， 此种情况不 再具体画出。作为一种可选方案， 全部或者部分第一子像素 21、第二子像 素 22和第三子像素 23中的任意两种中设置有白色透光区域 2， 此种情况 不再具体画出。 在实际应用中， 还可以根据色彩配比的需求设置白色透光 区域的数量以及位置， 以达到提高显示基板的透过率以及确保显示画面的 显示品质的目的， 此处不再一一列举。
实际显示过程中， 通过对原有的红色子像素对应的红色亮度信号、 绿色子像素对应的绿色亮度信号和蓝色子像素对应的蓝色亮度信号进行 处理， 例如根据白色透光区域所占子像素的面积的比例而适当增加或降低 提供给该子像素的电压信号， 使得该子像素的灰阶得到增加或降低， 可使 得设置有白色透光区域的各个红色子像素、绿色子像素和蓝色子像素的色 域更广。
本实施例提供的显示基板的技术方案中， 衬底基板上形成有重复排 列的多个像素组， 每个像素组包括四个第一子像素、 四个第二子像素、 四 个第三子像素和四个第四子像素， 其中， 除了作为白色子像素的第四子像 素之外， 第一子像素、 第二子像素和第三子像素中的至少一个中设置有白 色透光区域， 有效地提高了显示基板的透过率， 从而提高了显示装置的透 过率。 由于本实施例可提高显示装置的透过率， 因此在本实施例的显示装 置的整体亮度与现有技术的显示装置的整体亮度保持一致的前提下， 可降 低背光源的发光亮度。本实施例中，仅部分子像素中设置有白色透光区域， 避免了白色透光区域在行方向上形成连续的白色区域， 从而避免了显示画 面中出现白色的横线。
图 4为本发明的实施例三提供的一种显示基板的结构示意图，如图 4 所示， 本实施例与上述实施例一的区别在于： 本实施例中， 未包括第四子 像素 24的像素单元中的第三子像素 23中设置有白色透光区域 2。
若第一子像素 21为红色子像素、 第二子像素 22为绿色子像素、 第 三子像素 23为蓝色子像素， 例如， 如图 4所示， 第一行子像素的第一像 素单元 3包括红色子像素和绿色子像素， 该第一行子像素的第一像素单元 3未包括白色子像素， 但该第一像素单元 3中未包括蓝色子像素， 则该第 一像素单元 3中无需设置白色透光区域 2 ; 第一行子像素的第二像素单元 4包括蓝色子像素和白色子像素， 则该第二像素单元 4中的蓝色子像素中 无需设置白色透光区域 2 ; 第二行子像素的第一像素单元 3包括绿色子像 素和蓝色子像素， 该第二行子像素的第一像素单元 3未包括白色子像素， 则该第一像素单元 3中的蓝色子像素中设置有白色透光区域 2 ; 第二行子 像素的第二像素单元 4包括白色子像素和红色子像素， 则该第二像素单元 4 中的红色子像素中无需设置白色透光区域 2 ; 第三行子像素的第一像素 单元 3包括白色子像素和红色子像素， 则该第一像素单元 3中的红色子像 素中无需设置白色透光区域 2 ; 第三行子像素的第二像素单元 4包括绿色 子像素和蓝色子像素， 该第三行子像素的第二像素单元 4未包括白色子像 素， 则该第二像素单元 4中的蓝色子像素 23中设置有白色透光区域 2 ; 第 四行子像素的第一像素单元 3包括蓝色子像素和白色子像素， 则该第一像 素单元 3中的蓝色子像素中无需设置白色透光区域 2 ; 第四行子像素的第 二像素单元 4包括红色子像素和绿色子像素， 该第四行子像素的第二像素 单元 4未包括白色子像素， 但该第二像素单元 4中未包括蓝色子像素， 则 该第二像素单元 4中无需设置白色透光区域 2。 上述方案中， 设置白色透 光区域使得白色分布更加均匀， 从而在提高显示基板的透过率的同时， 提 高了显示画面的显示效果， 进而优化了用户的视觉体验。 相对于红色子像 素和绿色子像素， 蓝色子像素的敏感度更低， 因此在蓝色子像素中设置白 色透光区域， 可在提高显示基板的透过率的同时确保显示画面的显示品 质。
图 5为本发明的实施例四提供的一种显示基板的结构示意图，如图 4 所示， 本实施例与上述实施例二的区别在于： 本实施例中， 未包括第四子 像素 24的像素单元中的第三子像素 23中设置有白色透光区域 2。
