Description

像素结构、显示面板以及显示装置

在一些显示产品中，除了采用4合一封装的LED外，还采用单色RGB的LED进行子像素排布，其子像素排布比较简单，如图1所示。例如，该Mini LED显示产品的显示架构下，行、列管通道连接LED的正、负极，行管通过mux复用减少IC使用数量，通过时序控制行管开启和关闭及列管输出实现子像素的点亮，通常这种架构下，使用一块甚至多块PCB板放置驱动IC，显示面板几乎要拉出所有LED的正负极到PCB上，使得对玻璃侧边引线工艺要求较高，增加工艺成本，且增加模组厚度。因此，出现了一种将LED与像素芯片结合的混合驱动的架构。如图2所示，一个像素单元中除了可以包括多个子像素单元外，还可以包括驱动单元，该驱动单元分别与每个子像素单元电连接，在扫描信号Gate的作用下，将对应的显示信号Data写入到对应的子像素单元。混合驱动方式的像素驱动的TFT(Thin Film Transistor， 薄膜晶体管)可以直接设计在玻璃基板上，而驱动单元会占用像素一定的空间，因此可以与子像素进行重排。
本公开给出如下几种混合驱动模式下的像素结构、显示面板和显示装置。
请参考图3、图5、图7、图9、图11、图13和图15所示，本公开实施例提供一种像素结构，该像素结构包括不同颜色的三个子像素单元和驱动单元10，三个子像素单元包括第一子像素单元21、第二子像素单元22和第三子像素单元23，驱动单元，被配置为分别向每个子像素单元发送对应的显示数据；三个子像素单元排列在驱动单元10的一侧或两侧。如此，将子像素与驱动单元结合的混合像素结构应用到显示产品中，其子像素排布和像素阵列可以根据驱动方式的不同进行灵活调整，走线较简单，工艺要求较低，降低工艺成本，降低模组厚度。
其中，三个子像素单元的颜色可以为红色、绿色和蓝色。或者，可以采用其他颜色搭配。
在一种示例性实施例中，当三个子像素单元排列在驱动单元10的一侧时，可采用如图3、图5、图7和图9的像素结构。
在一种示例性实施例中，如图3所示，该像素结构可以采用一行的排列方式，三个子像素单元和驱动单元10并排设置在同一行。这里，在图3中，以第一子像素单元21、第二子像素单元22和第三子像素单元23并排设置在驱动单元10的右侧为例进行示意。例如，以三个子像素单元采用红色、绿色和蓝色颜色搭配为例，第一子像素单元21可以为红色，第二子像素单元22可以为绿色，第三子像素单元23可以为蓝色。颜色与子像素单元的对应关系可根据需要匹配，这里不做限定。在另一示例性实施例中，第一子像素单元21、第二子像素单元22和第三子像素单元23可以并排设置在驱动单元10的左侧，即驱动单元10设置在最右侧。
在一种示例性实施例中，如图5所示，该像素结构还可以采用一列的排列方式，三个子像素单元和驱动单元10并排设置在同一列。这里，在图3中，以第一子像素单元21、第二子像素单元22和第三子像素单元23并排设置在驱动单元10的上侧为例进行示意。在其它示例性实施例中，第一子像素单元21、第二子像素单元22和第三子像素单元23可以并排设置在驱动单元 10的下侧，即驱动单元10设置在最上侧。
在一种示例性实施例中，图4为本公开实施例提供的利用图3所示的像素结构阵列排布的显示面板的结构示意图。如图3和图4所示，该显示面板可以包括：阵列排布的多个像素结构，每个像素结构中的三个子像素单元和驱动单元沿着阵列的行方向展开，其中，在每个像素结构中，驱动单元10位于该像素结构的最左侧，第一子像素单元21、第二子像素单元22和第三子像素单元23并排设置在驱动单元10的右侧。在其它示例性实施例中，显示面板可以采用驱动单元10位于像素结构最右侧的结构。
在一种示例性实施例中，图6为本公开实施例提供的利用图5所示的像素结构阵列排布的显示面板的结构示意图。如图5和图6所示，该显示面板可以包括：阵列排布的多个像素结构，每个像素结构中的三个子像素单元和驱动单元沿着阵列的列方向展开，其中，在每个像素结构中，驱动单元10位于该像素结构的最下端，第一子像素单元21、第二子像素单元22和第三子像素单元23并排设置在驱动单元10的上侧。在其它示例性实施例中，显示面板可以采用驱动单元10位于像素结构最上侧的结构。
这里，图4和图6仅给出采用图3和图5所示的像素结构的显示面板的示例性实施方式，本公开实施例所提供的显示面板包括但不限于上述方式，例如，图4和图6所示出的显示面板中的第一子像素单元21、第二子像素单元22和第三子像素单元23的位置可以互换，这里不做限定。

在一种示例性实施例中，如图9所示，该像素结构可以采用两列的排列方式，第一列为并排设置的三个子像素单元，即并排设置的第一子像素单元21、第二子像素单元22和第三子像素单元23，另一列为驱动单元10。例如，实际应用中，该像素结构可以采用第一列为驱动单元，第二列为并排的子像素单元的排列方式。例如，图9所示的像素结构中的三个子像素单元的位置可以互换，这里不做限定。
在一种示例性实施例中，图8为本公开实施例提供的利用图7所示的像素结构阵列排布的显示面板的结构示意图。如图7和图8所示，该显示面板可以包括：阵列排布的多个像素结构，每个像素结构中的三个子像素单元沿着阵列的行方向展开，驱动单元10位于三个子像素单元的下方。在其它示例性实施例中，显示面板可以采用驱动单元10位于三个子像素单元上方的结构。

在一些实施例中，像素结构可以采用三行的排列方式。例如，如图11所示。其中，第一子像素单元21和第三子像素单元23并排位于第一行，驱动单元位于第二行，第二子像素单元22位于第三行。或者，排在第一行的可以是第二子像素单元22和第三子像素单元23，排在第三行的可以是第一子像素单元21，这里不限定排在第一行和第三行的子像素单元是哪个，三个子像素单元中的任意两个排在第一行，另外一个排在第三行，形成三角形状即可。
在一种示例性实施例中，如图13所示，该像素结构可以采用三列的排列方式，其中，第一子像素单元21和第三子像素单元23并排位于第一列，驱动单元位于第二列，第二子像素单元22位于第三列。或者，排在第一列的可以是第二子像素单元22和第三子像素单元23，排在第三列的可以是第一子像素单元21。这里不做限定每个子像素单元所在的列，三个子像素单元中的任意两个排在第一列，另外一个排在第三列即可。
