Description

LED显示模块和LED显示装置
本申请要求在2020年07月22日提交中国专利局、申请号为202010713331.5的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及显示技术领域，例如涉及一种发光二极管(Light Emitting Diode，LED)显示模块和LED显示装置。
背景技术
随着社会的不断发展，LED行业成为最为活跃的行业之一，LED显示屏产品逐渐走进社会、生活的多个领域。与此同时，随着LED显示屏技术的创新与发展，单位面积分辨率高的小间距LED显示模块已经成为LED显示屏的主流产品，它可以显示更高清晰度的图形图像和视频，也可以显示更多的视频和图像画面，尤其是在图像拼接方面的运用，可以做到任意大面积拼接。
通常，LED显示装置是由多个LED显示模块拼接而成的。每个LED显示模块包含多个呈阵列排布的像素，每一像素由三个发光LED芯片(每一个发光LED芯片被称为子像素)构成。然而相关技术中，多个LED显示模块在拼接时必然存在拼接缝，在拼接缝处容易出现透光。邻近拼接缝处的两行或两列的LED子像素中，一行所有子像素均为同一种颜色，而另一行也均为同一种颜色(或者，一列所有子像素均为同一种颜色，另一列所有子像素也为同一种颜色)，直接导致拼接缝处显示黄色/青蓝色/粉红色等色线问题，从而影响LED显示装置的显示效果。

实施例五
图7是本发明实施例五提供的一种LED显示装置的结构示意图，参考图7，该LED显示装置包括多个阵列排布的本发明任意实施例所述的LED显示模块。
参考图7，LED显示装置是由多个LED显示模块拼接形成的大的显示模组，在拼接时会形成图7所示的拼接缝1和拼接缝2。在由多个LED显示模块拼接形成LED显示装置时，通过设置LED显示模块的第一个像素行中的至少一个第一子像素行中的第一行，第一子像素行包括第一子像素、第二子像素和第三子像素中的至少两种，最后一个像素行中的至少一个第二子像素行中的最后一行，第二子像素行包括第一子像素、第二子像素和第三子像素中的至少两种，使得LED显示模块的第一个像素行边沿的像素发光来源至少来自两种颜色的子像素，例如第一子像素、第二子像素和第三子像素中的至少两种组合，同样地，LED显示模块的最后一个像素行边沿的像素发光来源也至少来自两种颜色的子像素，从而使得当多个LED显示模块拼接时，在拼接处，能够保证每个边沿的LED像素发出的光均来自三种颜色的子像素中的至少两种，从而可以改善拼接缝处出现黄光、青蓝光、粉红光等色线问题。
