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。
正如背景技术所述，随着市场的需求，高成像质量、大视场、小体积等因素也越来越得到重视。尤其是在目前正快速发展的AR(Augmented reality)和VR(Virtual reality)领域。目前已出现的微发光二极管(Micro-LED)显示技术，是LED微缩化和矩阵化技术，指的是在一芯片上集成的高密度微小尺寸的LED阵列。通过集成电路工艺制成驱动电路，来实现每一个发光点定址控制和单独驱动的显示技术。由于Micro LED单体的结构限制，在LED矩 阵化的过程中，每个LED单体之间的间隙较大，使得显示设备的显示效果较差。
基于此，本发明实施例提供了一种显示设备，有效解决现有技术存在的技术问题，能够将初始发光点图像转换为像素点更多的预设发光点图像出射，提高了显示设备的显示效果。
为实现上述目的，本发明实施例提供的技术方案如下，具体结合图1至图10对本发明实施例提供的技术方案进行详细的描述。
