细说高密度小间距LED屏的工艺

设备成色:未知发布时间:2019-11-19 16:45

随着LED显示技术的快速进步,LED显示屏的点间距越来越小,现在市场已经推出P1.4、P1.2的高密度LED显示屏,并且开始应用在指挥控制和视频监控领域。

  在室内监控大屏市场上DLP拼接和LCD液晶拼接这两种显示技术的占据着市场先机,他们虽然各有优势,但是却都共同存在一个问题,那就是显示单元之间的拼缝。高密度LED显示屏具有先天优势可以实现无缝拼接。高密度显示屏像素越来越小,分辨率越来越高,显示画面更加清晰、细腻。在显示标准的高清图像时,可以完全达到分辨率的要求。如果高密度灯管价格越来越低,势必高密度LED显示屏将在室内视频监控领域占有更大市场。
细说高密度小间距LED屏的工艺

  a、LED贴片机意甲竞猜选择:P2以上密度的显示屏一般采用1515、2020、3528的灯,LED管脚外形采用J或者L封装方式。侧向焊接管脚,焊接区会有反光,墨色效果差,势必需要增加面罩以提高对比度。密度进一步提高,L或者J的封装不能满足最小电性能间距需求,必须采用QFN封装方式。国星的1010和晶台的0505均采用此种封装。独创QFN封装焊接独特工艺,这种工艺的特点是无侧向焊接管脚,焊接区无反光,从而使得显色效果非常好。另外采用全黑一体化设计模压成型,画面对比度提高了50%,显示应用画质效果对比以往显示屏更加出色。
