 <div class="aboutk_tit">索尼三星的技术全都有？中麒布局单芯片封装为何如此引人关注</div>

 <div class="text_neirong"><p>作为半导体的一大分支，摩尔定律对于LED显示产业同样适用。对于LED显示产业，点间距微缩是显示屏产业的发展趋势。当前LED显示正走向微间距时代，多种技术路线并行，因此接下来的技术路线走向极为关键。</p><p style="text-align: center; margin-top: 20px; margin-bottom: 20px;"><img src="/upload_files/2022-03/1647323980135786.png" title="1647323980135786.png" alt="d29bf2990fbf2df3868375fa3bea4f2f.png"/></p><p style="margin-top: 20px; margin-bottom: 20px;">据行家说产业研究中心数据显示，2021年全球LED显示屏市场从2020年疫情影响中恢复，P1.0以下的微间距显示屏和P2.5以下小间距显示屏的市场规模有明显增长，其中微间距显示增速最快。</p><p style="margin-top: 20px; margin-bottom: 20px; text-align: center;"><img src="/upload_files/2022-03/1647324012443399.png" title="1647324012443399.png" alt="d29bf2990fbf2df3868375fa3bea4f2f.png"/></p><p style="margin-top: 20px; margin-bottom: 20px;">随着间距的微缩化发展，P1.0以下SMD单灯形式会面临可靠性问题，需要采用集成封装形式，而集成封装COB对工艺和材料的精度要求较高。在COB的印刷环节，Mini LED芯片的焊脚相比SMD灯珠焊脚要小，且微间距的密度更高，因此要求印刷钢网的开孔数量增加、孔径缩小、精度提高。在固晶环节，Mini LED芯片尺寸越小，固晶动作偏移和PCB焊盘位置偏移对固晶良率的影响越大，因此要提高固晶设备和PCB基板的精度。此外，COB集成封装方式无法分光分色和混编，需在后段工艺进行校正以提升显示的一致性。</p><p style="margin-top: 20px; margin-bottom: 20px; text-align: center;"><img src="/upload_files/2022-03/1647324035364393.png" title="1647324035364393.png" alt="029c55465fc37e92e955b704d4d2f66d.png"/></p><p>上述是目前COB路线在生产过程中遇到的主要问题。为了推进LED显示产业的发展，克服当下的瓶颈问题，中麒光电创新性地推出了单芯片封装技术MIP。单芯片封装就是用Mini LED芯片，通过巨量转移技术，做成芯片级的封装体， 然后将封装体集成为Mini COB显示模组。具体来说具有如下几大方面的优势：</p><p><br/></p><ul class=" list-paddingleft-2" style="list-style-type: disc;"><li><p>可实现从圆片到封装体，单芯片封装技术可大幅度优化芯片到显示面板之间的工艺条件。</p></li><li><p>从小芯片到大间距封装体， 降低了倒装COB封装对基板的精度要求，更提高了封装的良率及产品可靠性。</p></li><li><p>单芯片封装RGB可任意排列组合成模组，适应任何点间距的选用(P1.8~P0.6)，通用性强。</p></li><li><p style="margin-bottom: 20px;">单芯片封装可实现混晶、分光分色，呈现极佳显示效果。</p></li></ul><p style="margin-bottom: 20px; text-align: center;"><img src="/upload_files/2022-03/1647324094271444.png" title="1647324094271444.png" alt="8da7b5d3fb4eab3445418f5cc18e5d9c.png"/><br/></p><p style="margin-bottom: 20px;">行家说Research认为，单芯片封装技术MIP是化整为零的思想，将一整块面板分开封装，通过对小块面积良率的控制，解决了大面积控制良率难度较高的问题。基于单芯片封装技术MIP的Mini COB Lite产品可以充分发挥其技术、产品迭代快的特性，将技术更新快速应用于产品市场，及时满足微间距LED显示快速增长的市场需求。</p><p style="margin-bottom: 20px;">将目光放眼全球，可以看到，索尼黑彩晶和三星The Wall，分别代表了当前LED显示屏的主流技术路线MIP和COB。COB是对工艺环节和材料做减法，具有较高的降本潜力。单芯片封装则可以解决当前COB遇到的精度良率和校正等问题。可以说，COB和MIP，都有其各自的优劣势。与此同时，各技术路线受制市场环境复杂影响，具备各种不确定性，何种技术路线最终可以笑到最后也未可知，如果企业有实力多线并行，将大大提高成功的概率。</p><p style="margin-top: 20px;
