利亚德获专利,LED显示单元电源接头可在对插时控制通断

11月6日,利亚德(300296)的发明专利《LED显示装置的对插装置及LED显示装置》获授权,申请号为CN202210603436.4。

拼装LED显示单元时,电源线可能已经接通,后续对插动作因而需要避免带电接触。设计让母座导电件受开关控制,并在公插端设置可以移动的触头。触头伸出时与母座连接,缩回壳体后则与母座分离。是否导通取决于接头状态,不再仅由外部电源是否接入决定。专利针对的是显示单元继续装配时的用电安全。

截至此次授权消息披露时,利亚德今年获得的各类专利授权共40项,比上年同期减少14.89%。在2026年上半年,公司研发投入为1.85亿元,同比增长2.07%。企业知识产权记录中,利亚德光电股份有限公司名下可查到904条专利信息和173条著作权信息。
