今年广交会期间深圳口岸入出境外国人78.3万人次 创历届新高

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。
