手機(ji)曲(qu)面(mian)鉛(qian)(qian)(qian)玻(bo)(bo)璃(li)蓋(gai)板近一(yi)年(nian)內興起并迅速走向(xiang)消費(fei)者，去年(nian)，夏普一(yi)款5曲(qu)面(mian)3D鉛(qian)(qian)(qian)玻(bo)(bo)璃(li)手機(ji)問世，一(yi)時(shi)間(jian)在行(xing)業內引(yin)起了(le)一(yi)波小(xiao)高潮。鉛(qian)(qian)(qian)玻(bo)(bo)璃(li)有著硬度高等自(zi)身的優(you)(you)勢但(dan)同時(shi)也有缺陷，如何(he)將鉛(qian)(qian)(qian)玻(bo)(bo)璃(li)的優(you)(you)勢發(fa)(fa)揮到很(hen)好，劣(lie)勢降低？今天我們(men)以這款5曲(qu)3D鉛(qian)(qian)(qian)玻(bo)(bo)璃(li)蓋(gai)板為例，了(le)解(jie)一(yi)下。現在市場主要(yao)的后(hou)蓋(gai)使用材質及(ji)相(xiang)關特性如下：可以看到，鉛(qian)(qian)(qian)玻(bo)(bo)璃(li)的硬度及(ji)耐磨(mo)性很(hen)好，剛性、電磁(ci)屏(ping)蔽性等性能均占優(you)(you)勢，但(dan)脆性是(shi)一(yi)大缺陷，如何(he)將鉛(qian)(qian)(qian)玻(bo)(bo)璃(li)的優(you)(you)勢發(fa)(fa)揮到很(hen)好同時(shi)將劣(lie)勢降低，鉛(qian)(qian)(qian)玻(bo)(bo)璃(li)生產廠家需(xu)要(yao)從產品設計上(shang)來考量(liang)：
