當前顯(xian)(xian)(xian)示(shi)(shi)(shi)器(qi)(qi)生產(chan)工(gong)藝的(de)(de)(de)末尾一個階段，要(yao)在顯(xian)(xian)(xian)示(shi)(shi)(shi)器(qi)(qi)的(de)(de)(de)表(biao)面(mian)(mian)(mian)噴涂上(shang)一層(ceng)特殊的(de)(de)(de)涂層(ceng)。該涂層(ceng)可以改善顯(xian)(xian)(xian)示(shi)(shi)(shi)器(qi)(qi)的(de)(de)(de)抗(kang)刮(gua)擦性(xing)能，并且(qie)加強了采(cai)用PC（聚碳酸酯）和(he)PMMA（聚甲(jia)基丙烯酸甲(jia)酯）制造的(de)(de)(de)顯(xian)(xian)(xian)示(shi)(shi)(shi)器(qi)(qi)表(biao)面(mian)(mian)(mian)的(de)(de)(de)質量。要(yao)確保(bao)該涂層(ceng)具有良好的(de)(de)(de)粘(zhan)合性(xing)，必須(xu)對表(biao)面(mian)(mian)(mian)進行(xing)預處理(li)。采(cai)用低溫等離子體技術進行(xing)表(biao)面(mian)(mian)(mian)處理(li)可以對顯(xian)(xian)(xian)示(shi)(shi)(shi)器(qi)(qi)生產(chan)的(de)(de)(de)工(gong)藝流程(cheng)進行(xing)簡化，并大(da)(da)大(da)(da)降(jiang)低廢品率。
