本實用新型(xing)涉(she)(she)及(ji)一種導電膜，涉(she)(she)及(ji)用于觸摸屏的導電膜。

背景技術：

觸摸屏已經廣泛應用于個人數(shu)字助理(li)(Personal Digital Assistant，PDA)或智能手(shou)機(ji)等手(shou)持電子設(she)備。

現有的(de)(de)觸摸屏由于(yu)使用氧化(hua)(hua)銦錫(ITO)，隨著現今(jin)的(de)(de)電(dian)(dian)子設(she)備(bei)的(de)(de)屏幕尺(chi)寸(cun)向大型化(hua)(hua)的(de)(de)發展，現有的(de)(de)觸摸屏隨著尺(chi)寸(cun)的(de)(de)變(bian)化(hua)(hua)，在電(dian)(dian)極之間的(de)(de)信號(hao)波(bo)形會鈍化(hua)(hua)，從而導致響應速度會變(bian)慢。

雖然現有(you)的(de)導電(dian)(dian)膜已(yi)經開發(fa)出了(le)在導電(dian)(dian)膜中使用金(jin)屬絲(si)形(xing)成導電(dian)(dian)層的(de)技術，然而由于(yu)金(jin)屬絲(si)的(de)分布的(de)輪廓或形(xing)狀的(de)不同，使得導電(dian)(dian)膜在視覺上產生云紋現象，影響(xiang)使用者的(de)感受。

因此(ci)，有必要對導電膜的云紋現象進行研究，以(yi)抑制云紋現象的產生。

技術實現要素：

具體實施方式

為了(le)更加清楚地(di)理解本實用新(xin)型的(de)技(ji)術(shu)方(fang)案和有(you)益效(xiao)果，以下結(jie)合附圖(tu)對(dui)本實用新(xin)型做出詳細(xi)說明，但是對(dui)具體實施例(li)的(de)描述均不(bu)是對(dui)本實用新(xin)型技(ji)術(shu)方(fang)案的(de)限制(zhi)，任何依(yi)據本實用新(xin)型構思做出的(de)非實質(zhi)性(xing)改進都落入本實用新(xin)型要求保(bao)護的(de)技(ji)術(shu)方(fang)案范疇。

如圖1所示，本實用新型提供一(yi)種導電(dian)(dian)膜100，包括(kuo)基本上透(tou)明的本體(ti)102以及(ji)形(xing)成于本體(ti)102上的引(yin)線電(dian)(dian)極。

其中，并且包(bao)括有金(jin)屬絲形(xing)成的(de)多個導電透明層(ceng)。透明層(ceng)的(de)端部可以經過其他(ta)連接方(fang)式從而(er)與引線電極(圖中未示出)電性連接。

多個導電透明層中的第一導電透明層108中的金屬(shu)絲162排列為規則網格形(xing)(xing)狀(zhuang)(如(ru)圖2所(suo)示)，并且(qie)其中的金屬(shu)絲162相互交叉。例(li)如(ru)，網格形(xing)(xing)狀(zhuang)可以是(shi)正(zheng)方(fang)形(xing)(xing)。然而可選的，也可以是(shi)其他形(xing)(xing)狀(zhuang)。

如(ru)圖1、2所示，第(di)二導(dao)(dao)電(dian)(dian)(dian)透明層(ceng)(ceng)110覆蓋在第(di)一(yi)導(dao)(dao)電(dian)(dian)(dian)透明層(ceng)(ceng)108上，多個(ge)(ge)(ge)導(dao)(dao)電(dian)(dian)(dian)透明層(ceng)(ceng)中(zhong)的(de)(de)第(di)二導(dao)(dao)電(dian)(dian)(dian)透明層(ceng)(ceng)110中(zhong)的(de)(de)金屬(shu)絲164以(yi)多個(ge)(ge)(ge)第(di)一(yi)導(dao)(dao)電(dian)(dian)(dian)透明層(ceng)(ceng)108中(zhong)金屬(shu)絲162劃分(fen)的(de)(de)網格形狀(zhuang)為邊(bian)界(jie)形成(cheng)多個(ge)(ge)(ge)對應(ying)的(de)(de)第(di)一(yi)單(dan)元模塊。并且(qie)優選的(de)(de)，每(mei)個(ge)(ge)(ge)第(di)一(yi)單(dan)元模塊中(zhong)金屬(shu)絲162形成(cheng)不規則(ze)的(de)(de)輪廓(kuo)線，并且(qie)分(fen)布(bu)在每(mei)個(ge)(ge)(ge)第(di)一(yi)單(dan)元模塊中(zhong)的(de)(de)金屬(shu)絲164沒有彼(bi)此交叉。由此，具(ju)有不規則(ze)的(de)(de)輪廓(kuo)線第(di)二導(dao)(dao)電(dian)(dian)(dian)透明層(ceng)(ceng)110抑制由于具(ju)有規則(ze)的(de)(de)網格形狀(zhuang)的(de)(de)第(di)一(yi)導(dao)(dao)電(dian)(dian)(dian)透明層(ceng)(ceng)108產生的(de)(de)云紋現(xian)象。

多(duo)個導(dao)電(dian)透(tou)(tou)明層(ceng)(ceng)還包括表(biao)面透(tou)(tou)明層(ceng)(ceng)118，其用于形(xing)成覆蓋其下(xia)的其他導(dao)電(dian)透(tou)(tou)明層(ceng)(ceng)的偽(wei)裝層(ceng)(ceng)，從而使得經過導(dao)電(dian)透(tou)(tou)明層(ceng)(ceng)光線(xian)的透(tou)(tou)射均勻。

可(ke)選的(de)，在第二(er)導(dao)(dao)電透(tou)(tou)明(ming)層(ceng)110上還可(ke)以增加設(she)置第四導(dao)(dao)電透(tou)(tou)明(ming)層(ceng)140(圖中(zhong)未(wei)示出)，其中(zhong)第四導(dao)(dao)電透(tou)(tou)明(ming)層(ceng)140種的(de)金屬(shu)絲(si)166以多(duo)個第一(yi)導(dao)(dao)電透(tou)(tou)明(ming)層(ceng)108中(zhong)金屬(shu)絲(si)162劃分(fen)的(de)網格形狀(zhuang)為邊界形成多(duo)個對(dui)應(ying)的(de)第二(er)單(dan)元模塊(kuai)。第二(er)單(dan)元模塊(kuai)1中(zhong)的(de)金屬(shu)絲(si)164可(ke)以任(ren)意(yi)設(she)置。通過隨機設(she)置金屬(shu)絲(si)166可(ke)以更(geng)加有效的(de)抑制云紋現(xian)象。
