透明,它直接影響到觸摸屏的視覺效果。透明有透明的程度問題,紅外線技術(shù)觸摸屏和表面聲波觸摸屏只隔了一層純玻璃,透明可算,其它觸摸屏這點(diǎn)就要好好推敲一番,“透明”,在觸摸屏行業(yè)里,只是個非常泛泛的概念,很多觸摸屏是多層的復(fù)合薄膜,僅用透明一點(diǎn)來概括它的視覺效果是不夠的,它應(yīng)該至少包括四個特性:透明度、色彩失真度、反光性和清晰度,還能再分,比如反光程度包括鏡面反光程度和衍射反光程度,只不過觸摸屏表面衍射反光還沒到達(dá)CD 盤的程度,對用戶而言,這四個度量已經(jīng)基本夠了。 由于透光性與波長曲線圖的存在,通過觸摸屏看到的圖象不可避免的與原圖象產(chǎn)生了色彩失真,靜態(tài)的圖象感覺還只是色彩的失真,動態(tài)的多媒體圖象感覺就不是很舒服了,色彩失真度也就是圖中的大色彩失真度自然是越小越好。平常所說的透明度也只能是圖中的平均透明度,當(dāng)然是越高越好。
