CRT（陰極射線管）已經(jīng)主要地應(yīng)用于各種顯示設(shè)備中，這些顯示設(shè)備用于辦公自動(dòng)化（OA）設(shè)備，如文字處理器、筆記本型個(gè)人電腦和個(gè)人計(jì)算機(jī)監(jiān)測(cè)器、移動(dòng)電話終端和電視機(jī)。液晶顯示器具有的優(yōu)點(diǎn) 在于薄、重量輕和低的能量消耗，并且在近幾年中，它已經(jīng)***地取代CRT。液晶顯示器通常包括液晶單元（liquid crystal cell）和偏振片。偏振片通常具有保護(hù)薄膜和偏振薄膜，典型地通過(guò)干燥由聚乙烯醇薄膜與碘組成的偏振薄膜、拉伸、在該偏振薄膜的兩個(gè)表面上堆疊保護(hù) 薄膜而獲得。透射型液晶顯示器通常包含在液晶單元兩側(cè)上的偏振片，偶爾包含一個(gè)或多個(gè)光學(xué)補(bǔ)償薄膜。反射型液晶顯示器通常依次包含反射板、液晶單元、一個(gè)或多個(gè)光學(xué)補(bǔ)償薄膜和偏振片。液晶單元包含液晶分子，包封所述液晶分子的兩個(gè)基質(zhì)，和施加電壓至所述液晶分子的電極層。取決于液晶分子的取向狀態(tài)的改變，所述液晶單元轉(zhuǎn)換開(kāi)和關(guān)的顯示，并且對(duì)透射型和反射型均適用，其中，提出的顯示模式包括TN（扭轉(zhuǎn)向列），江蘇

碘系偏光片：容易獲得高透過(guò)率、高偏振度的光學(xué)特性，但耐高溫高濕的能力較差。價(jià)格比較便宜，所以市場(chǎng)占有率高達(dá)80%~90%，應(yīng)用領(lǐng)域***，如：手表，計(jì)算機(jī)，PC，OA機(jī)器等，所需LCD都大量采用碘系偏光片。染料系偏光片：不容易獲得高透過(guò)率、高偏振度的光學(xué)特性，但耐高溫高濕的能力較好。所以在汽車(chē)，船舶，航空器，戶外量測(cè)儀器上就得采用此類(lèi)耐久性偏光片。

染色，延伸，貼合，干燥為**主要的步驟，其中染色材料配方是重要的技術(shù)關(guān)鍵。另外PVA的延伸定向控制也會(huì)影響偏光膜的光學(xué)特性。高分子膜在經(jīng)過(guò)延伸之后，通常機(jī)械性質(zhì)會(huì)降低，變得易碎裂;且PVA膜具有親水性，在濕熱的環(huán)境下很快會(huì)變形、收縮、衰退，所以在偏光基體PVA延伸完后，要在兩側(cè)貼上三醋酸纖維(TAC)所組成的透明基板，一方面可做保護(hù)，一方面則可防止膜的回縮。
