显示器 分為 : 陰極射線管 显示器 液晶 显示器 電漿 显示器 電子紙 显示器 OLED 显示器 ( 有機發光二極體 )
陰極射線管显示器 因為最廣為人知的用途是用於構造顯示系統,所以俗稱  映像管 ,它是利用 陰極 電子槍 發射 電子 ,在 陽極 高壓的作用下,射向 螢光屏 ,使螢光粉發光
陰極射線管是由 克魯克斯 首創,所以又被稱為克魯克斯管。由於它笨重、耗電,所以在部分領域正在被輕巧、省電的 液晶显示器 取代。
液晶显示器 是一種 高分子 材料,因為其特殊的 物理 、 化學 、 光學 特性, 20 世紀中葉開始被廣泛應用在輕薄型的 顯示技術 上。 液晶相要具有特殊形狀分子組合始會產生,它們可以流動,又擁有結晶的光學性質。
液晶的定義,現在以放寬而囊括了在某一溫度範圍可以是現液晶相,在較低溫度為正常結晶之物質。而液晶的組成物質是一種有機化合物,也就是以碳為中心所構成的化合物。 同時具有兩種物質的液晶,是以分子間力量組合的,它們的特殊 光學性質 ,又對 電磁場 敏感,極有實用價值。
電漿显示器 是一種由 自由電子 和帶電 離子 為主要成分的物質形態,廣泛存在於 宇宙 中,常被視為是物質的第四態,被稱為電漿態,或者「超氣態」。
電漿具有很高的 電導率 ,與 電磁場 存在極強的 耦合 作用。電漿是由 克魯克斯 在 1879 年發現的, 1928 年美國科學家 歐文 · 蘭米爾 和湯克斯( Tonks )首次將「電漿( plasma )」一詞引入物理學,用來描述氣體放電管里的物質形態 [1] 。
電子紙 是一種新型的 显示器 ,最大特色在於能自由彎曲,與 紙 的十分相似,其 色彩 對比高、 解析度 高、 耗電量 小、製造成本低。
電子紙的發展是為了仿效墨水在真實紙張上的顯現 .  不同於一般的平板显示器 ,  需要使用到背光燈照亮象素 ,  電子紙如同普通紙一樣可以反射環境光 .  而且電子紙可以不再加電的情況下保留住原先顯示的圖片和文字狀態 .
OLED 显示器 有機發光二極體 簡稱 OLED 與  TFT - LCD 「薄膜電晶體液晶显示器」是不同類型的產品。部分國外又稱  OLED  為 有機電激發光顯示
OLED 具有自發光性、廣視角、 高對比、低耗電、高反應速率、全彩化、製程簡單等優點, OLED 显示器的種類可分單色、多彩及全彩等種類,而其中以全彩製作技術最為困難, OLED 显示器依驅動方式的不同又可分為被動式與主動式。
結構 OLED 的基本結構是由一薄而透明具半導體特性之銦錫氧化物( ITO ),與電力之正極相連,再加上另一個金屬陰極,包成如三明治的結構。整個結構層中包括了:電洞傳輸層( HTL )、發光層( EL )與電子傳輸層( ETL )。
比較 簡單分為 OLED ( organic light-emitting diodes )和  PLED ( polymer light-emitting diodes ),目前均已開發出成熟產品。 PLED 主要優勢相對於 OLED 是其柔性大面積顯示。但由於產品壽命問題,目前市面上的產品仍以 OLED 為主要應用。
