FAQs (Frequently Asked Questions)

答: 偏光片是一種特殊塑料片,以一定偏光過程傳送光,並從不同偏光方向吸收光。

問: 靜態矩陣 LCD 和動態矩陣 LCD 有何區別?

答: LCD 若非由靜態矩陣网格即由動態矩陣网格製作。動態矩陣的晶體管放在每一像素交接點 上,需少量電流即能控制像素的亮度。因此,動態矩陣顯示器的電流能夠更加頻繁的開關,增 進屏幕刷新時間(例如,你的鼠標似乎在屏幕上滑得更加平穩)。靜態矩陣 LCD 具有一種導 體网格,其像素位於网格的每一交接點。

問: 薄膜晶體管 LCD 的屏面如何顯示?

答: TFT(薄膜晶體管) LCD 屏面上的每一縱橫線都分別附有數據源驅動器和網關驅動器。 TFT 每個晶胞的漏極接上電極。液晶元素的分子排列依是否通上電壓而有所不同。它讓光從 液晶元素的不同排列中滲透出來,從而變換受過偏光處理的光的方向和光量。當兩個偏光過濾 片垂直置於一個偏光光柱,從上方偏光屏面來的光隨著液晶分子的螺旋結構轉向 90 度,穿過 下面的偏光過濾片。通上電壓,液晶分子從原來的螺旋結構變成垂直排列,而光的方向也不再 轉向 90 度。在此情況下,從上面偏光屏面來的光則不會穿過下面的偏光過濾片。

問: 與 CDT 相比,TFT LCD 的優勢何在?

答: CDT 顯示器中,一個電子槍以撞擊熒光玻璃上的偏光電子方式發射電子和一般光。因此, CDT 顯示器基本上以模擬紅綠藍信號操作。TFT LCD 顯示器則是運用液晶屏面顯示輸入圖 像的裝置。TFT 與 CDT 有根本不同的結構﹕其每一晶胞皆有動態矩陣結構和獨立的活性元 素。TFT LCD 有兩個玻璃屏面,其空間裝滿液晶。當每一晶胞接上電極並通上電壓時,液晶 分子結構則受到改變,從而控制從里面射向顯示圖像的光。TFT LCD 比 CDT 有多重優勢, 因為它能變得特別薄,又沒有閃光,原因是它不使用掃描法。

問: LCD 顯示器的垂直頻率為何最大祗有 60 赫茲?

答: 與 CDT 顯示器不同,TFT LCD 屏幕具有固定的分辨率。例如,XGA 顯示器祗有 1024x3 (紅綠藍)x768 個像素,而更高分辨率若無更多的軟體處理則不可得。本屏幕則定為 65 赫茲 點脈沖最大顯示,即 XGA 顯示器的標準頻率之一。既然此點脈沖是 60Hz/48kHz,此顯示器 的最大頻率則為 60 赫茲。

問: 現有何種廣角技術?其功能如何?

答: TFT LCD 屏幕是透過液晶雙重折射放進內部光亮的元素控制器/顯示器。它利用內部光折 射至液體元素主軸的這一特性,控制內部光的方向、將光顯示出來。由於液晶上內部光的折射 比率隨光的內部角度變化,TFT 的視角比 CDT 的視角更窄。通常,視角指對比度為 10 的角 度點。目前有許多擴大視角的開發途徑。最常用的方法為利用廣視角片,透過變換折射比率來 擴大視角。IPS(面內開關)或 MVA(多項垂直校準)也被用來擴大視角。飛利浦 181AS 型 使用的則是先進的IPS技術。

問: LCD 顯示器如何沒有閃光?

答: 從技術上說,LCD 也閃動,不過這個現象的原因與 CRT 顯示器的不同—其並不妨礙視覺 舒適感。LCD 的閃光指正負極電壓差造成的一般不易覺察的發光。另一方面,傷害眼睛的
