FAQs (Frequently Asked Questions)

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: 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 CRT 閃光是由於熒光物體的閃/滅動作變得顯而易見
