FAQs (Frequently Asked Questions)

問: 何為偏光過程 ?

答: 偏光過程基本上即是使光朝一個方向照明。光為電磁波。電磁場沿著與光柱傳播相垂直的 方向震動。這些磁場的方向即稱為“偏光方向”。正常的或非偏光的光有不同方向的磁場;偏 光的光祗有一個方向的磁場。

問: 何為偏光片 ?

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?
