3.4飛利浦平面顯示器像素殘缺規定

飛利浦致力於提供最優質的產品。本公司運 用同行業最先進的製造程序,實行嚴格的品 質管理。不過,用於平面屏幕顯示器的TFT LCD屏幕若有像素或分像素殘缺有時也是事 在難免。沒有任何廠家能夠擔保所有的屏幕 皆無像素殘缺,飛利浦卻保證任何顯示器, 如果超過不可接受的殘缺量,必將得到擔保 條件下的維修或替換。此處須知描述不同種 類的像素殘缺,規定每一種類可以接受的殘 缺水準。為了符合擔保下的維修或替換,TFT LCD屏幕上的像素殘缺量須得超過這些可接 受水準。例如,18.5英寸的XGA顯示器上,不 足0.0004%的分像素可能屬於殘缺。此外,鑒 於有些像素殘缺種類或組合比其他更引人注 意,飛利浦對此種類確定更高的品質標準。 本規定全球適用。

像素和分像素

一個像素,或稱圖像元素,由三個屬於紅綠 藍主顏色的分像素組成。許多像素在一起形 成一個圖像。像素裡的所有分像素全被照亮 時,三個帶顏色的分像素一起以一個白色像 素出現。當他們全部變暗時,三個帶顏色的 分像素一起以一個黑色像素出現。其他類的 明暗分像素組合則以其他顏色的單個像素出 現。

像素殘缺種類

像 素 和 分 像 素 殘 缺 在 屏 幕 上 以 不 同 形 式 出 現。有兩類像素殘缺,每一類內有多種分像 素殘缺。

亮點瑕疵

亮點瑕疵就是始終亮著或「開啟」的圖素或 子圖素;也就是說,亮點是當顯示器顯示暗 色圖形時,會突顯出來的子畫素。以下是亮 點瑕疵的幾種類型:

一個發亮的紅綠藍分像素
