什麼是IPS顯示器?

IPS顯示器以其醒目的顏色和寬廣的視角而廣受歡迎。實際上,與早期的TN(扭曲向列)結構相比,聯想現在提供了更多的基於In Plane Switching或IPS顯示技術的筆記本電腦平板電腦顯示器,儘管TN機型仍受到一些用戶的青睞,例如競爭激烈的PC遊戲玩家。

那麼,IPS顯示器真正提供了什麼?哪些筆記本電腦和顯示器買家最有可能從IPS技術中受益?為什麼有些用戶仍然喜歡老式TN顯示器?繼續閱讀,以獲取這些和其他問題的答案。

IPS與TN顯示:有什麼區別?

IPS和TN是不同類型的TFT LCD(薄膜晶體管液晶顯示器)。在最簡單的層次上,LCD依靠通電液晶的光調製特性以及協調的濾光偏振片(在晶體的後面和前面)來控制屏幕上顯示的內容。通過對每個晶體(或不施加)施加電壓,使光通過(或不通過)偏振器。以微秒為間隔管理這些更改後,您將獲得平滑的運動圖像。

聯想提供具有IPS 顯示屏的筆記本電腦的數十個功能:

  • THINKPAD:全球排名第一的商務筆記本電腦
  • IDEAPAD:辦公和家庭時尚筆記本電腦
  • 瑜伽:靈活的2合1筆記本電腦/平板電腦組合

TN和IPS顯示器在影響光的偏振層對齊方式上有所不同。如果這聽起來太技術性,那就要知道,當偏振片進行類似的排列時,光可以通過,但是當它們放置在不同的方向時,光會被阻擋。當您將液晶分子放置在偏振器層之間並施加電壓時,會發生有趣的事情:

  • TN偏振器彼此垂直對齊。沒有電壓,液晶分子自然會“扭曲”光,因此它可以從垂直排列的偏振器發出,在晶體中扭曲,然後穿過相關的水平偏振器。但是,如果您施加電壓(換句話說,如果破壞晶體的自然屬性),則光線將不再扭曲,並且垂直偏振器方向會阻止光線通過。
  • IPS偏振器平行排列,通常可以使所有光線通過。但是同樣,靜止的液晶分子扭曲光以破壞正常流動。因此,IPS顯示器的工作方式與TN顯示器相反。電壓使光通過,而不是施加電壓來阻止光通過。它可以防止液晶扭曲光,使其像往常一樣可以通過平行偏振器。

當然,還有更多的東西。但是,這使您大致了解TN和IPS顯示的區別。正是這些差異為每種類型的顯示器賦予了特定客戶獨特的優勢。例如,與TN顯示器相比,IPS顯示器上的平行偏振片對準是可以從極端角度觀看它們的原因之一。同時,TN顯示屏默認情況下允許光線通過的方式(不施加電壓來破壞流量)是TN顯示屏比類似IPS型號具有更快的響應時間和刷新率的原因之一。

我需要IPS嗎?

您對IPS技術的需求取決於您如何使用筆記本電腦顯示器或獨立顯示器。這是IPS和TN顯示器相對優勢的簡要介紹。每種類型如何滿足您的要求?

  • 適用於家庭和家庭的大而明亮的聯想監視器
  • 思維中心監視器(小巧的觸摸屏)

IPS顯示器和IPS顯示器的優勢

IPS顯示和監視器具有以下幾個優點:

  • 較寬的視角:IPS顯示器的晶體和偏光鏡的平行方向使它們從極端角度更容易觀察,例如用於大團體觀看。只有最靠近顯示屏側面的人才能看到顏色和對比度的任何大幅度降低。
  • 顏色種類更多:大多數IPS顯示器均具有8位面板(紅色8位,綠色8位,藍色8位),因此它們可以更好地再現典型圖形處理器的完整24位調色板(8 x 3 = 24 )。許多TN顯示器具有6位面板(6 x 3 = 18),並使用額外的步驟來模擬整個色彩範圍。
  • 更高的色彩精度:IPS顯示器的製造價格通常比TN顯示器更高,並且使用能夠產生更寬色域的更好的背光(例如Adobe RGB與較舊的sRGB)。附加的色調和陰影可提供更逼真的逼真色彩。

與TN監視器相比,IPS監視器的一個缺點是刷新率(重新配置每個屏幕上的圖像所需的時間)和響應時間(像素從活動狀態變為活動狀態時的延遲)相對較慢。但是這些延遲的測量單位是毫秒,因此絕大多數用戶(例如,除高級PC遊戲玩家以外的所有人)都不會受到影響。IPS足夠快,足以用於流電影,進行視頻通話等。

多功能LENOVO平板電腦具有 IPS顯示屏,而且:

  • WINDOWS 平板電腦,包括THINKPAD和MIIX系列模型
  • Android平板電腦如製表系列和瑜伽TAB系列

TN顯示器和TN監視器的優點

儘管IPS顯示器的市場佔有率不斷增長,但TN技術仍然有專用的用戶群。原因如下:

  • 更快的響應時間和刷新率: 如上所述,TN顯示器的特性使其刷新屏幕上的圖像並激活/禁用每個像素的速度更快。雖然差異只有幾毫秒(最好的TN面板擁有高達1毫秒的響應時間-比高端IPS型號快2-3毫秒),但有競爭力的PC遊戲玩家通常希望最快的刷新率和響應時間。
  • 更低的價格(通常): TN顯示器的價格要比具有相同分辨率,功能等的IPS顯示器便宜,這已被廣泛接受。但是,價格差異隨著時間的推移逐漸縮小,一些IPS顯示器的價格現在為200美元或更低。不過,要警惕價格太便宜的IPS顯示器。一些用戶抱怨低端IPS顯示器上的所謂“ IPS發光”,背光在屏幕的某些部分顯得比其他部分更亮。

準備購物?聯想提供全系列的筆記本電腦平板電腦,獨立顯示器以及具有不同顯示技術的一體機。現在您知道IPS和TN的顯示方式有何不同,您就可以做出選擇了。
