    為什么我們要關閉屏保

      屏幕保護程序設計的初衷不是為省電,也不是為了好看,而了為了保護電腦的CRT顯示器的硬件壽命而設計的。下面是學習啦小編為大家整理的我們為什么要關閉屏保,希望大家能夠從中有所收獲!
     

      為什么我們要關閉屏保?

      很多人從一開始使用電腦時,都喜歡使用屏幕保護程序,直到現在大多數人都在使用筆記本和液晶顯示器了,這個“好習慣”也被保留了下來,但很多人卻不知屏幕保護程序對筆記本電腦和液晶顯示器,非但沒有好處,反而還會造成一些負面的影響。

      實際上屏幕保護程序僅對CRT顯示器有保護作用,而對于液晶顯示器它卻只能幫倒忙。這是由于液晶顯示器和CRT顯示屏的工作原理不同引起的。

      原來我們使用的CRT顯示器,當用戶停止對電腦進行操作時,屏幕顯示就會始終固定在同一個畫面上,長時間下去,會因為導致屏幕老化,甚至是顯像管被擊穿,因此從Window3.X時代至今,屏幕保護程序一直作為保護CRT顯示屏的最佳幫手,通過不斷變化的圖形顯示,避免屏幕的損壞。

    為什么我們要關閉屏保

      但對于液晶顯示屏,即LCD,由液晶分子的開關來控制圖像的顯示,開關次數越多,損耗越大,因此當我們對電腦停止操作時,還讓屏幕上顯示五顏六色反復運動的屏幕保護程序的話,無疑使液晶分子仍處在反復的開關狀態,這將加速消耗LCD的使用壽命,容易出顯老化,壞點等現象。所以,不同的顯示器,要使用不同的保養方法。

      從節能的方面講,更應該關閉屏保,現在更多的屏幕保護程序制作者過余注重圖像的表現力以及色彩的變幻,已經完全將屏幕保護程序當作一個動畫來制作,有些甚至是3D即時處理的動畫,還需要圖形處理的配合處理,因此很多精美且體積龐大的屏幕保護程序便應運而生,如些的屏幕保護程序固然能夠給觀賞者以視覺上的享受,但是此時對于電腦內在的硬件來說,卻成為了累贅,這和屏幕保護程序讓電腦硬件休息的設計初衷嚴重背離,由于需要應付不斷變化,且色彩細節豐富的屏幕保護程序,CPU,硬盤和顯卡的工作負荷可能比平時一般的應用還要高,對于有時會使用電池供電的筆記本電腦來說,這個時候這樣的屏幕保護程序無疑成了電池消耗大戶。因此使用液晶顯示器和筆記本電腦的用戶,請不要使用屏保。

      當然,不管你是使用的什么顯示器,當你可能會在一段時間離開你的電腦時,尤其是在使用電池供電時,關閉顯示屏才是你唯一正確的方法,然而如何關閉顯示器,你有很多種方法來實現,但對于大多數用戶來說,操作起來,可能比較麻煩,又或是忘記操作,怎么辦呢,那就把這一切交給魯大師來完成,魯大師處處為用戶考慮,會自動幫用戶完成這些操作

      不要被漂亮的屏幕保護所迷惑,為了更好的保護你的液晶顯示器,請讓它們遠離你的筆記本電腦!
