優派發表120Hz的液晶顯示器
文章分類: 顯示螢幕
我們桌上型顯示器,一般的頻率為60Hz,在之前美國舉辦的N VISION 2008大會上,優派推出了120Hz倍頻液晶顯示器。當然,廠商宣稱「與傳統液晶螢幕每秒60Hz的掃描率相比,120Hz超倍頻液晶螢幕擁有多出2倍的掃描次數,同時也是電影影片每秒24格播放速率的5倍頻率掃描,反應速度快,能有效抑制動態影像殘影,還原出來的影像更加清晰、逼真與穩定,色彩豐富豔麗,長時間觀看也不會疲勞,排除了任何細節被丟失或模糊化的缺失。」是不是這麼讚,我不知道,畢竟我也沒看過倍頻技術的LCD表現。不過個人有請教過曾經看過同一塊LCD面板,一邊是用60hz,另一邊是用120Hz的老師。他跟我提到,比較起來,影像邊緣表現會比較明顯,效果的確會比較好。不過120Hz用於液晶電視較多,顯示器倒是沒有什麼聽過(當然呀,老師,我問你的時候,這款才剛曝光)。
據廠商說明,預計年底上市。

NVISION現場實況,依國外網站所提,當時是採用 NVIDIA dual-link DVI輸入,並支援3D鏡呈現3D效果。(依手中新聞稿所提,這3D影像顯示技術,為NVDIA所開發,圖中不知為何,有一個人沒戴XD)

120Hz的液晶電視不只 Sharp,還有:
# Sony - MotionFlow 120 Hz
# Samsung - Auto Motion Plus 120 Hz
# Philips - HD Digital Natural Motion
# Hitachi - Reel120
# Vizio - MEMC (Motion Estimation, Motion Compensation)

相信是有分别的吧,普通的萤幕60Hz和70Hz的差别已经很大了。60Hz一直闪烁,而且色泽有点暗淡;相对之下,70Hz的明亮很多了。

液晶螢幕的光源是連續光源,所以不會有Hz更新頻率的閃爍問題......
現在的120Hz的更新率,我想因該是噱頭大過於實際功能的一個特點吧......
其實文中說到120Hz的螢幕會比較銳利...那不如乾脆說用了120Hz的螢幕可以讓人身高變高,身體變壯,腦筋清晰,考試都考100分......

LCD 的更新頻率(Refresh rate) 請參閱 Wiki:
"Much of the discussion of refresh rate does not apply to the liquid crystal portion of an LCD monitor. This is because while a CRT monitor uses the same mechanism for both illumination and imaging, LCDs employ a separate backlight to illuminate the image being portrayed by the LCD's liquid crystal shutters. "
" The closest thing liquid crystal shutters have to a refresh rate is their response time, while nearly all LCD backlights (most notably fluorescent cathodes, which commonly operate at ~200Hz) have a separate figure known as flicker, which describes how many times a second the backlight pulses on and off. "
" However, the lower scan rate can introduce more flicker on high speed motion, so sets that use digital technology to double the refresh rate to 100 Hz are now very popular. "

記得主要是指畫面更新速度在120hz下,剛好在每秒24張的Movie與每秒30或60張的遊戲或一般影片播放下,都可以整除,不會遇到需補間畫面造成不順暢的問題,日系新出較高階的LCD或PDP幾乎都有這個功能說 ~

終於不用再忍受60Hz螢幕的閃爍了....看得我好痛苦阿~.~

是我眼拙嗎...
我倒是沒看過LCD會閃的
CRT倒是閃到頭會暈

這時可以發現木眼跟木耳
其實是幸福的 :)

120hz? 它的反應是幾ms需要用到120hz啊?
