請問 LCD TV 1080i 及1080p 的分別?

The frame resolution is the same 1920x1080 but

Resolution
1080p = 1920x1080 = 2.07M pixels per field

1080i = 1920x1080/2 = 1.04M pixels per field

i= interlace display show 50 field per second, 2 field makes up of 1 complete frame (ie. one full image), only 30 full resolution frames per second
p=progressive display show 50 full frame per second

In simple terms, 1080p shows more details than 1080i and looks much better.

i係隔行掃描,p係逐行掃描.

現時LCD TV輸入端子只有色差和HDMI兩種可以支援

1080i和1080p.

當訊源以1080i輸入TV時,會將畫面分為橫向1080行,然後

第一次只顯示單數橫行,第二次會顯示數橫行,第三次又

顯示單數橫行,如此類推.

當訊源以1080P輸入TV時,每一次都會所有行數掃描顯示.

故此理論上隔行掃描會出現輕微閃爍現象,情況就好似電

燈的閃爍一樣,人類視覺很難看得清楚,但觀看時間長就會

容易疲倦.

１０８０ｉ係「格」行ｓｃａｎ
１０８０ｐ係每行ｓｃａｎ
