BENQ 低價4K...(恕刪)
剛看到W170的售價還蠻震撼的. 這樣不知道UHD60/65有甚麼優勢可以賣到兩倍價?
Operating at a very high speed, this new 1920x1080 chip can put all of the original pixels in each 4K frame on the screen, though not simultaneously, by flashing 4 times per frame, with each flash showing one-quarter of the pixels. Like the 0.67 chip, which has twice the number of pixels as the 0.47 and only needs to flash twice to get all of the roughly 8 million pixels in a 4K source onto the screen, the 0.47 design employs pixel shifting.
0.47 是 1920 x 1080的晶片，單一晶格快速反射4次，在投影幕上呈現4個晶格，藉此產有800萬獨立畫素在投影幕上
至於DLP與3LCD的差異，可見對岸的文章，我覺得寫得很詳細

但重點不該注意規格上的迷思，而是實際看到的效果
因為像鏡頭、光機等等
這些會影響畫面的零件，是規格表上面看不到的
