嗯 你還是沒搞懂....
站長是懂的 可能你問站長會比較快
我感覺我在說明的 你都找相反方向去看
So, how good are 8K TVs compared to traditional TVs? Let's compare them to Full HD TVs and 4K UHD TVs to find out.
The resolution in 8K TVs is 4 times higher than that of 4K UHD TVs, and 16 times higher than Full HD TVs. Higher resolution means that there are more pixels that make up the screen. In other words, on the same size TVs, pixels are more densely packed within the same area which allows for a much more sophisticated and realistic image representation. This provides an overwhelming sense of immersion when you watch TV.
The term used to describe the number of pixels in a given area is called PPI (Pixels Per Inch), and naturally a higher PPI number means higher pixel density. Typically, PPI should be at least 50 or more in order to enjoy various kinds of video content. That being said, on a 75"" 8K TV the PPI is 117 while on a 4K TV and FHD TV it's 59 PPI and 29 PPI respectively.
這是你貼的網站連結 下面的一段就有提到
而ppi dpi 都是指解析度
在 8K電視上,PPI為117,而在4K電視和FHD TV上,PPI分別為59 PPI和29 PPI。
ppi越高代表越清析 |
