The high resolution of 8K screens means you can stand very close to them without seeing the individual pixels
Although several companies have developed “super hi-vision” resolution test models, this is the first such TV to be made commercially available.
The 8K format provides 16 times as many pixels as 1080p high definition. It creates an image so detailed that it can appear three-dimensional.
However, the 85in device’s 16m yen ($133,000; £86,000) price is likely to limit sales.
Interest is expected to come mainly from broadcasters and other companies involved in testing the format.
One analyst suggested it would not become a serious proposition for members of the public until the turn of the decade.
Japan’s NHK is the only broadcaster so far to announce plans to create and broadcast 8K content.
Japan’s a region in which the average size of TVs sold tends to be smaller, and we think the minimum size 8K TVs would be sold at would be 65in.
So for the time being, he expected manufacturers to focus their efforts on trying to convince families to buy 4K sets instead.
They provide a quarter of the resolution of 8K, but are being made in sizes of up to about 100in to create “cinema-like” experiences in the home.
Due to technological restraints, owners of Sharp’s LV-85001 will have to use workarounds to take advantage of its full capabilities.
Its built-in TV tuner cannot actually receive broadcasts in 8K. Instead, video has to be fed in via four separate HDMI cables, which are needed to handle the quantities of data involved.
The resulting image delivers 104 pixels per inch.
That is about a fifth of the density of modern high-end smartphone displays, but is more than enough to allow people to read relatively small-sized text or make out intricate details when standing close to the screen.
