Nobody knows how much the rollable TV will cost, but we can look at some past pricing from LG to make an educated guess at the range. The LG Signature OLED TV W8 is currently available in both 65-inch and 77-inch models, and both are so-called "Wallpaper" televisions but don't roll up. That line of TVs starts at around $7,000.
The big difference here is that the LG Signature OLED TV R rolls up into a stylish little rectangle, and that difference is certain to cost a significant amount of money. How much of a difference it is remains to be seen, and LG isn't saying just yet.
That it's essentially a TV stand, TV, and soundbar all-in-one is sure to add a few more dollars to the bottom line.
It's not clear exactly when these will go up for sale, but they're part of the 2019 line-up from LG.
