How to evaluate EINK auxiliary display PaperLike

The resolution of PaperLike is 1600* 1200, and the clarity is the same as that of DPT-s 1. The size is the same, and EINK suppliers are all estimated to be one. DPT-s 1 is nearly 6000 yuan, so it can't be used as a monitor (unless it is cracked, it will be very troublesome). This will be mass-produced soon, and the price is 4999. Not expensive, although not cheap. For students who often write and read papers, this is necessary to protect their eyes. Looking at the LED screen for a long time does not hurt the eyes by 5000 yuan. It's just that 13.3 inch is a little small, so there is no way at present, and the supplier doesn't have a 20 inch one. I think the replacement can be faster in the future, and then a 20-inch screen can be produced (the resolution can be unchanged), and the price will gradually drop from high-end users to mid-end users, and the price will drop to about 4000. More and more people will fall in love with this screen.
