Retinal display screen is not simple. It uses the principle of human visual persistence to make the laser scan quickly in the horizontal and vertical directions according to the specified order, and finally hits a small area of the retina to make it feel the light, thus making people feel the existence of the image. With the birth and application of this technology, people will reduce a series of eye and nerve diseases caused by staring at the screen of electronic equipment such as computers for a long time.
However, because the price of LCD is relatively high, and the computer made of LCD is very light, with little eye injury and little radiation, the price of this computer is still relatively expensive. But this is exactly in line with the unique style of the iPhone. Not only does it sell high cost performance, but it also sells his unique design, which gives people a sense of sight as a whole.
