The optical system and method for realizing zero frame display is a patent application recently exposed by apple. Among them, apple continues to explore ways to narrow the borders of iPhone and MAC screens. On devices from Apple watch to Mac, there’s a reason we don’t have a real border to border display. Although they can be implemented in different sizes of the screen bezel or control circuits, they can still be implemented in different sizes around the screen. < / P > < p > Apple said in its patent that electronic displays usually include a frame around the display, which can be used to hide the driver circuit used to operate the display. However, the use of such a frame will reduce the overall visible space of the image. Apple came up with two ideas to reduce the border. < / P > < p > first, the border or border area can be covered by the passive part of the display. It may not respond to touch and does not have all the functions of the main display, but a light tube can route some images to this area. The function of the light tube may be to transmit or distribute the light of the pixel array to, for example, a driving circuit area to produce a perceived active region. < / P > < p > Second, pixels in this area can be further spaced than other parts of the display. This will allow the display pixels not to obscure Apple’s drive circuit. In this way, the pixel spacing (i.e. the distance between pixels) of the boundary region is increased relative to the pixel spacing of the active region pixels. In other words, red, green and blue pixels are interspersed between the drive circuit elements. Didi Qingju bicycle has entered 150 cities
