The reason why a curved display with a screen ratio of 2 1:9 is called a fish screen can also be listed. For example, the screen with a fish screen is slender, and the screen ratio of 2 1:9 makes it have wider screen vision and more immersive experiences. For example, the HKC C299Q fish screen has a wide screen vision, which makes it easier to take the lead in playing games and can be split into multiple screens.
