In comparison to other technologies, which type of smartphone display has fewer layers and thus provides more flexibility, a better viewing angle, and excellent color?

OLED displays are used in many newer smartphones because of their light weight, flexibility, color depth, and wider viewing angle. IPS is a type of LCD (Liquid Crystal Display) that uses backlighting to display images. The first LCD technology developed was TN. It consumes less power and has a narrow viewing angle, but it supports extremely high refresh rates. LEDs can be used as LCD system backlights. Because their carbon-based material can emit light and color, OLED displays do not require a backlight.
