Among them, sitting on the halo of the tenth anniversary of the iPhoneX with the biggest difference between other models is the configuration of the OLED full display screen, while the iPhone 8, iPhone 8 Plus still configure the traditional LCD screen.

It should be said that the so-called OLED display screen for Apple is still a very new technology. But OLED screens have long lost their freshness to anyone who has been exposed to Samsung's phone, Google's Pixel or Andy Rubin's new Essential device. Even Samsung was already using OLED screens as early as seven years ago when the first generation of Galaxy models was introduced


What is the OLED screen?


OLED is called "Organic Light-Emitting Diode" (Organic Light-Emitting Diode), is an organic self-luminescent material, which makes OLED screen no longer need backlight module, so the thickness can be made thinner. Moreover, OLED also has a wide color gamut, almost infinitely high contrast, high response speed, bendable, energy-saving features, it is also known as the "fantasy display technology," the title.


And, thanks to the self-luminous nature, the OLED screen does not emit any light at all when displaying black, and the LCD still needs backlights to operate in the background even when displaying black. The most direct effect of this mechanism is that the OLED screen can display the perfect picture contrast, the display will be more vivid and real. The most direct contrast is that if you put a Samsung GalaxyS8 and iPhone 7 together, you will find that although the iPhone 7's display has been good enough, but the OLED screen Galaxy S8 is still better.


Moreover, the OLED screen can be made into a curved screen. The reason why the model such as the Samsung S8 is a curved screen is due to the adoption of an OLED screen, and the LCD screen does not support bending due to the characteristics of the liquid crystal. Another reason for Apple to choose OLED screen may be that the current in-screen fingerprint recognition technology only supports OLED screen, because the screen fingerprint flex can be done with the screen flex together.
