Vivo has officially announced one of the secrets of X5Max's ultra-thin design - single-sided critical layout. We know that the mobile phone's screen also accounts for a large part of the thickness of the body. According to the latest internal news of Vivo, the X5Max will use the Super AMOLED screen.

At present, the screens on smart phones are generally divided into LCD and OLED according to the material. LCD is represented by TFT, and the most representative OLED is Super AMOLED.

Among them, LCD, namely liquid crystal display, is a kind of display that uses liquid crystal control transmittance technology to achieve color. However, since the liquid crystal material itself does not emit light, the LCD must be equipped with a backlight module to provide uniform background light source, which leads to the LCD screen is generally thick, so as long as it is ultra-thin smart phones will generally give up the LCD screen and use OLED screen.

In terms of technology, OLED only needs two layers of film and glass or plastic substrate, which is simpler than LCD technology, and its display effect is brighter and more delicate than LCD. And because OLED has self luminous characteristics, it does not need backlight module, color filter and liquid crystal filling process, so it not only saves power, but also can be made very thin.

So it is very reasonable for vivo X5Max to choose OLED screen. In terms of production technology, vivo X5Max has its own technology. It is understood that the ordinary full OLED screen is at least 1.4 mm thick, which is still a bit thick for the thin smartphone, so vivo customized the vivo X5Max screen to Samsung, and adopted new technology on the panel, reducing its thickness by at least 0.05 mm, thus compressing its thickness to below 1.36 mm, becoming one of the thinnest screens in the industry at present.

Although the material has been compressed, the quality of vivo has not decreased at all. The world's thinnest OLED screen on vivo X5Max can reach the minimum color saturation of 85% and the center value of 100% in the test based on CIE1931 standard colorimetric system. This data is far beyond the industry standard, which is enough to prove that the world's thinnest OLED screen on vivo X5Max is one of the best OLED screens at present.
