On 25 October, at Peking University Gymnasium, Xiaomi launched Mi Note 2. The smartphone inherited the design from the Note series and fulfilled the wishes of all Xiaomi fans in terms of hardware. One of the goodies of the device is the OLED screen, but what is special about it?
The strengths of an OLED screen compared to an LCD are:
- Lower thickness (1 / 3 than that of an LCD) and lower weight
- Solid, non-liquid, shockproof
- Larger viewing angles, clearly lower distortion
- Lower response times, no dulling
- Display possible even at -40 ℃
- Greater color gamut and contrast, no luminance for black
- Greater efficiency with high brightness, reduced consumption
- Manufactured on the basis of different materials that allow the creation of curved displays.
OLED screens, however, have drawbacks. The cost of a normal flat screen of this type is high (even if it is the same as a high end LCD) and is closely related to the resolution. Most OLEDs don't use the classic RGB layout (Samsung's OLED takes advantage of the PenTile matrix for example). The LCD screen is a glyph “田” (Tian) with pixels arranged horizontally and vertically, while in OLEDs the pixels are perpendicular to the diagonal. This gives the impression of having jagged edges when viewing text with a pixel-per-inch ratio that is too low. The only way to counter the weaknesses of OLED screens is therefore to increase the resolution.
Mi Note 2 is equipped with a 1080 ″ 5,7p OLED screen provided by LG. While the display quality is excellent, there is some room for improvement. The minimum brightness, during the night hours, is still dazzling, the viewing angle is not the best and there may be cases of partial loss of color when looking at the screen from the sides. The Note 2's screen is still the first curved OLED to be mass-produced by LG and it's understandable that the result isn't perfect.
But so I did not understand: is PenTile matrix or RGB matrix?
