We have already spoken many times of the importance of the screen to a device. And in this regard, Samsung has managed to establish itself as best manufacturer of screens. Samsung usually publishes OLED 2 generations per year, every 6 months, so there is a performance boost in each evolution. And the new Galaxy Note 4 and the series Galaxy S are attempting to South Korea to show its improved OLED screens.
But not everything is there, DisplayMate, displays real experts assure us that there has been significant improvements in display performance .

At this point, with respect to the Galaxy S5, the more substantial improvement is in pixels per inch resolution . with resolutions Quad HD 2560 x 1440 pixels with 518 pixels per inch for 5.7 inch Note. With this, you get a sharpness much higher than before, going from the Galaxy S5 MP 2.1 to 3.7 of this model. This type of pixel density is called Diamont Pixels.
Regarding the Galaxy Note Edge , is similar but made of a flexible plastic substrate, to get that bend in the screen. In this case, the density is 2560 x 1440 , to be managed by software as two separate screens: a 2560 x 1440 and a 2560 x 1600 . Both are accompanied by Gorilla Glass 3 technology for added protection.
Another important aspect is the absolute color accuracy. In this way, the user has an application for Color Management , offering a series of screen modes with varied palettes. For example, we have four Galaxy Note 4 modes :
- AMOLED photos : Use very precise with standard calibration Adobe RGB color (17% larger than sRGB). It is the most realistic of all modes, approaching more cameras
- AMOLED movie
- Adaptive Display .: With real-time adaptive processing to dynamically adjust images and video. It can cover 130% of the sRGB standard. The colors are more saturated and less realistic
- mode basic screen . Provides a very accurate sRGB for color, covering 101% of the sRGB standard
Regarding the Brightness , the Galaxy Note 4 can reach much higher levels when auto brightness is enabled. This gives us a better visibility to ambient light. In fact, lets just turn down the brightness to 2 nits , which we note especially at night. But also has a Super Dimming so as to allow the brightness setting down also useful to work without eyestrain in very dark environments.
Higher resolution does not mean worse consumption
Another very important fact and of great concern is the energy efficiency , affecting directly to the battery. In this case, it shows a improvement of 14% with respect to the Galaxy Note 3 . But this value is quite striking, as we have almost twice the number of pixels, so that the processing overhead is much higher. It also has a new power saving mode which lowers the brightness and set the background to black.
Beyond that, a way to determine the quality a screen is to analyze viewing angle . In this respect, the new Note has a decrease much lower brightness at 30 (angle view where usually experience greater decrease in brightness), which is around 19% lower. His predecessor, had a brightness reduction of 55%, so the difference is obvious.
Conclusion
This leads us to see how Samsung continues to lead the manufacture of screens, and have not been resting on their laurels far. For they have not only gotten the OLED performance flexible plastic substrate is the same as in glass substrate traditional , but have improved the resolution and pixel density, and a substantial improvement in brightness and viewing angle .
In addition, the color management is much more complete and accurate , now we even have modes. And all accompanied by a optimized energy efficiency . And it is for these things, the Samsung podium remains, at least for now.
