The high-end devices of the Samsung and LG brands follow in the tests of the Awaqa, this time we compare the screens with competitors Galaxy S8, LG G6, iPhone 7 and Galaxy S7. After comparing cameras, now we know which model offers the best quality display.
In order to obtain the screens of the devices mentioned above, knowing the best balance in terms of the level of brightness, contrast, saturation, index of reflections in the glass covering the screen and visual fatigue, we use the following standard of evaluation:
Display and compare the same group of five images used in other screen comparisons made by the All-Mobile, being divided into three stages:
- Sunny external environment
- Indoor environment with artificial light
- Inner night atmosphere
In the case of the sunny external environment, we use the devices with the maximum screen brightness allowed, so we have an idea of how the devices leave when facing excessive lighting.
In the indoor test with the artificial light, we manually level the screen brightness of all devices to 200 lux, possible solution thanks to the use of a digital lux meter. Thus, in this test, we basically compare the color fidelity and the contrast of each one of them.
And to close this stage we have the test in the dark, in which we try to show which screen reaches the highest brightness, as well as which device offers the lowest brightness, helping to reduce visual fatigue. We also put all devices with brightness at most in this scenario, to evaluate the difference of each screen.
As we can see in the table above, the models have a screen between 5.1 and 5.8 inches, with resolution ranging from 750 x 1334 pixels to QHD of 1440×2960 pixels. Regarding panel technology, Galaxy S8, and S7 adopt Super AMOLED technology, while both the iPhone 7 and the LG G6 were equipped with IPS LCD. But without further ado, check out the comparative results below.
Sunny environment (direct sunlight)
For those who want to use the smartphone outdoors in direct sunlight, the best option among comparative models is the Samsung Galaxy S7. The Super AMOLED technology proved superior to the IPS LCD because the second best was the Galaxy S8, followed by the iPhone 7.
However, it should be noted that the light colors on the front of some devices, such as the Galaxy S7 and iPhone 7 used in the test, should also cause some discomfort when reflecting more sunlight. The recommendation is to avoid models with clear frontals and with the very strong mirror effect, at least for this type of use under the star king.
Indoor environment with artificial light
In the test indoors with artificial lighting, we realize how much more pleasant is the bet in dark colors to the front of the smartphone, making the consumption of content on the screen much more intense. Hence the advantage of the Galaxy S8 and LG G6 models in this regard.
All four models are good quality in a sunlit environment, but it is important to note that the Super AMOLED technology offers the better contrast with more “vivid” (saturated) colors, while the G6 IPS and the iPhone 7 LCD display color More faithful, but with a blackish gray.
Inner night setting (maximum brightness)
By completely eliminating external illumination, it is easier to isolate screens from devices to better understand the differences. With maximum brightness in a completely dark environment, we see that the Galaxy S8 offers the strongest brightness among the challengers (sold by the lux meter below), being accompanied by the S7 and the iPhone 7.
Contrary to what many might judge, the LG G6 here could be considered the best option in terms of more moderate brightness to avoid visual fatigue. On the other hand, while compatriot rivals allow regulating the clarity for less with better contrast, the G6 can not go beyond.
Inner night environment (brightness at least)
And finally, still in the test in the dark environment, but with the screen brightness set to the minimum, we see that there is almost a general draw. The G6 has a bit more difficulty in reducing the brightness to the maximum possible.
The data collected with the lux meter shows that while at the minimum brightness with a black image the four devices have the result “zero”, when the image is white the LG model jumps to “3”, against “2” of the other embayments. These results make clear the difficulty of the G6 in making it even more comfortable for the eyes to use in unlighted environments.
With the help of a digital lux meter, we have recorded some concrete parameters of comparison, choosing a completely black and a completely white image to measure the maximum and minimum level of brightness of the devices in the display of both.
The data below are measurements made on the lux unit, which measures the intensity of light emitted from the screen of each device:
Maximum brightness of black image
- Galaxy S8 – 0
- LG G6 – 1
- iPhone 7 – 2
- Galaxy S7 – 0
Minimum brightness with black image
- Galaxy S8 – 0
- LG G6 – 0
- iPhone 7 – 0
- Galaxy S7 – 0
Maximum brightness with white image
- Galaxy S8 – 780
- LG G6 – 530
- iPhone 7 – 705
- Galaxy S7 – 739
Minimum brightness with white image
- Galaxy S8 – 2
- LG G6 – 3
- iPhone 7 – 2
- Galaxy S7 – 2
With the numbers properly collected, we realize the superiority of the Super AMOLED screen, present only on Samsung models.
For those who want to use the smartphone in bright environments, according to the results of this comparison of screens, is the technology Super AMOLED present in the Galaxy S8 and S7 models. In dark environments, we continue with the previous indication but adding the iPhone 7.
For those who consume many videos and games, the contrast of Samsung smartphones is a very nice extra, in addition to the saturation that makes the experience more intense. That’s not to say that the LG G6 is bad, far from it.
The differences between the four models evaluated are small, and because it is a comparative of screens we can not fail to recognize that the frontal exploitation, united with the black edges (of the units acquired by the Cellular Tudo) make the Galaxy S8 and the LG G6 as Our indications, in the order cited.
