A detailed comparison of screens iPhone 6 / Plus with iPhone 5 / s
Makradar Ios / / December 22, 2019
Dr. Raymond M. Soneyra, president of DisplayMate Technologies, wrote awesome article, Which conducted a detailed analysis of the characteristics and technology used by Apple to manufacture displays for its new flagship, compared with the iPhone 5 and the existing competitors. Dr. Sauniere also spent an incredible amount of laboratory tests, with a description and the results of which you can read in our translation.
introduction
At all times, a key element of a successful smartphone is an innovative and high-tech displays that always adorned the flagship high-end manufacturers. IPhones and iPads Apple, until recently, remained at the top of technological progress: they appeared very early high-performance IPS LCD, transferring 100% sRGB gamut and 24-bit color. Steve Jobs and Apple in general, have always paid a lot of attention as a display to promote their products.
iPhone 4
The most aggressive Apple innovation was Retina-display iPhone 4 which was twice increased resolution and pixel density (ppi). It was a brilliant technical and marketing ploy that left the competition far behind.
iPhone 4s, 5, 5s
But after, iPhone displays innovation slowed down and came to naught: in 2011, the iPhone 4s the display remains the same; in 2012, the iPhone 5 display was extended color gamut sRGB, and up to 100% has been increased to four inches; Display iPhone 5s in 2013 remained the same.
Rivalry
While the development in the field of displays, Apple innovation has slowed down, while other manufacturers are working in this direction, trying to take the lead. Now Amazon, Google, HTC, Huawei, LG and Samsung are using in their products better and more innovative display than Apple. Take for example displays new iPad mini Retina, colors which have been reduced from 100 to 63% (in Compared with earlier Apple products), because of what it takes is not the best place among competitors.
iPhone 6
Now, in 2014, four years after the release of iPhone 4 Innovative, nice to see again improved display in the iPhone 6 and iPhone 6 Plus. However, Apple a lot to make up for the last four years, as competitors are not sitting back and now on the market are many smartphone with Full HD LCD- and OLED-displays.
About sapphire
The use of sapphire in the manufacture of the iPhone display to provide protection against scratches was perhaps one of the most popular rumors. However, the likelihood of sapphire display iPhone 6 was close to zero, since the "break-in" technologies will take at least a year. In addition, the sapphire has shortcomings in addition to the high cost and complexity of manufacture. The biggest problem is it - is that it increases the reflection properties almost doubled, so the sapphire display will be very difficult to read in natural light. This is one of the reasons that in the Apple Watch Sport Edition used displays of ordinary glass, because most of the time they will be used outdoors. Another reason - a high hardness of sapphire stone, and as a consequence, a great fragility and susceptibility to fracture of the bumps that are inevitable when doing sports.
testing methodology and conclusions for each section
Research is conducted on the basis of extensive laboratory tests and extensive visual comparisons using the standard test photos and patterns.
Display resolution and PPI
iPhone 6 and iPhone 6 Plus equipped with a Retina-displays, which implies that when using a normal distance of pixels to be indistinguishable to the human eye with a 100% vision. iPhone 6 has substantially identical display as the iPhone 6 Plus, with the only difference that has minimal resolution and the total number of pixels - it just 1.0 MT 2.1 MT against the iPhone 6 Plus (and 2.1-3.7 MT as in the existing competitors). This point should not be underestimated, since the total number of pixels is very important, especially for the display of photos and images with higher resolution than the native resolution of the device. The same high-resolution photos (more native) look better on the iPhone 6 Plus, but even a relevant resolution photos look better on a larger iPhone 6 Plus. Most people are able to notice the difference, and for them the best choice would be iPhone 6 Plus.
Full range of support sRGB and absolute color accuracy
Nice to see that the new iPhone back to 100% support the sRGB, once in the iPad mini Retina, released in 2013, it was reduced to 63%. Both the iPhone is very accurately convey the sRGB-scale, which is used to display the vast majority of digital content in the cells, HDTV, Internet and computers.
To ensure absolute color accuracy need accurate scale saturation and white point. Both the iPhone 6 have an accurate with the saturation index of 2.22 range, but slightly offset the white dot in them ( towards the blue) with a color temperature of 7.300K, that is a very good result and it is better than iPhone 5.
Screen brightness and work in natural lighting
Mobile displays often operate under a relatively bright ambient light, which greatly reduces the color and contrast of the image, reducing the quality and making it difficult to read. In such cases it is very important two things: the display brightness and glare nonsusceptibility - the iPhone 6 and 6 Plus have both. Their displays provide a brightness of over 550 cd / m², which exceeds the result of all the smartphones that we've ever tested, and significantly higher Full HD smartphone from the line in 2013.
The reflection coefficient displays both iPhone is 4.6%, which is very close to the ever measured our results in Full HD smartphone with LCD-display.
Excessive displays characteristics
Displays all test iPhone we had almost the same characteristics of brightness, contrast, gamma, saturation, and total calibration. This is very unusual, and this can happen only if the detailed automated calibration performed on each individual display at the factory.
But the most surprising is that all the features of the claimed exceed 10-13%. For the iPhone 6 and 6 Plus display brightness is listed as 500 cd / m², but in reality it is 558 cd / m² for the iPhone 6 and 566 cd / m² - for the iPhone 6 Plus. We have a "reserve" of 12%. The same applies to the claimed contrast, Apple points to 1: 1400 for the iPhone 6 and 1: 1300 - for the iPhone 6 Plus, but in fact the real value is 1: 1591 and 1: 1451 respectively. That is about 13% of the stock in both models, and the highest value among the measured contact ever in mobile displays.
Energy display
iPhone 6 and iPhone 6 Plus have about the same power consumption as the iPhone 5, which is not surprising, because all of them board displays have low-temperature polysilicon, which are currently the most energy-efficient. They are 10% more efficient than all LCD-displays that we've ever tested, but the reason for this - different pixel density (PPI).
If we compare with OLED-displays, the LCD is generally more energy efficient for images in which the content is made up of white flowers (for example, text display). OLED, on the contrary, show themselves well when displaying mixed content, as they are emission and power consumption depends on the average level signal (color images), while the LCD-displays consume the same amount of energy regardless of the level signal.
When displaying the mixed content including images, videos, movies, with an average signal level (about 50%) - OLED-display Galaxy Note 4 proved to be 21% efficient iPhone 6 and iPhone 6 Plus. On the other hand, when the content is displayed with 100% signal level (white display), leader was iPhone 6 and iPhone 6 Plus, showing a 45% better result.
viewing angles
Despite the fact that smartphones are the individual device and only have a "viewer", viewing angle displays are still important because users often are kept them from different angles. Typically, this angle is about 30 degrees (or more if the device lies on the table).
Viewing angles iPhone 6 and iPhone 6 Plus is much better than the iPhone 5, and any LCD-displays that we've ever tested. Particularly important are the high values of contrast, and a small drop of brightness when changing the viewing angle.
visual tests
iPhone 6 and iPhone 6 Plus provides a very nice, pleasant and accurate color and image quality. Despite the fact that the white point is (intentionally) a bit overpriced toward blue, absolute color accuracy and saturation are at an excellent level.
The final grade iPhone 6 and iPhone 6 Plus: great mobile displays
The main goal of all tests DisplayMate Technologies is to determine the manufacturer and display technologies that are at the top of progress. Based on extensive tests and a thorough and comprehensive analysis, we find out who is in the lead of the manufacturers who are left behind, who improved technology, and who (unfortunately) inhibits them.
iPhone 6 Plus
Displays iPhone 6 and iPhone 6 Plus have the best displays among ever tested smartphones with LCD-displays. With this iPhone 6 Plus is the second smartphone (among LCD, and OLED) in the history (since 2006), the display of which received a "green" evaluations (from "Very good" to "excellent") in all evaluated categories (except the indicator brightness fall when you change viewing angles, which is typical for LCD-displays). This in itself is an impressive achievement for the display.
iPhone 6 Plus equaled and broke records all LCD-displays on the following parameters:
- Best maximum brightness
- The lowest reflection coefficient
- The highest rate of contrast
- Better contrast in daylight
- The accuracy of color saturation and gamut
- The accuracy of image contrast
- The smallest drop in brightness, contrast and color when you change viewing angles
What is the iPhone 6 Plus display is good, but not perfect (record for LCD-displays are not broken), so it is in the resolution (1920 × 1080 against 2560 × 1440) pixels per inch density PPI (401 vs. 538) and the absolute precision color (3.1 JNCD against 2.1 JNCD).
iPhone 6
Display iPhone 6 is almost identical to the display iPhone 6 Plus in features but has a smaller the number of pixels (1.0 MB), which is significantly lower than other popular smartphones (from 2.1. to 3.7 megapixel). And although having a density of 326 ppi at a resolution of 1334 × 750 display it qualifies as a Retina-display, the same display iPhone 6 Plus is, but with a higher resolution picture looks much better. At the same time on the iPhone 6 Plus look better, not only the image with higher resolution than the display, but having a "native" resolution.
But whatever it was, iPhone 6 has a very good display and most users will be happy with him. But surprisingly, Apple has chosen for his "good" rather than "best". Perhaps this was done intentionally to differentiate in this way two of its products, or possibly to increase profits... with Full HD display of 1920 × 1080 iPhone 6 would have been a real king.
Compare LCD-displays iPhone 6 and iPhone 5 Plus, with OLED-display Samsung Galaxy S5 and Note 4
LCD and OLED - the two advanced technologies of mobile displays. They differ significantly from each other, but each of them has their unique advantages.
At this point the display iPhone 6 Plus is the best LCD-display, and displays Galaxy S5 and Galaxy Note 4 - the best OLED-displays. iPhone 6 c 4.7-inch display with a resolution of 1334 × 750 pixels and a density of 326 ppi is closest to the Galaxy S5 with 5.2-inch display 1920 × 1080 pixel density of 432 ppi. A iPhone 6 Plus display 1920 × 1080 pixel density 401 ppi, Galaxy Note 4 corresponds to the 5.7-inch display 2560 × 1440 pixel density of 518 ppi.
