Why iPhone 7 finally gave up OLED screen
Although iPhone 7 and iPhone 7 Plus have
been launched for some time, the current retail price of the iPhone 7 is still
high for most users, and even difficult to buy because of out of stock. But
this also reflected from another side. IPhone 7 series still have some
exquisite and outstanding characteristics that are enough to make other brands
of "flagship phone" dwarfs.
Although the vast majority of the media
experience on iPhone 7 real machine and personal experience on the new machine
are full of praise, but it is undeniable that no mobile phone is perfect. Even for
the latest iPhone 7, there are some "shortcomings". Or said the pace
of improved progress is not enough to make people feel amazing, such as its
screen.
Indeed, the iPhone 7 screen compared to
previous generation iPhone 6s has achieved obvious development. One highlight is
brighter, the screen brightness increased by 25% to 625cd / m2. The second is
more brilliant, the screen color gamut has been the largest expansion To the
DCI-P3, to the film industry's high-definition photography gamut, far better
than other mobile phone NTSC or sRGB color gamut.
However, thinking about the original rumors
that iPhone 7 would use OLED screen (organic light-emitting diode) you will
find that Apple eventually gave up the "evolution" on iPhone 7 screen
materials. Instead Apple chosen to adhere to the LCD (liquid crystal display)
program, just only did some improvements on Backlight module.
For the current mobile phone screen
material, OLED surely has some unique features, such as the advantage of black no
power consumption and derived Active Display black screen fast display. For example,
because no need backlight, the screen can be thin or even to achieve the
surface screen, flexible screen and other special shapes.
However, currently the biggest problem of OLED
lies in its brightness and capacity and its life. The former is easy to understand.
Current best mobile device OLED screen is that piece of Samsung S7 edge and Note7.
In the test by authority hardware Evaluation website AnandTecd, the highest
continuous brightness of OLED screen can only reach 359 nits, while the Apple
iPhone 6S LCD panel in the same test can reach 500 nits of the official
standard with no pressure, the measured number even Up to 582 nits. What does
this mean? For users higher brightness means better image dynamic performance. More
importantly, in the environment of outdoor sun exposure, the brightness level
difference may mean whether you can clearly see the contents on screen.
In addition, limited capacity of OLED
screen is currently also an important factor that restricts Apple's large-scale
screen real-installed. We all know that on electrics consumer market, the main OLED
manufacturer is Samsung, and Samsung's OLED production capacity in addition to
their own, is very large parts of other mobile phone manufacturers with high-priced
package. Apple unable to get enough stable supply capacity, so certainly didn’t
risk. Besides at present for industrial products, the conventional monochrome
LCD and TFT color screen is still the best choice, both its display and life
are much higher than the OLED.
As we all know, Apple's iPhone, iPad and
Macbook have always attached great importance to the accuracy of the screen
color, which is not unrelated with Apple Computer geeks and professional
positioning (although now most of the buyers are not professional users ).
Although Apple did not use OLED on iPhone 7 screen, by strengthening the LCD
technology in brightness, color, color gamut, and gray scale have reached a
professional level, and once again disdain for all other mobile phone manufacturers.
Apple is currently using the technology
which is basically the IPS level, so for this time TN is certainly not used.
AMOLED production capacity is insufficient, and then the remaining choice is only
VA. VA is essentially the opposite of the structure of IPS, the display is also
opposite: low viewing angle, excellent black performance and color quasi. For
large size professional graphics display, this is just a good fit. But For
mobile devices, this can only be too bad. You may still remember the SONY
Xperia Z1 which used VA display, after listing because of its narrow viewing
angle it was widely complained. Although I don’t understand, if just need to
see content of the phone, Why use wide viewing angle. Since this is the
consumer's "public demand", presumably Apple did not dare to take
risks.
Those who read the Steve Jobs biography
should all remember the book has mentioned the anecdotes about leader and
Corning Company, which reveals future may appear all-glass body iPhone. Now all
kinds of information show in 2017 the new iPhone as 10 anniversary
"commemorative edition" will be reborn, using a large number of new
design and technology. By then, in addition to all-glass body, Apple self-researched
and related manufacturers OEM Micro-LED screen is also likely to be officially
available. It's not hard to imagine that this new technology, which goes beyond
the existing LCD and LED, will bring new vibrations to the entire handset
industry, just like the Retina display several years ago.
