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.
