December 8, 2013 at 23:26We consider the display with Assertive Display technology in Nokia Lumia 1520
Our flagship smartphone Nokia Lumia 1520, presented at the Nokia World conference in Abu Dhabi, finally got to Russia. This smartphone has implemented many innovations in both the technical and software parts. Today we decided to talk a little about how the 6-inch screen with adaptive Assertive Display technology, first used in Nokia smartphones, is arranged.
But first, let’s recall what the Nokia Lumia 1520 is. This is our new flagship smartphone (if convenient, a “phablet”) running on Windows Phone 8, moreover with the Nokia Black update (which we will discuss in detail in the future).
Since the Nokia Lumia 1520 was originally conceived as the main flagship device, it received a powerful and most modern filling. For example, the smartphone has a quad-core Qualcomm Snapdragon 800 processor 2.2 GHz, 2 GB of RAM, built-in storage capacity of 32 GB, which can be supplemented by a microSD card slot (supports cards up to 64 GB).
To all this, you can add 7 GB of free SkyDrive storage space in the cloud. This is convenient to use, for example, for teamwork with office documents or for backup photos taken on a 20-megapixel camera.
By the way, the 20-megapixel PureView camera uses the technology that is already used in the 41-megapixel Nokia Lumia 1020 smartphone. The camera is equipped with an optical stabilization system, and in order to get the highest quality video, the smartphone has four highly sensitive microphones.
Nokia Lumia 1520 works both with the usual 3G connection and with LTE networks.
But back to the screen. The Nokia Lumia 1520 has a 6-inch IPS screen with Full HD resolution (1920 x 1080), 16: 9 aspect ratio and a pixel density of 368 pixels / inch.
As with many other models, the Nokia Lumia 1520 display is made using ClearBlack technology. The essence of this technology is that between the Gorilla Glass and the display there are special polarizing and inhibitory layers. They repeatedly change the wave characteristics of the light beam. As a result, when light passes through these layers, they block all glare.
The principle of operation of ClearBlack technology
Taking into account the experience of past models, when developing the first flagship phablet, Nokia engineers did not stop at only one ClearBlack and turned to Apical, which developed Assertive Display technology.
" The Nokia Lumia 920, Lumia 925 and Lumia 1020 have been realized high brightness mode and the algorithm to improve readability in sunlight, which improved the perception of information from the display in the street , - says Jussi Ropo, the Nokia manager of display and touchscreen technologies. - Despite the results, we were still not completely satisfied with the characteristics and knew that they could be improved. After reviewing the various options, we came to the conclusion that the Assertive Display algorithm created by Apical best suits our needs . ”
The essence of Assertive Display technology is that it helps the display to adapt to lighting conditions. Using sophisticated video processing algorithms based on the principles of human vision, the display of a mobile device continuously changes its parameters, providing a stable and high-quality image in any conditions.
Instead of changing the brightness of the entire display according to one set of parameters, the Assertive Display on the Lumia 1520 adjusts the levels of individual pixels to make the screen more readable. If the content on the screen on the right is darker than on the left, the pixels on each side will be stimulated differently to maximize both visibility and quality. The result is a screen that most fully responds to the environment.
Operation of Assertive Display technology on a standard monitor
Assertive Display technology allows you to maintain contrast at 1000: 1 in bright sunlight, while in traditional displays this value is approximately 10: 1. As an example, we can cite this video, immediately noting that it was made by a private user and is not of an advertising nature:
Another positive aspect of this technology is that the displays of devices with Assertive Display support, according to Apical, consume on average 30-50% less energy than traditional displays. This cannot but affect the decrease in battery consumption of the mobile device.
At the end of the post, we would like to ask the habrasociety: what do you think of the Nokia Lumia 1520 display and the device as a whole? Tell us in the comments which features interested you the most, is this format of a mobile device convenient for you, and could you change your current device to the flagship Lumia.
