TFT IPS- High quality liquid crystal matrix. Has wide viewing angles, one of the best indicators of color and contrast quality among all that are used in the production of displays for portable equipment.
Super AMOLED- if a conventional AMOLED screen uses several layers, between which there is an air gap, then in Super AMOLED there is only one such touch layer without air gaps. This allows you to achieve a brighter screen for the same power consumption.
Super AMOLED HD- differs from Super AMOLED in high resolution, thanks to which it is possible to achieve a size of 1280x720 pixels on the screen of a mobile phone.
Super AMOLED plus- This is a new generation of Super AMOLED displays, which differs from the previous one by using more subpixels in a conventional RGB matrix. The new displays are 18% thinner and brighter than the older PenTile technology.
AMOLED- an improved version of OLED technology. The main advantages of the technology are significantly reduced power consumption, the ability to display a wider color gamut, smaller thickness and the ability of the display to bend slightly without the risk of breaking.
Retina-display with high pixel density, designed specifically for Apple technology. The pixel density on Retina displays is such that individual pixels are invisible to the eye at a normal distance from the screen. This provides the highest picture detail and dramatically improves the overall viewing experience.
Super Retina HD- the display is made using OLED technology. The pixel density is 458 PPI, the contrast ratio reaches 1,000,000: 1. The display has a wide color gamut and unrivaled color accuracy. Pixels in the corners of the display are anti-aliased at the sub-pixel level, so the edges stay flat and look flat. 50% thicker Super Retina HD gain layer. It will be harder to break the screen.
Super LCD is the next generation of LCD technology and offers improved performance over earlier LCD displays. The screens have not only wide viewing angles and better color reproduction, but also lower power consumption.
TFT- A common type of liquid crystal displays. The active matrix, controlled by TFTs, significantly improves display performance, as well as image contrast and clarity.
OLED- organic electroluminescent display. Consists of a special thin-film polymer that emits light under the action of an electric field. This type of display has a large margin of brightness and consumes very little power.
Smartphone Samsung Galaxy J2 was developed primarily for countries with emerging economies. After all, it was not for nothing that the South Korean giant chose India for the first presentation of the novelty - a country with a developing economy and potential buyers, numbering over a billion.
What's new?
With what Samsung Galaxy J2 going to surprise us?
First of all, at an affordable price. This budget smartphone will be quite affordable for residents of low-income countries: us, Indians, Chinese, Brazilians, etc. To buy it, you do not need to get into loans, and then deny yourself the essentials. And if we take into account its functional filling and high performance, then Samsung Galaxy J 2 may become the most massive model in the "galactic" family of the South Korean manufacturer.
Even in this budget novelty, Samsung engineers were able to implement some very interesting and useful innovations.
Since the installation of high-performance hardware in a smartphone would inevitably lead to an increase in its selling price, it was decided to increase productivity through software solutions.
So, in this gadget, the technology for compressing data transmitted over the wireless Internet, borrowed from Opera Max, was implemented. Thanks to her, it was possible to achieve a 50% increase in the speed of downloading video files. The speed of working with social networks increased by 40% and by 30% when visiting regular Internet sites.
Again, this technology is designed to work in countries with poor LTE coverage. And this is our country, and still the same India.
Specifications
Otherwise Samsung Galaxy J2 has a fairly standard set of characteristics.
AMOLED-screen with a resolution of 960x540 pp together with a 4-core 1.3 GB Exynos 3475 processor provide ample opportunities for communication, entertainment and work. Is that 1 GB of "RAM" will not allow you to enjoy modern resource-intensive games. Even at minimal settings, they will clearly slow down.
If the built-in 8 GB hard drive seems a little to you, then you can install microSD up to 128 GB on your smartphone. The gadget has two cameras - 5MPix main and 2MPix front.
Actually, everything is pretty standard. The same set can be found on smartphones from other manufacturers, but they will cost much more than the Galaxy J2.
