The abbreviation " VPN " has slowly become established among average Internet users, which is certainly good, but the problem is that people have started to see VPN as the ultimate solution to all problems.

Differences between AMOLED, LCD, Infinity Display, and Retina display
You've probably heard many times about AMOLED, LCD, TFT, and OLED screens on mobile phones, TVs, and tablets, but you don't know the difference between them? Below I will try to clarify the difference between LCD and AMOLED screens in the phone.
When buying a new phone, you usually look at how much RAM there is, how much processing power, how many inches the screen has, what system, and of course, how much it costs. In all these features, there is also detail about the screen. All these abbreviations can confuse you, so you are in a dilemma as to which screen is better.
Well, let's see what are the advantages and disadvantages of AMOLED and LCD screens.
LCD (Liquid Crystal Display)
These screens achieve the most realistic image, but unlike AMOLED and OLED screens, they do not have as widespread color contrast. They also require several layers of glass and backlighting, which also affects battery consumption.
Immediately there are TFT and IPS screens whose features are integrated into LCD screens. TFT (Thin Film Transistor) supports the efficiency of LCD screens by reducing the number of electrodes per pixel.
In addition to TFT, we also have IPS (In-Plane Switching), which improves the LCD screen with much wider viewing angles. LCD is used on almost all monitors, including TVs, and of course on phones.
Some of the more famous models that use LCD screens: are the iPhone 4 / 4s, iPad, and HTC One X.
AMOLED (Active Matrix Organic Light Emitting Diode)
AMOLED screens consist of a thin layer of organic polymers that ignite when electricity is added. These screens are much thinner and do not require backlighting, as is the case with LCDs, so it consumes less electricity. Energy. What are the benefits of turning off the backlight? Well AMOLED screens produce black much better because the pixels of the AMOLED panel go out and thus consume much fewer batteries.
However, these screens also have a drawback - the "pentile" display. What it is? Instead of the screen being arranged so that there are only red, blue, and green pixels (RGB), there are two green subpixels on AMOLED screens instead of one green one. In the image on the left, you will notice that the green pixels are different from the blue and red ones.
The good side of this pixel layout is that the screen has fewer pixels to power while the screen is still normally lit. And the downside, guess what, is that the screen looks like it has fewer pixels, ie it has a lower resolution.
Interesting: Samsung solved this problem by introducing AMOLED Plus technology, which does not use pentyl pixel distribution.
Some of the more famous models that use AMOLED screens: are Samsung Galaxy S series devices, Nokia Lumia 900/920/820, HTC One S
