HD Definitions

Posted on June 28, 2020September 23, 2021 by definitionexplorer

When searching for smartphones, chances are good that you will come across models that have HD + or full HD + screens . But what does this ‘plus’ (or ‘plus’) sign mean? And what is the difference between HD and HD + , for example?

HD

First, it is important that you understand what resolution is. Here at AbbreviationFinder, you can find a full text explaining everything about screen resolution, but follow a “summary summary”.

The screen is divided into tiny points called pixels. These points are organized into rows and columns. The resolution is therefore nothing more than the measurement that indicates how many columns and rows of pixels the display has.

Now, let’s take HD (High Definition) resolution as an example . Also known as 720p , it signals that the screen is, by default, 1280 x 720 pixels. These numbers indicate that the display shows 1280 pixels per line and 720 pixels per column.

Likewise, full HD resolution – also known as FHD or 1080p – indicates that the screen is 1920 x 1080 pixels. Here, therefore, we find 1920 pixels per line and 1080 pixels per column.

Realize that, because it has more pixels than HD panels, a full HD screen can display images in more detail or sharpness.

Ok. But at what point in this story do HD + and full HD + resolutions appear? You may have noticed that, in recent months, the use of the front area of ​​cell phones has increased to allow the screen to take up more space without, however, significantly increasing the physical dimensions of the device.

This is possible thanks to the reduction of the edges of the screens and the implementation of the notorious notch , a notch that houses the front camera and, sometimes, sensors.

The effect of this is to free up more useful space for the screen. If the screen has more space, it can display more pixels. That’s where HD + and full HD + resolutions come from. An HD + screen is nothing more than an HD screen with a few more pixels. The same principle applies to full HD + screens.

You can find a smartphone with an HD + screen that corresponds to 1520 x 720 pixels, for example, or a full HD + display whose resolution represents 2220 x 1080 pixels. The amount of pixels can vary from device to device, but it will always be slightly above the conventional values ​​of HD and full HD resolutions.
