Most of the gadgets for entertainmentor devices that we use has a screen as the main means of interaction. Televisions, laptops, computers, ereaders, tablets, smartphones. But what makes the screen of these devices have more quality? Is the resolution? Is the size of the screen? Especially when we talk about tablets and smartphones, size or screen resolution that are most important to you?
Screen Size of Smartphone and Tablet
The size of the screen of a smartphone or tablet is the measure of the diagonal of the screen, that is, from the bottom up to the top corner opposite. This measurement is given in inches.
In that influences the purchase of a smartphone or tablet: the larger the screen, the better it is for viewing images and videos. Just remember a movie compared to the TV in your house. Only that the quality of the image is also important, which leads to the comparison of a mobile phone with a poor screen with a cell phone top of the line. But this comparison we will do further below.
The Proportion of the Screen to the Body of the Smartphone or Tablet
A very important information in addition to the size of the screen is the aspect ratio that the screen occupies space in the body of the smartphone. This information is given in percentages. The higher the percentage, the larger the space that the screen of the device occupies, and the smaller the space that the speakers, physical buttons, borders, and other design details occupy.
On what this influences in the purchase of a smartphone or tablet: the larger the proportion that the smartphone screen is, the better. Only with a catch: if the screen occupy the entire space of the front, you may be left with less space to hold on to, which can disrupt to hold the smartphone or tablet in certain positions, and view images at the same time.
Resolution Smartphones and Tablets
The resolution of a smartphone or tablet is a value that defines the amount of pixels that form the images on the screen. The pixel is the smallest unit of image that can be displayed on a screen, briefly. The resolution is given in a measure of lines of vertical pixels and horizontal.
On what this influences in the purchase of a smartphone or tablet: with more pixels are used to form an image, the more detail that image will have, because more “small pieces” were used to form the image. It is important to combine this criterion with the density of pixels per inch. This is because you may have a small screen with few pixels, but very vivid images, and a large screen with lots of pixels and low sharpness.
Pixel Density for Smartphones and Tablets
The pixel density is measure is PPI (pixels per inch), and describes the sharpness and clarity with which the image is displayed on the screen of the smartphone or tablet. Is the relationship between the screen resolution and the size of the screen. The higher the density of pixels per inch, the sharper the image.
On what this influences in the purchase of a smartphone or tablet: at the time you choose a gadget by the size of the screen, do not look at the resolution, look to the density of the pixels. If it is a high number, it is a good sign, that the smartphone or tablet will produce good images.
The Technology Used to Fabricate the Screen
The companies use different technologies to manufacture their screens. LED, OLED, LCD, Retina, etc. These technologies influence, essentially 3 criteria: contrast (difference between black and white), brightness, and vividness of the colors.
On what this influences in the purchase of a smartphone or tablet: there are people who like the most vivid colours, others prefer screens that shine more. Here goes a lot of personal taste.
Therefore, in choosing a smartphone or tablet with a good screen, it is of great importance to combine these criteria to make a sensible choice and that works for you. Better to take time to read these criteria than to regret after the purchase, isn’t it?
