Most of the entertainment gadgets or devices we use have a screen as the primary means of interaction. Televisions, notebooks, computers, ereaders, tablets, smartphones. But what makes the screen of these devices have more quality? Is it the resolution? Is the screen size? Especially when we talk about tablets and smartphones, size or screen resolution that are more important?
Smartphone and tablet screen size
The screen size of a smartphone or tablet is the measure of the diagonal of the screen, that is, from the bottom corner to the upper, opposite corner. This measurement is given in inches.
As it influences the purchase of a smartphone or tablet: the larger the screen , the better it is to view images and videos. Just remember a movie theater compared to your home TV. Only the image quality is also important, which leads us to compare a poor screen with a top-of-the-line cell phone. But this comparison we will do below.
Screen ratio for your smartphone or tablet body
A very important information beyond the size of the screen is the proportion that the screen takes up space on the body of the smartphone. This information is given in percentage. The higher the percentage, the larger the space the device screen takes up, and the smaller the space that speakers, physical buttons, borders, and other design details occupy.
As it influences the purchase of a smartphone or tablet: the greater the proportion that the screen of the smartphone occupies, the better. Only with a catch: if the screen fills the entire front space, you may have less space to hold, which can be a mess to hold your smartphone or tablet in certain positions and view images at the same time.
Smartphones and tablets resolution
The resolution of a smartphone or tablet is a value that defines the amount of pixels that make up 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 vertical and horizontal pixel lines.
As it influences the purchase of a smartphone or tablet: the more pixels are used to form an image, the more detail that image has, because more “small pieces” were used to form the image. It is important to match this criterion to the density of pixels per inch. That’s because you can have a small screen with few pixels, but very sharp images, and a big screen with many pixels and little sharpness.
Pixel density for smartphones and tablets
Pixel density is measured at PPI (pixels per inch), and describes the sharpness and clarity with which the image is displayed on the screen of your smartphone or tablet. It is the relationship between screen resolution and screen size. The higher the pixel density per inch, the sharper the image.
As it influences the purchase of a smartphone or tablet: when choosing a gadget by the size of the screen, do not look at the resolution, look at the density of pixels. If it’s a high number, it’s a good sign that the smartphone or tablet will produce good images.
Technology used to make the screen
Companies use various technologies to make their screens. LED, OLED, LCD, Retina, etc. These technologies essentially influence 3 criteria: contrast (difference between black and white), brightness, and vividness of colors.
As it influences the purchase of a smartphone or tablet: there are people who like more vivid colors, others prefer screens that shine brighter. Here goes a lot of personal taste.
So when choosing a smartphone or tablet with a good screen, it is very important to combine these criteria to make a wise choice that works for you. Better take the time to read these criteria than to regret it after the purchase, right?
