When it comes to acquiring new devices, we cannot conceive of its features as something isolated and look for a leading terminal in a single feature but leave much to be desired in the rest of them, but we must look for the most balanced models possible in all aspects and also have a positive impact on the final price. Manufacturers are aware of this fact and, although they sometimes make mistakes, they try to satisfy the needs of users in the best possible way, launching media that try to offer millions of consumers the best possible experience.

When we have talked about the specifications in the matter of image, we have given a series of recommendations in which a good resolution was combined with an ideal screen size with which we could make the most of our tablets and smartphones especially when it comes to leisure and consumption audiovisual content. However, there are other aspects such as those related to color and image formation They also have their impact. Below we present the main types of panels that we can find in the supports currently marketed and we tell you what their main strengths and weaknesses are.

1. LCD

This type of panels has been the most popular for several years on both tablets and smartphones. These are screens of liquid crystal whose main strength is its low manufacturing cost. However, it has important limitations in aspects such as resolution, which can sometimes be very low and not offer a minimum sharpness, and a excessive consumption of battery as well as a greater thickness. These limitations have tried to solve itself by developing two additional LCD technologies, the first, TFT, is aimed at larger media such as computer monitors and optimize consumption of energy when using them. The most current and also extended to portable devices is the IPS, characterized by saving even more resources and offering a higher color quality and realistic than its predecessors.

The great advance of this system is the fact that each pixel can issue light individually. Distributed in groups that emit red, blue and green tones, as a whole they are able to create the entire color gamut. Some of its strengths include the higher brightness of the panels and the possibility of creating them with different shapes, even curved, which moves away from the rigidity of the LCD. Your biggest limitation is given by him production cost, which has a direct impact on the final price of the devices that incorporate it and that attracts both firms when creating new models with this screen and users when acquiring them.

3. Retina

Developed by IBM in the 90s and present in most of the devices of Manzana. Its base is in offering a resolution very high and make it equal or greater from which you can capture the human eye when focusing objects at short and medium distance. Its most important drawbacks are two: The high price of manufacturing panels that do not end up offering excessively high image quality and the fact that the eye, due to its composition and structure, is unable to appreciate superior image quality.

Equipped primarily in terminals Samsung, is a leap forward of technology OLED. In order to increase the image quality to its maximum limit, try break down each pixel in other smaller elements and as in OLED, treat them individually, so that a much wider color palette is formed that can reach 16 million tones On the other hand, it offers a higher brightness of the screen and better highlights the contents and at the same time, saves battery and has a lower expenditure of resources since when the screen turns off, it stops supplying power to each pixel. This technology has evolved to the Super AMOLED, which further fragments each point and improves the sharpness obtained. Among its main drawbacks, we find once again the price, and the fact that the human eye needs to be subjected for a period of time to the high image quality offered by these products in order to adapt.
