SCREENS (computer) | 12 types, characteristics and their operation

We share the differentscreen types that have been developed to date and their characteristics, present in TVs, smartphones, computer monitors and more

INDEX

Screen types

With the passage of time and the development of technology have developed different types of screens, where each one presents certain characteristics that not only improve the image quality for the viewer, but consume less energy, are more resistant, prioritize visual health, among other details.

Gorilla Glass screen

They are a type of screen that has transparent sheets, which are thin and ultra resistant, which is why they are the most suitable to avoid scratches or breakage. The Gorilla Glass screens are widely used in smartphones, particularly high-end ones.

For the elaboration of the material from which Gorilla Glass is made today, it was based on a previous product called Chemcor which was developed in 1962, although it had components and a different formulation.

Amoled screen

It is a kind of screen that is used more than anything on smartphones and mobile devices. It is the acronym for active-matrix organic light-emitting diode and in that sense it is an active matrix that has organic diodes that emit light. For its manufacture, OLED screens were based.

Due to the characteristics of the AMOLED screen it is possible that attention and configuration are directed to a specific pixel, which is why it is possible to reflect on higher, more expensive models and that perhaps consume much more energy.

Amoled screen

OLED screen

OLED screen or organic light emitting diodeIt is a kind of diode that has an electroluminescent layer that is formed by a film with organic components, which are reacted according to an electrical stimulation, so that it is generated and in turn emits light.

Due to their characteristics, OLED screens have several applications, such as monitors, televisions, laptops, an information or warning indicator, etc.

MultiTouch screen

The MultiTouch screen or multi-touch screen it is the way in which the technique that gives interaction between a person and a computer, just like at hardware to which it applies. To understand the operation, it has to do with a touch screen or a touchpad, which is designed to recognize several or multiple points of contact, in addition to software that interprets these interactions.

They are capacitive screens similar to those of modern smart phones that have an array of optical sensors. The most relevant feature is that they obtain the position of different contact points in it simultaneously.

MultiTouch screen

TouchScreen screen

TouchScreen screen or touch screen and in some cases it is called tuch. It is a type of screen that through a direct touch on its surface will allow data entry, receive orders and also show the result of each of those instructions.

Is a peripheral input and also peripheral output of data, in addition to being able to emulate interim data that are erroneous if not touched effectively. It is possible that contacts are made with an optimal pencil or similar.

Led screen

The led screen It is made up of LEDs that are designed to display information, data, videos, images and more, to each of the viewers who are close to that signal.

The LED display is characterized by having light emitting diodes or LEDs. It is a screen composed of pixels through modules or LED panels. With the pixels the texts, characters, images, video and others are formed.

Led screen

LCD screen

LCD screen or liquid crystal display. It is a type of screen that is thin and with a flattened shape, which has a number of pixels in color or perhaps monochrome, which are located just in front of a light source or a reflector.

It should be taken into account that the LCD screens typically have a layer of molecules that line up between two transparent electrodes, as well as two polarization filters, where the transmission axes of both are perpendicular to each other. If the liquid crystal was not between the polarizing filter, the light passing through the first filter will be blocked in the second polarizer.

Plasma screen

Plasma screen or Plasma Display Panel, is a plant screen device that was used in most cases in large televisions. A negative feature that highlights them is that they are screens that emanate excess heat, so it is not pleasant for users who spend many hours before them.

The plasma screen has tiny cells that are located between two glass panels that have a mixture of noble gases. That gas in the cells transforms electrically into plasma, to give a phosphorescent substance that emits light.

Plasma screen

SVGA screen

SVGA screen or Super Video Graphics Array. Actually, it is a term that alludes to a very wide range of visualization standards for computer graphics, where in turn the video cards or the monitors.

In comparison with the VGA screens it was a considerable advance because it could display a resolution of 256 colors and a combination in resolution of 640 x 480 pixels.

VGA screen

Video Graphics Array or VGA screen. It is usually defined as the standard of an analog screen of a computer, with a resolution of 640 x 480 pixels, a 15-pin D-sub connector and because it is an important change at the technological level with respect to the CRT screen.

CRT screen

It is a very old screen, which is typical of the first computers that were massified for desktop use. In principle they were monochromatic to later give way to color, although in a limited way. This was the first screen generation.
