The term display in computing is related to the idea of making visible certain data that are useful to the user (in English, display means to show, to make visible). A screen is the space where that information is available, a space that in Spanish could be understood as a "viewer" since it is the visual portion of the elements, namely. There are many types of displays in computer devices, but undoubtedly some of them are more known and popular, for example, those that have calculators, digital clocks or business cash registers.
Display devices are very varied and can have different objectives. In a certain sense, this concept can be very broad and not very specific, so it is important to begin to define its characteristics a little more. Display will always refer to the visual and external part of a device through which the data that is useful to the user is presented. This presentation can be visual (in most cases), but there are also auditory and tactile displays depending on the device in question. Items such as printers, projectors, and plotters are other common examples of devices that have display devices.
Although in their first moments the display devices were very primitive in terms of design and communication possibilities, today there are great advances that make the information arranged on the screen or display device very sophisticated and in some cases appear up to three-dimensional. Many times, however, the display devices have errors or failures that have to do with access to energy and that have as a consequence the null disposition of the information or the disposition of it in faint colors. When talking about display in the possibility of a program instead of a device, in general, the options for color, size, style and shapes are much more varied.
