Displays, or digital screens, are visual output devices that present images, videos, and text to users. They range from small screens on smartphones and wearables to large televisions and digital billboards. Key types include Liquid Crystal Displays (LCDs), known for their energy efficiency; Light Emitting Diodes (LEDs), prized for brightness and clarity; and Organic LEDs (OLEDs), offering deep blacks and flexibility for curved screens. E-Ink displays mimic paper and excel in readability under sunlight. Displays serve various purposes: smartphones for personal use, monitors for computing, TVs for entertainment, and digital signage for advertising. Touchscreen displays add interactivity, allowing users to engage directly with the content.
Digital displays began as cathode-ray tubes (CRTs) in early televisions and monitors, bulky and power-hungry. The 70s introduced Liquid Crystal Displays (LCDs), slimmer and more energy-efficient, revolutionizing watches and calculators. By the 2000s, LCDs dominated TVs and computer screens, enhanced by LED backlighting for brighter images. The 2010s saw Organic LEDs (OLEDs) emerge, allowing for thinner screens with richer colors. E-Ink technology surfaced, ideal for e-readers due to its paper-like appearance and low power use. Touchscreens became widespread, first in ATMs and later in almost every handheld device, transforming user interaction.
Imagine walking into a room where the walls themselves are vibrant displays, changing scenery with a tap. Digital displays are heading towards this level of immersion. Foldable screens are just the beginning, soon evolving into stretchable, even rollable displays that can turn everyday surfaces into interactive canvases. Transparent displays, like those glimpsed in sci-fi movies, will blend seamlessly into windows and eyeglasses, providing real-time information without obstruction.
With advancements in holographic technology, 3D visuals could hover mid-air, making video calls and gaming spectacularly lifelike. As displays evolve, they'll become more than just screens; they'll be windows to new realities, enriching culture and connectivity.
Measure a screen size by measuring diagonally from one corner to the opposite diagonal corner. Only include the screen area and do not include dimensions of the screen’s frame or casing. Use a measuring tape or ruler to measure your screen size.
A monitor can be calibrated by using a color calibrator called a colorimeter that is placed on the front of the monitor or it can be done manually by eye. The easiest method to calibrate a monitor is through the computer’s calibration utility that is offered by both Windows and Apple operating systems.
A retina display is marketing term by Apple to describe a screen that has great pixel density. When looking at a screen with retina display you won’t be able to see any individual pixels. A retina display offers more than 300 pixel per inch and has more color saturation.
