Computer Display

• 23'', or 23 inches, is the diagonal size of the display in inches. It indicates how large the computer screen is.

• 16:10 is the ratio of the screen's width to the screen's height, called the aspect ratio. It tells how large the width is with respect to the height. [Challenge question: If you know both the diagonal size and the aspect ratio, what famous math theorem will you use to find the sizes of the width and height in inches? Hint: there are 90 degrees between two adjacent edges of the screen.]
• 3840 x 2160 is the pixel resolution. Bigger numbers mean more pixels built into the display, a higher resolution, and, therefore, much sharper quality of the displayed images.
• LCD, LED, and Curved are 3 monitor types, representing the technologies used to build the display. LCD ("liquid crystal display") uses a liquid crystal solution between two layers of polarizing material. When an electric current is passed through the liquid, it either blocks or allows light to pass through, which forms images. LED ("light emitting diode") is an LCD using LED backlights instead of fluorescent lights. A curved display uses LCD or LED but has an inward-curved screen. LCDs are more affordable, and LEDs are thinner, brighter, and more energy-efficient than traditional LCDs, with better contrast ratios and more vivid colors.
