Display Technology

Differences between Display Technologies

The choice of display technology can significantly impact the image quality in a computer system. The two main types of display technologies are liquid crystal display (LCD) and organic light-emitting diode (OLED). LCDs are commonly used in desktop monitors and laptops, while OLEDs are used in high-end televisions and smartphones.

LCDs

LCDs are based on the use of liquid crystals to control the amount of light passing through the display. LCDs have a backlight that shines through a matrix of pixels, with each pixel containing liquid crystals that can be rotated to block or allow light to pass through. This creates the image that is displayed on the screen.

One advantage of LCDs is that they are relatively inexpensive to produce, making them widely available and affordable. However, LCDs are limited in their color accuracy and can suffer from a phenomenon known as “ghosting,” where trailing images appear behind moving objects.

OLEDs

OLEDs use organic materials to produce light, eliminating the need for a backlight. Each pixel produces its own light, allowing for greater contrast and color accuracy. OLEDs also suffer from less “ghosting” than LCDs, resulting in smoother motion in moving images.

However, OLEDs are more expensive to produce than LCDs, and they are more susceptible to burn-in, a phenomenon where static images remain on the screen for an extended period and cause permanent damage to the pixels.
