CRT vs. LCD: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on February 13, 2024
CRT (Cathode Ray Tube) uses electron beams to illuminate phosphors; LCD (Liquid Crystal Display) uses liquid crystals and backlighting for image display.

Key Differences

CRT, or Cathode Ray Tube, technology involves firing electron beams at a phosphor-coated screen to produce images. In contrast, LCD, or Liquid Crystal Display, creates images using liquid crystals that align to block or pass light from a backlight.

CRT displays are known for their deep blacks and wide viewing angles but suffer from bulkiness and high energy consumption. LCDs offer a thinner, more energy-efficient alternative, although they can struggle with true black representation and viewing angle consistency.

The weight and size of CRTs are significant due to the vacuum tube technology and large glass screens. LCDs, utilizing thin layers of liquid crystals and light-emitting diodes or fluorescent backlights, are much lighter and slimmer.

In terms of image quality, CRTs excel in color accuracy and response time, making them popular for certain professional applications. LCDs, however, provide higher native resolutions and do not suffer from geometric distortion or flickering issues common in CRTs.

CRT technology is largely obsolete now, replaced by LCD and other modern display technologies in most applications due to their compact size, lower power consumption, and evolving image quality.
