CRT – Cathode Ray Tube :
A cathode-ray tube (CRT) is a vacuum tube that uses an electron beam to create images on a phosphorous screen. CRTs were a key component of display technology in the late 20th century and were commonly used in televisions and computer monitors.
Advantages of CRTs:
- Superior color accuracy: CRTs generally offer better color depth and contrast ratios compared to older LCDs, providing a more vibrant and accurate image.
- Fast response time:Due to the nature of the electron beam, CRTs have virtually no motion blur, making them ideal for displaying fast-moving content like action movies.
- High native resolution:CRTs can display high resolutions with sharp details when properly calibrated.
- Good viewing angles:CRTs have wide viewing angles, meaning the image quality remains consistent from most viewing positions.
Disadvantages of CRTs:
- Bulk and weight:CRTs are significantly heavier and bulkier than modern flat-panel displays, making them less portable and taking up more space.
- High power consumption:CRTs use considerably more electricity than newer display technologies.
- Screen flicker:The constant scanning of the electron beam can cause noticeable flicker, which can lead to eye strain for some users.
- Moiré patterns:When displaying certain patterns, CRTs can produce visible interference patterns called Moiré effects.
- Limited size:Large CRT displays were difficult to manufacture and expensive, limiting screen size options.
