CRT and LCD Monitors

INTRODUCTION:
The CRT monitor has been the essential display device for desktop computers since they are earliest in 1981s. As the new century approaches, that is breach to change. The quality and performance of large flat-panel displays has improved appreciably, and rates have reduced. The LCD monitor is now the ideal
option for some desktop software programs and website.

Each technology (CRT vs. LCD) has advantages and disadvantages; neither is ideal for all situations. The primary advantages for the CRT are its lower cost,
somewhat better overall image quality, reliability, and ease of set up. The LCD is much thinner and lighter, uses less electricity, and is much more versatile with respect to placement and viewing options. Each of these considerations and
others are discussed below.

TECHNICAL FEATURES
LCD monitors are a lot thinner and much lighter than CRT monitors.
The depth of a LCD monitor is typically 3 - 4 inch.
The depth for an equivalent CRT monitor usually exceeds 17 inch, and its weight exceed 45 lbs. This makes moving and positioning very hard. In distinguish the weight of a large LCD monitor usually does not go beyond 25lbs. In addition, some LCD monitors can be mounted on a wall.

QUALITY OF SCREEN
Users will not notice any significant difference between the quality of images displayed on high quality CRTs and LCDs when using business software applications (such as Ms-Office, Open Office etc). The CRT, however, is capable of better color rendering (usually noticeable when displaying photographic images) and provides the user with more control over the excellent look of color images in general. In the same way, video generally will look better on a CRT.

Image quality for an LCD is optimized for only one resolution — the “native resolution”. The native resolution for LCD monitors is currently 1024 x 768.
A few monitors have higher native resolutions such as 1280 x 1024. If an user decides to use a lower resolution (i.e., a resolution that is lower than the native resolution), then image quality will be noticeably poorer. In contrast, the CRT works well at several resolutions.

Images displayed on an LCD at its native resolution often appear to be sharper than the same images displayed on a comparable CRT. This is due to:

• The LCD’s are with higher contrast.
• The 1-to-1 correspondence between pixels in imaging elements.

CONCLUSION
Although a website is designed with excellent image quality and flash animations, we need a quality PC monitor (either LCD or CRT) to display the actual details without any compromise. Website Quality cannot be rated with its clarity which is displayed on a below average monitor.
