Cathode-ray Tube (CRT) displays have widely been used in televisions and computers for long. The displays have several advantages like wide viewing angles, superior colour resolution and low manufacturing costs. But these displays also suffer from drawbacks like excessive weight and high power & voltage consumption. The configuration of CRTs requires television sets to be virtually as thick as they are wide. Hence the demand for flat panel televisions is increasing day-by-day.

Technologists have developed alternative flat panel display (FPD) technologies to overcome the inherent drawbacks of CRTs. Prominent FPDs include liquid colour display (LCD), plasma display panel (PDP), vacuum fluorescent display (VFD), and electroluminescent display (ELD). A flat panel television display includes a flat panel on which a matrix of cells is formed between two glass substrates. A PCB module drives the panel. There are two types of FPDs – volatile and static.

A LCD provides a richer and higher resolution of colours as compared to the conventional CRT displays. A LCD essentially comprises of two glass substrates that are separated to form a predetermined space into which a layer of liquid crystals is injected. Flat panel televisions are gaining popularity these days as they improve visibility and reduce glare due to reflection of external light.

A FPD is preferred to a conventional spherical panel as it provides higher resolution power. These panels have exceptional colour accuracy and can display up to 16.77 million colours. The FPDs are gaining popularity among the masses as they are light-weight, consume less power and provide relatively sharp resolution.

The flat panel televisions are being preferred by consumers as they reduce image distortion, minimize eye fatigue and provide a wide range of visibility. The FPDs are usually less than 4 inches thick. These displays feature uniform screen brightness which means that they evenly illuminate all pixels across the screen. These displays do not use electronic beams and hence are immune to the effects of magnetic fields. Modern gadgets like laptops, cellular phones and digital cameras come equipped with FPDs. Flat panel televisions have sparked a revolution in home entertainment these days.

The word ‘technology’ is often associated with ideologies about the future and the advancement of society. Although this statement may be true to a limited extent in that technology is about foreseeing the future, technology and advancements in technology are also largely about the present. For example, younger generations are now more skilled in the use of Internet as well as there being an increase in the popularity of computer games. Hence, although there are some negative impacts associated with spending too much time on the Internet and using the Internet as a primary source of research, the present level of encouragement for using technology in schools has helped us as a society prepare for the demands of the future.

Firstly, in an extract from a survey about Internet and schools, it was found that a “recent informal census conducted via voluntary reporting over the Internet estimates the number of teachers and students (individual and classroom accounts) in the U.S. using the Internet, either directly or indirectly, at almost 250,000.” (Parker, 1992, p 22-24). Hence, the increased usage in Internet services has ensured that school-aged children are better adapted to meet the challenges of technology. Although use of the Internet has increased due to both growth in research and uses for entertainment purposes, there are some negative impacts associated with school-age children relying on the Internet as their primary source of research.

Becoming over reliant on the Internet for research due to the level of convenience may result in a lesser range of reference materials used for essays and academic arguments. Also, it creates a bias in terms of the amount of information found. For example, authors in societies that do not have access to the Internet may be marginalized due to the lack of this skill. Also, most Internet sites usually have advertising, and this may cause distractions to the student’s concentration. Therefore, though it can be argued that the Internet has provided access to a larger range of resources and has ensured that communication is a lot more effective, it can become ineffective if people become too reliant on this source of information as their main medium for communication.

The debates involving the Internet are extremely contentious, depending upon the various views and interpretations of different members of society. However, one thing is certain, and that is today’s generation are better able to adapt to the changes and demands of technology. For example, Washington Reuters stated that “nearly one-third of American Internet users surveyed said they go online just for fun rather than to check e-mail, read News, or use a search engine, a sharp increase from a year ago,” (Reuters, 2006, p 1). Hence, this means that as a society, although there has been an increase in software engineering of games and programs, society has kept up in terms of spending time on the computer in order to use these software and programs.

In conclusion, today’s generation has an increased ability to enjoy the benefits of technology and Internet due to the increased usage and reliance on technology. Although the issue is still debatable, as negative effects such as over-reliance on the Internet can affect the functioning of society, benefits also exist, and when used appropriately the Internet can ensure a higher standard of lifestyle.
