Abstract This paper examines how, like television sets, computer monitors also display images on a screen, but they have quite different functions. It looks at how the monitor is a very important part of a computer and how choosing a monitor for a computer is a very crucial decision to be made. It discusses how the power consumption of the monitor can be reduced by as much as 90% by choosing a proper monitor with built-in power management features that are user-friendly. It also provides an insight into two of the most common types of monitors in use today, the CRT (Cathode Ray Tube) monitors and LCD (Liquid Crystal Display) monitors.
From the Paper "CRT types of monitors are the ones that we have been in use for a number of years. Cathode Ray Tubes are over 75 years old and are even older than vacuum tubes, which were used, for amplification of signals. CRTs were first used for radar during the Second World War. It is being predicted for a long time that these tubes consume too much energy and are not likely to be used in future devices or products for more than another 10 years. These expert predictions have been consistently wrong over the past decades, but now the full motion video seems to be on its wall. These are being replaced by flat panel displays, which have been dreamt of by the scientists for the last 30 years."
Abstract The paper discusses dry-cell batteries which were invented as an alternative to higher leaking, long lasting batteries. Today's advanced electronics are demanding more battery power and it is not unusual for a highly developed electronic item to go through two or three sets of batteries in a day. The paper shows that as technology advances, the stronger the battery demand and this brought about the invention of the dry-cell battery. The purpose of this technical research is to define dry cell batteries, their kinetic make-up, and how are they recycled.
From the Paper "Recycling batteries saves the environment and ensures proper disposal. There are many programs which assist in helping individuals learns how to recycle batteries. There is one program called "Charge Up To Recycle" which educates people on the recycling process, and the companies that recycle batteries. The objective of this program is to make everyone aware of the available services and encourage them to participate in recycling of the batteries. There are some battery recycle facilities that charge a small fee for used up batteries, but most of these facilities will take the batteries free of charge. The purpose of the battery manufacturers is to get everyone involved in recycling old batteries. Recycling batteries can be very beneficial to the air, eliminating lots of air pollution."
Abstract This five-page paper is about LCD monitors. It firstly says what they are, and then it goes on to say how they are different from conventional Cathode Ray Tube monitors. Then it touches on the advantages and disadvantages compared to conventional monitors. In the end it goes on and discusses new technologies.
