Abstract- Social, economical, and environmental effects of Liquid Crystal Displays(LCD) which have been using widely in televisions,<br />
computers, mobile phones, cameras, video cameras, bill boards were discussed. The periods before and after introducing of LCDs were compared<br />
in terms of Energy, Information Technology ,Communication Technology, Environment, and Social Life. Advantages of LCDs were explained<br />
depending on development of Nanotechnology in displays. LCDs’latest position was evaluated.<br />
………………………………………………………………………………………………………….<br />
In the begining of 1960s Liquid Crystal Displays (LCDs)<br />
have entered to our life. When we go back to 1970s LCDs<br />
have been observed in calculators and watches[1]. They had<br />
only black and white displays at that time. LCDs helped so<br />
much in daily life comparing with mechanical wristwatch and<br />
abacus in those years depending on that technology. LCDs<br />
important role in social life, starting to development beginning<br />
from primitive technology to Nanotechnology, have been<br />
increasing day by day. At present, LCDs are involved in<br />
human life in different aspects such as communication,<br />
information technologies, entertainment, cultural and artistic<br />
activities.<br />

In view of energy and usage, TV screens made of LCDs<br />
exhibit low energy consumption with respect to televisions<br />
produced by Cathode Ray Tube(CRT). This situation makes<br />
LCDs more advantages to televisions made of CRT. For<br />
instance, televisions made in small size with LCDs can be<br />
used with low voltage (around 10 Vs). So even a couple of<br />
batteries are capable of usage of LCD TV.[2] This case<br />
enables us to use TVs with LCDs in a wide range of places<br />
(without electrical sources) which we can never have this<br />
chance to use TVs with CRT.<br />
In point of information technologies, mobility feature of<br />
LCDs have shown in movable computers such as laptops.<br />
Low energy consumption concept, decrease in size and<br />
increase in mobility have made our life much easier by<br />
computers produced with LCDs such as laptops as mentioned<br />
above than desktop computers.[3] With the help of LCD<br />
technology improving of laptops, today, access to information<br />
and usage of laptops are possible in every single moment of<br />
daily life.<br />
Importance of LCDs in communication technology has<br />
outcome with progressing of mobile phones[4]. Before<br />
introducing mobile technology to our life, regular phones were<br />
playing partially role. Entering with mobile communication to<br />
our life, communication put into effect in every moment of<br />
daily life. Improvement of LCDs technology has been playing<br />
most important role in progressing of mobile phones.<br />
In point of environmental aspects of LCDs we see that:LCD<br />
does not emit that much of radiation compared to television<br />
with CRT. When we compare them regarding emitting<br />
radiation, radiation emitted with sight almost approaches to<br />
zero in LCDs which leads to positive effect on environmental<br />
pollution and human health. All displays with LCD like TV,<br />
computer compared to displays with CRT has been helping us<br />
in terms of environment and human health.[5]<br />
When we consider LCDs in view of social aspect, we can<br />
tell that they occupy important role. Starting from crowded<br />
entertainment places and shopping centers and places where<br />
offical services are served, on deck of ferries, at ports, on<br />
public and private transportations etc., by serving LCDs is an<br />
significant indicator of LCDs that they have played very<br />
effective role in social life. Besides, nanotechnology has<br />
brought a new perspective to advertising sector by introducing<br />
giant size of LCDs resuls in activity and new dimention in<br />
commercial life.<br />
To sum up, replacing TVs with CRT with LCD technology<br />
the world has started a new period considering energy saving,<br />
economy, environment and social communication. It is not<br />
difficult to say from now on that the role and impact of LCDs<br />
in our rotuine life will be more effective as nanothechnology<br />
develops and become a piece of our lives.<br />
