A Plasma Television or an LCD TV Set – Which is better

Written by Andrew Ghigo

A Plasma HDTV or a LCD Television – Is this your dilemma? This is a rather difficult and complicated comparison between two technologies that processrepparttar image in a totally different manner.

This article highlightsrepparttar 147541 pros and cons of plasma versus LCD as applicable to a television display. It also presents a set of guidelines to help you determine where either of these two flat panel display technologies fit best.

Plasma or LCD – Which type of display is right for you?

Though both LCD and plasma displays come inrepparttar 147542 form of slim flat panel displays, yet from a technology perspective, these two flat panel displays processrepparttar 147543 image in a totally different manner.

Plasma uses a matrix of tiny gas plasma cells that are charged by precise electrical voltages to emit light and hence to createrepparttar 147544 picture image. Liquid Crystal Displays (LCD) panels - work by trapping a liquid crystal solution between two sheets of polarized glass. When an electric current is passed throughrepparttar 147545 liquid crystals, they changerepparttar 147546 polarization ofrepparttar 147547 light passing through them in response torepparttar 147548 electric voltage – as a result of which, more or less light is able to pass throughrepparttar 147549 polarized glass onrepparttar 147550 face ofrepparttar 147551 display.

It is notrepparttar 147552 scope of this article to go intorepparttar 147553 actual details of how these different display technologies processrepparttar 147554 image – after all, what really matters is not what is going behindrepparttar 147555 screen but rather how these different display technologies perform as a television screen. Atrepparttar 147556 same time, it is worth taking note that it is these same differences that gives each of these display technologies, its strengths and weaknesses, and that therefore renders one more suitable thanrepparttar 147557 other in certain circumstances.

The list below highlightsrepparttar 147558 most important differences between these two flat panel display technologies:

Size: Forrepparttar 147559 time being, collision between plasma television and LCD TV occur inrepparttar 147560 40 to 50 inch screen range. In reality, LCD TVs top out at around 45” – meaning that for bigger screen sizes, a plasma display is your only real option if what you are after is a direct-view TV system. Onrepparttar 147561 other hand, atrepparttar 147562 smaller end of spectrum, namely 15” to 36” TVs, LCD isrepparttar 147563 way to go if what you want is something stylish and slim (at under 4-inches in depth).

Picture Quality, Contrast and Color Saturation: Both plasma andrepparttar 147564 latest TFT-LCD flat panel displays are capable of producing excellent picture quality – with bright, crisp clear images.

However, plasma flat panel displays are more suitable for basic home theater usage than LCD. The gas cell structure within a plasma display is such that there is no light leaking between adjacent cells (or pixels). This renders plasma displays capable of displaying deeper blacks – hence better contrast and detail in television and movie scenes where lots of dark and light content is shown simultaneously.

In comparison,repparttar 147565 nature of LCD technology – where a backlight shines throughrepparttar 147566 LCD layer – means that it is hard for it to achieve true blacks (i.e. true absence of light) as there is always some light leakage from adjacent pixels.

This does not mean that LCD panel s are not suitable as TV screens; today’s LCD TV sets make use of extreme high contrast panels that are capable of displaying deeper blacks, yetrepparttar 147567 latest plasma TV sets still have a slight edge over LCD when it comes to contrast levels.

The situation is somewhat similar when it comes to color saturation. Again, it isrepparttar 147568 different display structure between LCD and plasma that isrepparttar 147569 reason behindrepparttar 147570 difference betweenrepparttar 147571 two technologies in this respect, and though both are capable of handling color in an exceptional manner, yet plasma displays still lead in this respect - producing more accurate and vibrant colors. Viewing-angle:Plasma Television sets – like their CRT TV counterpart - typically have better viewing angles than LCD. The viewing angle represents how far one can sit on either side ofrepparttar 147572 screen away fromrepparttar 147573 center, without experiencing significant deterioration in picture quality – mainly as a result of color shifts and reduced contrast.

Though recent developments in LCD technology means that this is less of an issue with some ofrepparttar 147574 latest LCD TV sets boosting a viewing angle of 160 to 170 degrees vertically and horizontally, yet it is always best to check. The tendency – especially with cheaper sets – is thatrepparttar 147575 deterioration in picture quality is more accentuated with LCD than with plasma displays.

Burn-In: As with all phosphor-based displays, plasma displays are prone to burn-in, or image retention. Screen burn-in occurs when an image is left for too long onrepparttar 147576 screen – resulting in a ghost ofrepparttar 147577 image burned onrepparttar 147578 screen. Surely, keepingrepparttar 147579 brightness and contrast levels down will help reducerepparttar 147580 risk of burn-in.

The ever-changing mobile communications industry is again transforming consumer perception of telephony on-the-move. We’ve come a long way sincerepparttar 80’s "brick like" model that gave usrepparttar 147256 freedom to move away from dingy payphones. In fact, mobile phones today serve a completely new purpose. No longer is it solely aboutrepparttar 147257 need to contact a friend, colleague or family member at any time or place. What reaches out torepparttar 147258 majority of consumers today isrepparttar 147259 uniqueness of a handset; as mobile technology becomes fashion accessory. Constant advancements in technologies ensure we’re spoilt for choice, withrepparttar 147260 capacity to personalise almost every aspect of a mobile phone.

Consumers have been groomed to demand an increasingly high standard of functionality in their mobile phones.
