Plasma panels and LCD may be similar, but the flat screen and thin is where the similarities end. There are a number of significant differences between the two.
Allow us to understand the meaning of Plasma Televisions and LCD, in order to better understand the differences between them.
Liquid Crystal Display Television (LCD TV).
LCD TV uses LCD technology for its visual output. Liquid Crystal Display or LCD is a thin, flat device consisting of a number of colored pixels or monochrome put infront of a light source or reflector. LCD color of each individual pixel is divided into three cells or subpixels which are colored red, green and blue. Each cell or subpixel can be controlled independently to yield thousands or millions of possible colors for each pixel. LCD TVs can make for excellent TV viewing of High Definition.
LCD TVs – The Good
1. Excellent color reproduction – LCDs can million color screen accuracy.
2. Multi-functional TVs – LCD have a multitude of connectivity options. They typically include inputs for composite video, S-video, High Definition Multimedia Interface (HDMI) and PC In.
3. No Burn In – With LCDs there is no problem In. Burn Some TVs that rely on phosphors such as Plasmas and CRTs can experience Burn In where ghost images are permanently etched onto the screen.
4. Inherently Progressive – LCDs use millions of tiny transistors that can be controlled individually by the "brains" inside the display. Thus LCDs can easily handle progressive-scan sources.
5. High Resolution – LCDs can display high-definition content with a resolution of 1366×768. The highest resolution achieved in a LCD is 1920×1080. 1080p is also called Full High Definition whereas 720p is called High Definition.
LCD TVs – The Bad
1. Expensive TVs – LCD are great, but they are not cheap. TVs LCD cost more per inch plasmas.
2. Reproduction black poor – LCD TVs tend to produce grays, not black.
3. Limited Angle – LCDs viewing angle are typically poor. However, there has been a drastic improvement on this front with the latest LCDs achieve a wide viewing angle of 178 degrees.
4. Slow Response Time – LCDs have response times longer than Plasmas.For example, when you move the mouse very fast on an LCD, multiple cursors times can be seen. This is also known as Ghosting Effect. But this problem seems to have been addressed with the latest LCD TVs with response times as low as 8ms.
5. Low Contrast Ratio – Contrast Ratio is the relationship between the intensity of the brightest bright to the darkest dark. LCDs have lower contrast compared Indices Plasmas.
PLASMA TELEVISION
A plasma screen contains literally millions of gas-filled cells (each one acting as a single image pixel) trapped between two pieces of glass. A grid zaps these cells and causes the gases to ionize (and ionized gas is plasma – hence the name). The ionized gases, in turn, causes a phosphor coating layer of the spectator side of the glass to illuminate. Plasma TVs combine a thin, compact chassis with a truly large size screen. Despite its compact dimensions Plasmas are available in 42 +, 50 + and even 60 + inches.
Plasma TVs – The Good
1. Excellent Brightness – Plasma TVs do not rely on a light bulb shining or reflecting off of something (like an LCD or DLP system does). Plasma brightness is even better than CRT, in a way, because the image is uniformly bright across the entire screen.
2. High Resolution – The best plasma TVs have such high resolutions (and images as good) they look life like.
3. Progressive in nature – all pixels on the screen of light simultaneously. You can have progressive HDTV sources (such as 720p) and from non-HDTV (such as progressive-scan DVD players) displayed to advantage of a plasma HDTV.
4. Wide Angle – Plasmas have a wider viewing angle compared to LCDs. Displays plasma have a good image, even when you're sitting "off axis" (not perpendicular to the surface of the screen). This is a benefit great for smaller rooms, where viewers may sit relatively far to the sides of the screen, wider angle.
Plasma TVs – The Bad
1. Burn-In – Plasmas rely on phosphorus to view video. This can cause Burn-In where ghost images are permanently etched onto the screen.
2. System Short Durability – Another phenomenon of any phosphor-based display is that eventually the phosphors "wear" or lose its luster. This is subtle and slow process, but inevitably happens.
3. Less-than-perfect color reproduction – Although plasma displays can produce a stunning range of colors, a lot of games have the unfortunate tendency to make red colors are more orange than true red.
4. Poor reproduction of black – Plasma TVs below the sphere of reproduction of images in black. Most plasmas work slightly better than LCD TVs at black reproduction, but short of CRTs and some projection systems.
Other factors such as price, weight, power consumption, high-altitude performance and transportation are other considerations that apply to a person to person basis. So I will just briefly state the total difference in these areas.
Prices: Plasma TVs are still significantly less expensive than LCD in sizes over 32 ".
Weight: LCD TVs are considerably lighter and thus easier to assemble and install. So About the Author:
