Differences between plasma and LCD
Plasma and LCD screens may look similar, but the flat screen and thin profile where the similarities end. There are a number important differences between the two.
Let us understand the significance of plasma and LCD televisions to better understand the differences between them.
LIQUID CRYSTAL DISPLAY TELEVISION (LCD TV).
LCD TV uses LCD technology for visual output. Liquid Crystal Display or LCD is a thin device, flat screen consists of a number of color or monochrome pixels arranged in front of a light source or reflector. In color LCDs each individual pixel is divided into three cells, or subpixels, which are 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 viewing of high definition TV.
LCD TVs – The Good
1. Excellent Color Reproduction – LCD can display millions of colors accurately.
2. Multi-functional – LCD TVs have a plethora of connectivity options. They typically include inputs for video composite, S-video, High Definition Multimedia Interface (HDMI) and PC In.
3. No burn in – With LCDs there is no burn in problem. Some TVs that rely on matches such as plasmas and CRTs can experience Burn In where ghost images permanently etched on the screen.
4. Inherently Progressive – LCDs use millions of tiny transistors that can be controlled individually by the "brains" inside the screen. So LCDs can easily handle progressive-scan sources.
5. High resolution – LCD can display high definition content with resolutions of 1366×768. The highest resolution achieved in a LCD is 1920×1080. 1080p is also called Full High Definition 720p, as it is called high definition.
LCD TV – El Malo
1. Caro – Televisions LCDs are great, but they are not cheap. LCD TVs cost more per inch plasmas.
2. The reproduction of the black poor – tend to produce LCD TVs gray, not black.
3. Limited Viewing Angle – LCDs have typically poor viewing angles. Lately however, there has been a dramatic improvement LCD on this front to achieve a wide viewing angle of 178 degrees.
4. Slow Response Time – LCDs have longer response that Plasmas.For example, when moving the mouse too fast on an LCD, multiple cursors can sometimes be seen. This is also known as ghosting. But this problem seems to have been treated with the latest LCD TVs with response times as low as 8 ms.
5. Low contrast ratio – Contrast ratio is the relationship between luminosity of the brightest to the darkest. Have comparatively lower LCD contrast ratio of plasmas.
PLASMA TELEVISION
A screen Plasma contains literally millions of gas-filled cells (each acting as a single image pixel) trapped between two pieces of glass. A zapping grid these cells and causes the gases to ionize (and ionized gas is plasma – hence the name). The ionized gases, in turn, create a layer of phosphorus in the side layer the sight glass to light up. Plasma TVs combine a thin, compact chassis with a screen size really great. Despite its compact dimensions are plasmas available in 42 +, 50 + 60 + and even inch sizes.
Plasma TV – the good
1. Brightness – Plasma TVs are not based on a light bulb that shines through or reflecting off of something (like an LCD or DLP system does). Plasma brightness is even better than CRT in some way because the image is uniformly bright across the screen.
2. High Resolution – Plasma TVs have better resolutions as high (and so smooth images) that are life like.
3. Progress in nature – all the pixels in the light of the screen simultaneously. You can have progressive HDTV sources (eg, 720p) and HDTV sources (eg, scanning Progressive DVD players) displayed to full advantage on a plasma HDTV.
4. Wide Viewing Angle – Plasmas have a viewing angle compared with LCDs. Plasma screens have a good image, even when you're sitting "off axis" (not perpendicular to the surface of the screen). This is a great benefit to the small rooms, where viewers may sit relatively far side of the screen, at wider angles.
Televisions Plasma – The Bad
1. Burn-In – Plasmas rely on phosphor to display video. This can cause burns from the ghost images when they are permanently etched on the screen.
2. Short shelf life – Another phenomenon of any visualization system based on phosphorus is that eventually matches "Wear" or lose its luster. This is a subtle and slow process, but it inevitably happens.
3. Less-than-perfect color reproduction – Although the screens plasma can produce an extraordinary variety of colors, a lot of sets have the unfortunate tendency to make red colors look more orange than true red.
4. Poor reproduction of black – Plasma TVs fall short in the field of black image reproduction. Most plasmas do the work a little better than LCD TVs at black reproduction, but fail to CRTs and some projection systems.
Other factors such as price, weight, energy consumption, high performance and transportation are other considerations that apply to a person to person basis. So just briefly the general differences in these areas.
Prices: Plasma TVs are significantly less expensive than LCD in sizes over 32 ".
Weight: TVs LCDs are considerably lighter and easier as assembly and installation. So
