Identifying Differences Between TED Hose & Compression Stockings

More and more individuals require either a TED Hose or Compression Stockings due to a variety of popular conditions, Diabetes, poor circulation, excess fluids (water retention) and D.V.T (Deep Vein Thrombosis) which is a blood clot in a deep vein, usually in the leg(s), both a TED Hose and a Compression Stocking will alleviate conditions related to the mentioned conditions. Medical professionals often identify both TED hose and compression stockings by the same title, TED hose, but there is a significant difference between them.

TED hose is frequently given to patients when they are in the hospital or medical facility. TED hose are designed for individuals that are non ambulatory, or lying down 95% of the time. The compression starts in the calf and decreases as it goes up the leg. The reason the compression starts in the calf, when we are lying down fluid tends to travel no further than our mid leg. The stockings will help push additional fluid from that position up through the lymphatic system, then out the body. TED hose are usually white in color and available as a thigh high or knee high style. Normal compression generally lasts two weeks; this is why when you’re in a hospital or medical facility they consistently change your TED hose. In contrast to TED hose, compression stockings offer an array of styles and color choices; therefore they are both fashionable and comfortable. Compression stocking styles vary from knee high, thigh high, pantyhose, and maternity pantyhose.

Compression stockings are available in a sheer material, trouser sock, and athletic sock styles. Compression begins in the ankle and decreases as it goes up the leg. Individuals who have the ability to sit, stand, and walk have gravity working against them, gravity pulls away additional fluid from the upper and mid leg to the ankle and foot, thus eliminating swelling problems among others. When wearing a medical grade compression stocking, the compression begins at the forefoot and decrease as it goes up the leg pushing any extra fluid up and out of the area. Normal compression lasts six months giving the user more time before having to obtain replacement(s).

Certain circumstances allow a person to gain assistance with the purchase of compression stockings. Individuals whom are being treated for an open wound and/or ulcer have the opportunity to gain coverage from insurance as long as all necessary documentation has been made available to the provider. Typically, this consists of a prescription from your physician as well as a CMN (Certificate of Medical Necessity) completed by a wound care specialist. Most insurance differ in regards to coverage and reimbursement, be sure to check with both your doctor and your insurance to see if you are eligible to receive these products.

What’s the Difference Between Plasma TVs and LCD TVs?

Plasma and LCD TVs are the latest trend in home entertainment. Both offer unrivalled picture quality and resolution, while doing away with the bulkiness of the older rear-projection technologies. But with all of the hype surrounding these two types of televisions, what is the difference between them? Although they look- and are virtually priced- the same, they are not.

There differences are found in the way in which they display their pictures. Plasma TV technology is made up of hundreds of thousands of little pixels, each capable of displaying red, green, and blue colors. A plasma monitor often consists of two panels, which are filled with an inert gas, such as xenon or neon. When the pixels are excited by pulses of electricity, the gas becomes liquid, thus generating light. This light in turn then illuminates the pixels, causing them to display the appropriate color to form a picture.

LCD panels function in a very similar manner. A panel of thin-film-transmitters, or TFT, sends electricity to cells filled with liquid crystal. When the cells are struck by the electricity, the liquid crystals allow light to filter through. Unlike the pixels found in plasma TVs, LCD monitors create color by blocking out the appropriate wavelengths from white light.

So which is better? The answer to this question depends upon what you plan to use TV for. Do you just want to use it to watch movies and television? If so, then a plasma TV might be best, because they are capable of a higher better color saturation and contrast than their LCD counterparts and for displaying moving images. If you plan in spending a lot of time showing digital photography or plan on using the monitor with your computer, then a LCD display might be better suited to these purposes.

Both plasma and LCD technologies each have their advantages and disadvantages and your decision should ultimately be based on your monitor’s application.

What Is The Difference Between LCD And LED Televisions?

Looking for a new television can be a confusing experience. With all of the latest TV technologies, it can be difficult choosing the best TV for you. Two types of televisions that people will often compare are the LCD TV and LED TV. The following is a brief guide on the difference between an LCD and LED television to help you make your television selection.

Technically speaking, LCD TVs and LED TVs are both LCD TVs. The screen on both types of TVs is a liquid crystal display. The LCD television is a flat-panel television. With a LCD display, there are 2 layers of polarized glass which are joined together. The liquid crystals are contained in one of the layers. The liquid crystals pass or block the light to display the television image. The crystals do not produce their own light. The light comes from fluorescent lamps that are located at the back of the screen. Arranged in a grid are millions of shutters that open and close to release light and capture light that is not needed to produce images. Each shutter is paired with a colored filter which produces a sub-pixel. The sub-pixels are so tiny that when they unite they produce a single pixel. It displays as a single speck of color on the screen. Along with the assistance of fluorescent lamps, the television images that we view are created. LCD television can be quite thin and create high quality images. These TVs take up less space and they can even be hung.

LED TV’s also have a flat-screen and use Liquid Crystal Display technology. However their source of light is different. LED TV uses Light Emitting Diodes LED. There are two types of LED back-lighting – Edge lighting and Full-Array lighting. The Edge lighting utilizes a series of diodes are that are arranged along the exterior edges of the screen. The light is dispersed across the screen. Full-Array lighting involves a number of rows of diodes behind the entire surface of the screen allowing for more control over dimming and brightness as the diodes can be switched on and off.

If you are not familiar with the current TV technologies, it can be difficult understanding the choice between LCD and LED televisions. Although LED TV’s and LCD TV’s both use Liquid Crystal Display technology, the key difference is that the LED TV uses Light Emitting Diodes while the standard LCD TV uses fluorescent lamps. When it comes to LCD TVs, Edge-lit television sets are normally lighter and thinner than a Full Array because the lighting source takes up less space. Full-array television sets are thicker and heavier, but one section of the LED panel can be dimmed while other sections stay bright which improves blacks and contrast in the television image. Edge lighting television sets are the lightest and thinnest TVs on the market.

LED TVs are more expensive than LCD televisions. Each type of television has its own advantages and disadvantages. The choice will depend on your needs and television preference.

What is the Difference Between Plasma TV, LCD TV and LED TV?

Over the past decade home entertainment technology has really taken some huge leaps forward. Today, the task of buying a new TV is not just a matter of picking your favourite brand or buying the largest size you can afford. There seem to be more options than ever, and this has certainly led to a lot of confusion among consumers. With that in mind, what exactly are the main differences between the different types of TV, and which is the best?

Plasma TVs are one of the older types of flat screen. They are relatively cheap to produce meaning that prices are generally low for the screen size, which led to plasma becoming a popular choice with consumers who wanted to get the largest screen for their money. These TVs use a gas, which then turns into plasma when an electronic current is passed through it; the plasma then emits the light to create the pictures. This results in a high quality, realistic picture that doesn’t suffer from motion blur. It also offers a particularly wide viewing angle.

However, plasma screens do tend to only have a lifespan of about 10-15 years and do use a relatively high amount of energy, which is now frowned upon as many consumers are trying to become more environmentally friendly. Plasma screens are also quite thick, and are very heavy for their size, so they can be awkward to move. The screen is also fairly susceptible to glare, especially in bright rooms.

LCD TVs can trace their roots back to computer monitors and were first introduced at around the same time as plasma TVs. These TVs use the same basic technology as your pocket calculator screen and are backlit with fluorescent light. They have a much longer lifespan than plasma screens, something in the region of 30+ years, and also use much less power. Traditionally LCD prices were higher than plasma, but as new manufacturing techniques have evolved the prices are now rapidly falling.

While LCD TVs are available in a wide range of sizes, they do offer the worst performance of all the flat screens though, not only do they have the lowest contrast level but they also have a slow refresh rate meaning that motion blur often occurs. The viewing angle is also much narrower than that of plasma TVs, which means that it can be difficult to find a location that offers a good view for everyone, especially in smaller rooms.

LED TVs are actually the next generation of LCD screens, as they are based on a similar technology but use LED backlighting instead of the fluorescent backlighting found in traditional LCD screens. The new backlighting technology means that they are able to deliver a much more dynamic picture quality, they also use significantly less power than even the most efficient LCD TVs. LED screens can be made to be extremely thin, so they offer consumers the ability to place the TV practically anywhere – indeed it is now commonplace to see TVs fastened to the wall in order to save floor space.

As this is still a relatively new development, LED screens do tend to be more expensive than their LCD counterparts. However as LED TVs become more widespread the cost of production is expected to drop significantly, which will be reflected through dramatically lower prices in-store. Having said that, LED technology is considered to be the most reliable of all the flat screen formats so many people don’t mind paying a little bit more.

The world of home entertainment can certainly be a confusing place, especially as new advances in technology seem to come along on an almost monthly basis. Hopefully this article has shed some light on the current generation of flat screen TVs, so at least you can stand a fighting chance the next time you venture into the home entertainment section of the electronics store.

Know the Difference Between LCD, Plasma, HDTV, LED, and OLED

There are many technologies emerging in display devices like TVs. Every technology excels in particular feature of display and has particular method of display. Different technologies used in TVs are:

LCD TV:

Led Lcd

LCD (Liquid Crystal Display) televisions are thinner and lighter and provide much sharper and clearer picture than CRTs of similar size. They are ideally used for cell phone displays, computer monitors, and to view still images. LCD TVs have a flat screen so there will be no picture distortion and don’t have screen “burn in” like curved tube TVs. In general, LCD viewing angle is 175 degrees. The picture can be viewed 87 degrees from each side. LCD TVs are very economical to use and screens less than 35 are fairly inexpensive. LCD TVs are backlit and blocks outside light. So, they are suitable for natural lighting situations. Most LCD TVs have a half lifespan (50% of original brightness) of over 30,000 hours (16 years of viewing at 6 hours per day). LCD sizes generally range from 13 to 65 but some manufacturer will offer up to 100 sizes.

Plasma TV:

A Plasma Display Panel (PDP) is a flat panel display used in large TV displays. They have better and accurate color generation than LCDs, and with far display, wider viewing angles, and do not experience degradation at high angles compared to LCD. Plasma displays are ideal for viewing motion video in large displays.

· Plasma screen sizes generally ranges from 32 to 84 but some offer screen sizes up to 100.

· Plasma pixel, technology provides a brighter picture with more contrast between the blacks and whites than standard TV.

· In general, plasma TVs viewing angle is 160 to 180 degrees and picture can be viewed from any angle.

· On an average, Plasma TVs have a half lifespan (50% of brightness) of 50,000 to 70,000 hours (20 years of viewing 6 hours a day to 50,000 hours).

Some plasma TVs are provided with upgradeable video cards that helps to match with future technology.

HDTV:

HDTV or High-Definition Television is a digital television broadcasting system offering a higher resolution compared to regular television systems. HDTV is digitally broadcast unlike earlier analog broadcasting, because digital television (DTV) signals require reduced bandwidth because of digital video compression.

HDTV will not have standard TV problems, like low quality sharpness, troubles with brightness or contrast, spots, other visual, or audio imperfections, problems like double images (ghosting), and weak signals. HD television provides clearer pictures with excellent sound quality, a wider viewing screen and up-to-date scanning. HDTV will provide more and superior channels provided by regular satellite or cable television with theater system experience.

LED TV:

LED (Light Emitting Diode) TV is an LCD TV that uses LEDs for back lighting, instead of using the fluorescent lights (as it creates more black spots). They are ideally used for low-energy indicators, as substitutes for traditional light sources in general lighting and automotive lighting.

· LED TV currently costs more than a standard LCD or plasma TV.

· LED TV has got great looks and very easy to Install.

· Edge-lit LED television will consume 30-40% of less power than LCD or plasma TV. But backlit LEDs will consume more power.

· Brighter picture can be viewed with LED television compared to a standard LCD TV.

· LED TV that is backlit, with local dimming and RGB LEDs, will have an enhanced picture and better contrast ratio and colour accuracy compared to standard LCD TV.

It has a long lasting life and also eco friendly.

OLED TVs:

OLED (Organic Light Emitting Diode) TVs depend on light emitting polymer technology. Its features including,

· In OLED TVs, there is no need for backlights or extra heaters or coolers, so there is less power consumption.

· As OLED materials has the capacity to support full spectrum of visible light, so there will be higher contrast and it has high-speed refresh rates.

· OLEDs are much faster than LCDs. Fast motion and quick eye movement pictures are more realistic. And OLED TVs will make virtual images to look realistic and can be viewed easily for longer periods.

· It has larger viewing angle and for near-eye applications, it provides more pleasant viewing without distortion.

One disadvantage with OLED TVs is the limited lifespan of the organic materials used in its manufacturing. In addition, blue light degrades quickly with a lifespan of 14,000 hours (when used 8 hours per day for five years) on flat-panel displays.

Before purchasing a television, know the difference between each technology and purchase the one, which has your desired features and suits your budget.
