Since the early 1900's, television sets have been drastically changing in both display and design. The television started with what is called an analog signal. This is the analog transmission broadcasting of both analog audio and analog video signals. Analog television can be wireless or it can require the use of copper wire. This was all displayed in black and white. Before this stayed in effect, the television evolved once again in the middle of the 1900's. Around 1950, the digital television was introduced. Digital television is the transmission of audio and video by digitally processed and multiplexed signals. Fast forward to the current day and you will see the now king of television the LCD screen. It does not stop here however and soon the LED-back lit LCD screens took over the market. This is a flat panel display that uses LED backlighting instead of cold cathode fluorescent backlighting used by other LCD screens. The images produced by these babies are in vibrant lustrous color. These two types of television sets have advanced the most in the shortest amount of time.
The Samsung un60eh6000 is a powerful piece of technology. Sporting a 60 inch 1080p 120 hertz LED display screen and a clear motion rate of 240 you are guaranteed to be satisfied with this one. To ensure you are getting those beautiful high definition colors, the Samsung un60eh6000 comes with wide color enhancer plus. This allows you to witness the entire RGB color spectrum as if it were right in front of your eyes. The colors also come off as natural so they do not have that contrasted tone that most plasma televisions have. This TV also comes with ConnectShare Movie which lets you watch videos, play music or view photos from a usb drive. Coming with HDMI ports for connected AV devices is a major plus to anyone who enjoys playing video games or watching movies through their Blu-ray DVD player. If you are not into all that then don't worry because the Samsung un60eh6000 also has a component in port and a regular digital audio video output. These are all new features that analog and digital T.V sets did not have. The LED screen is powered by a thin film of transistor liquid crystal as opposed to the analog or digital signals emitted by older television sets. These kind of TV's also have local dimming effects which allows the colors to show as they truly should. This lets blacks be inky and dark and whites come off as flashy and clear compared to a digital television where colors are always at their base value.
While sharing many of the advanced specs that LED screens have, the Vizio e701i-a3 is slightly larger. This LED-LCD screen is a whopping 70 inches. That's at least 10 inches bigger then most old school big screen TV's. Remember those ones, the ones with the projection stop lights and came with mineral oil in them to cool down the internal components. Some even had antifreeze in them to keep them cool. It seems almost like ancient technology at this point. Now we have LED screens that not only are vibrant in color, but have an eco friendly video setting that saves electricity. Some of these screens even turn themselves off after a short period of inactivity. Well the Vizio e701i-a3 comes with 1080p for full high definition pictures.
It also has network connectivity, something we have not ever seen in older TVs. This means it can connect to the internet via Wi-Fi connection or a broadband Ethernet connection. The internet capabilities it comes with are as follows, Vizio Internet Apps, Netflix, Amazon Instant Video, Vudu, Hulu Plus, Pandora, YouTube, Facebook, Flickr, and even Twitter. Now that's pretty impressive. You ccan browse your favorite websites without ever leaving your couch. This is possibly an alternative that could replace computers for some families. This TV is even Energy Star qualified. Older television sets just kinda turned on and would suck your electricity by the hour where as these newer eco friendly T.Vs can be left on for hours and only drain a fraction of what the older models would have taken up. Not by small number either. An old digital TV could take up as much as 240 dollars a month where a newer model of LED T.Vs can take up only a whopping 14 dollars. That is a huge difference.
Now since the first LED TV was introduced back in 2009, it was boasted by most promoters and advertisers as being a new form of technology. Technically it is not, but it is more of a welcomed revision to the original LCD screens. An LED screen is a LCD screen that uses a different type of backlight that is made up of light emitting diodes that replace a fluorescent lamp used for lighting up the picture. LCD screens are made of colored pixels and do not create their own light which is why they need their own light to produce the pictures. Along with LED, LCD, and LED-LCD TVs there were Plasma TVs. Plamsa screens had phosphors that made their screen light up and produce color when zapped with electricity.
This is drastically different from plugging your digital TV and turning it on. The image displayed by the digital television is made up of digital MMDS. This is multi-channel multi-point distribution service. You can also call it wireless cable. The technology in television sets has advanced vastly since the early 1900's. In the years to come, the technology of TV is only going to further itself and provide a whole new experience for every user. With all the advancement they are receiving, it isn't even surprising that three dimensional televisions are being made now and glasses free three dimensional TVs being made. In the next 50 years, it will be amazing to see just far this hardware can go and what new limits it will be able to reach.
