Use LED TV, Is More Energy Efficient?

One of the jargon that is always carried by TV producers who use screen LED (light emitting diode) is a matter of saving energy. Claimed, LED TV is the most efficient type of television than any other television currently available, ranging tube TVs, plasma, or LCD (liquid crystal display). Is this true?

Seen from the perspective of technology, according to experts from the electronics Electronics and Telecommunication Research Center Indonesian Institute of Sciences (LIPI) Masyuri, LED TV technology is much more efficient. "Power savings can be very significant," he said.

When compared with the TV tube, the LED can save power up to 50 percent. Meanwhile, when compared with LCD TV, LED TV could save 20-30 percent power. That was caused LED TVs using LED lighting from lower energy consumption.

However, Masyuri said that the energy consumption of LED TVs can not be compared absolutely. Growing trend in communities around the TV size selection also needs to be seen. Now, when people buy a LED TV, they did buy a large.

"Now, see if you buy a 42-inch LED TV, it's almost the same energy consumption ukurang 14 inch tube TV, maybe even more. So, LED TVs can only change the trend in the search for television," he continued.

In addition, the price of LED TV is still more expensive than other types of televisions. However, it will pay off with a more brilliant image quality. With LED, detailed images can be better than other types of televisions.

Masyuri stressed that the most important thing in choosing a television is to look at the information contained in the television packaging, primarily a matter of power. Masyuri also stressed the need to use television effectively, for example by turning it off when not watched.

The difference of LCD and AMOLED screen in Mobile

With the increasingly widespread use of large touch screen as the primary input device on mobile devices, the display quality becomes increasingly important because it determines the user's convenience in using the gadget in question.

Various terms such as AMOLED, IPS, and the Retina display is used as an appendage specific device display technology to attract buyers.

However, in general there are two main types of screens used on most mobile devices, namely LCD and AMOLED. Differences following advantages and disadvantages of both will KompasTekno cover in this article.

LCD

LCD or Liquid Crystal Display has been used as display a wide range of devices for decades, ranging from computer monitors, screen smartphone, to watch.

As the name implies, the LCD screen using the medium of liquid crystals sandwiched between a couple of panes of glass or other transparent material.

When seen from very close range, the units seem pixels of red, green, and blue that make up the image on the LCD screen.

Some LCD screens using the technology In-Plane Switching or IPS to improve color reproduction and viewing angles wider optimal. Screen "Retina Display" property of the iPhone 4/4s for example, is the LCD screen with IPS technology that has a high resolution.

Color LCD display capable of reproducing very realistic, but requires additional torch light (backlight) because it does not produce its own light.

Some of the popular devices that use LCD screens: iPhone 4/4s, iPad, and HTC One X

AMOLED

Technology AMOLED or Active Matrix Organic Light Emitting Diode actually been around a long time, history extending up to decades of the 50's.

Later, this type of screen is applied in the bustling gadget devices because it has some advantages over LCD as it does not require backlight lamp and has a higher contrast.

AMOLED is made of a thin layer of an organic polymer that lights up when powered. Because of the simple construction, AMOLED display can be made ​​very thin.

Most of the AMOLED screen has a pixel structure called "PenTile display", in which the two sub-pixels of red and blue larger size and placed between two sub-pixels, green normal sized. With kemikian, its pixel array to 'Red-Green-Blue-Green (RGBG), not Red-Green-Blue as the LCD.

The advantage of the "PenTile display" is a bright AMOLED display screen can be made conventionally with only one-third the number of sub-pixels are usually required.

The drawback, due to the size of the sub-pixels of red and blue larger, the screen looks "grainy" or looks like it has a low resolution, even though it is not the case.

AMOLED screens are usually difficult to see under direct sunlight beam, but the technology Super AMOLED Plus from Samsung that does not use the "PenTile display" has given improvement in this regard.

Some of the popular devices that use AMOLED screens: Samsung Galaxy S series, the Nokia Lumia 900, and HTC One S.

Samsung Ready to Show off "Display Bent" for Mobile

Samsung Display, a subsidiary of Samsung Electronics, is rumored to be showing a flexible display in the exhibition Consumer Electronic Show (CES) to be held in Las Vegas, USA, in early January 2013.

Flexible display technology is generating the kind of screen that can be bent. Later, maybe a screen that uses the technology will be used in televisions or smartphones in the future with a radical design concept.

Visitors to the exhibition CES 2013 will get to watch a pair of display panels from Samsung. The first is a flexible screen measuring 5.5 inches with a resolution of 1280 x 720 (267ppi) is designed for smartphones. In addition, Samsung also will exhibit a 55-inch screen size for television.

According to information from Samsung is quoted by Cnet, the company's flexible display can be bent without breaking, but it can not be rolled up.

Besides making the main material of the flexible display, the creators must also make touchscreen panels and cover layer into a single unit on the screen.

Samsung itself has developed a flexible display for some time. At CES in 2011, electronics manufacturers are on the rise this demonstrates a similar screen size smaller, 4.5-inch, with a pixel density of 200 ppi.

With the model "crooked screen" larger size which will be showcased at CES 2013, Samsung is apparently trying to keep the design screen in order to stay up-to-date with mobile trends.

Apple Patented Connectors 'SIM Card' Easy Pull

  Never enter the wrong SIM card and difficulty removing it again? With a new type of connector from Apple, it will not happen again.

Unfortunately, perhaps only Apple device that could use this type of connector it. This is because the company concerned has obtained the patent number 8,337,223 on the connector from the Patent and Trademark Office of the United States (USPTO), Tuesday (12/25/2012) then.

Connector, according to the description in the patent, "Allow SIM card is inserted and removed easily using a mechanical lever, and able to prevent the damage from one card inserted."

Types of connectors that can be installed on iPhone, iPad, MacBook Pro, or even the television is able to accommodate a SIM card from a variety of sizes, including the SIM card "regular" Mini-SIM or Micro-SIM.

Apple originally filed the connector to the USPTO in the third quarter of 2010. Three inventors names listed on it is Zheng Gao, Benjamin Rappoport and Seteve McClure.

Quoted from Engadget, Apple's patent on the SIM card connector technology has the potential to inhibit other manufacturers to adopt similar technology because it can be a problem with Apple.

Earlier, in mid-2012, Apple managed to make the design of nano-SIM card is accepted as the standard of his, defeating the design results from Nokia, Motorola Mobility, and RIM.
