You don't know the secret: LED TV "family" concept out

Concept elaboration

Television from the CRT era into the era of LED, LED TV industry has become the most common terms, LED TV from the beginning of the novel into the common people's home now, but only a few years time.

Since 2012, OLED TV back to the television industry, Hisense and SKYWORTH in 2014 launched UED TV and GLED tv. A new member of the LED family one after another, a new concept is a cause of concern. But LED, OLED, ULED and GLED were nothing but the ordinary people confused. Today, we come up with a clear definition of the above four, and a simple comparison.

LED TV

We often speak of the LED TV is a backlight, LED TV with LED as light source is a kind of TV, LCD TV, it uses the LED backlight source to replace the traditional fluorescent lamp, the TV screen display effect is more outstanding, while the body is more thin. LED is called "Light Emitting Diode", which is a kind of semiconductor component. LED is very sensitive to the current, the current can make it very light, and long life, can be a long time flicker without damage, so the development of television to the LED era after the service life is greatly increased.

OLED TV

OLED TV is a TV with OLED screen as display screen. OLED is an organic light emitting display technology, consisting of a coating of organic material and the glass substrate is very thin, when the charge through the organic material coating when the screen will light, light color is decided to rely on the organic light layer material. OLED technology is divided into polymer PLED and low molecular OLED, at present, we say that the basic use of low molecular OLED OLED TV technology.

Since the OLED technology to achieve self luminous, so the use of TV products do not need to set up a backlight, so OLED TV screen technology to define.

ULED TV

The concept of ULED TV was proposed by Hisense, a domestic color TV company, in 2013, in which U is not a new display technology. Here U abbreviation for Ultra, meaning ultra high, extreme, even better, more extreme LED tv.

ULED backlight TV through the area dynamic control technology, and the fusion of HiView image painting engine ultra high-definition display perfect presentation, unique advantages to achieve high contrast, high color gamut and high response. Therefore, we can see that, in fact, ULED TV is to enhance the image quality by improving the backlight.

GLED TV

The concept of GLED television is put forward for the first time in August this year, SKYWORTH, where G means Geek, translation is "Internet TV geeks", it can be seen, LED, OLED, GLED TV and ULED are different, it not only represents the TV picture quality is mainly from the point of view of television application experience.

Concept distinction

From the first part of the concept can be seen in the carding: we usually speak of the LED TV is defined as a backlight, and LED TV can also be subdivided into LCD TV and LED TV (where LCD and LED are screen).

OLED TV refers to the OLED as the screen of the TV, because the OLED screen can be self luminous, so it can be seen as a screen and backlight.

ULED is the use of more sophisticated backlight technology to improve the TV screen, from the nature, is still classified as LED tv.

GLED TV is not the definition of TV quality or display technology, but from the actual operating experience of the TV set, joined the application part.

Comparison of advantages and disadvantages

Comparison between LED TV and OLED TV

Compared with OLED, LED wins in the technical maturity, high yield, low cost, becoming the first choice for television companies. The OLED technology is still immature, and the cost is relatively high, the average user is still difficult to accept.

From the quality of the products, OLED TV picture quality is more excellent, can provide the most vivid colors for the user, and the hanging look comfortable, while TV can through their own adjustment to correct the TV screen to achieve excellent effect; OLED screen is thin, flexible, beautiful product of more than.

OLED is the characteristics of their own light, unlike TFT LCD backlight, so visibility and brightness are high, followed by low voltage demand and high efficiency, fast response, light weight, thin thickness, simple structure. OLED display is extremely thin, very tough, it tends to bend, so it is very suitable for surface TV display.

Comparison between OLED TV and ULED TV

The advantages of OLED TV needless to say, the biggest drawback is the low yield, high cost.

In comparison, the shortcomings of ULED model through the use of TV backlight to compensate for the LED screen, the picture of the performance of its millions of contrast, the ultimate gorgeous color, viewing comfort and other advantages can be almost with OLED a level, but its price is far lower than the OLED tv.

But from another perspective, ULED TV is still a LED TV, and OLED is known as the next generation of display technology, from the perspective of industry change, ULED is also bound to quit the stage before OLED.
