OLED shopping LED winner to you

OLED TV has been widely recognized as the next generation TV development direction of this technology, consumers are not unfamiliar, mobile phone since 2001 began to use OLED screen technology, because of the recent LG and Samsung launched a new generation of OLED TV, attracted a lot of attention of consumers, the ratio of OLED LED or LCD TV what advantage? What are the disadvantages of OLED over the latter?

LED technology?

LED is the abbreviation of diode (light emitting diode (light-emitting)), is a semiconductor component, the current through it can make it shine, although the size is not as compact fluorescent and incandescent lamps, but very bright. However, because the volume can not be as small as the pixel level, so they are only used as LCD TV backlight.

OLED technology?

OLED is the abbreviation of organic light-emitting diodes (organic light-emitting diode), which uses a very thin organic material coating and glass substrate, when the current is passed, the organic material will shine. Compared with LED, it can be done very thin, small and flexible. In addition, OLED TV, each pixel lights can be independent of other lights.

Which is better?

But from the image quality, OLED TV is much better than LED/LCD, but considering the image quality is not the only consideration, it is necessary to come to the conclusion of a one to one analysis.

Black expressiveness - OLED win

A deep, dark, black screen performance is an important factor to make excellent image quality, the more deep black can show greater contrast and richer colors, more realistic and dazzling visual effects, the OLED performance is better.

LED TV with a LED backlight hiding in LCD flat back, even with dimming technology advanced, can not produce surprising black, there are other common local edge leakage phenomenon.

OLED will not, if it can not get the current, will not produce any light, but become black.

Brightness - LED/LCD win

LED in the ultra light just above some advantages, OLED TV can also become bright, but long time you start pixel brightness of adjusting it will not only reduce the pixel unit life time will become black in need of a little slow.

Color gamut - OLED win

The recent production of OLED TV can cover a very wide color gamut, than LED, LCD TV to have the advantage, in layman's terms, they can produce a more subtle color range in the visible spectrum.

Response time - OLED win

Although the LED/LCD has improved greatly in the past few years, but OLED can be an easy job to do victory, the new OLED provider actually the fastest response time and the corresponding technology, and the corresponding time to a faster decrease of image motion less fuzzy.

Viewing angle

At present, this is a difficult topic, in the United States to buy the TV are curved, if the future of curved surface mask. From the point of view of its self luminous rather than LED/CD backlight, OLED should have a more perfect perspective.

At present, the surface of the screen seems to have some complications, such as the edge of the corner of the screen more than the middle width, a little trapezoidal effect. The horizontal edges are also wider, with a slight U shape at the top, and an inverted U shape at the bottom. But this should be a lot better for flat.

Size - LED/LCD win

Now the size of the OLED TV is limited to 55 inches, and SHARP has been able to produce a LED/LCD of 90 inches, and the price is the same as the more than and 50 inch tv.

Service life - LED/LCD win

OLED is currently unable to confirm that it has a long life, and the compound used to create the blue pixels of OLED has been told that the luminescence lifetime is short, and a picture of a color that does not respond to other colors will be out of balance. Samsung's approach to this problem is a specific unit, the blue pixel is two times the size of other pixels, to reduce the voltage applied to it. The method of LG is to make the white OLED through the grid, and then cover the filter to generate red, green, blue and white pixels. These technologies temporarily put together, but depends on the user's actual life expectancy to quit effect. Therefore, we temporarily select LED/LCD, its life is obvious.

LED/LCD burn-in win

From the burn-in CRT TV, when it is a long time to display a static image will leave a shadow on the screen. This is the same phenomenon in plasma and OLED TV, but it's not a big problem if you don't abuse the TV for a long time and watch a channel.

In this regard, LED/LCD TV is not easy to aging, all because of their own technology to win in this regard.

Weight, power consumption - OLED win

The OLED panel is thin and does not require a backlight, so it is thinner and requires less power.

Price - temporary LED win

The next OLED TV will cost you $9000 (Samsung) and $15000 (LG), the next few months, the price of LG must come down, otherwise consumers will stop. Of course, $9000 is not cheap. Other types of TV can only buy half an inch of 55-65 inch tv.

Vision may be insufficient budget in recent years, then, the possibility of users choose more LED/LCD tv.

The last winner?

Image quality, OLED, plasma than LED/LCD are better; cost-effective
