Screen technology which strong? Comprehensive comparison of OLED and LED LCD

For the display technology, 2016 will be a significant year. With the popularity of 4K and the emergence of new features, such as HDR, television can be seen as the viewing experience will be further improved. In the field of mobile phones, screen resolution upgrade also brings a more subtle display.

But as we prepare for the new technology, there are two types of war between the display panel types, which are LCD and OLED. The former is the most popular type of display panel, our common LED TV is actually used with LED backlight LCD panel. The OLED is a completely different panel type, it is currently used in some mobile phones and tv.

Some people call OLED the future trend, but is it really better than the LED LCD panel?

Difference

The LED LCD panel uses a backlight to light the pixels, and the pixels of the OLED are independent of the light. As a result, the brightness of the OLED panel can be achieved by one pixel control, which is not done by LED LCD.

In some cheap TV and LCD mobile phone screen, LED backlight used in LED LCD is actually on the display side rather than the rear, they emit light through the red green and blue pixel at our glasses. Therefore, LED LCD panel brightness control is limited. When in a dark environment, you will find that it is not shown in black black.

contrast ratio

The OLED panel will not emit any light in the black display, so it can achieve the contrast of the infinite, and a LCD panel contrast good quality may be only 1000:1. The "dynamic" contrast shown on the LCD TV is generally higher than that, because it refers to the ability of the TV to adjust the backlight level according to the screen content, not the actual contrast.

Some LED LCD panel can actually achieve close to OLED contrast, such as straight down LED. The LED backlight of the panel is placed directly on the back of the LCD, thus achieving a more accurate brightness control. This kind of panel generally only high-end TV will be used, but the effect is good or bad.

It is worth noting that the straight down LED TV can only control a LED area or group, still can not achieve the pixel level control such as OLED. When you watch 21:9 movies on 16:9 television, black side direct type LED can well deal with the picture, but in the more complex task, its performance is not so good, as shown in black background under the bright object, you will see a halo effect. This is because the backlight region and the screen contents do not match.

Display effect

In terms of overall performance, OLED and LCD have the ability to show excellent picture quality. HDR is the main push in the field of television in 2016, and in order to establish the relevant standards, the TV industry launched a new "Ultra HD Premium" logo. It is worth noting that both LCD and OLED TV have been awarded this logo. That is to say, the two display technology has the ability to show the top quality.

Because of the excellent contrast, OLED display is the best choice for you to watch the contents in the dark room. This is particularly important given the fact that plasma TV has withdrawn from the stage of history. For the pursuit of the ultimate quality of the picture, OLED display is also a great choice, not only in the field of television. Samsung has just released Galaxy S7 and S7 edge two phones are using the OLED panel, and their display may be the best in the smartphone.

Popularity

If the quality of the OLED is so good, why OLED TV is still not popular? This is mainly because the production of this panel is very difficult. Up to now, only three companies have the ability to produce a full-size commercial OLED TV, which are Samsung, LG and panasonic. But the camp should be further expanded this year. PHILPS is currently rumored to be developing OLED TV, is expected to be officially released this year.

Samsung's OLED TV model is KE55S9C, the initial price of 7000 pounds (about RMB 64847). At such a high price, the TV should provide you with the perfect experience, but it's a bit of a blue LED - they have a shorter life expectancy than green and red LED.

Through the use of white LED and color filters, LG successfully solved this problem in its own OLED tv. In the popularization of OLED work, the South Korean manufacturers are also very hard. Although OLED TV is still not mainstream consumers can afford, but LG's attempt to do is for all to see.

At present, the cheapest OLED LG TV is 55EC930V, priced at about 1299 pounds (about RMB 12034). Although the product quality is good, but does not support 4K, it has become somewhat outdated. But if you want to buy a 4K OLED TV, then prepare a budget of at least 2000.

As for LCD TV, you can only spend less than 500 pounds will be able to buy a 4K LCD TV, and the cheapest 4K OLED TV needs $2499 (about 23150 yuan, LG 55EG960V). Although the latter price is still high, but compared to a year ago, the cheapest 4K OLED (LG 65EC970V) has been much cheaper.

Although the price of OLED TV is still relatively high, but the continued investment in technology vendors will significantly lower costs. By the end of this year
