Do not know what is the difference between LCD TV and OLED?

Tencent appliance compiled over the past 10 years, people have been entangled in the "buy a plasma or LCD TV, and now, the plasma has been completely out of the market, in addition to the field of liquid crystal LED/LCD, also derived from the new quantum dot backlighting technology. The only exception is the use of organic light-emitting diode OLED technology, and liquid crystal is completely different.

From a certain point of view, OLED due to self lighting, the characteristics of each pixel independent lighting, image quality is more outstanding, as a substitute for plasma. Of course, because of the cost, the development of OLED TV is still expensive, while the LCD TV will not sit still, to enhance the display effect through a large number of new technology.

So, from all aspects of detail, which technology is better? Although we usually think that OLED represents high quality, but there are some shortcomings. So below, we come from the details, look at the fundamental differences and differences between LCD TV and OLED tv.

1 brightness

Winner: LCD

Especially the LCD TV LED TV, with a variety of backlight design, such as the bottom, top and bottom, side light type, global type and so on, have relatively higher brightness, while OLED can be self luminous, but compared to the LED backlight brightness slightly lower.

2 black level

Winner: OLED

Black level, since each pixel of the OLED is independent of self luminous, color performance is more profound, natural. No matter what kind of LCD TV backlight technology used in the realization of local dimming will have some impact on the reduction of the impact of black.

3 contrast

Winner: OLED

You may use the LCD TV or display is bad, it is found that the effect of color white, very accurate, this is basically because of poor condition caused by contrast. In addition, the contrast will also affect the black level to a certain extent. Although the contrast test is rarely tested in television, OLED, in contrast, produces a better contrast effect, without any.

4 resolution

Winner: deuce

Whether it is LCD or OLED TV, the highest resolution standards have reached the 4K ultra high definition standards.

5 refresh rate and motion blur

Winner: LCD

Relatively speaking, the LCD screen has a higher refresh rate and motion blur, and the current version of the OLED is generally more obvious effect of motion blur. Cnet test found that even if the use of black frame insertion technology to solve the motion blur, LCD TV performance is generally better than OLED.

6 high dynamic range (HDR)

Winner: LCD

HDR is a technology that may significantly improve the quality of the image, in contrast, brightness and balance have outstanding performance. Currently, only a very small number of LED TV support this feature, and the need to be compatible with HDR image content (such as 4K Blu ray) in order to get the best results. And OLED, although LG has demonstrated the HDR technology, but its 2015 models do not really have this feature.

7 color gamut expansion

Winner: LCD

Another widely used technology for this year's television is the color gamut expansion. For example, the popular quantum dots, you can let the TV show a wider range of colors, in order to achieve a different display style or enrich their own color effects. As for OLED, the current LG technology to use the blue and yellow phosphor and RGB color filter to create a ATSC color spectrum, whether the future can realize the gamut expansion is not clear.

8 visual angle and uniformity

Winner: OLED

Although IPS, curved screen technology can improve the perspective of the LCD screen, but there are still some dead. OLED does not have any perspective, and even from the extreme point of view are basically the same.

Uniformity refers to the consistency of the screen backlight, OLED due to the characteristics of self luminous performance is more uniform, while the LCD backlight because of the different position of light leakage in a certain extent, especially most of the side light type LED.

9 energy consumption

Winner: LCD

LCD TV energy consumption depends on the backlight settings, so the LED backlight design than each pixel independent light-emitting OLED more power saving. According to the Cnet test, the use of LED technology 55 inch LCD TV power consumption cost of about $14 (about RMB 87 yuan), LG OLED TV with the size of $45 (about RMB).

10 life

Winner: deuce

Any flat-panel TVs are likely to appear "burn-in" phenomenon, which is a permanent residual image. However, this is a small probability for the LCD screen, OLED is also not sure, in short, we do not use the TV in the process, showing a fixed image all night. As for the life, whether it is liquid crystal or OLED, there is no authoritative life data statistics, the industry generally believe that the difference is not large.

11 price

Winner: LCD

Obviously, LCD TV is much cheaper than the OLED TV, the highest cost gap may reach 5 times. However, OLED TV is becoming cheaper and cheaper, which is worth paying attention to.

summary

Obviously, whether it is liquid crystal or OLED, have their own advantages. From the current point of view, OLED in image quality, contrast, etc.
