What is the difference between LCD and OLED contrasts?

- May 08, 2018-


In the past 10 years, people have been struggling to "buy plasma or LCD TVs." Now, plasma has completely withdrawn from the market. In addition to LED/LCD, the liquid crystal field also derives new backlighting technologies such as quantum dots. The only exception is the use of organic light-emitting diodes OLED technology, completely different from the liquid crystal.

From a certain point of view, because of the self-illumination and the independent lighting characteristics of each pixel, OLEDs are superior in image quality and are considered as plasma substitutes. Of course, due to the cost relationship, OLED TVs are still expensive to develop today, and LCD TVs will not be overwhelmed by a lot of new technologies to enhance the display effect.

So, from a variety of details, which technology is better? Although we generally think that OLEDs represent high image quality, there are also some drawbacks. So, let's take a look at the details to see the fundamental differences and differences between LCD TVs and OLED TVs.


Winner: LCD


LCD TVs, especially LED-backlit TVs, have a variety of backlight designs, such as bottom, top and bottom, sidelight, global, and so on, which have relatively higher brightness, while OLEDs can emit light spontaneously, but they have a brightness aspect. It is slightly lower than the LED backlight.

2. Black level

Winner: OLED


In terms of black level, since each pixel of the OLED is self-illuminating independently, the color performance is more profound and natural. Regardless of which kind of backlight technology is used in the LCD TV, it will have some influence in achieving local dimming, which will affect the restoration of the black effect.

3. Contrast

Winner: OLED


Perhaps you have used a bad LCD TV or monitor, you will find its effect is white, the color reduction is extremely inaccurate, which is basically caused by poor contrast conditions. In addition, the contrast also affects the black level to some extent. Although contrast items are rarely tested in TV evaluations, relatively speaking, OLEDs can produce better contrast without any smudging.
