Which technology of OLED or quantum dots will change the future life?

From LED to OLED, from 3D to 4K, from Internet TV to smart TV, the field of color TV has never lacked new ideas. At the end of 2014, following the OLED, Quantum-dot TV began to enter the market. Domestic and foreign brands launched quantum-dot TVs. Samsung even once stated that it would not continue to produce OLED TVs, instead focusing on the development of quantum dot technology.

The two technologies of OLED and quantum dot will undoubtedly become the two mainstream directions for TV development in the future. There will be thousands of users who will live without them. In the face of such a situation, you can't help but wonder: Which is better? Xiao Bian will discuss with you today about these two technologies that are likely to change your life in the future.

The first Quantum Dot TV (QLED) was born in 14 years. We all know that the traditional liquid crystal display is composed of two polarizer plates and two glass plates plus liquid crystal in the middle, plus a backlight source, so that the liquid crystal can change the direction of light as long as the power is applied. The so-called quantum dot television actually replaces the LED backlight with a "quantum dot" material, which is a tiny inorganic nanocrystal that emits pure, colored light and is colored by quantum dots when stimulated by light. The size and material of the decision (specifically, please understand Baidu). The biggest advantage of QLED TV is high color gamut and extremely pure color expression.

On April 7th, yesterday, TCL launched three Quantum Dot TVs, claiming that the display is more effective than OLEDs. So is the fact as he said?

The birth of OLED is one year earlier than QLED. Although the name has the word “LED”, it does not belong to LCD TVs. The fundamental difference is that OLED TVs do not need backlight. The RGB color signal is directly displayed by an OLED diode with a self-luminous characteristic, and there is almost no problem with the viewing angle of the liquid crystal. One month ago, the Internet brand Kukai launched an OLED TV, which was the concept of “black aesthetics”. The reason is that the self-luminous nature of OLED allows it to present a near-perfect “black” and the display effect is outstanding.

Then the question is: What kind of technology is more outstanding and more likely to become popular?

OLED was once considered to be the mainstream of next-generation display technology, but it was limited by technology and cost. Although LG strongly promoted it, it was still a long way from popularity, and as a result, manufacturers have sought breakthrough points in other areas and invented it. QLED, ULED, GLED, etc. (It is worth mentioning here that the Coolopen T55 OLED is the world's first million-dollar OLED TV).

Will quantum dot technology become the next popular display technology? TCL claims that its quantum dot display technology has surpassed OLED in various dimensions such as color gamut coverage, color control accuracy, and red, green and blue color purity. "It is regarded as the commanding height of global display technology, and it is also seen as influencing the global display. The technological revolution, but actually quantum dots TV has a great limitation in terms of image quality, color conversion, thickness design, etc. And its biggest advantage, "high color gamut," in actual use, the data show that more than 85% of the naked eye It's hard to tell, so it's unknown whether users will pay for it.
