After the "Quantum Light Shine Horizons - 2017 International Quantum Dot Display Industry Development Forum" was held in Beijing, the Samsung Quantum Dot Alliance was officially established. The change in this situation has made the "QLED" and "OLED" enthusiastic fans once again pushed to the forefront of the future display technology battle. Although there is only one letter difference between QLED and OLED, there is a huge difference in technology and effect. What are the differences and origins between them? The arrival of Samsung QLED TV undoubtedly put an end to these two contests in advance.
The quantum of "quantum dot" technology has been continuously rising, and it has received great attention from the industry and has occupied a higher position in the industry. In fact, as far back as the 1970s, research on quantum dot technology has begun, and nearly half a century of technology has been ploughed. At this stage, quantum dot technology and applications are constantly maturing and upgrading.
Quantum dots are a very advanced nanomaterial, and the use of quantum dot materials in backlights has four unique advantages:
First, the longer life due to the use of mature inorganic materials, fluorescent longer life, it is reported that the quantum dot material life of TCL can reach 60,000 hours, so do not worry about product life.
Second, the wider color gamut The quantum dot technology has increased the color gamut of the LCD by 38% without increasing the CF film thickness. At present, the industry generally adopts the NTSC color gamut standard to measure the effect of color display. The wider the color gamut, the richer the range of colors presented by the TV and the more reflective the true nature of things.
Third, the color is more pure With the help of quantum display materials, the spectral peaks corresponding to the three primary colors of red, green, and blue displayed by QD TV are clear and without overlapping with each other, bringing the most pure color expression.
Fourth, the higher brightness of quantum dot display materials can significantly improve the LCD brightness, saving energy. Quantum dot technology will effectively solve the high color gamut caused by traditional methods but low brightness, while high brightness must increase the number of LED chips and increase the energy consumption and cost dilemma.
Authoritative test results show that the quality performance of QD TVs is comparable to OLED TVs, and individual indicators are more prominent than OLED TVs! Next we come to a PK to see who is more dominant in each quality factor.
1. Color gamut: Q wins. However, quantum dots have a natural advantage in their spectra, especially when displaying red and green, QLEDs have a more intense color appearance.
2, brightness: Q wins. The LED backlight used by QLED can further increase the brightness by adopting a high-brightness LED module and improving the structure of the backlight. Samsung's QLED TV can reach 1500-2000nit, and can guarantee about 15s does not decay. The characteristics of organic light emission of OLEDs, high brightness is bound to attenuate the organic light, resulting in irreversible physical damage.
3, black field details: Q wins. Dark detail and color transition issues Whether it is W-OLED or RGB OLED should be an unavoidable problem. Because OLED adopts PWM or DC dimming method. When the color number of the panel reaches 10 bits, that is, 1024 levels, it is quite difficult to imagine the fine control of the liquid crystal molecules.
4, refresh rate response time: O wins. The liquid crystal molecules of the QLED have a mechanical rotation after receiving the electrical signal, and the OLED, just like a light bulb, completes the switch closing action instantaneously.
5. HDR: Q wins. QLEDs have higher brightness, so QLEDs will have better dynamic range performance at the same color depth and grayscale.
6, uniformity: O wins. The OLED alone controls the light emission characteristics of each pixel and has better picture uniformity.
7, power consumption: Q wins. OLED saves power when displaying black scenes. However, under normal use conditions, OLEDs of the same size will have more power than QLEDs.
8, price: Q wins. The thermal evaporation process used in OLEDs is difficult, and QLEDs are very mature.
In the seven quality testing sessions, QLED led OLED with a score of 5:2. QLEDs are particularly advantageous in areas such as color gamut, brightness and HDR where consumers are particularly concerned.
The representative product of QLED display technology is Samsung QLED TV. It upgraded the third-generation QD TV to a metal-free QLED light quality sub-dot TV. Its peak brightness has been greatly improved, reaching as high as 1,500 to 2,000 nits. It can guarantee full color performance without attenuation, and it has nearly unlimited value. The image life.
The most remarkable feature of this series is that it can not only accurately represent the color space of DCI-P3, but also produce a color rendering volume of up to 100%, which means that it can restore all colors at any brightness level, exhibiting quantum dots. TV "bright, long, wide" product features.
Summary: The research and breakthroughs in the display technology of the bottom of the knot are all based on the goal of “making people see the effects closer to the real world on the display deviceâ€. The development of quantum dot technology has accelerated this goal. Under the leadership of Samsung, QLED TV will have more opportunities and advantages than OLED, occupying more market share.
