At present quantum dots QLEDs and OLEDs are regarded as secret weapons by color TV manufacturers. They are all launched at the launch of flagship models. OLEDs have a long development time. They are limited to technical rigor, and production capacity is reserved. QLEDs are in picture quality, color performance and price. There is a good balance between them, which leads to a very high cost-effective choice. So what's the QD display technology?
What is a quantum dot?
The world No. 8 chemist Professor Peng Xiaogang once summed up in this way: Quantum dots may be the best luminous material that humans have ever discovered.
2 How do quantum dots shine?
By changing the quantum dot size, continuously adjustable, it can achieve from blue to green, to yellow, to orange, to red emission, accurate and pure color.
3 quantum dot color gamut effect?
According to the highest BT.2020 standard, quantum dots can achieve 100% color gamut, restoring all the colors we can perceive.
4 Quantum dot processing
Quantum dots are processed through the unique 'green' solution process. Compared to vacuum evaporation of OLEDs, quantum dots have five major advantages:
1, The cost of the product line is low;
2, The energy consumption is very low, reaching 1/5, 1/10 of the OLED process;
3, The use of raw materials is high, and the environmental pollution is small;
4, through non-contact production mode;
5, high pass rate.
5 contains 'cadmium' problem
The quantum content of a quantum dot TV is less than that of everybody eating three days of rice, and the damage to the human body is minimal.
6 First Generation Quantum Dot Displays: Photoluminescence
The QD TVs we currently buy are based on the first generation of photoluminescence technology and achieve a larger color gamut and a more stable display effect through inorganic material quantum dot backlights.
7 Second Generation Quantum Dots Display: Electroluminescence
The second-generation quantum dot display adopts the principle of self-luminescence. It customizes electroluminescent display quantum dots for QLEDs and displays them by electroluminescence. It is also a quantum dot. The electroluminescence is much better, and it is not limited by the color filter. much better.
