To promote the expansion of the quantum dot market, Nanocrystalline Technology has launched the third generation of quantum dot diffusion board products.
As a representative enterprise of domestic quantum dot film, nacrystalline technology will focus on the research and development of quantum dot diffusion plate technology after achieving large-scale mass production of quantum dot film in 2019, and successfully launched the third generation of quantum dot technology products - quantum dot diffusion board QDP N1.0 series at the end of 2021, which will promote the further sinking of quantum dot technology in the display market.
According to Nanocrystalline Technology, QDP uses multi-layer co-extrusion molding to embed quantum dots in the diffusion plate, thereby achieving the effect of light conversion and bringing about a leap in display quality. QDP N1.0 series is equipped with the third generation of water oxygen stabilization quantum dots developed by nanocrystalline innovation, this generation of materials using the latest excited state synthesis technology, supplemented by entropy ligand modification, effectively inhibit the Auger effect, eliminate the defect site, greatly improve the light stability, reduce or even get rid of external protection conditions, such as dependence on the barrier film, which is characterized by strong stability, in the high temperature, high humidity, high light intensity conditions, can work stably for a long time.

The cost advantage helps the quantum dot diffusion board market sink
As the leader of future display technology, quantum dot display technology continues to iterate its product form to meet the growing market demand. From the perspective of supply chain, terminal companies such as TCL, Hisense, Xiaomi, and Huawei actively lay out quantum dot TV products, which also brings development opportunities for upstream quantum dot-related enterprises.
At present, the three major technologies in the field of quantum dot display are quantum dot film, quantum dot diffusion plate and quantum dot lens, of which the quantum dot diffusion plate includes the diffusion layer, the quantum dot layer, and the diffusion layer structure, which is a typical "sandwich structure".

Compared with the quantum dot film, the quantum dot diffusion plate abandons the expensive barrier film, and the cost is greatly reduced, providing the necessary conditions for the sinking of the quantum dot display terminal.
Najing Technology believes: "Taking TV as an example, in the head manufacturers, the proportion of high-end products is basically about 10%, the proportion of low-end products can reach 50%, and a single customer demand can achieve tens of millions of units (flat) scale, and the development of quantum dot diffusion boards can successfully leverage this part of the market." ”
Three generations of quantum dot diffusion plates have been launched, and the first generation has been shipped stably
Najing Technology revealed to the silver film chain that the company's current products on sale include two series of QPH-PS and QPL-PS, which are the company's first generation of quantum dot diffusion plates, which have passed the reliability verification of major brand manufacturers, and many models have been stable and mass-produced -
1. QPH-PS is a high-performance PS product, suitable for higher specification display terminals, such as quantum dot color conversion technology combined with the global dynamic backlight of MiniLED technology, which can achieve perfect contrast and accurate color performance;
2, QPL-PS for excellent performance PS products, suitable for mid-range product positioning, such as combined with high-power / full of stars direct downbacklight, to achieve higher brightness performance and wider color gamut.
At present, QPH-PS and QPL-PS two products have successfully passed the import verification of TCL, Hisense, Huawei, Skyworth, BOE, Guanjie, Changhong, QPH-PS in the project of Guanjie, Changhong batch stable shipment, QPL-PS in Changhong, Qi Yue, MMS project batch stable shipment, is expected in the second quarter of 2022 in TCL, Hisense, Guanjie products will also be bulk shipments.
In addition, nanocrystalline technology's second-generation QD PS foam board, which integrates the latest diffusion plate technology and quantum dot technology, effectively eliminates light shadows and improves color gamut, which will play a positive role in reducing costs in terms of the comprehensive cost of products. Najing Technology said that the product has entered the eve of mass production and is expected to be introduced to the market in the second half of 2022.
The third generation of QD PS composite board, its advantages are mainly reflected in multi-functional composite, simple assembly and effective reduction of assembly labor costs of the whole machine production line, etc., is expected to be mass production in the second half of 2023.
"It is expected that in the NEXT three years in the TV market, the demand for QDP for quantum dot diffusion boards will increase explosively." Nanocrystalline Technology revealed in the interview. "The quantum dot diffusion board will cooperate with TV terminals to continuously expand the market penetration rate of quantum dot displays, and it is expected to gradually cut into the mid-end or even low-end TV market on a large scale."
Why choose PS System?

In terms of process, the quantum dot diffusion board on the market is mainly divided into two major systems: PMMA and PS. The quantum dot diffusion plate that appeared in the early days was mainly based on the PMMA system, which had good adaptability to quantum dots and good oxygen resistance, but the PMMA material cost was high and it was easy to absorb moisture and deform.
"The raw material price difference between PS and PMMA is nearly double, especially at the moment when the global chemical raw materials are rising, the main ingredient of the product is made of lower cost materials, which is conducive to the expansion of the market." Nanocrystalline Technology expressed its views on the cost perspective.
Based on this, Nanocrystalline Technology in the early stage of development of the PS system research and development, by improving the tolerance of quantum dot materials to water oxygen and high temperature to achieve the performance of the finished product, the current mass production of PS diffusion board compared to the FRIEND's PMMA material, the reliability is better, especially in the high temperature and high humidity conditions, long-term use of stability is good, the material property characteristics are more suitable for the requirements of medium and large size products, in the cost also has a greater advantage.
In response to the question of "whether quantum dot diffusion plate technology can be combined with other display technologies", Najing Technology said in this interview that the quantum dot diffusion board can compound a variety of functional materials and match the straight down type and MiniLED backlight.
The core of quantum dot diffusion board technology lies in the water oxygen stabilization quantum dots, the third generation of quantum dot materials put into production, can be extended to quantum dot light guide plate, quantum dot LED packaging, quantum dot ultra-thin film and other product forms, the application covers TVs, displays, laptops, tablets, mobile phones and other full-size needs, the applicable backlight almost covers the entire display industry.
At present, nanocrystalline technology's quantum dot masterbatch production capacity can match the demand of 15 million pieces of diffusion board, after the QDP N1.0 series, will continue to develop quantum dot foam board QDP N2.0 series, quantum dot composite board QDP N3.0 series and other more cost-effective and performance advantages of the products, the future will provide customers with more high-quality quantum dot technology solutions.
