Quantum Dot Film's Advantages And Future Development Trends

What is a quantum dot film?

Quantum dot film is a wide color gamut special optical film made with quantum dots, barrier resin and optical grade water and oxygen barrier film as the main raw materials, combined with high-precision coating technology.

Different from the traditional liquid crystal display, the quantum dot display uses blue LED as the light source. The quantum dot film will excite pure green and red light under the excitation of blue light, and then mix the blue light to form high-quality white light. This special nano The technology realizes the high color gamut coverage of the display and restores the colors.

Advantages of quantum dot sheet:

The advantages of quantum dot sheet can be summarized as: high, pure, and stable in three aspects

High: The color gamut is high. Under the NTSC standard, the color gamut of ordinary LED TVs is only 72%, the first-generation high-color gamut TVs are only 82%, and the OLED display can reach 100%, while the color gamut coverage of quantum dot TVs is as high as 110%;

Pure: the color is pure, the color purity is more than 50% higher than that of ordinary LED, and the natural color is accurately presented;

Stability: It means that the performance is stable, the life of the film is long, and the quantum dots of stable inorganic nanomaterials can ensure that the color will not fade for a long time.

The above is the introduction of quantum film and its advantages.

There will be three major trends for quantum dots to rebound in the future:

◤ Trend 1: Quantum Dot Brightening Composite Film

The performance of the quantum dot brightness enhancement composite film is equivalent to the composite effect of the conventional quantum dot film and the brightness enhancement film, which can improve the yield of the backlight module.

◤ Trend 2: Cadmium-free quantum dot film

At present, quantum dot diaphragms are divided into two types: cadmium-containing and cadmium-free.

The EU ROHS standards and domestic regulations have issued regulations restricting the use of toxic and hazardous substances such as lead and cadmium in electronic products. The market pursues environmental protection, and the application of cadmium-free quantum dots will rapidly increase.

At present, RINA TECH quantum dot film has a cadmium-free film that is fully compliant with EU ROHS, which is widely used in LCD TV. We are committed to solving TV backlight solutions to achieve high brightness and high color gamut.

◤ Trend 3: Quantum Dot Color Film

Quantum dots are added to the color film to realize the transition from the color filter layer to the light-emitting layer. The realization of quantum dot color film technology can greatly improve the performance of quantum dot display in color gamut, color viewing angle and brightness.

However, there are also many technical difficulties in the manufacturing process of quantum dot color films, such as:

·High temperature preparation process reduces luminous efficiency

· The polarizer sheet needs to be built-in to ensure the polarization state of the excitation light

·Quantum dot material packaging problem

Among the three major trends, cadmium-free quantum dot films have been recognized by many domestic companies.

In general, the development of quantum dot technology will promote the development of science and technology, and will also create a better color TV world for us.

RINA TECH quantum dot display technology, as the most cost-effective wide color gamut display solution, is being recognized by more and more brand manufacturers and consumers.
