The Product Development Department of Pulang Innovation mainly researches and produces semiconductor quantum dot luminescent materials, including alloy quantum dots, quantum rods, nanosheets, quantum dot color enhancement films and display modules. These materials have broad application prospects in fields such as liquid crystal displays, Micro-LED semiconductor displays, flexible displays, semiconductor lighting, photoelectric detection, and solar cells.
Alloy quantum dot material The emission wavelength covers the entire visible light range, with a half-peak width of FWHM ranging from 20 to 30nm. Compared with traditional binary quantum dots, it has excellent optical and thermal stability. Meanwhile, quantum dot inks with different solvents can be customized according to customer requirements, and are applied in inkjet printing, photolithography, electroluminescent devices and other wide color gamut display, photoelectric detection, solar cells and other fields.
Quantum rod materials: The peak emission wavelength is between 620 and 640 nm, with a half-peak width of 25 to 35nm. They possess fluorescence polarization characteristics and have great prospects in low-power display, photoelectric detection and other fields.
Nanosheet materials: By controlling the number of nanosheet layers and the material ratio, their emission wavelengths can be precisely regulated, covering the blue light to green light bands. Nanosheets have an ultra-narrow half-peak width of FWHM<10nm, thus enabling ultra-wide color gamut (>140% NTSC) display.
Quantum dot color enhancement film: Ultra-thin film, with a thickness as low as 100-150μm, suitable for small-sized display modules such as smartphone backlights. It has a wide color gamut (NTSC>100%), effectively enhancing display performance.
Phosphor film is an optical film made from phosphor, barrier resin and optical-grade PET film as the main raw materials, combined with high-precision coating technology, and can be applied to Mini-LED backlight display.
