It is reported that in the field of displays, the most widely used color gamut standard is BT.2020. The standard was formulated by the International Telecommunication Union (ITU) for ultra-high definition displays, covering about 75% of the visible spectrum of the human eye. It is currently the industry standard with the widest color gamut, with a color gamut range far exceeding the common DCI-P3 (approximately 50% BT.2020) and sRGB (approximately 35% BT.2020). According to reports, HKC Huike has increased the "purity" of red and green light by 40% by developing a high-purity color filter film, making the red more fuller and the greener brighter, and expanding the color gamut range of the product to 94% of the BT.2020 standard. In addition, this technology also realizes parameters such as 350nit brightness and 1500:1 high contrast, making the product screen clearer in sunlight and more delicate in dark light; through low blue light C2 certification, the harmful blue light peak is moved from 450nm to 460nm, reducing stimulation to the retina, making it less fatigued for a long time, allowing both eye protection and image quality. As a future trend, HKC Huike BT. 2020 has reached a level of 94%, which means it is close to the current technology ceiling and will bring customers a more extreme color experience. As a part of the display ecosystem, HKC Huike laptop screens have been widely used in product lines of major brands such as HP, Dell, Lenovo, Acer, etc.
