Amidst the global display industry's accelerated shift towards green and low-carbon transformation, HKC has successfully broken through the industry's dilemma of reconciling high contrast ratios with sustainable development in LCD panels through its independently developed CR2400 technology, providing an innovative paradigm for the green upgrading of the display industry.
Technical Definition and Industry Challenges of High Contrast Ratio
The contrast ratio (CR) is a core metric for measuring the optical performance of display devices, defined as the ratio of the screen's maximum brightness (white) to its minimum brightness (black). For instance, a CR of 2400:1 means that the brightness of the white area is 2400 times that of the black area. A higher contrast ratio signifies superior representation of light and dark shades and details in dark scenes, which is particularly crucial in HDR imaging, professional design, and immersive gaming scenarios.
Currently, traditional LCD technologies rely on the Photo Alignment process to enhance contrast ratios, but this technology faces three major bottlenecks:
Import Dependency: The need to procure high-priced photosensitive materials and precision UV exposure equipment.
High Energy Consumption: UV lamps account for 15% to 20% of the total energy consumption in panel production, with short lifespans and high maintenance costs.
Environmental Risks: UV lamps contain mercury, which can cause soil and water pollution if not disposed of properly.
Three Innovative Breakthroughs of HKC's CR2400 Technology
Technological Path Innovation:
By optimizing the Rubbing Alignment process, HKC has addressed the issue of dark-state light leakage, elevating the static contrast ratio to 2400:1, reaching an industry-leading level for LCD panels.
HKC has become the world's first display panel enterprise to achieve a CR of 2400 through Rubbing Alignment, breaking the performance monopoly of the Photo Alignment technology.
Cost and Energy Efficiency Advantages:
30% Cost Reduction: Eliminating the need for imported materials and equipment in the Photo Alignment process, enabling localization of the supply chain.
50% Energy Consumption Reduction: Saving 2kW·h of electricity per panel produced, reducing energy consumption per unit of output by 50% compared to traditional processes, far exceeding the energy efficiency improvement targets set out in the "Action Plan for Carbon Peaking Before 2030" for the electronics manufacturing industry.
Pollution Prevention and Control: Avoiding the mercury pollution risks associated with UV lamps and reducing the environmental footprint of the production process.
Large-scale Carbon Reduction Benefits:
A single production line can reduce annual carbon emissions by 800 tons (equivalent to the annual emissions of 300 gasoline-powered passenger cars), marking a benchmark breakthrough in China's display industry's implementation of the "carbon peaking and carbon neutrality" strategy.
Driven by technological innovation, HKC is painting a new picture of green displays. Guided by the "dual carbon" strategy, the HKC CR2400 technology not only redefines the cost-effectiveness limits of high contrast ratio technologies in LCD panels but also pioneers a new industrial paradigm of "high performance + low carbonization" development. This innovation, rooted in China's manufacturing DNA, is providing a "Chinese solution" for the green transformation of the global display industry—ensuring that every screen that lights up pays homage to a beautiful ecosystem. In the future, HKC will continue to deepen technological iterations and collaborate with industry chain partners to jointly stride towards a new era of "zero-carbon displays"!
