Green is the foundation of high-quality development. In recent years, China has actively implemented the concept of "ecological priority and green development," striving to promote the formation of green and low-carbon production and lifestyles throughout society. As a leading enterprise in the display field, HKC has always adhered to the path of sustainable development, empowered the semiconductor display industry system with technology, and continuously improved efficiency for green, low-carbon, and high-quality development.
The industrial sector has always been a major battlefield for energy consumption and a key area for energy conservation and reduction. Through technological innovation, HKC has implemented technological transformations in high-energy-consuming areas and actively explored new models for industrial development.
In terms of display technology, color filters, as a key component for achieving colorization in liquid crystal displays (LCDs), are widely used in TFT-LCD panels.
During the production process of color filters, there is a crucial hard-baking equipment process. The exhaust gas produced by traditional hard-baking equipment during high-temperature operation is often directly discharged into the plant through the hot exhaust pipeline, resulting in a significant loss of thermal energy that fails to be effectively recovered and utilized. Therefore, HKC has successfully achieved the recycling and reuse of thermal energy through thermal cycling modifications to this hard-baking equipment. After repeated debugging and optimization, the power consumption of the heater in a single hard-baking equipment has been reduced by more than 30%, and the annual electricity savings per line exceeds 500,000 kWh.
In addition, HKC has achieved energy-saving breakthroughs in key technological processes.
In the field of liquid crystal displays, photoalignment technology is widely used to control the alignment of liquid crystal molecules, and ultraviolet (UV) lamps are one of the essential tools for this technology, helping to achieve orderly arrangements of liquid crystal molecules.
However, traditional UV lamps consume a lot of energy and generate a lot of heat during use, requiring a large amount of water circulation and having a short service life, which does not conform to the current concept of sustainable development.
Therefore, HKC innovatively proposed the "HKC FSA Green lamp" energy-saving technology. After multiple tests, all verification plans have been completed and mass production has been introduced. The actual annual electricity savings exceed 3 million kWh, with a power saving rate of over 90%. The annual water savings exceed 300,000 cubic meters, with a water saving rate of over 80%.
Not only has HKC achieved energy-saving transformations in technological processes and production equipment, but it has also carried out energy-saving and emission reduction actions and plans from multiple aspects such as energy management, equipment upgrades, and green supply chain management.
Green transformation and energy conservation are our top priorities. As an industry leader, HKC is deeply aware of the importance of green, low-carbon, and sustainable development. In the future, HKC will continue to increase innovation in green production methods and corporate operations, establish and improve an economic system for green, low-carbon, and circular development, and solidify the green foundation for high-quality industrial development.
