HKC has innovatively developed the green TED (Transparent Electron Device) technology with high penetration rate, leading the new trend of green and low-carbon displays

For business trips, entertainment, gaming, education, and teaching... With the rapid development of the information age, consumers are increasingly using laptops, and their requirements for laptop screens are also becoming more diversified. HKC innovatively introduced the concept of a green TED high-penetration laptop display screen. By continuously promoting the iterative development of liquid crystal driving technology, it responds to the dual needs of the laptop market and customers, leading the industry towards innovative green development.

  • With the iterative development of liquid crystal driving technology, TED high-penetration technology has significant advantages

In the early stages, liquid crystal driving display technology mainly relied on traditional Single Gate LCD. This technology adopted a single-gate structure, which, to a certain extent, met people's viewing needs, but there was still much room for improvement in terms of image quality, power consumption, and other aspects.

With the advent of DRD (dual-rate driving) technology, liquid crystal display technology achieved a new breakthrough. By controlling dual positive and negative gate electrodes, DRD technology optimized the design of "field-effect transistors" (specialized in controlling pixel drive and changes). Although this design reduced the number of driver chips required for the panel by 2, the aperture ratio decreased by 15% compared to Single Gate. Aperture ratio, as the "light transmittance" of each small window on the liquid crystal screen, is crucial to screen brightness and color vividness. A higher aperture ratio allows light to pass through these small windows more easily, making the screen appear brighter and more vivid. Therefore, DRD technology requires the use of high-brightness backlight sources to achieve high brightness, and this design architecture is obviously inconsistent with the concept of green energy conservation.

To further improve the image quality and energy-saving performance of liquid crystal screens, TED driving technology emerged. TED technology integrates the timing controller (responsible for controlling the time and sequence of screen signal display) and the driver integrated circuit (ensuring that the liquid crystal screen can work normally and display content), simplifying the circuit structure of the display system. While reducing manufacturing costs, it also reduces loss and interference during signal transmission, thereby improving system stability and reliability. At the same time, TED technology adopts an efficient energy management strategy, achieving higher energy utilization efficiency by optimizing power supply design and reducing power consumption. This achieves the goal of energy conservation and environmental protection, further reduces operating costs, and aligns with the green development trend of modern society.


Innovation and upgrade, transcending new horizons: HKC's green TED high-penetration technology

Following industry trends, HKC absorbed the essence of TED driving technology, innovatively introduced the concept of green TED high-penetration products, and further formed technological research and development for application on HKC laptop display screens.

Using HKC's green TED high-penetration technology, the aperture ratio of the laptop display screen is increased by 35% compared to ordinary DRD technology, achieving a penetration rate of up to 9.05%, reaching the industry's first-class level. This means that under the same display area, HKC's laptop display screen can more effectively utilize light, making the picture brighter and clearer. While maintaining the same product brightness, the backlight energy consumption of this display screen is reduced by 35%, effectively improving the product's energy efficiency ratio, further enhancing HKC's sustainable development.

To further optimize the performance of the laptop display screen, HKC also adopted dual-copper process technology, achieving low signal delay while maintaining ultra-high penetration. Power consumption was reduced by over 20% year-on-year, effectively reducing energy consumption and CO2 emissions, making it more environmentally friendly and energy-saving. Moreover, the display screen uses a small number of IC chips, further saving overall costs. This display screen has now passed the client's reliability condition verification and is about to enter the new product development and production phase.

Therefore, HKC's TED green high-penetration technology not only achieves excellent performance in high penetration and low power consumption, but also ensures effective cost control, satisfying customers' multiple needs in terms of performance, energy conservation, and cost.

In an era where high quality and sustainable development coexist, HKC's innovative green TED high-penetration technology will empower more high-end products, providing consumers with clearer and more vivid visual effects while promoting the green and low-carbon development of the industry.
