In today's wave of automotive intelligence, the in-vehicle display screen, as a crucial window for human-machine interaction, plays a pivotal role in the driver's experience and safety. Before entering the automotive sector, companies must pass stringent automotive specification standards and the IATF 16949 quality management system. Furthermore, automotive display screens adhere to standards that surpass those of industries such as industrial and consumer electronics.
As a leader in the display field, HKC has responded to industry standards and market demands by introducing a 12.3-inch automotive central control display that combines high contrast, wide color gamut, and excellent transparency. This display aims to enhance the driving experience and meet the needs of human-machine interaction.
Firstly, considering the complex and variable environments that vehicles encounter during operation, such as extreme temperatures, humidity, vibrations, and dust, in-vehicle display screens must possess exceptional stability and reliability to ensure seamless operation under adverse conditions. HKC's 12.3-inch central control display excels in surface temperature rise, screen response time across different environments, and RA (Reliability Assessment) reliability, surpassing industry benchmarks.
Surface Temperature Rise
To address screen heating, HKC employs an advanced Cu process technology that enhances screen performance while reducing heat generation in circuitry, resulting in energy savings. Additionally, this 12.3-inch display boasts superior light transmittance of 4.2%, allowing for optimized backlight current and further energy reduction. Consequently, whether operating at low (801 nits) or high (1165 nits) white-state brightness, the maximum temperature rise at five points does not exceed 11°C and 13.2°C respectively, surpassing the industry standard of 15°C for automotive displays. This design not only prolongs device lifespan but also enhances user experience.
Response Time
In terms of response time, HKC's 12.3-inch central control display meets the strictest industry standards for automotive applications—European regulations. It ensures smooth and rapid display transitions in various demanding driving environments.
European Regulations for Automotive Displays:
Ta = 25°C, ≤20ms: Black-to-white response time does not exceed 20 milliseconds at an ambient temperature of 25°C (similarly for other temperatures).
Ts = 25°C, ≤22ms: Response time does not exceed 22 milliseconds when the display surface temperature is 25°C (similarly for other temperatures).
High RA Reliability
HKC adheres to a customer-oriented approach, designing and developing highly reliable automotive materials based on client specifications. These materials undergo rigorous testing before being incorporated into automotive products. Currently, the 12.3-inch central control display meets the RA specifications for pre-installed automotive applications.
Contrast and Color
To maintain optimal image quality under varying light conditions, HKC invests heavily in contrast and color technology. The industry standard for contrast ratio is typically 1100:1 with an average of 1500:1, which HKC exceeds through advanced pixel design and high-contrast materials, achieving a minimum contrast ratio of 1200:1 and an average of 1500:1.
In color development, HKC has successfully covered a wide range of color gamuts by optimizing materials within the color filter, liquid crystal cell, and backlight systems. The 12.3-inch display can achieve 75% NTSC with standard backlight and 85% NTSC with KSF backlight.
Customization and Production Capacity
Given the in-vehicle display's application within the automotive interior, customization and personalization are essential. HKC boasts multiple high-generation production lines and robust manufacturing capabilities. Its core MMG nested cutting technology meets individual needs while reducing production costs, providing personalized, cost-effective display solutions that cater to diverse vehicle models and markets.
Currently, HKC's 12.3-inch central control display is in mass production for multiple domestic automotive manufacturers, establishing itself as a standard product. With significant investments in automotive display R&D, years of display technology expertise, and close collaboration with automotive clients, HKC continues to expand its automotive display panel technology, bridging the gap from domestic to international markets with steadily growing market share. Looking ahead, HKC remains committed to the automotive display sector, driven by innovation, to deliver even more superior and intelligent display solutions to its customers.
