panels, the demand for display controllers with high processing power and energy effi ciency is skyrocketing. OLEDs alone now make up 50 per cent of the smartphone market, but doesn’t stop there. T e growth of smart home ecosystems, IoT-connected screens and fl exible displays is opening up exciting new opportunities. In fact, by the end of 2023, a staggering 16.6 billion IoT devices were connected fueling even more demand for advanced display controllers. T e future is looking bright and interconnected. Leading semiconductor companies are innovating with AI-cased
display controllers, integrating advanced features such as adaptive refresh rates, variable brightness and AI-enhanced upscaling to improve user experience and power management. For instance, in November 2024, Siemens launched new Industrial PCs with NVIDIA’s GPUs, enhancing AI capabilities, marking a milestone in their 2022 partnership. In terms of region, the Asia Pacifi c dominates the display controller
Industry, driven by the strong presence of display panel manufacturers like Samsung, LG Display and BOE, alongside rising consumer electronics demand in China, Japan and South Korea. North America is witnessing growth in gaming monitors, AR/VR devices, and automotive displays, particularly in the U.S. Europe sees demand from the automotive industry, with luxury car brands integrating advanced digital cockpits. Meanwhile, Latin America and the Middle East are experiencing rising adoption of smart TVs and digital signage, contributing to global market expansion.
Trends oscillating the display controller industry • AI-Enhanced Display Controllers: AI-driven controllers are optimising colour calibration, image scaling and power effi ciency in real-time. Renesas RA8D1 microcontroller group, featuring the Arm Cortex M85 processor, enhances AI-driven display controllers with high performance, optimised memory and graphics, supporting
applications in building automation, smart homes, medical devices and more.
• Adaptive refresh rate & low-power displays: LTPO technology is a game-changer. By adjusting the refresh rate between 1 to 120 HZ based on screen content, it boosts battery life in smartphones and wearables. T is dynamic refresh rate is making devices smarter and more energy-effi cient.
• Integration with automotive ADAS: Advanced Driver Assistance Systems (ADAS) rely on high-performance displays and real- time visualisation, increasing the demand for automotive-grade display controllers. For instance, in January 2025, LG Electronics & Qualcomm’s Snapdragon Ride! Flex Soc launched a cross-domain controller platform, integrating IVI and ADAS, revolutionising vehicle performance and enhancing the driving experience with advanced display controller technology.
• Flexible & transparent displays: T e rise of foldable smartphones and transparent displays in commercial applications is pushing controller innovations. In 2023, there were around 1.2 billion smartphone devices shipped globally, and slightly more than 18 million foldable smartphone units shipped.
The evolving role of display controllers In the end it is clear, that the display controller Industry is evolving rapidly, driven by advancements in display technology across multiple industries. While consumer electronics remain the primary growth driver, sector such as automotive, healthcare, gaming and industrial applications are expanding the market’s scope. Regional manufacturing hubs in Asia-Pacifi c continue to dominate, while AI-powered innovations and adaptive refresh rate technologies are shaping the next generation of display controllers. As display controllers will only become more crucial in delivering high-quality visual experiences.
