Seiko Epson Corporation (TSE: 6724, "Epson") has begun shipping samples of the S2D13V43, a controller IC for high-resolution head-up displays (HUDs). This product features Epson's first-ever implementation of Local Dimming¹ and helps enable the development of HUD systems that offer high resolution, excellent visibility, and low power consumption.

Automotive head-up displays (HUDs), which project speed, navigation, and other essential driving information directly onto the windshield, allow drivers to intuitively access data with minimal eye movement. Vehicles equipped with HUDs are increasingly being adopted, particularly in overseas markets, due to their potential to enhance driving safety and reduce driver fatigue. Demand for HUDs is expected to continue growing. As AR-HUD² systems expand the range of displayed information, the need for higher-resolution HUDs is increasing. However, this trend also presents challenges in maintaining visibility and minimizing power consumption. To address these demands and challenges, Epson developed the S2D13V43, a controller IC designed specifically for high-resolution HUD applications.

The S2D13V43 supports 2K video data streamed from a host SoC³ and performs warping correction to match the curvature of vehicle windshields without requiring external memory. With Local Dimming, the IC analyzes image content and adjusts the backlight accordingly, improving visibility and reducing power consumption in HUDs and other in-vehicle displays. In addition, like Epson's existing HUD controller ICs, the S2D13V43 includes pitch correction and display safety features, helping to build more reliable HUD systems. The product complies with the AEC-Q100⁴ standard and operates at temperatures up to 105℃, meeting stringent automotive quality requirements. It is also planned to comply with ISO 26262⁵ ASIL-B⁶.

Epson seeks to leverage its device technologies to realize a smart society. The company enables its customers to enhance the performance of their products by offering a range of dedicated controller and driver products, including the S2D13V43, for automotive display systems that require high resolution and advanced safety features.

• ¹ A technology that enhances image contrast by selectively controlling the backlight of an LCD display.
• ² An automotive head-up display (HUD) that utilizes augmented reality (AR) technology to overlay essential driving information—such as directional navigation arrows, road signs, and warnings—onto the real-world view seen through the windshield.
• ³ SoC stands for "system on a chip," a type of semiconductor device that integrates many or all the functions required to operate a system onto a single chip. Typical SoCs combine components such as a CPU, memory, and I/O interfaces.
• ⁴ AEC-Q100: AEC stands for the Automotive Electronics Council, an industry organization established by major U.S. automobile manufacturers and leading electronic component suppliers to standardize reliability and qualification criteria for automotive electronic components. AEC standards are widely used as the benchmark for automotive components and have effectively become the de facto industry standard.
• ⁵ An international standard for functional safety that applies to products incorporating electrical and electronic systems in automobiles.
• ⁶ A framework within ISO 26262 for quantitatively evaluating and classifying the stringency of safety requirements.

• Supports resolutions up to 2K at 60 frames per second (fps)
• Corrects images for HUD displays with warping correction so that images match the curvature of the windshield
• Supports pitch correction to stabilize the display position of AR-HUD content in response to vehicle body movement during driving
• Enhances image contrast and reduces power consumption through Local Dimming
• Expected to be compliant with ISO 26262 ASIL-B
• Offers comprehensive display safety features for enhanced reliability in automotive applications
