TAINAN, Taiwan, Sept. 08, 2026 /CourierPR/ -- Himax Technologies, Inc., a leading supplier of display drivers and other semiconductor products, has unveiled a new automotive TDDI (Touch and Display Driver Integration) solution with high-speed eDP interface support. The HX83196/HX83197 series addresses the demands of next-generation smart car displays, offering large-format, high-resolution, and responsive touch performance.
The new eDP TDDI integrates a high-speed eDP interface, touch, and display driver into a single chip. It features the latest eSRE (eDP Stream Regeneration Engine) technology, which allows direct reception and transmission of high-bandwidth eDP signals. This design supports cascaded configurations, enabling customers to adopt either a single-chip or two-chip architecture based on their panel size and resolution requirements.
The HX83197 model further incorporates Himax’s local dimming technology, enhancing contrast and detail in both bright and dark areas. This technology eliminates the need for an additional Tcon, improving the overall cost efficiency of the solution. Currently, multiple panel makers are in the design-in stage with the new eDP TDDI, and the product will be showcased at the upcoming SID Vehicle Displays and Interfaces Symposium in Detroit, U.S.
According to Ming-Cheng Chiu, Executive Vice President of the Touch and Display Business Unit at Himax, the company has been deeply engaged in the automotive display IC market for nearly two decades. "As the market trends toward larger, higher-resolution displays and increasingly diverse display configurations in smart car interiors, we continue to develop and introduce innovative technologies and products to give customers more options tailored to their needs," Chiu stated.
The new eDP TDDI offers several advanced capabilities, including flexible cascading for large-format, high-resolution displays. A single eDP TDDI can support displays up to 17 inches with 3K resolution, while a two-chip cascaded configuration can support displays up to 30 inches with 6K resolution. Additionally, the automotive display system can cascade two eDP TDDIs with only one eDP output interface, simplifying the design and reducing costs.
Himax’s solution also supports high-resolution touch displays with smooth visual performance, featuring 2,560 source channels and 1,280 touch channels. This configuration enables refresh rates of 60Hz and 90Hz, making it suitable for large-format, high-resolution touch displays. The high integration of the eDP 1.2 interface eliminates the need for an eDP-to-OLDI bridge IC, simplifying the system architecture and reducing costs.
The new eDP TDDI incorporates eDP 1.4 DSC (Display Stream Compression) technology to reduce bit rate and power consumption, mitigating electromagnetic interference (EMI). It also supports HDR10+ for enhanced contrast and detail across bright and dark areas, providing more natural and refined image quality. Furthermore, the ALS-on-Panel architecture supports an interface for an on-panel Ambient Light Sensor, allowing the ALS to be placed directly on the panel without occupying display bezel space, leading to a cleaner and more streamlined display design.
Himax Technologies, Inc., with its comprehensive automotive display IC portfolio, is well-positioned to support the growing demand for advanced automotive displays. The company’s commitment to innovation and customer needs is evident in the development of the HX83196/HX83197 series, which will play a significant role in the evolving automotive display landscape.
