Himax Begins Mass Production of Advanced In-Cell Touch Tech for AI Laptops

Himax Technologies, Inc. (NASDAQ:HIMX), an industry leader in fabless display driver ICs and other semiconductors, today announced the successful mass production of its cutting-edge In-Cell Touch TDDI (Touch and Display Driver Integration) solution, the HX83132, for high-end LCD AI laptops. The HX83132 has already been adopted by several leading panel makers across the board. By entering mass production during the third quarter of 2024, this marks a significant milestone for the first-of-its-kind, innovative product. As notebook brand customers increasingly prioritize product differentiation and value enhancement, the integration of touch functionality into displays of high-end laptops and AI PCs has emerged as a key trend. Himax HX83132 is featured in one marquee brand's first AI laptops, which boasts a 15.3-inch, 2.8K high-resolution touch display with a 120Hz refresh rate, significantly enhancing both interactivity and visual experience for seamless, intuitive user operations.

In-cell TDDI has become a mainstream technology for LCD displays, characterized by the seamless integration of touch functionality with display driver ICs. This integration not only simplifies the supply chain but also provides substantial cost benefits to panel manufacturers. Having pioneered the mass production of In-cell TDDI technology for mid-sized tablets and automotive displays in 2019, Himax has established itself as the industry leader by introducing an industry-first touch display solution supporting screen sizes of up to 45 inches for ultra-large automotive applications. The newly launched HX83132 series further expands the application of In-cell TDDI technology to laptops, boasting a unique design architecture that pairs seamlessly with timing controller (Tcon) chips supporting various eDP specifications which make it suitable for both mainstream and high-end LCD laptops. This TDDI and Tcon configuration effectively minimizes the need for supporting components, resulting in a more compact PCB size and narrower bezel design. The HX83132 series offers precise touch sensitivity, ensuring smooth human-machine interaction, significantly enhancing user experience and improving productivity.

The industry-leading HX83132 In-cell TDDI solution offers the following key features:

• Flexible support for diverse panel sizes and resolutions: The advanced chip architecture can interconnect up to 6 chips, accommodating a wide range of laptop display needs with support for screen sizes up to 16 inches and resolutions up to 4K
  
  
  
   
• Optimized and streamlined module architecture design: The HX83132 solution outperforms competition by providing more display and touch channels at the same resolution while utilizing fewer ICs. Additionally, the integrated microprocessor and level shifter minimize the need for external components, resulting in a smaller PCB size and enhanced design efficiency
  
  
  
   
• Leveraging existing architecture for rapid In-cell Touch upgrades: The HX83132 features a state-of-the-art, integrated proprietary display driver and touch controller architecture. From a display perspective, it utilizes a standard Tcon architecture, which enables pure display panels, without the need for a dedicated Tcon for the In-cell touch functionality. Meanwhile, the TDDI integrates an in-house proprietary distributed touch microprocessor architecture, specifically designed to handle the high computational demands of touch data processing, effectively reducing development time
  
  
  
   
• Comprehensive support for various power-saving operation scenarios: The HX83132 is compatible with eDP 1.4 and eDP 1.5 Tcons, and supports multiple power-saving features, including Panel Self Refresh (PSR) and User-Based Refresh Rate (UBRR), optimizing energy efficiency across different usage scenarios
