With the rapid evolution of intelligent vehicles, the demand for immersive and adaptive cockpit displays is growing faster than ever. Automotive OEMs and Tier-1 suppliers are looking for flexible display configurations that can seamlessly integrate into dashboard designs while providing high visual quality, responsiveness, and reliability.
To meet this trend, Aptus Technology developed a custom splicing display solution composed of two 10.3-inch automotive-grade TFT-LCD modules. This dual-screen integration offers a panoramic and continuous display experience across the cockpit, combining precision engineering with advanced display technologies to deliver a next-generation digital interface for automotive applications.
The concept behind this design was to create a continuous visual surface using two 10.3-inch LTPS TFT-LCD panels, forming a wide aspect-ratio display suitable for dashboard, co-pilot entertainment, or vehicle information control interfaces.
Each display module is based on the APS-C103HAX01.A LCD, originally developed using AUO’s C103HAX01.A cell, integrating AHVA (Advanced Hyper-Viewing Angle) technology and in-cell touch structure with TDDI (Touch and Display Driver Integration).
By aligning two panels with precise mechanical tolerances and synchronized signal timing, Aptus engineers successfully built a dual-module spliced display capable of delivering consistent image performance across both panels, ensuring a visually unified user experience even under wide viewing conditions.

The combination of AHVA wide-view technology and in-cell touch allows for a thinner assembly, improved optical clarity, and reduced reflection — critical for vehicle environments where both sunlight readability and design compactness are essential.
Developing a spliced automotive display from two separate LCD modules required multiple engineering considerations.
Seamless Alignment: The two 10.3-inch panels must align perfectly within ±0.1 mm mechanical tolerance to ensure continuous visual flow without visible seam gaps or luminance inconsistency.
Signal Synchronization: Both displays are driven through synchronized LVDS signals with carefully matched timing conditions to eliminate frame delay and color misalignment.
Thermal Management: Given the narrow bezel and high brightness requirement, custom thermal dissipation materials were applied to maintain performance under extended temperature cycles.
Electromagnetic Compatibility (EMC): Additional EMI suppression and grounding optimization were conducted to ensure the design meets CISPR 25 Class 3 standards.
Touch Performance Calibration: In-cell capacitive sensors were tuned for uniform response across both modules, ensuring that gestures and touch recognition feel natural even at the splicing boundary.
Through precise calibration, the final assembly achieves uniform brightness, accurate color reproduction, and reliable touch control — comparable to a single continuous display.
The dual 10.3-inch module solution delivers superior display performance suited for automotive instrument clusters and co-pilot entertainment systems.
High Luminance & Contrast: Up to 1000 nits brightness and 1400:1 contrast for perfect visibility under sunlight.
Wide Viewing Angles: AHVA panel structure ensures consistent color and clarity across all positions.
Fast Response Time: 25 ms at 25 °C for smooth motion graphics.
Anti-Glare Surface: Reduces reflections and improves readability.
Integrated Touch Control: In-cell design eliminates extra layers, reducing weight and enhancing vibration resistance.
To meet automotive quality standards, the module underwent extensive reliability testing under Aptus and AUO protocols.
High-Temperature Operation: 85 °C / 500 hours
Low-Temperature Operation: -30 °C / 500 hours
Thermal Shock: -40 °C ~ 85 °C / 200 cycles
High Humidity: 60 °C, 90% RH / 500 hours
Vibration & Shock: compliant with JIS D1601 and IEC 60068-2-27
ESD Immunity: ±8 kV air, ±6 kV contact
These evaluations confirm the module’s long-term stability, durability, and performance in demanding automotive environments.
Aptus provided full engineering support from concept to production, including custom dual-LVDS control boards, firmware synchronization, and thermal optimization.
Mechanical fixtures ensured precise alignment, while firmware tuning balanced brightness, color uniformity, and touch calibration. The result is a cohesive system behaving as a single wide display with perfect synchronization.
This integrated approach simplifies dashboard implementation and minimizes additional engineering for automotive OEMs.
The dual 10.3-inch spliced display delivers a balance of innovation, cost efficiency, and modular scalability. It allows vehicle manufacturers to create a panoramic cockpit display that merges driver and passenger information areas into one continuous visual field.
The modular concept also enhances adaptability across different models and trim levels, enabling OEMs to upgrade design features without re-engineering the entire system.
