Abstract: With the continuous development of vehicle intelligence and networking, instrument as the most important display and interaction platform for the commercial vehicles, the demand for the human-computer interaction experience and personalized display is becoming more and more urgent. Therefore, more modern and intelligent full liquid crystal display(LCD) instrument have been widely used as the development direction of commercial vehicle instruments in the future. Based on the NXP IMX6-ULL core board, CANalyst-II analyzer, Linux operating system, QT-Creater software, etc., after system transplantation and program design, this paper proposes a set of commercial vehicle full LCD instrument development and design solutions. This solution is easy to maintain and upgrade the system, enhance the sense of space technology and grade of the vehicle, and can better improve the user's personalization and interactive experience.
