Description

Technical Field

[0001] This utility model belongs to the field of vehicle equipment, and specifically relates to a liquid crystal instrument module for original vehicle retrofitting. Background Technology

[0002] Throughout the development of the automotive industry, the instrument panel, as a core component for displaying vehicle information, has undergone several technological iterations. Traditional automotive instruments primarily employ a mechanical structure, displaying basic information such as vehicle speed, engine speed, fuel level, and coolant temperature through physical pointers, dials, and simple indicator lights. While these instruments offer advantages such as high reliability and low cost, they also suffer from the following inherent drawbacks:

[0003] 1. Limited information display: Mechanical instruments can only provide limited fixed information, such as vehicle speed and RPM, and cannot be expanded to display the diverse data required by modern vehicles, such as navigation, tire pressure monitoring, and driver assistance.

[0004] 2. Poor interactive experience: The response speed of mechanical pointers is limited by physical inertia, resulting in a delay, which makes the data information observed by the driver lagging behind.

[0005] 3. Difficulty in expanding functionality: The functions of mechanical instruments are fixed, and it is impossible to add new functions through software upgrades, such as ADAS alarms and energy consumption analysis.

[0006] With the development of automotive intelligence, smart products are being applied to more and more cars. Upgrading traditional mechanical dashboards to LCD dashboards is one of the trends in the intelligentization of traditional cars. How to realize this is one of the problems that existing technologies urgently need to solve. Utility Model Content
