An in-vehicle display screen mainly consists of the following core components:
Display Panel
Liquid Crystal Display (LCD): Most in-vehicle screens use TFT-LCD technology, displaying images through a backlight. Some high-end models use IPS panels to improve viewing angles.
OLED Screen: Equipped in a few luxury models, its self-emissive nature allows for higher contrast and flexible curved designs.
Touch Layer
Resistive Touch: Operates through pressure sensing, low cost but only supports single-point touch.
Capacitive Touch: The mainstream solution, supporting multi-touch, with a tempered glass surface for enhanced durability.
Driver Module
Timing Controller (TCON): Responsible for parsing video signals and controlling pixel refresh.
Power Management Chip: Provides stable voltage for various components, such as LED backlight drivers.
Housing and Structural Components
Metal/Plastic Frame: Provides mechanical support; some designs include heat sinks.
Anti-Glare Coating: Reduces the impact of sunlight reflection on visibility.
Interfaces and Connectors
LVDS/FPD-Link Interface: Used for transmitting high-definition video signals.
CAN bus interface: Communicates with other vehicle systems (such as the instrument panel).
Auxiliary components: Ambient light sensor: Automatically adjusts brightness based on external light.
Heating element: Prevents screen frost in cold-climate vehicles.
Different models may integrate additional functional modules, such as HUD projection components or fingerprint recognition modules, but the above is a common core structure.
