Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automobile parts, in particular to a vehicle-mounted instrument panel capable of self-adapting to ambient light brightness. BACKGROUND

[0002] A vehicle-mounted liquid crystal instrument panel (also known as a digital instrument panel or a liquid crystal display instrument panel) is an electronic display system used to display vehicle information in modern vehicles. It replaces traditional analog instruments (such as a needle-type speedometer, a tachometer, an oil gauge, etc.) and uses a liquid crystal display screen (LCD or OLED, etc.) to provide various information required by the driver. The vehicle-mounted liquid crystal instrument panel is usually integrated on the instrument panel and can provide more intuitive, customizable and dynamic display effects.

[0003] The vehicle-mounted instrument panel capable of self-adapting to ambient light brightness is a technology that automatically adjusts the brightness of the instrument panel to adapt to the intensity of external ambient light. By equipping one or more ambient light sensors on the vehicle-mounted instrument panel, the light changes inside and outside the vehicle can be monitored in real time. These sensors perceive the intensity of external light or changes in light inside the vehicle and transmit data to the control system of the instrument panel. According to the information provided by the sensors, the control system automatically adjusts the brightness of the display screen of the instrument panel.

[0004] Although the self-adaptive adjustment of the brightness of the display screen of the instrument panel can be achieved, the vehicle-mounted instrument panel is usually made of plastic or composite materials. These materials will expand or shrink when the temperature changes, causing the components of the vehicle-mounted instrument panel to deform slightly when the temperature changes. This deformation can also cause loosening or poor contact, so that temperature changes can cause friction between the components of the vehicle-mounted instrument panel and thus produce abnormal noise.
