Abstract

The invention discloses a circuit adaptive to different vehicle-mounted remote screens and a vehicle-mounted central control display screen. The circuit comprises a host controller, a serializer and a voltage acquisition module, the voltage acquisition module comprises a single-pole double-throw switch; the movable end of the single-pole double-throw switch is connected with an A / D port of the host controller, the first fixed end of the single-pole double-throw switch is connected with the first direct-current power supply, the second fixed end of the single-pole double-throw switch is connected with the display screen circuit, and the host controller collects the voltage of the A / D port; when the moving end is connected with the first fixed end, the host controller takes the acquired voltage as the reference voltage; when the moving end is connected with the second fixed end, the host controller takes the collected voltage as feedback voltage; and the host controller compares the feedback voltage with the reference voltage to judge the resolution of the display screen. According to the method and the device, the display screens with two resolutions can be automatically adapted, and the personalized customization requirements of customers are met.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a circuit adapted to different vehicle-mounted remote screens and a vehicle-mounted central control display screen. Background technique [0002] With the rapid development of automotive electronics, the use of in-vehicle central control displays on trucks is becoming more and more popular. Due to the limitation of the vehicle model and the installation size of the instrument panel, the central control display usually adopts a split installation design. For example, a central control display includes a host controller and a display. The host controller and the display are connected by high-speed differential signal lines, and different lengths are used according to the needs; while the data communication between the host controller and the display adopts the FPD-Link serializer / deserializer for remote High-speed data transmission and control. At present, there ar...
