Vehicle-mounted display control system and method, terminal and vehicle

Abstract

The invention discloses a vehicle-mounted display control system. The vehicle-mounted display control system comprises a display controller and a serializer, the serializer comprises at least two voltage-controlled oscillators and is used for providing corresponding voltage-controlled voltages for the selected voltage-controlled oscillators according to a preset reference frequency, so that the selected voltage-controlled oscillators work at corresponding normal working frequencies according to the voltage-controlled voltages; the working frequency ranges of the at least two voltage-controlledoscillators at the same temperature are different from each other; a display controller which is used for selecting a corresponding voltage control oscillator for the serializer according to the obtained current environment temperature of the environment where the vehicle is located; wherein the working frequency range of the currently selected voltage-controlled oscillator at the current temperature comprises the reference frequency. The invention further discloses a vehicle-mounted display control method, a terminal and a vehicle. By adopting the system of the invention, the abnormal display problem of the vehicle-mounted display terminal can be avoided by optimizing the control strategy in the environment temperature change process.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a vehicle display control system, method, terminal and vehicle. Background technique [0002] With the rapid development of in-vehicle technology, in-vehicle terminal products have stricter requirements on operating temperature, generally requiring them to work normally between -30°C and 75°C. At present, there are two solutions for the existing car navigation products: one is the all-in-one solution where the host and the display are integrated, and the host transmits RGB video signals to the display for direct display through the cable; the other is the host and the display In the separated split machine solution, the video signal of the host computer is transmitted to the display screen through the LVDS cable for video display, specifically: the display master chip sends the video signal to the serializer for corresponding processing, and the serializer will process t...

AI Technical Summary

Problems solved by technology

The existing method of regularly detecting the serializer or deserializer will have a certain delay and cannot solve the problem of abnormal display of the vehicle-mounted display terminal in time

Moreover, during the reset process of the serializer or deserializer, the display screen will flicker for a moment, and then return to normal, which is not a good user experience
