Problems solved by technology
However, due to the sensitivity of human vision to brightness changes, drivers and passengers can clearly feel the difference in display brightness when switching between different displays, and the user experience is not good.
[0007] Under the external ambient light conditions of some special scenes, each display shows different display brightness states due to the ambient light, and the human eye will involuntarily perform visual adaptation when viewing the display; Adaptive adjustments make the user's eyes tired quickly

The invention provides a method and a device for adjusting backlight brightness of displays. The method comprises the following steps: acquiring illuminance signals corresponding to a plurality of first displays; wherein the first display is a display configured with an illuminance sensor, and the illuminance signal is generated by the illuminance sensor; generating a global control signal according to the illuminance signal corresponding to each first display; and controlling the backlight brightness of each first display by adopting the global control signal. According to the method, the illuminance signals of the plurality of first displays are used for generating a global control signal, and the backlight brightness of each first display is controlled by adopting the global control signal. On the premise that all the first displays are calibrated in a unified mode, the backlight brightness of all the first displays can be adjusted to be consistent. When a user switches to watch different first displays, the user does not feel the brightness difference of the first displays, and the eyes of the user do not need to adjust the adaptive state.
Description
technical field [0001] The present application relates to the technical field of display output, in particular to a method and device for adjusting backlight brightness of multiple display screens. Background technique [0002] With the maturity of display technology and the promotion of application requirements, various instruments and operation buttons on the side of the car cockpit are gradually converted from traditional mechanical instruments and buttons to mechanical instruments displayed on the display. In order to meet the application requirements, multiple monitors are installed on the driving side of the car. For example, most vehicles are equipped with at least one instrument display and central control display, and some high-end cars may also be provided with a passenger display and a door side display. [0003] When using the vehicle, the driver and occupant will observe the output information of each display according to their own needs, road conditions and th...
