At present, vehicle-mounted interactive display is mainly realized by using a vehicle-mounted machine to control an LCD or OLED screen, but the cost is high, and a large amount of arrangement can not be carried out at different positions in a vehicle.
At present, the interactive display control of the LED array in the vehicle is mainly divided into two types from the realization mode: a first type, for example, patent application No. CN201980074093.3 discloses an LED controller system comprising an LED controller comprising an image frame buffer capable of receiving image data. A sensor processing module is used to receive and process the sensor data and a decision module is used to determine an action to take in response to the processed sensor data. An image creation module is used to create an image to be sent to an image frame buffer of the LED controller. The method can control the brightness of the single-color LED array so as to display a single color image, but does not consider the influence of the ambient temperature on the brightness consistency and the system reliability, and meanwhile, the brightness and the color of the RGB LED array cannot be controlled so as to display a color image, and the influence of the ambient temperature on the brightness and the chromaticity consistency of the light source and the system reliability is avoided.
The second category, patent application No. CN201780081525.4, discloses a lighting system for controlling an LED array. The lighting system includes: an LED array comprising a plurality of individually addressable light sources L1-L15, each light source having an individual address; a processor configured to divide the plurality of individually addressable light sources L1-L15 into a plurality of light source segments by assigning segment addresses to the light source segments, wherein each segment comprises a unique set of one or more light sources; wherein the LED array further comprises a receiver configured to receive a plurality of illumination control signals via a network, wherein each illumination control signal is addressed to one of the segment addresses; and wherein the LED array further comprises a controller configured to control at least one of the individually addressable light sources of each segment in accordance with an illumination control signal addressed to the respective segment. This approach can perform brightness and color control for RGB LED arrays, but because of the segmented control, high pixel color images cannot be displayed, and the effects of ambient temperature on light source brightness chromaticity uniformity and system reliability are not considered.
Therefore, if the independent interactive display control can be carried out on each light source pixel point in the RGB LED array, the influence of the ambient temperature on the brightness and chromaticity consistency of the RGB light source and the system reliability is solved, the brightness and chromaticity defect and the system thermal damage which can be perceived by human eyes are avoided, the interactive display in the vehicle can be realized through the RGB LED array screen, the product cost is obviously reduced, and the rapid development of related industries is promoted.
