the color temperature detector detects color temperature data of the spliced screen and sends the color temperature data to the color regulator, and the color regulator realizes the spliced screen color regulation method through the color temperature data sent by the color temperature detector as follows:
s201: acquiring color temperature data of the backlight of a reference screen and other display screens in the spliced screen;
s202: judging whether the difference between the color temperature data of the reference screen and the color temperature data of the display screen meets the requirement, if so, executing S204, and if not, executing S203;
s203: determining a light source needing to be adjusted in the backlight of the display screen according to the difference of the color temperature data, and adjusting the voltage of the light source to enable the difference between the color temperature data of the reference screen and the color temperature data of the display screen to meet the requirement;
s204: and determining that the backlight of the reference screen is consistent with the backlight of the display screen.
7. The tiled screen color tuning system of claim 6, wherein the color temperature data comprises color coordinate data, luminance data of the backlight.
8. The system for adjusting the color of a spliced screen as claimed in claim 7, wherein the step of determining whether the difference between the color temperature data of the reference screen and the color temperature data of the display screen meets the requirement specifically comprises:
acquiring a color coordinate data difference and a brightness data difference according to the color temperature data of the reference screen and the display screen, and judging whether the color coordinate data difference and the brightness data difference are respectively in a preset range;
if yes, determining that the requirements are met;
if not, determining that the requirements are not met.
9. The system for adjusting color of a tiled display screen according to claim 8, wherein the step of determining the light source to be adjusted in the backlight of the display screen according to the difference between the color temperature data specifically comprises:
acquiring color temperature data corresponding to the difference between the color temperature data which do not meet the requirements, and judging whether the color temperature data are color coordinate data or not;
if so, acquiring coordinates which do not meet the requirements in the color coordinate data, and determining a light source needing to be adjusted in the red light source and the green light source according to the coordinates;
and if not, determining that the blue light source in the backlight is the light source needing to be adjusted.
10. A storage device, characterized in that the storage device stores program data used for executing the mosaic screen color adjustment method according to any one of claims 1-5.
