Abstract

The present application provides a method and device for obtaining correction data, wherein the method includes: obtaining the pixel layout of the light-emitting diode (LED) cabinet, and establishing a solid-color picture with the pixel layout, and projecting the solid-color picture onto The LED box is displayed; according to the brightness and darkness of the corresponding LED box splicing in the projection screen, adjust the brightness of the pixel point corresponding to the splicing position on the solid color picture; after the adjustment is completed, an adjustment coefficient is generated, After correcting the original calibration data according to the adjustment coefficient, the new calibration data is obtained. Using the above scheme, the problem of inaccurate calibration data for brightness adjustment of the LED display screen in the related art is solved. Obtaining the calibration data for the LED display to be adjusted eliminates the need for frequent operations on the LED display.

Description

technical field [0001] The present application relates to but not limited to the display field, and in particular, relates to a method and device for obtaining correction data. Background technique [0002] In the related art, the method for adjusting light-emitting diode (Light Emitting Diode, referred to as LED) display splicing bright and dark lines includes the following: Method 1, directly adjust the distance between two adjacent columns (or rows) of LED pixels at the splicing position . That is to resplice adjacent LED modules (or adjacent LED boxes) with bright and dark lines. Method 2: The technicians manually correct the calibration data of the LED pixels at the splicing position according to experience. [0003] However, the efficiency of the above method 1 is low, even after re-splicing, bright and dark lines still exist. The second method is inefficient and has large errors, and may require multiple adjustments to the correction data of the LED pixels at the s...
