Abstract

The invention discloses a calibration method, a device and a processor of a display device. Wherein, the method includes: determining the collection range on the display device; determining the positions of multiple collection points according to the collection range, the collection area of ​​the first collection device, and the number of collection points; Collect a plurality of first display data at the collection point, and collect the second display data in the collection range through the second collection device; according to the third display data corresponding to the plurality of collection points in the first display data and the second display data , determining the surface compensation coefficient; correcting the second display data according to the surface compensation coefficient, and correcting the display device through the corrected second display data. The invention solves the technical problems in the related art that the display data collected by the camera is inaccurate due to the curved surface problem of the display device, and the display quality corrected according to the display data is poor.

Description

technical field [0001] The present invention relates to the field of data control, in particular to a calibration method and device for a display device, and a processor. Background technique [0002] With the development of LED display technology, LED displays are currently being applied to various fields due to their advantages of low cost, low power consumption, high visibility, and free assembly. At the same time, with the popularization of LED display applications, people have higher and higher requirements for its display quality. Therefore, how to improve the display quality of LED display screens has become a research hotspot in this field. [0003] The uniformity of the LED screen is an important factor to improve the display quality. At present, the chromaticity of the LED light is collected through the camera, and then the correction coefficient of each light point is generated to correct it to the same level. It is usually a data-driven method, and the LED displ...
