The invention discloses a correction method and device of a display device and a processor. The method comprises the following steps: determining an acquisition range on a display device; determiningthe positions of a plurality of acquisition point positions according to the acquisition range, the acquisition area of a first acquisition device and the number of the acquisition point positions; acquiring a plurality of display data at a plurality of acquisition point locations through the first acquisition device, and acquiring second display data in the acquisition range through a second acquisition device; determining a curved surface compensation coefficient according to third display data corresponding to the plurality of acquisition point locations in the plurality of first display data and the second display data; and correcting the second display data according to the curved surface compensation coefficient, and correcting the display device through the corrected second displaydata. According to the invention, the technical problems of inaccurate display data acquired according to a camera and poor display quality after correction according to the display data caused by thecurved surface problem of the display device in the prior art are solved.
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...
