Abstract

The invention discloses a display screen correction method and device. The method comprises the following steps: determining a plurality of to-be-collected areas of a display screen and position coordinates of the plurality of to-be-collected areas in a display area of the display screen; according to the plurality of position coordinates, determining a plurality of target positions of the plurality of to-be-collected areas respectively collected by the first collection device; acquiring an initial position of the first collection device, controlling the first collection device to move to a plurality of target positions according to the initial position, and respectively acquiring a plurality of standard display data of the plurality of to-be-collected areas; and correcting the display screen according to the plurality of standard display data and the display data corresponding to the plurality of to-be-collected areas in the full-screen data of the display screen acquired by the second collection device. According to the invention, the technical problems of tedious operation and low efficiency of a mode of collecting display screen data through a colorimeter or a correction collection device and correcting the display screen in the prior art are solved.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a method and device for calibrating a display screen. Background technique [0002] Due to the limitations of the LED's own luminescence curve and the acquisition device, an obvious gradient phenomenon will be found after the display is calibrated, which greatly affects the consistency of the display and the viewing experience of the user. In the related technology, in the process of calibration through the calibration acquisition device, when performing gradient correction, it is necessary to repeatedly move the box relative to the calibration acquisition device, which requires high manual operation and complicated operation, and also affects the calibration efficiency. . Alternatively, the colorimeter is manually operated to collect data from multiple collection areas on the LED display screen, and then combined with the data collected by the calibration collection device for co...
