Picture detection method and display panel
By determining the range and continuity of monochrome frame grayscale data in the image detection method, and only changing the polarity flip mode of frame image data with continuous grayscale changes, the flickering or screen tearing problem caused by the image detection function is solved, and the display quality is improved.

AI Technical Summary
Technical Problem
The screen detection function is prone to flickering or screen tearing when processing special scenes, which reduces the quality of the display.
Method used
By determining whether the monochrome frame grayscale data conforms to the preset grayscale range and remains in multiple consecutive frame image data, the polarity inversion mode is changed only for frame image data with continuously changing grayscale.
Benefits of technology
The brightness jumps corresponding to consecutive frame image data have been reduced, improving the flickering or screen tearing caused by the image detection function.

Abstract
This application discloses a screen detection method and a display panel. The screen detection method first determines that the grayscale data of a monochrome frame is within a preset grayscale range, and then determines whether the grayscale data of the monochrome frame is maintained in multiple consecutive frame image data. It can change the polarity inversion mode of the frame image data with continuously changing grayscale only, thereby reducing the jump in display brightness corresponding to consecutive frame image data and improving the technical problem of flickering or screen tearing caused by the screen detection function.
