1. A display panel, comprising:
a photosensitive array comprising photosensitive units arranged in an array;
an obtaining module connected to the photosensitive units and configured to obtain a photosensing data of the photosensitive array, wherein the photosensing data comprises a photosensing coordinate and a read data of at least one of the photosensitive units; and
a processing module connected to the obtaining module and configured to obtain an average photosensing coordinate of external light according to the photosensing coordinate and the read data of each of the photosensitive units to determine a display coordinate of the external light;
wherein the photosensing coordinate comprises a photosensing abscissa and a photosensing ordinate, and the average photosensing coordinate comprises an average photosensing abscissa and an average photosensing ordinate; and
the processing module is configured to obtain the average photosensing abscissa of the external light according to the photosensing abscissa and the read data of each of the photosensitive units;
wherein the display coordinate comprises a display abscissa of the external light; and
the processing module is configured to determine the display abscissa of the external light according to a total number of photosensing rows of the photosensitive units in the photosensitive array, a total number of display rows of subpixels of the display panel, and the average photosensing abscissa.
