1. A display panel, comprising:
a photosensitive array, wherein the photosensitive array comprises at least one set of photosensitive units arranged in an array;
an acquisition module, electrically connected to the photosensitive units and configured to acquire photosensitive data of the photosensitive array, and wherein the photosensitive data comprises previous frame photosensitive data and current frame photosensitive data; and
a process module, connected to the acquisition module, configured to acquire target frame photosensitive data according to a difference result between the current frame photosensitive data and the previous frame photosensitive data, and to determine a current frame display coordinate of an external light source based on the target frame photosensitive data, wherein the current frame display coordinate is a display coordinate corresponding to the current frame photosensitive data;
wherein the process module comprises a process unit and a storage unit; the process unit and the storage unit are connected to the acquisition module; the storage unit is configured to cache the previous frame photosensitive data; and the process unit is configured to determine the current frame display coordinate;
wherein the photosensitive data acquired by the acquisition module comprises a photosensitive coordinate of at least one of the photosensitive units and read-out data corresponding to the photosensitive coordinate; the process unit acquires target read-out data in the target frame photosensitive data according to a difference result between read-out data in the current frame photosensitive data corresponding to the same photosensitive coordinate and read-out data in the previous frame photosensitive data, and acquires a current frame average photosensitive coordinate of the external light source based on the photosensitive coordinate of each of the photosensitive units and the target read-out data corresponding to the photosensitive coordinate, and the current frame average photosensitive coordinate is an average photosensitive coordinate corresponding to the current frame photosensitive data;
wherein the photosensitive coordinate comprises a photosensitive abscissa and a photosensitive ordinate; the current frame average photosensitive coordinate comprises a current frame average photosensitive abscissa and a current frame average photosensitive ordinate; and the process unit acquires the current frame average photosensitive abscissa of the external light source based on the photosensitive ordinate and the target read-out data corresponding to each of the photosensitive units.
