Claim 6:
7. The brightness compensation method as claimed in claim 6, wherein establishing the brightness-corrected-value regional-viewing-angle relational database of the mapping relation between the regional viewing angle of the at least one region and the brightness correction value of the at least one region comprises:
configuring a shortest distance from the optical center of the lens of the photographing component to the display panel to be a normal work distance;
using the photographing component to photograph the display panel, and obtaining images of reference regions respectively in different regional viewing angles under the preset grayscale;
obtaining brightness correction values and corresponding viewing angles of the images of the reference regions respectively in the different regional viewing angles under the preset grayscale to establish the brightness-corrected-value regional-viewing-angle relational database.
