1. A charging time modulating method, configured to modulate charging time of a display panel, wherein the display panel comprises a plurality of pixel areas arranged along a first direction, and each of the pixel areas comprises a plurality of pixel units arranged along a second direction, wherein the charging time modulating method comprises steps of:
obtaining relational data between a charging rate and a charging time of the pixel units on each of the pixel areas;
calculating an average charging time corresponding to a preset charging rate based on the relational data between the charging rate and the charging time of the pixel units on each of the pixel areas;
obtaining an initial charging time of the pixel units on each of the pixel areas; and
adjusting the initial charging time of the pixel units on each of the pixel areas according to the average charging time, so that the initial charging time of the pixel units on each of the pixel areas is equal to the average charging time;
wherein the step of obtaining the relational data between the charging rate and the charging time of the pixel units on each of the pixel areas comprises:
obtaining the charging time and the charging rate of each of the pixel units on each of the pixel areas; and
according to the charging time and the charging rate of each of the pixel units on each of the pixel areas, generating the relational data between the charging rate and the charging time of the pixel units on the corresponding pixel area; and
the step of calculating the average charging time corresponding to the preset charging rate based on the relational data between the charging rate and the charging time of the pixel units on each of the pixel areas comprises:
obtaining the preset charging rate;
obtaining a charging time corresponding to the preset charging rate of the pixel units on each of the pixel areas according to the relational data between the charging rate and the charging time of the pixel units on each of the pixel areas; and
calculating the average charging time based on the charging time corresponding to the preset charging rate of the pixel units on each of the pixel areas.
