Abstract
A pixel driving chip and a driving method therefor, and a display apparatus. The pixel driving chip includes a data input circuit, a time selection circuit, and a current control circuit; the data input circuit is configured to receive display data, and partition the display data to obtain a data partition to which the display data belongs in M data partitions that are obtained on the basis of a display data range; the time selection circuit is configured to determine, according to the data partition to which the display data belongs, an output time length corresponding to the display data, and within the output time length, output the display data to the current control circuit; the current control circuit is configured to determine, according to the display data, a driving current flowing through a light emitting element corresponding to the display data.
