A system and method for compensating an AMOLED voltage drop. The system for compensating an AMOLED voltage drop comprises an AMOLED display panel that is divided into multiple regions, and comprises a picture detection module, a data signal correction module and a voltage drop compensation module. The method for compensating an AMOLED voltage drop comprises: dividing an AMOLED display panel into multiple regions in the extension direction of power source wiring (L); detecting data signals of a to-be-displayed picture by means of a picture detection module; determining whether the to-be-displayed picture is a pure color picture; converting the data signals of the pure color to-be-displayed picture by means of the data signal correction module; and adjusting data signal variations of sub-pixels in each region of the AMOLED display panel by means of a voltage drop compensation module, so as to implement region-based voltage drop linear compensation on multiple regions. By means of the system and method for compensating an AMOLED voltage drop, region-based voltage drop linear compensation is implemented, and voltage drops are effectively compensated, thereby resolving the problem of uneven picture quality caused by the voltage drop when a pure color picture is displayed in the AMOLED display panel. |
