Method and device for obtaining compensation parameter for pixel data and AMOLED display panel

摘要

The present disclosure relates to a method and a device for obtaining a compensation parameter for pixel data, and an AMOLED display panel. The method for obtaining a compensation parameter for pixel data includes: obtaining a sensing voltage value of a driving transistor in each of pixel units in an AMOLED display screen in a first state; obtaining a sensing voltage value of a driving transistor in each of the pixel units in a second state; determining a compensation parameter of pixel data for each of the pixel units based on the sensing voltage values in the first state and the second state; the sensing voltage value refers to a potential value at a terminal of the driving transistor coupled with a display diode after the pixel data is written; the compensation parameter is used for compensating the pixel data in the subsequent display process.
