Display driver ic for image correction of amoled

Abstract

The present invention relates to a display driver IC for AMOLED image correction optimized for external compensation to solve problems such as MURA and image sticking of an AMOLED panel, and more specifically, to a display driver IC for AMOLED image correction, which comprises a first compensation circuit section, a conversion circuit section, a second compensation circuit section, and a driving circuit section, and obtains compensation data for luminous efficiency deviation rate (ΔLU) of a light-emitting diode and beta value deviation rate (ΔBeta) of a thin film transistor in a gamma curve domain between luminance and video data, and compensates for threshold voltage deviation rate (ΔVT) of a thin film transistor by obtaining compensation data in a gamma curve domain between luminance and driving voltage and then adding them up.
