Patent ID: 8405585

Claim:
An OLED display, comprising: a display panel comprising a plurality of sub-pixels; a memory storing a compensation table containing information for Mura compensation, wherein said compensation table is initially established based on the characteristic of each sub-pixel and the average luminance of said plurality of sub-pixels; and a processing circuit, comprising: a current sensor sensing a sum of currents of a group of sub-pixels among said plurality of sub-pixels, wherein said compensation table is updated according to said sensed current; and a processor receiving an image data and generating compensated image data based on said image data and said updated compensation table; wherein said display panel displays said compensated image data by driving said plurality of sub-pixels, including said at least one sub-pixel that is sensed by the current sensor, to emit light in response to said compensated image data, whereby Mura defect is compensated.
