Luminance correcting system and luminance correcting method for organic light emitting display

摘要

A luminance correcting system for an organic light emitting display includes an image analyzing unit for analyzing an image on a display unit and for measuring luminance and color coordinates of reference gray level data, a reference offset value setting unit for setting reference offset values of respective color data in the reference gray level data to correspond to an image analysis result obtained by the image analyzing unit, a controller for detecting a difference in reference offset values of at least two color data among the respective color data in the reference gray level data and for comparing the difference with a reference value, and an additional offset value setting unit for setting an additional offset value corresponding to at least one gray level among gray level data excluding the reference gray level data when the difference in the reference offset values is not less than the reference value.

1. A luminance correcting method for an organic light emitting display, comprising:
analyzing an image displayed on a display unit of the organic light emitting display and measuring luminance and color coordinates of reference gray level data; setting reference offset values corresponding to respective color data in the reference gray level data corresponding to an image analysis result; detecting a difference between a first reference offset value corresponding to a first color from among the reference offset values and a second reference offset value corresponding to a second color from among the reference offset values, the first color being different from the second color, and comparing the difference with a reference value, wherein the difference between the first and second reference offset values is a numerical value that is compared with the reference value; and setting an additional offset value corresponding to at least one gray level among remaining gray level data excluding the reference gray level data when the difference between the first reference offset value and the second reference offset value is not less than the reference value.
