The present invention provides a voltage transfer function, a luminance transfer function, and a transfer factors (for example, efficiency, critical point, and slope) between these two functions, derives the correlation (based on the condition change in all cases) between an input grayscale voltage and output luminance, and calibrates the input grayscale voltage by a difference between measurement luminance and target luminance using the transfer functions. Therefore, the present invention can respond to change in conditions for all cases, and increase the accuracy, easiness, and generalization of calibration compared to the existing calibration scheme that relies on the lookup table by checking the actual measurement data and readjusting the transfer factors in each calibration stage. Moreover, the present invention can further increase the manufacturing yield by an average of 35% than the existing yield, significantly saving the manufacturing cost. |
