Abstract
Official abstract text for this publication.
A method of displaying an image on a display panel which comprises a plurality of pixels arranged as a matrix type includes measuring a tristimulus value of X, Y and Z values of a displayed image to generate a target curve, generating a corrected grayscale data of a red pixel, a green pixel and a blue pixel using X, Y and Z values of the target curve and converting the corrected grayscale data to a data voltage to provide a data line of the display panel with the data voltage.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of displaying an image on a display panel which comprises a plurality of pixels arranged as a matrix type, the method comprising: measuring a tristimulus value of X, Y and Z values of a displayed image to generate a target curve; generating corrected grayscale data of a red pixel, a green pixel and a blue pixel using the X, Y and Z values of the target curve; and converting the corrected grayscale data to a data voltage to provide a data line of the display panel with the data voltage. 2 . The method of claim 1 , wherein the generating corrected grayscale data comprises: calculating target grayscale values of the red pixel, the green pixel and the blue pixel using the X, Y and Z values of the target curve; calculating a variation of the red pixel, the green pixel and the blue pixel using the calculated target grayscale values of the red pixel, the green pixel and the blue pixel; and applying the variation of the red pixel, the green pixel and the blue pixel to a grayscale value corresponding to the displayed image to generate a corrected grayscale data. 3 . The method of claim 2 , wherein the target grayscale values of the red pixel, the green pixel and the blue pixel are defined by the following Equations: Red Target Gray = Max Gray × G Red target 1 Red Gamma Green Target Gray = Max Gray × G Green target 1 Green Gamma Blue Target Gray = Max Gray × G Blue target 1 Blue Gamma wherein the Red Target Gray is a red target grayscale value, the Green Target Gray is a green target grayscale value, the Blue Target Gray is a blue target grayscale value and the MaxGray is a maximum grayscale value in a pixel, and wherein the G Redtarget , the G Greentarget and the G Bluetarget are defined by the followng Equation: ( G Red target G Green target G Bluetarget ) = ( X Red Max Gray - 1 X GreenMax Gray - 1 X BlueMax
