Patent ID: 8902297

Claim:
A stereoscopic image display, comprising: a display panel configured to display two-dimensional (2D) image data in a 2D mode and display three-dimensional (3D) image data in a 3D mode; a gamma reference voltage generating circuit configured to generate first gamma reference voltages for the two-dimensional image data and second gamma reference voltages for the three-dimensional image data, output the first gamma reference voltages in the 2D mode, and output the second gamma reference voltages in the 3D mode, the first gamma reference voltages being different from the second gamma reference voltages; and a data driver configured to convert the 2D image data into a 2D data voltage based on the first gamma reference voltages in the 2D mode and output the 2D data voltage to data lines of the display panel, and convert left eye image data and right eye image data into a 3D data voltage based on the second gamma reference voltages in the 3D mode and output the 3D data voltage to the data lines of the display panel, wherein the first gamma reference voltages include a first peak white gray level voltage less than a predetermined high potential power voltage, and the second gamma reference voltages include a second peak white gray level voltage less than the predetermined high potential power voltage, wherein the second peak white gray level voltage is greater than the first peak white gray level voltage, wherein a gamma curve of the 2D image perceived by a user is the same as the gamma curve of the 3D image perceived by the user, and wherein the first gamma reference voltages and the second gamma reference voltages allow a gamma curve of the 3D image to coincide a gamma curve of the 2D image.
