Abstract:
1. A stereoscopic image display system, comprising: a three-dimensional (3D) image signal generator configured to separate an image signal into first left-eye frame data and first right-eye frame data and down-scale the first left-eye frame data and the first right-eye frame data to generate precede left-eye data and precede right-eye data, respectively; a display panel including data lines, gate lines, and pixels; a timing controller configured to receive the precede left-eye data and the precede right-eye data from the 3D image signal generator, output left-eye data and right-eye data during a first mode, and output second left-eye frame data and second right-eye frame data obtained by up-scaling the precede left-eye data and the precede right-eye data during a second mode; a data driver configured to output a first left-eye data voltage and a first right-eye data voltage, which are generated based on the left-eye data and the right-eye data, to the data lines at a first frequency during the first mode, and output a second left-eye data voltage and a second right-eye data voltage, which are generated based on the second left-eye frame data and the second right-eye frame data, to the data lines at a second frequency during the second mode; and a gate driver configured to apply a first gate signal to the gate lines at the first frequency during the first mode and apply a second gate signal to the gate lines at the second frequency during the second mode, wherein two pixels, which are respectively connected to an i-th gate line and an (i+l)th gate line among the gate lines and to a same data line among the data lines, have a same driving time in the first and second modes, where i is an odd number equal to or larger than 1, wherein the precede left-eye data comprises a plurality of left-eye half-row data, and the precede right-eye data comprises a plurality of right-eye half-row data, wherein the timing controller generates left-eye compensation data based on the left-eye half-row data and generates right-eye compensation data based on the right-eye half-row data, wherein a j-th left-eye compensation data of the left-eye compensation data has a data value obtained by interpolating a j-th left-eye half-row data and a (j+1)th left-eye half-row data among the left-eye half-row data, and a j-th right-eye compensation data of the right-eye compensation data has a data value obtained by interpolating a j-th right-eye half-row data and a (j+1)th right-eye half-row data among the right-eye half-row data, where j is a natural number, and wherein the second left-eye data voltage comprises a left-eye data voltage obtained by converting the left-eye half-row data and a left-eye compensation voltage obtained by converting the left-eye compensation data, and the second right-eye data voltage comprises a right-eye data voltage obtained by converting the right-eye half-row data and a right-eye compensation voltage obtained by converting the right-eye compensation data.
