Stereoscopic image display device and method for driving the same

摘要

Embodiment relate to a display panel that modulates 3D image data based on pixel data of adjacent lines. The display panel includes data lines, gate lines, and a plurality of pixels; a data modulation unit. The modulation unit modulates kth pixel data of a jth line in 3D image data based on the kth pixel data of the jth line and kth pixel data of a line adjacent to the jth line. The data driving circuit converts the modulated 3D image data into analog data voltages and outputs the analog data voltages to the data lines. A gate driving circuit sequentially outputs gate pulses to the gate lines.

1. A stereoscopic image display device comprising:
a display panel comprising data lines, gate lines, and a plurality of pixels; a patterned retarder on the plurality of pixels of the display panel and comprising a first retarder formed on odd-numbered lines of the pixels to polarize light from the odd-numbered lines of the pixels in a first direction and a second retarder formed on even-numbered lines of the pixels to polarize light from the even-numbered lines of the pixels in a second direction different from the first direction; a data modulation unit configured to generate modulated 3D image data, the data modulation unit comprising (i) a memory configured to store pixel data of an adjacent pixel or a target pixel and (ii) a data calculator coupled to receive the stored pixel data of the adjacent pixel or the target pixel from the memory, the data calculator configured to calculate pixel data for a pixel in the modulated 3D image data at a same location as the target pixel by adding a difference between the pixel data of the target pixel and the pixel data of the adjacent pixel multiplied by a parameter to the pixel data of the target pixel, the adjacent pixel at a same column as the target pixel and in another row of image data adjacent to the row of the target pixel; a data driving circuit configured to convert the modulated 3D image data into analog data voltages and output the analog data voltages to the data lines; and a gate driving circuit configured to sequentially output gate pulses to the gate lines.
