Display device and driving method thereof
First Claim
1. A display device, comprising:
- an image attribute signal generating portion analyzing red (R), green (G), and blue (B) input data signals and generating a plurality of attribute signals;
a signal treating portion connected to the image attribute signal generating portion, the signal treating portion converting the R, G, and B input data signals to R, G, and B output data signals using the plurality of attribute signals, wherein the R, G, and B input data signals have first brightness levels, wherein R, G, and B input data signals used to display images having colors other than white are converted to R, G, and B output data signals, wherein the R, G, and B output data signals have second brightness levels, wherein the second brightness levels are lower than the first brightness levels; and
a display portion having a plurality of pixels, wherein each pixel includes R, G, and B sub-pixels, and wherein the R, G, and B output data signals are supplied to respective ones of the R, G, and B sub-pixels.
