Abstract
A digital television (TV) including a display terminal, a TV chip and an image driving circuit is provided. The display terminal includes multiple adjacent rows of pixels. The TV chip includes a digital TV decoder, a data stream decoder, a scaler and a color space converting circuit. The digital TV decoder outputs a data stream according to an interlaced TV signal. The data stream decoder decodes the data stream to output an interlaced image. The scaler outputs a scaled image according to the interlaced image. The color space converting circuit outputs color pixel data according to the scaled image. The image driving circuit simultaneously turns on the rows of pixels, and writes the color pixel data into the rows of pixels to display a de-interlaced image.
