Abstract
A light emitting display apparatus has pixels arranged in rows to display a predetermined image, each of the pixels being composed of red and green, or blue and yellow light emitting diodes, lenses provided on the pixels, each of the lenses horizontally diffusing lights emitted from the red and green, or blue and yellow light emitting diodes, and vertically diverging the lights, a driver for driving the red and green, or blue and yellow light emitting diodes to be turned on in accordance with predetermined light intensities, thereby representing various colors including a white color. In the light emitting display apparatus, therefore, the displayed image is easy to be recognized, the number of the LEDs and the power consumption are decreased, and the density of pixels is increased. Further, the image information of the white color is displayed without the three original color light emitting diodes, that is, red, green and blue light emitting diodes, and the color of an image information is selectable from a variety of colors which include a white color.
