Display apparatus and method of driving the same using photonic and electrophoresis principle

摘要

A display apparatus includes an image data comparator which receives first, second and third color image data, extracts first, second and third image data from the first, second and third color image date by comparing gray scale values of the first, second and third color image date such that each of grayscale values of the second and third image data is greater than or equal to a gray scale value of the first image data, and compares the gray scale value of the first image data with a predetermined gray scale value, a driving circuit which generates a gray scale signal based on a result of the comparison and generates first and second color signals based on the first, second or third image data, and a pixel including a first sub-pixel which receives the gray scale signal, second and third sub-pixels which receive the first and second color signals, respectively.

1. A display apparatus comprising:
an image data comparator which receives a pixel image data including a first color image data, a second color image data and a third color image data, extracts a first image data, a second image data and a third image data from the first color image data, the second color image data and the third color image data by comparing gray scale values of the first color image date, the second color image data and the third color image data with each other such that each of a grayscale value of the second image data and a grayscale value of the third image data is greater than or equal to a gray scale value of the first image data, and compares the gray scale value of the first image data with a predetermined gray scale value; a driving circuit which generates a gray scale signal based on a compared result of the gray scale value of the first image data and the predetermined gray scale value and generates a first color signal and a second color signal based on at least one of the first image data, the second image data and the third image data, wherein each of the first and second color signals includes at least one color information; and a pixel including a first sub-pixel which receives a gray voltage corresponding to the gray scale signal to display a gray scale, a second sub-pixel which receives a first driving voltage corresponding to the first color signal to display at least two primary colors, and a third sub-pixel which receives a second driving voltage corresponding to the second color signal to display at least two primary colors, wherein a wavelength of each color displayed from the second sub-pixel and the third sub-pixel is corresponding to each of the first driving voltage and the second driving voltage, wherein the predetermined gray scale value is obtained by multiplying a maximum gray scale value of the pixel image data by a ratio of a maximum reflectance of the first sub-pixel to a maximum reflectance of the pixel.
