Abstract
An electrophoretic display device with an improved reflective luminance is presented. The electrophoretic display device includes an electrophoretic display panel including sub-pixels corresponding to four colors (e.g., red, green, blue, and white). A signal converter is provided for receiving an image signal for three colors and converting it into an image signal for four colors. A data driver is provided for supplying the converted image signal for four colors to the sub-pixels as a data voltage.
