Background

At present, electronic display products are various in types and have various characteristics. Especially, color Display products are widely used, wherein Color electronic Paper realizes Color Display by using Electrophoretic (EPD) and Color Filter (CF) technologies. The display medium layer or electronic ink of the electronic paper display device is mainly composed of electrophoretic liquid and white and black particles mixed in the electrophoretic liquid. By applying voltage to the display medium layer, the white and black particles can be driven to move, so that each pixel displays black, white or gray scale. Ambient light is irradiated to the display medium, and the display medium reflects the light, so that patterns and characters formed by black and white particles can be seen finally. The matched color filter CF is arranged at a proper position between the display medium and human eyes, and the reflected light of the display medium passes through the color filter CF, so that colored patterns and characters can be displayed. The electronic paper has the function of low power consumption because patterns and characters can be kept for a long time after power failure, and meanwhile, the electronic paper display product achieves the purpose of display by irradiating the display medium layer with incident light rays, so that a backlight source is not needed, and the power consumption of the reflective display product can be saved.
