Client needs for better display effect soar as E-paper display develops. Our engineers have now realized the 4 level grayscale display effect of UC series E-paper displays. The basic principle is: There are usually four registers in the driver IC that supports tricolor display effect. UC series need all the four registers to display 4 grayscale because they can record display data and contrast them by turn to display 4 grayscale image.
