AI Technical Summary

Problems solved by technology

When the color electronic paper displays the color of charged particles with a higher threshold voltage, a voltage is applied to the upper electrode and the lower electrode so that the voltage difference between the upper electrode and the lower electrode meets the threshold voltage of the charged particles with a higher threshold voltage. Both the charged particles with high threshold voltage and the charged particles with low threshold voltage are driven from the lower substrate to the upper substrate, and in order to realize the monochrome display of charged particles with higher threshold voltage, it is necessary to apply a reverse voltage to the upper electrode and the lower electrode to The charged particles with a low threshold voltage are returned to the lower substrate, but since the charged particles with a higher threshold voltage are located on the upper side of the display area of ​​the color electronic paper, and the charged particles with a lower threshold voltage are located on the lower side of the display area of ​​the color electronic paper, different Layered arrangement of charged particles of color, causing color shift problems
