Technical Problem
[0003]现有技术中，因电子纸产品页面区所使用的驱动波形是和页面边框区所使用的驱动波形是一样的，但因为页面区是正常像素充电的方式进行驱动，页面边框区并不是充电的像素方式进行驱动，而是有和VCOM电压一起进行驱动，两者实际驱动粒子的电压并不一样所以页面边框区非常容易刷新成异色，且非常难调试解决此问题
Benefits of technology
[0026] The color elimination module is used to call the second waveform voltage data to refresh the first image display area of the first electronic price tag, and at the same time call the VCOM drive waveform voltage data to refresh the second image display area of the first electronic price tag, so as to obtain the electronic price tag after page refresh.
