Whether it is paper labels or electronic shelf labels, the most basic function is to display the price of goods and other information, such as promotional signs, multi-currency prices, unit prices, inventory and so on. In addition, according to the current use of supermarket labels and regional distribution, in addition to Chinese, English, Japanese, even Persian, Arabic and other small languages. Therefore, to display the content of electronic tags perfectly, simply burning the word base as in the past can no longer meet this requirement, because the instability or incompleteness of the burning process will cause defects in its own solutions, thus affecting the customer's use experience.
