Abstract
A method for generating display information of an electronic price tag includes: comparing supported colors of the electronic price tag with a display color of each pixel in each to-be-displayed region, and dividing the each to-be-displayed region into a to-be-adjusted display region and a normal display region according to a comparison result; determining a target color of each pixel from the supported colors of the electronic price tag according to a display color of the each pixel in the to-be-adjusted display region; generating a rendering result of to-be-displayed information according to the target color of the each pixel in the to-be-adjusted display region and a display color of each pixel in the normal display region, and sending the rendering result of the to-be-displayed information to the electronic price tag so that the electronic price tag displays the rendering result of the to-be-displayed information.
