Electronic label device

Abstract

An electronic label device includes a display module and a driving chip. The display module includes a driving substrate and an E-paper film, and the E-paper film is disposed on the driving substrate. The driving chip is disposed on the driving substrate and is electrically connected to the driving substrate. The driving chip drives the E-paper film to display images through the driving substrate. The driving chip includes a memory unit, which stores a plurality of lookup tables corresponding to a plurality of temperature ranges. Each lookup table includes an index corresponding to one of the temperature ranges and a plurality of processing procedures for multiple display colors of the E-paper film, and the index indicates a driving mode of the processing procedures.
