Abstract: A method of operating an electronic paper display, an electronic paper display, an apparatus for operating an electronic paper display, an apparatus for driving an electronic paper display, and an electronic shelf label including an electronic paper display are disclosed. The method of operating an electronic paper display involves, setting a display area to be a first color by operating, for a first duration, a transparent common electrode at a first level and segment electrodes, which comprise a data electrode and a background electrode, at a second level; and in response to the display area being set to be the first color, setting the display area to be a second color by operating, for a second duration different from the first duration, the transparent common electrode at the second level and the background electrode at the first level.

Abstract: A technology regarding electronic labels that electronically show information regarding products displayed in a store. The proposed invention independently displays product information of different types through two displays and thus reduces power consumption by using LCD panels. In addition, other aspects of the proposed invention make better use of space by mounting a display panel on a bezel area, and also lower a product's unit cost of production as products, more specifically the two displays therein, may be controlled using only one controller. Furthermore, the proposed invention may allow for the displayed product information to be changed even when the electronic label is in sleep mode.
