Electronic paper display unit and mobile communication terminal having the same
First Claim
1. An electronic paper display unit comprising:
- a protective case, which is made of a transparent material;
a display installed in the protective case and configured to display a desired image information, the display divided into a plurality of divided regions configured to function as independent units; and
a control module electrically connected to the display and configured to operate in a first mode for transmitting a divided mode signal such that a plurality of pieces of an image information are independently displayed on the divided regions and a second mode for transmitting an integrated mode signal such that one piece of an image information is displayed throughout the divided regions, wherein an outermost one of the divided regions includes a plurality of sub-regions that are curved on an outer circumference of the divided regions, each curved sub-region being powered to display at least a portion of the image information, a contrast of which is gradually increased from a first end to a second end of the curved sub-region.

11. A method of operating an electronic paper display unit comprising:
-
providing a display in a transparent protective case, the protective case for installing on an outer face of a mobile communication terminal within a predetermined thickness; and transmitting a mode signal to the display such that an image information is displayed on each of a plurality of divided regions of the display that function independently, wherein the mode signal corresponds to one of a first mode for transmitting a divided mode signal such that a plurality of pieces of the desired image information are independently displayed on the plurality of divided regions of the display and a second mode for transmitting an integrated mode signal such that one piece of the desired image information is displayed throughout the plurality of divided regions of the display, and wherein an outermost one of the divided regions includes a plurality of sub-regions that are curved on an outer circumference of the divided regions, each curved sub-region being powered to display at least a portion of the image information, a contrast of which is gradually increased from a first end to a second end of the curved sub-region. - View Dependent Claims (12, 13, 14, 15, 16, 17)
