The present invention includes a control unit, a first wireless transmitting module is coupled to the control unit. A second wireless transmitting module is coupled to the control unit, a display having a first electrode formed on a first substrate, a second electrode formed on a second substrate, at least three color elements formed between the first electrode and the second electrode, each the at least three color elements are formed with emitting substances, wherein a bias is applied to excite the emitting substances by combination of an electron and a hole; a display status memory coupled to the display to store displaying status.

A control unit for a transport refrigeration device comprises a multi-color display for displaying at least one view including at least one graphical element, a memory storing two or more color settings for the multi-color display, wherein the color settings define illumination colors of the multi-color display, and a processing unit operatively coupled with the multi-color display and the memory to cause applying a color setting to the multi-color display of the transport refrigeration device, and displaying the view using the applied color setting, wherein the at least graphical element is illuminated in a color defined by the applied color setting.

Disclosed herein is an refrigerator. The refrigerator includes a body provided with a storage chamber, a door configured to open or close the storage chamber, a display unit provided on the door, and a heat radiating unit disposed adjacent to the display unit and configured to radiate a heat generated in the display unit via a heat radiating flow path formed inside the door, wherein one end of the heat radiating flow path is communicated with the outside via a first hole formed in an upper end portion of the door, and the other end of the heat radiating flow path is communicated with the outside via a second hole formed in a lower end portion of the door.

A method to control a refrigerator includes changing a transparent display assembly to be in a first or transparent state allowing an inner space of the refrigerator to be visible through the transparent assembly, a second or opaque state so as to conceal the inner space, and a third or a display state to display information on a display of the transparent assembly. The transparent display assembly includes a front panel, a rear panel, an outer spacer configured to maintain a first distance between the front panel and the rear panel, a display provided on a rear surface of the front panel, a light guide plate spaced apart from the display, and a first spacer configured to support the light guide plate and to maintain a second distance between the display and the light guide plate.

A controller for a refrigerator for an entrance gate according to an embodiment of the present invention is configured to: register a user authentication means through a user authentication method setting process; and to open an outer door only when user authentication has succeeded, if an article delivery command is input, thereby preventing theft of the article.

A home appliance includes a door sensor; a display; a main processor; a sub-processor configured to control a display operation of the display; and a power control element configured to be connected to the sub-processor, wherein the main processor is configured to: generate a control signal for turning on or off power of the sub-processor based on information sensed by the door sensor, and turn on or off the power of the sub-processor by controlling the power control element according to the control signal.

A portable cooler container is provided. The temperature control system cools a chamber of the container to transport temperature sensitive contents via the container. An electronic display screen on one of the lid and the container body selectively displays an electronic shipping label for the portable cooler container.
