Using either an iOS or OTG (Android) connection, fan blades are powered by the smart phone connection, providing a cooling breeze that can directed toward an individual. In addition, LEDs are mounted on one of the fan blades and are synchronized to illuminate during fan blade rotation to provide persistence of vision, wherein text images are readable by the human eye. Text messages can be preprogrammed or, in an alternative embodiment, entered directly from the smart phone. ## Claims ### Claim 1 A smart phone fan and LED display comprising: a housing having a lower section and an upper section; a base pivotably coupled to said lower section, said base having a terminal constructed and arranged to fit within a smart phone terminal receptacle, wherein said base is pivotable from about −90 degrees to about +90 degrees, relative to a longitudinal axis of said housing, adapting said housing to be positionable relative to a smart phone; a motor positioned within said housing, said motor electrically coupled to said terminal and constructed to be powered from current received through said terminal when said terminal is connected to said smart phone; a fan assembly electrically coupled to said motor, said fan formed from at least two flexible fan blades, each having a leading edge and a trailing edge capable of moving air when rotated; a plurality of LEDs attached to at least one fan blade and electrically coupled to a controller; a smart phone app for programming said controller with a text message entered by an operator of the smart phone, wherein the smart phone operator is allowed to import, manipulate, store and selectively display an image of the operator's choice as the text image; wherein said text image is displayed by persistence of vision from LEDs during rotation of the fan assembly. ### Claim 2 (depends on 1) The smart phone fan and LED display according to claim 1 wherein said controller is programmed with text messages. ### Claim 3 (depends on 1) The smart phone fan and LED display according to claim 1 wherein said terminal is compatible with a smart phone iOS receptacle. ### Claim 4 (depends on 1) The smart phone fan and LED display according to claim 1 wherein said terminal is compatible with a smart phone USB-OTG Android receptacle. ### Claim 5 (depends on 1) The smart phone fan and LED display according to claim 1 wherein said base is constructed and arranged to be supported by said terminal when said terminal is coupled to said smart phone, and wherein said base is constructed and arranged to support said housing and fan display by said terminal upon connection of said terminal to said smart phone. ### Claim 6 (depends on 1) The smart phone fan and LED display according to claim 1, wherein said base further comprises a terminal adapter having a first end and a second end, said terminal located on said first end of said terminal adapter and said terminal adapter coupling said terminal to said base. ### Claim 7 (depends on 6) The smart phone fan and LED display according to claim 6, wherein said terminal adapter further includes a second terminal located on said second end of said terminal adapter. ### Claim 8 (depends on 7) The smart phone fan and LED display according to claim 7, wherein said terminal adapter further includes a central terminal member electrically coupled on a first end to said terminal and said central terminal member electrically coupled on a second end to said second terminal. ### Claim 9 (depends on 8) The smart phone fan and LED display according to claim 8, wherein said terminal is compatible with a smart phone USB-OTG Android receptacle and said second terminal is compatible with a smart phone iOS receptacle. ### Claim 10 (depends on 9) The smart phone fan and LED display according to claim 9, wherein said base further includes a circuit board, said circuit board electrically coupled to said central terminal member. ### Claim 11 (depends on 10) The smart phone fan and LED display according to claim 10, wherein said central terminal member further includes a plurality of contacts, said contacts electrically coupling said central terminal member to said circuit board. ### Claim 12 (depends on 1) The smart phone fan and LED display according to claim 1 wherein text display is emojis stored on the smart phone. ### Claim 13 (depends on 1) The smart phone fan and LED display according to claim 1 wherein text images are displayed in a plurality of different colors. ### Claim 14 (depends on 1) The smart phone fan and LED display according to claim 1 wherein text images are substantially immovable relative to the smart phone during display thereof. ### Claim 15 (depends on 1) The smart phone fan and LED display according to claim 1 wherein text images are rotating during display.
