The invention discloses a portable product information
display device making use of
solar energy. The portable product information
display device comprises a shell, a
solar cell panel, a storage battery, a
voltage-stabilizing device, a controller, a
signal receiver and a display, wherein the
solar cell panel and the display are embedded in the outer surface of the shell; the storage battery, the
voltage-stabilizing device, the controller and the
signal receiver are arranged in the shell; the
solar cell panel is connected to the storage battery and the controller by virtue of the
voltage-stabilizing device; the storage battery is electrically connected to the controller, the
signal receiver and the display; the storage battery is used for supplying power to the controller, the signal receiver and the display; and the controller is in signal connection to the signal receiver and the display. The
display device disclosed by the invention, which takes the
solar energy as an
energy source, can display product information in real time, so that a platform is established for spreading the product information; therefore, a bridging effect is taken on product information flowing.
