A display device and method of operation that provides self-generated power. The device includes: a display portion including a plurality of pixels; a data driver applying a data signal to data lines connected to the plurality of pixels; a signal controller transmitting an image data signal for generation of the data signal to the data driver; a power supply generating a driving voltage for operation of the signal controller and the data driver; a thermoelectric generation portion generating electrical energy by using heat generated by at least one of the signal controller, the power supply, and the data driver; and a converter generating an auxiliary driving voltage that is the same as the driving voltage by using the electrical energy.

A method of mounting an electronic device includes: preparing a printed circuit board including a base substrate, connection pads disposed on the base substrate and spaced apart from each other, and a solder resist including contact holes exposing a portion of the connection pads; disposing preliminary bumps on the exposed portion of the connection pads via the contact holes; disposing under-fill patterns in areas between the preliminary bumps on the solder resist; disposing an electronic device on the preliminary bumps and the under-fill patterns; and mounting the electronic device onto the printed circuit board by reflowing the preliminary bumps and the under-fill patterns. The disposing of the under-fill patterns may include: providing an under-fill film including a base film having openings spaced apart from each other, and the under-fill patterns disposed within the openings; applying pressure to the under-fill film; and removing the base film from the under-fill film.
