Abstract:
1. A display apparatus comprising: a printed circuit board to output a control signal, the printed circuit board having a base substrate, a flip chip on the base substrate and an adhesive member between the base substrate and the flip chip; wherein the flip chip comprises a plurality of first output pads to output the control signal, the first output pads being arranged along an edge of the flip chip and spaced apart from each other by a first interval distance, and a plurality of second output pads formed farther away from the edge of the flip chip than the first output pads and spaced apart from each other by a second interval distance greater than the first interval distance, wherein the first and second output pads are formed on the same layer along a rear face of the flip chip toward the base substrate; a driving circuit to output a driving signal in response to the control signal; and a display panel to display an image in response to the driving signal, the display panel spaced apart from the flip chip, wherein the flip chip further comprises: a plurality of connecting lines to electrically connect the first output pads and the second output pads; a plurality of bumps disposed on the second output pads, the bumps sized smaller than the second output pads and protruding from the second output pads by a predetermined height so that the bumps of the flip chip are connected to the base substrate without soldering; and a plurality of test bumps disposed on the first output pad for testing the flip chip, the test bumps sized smaller than the first output pads.
