Abstract
A touch testing apparatus includes: a pogo pad area including input and output test pogo pads respectively connected to input and output test pads disposed in a pad area of a touch detection module; a test touch driver circuit configured to detect compression deviations between the input test pad and the input test pogo pad and between the output test pad and the output test pogo pad, and to correct touch data of the touch detection module based on the detected compression deviations; and a test board on which the test touch driver circuit is mounted, wherein the test board is configured to electrically connect the test touch driver circuit with the input and output test pogo pads.
