Display apparatus and method

摘要

A display apparatus includes: a video processor which performs calibration; a signal generator which generates a signal; and a controller which controls the signal generator to generate an analog signal corresponding to a predetermined direct current voltage when performing the calibration, and controls the video processor to convert the analog signal into the digital signal and to adjust the digital signal to have a same value as a reference value. The signal input for calibration is achieved in a board controllable by a microcomputer, so that the board itself can automatically perform the calibration with regard to various kinds of signals without connection of an external device.
