Abstract
The present invention provides a display apparatus, including: a display panel circuit which includes a panel load line and performs a scanning display operation; and a panel driving circuit. The panel driving circuit determines at least a test phase and a scanning display phase according to a display control signal generated by a timing control circuit, wherein the test phase is a partial time period when the panel driving circuit does not perform the scanning display operation. The panel driving circuit generates a test driving signal on the panel load line, and detects an electronic characteristic of the display panel circuit so as to determine a failure item thereof during the test phase according to a pre-determined test instruction. The panel driving circuit generates a display driving signal on the panel load line for the scanning display operation according to the display control signal during the scanning display phase.
