Abstract
A display apparatus including a display panel and a driver circuit is provided. The display panel includes a display region and a non-display region. The non-display region includes a plurality of dummy pixels connected to one another. The driver circuit provides gate driving voltages and a test data voltage, so as to make the dummy pixels connected to one another generate a charging rate test signal in response to the test data voltage.
