Abstract
A display apparatus includes a timing controller and a gate-driver on array (GOA) control circuit. The timing controller generates a frame synchronization signal. The GOA control circuit is coupled to the timing controller and includes a scan signal management circuit and a level shifter. The scan signal management circuit generates a scan signal management signal according to the frame synchronization signal, a predetermined panel parameter, and an operation clock signal. The scan signal management circuit includes a storage unit which stores the predetermined panel parameter. The level shifter generates a scan control signal according to the scan signal management signal to control a GOA of a display panel circuit. The GOA generates a gate driving signal to control a vertical scan operation of the display panel circuit.
