Abstract: A display method is applied to a display apparatus including a display panel, a display driver chip, and a microprocessor. The display method includes outputting, by the display panel, a scanning-done signal of a first frame image generated after scanning rows of pixel circuits of the display panel; after the microprocessor or the display driver chip receives the scanning-done signal, writing, by the display driver chip, initial data of a second frame image provided by the microprocessor and outputting, by the display driver chip, display data of the second frame image to the display panel based on the initial data; or outputting, by the display driver chip, the display data of the second frame image to the display panel in response to the scanning-done signal, the display data being generated based on the initial data provided by the microprocessor. The second frame image follows the first frame image.

Abstract: A system includes a controller and a detector. The controller is configured to read servo spirals written on a magnetic surface of a disk drive. The servo spirals are written on the magnetic surface of the disk drive based on seed wedges. The seed wedges are written on the magnetic surface of the disk drive prior to writing the servo spirals on the magnetic surface of the disk drive. The controller is configured to write a servo pattern on the magnetic surface of the disk drive based on reading the servo spirals written on the magnetic surface of the disk drive. The detector is configured to detect, while reading the servo spiral written on the magnetic surface of the disk drive, interference caused by the seed wedges written on the magnetic surface of the disk drive.
