DISPLAY DRIVE DEVICE, DISPLAY DRIVE SYSTEM, INTEGRATED CIRCUIT DEVICE, AND DISPLAY DRIVE METHOD

摘要

A display drive device, a display drive system, an integrated circuit device, and a display drive method are provided that can handle a plurality of input signals having different specifications. A display drive device 1 includes an external signal detection unit 10 that measures an external timing signal S1 and generates a detection signal S2, a processing unit 20 that generates an internal timing signal S3 based on the detection signal S2, and a drive control signal generation unit 30 that generates, based on the internal timing signal S3, a drive control signal S4 for displaying image information on a display panel 500. The processing unit 20 has a plurality of specifications, determines, based on the detection signal S2, one of the plurality of specifications to which the external timing signal S1 corresponds, and generates the internal timing signal S3 based on the corresponding specification.
