Patent ID: 11069270

Abstract:
In a control circuit 500, a data transmission circuit 503 transmits image data Dp, and a code generation circuit 511 generates a first code CDa from the image data Dp. In a data line drive circuit 200, which is a drive signal generation circuit, a data reception circuit 201 receives the image data Dp, a code generation circuit 203 generates a second code CDb from the image data Dp, and a code transmission circuit 204 transmits the generated code as a code CDc. In the control circuit 500, a code reception circuit 512 receives the code CDc and outputs the received code CDc as the second code CDd, a comparison circuit 521 of an error detection circuit 520 detects an error in the image data DP received data line drive circuit 200 based on the first code CDa and the second code CDd.
