DISPLAY DRIVER INTEGRATED CIRCUIT AND METHOD FOR MONITORING DISPLAY DRIVER INTEGRATED CIRCUIT

摘要

A display driving circuit comprises a signal processing unit, a signal monitoring unit, a multiplexer, a source driver, and a gate driver. The signal processing unit includes a plurality of internal blocks which sequentially process input image signals and generates display data in which input signals are processed. The signal monitoring unit receives read data signals from the internal blocks and generates monitoring data corresponding to one read data signal to be monitored among the read data signals. The multiplexer selects and outputs one of the display data and the monitoring data. The source driver drives source lines of a display panel based on the output of the multiplexer. The gate driver drives gate lines of the display panel.
