A source driver integrated circuit of the present invention comprises: a sensing circuit for receiving a sensing signal for pixels through a sensing line connected to the pixels, converting the sensing signal so as to generate sensing data, and generating a fault signal if an abnormal signal that exceeds an input range is received from the sensing line; and a data driving circuit for receiving, from the data processing circuit, image data which is processed to be compensated according to the sensing data and a data control signal in which the fault signal is reflected, converting the image data so as to generate data voltage, and controlling supply of the data voltage to the pixels according to the data control signal.

Display device, sensing circuit and source driver integrated circuit

Disclosed is a display driving device that supports accurate correction of the characteristics of pixels by reflecting the characteristics of a source driver in realtime. The display driving device may include: a sensing circuit configured to sense pixel signals for correcting characteristics of pixels of a display panel and sense at least one reference signal for correcting characteristics of a source driver when sensing the pixel signals; and an analog digital converter configured to convert the pixel signals and the at least one reference signal sensed by the sensing circuit into pixel data and reference data, and to transmit the pixel data and the reference data.

Display driving device

Disclosed are a display device and a panel compensation method of the display device. The panel compensation method of the display device includes a step of allowing at least one line pixel of a display panel to be a current source that generates a pixel current with the same value, and a step of correcting a deviation between all current sensing paths of a source driver by using the pixel current with the same value and correcting a characteristic deviation between all pixels after correcting the deviation between the current sensing paths.

Display device and panel compensation method thereof

Disclosed are a display device, and a source driver and a packet recognition method thereof. In the display device, when check information of a control data packet of transmitted transmission data is normal, a control data packet of to be restored is updated with a control data packet of a current cycle, and when the check information is abnormal, the control data packet to be restored is maintained, so that it is possible to normally drive a source signal even through there is an error or a change in the control data packet.
