The present disclosure relates to a pixel sensing circuit in which a test is performed only on selected specific channels among channels of the pixel sensing circuit and the total test time of the pixel sensing circuit and data throughput for the test may be reduced.

Pixel sensing circuit and integrated circuit

Provided a source driver integrated circuit (IC) and a display driving device eliminating an existing input pad and internal wiring of a source driver integrated circuit (IC) for receiving a sensing reference voltage from an external voltage source by allowing the sensing reference voltage for initializing pixels during sensing of the pixels to be generated by an internal voltage source, rather than the external voltage source.

Source driver integrated circuit and display driving device

The present disclosure relates to a data transmission and reception method of a data driving device and a data processing device as well as a data transmission and reception system, and more particularly, to a method and a system in which the data driving device receives an initial configuration value from the data processing device, stores the initial configuration value as a configuration restoration value, and rapidly restore an environment for a high-speed communication by using the stored configuration restoration value when a link between the data processing device and the data driving device is lost so as to reduce a time for restoration.

Data transmission/reception system and data transmission/reception method of data driving device and data processing device

The present embodiment relates to a device for driving pixels arranged on a display panel, and a data driving device according to the present embodiment can transmit image data to a plurality of channel groups by including two or more mapping units for mapping the image data to a channel link or by using one data mapping unit connected to a plurality of multiplexers.

Data driving device for driving pixels arranged on display panel

Disclosed is a driver for a display device, which is improved to stably sense pixels. The driver includes a multiplexer configured to output the sensing signal of a first input stage or second input stage, a first switch configured to switch a connection between an odd channel and the first input stage, a second switch configured to switch a connection between an even channel and the second input stage, and a switching circuit configured to switch a connection between a common power line and the first input stage or the second input stage.
