    Abstract: A display device includes a sensing line and a data driver. The sensing line is in a display panel. The data driver includes a plurality of integrated circuits. Each of the integrated circuits includes an interface, which includes a mobile industry processor interface (MIPI) and a crack detector. The crack detector detects cracks of the panel based on the sensing line and transmits and receives information corresponding to the crack to and from adjacent ones of the integrated circuits using a transmission terminal and a reception terminal in the MIPI.

    Abstract: Systems and methods are described for a display driver integrated circuit that is configured to certify whether an application processor and the display driver integrated circuit are genuine products. The display driver integrated circuit includes: an encryptor for generating first encrypted data by encrypting first data; a data converter for converting the first data into a first converted signal expressed with four or more voltage levels; an interface for providing the first converted signal to a host processor, and receiving, from the host processor, a second converted signal corresponding to second encrypted data generated by the host processor; and a determiner for controlling a display panel by comparing the first encrypted data with converted data corresponding to the second encrypted data. The second converted signal transferred through the interface is expressed with the voltage levels.

    Abstract: A display device includes a display panel having flexibility, a storage connected to a first end of the display panel and accommodating the display panel so that the display panel is inserted and withdrawn, an extension part connected to a second end of the display panel, which is opposite to the first end of the display panel, and facing one side of the storage in a first direction, and a display driving integrated circuit which receives image data and a control signal from a host and provides a data signal to the display panel.
    The display driving integrated circuit includes a data processor which receives a smart size change signal from the host and sets a non-active area of the display panel based on the smart size change signal.
