  • Patent number: 11538436
    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.

  • Patent number: 11527185
    Abstract: A display panel driving apparatus includes an interface, a timing controller, a gate driver, and data driver. The interface includes a data determiner to determine whether or not input image data has a communication error and to process a packet of a data stream of the input image data, even though the input image data has the communication error. The timing controller receives the processed input image data from the interface and generates a data signal, a gate control signal, and a data control signal. The gate driver generates a gate signal based on the gate control signal. The data driver generates a data voltage based on the data control signal and the data signal.
