Abstract
According to an embodiment, both the high-speed communication and the low-speed communication are performed using a single communication line, thereby reducing limitations on wiring on a PCB and increasing the utilization efficiency of a transmission line.
Claims20
A data driving device that configures a communication circuit for receiving image data before receiving the image data, the data driving device comprising:
- an identification circuit configured to receive a first pattern signal having a first frequency and a second pattern signal having a second frequency different from the first frequency and to distinguish the first pattern signal and the second pattern signal;
- and
- a controlling circuit configured to configure the communication circuit when the first pattern signal is received and to terminate the configuration of the communication circuit when the second pattern signal is received.
A data processing device that prepares transmission of image data in a preparation mode prior to a display mode for transmitting the image data to a data driving device, the data processing device comprising:
- a transmitting circuit configured to transmit a signal, comprising a first pattern signal having a first frequency and a second pattern signal having a second frequency different from the first frequency, to the data driving device,
- wherein the data driving device optimizes configuration of a communication circuit according to the signal, the first pattern signal indicates the start of the signal, and the second pattern signal indicates the end of the signal.
A display device comprising:
- a data processing device configured to transmit an equalizer (EQ) training signal comprising a first pattern signal having a first frequency and a second pattern signal having a second frequency different from the first frequency;
- and
- a data driving device, comprising an equalizer, to receive the first pattern signal and the second pattern signal, to start a test for one configuration of the equalizer when the first pattern signal is identified, and to terminate the test for the one configuration of the equalizer when the second pattern signal is identified.
