Abstract:
1. A display panel drive device comprising: a parallel-to-serial converter for conducting parallel-to-serial conversion on an input signal and outputting a serial signal; a transmission section for converting the serial signal output from the parallel-to-serial converter to a signal complying with a differential serial transmission system and transferring a signal via a transmission line; a reception section for receiving the signal transferred via the transmission line; a serial-to-parallel converter for conducting serial-to-parallel conversion on the signal received by the reception section and outputting a parallel signal; and a drive pulse output section for generating a drive pulse to drive a display panel based on the parallel signal output by the serial-to-parallel converter; a display control section for controlling display on a display panel; a drive section for driving the display panel based on a signal supplied from the display control section; and a data transfer device for transferring data between the display control section and the drive section, wherein the display control section comprises a storage section for storing address data, a readout section for reading out address data stored in the storage section, and a shift clock generation section for generating a shift clock, the drive section comprises a shift register for successively storing the address data based on the shift clock, a latch circuit for latching the address data stored in the shift register, and a drive circuit for driving the display panel based on the address data output from the latch circuit, the input signal comprises the address data and the shift clock, the data transfer device comprises the parallel-to-serial converter and the transmission section, and the drive section comprises the reception section and the serial-to-parallel converter.
