Patent ID: 8692758

Claim:
A display device of an active matrix type, comprising: a display driver which (i) includes a serial-parallel converter, a source start pulse generating section, and a gate driver control signal generating section and (ii) is configured to receive image data included in serial data by serial transmission, the serial data having a first flag for indicating whether the image data is written into pixels added thereto, the serial-parallel converter configured to extract the first flag and the image data from the serial data in accordance with a timing of a serial clock transmitted through a wire used for the serial transmission but different from a wire for the serial data, in accordance with the timing of the serial clock, the serial-parallel converter configured to generate a timing signal serving as a clock signal for operating a shift register of a data signal line driver included in the display driver, by use of the first flag and the timing signal serving as the clock signal for operating the shift register, the source start pulse generating section is configured to generate a timing signal for an initial horizontal period in one frame period, and input the timing signal for the initial horizontal period to the shift register of the data signal line driver, in a case where a subsequent horizontal period exists, the source start pulse generating section is configured to generate a timing signal for the subsequent horizontal period by use of a signal that is generated by shifting of a timing signal for a horizontal period immediately before the subsequent horizontal period by at least one horizontal display period by the shift register of the data signal line driver, and input the timing signal for the subsequent horizontal period to the shift register of the data signal line driver, by use of the signal that is generated by the shifting by the at least one horizontal display period by the shift register of the data signal line driver, the gate driver control signal generating section is configured to generate a timing signal to be inputted to a shift register of a scanning signal line driver included in the display driver, and in accordance with the timing signals for the initial horizontal period and the subsequent horizontal period, and a scanning signal supplied by the scanning signal line driver, the display device is configured to write the image data into pixels.
