Apparatus and method for transferring image data to display driver in a time series format to reduce the number of required input terminals to the driver

DETAILED DESCRIPTION The display driving device of this invention has a display driver for driving a display device by image data to perform a display.
The display driving device includes: a time-series data generating section for arranging division data obtained by dividing the image data in a time-series manner, to generate time-series data; and transmission lines provided between the time-series data generating section and the display driver through which the time-series data is transmitted from the time-series data generating section.
According to another aspect of the invention, the display driving device has a display driver for driving a display device by image data to perform a display.
The display driving device includes: a time-series data generating section for arranging division data obtained by dividing the image data in a time-series manner, to generate time-series data; transmission lines provided between the time-series data generating section and the display driver through which the time-series data is transmitted from the time-series data generating section; and an image data demodulating section provided in the display driver, for receiving the time-series data from the transmission lines and for reconstructing the image data from the time-series data.
In one embodiment of the invention, the image data demodulating section includes: a first flip-flop for receiving an inverted synchronization clock and time-series data and for latching the time-series data at the inverted synchronization clock, to acquire respective lower-bit data of the image data; a second flip-flop for receiving a synchronization clock and the time-series data and for latching the time-series data at the synchronization clock, to acquire respective upper-bit data of the image data; and a third flip-flop for receiving the inverted synchronization clock and the time-series data and for latching the upper-bit data from the second flip-flop at the inverted synchronization clock, to acquire respective upper-bit data of the image data
