Method for transmitting image data to driver of display

#1. Field of Invention

#The present invention relates to a method for transmitting image data. More particularly, the present invention relates to a method for transmitting image data to a driver of a liquid crystal display.

#2. Description of Related Art

#The invention can be more fully understood by reading the following detailed description of the embodiments, with reference made to the accompanying drawings as follows:

#FIG. 1 shows the pixel value waveforms transmitted in a conventional display system;

#FIG. 2 shows the pixel value waveforms when using the method for transmitting the image data according to a first embodiment of the present invention;

#In accordance with one embodiment of the present invention, a method for transmitting image data to a driver of a display is provided, in which the image data include a number of pixel values each represented by a number of bits, and each pixel value is a red, green or blue pixel value. The method includes the steps of sequentially transmitting at least two bits of one of the pixel values during a first period through a data line; and sequentially transmitting at least two bits of another one of the pixel values during a second period after the first period through the data line, in which the order of the last bit transmitted during the first period is the same as that of the first bit transmitted during the second period.

#FIG. 2 shows the pixel value waveforms when using the method for transmitting the image data according to a first embodiment of the present invention. As shown, when each pixel value is represented by six bits, i.e. R[0], R[1], . . . , R[5], the six bits of each pixel value are transmitted through three of the data lines. During the first period, the six bits of the first pixel value are sequentially transmitted through three of the data lines, respectively; that is, R[0] and R[1] are sequentially transmitted through one of the data lines, R[2] and R[3] are sequentially transmitted through another one of the data lines, and R[4] and R[5] are sequentially transmitted through yet another one of the data lines.

#During the second period after the first period, the six bits of the second pixel value are sequentially transmitted through the data lines as well, in which the order of the last bit transmitted during the first period is the same as that of the first bit transmitted during the second period; that is, R[1] and R[0] are sequentially transmitted through one of the data lines, R[3] and R[2] are sequentially transmitted through another one of the data lines, and R[5] and R[4] are sequentially transmitted through yet another one of the data lines.
