Abstract:
1. A display controller for outputting synthesized image data to a display module which includes: a display part in which sub-pixels connected to data lines via switching devices controlled by scanning lines are arranged in n-rows and m-columns (m and n are natural numbers), which is driven by (n+1) pieces of data lines and (m+1) pieces of the scanning lines; and an image separating device which directs light emitted from the sub-pixels towards a plurality of viewpoints in an extending direction of the data lines in a sub-pixel unit; the display controller comprising: an image memory which stores viewpoint image data for the plurality of viewpoints; a writing control device which writes the viewpoint image data inputted from outside to the image memory; and a readout control device which reads out the viewpoint image data from the image memory according to a readout order corresponding to the display module, and outputs the readout data to the display module as the synthesized image data, wherein the readout order corresponding to the display module is a readout order that is obtained from a repeating regulation that is determined based on a positional relation between the image separating device and the display part as well as layout of the sub-pixels, number of colors, and layout of the colors, wherein: the display part is formed by having an up-and-down sub-pixel pair that is formed with two of the sub-pixels arranged by sandwiching one data line as a basic unit; the switching devices provided respectively to the two sub-pixels are connected in common to the data line sandwiched by the two sub-pixels, and are controlled by different scanning lines from each other; and the up-and-down sub-pixel pairs neighboring to each other in the extending direction of the data lines are so disposed that the switching devices thereof are connected to the different data lines from each other, and wherein: the number of colors of the sub-pixels are three colors of a first color, a second color, and a third color; provided that “y” is a natural number, one of the colors of two sub-pixels of the up-and-down sub-pixel pair connected to y-th data line is the first color and the other color is the second color, the pair forming either an even-numbered column or an odd-numbered column of the display part; one of the colors of two sub-pixels of the up-and-down sub-pixel pair connected to (y+1)-th data line is the second color and the other color is the third color, the pair forming the other one of the even-numbered column or the odd-numbered column of the display part; one of the colors of two sub-pixels of the up-and-down sub-pixel pair connected to (y+2)-th data line is the third color and the other color is the first color, the pair forming either an even-numbered column or an odd-numbered column of the display part; one of the colors of two sub-pixels of the up-and-down sub-pixel pair connected to (y+3)-th data line is the first color and the other color is the second color, the pair forming the other one of the even-numbered column or the odd-numbered column of the display part; one of the colors of two sub-pixels of the up-and-down sub-pixel pair connected to (y+4)-th data line is the second color and the other color is the third color, the pair forming either an even-numbered column or an odd-numbered column of the display part; one of the colors of two sub-pixels of the up-and-down sub-pixel pair connected to (y+5)-th data line is the third color and the other color is the first color, the pair forming the other one of the even-numbered column or the odd-numbered column of the display part; and in a following readout order from the image memory, the readout control device: reads out the first color and the second color by corresponding to the y-th data line, and reads out a viewpoint image which corresponds to one of the even-numbered column or the odd-numbered column of the display part; reads out the second color and the third color by corresponding to the (y+1)-th data line, and reads out a viewpoint image which corresponds to the other one of the even-numbered column or the odd-numbered column of the display part; reads out the third color and the first color by corresponding to the (y+2)-th data line, and reads out a viewpoint image which corresponds to one of the even-numbered column or the odd-numbered column of the display part; reads out the first color and the second color by corresponding to the (y+3)-th data line, and reads out a viewpoint image which corresponds to the other one of the even-numbered column or the odd-numbered column of the display part; reads out the second color and the third color by corresponding to the (y+4)-th data line, and reads out a viewpoint image which corresponds to one of the even-numbered column or the odd-numbered column of the display part; reads out the third color and the first color by corresponding to the (y+5)-th data line, and reads out a viewpoint image which corresponds to the other one of the even-numbered column or the odd-numbered column of the display part.
