Abstract:
1. A carry table generating method of a display device for generating N dither carry tables, so as to dither N pixel blocks, wherein the display device comprises a timing controller and a memory, and a size of the pixel block is N×N, N is an integer greater than 1, the carry table generating method comprising: reading a plurality of basic tables from the memory by the timing controller, wherein the basic tables are corresponding to a plurality of basic blocks, the number of the basic blocks is smaller than N, and the size of the basic blocks is smaller than the size of the pixel blocks; executing a first conversion procedure by the timing controller for expanding the size of the basic tables, wherein the step of expanding the size of the basic tables by the first conversion procedure comprises: in the first conversion procedure, expanding the size of the basic blocks by using a combination among the basic blocks or a combination among the basic blocks and a plurality of first extended blocks; executing a second conversion procedure by the timing controller for expanding the number of the basic blocks, wherein the step of expanding the number of the basic blocks by the second conversion procedure comprises: in the second conversion procedure, re-arranging sub-blocks in the basic blocks to form a plurality of second extended blocks; and expanding the number of the basic blocks by using the second extended blocks; and generating the dither carry tables by using the expanded basic blocks through the timing controller.
