Patent ID: 8170358

Claim:
An image processing method for driving a display panel with a display driver, the method comprising: obtaining a least significant bit (LSB) associated with a pixel block from the display panel, wherein the LSB is a 2 -bit number, the pixel block comprises 4×4 pixels which are (1, 1), (1, 2), (1, 3), (1, 4), (2, 1), (2, 2), (2, 3), (2, 4), (3, 1), (3, 2), (3, 3), (3, 4), (4, 1), (4, 2), (4, 3), and (4, 4), respectively; reducing two bits from a bit number of each of the pixels of the pixel block; determining whether to carry each of the pixels or not according to the LSB; carrying the pixels (1, 1), (1, 3), (3, 1), and (3, 3) of the pixel block and remaining the rest pixels of the pixel block non-carried in a first frame, carrying the pixels (1, 4), (2, 2), (3, 4), and (4, 2) of the pixel block and remaining the rest pixels of the pixel block non-carried in a second frame, carrying the pixels (2, 1), (2, 3), (4, 1), and (4, 3) of the pixel block and remaining the rest pixels of the pixel block non-carried in a third frame, and carrying the pixels (1, 2), (2, 4), (3, 2), and (4, 4) of the pixel block and remaining the rest pixels of the pixel block non-carried in a fourth frame, when the LSB is 01 ; and remaining the pixels (1, 1), (1, 3), (3, 1), and (3, 3) of the pixel block non-carried and carrying the rest pixels of the pixel block in the first frame, remaining the pixels (1, 4), (2, 2), (3, 4), and (4, 2) of the pixel block non-carried and carrying the rest pixels of the pixel block in the second frame, remaining the pixels (2, 1), (2, 3), (4, 1), and (4, 3) of the pixel block non-carried and carrying the rest pixels of the pixel block in the third frame, and remaining the pixels (1, 2), (2, 4), (3, 2), and (4, 4) of the pixel block non-carried and carrying the rest pixels of the pixel block in the fourth frame, when the LSB is 11.
