Abstract:
1. A method of driving a 3D image display device, comprising: receiving a 3D data frame and separating the 3D data frame into a left-eye data frame and a right-eye data frame; doubling the left-eye data frame into the original left-eye data frame and a copied left-eye data frame and doubling the right-eye data frame into the original right-eye data frame and a copied right-eye data frame; ODC (over driving control) modulating the original left-eye data frame to a first modulated left-eye data frame based on the copied right-eye data frame arranged prior to the original left-eye data frame, ODC modulating the copied left-eye data frame to a second modulated left-eye data frame based on the original left-eye data frame arranged prior to the copied left-eye data frame, ODC modulating the original right-eye data frame to a first modulated right-eye data frame based on the copied left-eye data frame arranged prior to the original right-eye data frame, and ODC modulating the copied right-eye data frame to a second modulated right-eye data frame based on the original right-eye data frame arranged prior to the copied right-eye data frame; substituting the second modulated left-eye data frame and the second modulated right-eye data frame with black frames, wherein the ODC modulating includes respectively comparing each of the original left-eye data frame, the copied left-eye data frame, the original right-eye data frame, and the copied right-eye data frame with the corresponding prior data frames, detecting a data variation according to the result of each respective comparing step, and reading a compensation value corresponding to each respective data variation from a memory, and wherein the substituting of the second modulated left-eye data frame and the second modulated right-eye data frame with black frames is only performed after the ODC modulating of each of the original left-eye data frame, the copied left-eye data frame, the original right-eye data frame, and the copied right-eye data frame; and displaying data of final modulated frames consisting of the first modulated left-eye data frame, the first modulated right-eye data frame and the black frames on a display panel, wherein a flag bit is generated as a first logic in synchronization with the display timings of the original left-eye data frame and the original right-eye data frame, and the flag bit is generated as a second logic in synchronization with the display timings of the copied left-eye data frame and the copied right-eye data frame, wherein, in the substitution step, the first modulated left-eye data frame and the first modulated right-eye data frame are not substituted with black frames according to the first logic of the flag bit, and the second modulated left-eye data frame and the second modulated right-eye data frame are substituted with black frames according to the second logic of the flag bit, and wherein the logic of the flag bit is used in the step of substituting the second modulated left-eye data frame and the second modulated right-eye data frame with black frames after the ODC modulating of the original left-eye data frame, the copied left-eye data frame, the original right-eye data frame, and the copied right-eye data frame.
