Embodiment 1
[0025]FIG. 4 is a schematic diagram of subfield allocation in Embodiment 1. As shown in FIG. In Embodiment 1, the first subfield and the second subfield of two adjacent frames of data are selected for processing, that is to say, M=2, N=2. The unprocessed subfield is normally displayed according to the input data in the same way as the traditional driving method. The data of the first subfield and the second subfield to be processed need to be processed, and the display positions in these two frames are also adjusted. Adjustment. As shown in Figure 4, in the driving method of embodiment 1, the first frame only displays the third, fourth, ..., eighth subfields of the input signal, as the first, second, ..., sixth subfields of the first frame, due to the input The data of the subfields has not changed, so the weight ratio between the subfields is still 4:8:16:32:64:128. At this time, the original data of the first subfield and the second subfield are temporarily stored and proc...
Embodiment 2
[0028] FIG. 6 is a schematic diagram of subfield allocation in Embodiment 2. As shown in FIG. In Embodiment 2, the first subfield with the lowest weight of the three adjacent frames of data is selected for processing, that is, M is equal to 3, and N is equal to 1. Similar to the method in Embodiment 1, the unprocessed data is normally displayed according to the input data as in the traditional driving method, and the data of the first subfield, the second subfield, and the third subfield that need to be processed need to be processed. The display position in the frame has also been adjusted. As shown in Figure 6, in the driving method of embodiment 2, the first frame and the second frame only display the second, third,..., eight subfields of the input signal, and these seven subfields are used as the first frame and the second frame For the first, second, ... seventh subfields, since the input data does not change, the ratio of each subfield is still 2:4:8:16:32:64:128. At t...
Embodiment 3
[0030] FIG. 7 is a schematic diagram of subfield allocation in Embodiment 3. As shown in FIG. Embodiment 3 is similar to Embodiment 1, and processes data of three subfields with low weights of images of two adjacent frames, that is to say, M is equal to 2, and N is equal to 3. The first frame image displays five high-weight subfields according to the input image data, and the second frame image first displays six subfields according to the input data processing results of the first and second frame three lower subfields, and the weight of the second frame The upper five subfields are displayed according to the entered data. That is to say, the weight ratio of the five subfields in the first frame is: 8:16:32:64:128. The weight ratios of the eleven subfields of the second frame are: 2 / 9:4 / 9:8 / 9:16 / 9:32 / 9:64 / 9:8:16:32:64:128. The minimum gray level that can be displayed in embodiment 3 is reduced, which is 4.5 times higher than that of the traditional driving method, and finer...
