[0035] Figure 4 is a schematic diagram of a data adjustment device for a liquid crystal display according to the first embodiment of the present invention. Please refer to Figure 4 , the data adjustment device 12 includes adjustment units 21 , 22 and a storage unit 33 . In this embodiment, the storage unit 33 takes a frame buffer (Frame Buffer) as an example for illustration. The storage unit 33 is coupled to the adjustment units 21 , 22 for delaying the adjustment data output by the adjustment unit 21 and providing the adjustment data to the adjustment units 21 , 22 accordingly. More specifically, the storage unit 33 can provide the adjustment data stored in the previous period to the adjustment units 21 and 22, and store the adjustment data output by the adjustment unit 21 in the current period.
[0036] Based on the above, the adjustment unit 21 generates adjustment data for the current period to the storage unit 33 and the adjustment unit 22 according to the adjustmen...

[0057] please refer again Figure 4 The correspondence table used by the adjustment units 21 and 22 in the first embodiment is only an optional embodiment. In other embodiments, those skilled in the art can change the correspondence table used by the adjustment units 21 and 22 according to their needs. For example, when the spirit of the present invention is applied to a slow-speed liquid crystal or a high-frequency processing (120 Hz) liquid crystal display, the advantages of the present invention will be more prominent. Figure 7 It is a schematic diagram comparing the light intensity presented by the second embodiment and the known liquid crystal display. Please refer to Figure 7 , the curve 701 is the output data during each period of this embodiment, and the curve 702 is the light intensity presented by the liquid crystal display of this embodiment. The curve 703 is the known output data of each period, and the curve 704 is the light intensity presented by the known li...

[0066] Those skilled in the art should know that in the known technology, a stronger overdrive method is often used to shorten the response time of the liquid crystal. Afterimage.
[0067] please refer again Figure 4 , in the third embodiment, also by changing the corresponding table of the adjustment units 21, 22, so as to improve the well-known bright afterimage problem, for example Figure 8 It is a schematic diagram of the comparison of the light intensity presented by the third embodiment and the known liquid crystal display. Please refer to Figure 8, the curve 801 is the output data of each period of this embodiment, and the curve 802 is the light intensity presented by the liquid crystal display of this embodiment. The curve 803 is the known output data of each period, and the curve 804 is the light intensity presented by the known liquid crystal display.
[0068] It is worth noting that the gray scales of the input data in the first, second, and third periods in ...
