    Abstract

    The present invention provides a display device, which comprises a display panel, a partitioning module, a data transforming module, a scanning driver, and a data driver. The display panel has M pixel units. The partitioning module partitions the M pixel units into N pixel-unit groups and generates at least one partitioning signal. The data transforming module receives at least one original image data of the M pixel units and generates at least one data transforming signal. The data driver receives the at least one data transforming signal, and transfers the at least one data transforming signal to the M pixel units, to light up each of the N pixel-unit groups only for one frame of X frames of an image period. By randomly selecting pixel units to light up, the image flicker problem is solved.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

    [0033] The following description of each embodiment, with reference to the accompanying drawings, is used to exemplify specific embodiments which may be carried out in the present invention. Directional terms mentioned in the present invention, such as “top”, “bottom”, “front”, “back”, “left”, “right”, “inside”, “outside”, “side”, etc., are only used with reference to the orientation of the accompanying drawings. Therefore, the used directional terms are intended to illustrate, but not to limit, the present invention. In the drawings, components having similar structures are denoted by the same numerals.

    [0034] FIG. 4 is a drawing of a display device 300 of the present invention. The display device 300 comprises a display panel 330, a partitioning module 310, a data transforming module 320, a scanning driver 350, and a data driver 340.

    [0035] The display panel 330 comprises M pixel units 331 (for example, 36 (6*6) pixel units are in the preferred embodiment). The partitioning module 310 partitions the M pixel units 331 into N pixel-unit groups (1-3, for example, 3 groups are in the preferred embodiment, a numeral in the pixel unit represents its group) and generates at least one partitioning signal 312. The data transforming module 320 receives at least one original image data 360 of the M pixel units 331 and generates at least one data transforming signal 322. The data driver 340 receives the at least one data transforming signal 322, and transfers the at least one data transforming signal 322 to the M pixel units 331, to light up each of the N pixel-unit groups (1-3) only for one frame of X frames of an image period (in one preferred embodiment, an image period has 3 frames). For example, at the first frame, the first pixel-unit group (1) lights up; at the second frame, the second pixel-unit group (2) lights up; at the third frame, the third pixel-unit group lights up. After actual experiments, while X is equal to N, the image flicker problem has relative improvement.

    [0036] The partitioning module 310 generates the N pixel-unit groups (1-3) according to a random number table. Hence, each group of the N pixel-unit groups (1-3) may not have the same lighting sequence in different image periods (such as two adjacent image periods). For example, in different image periods, the second pixel-unit group (2) of the preferred embodiment can light up at the first frame, the first pixel-unit group (1) of the preferred embodiment can light up at the third frame, and the third pixel-unit group (3) of the preferred embodiment can light up at the second frame. Or, in different image periods, each group of the N pixel-unit groups (1-3) may not have the same pixel units so long as each of the M pixel units 331 light up only once in an image period.

    [0037] Moreover, a pixel unit amount of each of the N pixel-unit groups (1-3) is equal to M divided by N. In the preferred embodiment, M is equal to 36, N is equal to 3, and hence, the pixel unit amount of each of the N pixel-unit groups (1-3) is 12. While M is unable to be evenly divided by N, an approximate integer is fine so long as each of the M pixel units 331 light up only once per image period.

    [0038] In detail, the at least one data transforming signal 322 is generated according to the at least one original image data 360 of the M pixel units 331 and the at least one partitioning signal 312 by using the data transforming module 320.

    [0039] FIG. 5 is a flow diagram of a display method of the present invention. Please kindly refer to FIG. 4 for the numeral of the elements, no description is mentioned again. The method comprises:

    [0040] First, processing a step S01, M pixel units 331 of a display panel 330 are partitioned into N pixel-unit groups (1-3) and at least one partitioning signal 312 is generated by a partitioning module 310; then, processing a step S02, at least one original image data 360 of the M pixel units 331 is received by a data transforming module 320; then, processing a step S03, at least one data transforming signal 322 is generated by the data transforming module 320 according to the at least one original image data 360 of the M pixel units 331 group; then, processing a step S04, the at least one data transforming signal 322 is inputted into a data driver 340; then, processing a step S05, the at least one data transforming signal 322 is inputted to the M pixel units 331 by the data driver 340 and at least one scanning signal is inputted to the M pixel units by a scanning driver 350; finally, processing a step S06, each of the N pixel-unit groups (1-3) lights up sequentially and respectively for one frame of X frames of an image period.

    [0041] After actual experiments, while X is equal to N, the image flicker problem has relative improvement.

    [0042] In the present invention, no change is made to the scanning signal, the technical effect is achieved only with data signal processing.

    [0043] Although the present invention has been disclosed as preferred embodiments, the foregoing preferred embodiments are not intended to limit the present invention. Those of ordinary skill in the art, without departing from the spirit and scope of the present invention, can make various kinds of modifications and variations to the present invention. Therefore, the scope of the claims of the present invention must be defined.
