Problems solved by technology

[0003] However, when the above-mentioned display device displays a dynamic picture, such as a single horizontal line that moves one pixel unit per frame, as figure 2 As shown, the pixel units of odd rows are driven for display in the first half of the first frame of image output, and a single horizontal line can be displayed at this time, and the pixel units of even rows are driven for display in the second half of the first frame of image output , but at this time, the single horizontal line is located in the first row of pixel units, so there will be no picture display during the second half of the first frame of image output; in the first half of the second frame of image output, the pixel units of odd rows are driven display, but at this time the single horizontal line is located in the second row of pixel units, therefore, there will be no picture display during the first half of the second frame of image output, and the even-numbered row of pixel units will be driven during the second half of the second frame of image output For display, a single horizontal line can be displayed at this time; in the first half of the third frame of image output, the pixel units of odd rows are driven for display, and a single horizontal line can be displayed at this time, and in the second half of the third frame of image output Segment drives the pixel units of even rows for display, but at this time the single horizontal line is located in the third row of pixel units, so there will be no picture display in the second half of the third frame image output; in the first half of the fourth frame image output During the period of time, the pixel units of odd rows are driven for display, but at this time the single horizontal line is located in the pixel unit of the fourth row. Therefore, there will be no picture display during the first half of the fourth frame of image output, and after the fourth frame of image output Drive the pixel units of the even-numbered rows for display in the half-time period, and a single horizontal line can be displayed at this time
like this figure 2 As shown, the time interval between the single horizontal line displayed in the first frame and the single horizontal line displayed in the second frame is relatively far, and the time between the single horizontal line displayed in the second frame and the single horizontal line displayed in the third frame is too close, so that the original The smooth picture has a divided feeling, which makes the dynamic resolution of the display device decrease
