As shown in FIGS. 4 to 6, the present disclosure further provides a display device including a display panel 200 and a control chip 100 electrically connected to the display panel. The control chip is configured to drive the display panel to display an image according to the method(s) for driving a display panel as described above.


As shown in FIG. 1, a system chip/mainboard/control chip (System on Chip, SoC) 100 receives a video source signal (first video signal) of 4K2K@60 Hz (4K2K is the image resolution, 4K is the number of columns in the image resolution, 2K is the number of rows in the image resolution, and 60 Hz is the first frame rate), and the control chip 100 processes the video source signal into a second video signal of 4K1K@120 Hz (4K1K is the image resolution, 1K is the number of rows in the image resolution, and 120 Hz is the second frame rate), and the display panel 200 changes a refresh frequency from 60 Hz to 120 Hz, and displays an image of 4K2K@120 Hz (4K2K is the resolution, and 120 Hz is the second frame rate) according to the second video signal.


The control chip 100 splits any one frame of the first image data (F) in the first video signal having an image resolution of 4K2K into two frames of the second image data having an image resolution of 4K1K, namely, odd-numbered row sub-image data (FA) and even-numbered row sub-image data (FB).


Wherein the odd-numbered row sub-image data (FA) is image data of all odd-numbered rows in the first image data (F). The even-numbered row sub-image data (FB) is image data of all even-numbered rows in the first image data (F).


The control chip 100 controls the scan driver 230 of the display panel to turn on or off sub-pixels in odd-numbered rows and sub-pixels in even-numbered rows by means of drive mode of interlaced scanning, and writes the odd-numbered row sub-image data (FA) and the even-numbered row sub-image data (FB) into corresponding sub-pixels in the odd-numbered rows and corresponding sub-pixels in the even-numbered rows via the data driver 220 (see FIG. 6), respectively. Finally, the display panel displays the image data (F) 200 as an image of 4K2K@120 Hz.


The control chip 100 controls the scan driver 230 to realize the drive mode of interlaced scanning through a start control signal (STV) and clock signals CK1-CK8. The control chip 100 sequentially outputs pulses of the start control signal, the clock signal CK1, the clock signal CK3, the clock signal CK5, and the clock signal CK7, controls the scan driver 230 to sequentially turn on the corresponding sub-pixels in the odd-numbered rows, and controls the data driver to write the odd-numbered row sub-image data (FA) into the corresponding sub-pixels in the odd-numbered rows in a drive cycle of the odd-numbered row sub-image data. The control chip 100 sequentially outputs pulses of the start control signal, the clock signal CK2, the clock signal CK4, the clock signal CK6, and the clock signal CK8, controls the scan driver 230 to sequentially turn on the corresponding sub-pixels in the even-numbered rows, and controls the data driver to write the even-numbered row sub-image data (FB) into the corresponding sub-pixels in the even-numbered rows in a drive cycle of the even-numbered row sub-image data.


Wherein, there is an interval called blanking time (BT) between the drive cycle of the odd-numbered row sub-image data and the drive cycle of the even-numbered row sub-image data. A pulse width of the start control signal may be 5H.


In the drive cycle of the odd-numbered row sub-image data, a pulse rising edge of the start control signal is 2H earlier than a pulse rising edge of the clock signal CK1, the pulse rising edge of the clock signal CK1 is 1H earlier than a pulse rising edge of the clock signal CK3, the pulse rising edge of the clock signal CK3 is 1H earlier than a pulse rising edge of the clock signal CK5, and the pulse rising edge of the clock signal CK5 is 1H earlier than a pulse rising edge of the clock signal CK7. Wherein, His a unit time that may be adjusted according to the refresh frequency of the display panel.


In the drive cycle of the even-numbered row sub-image data, the pulse rising edge of the start control signal is 2H earlier than a pulse rising edge of the clock signal CK2, the pulse rising edge of the clock signal CK2 is 1H earlier than a pulse rising edge of the clock signal CK4, the pulse rising edge of the clock signal CK4 is 1H earlier than a pulse rising edge of the clock signal CK6, and the pulse rising edge of the clock signal CK6 is 1H earlier than a pulse rising edge of the clock signal CK8.


As shown in FIG. 3, in the 60 Hz refresh frequency mode, the solution in which the control chip 100 controls the display panel to display an image in a drive mode of progressive scanning is as follows: First, a first frame of first image data (F1) is displayed, and then a second frame of the first image data (F2) is displayed. Wherein, taking an image in which grey surrounds white as an example, the white square moves to the right over time, for example, the position of the white square in the second frame of image (F2) is further to the right than the position in the first frame of the first image data (F1). Wherein, pulse widths and intervals between pulses may be seen in FIG. 2.


In the 120 Hz refresh frequency mode (frequency multiplication), the solution in which the control chip 100 controls the display panel to display an image in a drive mode of interlaced scanning is as follows: Each original frame of first image data is split into odd-numbered row sub-image data and even-numbered row sub-image data. For example, a first frame image (F1) is split into a first odd-numbered row frame image (F11) corresponding to a first odd-numbered row sub-image data and a first even-numbered row frame image (F12) corresponding to a first even-numbered row sub-image data, and a second frame image (F2) is split into a second odd-numbered row frame image (F21) corresponding to a second odd-numbered row sub-image data and a second even-numbered row frame image (F22) corresponding to a second even-numbered row sub-image data.


As shown in FIGS. 4-6, the control chip 100 splits each frame of the first image data into one odd-numbered row sub-image data and one even-numbered row sub-image data, and controls the data driver to output the odd-numbered row sub-image data and the even-numbered row sub-image data of each frame of the first image data in a predetermined order. The predetermined order may be an order of odd-numbered row sub-image data, even-numbered row sub-image data, even-numbered row sub-image data, and odd-numbered row sub-image data in sequence. Of course, the predetermined order may also be an order of the even-numbered row sub-image data, the odd-numbered row sub-image data, the odd-numbered row sub-image data, and the even-numbered row sub-image data in sequence. The display panel 200 displays according to the order in which the odd-numbered row sub-image data and the even-numbered row sub-image data are output from the control chip 100. Therefore, it is possible to avoid a regularly staggered superposition phenomenon caused by the display panel displaying according to a fixed order of odd-numbered row sub-image data, even-numbered row sub-image data, odd-numbered row sub-image data, and even-numbered row sub-image data under a drive mode of interlaced scanning, thereby improving the phenomenon of fishbone-shaped misalignment occurring in the display technology of interlaced scanning under a frequency multiplication mode.


The odd-numbered row sub-image data is a set of image data of a number of odd-numbered rows in a frame of the first image data, and the even-numbered row sub-image data is a set of image data of a number of even-numbered rows in a frame of the first image data. This can be achieved by splitting the odd-numbered row image data and the even-numbered row image data in a frame of image data.


The present disclosure can avoid a regularly staggered superposition phenomenon caused by the display panel displaying according to a fixed order of odd-numbered row sub-image data, even-numbered row sub-image data, odd-numbered row sub-image data, and even-numbered row sub-image data under a drive mode of interlaced scanning by adjusting multiple frames of second image data that are continuously displayed (including at least two frames of odd-numbered row sub-image data and two frames of even-numbered row sub-image data), thereby improving the phenomenon of fishbone-shaped misalignment occurring in the display technology of interlaced scanning under a frequency multiplication mode.


Specifically, the present disclosure overcomes the problem that the display panel needs to wait for half a frame time to start displaying the next frame of odd-numbered row sub-image data after displaying the current frame of even-numbered row sub-image data, resulting in the phenomenon that two screens are interlaced and superimposed on the display panel, namely the fishbone-shaped misalignment phenomenon (as shown in the position circled by the ellipse (dashed line) in FIG. 3).


Wherein, at the 120 Hz refresh frequency, the half a frame time is about 8.4 ms.


As shown in FIG. 6, the display panel 200 includes a pixel array 210 including sub-pixels in odd-numbered rows and sub-pixels in even-numbered rows that are arranged alternately, a data driver 220, and a scan driver 230. The scan driver 230 controls odd-numbered row sub-image data and even-numbered row sub-image data to be written to corresponding sub-pixels in the odd-numbered rows and corresponding sub-pixels in the even-numbered rows, respectively, by a drive mode of interlaced scanning.


As shown in FIG. 5, the scan driver 230 may implement the drive mode of interlaced scanning under the control of a start control signal (STV) and clock signals CK1-CK8.


In a drive cycle of first odd-numbered row sub-image data, the control chip 100 sequentially outputs pulses of the start control signal, the clock signal CK1, the clock signal CK3, the clock signal CK5, and the clock signal CK7, controls the scan driver 230 to sequentially turn on the corresponding sub-pixels in the odd-numbered rows, and controls the data driver to write the first odd-numbered row sub-image data into the corresponding sub-pixels in the odd-numbered rows.


In a drive cycle of first even-numbered row sub-image data, the control chip 100 sequentially outputs pulses of the start control signal, the clock signal CK2, the clock signal CK4, the clock signal CK6, and the clock signal CK8, controls the scan driver 230 to sequentially turn on the corresponding sub-pixels in the even-numbered rows, and controls the data driver to write the first even-numbered row sub-image data into the corresponding sub-pixels in the even-numbered rows.


In a drive cycle of second even-numbered row sub-image data, the control chip 100 sequentially outputs pulses of the start control signal, the clock signal CK2, the clock signal CK4, the clock signal CK6, and the clock signal CK8, controls the scan driver 230 to sequentially turn on the corresponding sub-pixels in the even-numbered rows, and controls the data driver to write the second even-numbered row sub-image data into the corresponding sub-pixels in the even-numbered rows.
