Description
Technical Field
The present invention relates to the field of display technologies, and in particular, to a driving method of a display panel, a display panel and a display device.
Background
A Frame Rate Control (FRC) method is a type of gray scale display method that uses a plurality of frames, and performs gray scale expression by controlling column voltages for each Frame. The FRC algorithm simulates the effect of one frame of the original image with a plurality of frames of images to display more colors, and the perceived brightness is the accumulation of the plurality of frames due to the visual inertia of human eyes. Theoretically, for example, 6-bit display data simulates the effect of 8-bit video data (6bit → 8bit), and 2-bit data is lost, so that 4 frames are required to simulate the effect of one frame of the original image.
Fig. 1 and 2 show a partial database stored in the timing controller, and each frame rate control Table (FRC Table) in the database may be in the form of a 2 × 2 dither matrix as shown in fig. 1, may also be in the form of a 4 × 4 dither matrix as shown in fig. 2, and may of course be in other forms. When the FRC is turned on, as shown in fig. 3 and 4, due to the introduction of the FRC, pixel data of each row in the FRC Table corresponding to the partial Frame (Frame) output is pulled to the common voltage VCOM, and when the common voltage VCOM is pulled greatly and deviates from the central value, noise is easily generated, and even a color cast phenomenon is generated on the panel.
Since the center of the common voltage VCOM of the Panel is affected by various factors such as temperature, pressure, etc., it cannot be guaranteed that the VCOM setting is always the optimum state. With higher and higher resolutions nowadays, the impact of such pulling on picture quality is also getting worse.
Therefore, how to reduce the pulling of the common voltage VCOM and optimize the display effect when the FRC is introduced is a technical problem that needs to be solved urgently by those skilled in the art.

Detailed Description
The following describes in detail specific embodiments of a display panel driving method, a display panel, and a display device according to embodiments of the present invention with reference to the accompanying drawings.
An embodiment of the present invention provides a driving method of a display panel, as shown in fig. 5, specifically including the following steps:
s501, controlling the number of display frames to be output according to gray scale data and frame rate of a frame of picture to be displayed, and selecting a frame rate control table which corresponds to the gray scale data and is consistent with the number of the display frames from a pre-stored database;
s502, arranging and combining the selected frame rate control tables according to the pulling direction of each row of pixel data in the selected frame rate control tables to the common voltage, so that each row of pixel data in the combined frame rate control tables has no pulling direction to the common voltage;
s503, according to the combined frame rate control table, dividing the area corresponding to the combined frame rate control table in the display panel, and driving the display panel to display the gray scale.
The driving method of the display panel provided in the embodiment of the present invention includes: firstly, controlling the number of display frames to be output according to gray scale data of a frame of picture to be displayed and the frame rate, and selecting a frame rate control table which corresponds to the gray scale data and has the same number with the number of the display frames from a pre-stored database; then, arranging and combining the selected frame rate control tables according to the pulling direction of each row of pixel data in the selected frame rate control tables to the common voltage, so that each row of pixel data in the combined frame rate control tables has no pulling direction to the common voltage; and finally, according to the combined frame rate control table, dividing the area corresponding to the combined frame rate control table in the display panel, and driving the display panel to display the gray scale. The driving method provided by the embodiment of the invention performs optimal arrangement by using the selected frame rate control table combination mode, and can reduce the pulling of the common voltage when frequency control is introduced, thereby reducing the noise caused by pulling, improving the image quality and optimizing the display effect.
In the specific implementation, in step S501, the frame rate control table whose number is consistent with the number of display frames is selected from the pre-stored database according to the gray scale data of one frame of the to-be-displayed frame and the frame rate control frame number to be output, and it can be understood that: assuming that 6-bit display data is needed to dither the effect of 8-bit video data, i.e. 4 frames are needed to simulate the effect of one frame of the original image, at this time, the frame rate control is performed on the number of display frames to be output to be 4, and 4 frame rate control tables need to be selected from the pre-stored database. Of course, it is also applicable to an effect of dithering 10-bit video data with 8-bit display data, an effect of dithering 12-bit video data with 10-bit display data, and the like.
In a specific implementation, in the driving method of the display panel provided in the embodiment of the present invention, the step S502 may be implemented by arranging and combining the selected frequency control tables as follows:
and at least two selected frame rate control tables with opposite pulling directions of the pixel data of each row to the common voltage and/or no pulling direction of the common voltage are arranged and combined.
Specifically, it is assumed that FA, FB, FC, FD represent selected Frame rate control tables, as shown in fig. 6a, the display Frame number output by the Frame rate control is 4, the first Frame1 outputs all selected FAs, the second Frame2 outputs all selected FBs, the third Frame3 outputs all selected FCs, and the fourth Frame4 outputs all selected FDs, and as shown in fig. 6b, each row of pixel data in FA, FB, FC, FD has an upward pulling direction, a downward pulling direction, and no pulling direction, and when there is pulling on a common voltage VCOM, it is easy to cause noise, and even cause color shift phenomenon of the panel. Therefore, the selected FA, FB, FC, FD are arranged and combined, and specifically, two selected frame rate control tables with opposite pulling directions (up or down) to the common voltage and/or with no pulling direction to the common voltage (for example, FA and FB are combined, FC and FD are combined) can be arranged and combined, so that the pixel data in each row in the combined frame rate control table has no pulling direction to the common voltage. Taking fig. 7a as an example, the number of display frames output by the Frame rate control is still 4, the first Frame1 outputs combined FA and FB, the second Frame2 outputs combined FB and FA, the third Frame3 outputs combined FC and FD, and the fourth Frame4 outputs combined FD and FC, but as can be seen from fig. 7b, the Frame rate control table after FA and FB are combined, and the Frame rate control table after FC and FD are combined have no pulling direction of each row of pixel data to the common voltage, so that the noise caused by pulling can be reduced, the image quality can be improved, and the display effect can be optimized.
In practical implementation, in the above-mentioned driving method of the display panel provided by the embodiment of the present invention, the combined frame rate control tables are in the form of m × n dithering matrices, and m and n are both greater than or equal to 2, that is, when performing gray scale display by the frame rate control method, the basic unit of the spatial arrangement of each combined frame rate control table is an m × n dithering matrix including data element values, which means that the combined frame rate control tables are repeatedly applied to pixels by the m × n dithering matrix.
The frame rate control tables may be arranged in the row direction and the column direction in the combined frame rate control table according to the following embodiments:
in a first embodiment, in a specific implementation manner, in the driving method of the display panel according to the embodiment of the present invention, when two selected frame rate control tables are combined, the selected frame rate control tables are alternately arranged in a row direction and a column direction in the combined frame rate control table. Taking fig. 7a as an example, when two selected Frame rate control tables are FA and FB, respectively, that is, when the first Frame1 outputs combined FA and FB, the arrangement manners of FA and FB in the row direction and the column direction are both arranged alternately, for example, the first row is arranged alternately by FA, FB, FA, and FB, and the first column is also arranged alternately by FA, FB, FA, and FB; similarly, the second Frame2, the third Frame3 and the fourth Frame4 are arranged alternately.
In a second implementation manner, in a specific implementation manner, in the driving method of the display panel provided in the embodiment of the present invention, at least two selected frame rate control tables are not repeatedly arranged in a row direction and a column direction in the combined frame rate control table. Taking fig. 8a as an example, when the grouped Frame rate control tables are in the form of 2 × 2 dither matrices and two selected Frame rate control tables are FA and FB, respectively, the Frame rate control table output by the first Frame1 is a combined FA and FB arranged in the row direction and FA and FB in the column direction; in the same process, the Frame rate control tables selected are not repeatedly arranged in the row direction and the column direction in the second Frame2, the third Frame3 and the fourth Frame 4. Taking fig. 8b as an example, when the grouped Frame rate control tables are in a 3 × 4 dither matrix form, and the four selected Frame rate control tables are respectively FA, FB, FC, and FD, the FA, FB, FC, and FD are not repeatedly arranged in the row direction and the column direction in the combined Frame rate control table, for example, the first Frame1 is arranged in a manner of FA, FB, and FC when the first row outputs, and is arranged in a manner of FA, FD, FC, and FB when the first column outputs; in the same process, the Frame rate control tables selected are not repeatedly arranged in the row direction and the column direction in the second Frame2, the third Frame3 and the fourth Frame 4. Taking fig. 8c as an example, when the grouped Frame rate control tables are in the form of 4 × 4 dither matrices, and the four selected Frame rate control tables are respectively FA, FB, FC, and FD, the FA, FB, FC, and FD are not repeatedly arranged in the row direction and the column direction in the combined Frame rate control table, for example, the first Frame1 is arranged in the manner of FA, FB, FC, and FD when the first row outputs, and is arranged in the manner of FA, FB, FC, and FD when the first column outputs; in the same process, the Frame rate control tables selected are not repeatedly arranged in the row direction and the column direction in the second Frame2, the third Frame3 and the fourth Frame 4.
In a specific implementation, in the driving method of the display panel provided in the embodiment of the present invention, the following manner may be adopted to determine the pulling direction of each row of pixel data to the common voltage in the frame rate control table:
if the positive polarity number of the common voltage corresponding to the pixel data of the same low gray scale in each row in the frame rate control table is larger than the negative polarity number, the pulling direction of the common voltage is increased; if the number of positive polarities is smaller than that of negative polarities, the pulling direction of the common voltage is decreased; if the number of positive polarities is equal to the number of negative polarities, there is no pull-in direction to the common voltage.
Specifically, taking fig. 6b as an example, a non-color box represents a gray level N, and a box with a filling color represents a gray level N +1, so that the above-mentioned low gray level is the gray level N, and assuming that it is necessary to determine the pulling direction of the pixel data of each row corresponding to the low bit data "01" in the frame rate control table FA to the common voltage, since the positive polarity number of the common voltage corresponding to the pixel data of the first row of the gray level N is smaller than the negative polarity number, it is determined that the pulling direction of the row to the common voltage is decreased; and judging that the pulling direction of the common voltage of the second row rises because the positive polarity number of the common voltage corresponding to the pixel data of the gray scale N of the second row is greater than the negative polarity number, and so on.
Since the combined frame rate control table is repeatedly applied to the pixels by an m × n dither matrix including data element values, in the embodiment of the present invention, in the driving method of the display panel, the display panel may be driven to perform gray scale display in the following manner:
and selecting a proper data element value in the combined frame rate control table according to the gray scale data of a frame of picture to be displayed, and driving the display panel to display the gray scale according to the selected data element value.

Since the principle of the display panel to solve the problem is similar to the aforementioned driving method of the display panel, the implementation of the display panel can refer to the implementation of the driving method of the display panel, and repeated descriptions are omitted.
Based on the same inventive concept, an embodiment of the present invention further provides a display device, including the display panel provided in the embodiment of the present invention, where the display device may be: any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator and the like. Other essential components of the display device are understood by those skilled in the art, and are not described herein or should not be construed as limiting the invention.
