Description

Source driving device and method for driving display panel

technical field

The present invention relates to a driving device of an electronic component and a driving method thereof, and in particular to a source driving device of a display panel and a driving method thereof.

Background technique

Please refer to Figure 1 and Figure 2. FIG. 1 shows the polarity distribution of a plurality of pixels showing dot inversion on a known display panel 10, and FIG. 2 shows the driving channels used to drive the second line of pixels in FIG. 1. Schematic diagram of the waveform of the output driving voltage. In this example, each pixel will have a coupling effect on the common electrode voltage Vcom (common voltage) during charging and discharging, and as a result, the common electrode voltage Vcom will be shifted to different degrees. For example, according to the distribution of the polarities of the pixels in FIG. 1 , the combined effect of the driving voltages output by each driving channel will cause the common electrode voltage Vcom to shift upward. When the common electrode voltage Vcom deviates too much, it will cause poor image display such as flickering or crosstalk on the display panel.

In order to improve the above poor display situation, the known technology has developed a variable dot inversion driving method. FIG. 3 shows the polarity distribution of a plurality of pixels showing variable dot inversion on the known display panel 20. FIG. 4 shows the driving signals output by each driving channel when used to drive the second row of pixels in FIG. 3. Schematic diagram of the voltage waveform. In this example, the pixels on the display panel 20 exhibit a horizontal-2-dot inversion polarity distribution. From the waveform of the driving voltage in FIG. 4 , it can be known that the coupling effect of each pixel on the common electrode voltage Vcom will cancel each other during charging and discharging, so the common electrode voltage Vcom will not shift, thereby improving the poor display of the picture.

However, in the related example of horizontal two-dot inversion, although this driving method can improve the poor picture display, its effect is limited to reducing the offset caused by part of the display pattern to the common electrode voltage Vcom. For some display patterns, driving the display panel by means of horizontal two-dot inversion still cannot effectively improve the poor image display.

Detailed ways

FIG. 5 is a schematic diagram of a source driver device for driving a display panel according to an embodiment of the present invention. FIG. 6 is a flow chart showing the steps of a driving method of a display panel according to an embodiment of the present invention. Please refer to FIG. 5 and FIG. 6 , the source driving device 100 of this embodiment is used to drive the display panel 200 . The source driving device 100 includes a data operation circuit 110 and a pixel driving circuit 120 . The pixel driving circuit 120 is coupled to the data operation circuit 110 . The data operation circuit 110 is used to receive the pixel data Sp1 (step S200 ), and perform a polarity determination operation on the pixel data Sp to determine the polarity distribution information Sp2 of the plurality of pixels 210 on the display panel 200 (step S210 ). In this embodiment, the way of determining the polarity is, for example, subtracting the grayscale value of the pixel data of the next row (line) from the grayscale value of the pixel data of the previous row in the same drive channel to determine the polarity of the next row. The polarity of the pixel. Next, the pixel driving circuit 120 drives the display panel 200 according to the pixel data Sp1 and the polarity distribution information Sp2 (step S220 ). It should be noted that in this embodiment, for the sake of brief description, FIG. 5 only shows 4 rows of pixels and 12 drive channels on the display panel 200 for illustration, but those skilled in the art should know the number And the polarity distribution of the pixels are not intended to limit the present invention.

Therefore, in this embodiment, the polarity distribution of the plurality of pixels 210 on the display panel 200 is dynamically determined by the data operation circuit 110 of the source driver 100 according to the actual image displayed by the display panel 200 . That is to say, the source driving device 100 can dynamically adjust the magnitude of the coupling effect generated by each pixel on the common electrode voltage during charging and discharging, so as to reduce the offset of the common electrode voltage, thereby improving the poor display of the picture caused thereby. , to provide good display quality.

Specifically, FIG. 7 shows the polarity distribution of multiple pixels showing variable dot inversion on the display panel 300 of a related example of the present invention. Schematic diagram of the waveform of the driving voltage output by each driving channel. Please refer to FIG. 7 and FIG. 8. The polarity distribution of the pixels on the display panel 300 in FIG. 7 is the same as that in FIG. In FIG. 3 , the display pattern of the display panel 20 is that the column pixels (column pixels) driven by the drive channels R1, B1, G2, R3, B3, and G4 display the brightest gray scale with a gray scale value of 255, and the drive channels G1, The columns of pixels driven by R2 , B2 , G3 , R4 , and B4 display the darkest gray scale with a gray scale value of 0. Here, the display pattern of the display panel 20 is defined as the second display pattern. In FIG. 7, the display pattern of the display panel 300 is that the column pixels driven by the drive channels R1, G2, and B3 display the brightest gray scale with a gray scale value of 255, and the drive channels G1, B1, R2, B2, R3, G3, The columns of pixels driven by R4 , G4 , and B4 display the darkest gray scale with a gray scale value of 0. Here, the display pattern of the display panel 300 is defined as the second display pattern. It can be seen from the waveform of the driving voltage in FIG. 8 that the combined effect of the driving voltage output by each driving channel will cause the common electrode voltage Vcom to shift upward. Therefore, for the second display pattern, if the display panel 300 is driven by the horizontal two-dot inversion method, the common electrode voltage Vcom will still shift upwards, which cannot effectively improve the poor image display.

FIG. 9 shows the polarity distribution of a plurality of pixels driven by adaptive dot inversion on the display panel 400 according to an embodiment of the present invention. FIG. 10 shows the conditions of each driving channel for driving the second row of pixels in FIG. 9 Schematic diagram of the waveform of the output driving voltage. Please refer to FIG. 9 and FIG. 10 , in FIG. 9 , the pattern displayed on the display panel 400 is the same as that displayed on the display panel 300 , and both are the second display pattern. In this embodiment, the distribution of pixel polarities on the display panel 400 is dynamically determined by the data operation circuit 110 in FIG. 5 according to the second display pattern, for example. Furthermore, the pixel driving circuit 120 drives the display panel 400 according to the determined polarity distribution information Sp2. Therefore, the polarity distribution of the pixels is shown in Figure 9, which is based on the horizontal two-point inversion, but the polarity distribution of the column pixels driven by the drive channels G2 and B2 is adaptively dynamic according to the second display pattern Adjustment. Therefore, from the waveform of the driving voltage in Figure 10, it can be seen that the coupling effect of each pixel on the common electrode voltage Vcom will cancel each other during charging and discharging, so the common electrode voltage Vcom will not shift, thereby improving the poor display of the screen. .

Generally speaking, the common driving mode of polarity inversion includes the driving mode of single-line inversion (1-line inversion) in addition to the above-mentioned dot inversion and horizontal two-dot inversion. The driving method of the display panel of the present invention is also applicable to the situation of dynamically adjusting the polarity distribution of single-line inversion of panel pixels.

FIG. 11 shows the polarity distribution of multiple pixels driven by adaptive single-line inversion on the display panel 500 according to another embodiment of the present invention. FIG. 12 shows the driving channels used to drive the second row of pixels in FIG. 11 Schematic diagram of the waveform of the output driving voltage. Please refer to FIG. 11 and FIG. 12 , taking the second display pattern displayed on the display panel 500 as an example, the data operation circuit 110 will perform a polarity determination operation on the pixel data Sp to determine the polarity of a plurality of pixels 510 on the display panel 500 Distribution information Sp2. Next, the pixel driving circuit 120 drives the display panel 500 according to the pixel data Sp1 and the polarity distribution information Sp2. Therefore, the polarity distribution of the pixels on the display panel 500 is based on the single-line inversion as shown in FIG. The pattern has been adjusted adaptively.

The following describes the influence of the third display pattern of an arbitrary random frame on the offset of the common electrode voltage Vcom under different polarity inversion driving methods, and the application of the driving method of the display panel of the present invention will reduce this influence .

FIG. 13 and FIG. 15 respectively illustrate the polarity distribution of multiple pixels on the display panels 600 and 700 of the two related examples of the present invention, and FIG. 14 and FIG. 16 respectively illustrate the methods used to drive the second row of pixels in FIG. 13 and FIG. 15 Schematic diagram of the waveform of the driving voltage output by each driving channel at the same time. Please refer to FIG. 13 to FIG. 16 , the display panel 600 is driven by dot inversion, and the display panel 600 is driven by horizontal two-dot inversion. In these two examples, when the display panels 600 and 700 display the third display pattern, each pixel will have a coupling effect on the common electrode voltage Vcom during charging and discharging, and the result will cause a considerable shift in the common electrode voltage Vcom , as shown in FIG. 14 and FIG. 16 respectively, wherein the common electrode voltage Vcom of the display panel 600 shifts upward more than that of the display panel 700 .

FIG. 17 shows the polarity distribution of multiple pixels driven by adaptive polarity inversion on a display panel 800 according to another embodiment of the present invention. Schematic diagram of the waveform of the driving voltage output by the channel. Please refer to FIG. 17 and FIG. 18 , in FIG. 17 , the pattern displayed on the display panel 800 is the same as that displayed on the display panels 600 and 700 , and both are third display patterns. In this embodiment, the distribution of pixel polarities on the display panel 800 is dynamically determined by the data operation circuit 110 in FIG. 5 according to a random third display pattern, for example. Furthermore, the pixel driving circuit 120 drives the display panel 800 according to the determined polarity distribution information Sp2. Therefore, the polarity distribution of the pixels is shown in FIG. 17 , and the polarity distribution of each pixel on the display panel 800 is adaptively and dynamically adjusted according to the third display pattern. Therefore, it can be seen from the waveform of the driving voltage in Figure 18 that the coupling effect caused by each pixel to the common electrode voltage Vcom will cancel each other during charging and discharging, which can reduce the degree of offset of the common electrode voltage Vcom, thereby improving the poor display of the screen. situation.

Please refer to FIG. 5 and FIG. 6 again. In this exemplary embodiment, the data operation circuit 110 sequentially performs a polarity determination operation on the pixel data of the entire row of pixels in each row of pixels, so as to determine the polarity distribution information of the plurality of pixels 210 on the display panel 200 . For example, the data operation circuit 110 of this embodiment firstly performs a polarity determination operation on the pixel data of the entire row of pixels in the first row, so as to determine the polarity distribution of the pixels in the entire row of the first row. Next, the data operation circuit 110 of this embodiment performs a polarity determination operation on the pixel data of the entire second row of pixels to determine the polarity distribution of the second entire row of pixels. Afterwards, the data operation circuit 110 will follow this rule to sequentially perform polarity determination operations on the entire row of pixel data in the next row, so as to determine the polarity distribution information of all pixels on the display panel 200 .

In the present invention, the data operation circuit 110 may also sequentially perform polarity determination operations on the pixel data of at least some pixels in each row of pixels to determine the polarity distribution information of at least some pixels on the display panel, which is specifically described as follows.

FIG. 19 is a flow chart showing the steps of a driving method of a display panel according to another embodiment of the present invention. Please refer to FIG. 5 and FIG. 19 , in step S300 , the data operation circuit 110 sequentially performs a polarity determination operation on the pixel data of at least some pixels in each row of pixels to determine the polarity distribution information of at least some pixels on the display panel 200 . Taking the first row of pixels as an example, the data operation circuit 110, for example, first performs a polarity determination operation on the pixel data of the pixels driven by the driving channels R1, G1, B1, R2, G2, and B2 in the first row of pixels, so as to Determines the polarity of the pixels.

Next, in step S310 , the data operation circuit 110 determines whether the pixel data of the entire row of pixels in each row of pixels has been received after performing polarity determination operation on at least a part of pixels in each row of pixels. That is to say, after the polarity determination operation is performed on the pixel data of the pixels driven by the driving channels R1, G1, B1, R2, G2, B2, the data operation circuit 110 will determine other remaining pixels in the first row of pixels, That is, whether the pixel data of the pixels driven by the driving channels R3, G3, B3, R4, G4, and B4 has been received.

Afterwards, in step S320, if the pixel data of the entire row of pixels in each row of pixels has been received, and the polarity distribution information of the entire row of pixels in each row of pixels has been determined, the pixel driving circuit 120 will be based on the pixel data Sp1 and the polarity distribution information Sp2 is used to drive the display panel 200 . In other words, if the pixel data of the pixels driven by the driving channels R3, G3, B3, R4, G4, and B4 have been received and the polarity distribution information of these pixels has been determined, the pixel driving circuit 120 will Sp1 and polarity distribution information Sp2 are used to drive the first row of pixels of the display panel 200 .

Next, in step S330, the data operation circuit 110 and the pixel driving circuit 120 will repeatedly execute steps S300, S310, and S320 to determine the polarity of each pixel row by row until the polarity distribution information of all pixels on the display panel 200 is determined. . Afterwards, the pixel driving circuit 120 drives the display panel 200 according to the pixel data Sp1 and the polarity distribution information Sp2.

On the other hand, in step S340, if the pixel data of the entire row of pixels in each row of pixels has not been received yet, the data operation circuit 110 will continue to receive the pixel data of another part of pixels in each row of pixels, and the pixel data of another part of pixels in each row of pixels The data is subjected to a polarity determination operation to determine the polarity distribution information of another part of the pixels on the display panel. For example, if the pixel data of the pixels driven by the driven channels R3, G3, B3, R4, G4, B4 in the first row of pixels has not been completely received, the data operation circuit 110 will continue to receive the pixel data driven by the driven channels R3, G3, The pixel data of the pixels driven by B3, R4, G4, and B4, and the polarity determination operation is performed on the pixel data of the pixels driven by the driven channels R3, G3, B3, R4, G4, and B4 to determine the first row of pixels The polarity of these pixels in the middle determines the polarity distribution information of the entire row of pixels in the first row of pixels.

The driving methods disclosed in FIG. 6 and FIG. 19 are illustrated by exemplifying that the polarities of all the pixels on the display panel 200 are adaptively adjusted dynamically, but the present invention is not limited thereto. In another embodiment, the driving method of the present invention can only adaptively and dynamically adjust the polarities of some pixels on the display panel 200, while other pixels are driven with preset polarity distribution information. as follows.

FIG. 20 is a flow chart showing the steps of a driving method of a display panel according to another embodiment of the present invention. Please refer to FIG. 5 and FIG. 20 , in step S400 , the data operation circuit 110 first determines that the first part of pixels on the display panel 200 are driven by a specific first polarity distribution information. The first polarity distribution information is, for example, a preset polarity driving method, including frame inversion, column inversion, line inversion and dot inversion one of them. The first polarity distribution information does not undergo adaptive dynamic adjustment according to the image display pattern, and is determined, for example, by an external circuit of the source driving device 100 . Here, the first part of pixels includes, for example, a plurality of pixels driven by the driving channels R3 , G3 , B3 , R4 , G4 , and B4 .

Next, in step S410 , the data operation circuit 110 sequentially performs a polarity determination operation on the pixel data of the second part of pixels in each row of pixels to determine the second polarity distribution information of the second part of pixels on the display panel 200 . Here, the second part of pixels includes, for example, a plurality of pixels driven by the driving channels R1 , G1 , B1 , R2 , G2 , and B2 . Therefore, in this step, the data operation circuit 110 will adaptively and dynamically adjust the second polarity distribution information according to the screen display pattern. It should be noted that in this step, the manner of determining the second polarity distribution information can be determined by referring to the driving method in FIG. 6 or FIG. 19 , and will not be repeated here.

After that, in step S420 , the pixel driving circuit 120 drives a plurality of pixels on the display panel 200 according to the pixel data Sp1 and the combined first and second polarity distribution information Sp2 .

To sum up, in the exemplary embodiment of the present invention, the source driver uses the driving method to adaptively and dynamically adjust the polarity distribution of the pixels on the display panel. Through this driving method, the coupling effect caused by each pixel to the common electrode voltage will cancel each other during charging and discharging, which can reduce the degree of common electrode voltage offset, thereby improving the poor display of the picture.
