BRIEF DESCRIPTION OF THE DRAWINGS

To describe the technical solutions of the present disclosure more clearly, the accompanying drawings of the embodiments will be briefly introduced below. It is to be known that the accompanying drawings in the following description merely involve with some embodiments of the present disclosure, but not limit the present disclosure. In the drawings:

FIG. 1 illustrates a schematic structural diagram of a display panel according to an embodiment of the present disclosure;

FIG. 2 illustrates a schematic diagram of example illustrating borrowing a subpixel according to an embodiment of the present disclosure; and

FIG. 3 illustrates a flowchart of a method for driving a display panel according to an embodiment of the present disclosure.

DETAILED DESCRIPTION

To make the technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are merely some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments without creative efforts shall fall within the scope of the present disclosure.

Specific implementations of the display panel and the drive method thereof, and the display device provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

Large-sized display devices have larger load because they have larger screens. It is difficult to drive the entire display panel by one drive circuit (for example, implemented by a driver IC), and thus a plurality of drive circuits may be employed to drive the large-sized display device. In addition, for improving high-resolution display quality, an algorithm module configured to perform subpixel borrowing may be arranged in the drive circuit, so as to implement subpixel borrowing by borrowing between adjacent pixels.

Subpixel borrowing is typically implemented by borrowing pixels forward or backward through the pixels. When being driven by one drive circuit, the last subpixel column cannot borrow the next subpixel column. Therefore, when the drive circuit drives the last subpixel column of the display panel, the subpixel borrowing cannot be completed. In this case, the problem of occurrence of abnormal bright lines in the last column may be caused. A small-sized display screen only needs to be driven by one drive circuit, and the bright lines in the last column do not have a significant effect on the entire display. However, in the case that a plurality of drive circuits are spliced to drive a large-sized display screen, when a bright line occurs if it is impossible to implement subpixel borrowing at the joint of two adjacent drive circuits, a bright line may occur in a central region of the display screen, which may seriously have a negative effect on the display effect.

FIG. 1 illustrates a schematic structural diagram of a display panel 100 according to an embodiment of the present disclosure. As shown in FIG. 1, the display panel may include a plurality of sets of pixel columns, for example, a first set of pixel columns L, a second set of pixel columns M, and a third set of pixel columns N, etc. Each of the sets of pixel columns may include a plurality of subpixel columns. FIG. 1 schematically illustrates a first subpixel column L₁, . . . , a penultimate subpixel column L_n−1 and a last subpixel column L_n in the first set of pixel columns L, a first subpixel column M₁, . . . , a penultimate subpixel column M_n−1 and a last subpixel column M_n in the second set of pixel columns M, and a first subpixel column N₁, . . . , a penultimate subpixel column N_n−1 and a last subpixel column N_n in the third set of pixel columns N. Each of the subpixel columns may include a plurality of subpixel units. Each of the subpixel units may include at least two subpixels configured to display different colors.

The display panel may further include a plurality of drive circuits, which may correspond to the plurality of sets of pixel columns respectively and may drive the respective sets of pixel columns to display. As shown in FIG. 1, the plurality of drive circuits may include a first drive circuit D1 configured to drive the first set of pixel columns L, a second drive circuit D2 configured to drive the second set of pixel columns M, and a third drive circuit D3 configured to drive the third set of pixel columns N.

Specifically, the drive circuit may send a source data signal for the subpixel column in the set of pixel columns of the drive circuit which is adjacent to the set of pixel columns of an adjacent drive circuit to the adjacent drive circuit. For example, the second drive circuit D2 may send the source data signal for the first subpixel column M₁ in the second set of pixel columns M to the first drive circuit D1 which is adjacent to the first subpixel column M₁. In addition, for example, the second drive circuit D2 may also send the source data signal for the last subpixel column M_n to the third drive circuit D3 which is adjacent to the last subpixel column M_n.

In addition, the drive circuit may also receive, from an adjacent drive circuit, a source data signal for the subpixel column in the set of pixel columns of the adjacent drive circuit which is adjacent to the set of pixel columns of the drive circuit, and generate a data signal for driving the subpixel column in the set of pixel columns of the drive circuit which is adjacent to the set of pixel columns of the adjacent drive circuit, based on the received source data signal. For example, the second drive circuit D2 may receive, from the first drive circuit D1, a source data signal for the last subpixel column L_n in the first set of pixel columns L, and generate a data signal for driving the first subpixel column M₁ in the second set of pixel columns M, based on the received source data signal. In addition, for example, the second drive circuit D2 also may receive, from the third drive circuit D3, a source data signal for the first subpixel column N₁ in the third set of pixel columns N, and generate a data signal for driving the last subpixel column M_n in the second set of pixel columns M, based on the received source data signal.

Those skilled in the art may understand that only three sets of pixel columns are schematically illustrated in this embodiment, but the number of sets of pixel columns should not be limited. According to this embodiment of the present disclosure, the display panel may include two or more sets of pixel columns.

In the display panel provided by the embodiment of the present disclosure, by way of data communication between the two drive circuits for driving adjacent sets of pixel columns, the source data signals for two adjacent subpixel columns at a joint of the two adjacent set of subpixel columns are respectively transmitted to the corresponding adjacent drive circuits, such that subpixel borrowing at the joint can be implemented. In this way, it is avoided occurrence of abnormal bright lines in a central region when the same display panel is illuminated by a plurality of drive circuits.

The data communication between two drive circuits for driving the adjacent sets of pixel columns is further described in the following embodiments.

In some embodiments of the present disclosure, the drive circuit may send, when driving the last subpixel column in the set of pixel columns of the drive circuit, the source data signal for the last subpixel column to the next adjacent drive circuit. For example, the second drive circuit D2 may send, when driving the last subpixel column M_n in the second set of pixel columns M, the source data signal for the last subpixel column M_n to the third drive circuit.

In another embodiment, the drive circuit also may receive, when the last subpixel column in the set of pixel columns of the previous adjacent drive circuit is being driven, a source data signal for the last subpixel column in the set of pixel columns of the previous drive circuit from the previous adjacent drive circuit, and generate a data signal for driving the first subpixel column in the set of pixel columns of the drive circuit based on the received source data signal. For example, when the last subpixel column L_n in the first set of pixel columns L of the first drive circuit D1 is being driven, the second drive circuit D2 may receive, from the first drive circuit D1, a source data signal for the last subpixel column L_n in the first set of pixel columns L, and generate a data signal for driving the first subpixel column M₁ in the second set of pixel columns M based on the received source data signal.

In some embodiments of the present disclosure, when driving the penultimate subpixel column in the set of pixel columns of the drive circuit, the drive circuit may receive, from the next adjacent drive circuit, a source data signal for the first subpixel column in the set of pixel columns of the next adjacent drive circuit, and generate a data signal for driving the last subpixel column in the set of pixel columns of the drive circuit based on the received source data signal. For example, when driving the penultimate subpixel column M_n−1 in the second set of pixel columns M, the second drive circuit D2 may receive, from the third drive circuit D3, a source data signal for the first subpixel column N₁ in the third set of pixel columns N, and generate a data signal for driving the last subpixel column M_n in the second set of pixel columns M, based on the received source data signal.

In another embodiment, when the penultimate subpixel column in the set of pixel columns of the previous adjacent drive circuit is being driven, the drive circuit may also send a source data signal for the first subpixel column in the set of pixel columns of the drive circuit to the previous adjacent drive circuit. For example, when the penultimate subpixel column L_n−1 in the first set of pixel columns L of the first drive circuit D1 is being driven, the second drive circuit D2 may send a source data signal for the first subpixel column M₁ in the second set of pixel columns M to the first drive circuit D1.

FIG. 1 also schematically illustrates a pixel arrangement of the display panel. Each of the subpixel units in one of the adjacent subpixel columns includes a red subpixel and a green subpixel (for example, represented by RG), and each of the subpixel units in the other one of the adjacent subpixel columns includes a blue subpixel and a green subpixel (for example, represented by BG). The subpixel unit BG borrows a red subpixel R of the adjacent subpixel unit to form a RGB pixel. The subpixel unit RG borrows a blue subpixel B of the adjacent subpixel unit to form the RGB pixel. It is to be noted that the above pixel arrangement is only for illustration, and the above disclosure concept provided by some embodiments of the present disclosure may be applied to other display panels that satisfy pixel arrangement for borrowing subpixels, which is not limited herein.

The specific implementation process of a subpixel borrowing algorithm is to implement pixel combination by borrowing subpixels of adjacent subpixel unit. For example, the source data signal actually inputted by a system side into the drive circuit to perform subpixel borrowing is RGBRGB . . . . However, the pixel arrangement of the display panel is RGBGRGBG . . . as shown in FIG. 1, and thus the subpixel unit BG borrows R of a next subpixel unit to form a RGB pixel, and the subpixel unit RG borrows B of the next subpixel unit to form the RGB pixel. FIG. 2 illustrates a mapping mode in subpixel borrowing. As shown in FIG. 2, the inputted R11 and R12 are mapped to the display panel to form R11′, by way of data communication and borrowing algorithm. G11 is mapped to the display panel to form G11′, by way of data communication and borrowing algorithm. B11 and B12 are mapped to the display panel to form B11′, by way of data communication and borrowing algorithm. G12 is mapped to the display panel to form G12′, by way of data communication and borrowing algorithm. By analogy, borrowing of subpixels is implemented, wherein a specific algorithm formula thereof is as below:R′_ni=(((R_ni)^2.2+(R_n(i+1))^2.2)/2)^1/2.2;G′_ni=G_ni;B′_ni=(((B_ni)^2.2+(Bn_(i+1))^2.2)/2)^1/2.2; andG′_n(i+1)=G_n(i+1);

wherein n=1, 2, 3, 4, 5, 6 . . . , which represents a row number, i=1, 2, 3, 4, 5, 6 . . . , which represents a serial number of the pixel column in which the subpixel unit is positioned, R, G and B represent source data signals received by the drive circuit, and R′, G′, B′ represent data signals used by the drive circuit to drive the subpixel unit to display. The above formula is for a pixel arrangement of BGRG . . . . Different pixel arrangements have subtle differences in algorithm formula, but their basic ideas of borrowing do not change, and thus are not described in detail herein.

In some embodiments of the present disclosure, the drive circuit may further include at least one serial communication interface. The source data signal is transmitted between the drive circuits adjacent to each other via the serial communication interface. For example, the drive circuit may send, via the serial communication interface, a source data signal for the first subpixel column in the set of pixel columns of the drive circuit to the previous adjacent drive circuit.

In some embodiments of the present disclosure, the drive circuit may further include a line buffer. The line buffer may store the source data signal received via the serial communication interface. Specifically, two adjacent drive circuits may implement data communication via the serial communication interface, and may store, via the line buffer, the source data signal transmitted by the serial communication interface. Borrowing a subpixel at a joint may be implemented by using the source data signal received via the serial communication interface. When borrowing the subpixel, the data signal stored in the line buffer may be invoked.

As mentioned above, the display panel according to some embodiments of the present disclosure may prevent occurrence of bright lines in a central region of a display screen when the display panel is driven by a plurality of drive circuits to display.

In another aspect, an embodiment of the present disclosure also provides a method for driving a display panel, which is described in detail below.

In some other embodiments, when the last subpixel column in the set of pixel columns of the previous adjacent drive circuit is being driven, the drive circuit may receive, from the previous adjacent drive circuit, a source data signal for the last subpixel column in the set of pixel columns of the previous drive circuit, and generate a data signal for driving the first subpixel column in the set of pixel columns of the drive circuit based on the received source data signal.

As mentioned above, by way of data communication between two adjacent drive circuits, source data signals of two adjacent subpixel columns at a joint can be respectively transmitted to the corresponding drive circuit to perform subpixel borrowing at the joint, thereby driving the subpixel unit at the joint to display. In this way, borrowing a subpixel unit may be implemented at the joint of the two adjacent drive circuit, thereby solving the problem of occurrence of abnormal bright lines in a central region when the display panel is illuminated by a plurality of drive circuits.
