Description of Related Art
Generally, in an arranging method for pixels in the conventional display panel, one data line is usually located between the pixels of the same row. The data line is configured to connect a driving circuit to a plurality of pixels, and write display data into the pixels when the pixels are turned on, so as to drive the display panel. A gate driving circuit can sequentially apply scan signals on scan lines so that a source driving circuit can utilize the scan lines to charge the pixels in order to write the display data into the pixels. Accordingly, when a screen resolution and a screen update frequency of the display panel are confirmed, a time for the gate driving circuit to sequentially turn on rows of the pixels may then be obtained. With increases in the screen resolution and the screen update frequency of the display panel, a time for the rows of the pixels to be turned on is shorten, which means that a time for the source driving circuit to charge the pixels is also shorten. In a circumstance where the time for charging the pixels is insufficient, a display quality of the display panel may be affected accordingly.

To make the above features and advantages of the disclosure more comprehensible, several embodiments accompanied with drawings are described in detail as follows.
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
Referring to
In the present embodiment, the pixels P11 to PNM are arranged in an array as shown in
Further, in the present embodiment, in the display panel 100, the data lines S1 to S(P−2) are located between each column of the pixels. The data lines S1 to S(P−2) are respectively coupled to a plurality of pixels located on the same column among the pixels. For example, the data line S1 is located between the first column of the pixels (P11 to P1M) and a second column of the pixels (P21 to P2M), and coupled to the pixels such as a part of the pixels (P12, P15) among the first column of the pixels (P11 to P1M). The data line S2 is also located between the first column of the pixels (P11 to P1M) and the second column of the pixels (P21 to P2M), and coupled to the pixels such as a part of the pixels (P13) among the first column of the pixels (P11 to P1M). The data line S3 is also located between the first column of the pixels (P11 to P1M) and the second column of the pixels (P21 to P2M), and coupled to the pixels such as a part of the pixels (P22, P25) among the second column of the pixels (P21 to P2M). In another embodiment, based on actual design requirements, the data line S1 and the data line S2 may also be coupled to different parts of the pixels among the second column of the pixels (P21 to P2M), and the data line S3 may also be coupled to a different part of the pixels among the first column of the pixels (P11 to P1M), which are not particularly limited in the invention.
In the present embodiment, the data lines S0 to SP are grouped into a plurality of data line groups A1 to AN. In the present embodiment, each of the data line groups A1 to AN includes three or more data lines among the data lines S0 to SP. For example, the data line group A1 includes the data lines S1 to S3. Among them, the data line group AN includes, for example, the data lines S0, S(P−1), SP. The data line groups A1 to A(N−1) are respectively located between the pixels on the same row. For example, the data lines S1 to S3 are located between the first column of the pixels (P11 to P1M) and the second column of the pixels (P21 to P2M). The data lines S0 to SP are configured to write display data into the pixels when the pixels are turned on.
In the present embodiment, each of the scan lines G1 to GM is coupled to all of the pixels located on the same row among the pixels P11 to PNM. For example, because the scan line G1 is coupled to the first row of the pixels (P11 to PN1), when the scan signal of the scan line G1 is at a high level, the pixels P11 to PN1 located on the same row are turned on at the same time. Connecting relations between the scan lines G2 to GM and each of the pixels are as shown in
Furthermore, in the present embodiment, each of the data line groups A1 to AN includes three data lines. In correspondence to an amount of the data lines included in each of the data line groups A1 to AN, the scan lines G1 to GM are grouped into a plurality of scan line groups B1 to BY, wherein Y is a positive integer greater than 1. Each of the scan line groups B1 to BY includes three scan lines among the scan lines G1 to GM. As shown in
In other words, in the present embodiment, an amount of the data lines included in each of data line groups A1 to AN is equal to an amount of the scan lines included in each of the scan line groups B1 to BY. For example, in the present embodiment, because each of the data line groups A1 to AN includes three data lines among the data lines S0 to SP, each of the scan line groups B1 to BY includes three scan lines as the corresponding amount. That is to say, the scan line group B1 includes the scan lines G1 to G3. Each one of the three scan lines included in each of the scan line groups B1 to BY is configured to correspondingly turn on all of the pixels located on the same row. For example, the scan lines G1 to G3 included in the scan line group B1 are configured to correspondingly turn on the pixels P11 to PN1, the pixels P12 to PN2 and the pixels P13 to PN3.
It should be noted that, the scan line groups in the exemplary embodiment of the invention are not limited to only include adjacent scan lines. In an embodiment, the scan line group can also include any three scan lines among all of the scan lines. For example, the scan line group B1 can also include the scan lines G1, G2 and G4. In other words, in the scan line group B1, one of the scan lines (G4) is not adjacent to the other scan lines (G1, G2). Within the same driving timing sequence, the scan signals of the scan lines G1, G2 and G4 are in the high level state at the same time. In an embodiment, the scan line group B1 can also include the scan lines G1, G4 and G7. In other words, in the scan line group B1, the three of the scan lines G1, G4 and G7 are not adjacent to one another. Within the same driving timing sequence, the scan signals of the scan lines G1, G4 and G7 are in the high level state at the same time. That is to say, in an embodiment of the invention, for the scan lines of the same scan line group, the scan signals are in the high level state at the same time within the same driving timing sequence. It should be noted that, the scan lines included in the scan line group is decided and adjusted in accordance with a coupling relation of the data line group and the pixels.
Take the data line group A2 as another example, in the present embodiment, the data line group A2 is located between the column of the pixels (P21 to P23) and the column of the pixels (P31 to P33). The data line S5 is coupled to the pixel P21, the data line S4 is coupled to the pixel P23, and the data line S6 is coupled to the pixel P33. In view of the above, in at least a part of the data line groups, a part of the pixels among the pixels in which the display data is written by the data lines is located on the same column. In other embodiments, in at least a part of the data line groups, at least one pixel among the pixels in which the display data is written by the data lines and other pixels among the pixels in which the display data is written by the data lines are not located on the same column. Take the present embodiment for example, among the pixels P21 to P23 and P31 to P33 on the two sides of the data line group A2, the pixel P12 and the pixel P23 are located on the same column, but the pixel P31 and said two pixels are not located on the same column.
In the present embodiment, in at least a part of the data line groups, a part of the pixels among the pixels in which the display data is written by the data lines is located on the same row. In other words, in the data line group A1, a part of the pixels among the pixels P12, P13 and P22 in which the display data is written by the data lines S1 to S3 is located on the same row, namely, the pixels P12 and P22 are located on the same row. Further, in the present embodiment, in at least a part of the data line groups, all of the pixels among the pixels in which the display data is written by the data lines are not located on the same row. Take the data line group A3 for example, among the pixels P31, P32 and P43 in which the display data is written by the data lines S7 to S9, the pixels P31, P32 and P43 are not located on the same row.

Specifically, in the present embodiment, the display panel 200 includes a plurality of scan lines G1 to GM, a plurality of data lines S0 to SQ and a plurality of pixels P11 to PNM, wherein M, N, Q are positive integers greater than 1. The pixels P11 to PNM are arranged in an array as shown in
In the present embodiment, the data lines S0 to SQ are grouped into a plurality of data line groups A1 to AN, wherein X is a positive integer greater than 1. In the present embodiment, each of the data line groups A1 to AN includes four data lines among the data lines S0 to SQ. For example, the data line group A1 includes the data lines S2 to S5. Among them, the data line group AN includes, for example, the data lines S0, S1, S(Q−1), SQ. The data line groups A1 to A(N−1) are respectively located between the pixels on the same row. For example, the data lines S2 to S5 are located between the first column of the pixels (P11 to P1M) and the second column of the pixels (P21 to P2M). The data lines S0 to SQ are configured to write display data into the pixels when the pixels are turned on.
In the present embodiment, each of the scan lines G1 to GM is coupled to all of the pixels located on the same row among the pixels P11 to PNM. For example, because the scan line G1 is coupled to the first row of the pixels (P11 to PN1), when the scan signal of the scan line G1 is at a high level, the pixels P11 to PN1 located on the same row are turned on at the same time. Connecting relations between the scan lines G2 to GM and each of the pixels are as shown in
Furthermore, in the present embodiment, each of the data line groups A1 to AN includes four data lines. In correspondence with an amount of the data lines included in each of the data line groups A1 to AN, the scan lines G1 to GM are grouped into a plurality of scan line groups B1 to BZ, wherein Z is a positive integer greater than 1. Each of the scan line groups B1 to BZ includes four scan lines among the scan lines G1 to GM. As shown in
In other words, in the present embodiment, an amount of the data lines included in each of data line groups A1 to AN is equal to an amount of the scan lines included in each of the scan line groups B1 to BZ. For example, in the present embodiment, because each of the data line groups A1 to AN includes four data lines among the data lines S0 to SQ, each of the scan line groups B1 to BZ includes four scan lines as the corresponding amount. That is to say, the scan line group B1 includes the scan lines G1 to G4. Each one of the four scan lines included in each of the scan line groups B1 to BZ is configured to correspondingly turn on all of the pixels located on the same row. For example, the scan lines G1 to G4 included in the scan line group B1 are configured to correspondingly turn on the pixels P11 to PN1, the pixels P12 to PN2, the pixels P13 to PN3, and the pixels P14 to PN4.
