Description

Display Panel

This disclosure relates to a display panel.

When connecting pixels on a display panel, an interlace connection is typically used. This means that pixels of the same color in a row are connected to the data lines on either side of the pixel in an alternating pattern. However, because pixels of the same color in a row are connected to the same potential as the pixels on either side of them, this connection method can easily produce alternating light and dark patterns, affecting the viewing experience.

The typical solution is to replace staggered connections with a single data line connecting the entire row of pixels. However, this approach can lead to left-right wiggling patterns. To solve both problems simultaneously, a new connection method is needed.

One technical aspect disclosed herein is a display panel.

According to one embodiment of the present disclosure, a display panel includes a substrate, a first pixel, a second pixel, a third pixel, a fourth pixel, a first data line, a second data line, a third data line, and a fourth data line. The first pixel is located on the substrate. The second pixel is located on the substrate and adjacent to a first side of the first pixel. The third pixel is located on the substrate and adjacent to a second side of the first pixel, with the first side being perpendicular to the second side. The fourth pixel is located on the substrate and adjacent to a first side of the third pixel, with the first side of the third pixel aligned with the first side of the first pixel. The first data line is located on the substrate and adjacent to a third side of the first pixel and is electrically connected to the first pixel, with the third side of the first pixel facing away from the first side of the first pixel. The second data line is located on the substrate between the first and second pixels and is electrically connected to the third pixel. The third data line is located on the substrate between the first and second pixels and is electrically connected to the fourth pixel.

The thin-film transistors electrically connect the first data line to the first pixel, the second data line to the third pixel, the third data line to the fourth pixel, and the fourth data line to the second pixel, respectively. The color filter openings are located on either the left or right side of the thin-film transistors.

In one embodiment of the present disclosure, the display panel further includes a fifth pixel, a sixth pixel, a seventh pixel, an eighth pixel, a fifth data line, a sixth data line, a seventh data line, and an eighth data line. The fifth pixel is located on the substrate and on a first side of the second pixel. The sixth pixel is located on the substrate and on a first side of the fifth pixel. The seventh pixel is located on the substrate and on a second side of the fifth pixel. The eighth pixel is located on the substrate and on a first side of the seventh pixel. The fifth data line is located between the second and fifth pixels and is electrically connected to the fifth pixel. The sixth data line is located between the fifth and sixth pixels and is electrically connected to the seventh pixel. The seventh data line is located between the fifth and sixth pixels and is electrically connected to the eighth pixel. The eighth data line is located on a first side of the sixth pixel and is electrically connected to the sixth pixel. The first data line is electrically connected to the seventh data line.

FIG1 schematically illustrates a display panel 1000 according to an embodiment of the present disclosure. FIG2 illustrates a top view of the display panel 1000 of FIG1. Referring to FIG1 and FIG2, the display panel 1000 includes a substrate 1100, a first pixel 1101, a second pixel 1102, a third pixel 1103, a fourth pixel 1104, a first data line 1201, a second data line 1202, a third data line 1203, and a fourth data line 1204. The first pixel 1101 is located on the substrate 1100. The first pixel 1101 can be, for example, a red light-emitting diode pixel, but the present disclosure is not limited thereto. The second pixel 1102 is located on the substrate 1100 and adjacent to a first side 1101a of the first pixel 1101. Second pixel 1102 can be, for example, a green light-emitting diode pixel, but the present disclosure is not limited thereto. Third pixel 1103 is located on substrate 1100 and adjacent to second side 1101b of first pixel 1101, with first side 1101a perpendicular to second side 1101b. In other words, third pixel 1103 and first pixel 1101 are in the same vertical row. Fourth pixel 1104 is located on substrate 1100 and adjacent to first side 1103a of third pixel 1103, with first side 1103a of third pixel 1103 aligned with first side 1101a of first pixel 1101. First data line 1201 is located on substrate 1100 and adjacent to third side 1101c of first pixel 1101, and is electrically connected to first pixel 1101. Third side 1101c of first pixel 1101 faces away from first side 1101a of first pixel 1101. In this document, "facing away from" a side means the side that is away from and opposite to that side. "First side" refers to the right side of a device, "second side" refers to the bottom side of a device, and "third side" refers to the left side of a device, as previously explained. Second data line 1202 is located on substrate 1100 and between first pixel 1101 and second pixel 1102, and is electrically connected to third pixel 1103. The third data line 1203 is located on the substrate 1100 between the first pixel 1101 and the second pixel 1102 and is electrically connected to the fourth pixel 1104. The fourth data line 1204 is located on the substrate 1100 and adjacent to the first side 1102a of the second pixel 1102 and is electrically connected to the second pixel 1102.

In this embodiment, the first data line 1201 is electrically connected to the third data line 1203, and the second data line 1202 is electrically connected to the fourth data line 1204. In Figure 2, the first data line 1201 and the third data line 1203 are shown electrically connected on the top side of the display panel 1000 (i.e., outside the display area), where no pixels are arranged. However, in practice, the first data line 1201 and the third data line 1203 can also be electrically connected on the other side of the display area (i.e., the bottom side). Furthermore, the second data line 1202 and the fourth data line 1204 can also be electrically connected on the other side of the display area (i.e., the bottom side). The display panel 1000 also includes a plurality of thin-film transistors 1320 and a plurality of color filter openings 1310. In this embodiment, the color filter openings 1310 and the thin-film transistors 1320 are arranged parallel to the direction in which the first data lines 1201 extend. The thin-film transistors 1320 electrically connect the first data line 1201 to the first pixel 1101, the second data line 1202 to the third pixel 1103, the third data line 1203 to the fourth pixel 1104, and the fourth data line 1204 to the second pixel 1102, respectively.

Because first data line 1201 is electrically connected to first pixel 1101, second data line 1202 is electrically connected to third pixel 1103, third data line 1203 is electrically connected to fourth pixel 1104, and fourth data line 1204 is electrically connected to second pixel 1102, pixels in the same row will not be connected to the same data line and will not be at the same potential as adjacent pixels in the row. This solves the problems of wavy lines and bright/dark patterns, improving the viewing experience of display panel 1000.

Figures 3 through 5 illustrate enlarged views of the vicinity of a first pixel 1101 and a second pixel 1102 of a display panel according to various embodiments. Referring to Figure 3 , display panel 1000a includes a first pixel 1101, a second pixel 1102, a first data line 1201, a second data line 1202, a third data line 1203, a fourth data line 1204, a color filter opening 1310, and a thin-film transistor 1320. This embodiment differs from the embodiment shown in FIG. 2 in that the display panel 1000a further includes a thin-film transistor side substrate common electrode layer 1330. This thin-film transistor side substrate common electrode layer 1330 is located between the second data line 1202 and the third data line 1203, and between the first data line 1201 and the fourth data line 1204. In other words, the thin-film transistor side substrate common electrode layer 1330 is located between two adjacent pixels (for example, between the first pixel 1101 and the second pixel 1102), reducing the risk of crosstalk between the two adjacent pixels.

Referring to FIG. 4 , display panel 1000b includes a first pixel 1101, a second pixel 1102, a first data line 1201, a second data line 1202, a third data line 1203, a fourth data line 1204, a color filter layer opening 1310, and a thin-film transistor 1320. This embodiment differs from the embodiment shown in FIG. 2 in that display panel 1000b further includes a transparent common electrode layer 1340. Transparent common electrode layer 1340 is located between the second data line 1202 and the third data line 1203, and between the first data line 1201 and the fourth data line 1204. In other words, transparent common electrode layer 1340 is located between two adjacent pixels (e.g., between the first pixel 1101 and the second pixel 1102).

Referring to FIG. 5 , display panel 1000c includes a first pixel 1101, a second pixel 1102, a first data line 1201, a second data line 1202, a third data line 1203, a fourth data line 1204, a color filter opening 1310a, and a thin-film transistor 1320a. This embodiment differs from the embodiment of FIG. 2 in that, in this embodiment, the color filter opening 1310a of display panel 1000c is located either to the left or to the right of the thin-film transistor 1320a, such that the color filter opening 1310a above two adjacent pixels (e.g., the first pixel 1101 and the second pixel 1102) are adjacent to each other. This design increases the aperture ratio of the display panel 1000c, allowing for a larger effective display area (i.e., pixel area).

The implementation methods of Figures 3 to 5 above can be freely applied to the first pixel 1101 and the second pixel 1102 of the display panel 1000.

FIG6 schematically illustrates a display panel 1000d according to another embodiment of the present disclosure. FIG7 illustrates a top view of the display panel 1000d of FIG6. Referring to FIG6 and FIG7, the display panel 1000d includes a substrate 1100, a first pixel 1101, a second pixel 1102, a third pixel 1103, a fourth pixel 1104, a first data line 1201, a second data line 1202, a third data line 1203, and a fourth data line 1204.

The fifth pixel 1105 is located on the substrate 1100 and on a first side of the second pixel 1102. The sixth pixel 1106 is located on the substrate 1100 and on a first side of the fifth pixel 1105. The seventh pixel 1107 is located on the substrate 1100 and on the second side of the fifth pixel 1105. The eighth pixel 1108 is located on the substrate 1100 and on the first side of the seventh pixel 1107. The ninth pixel 1109 is located on the substrate 1100 and on the first side of the sixth pixel 1106. The tenth pixel 1110 is located on the substrate 1100 and on the first side of the eighth pixel 1108.

An eighth data line 1208 is located on a first side of the sixth pixel 1106 and is electrically connected to the sixth pixel 1106. A ninth data line 1209 is located on the substrate 1100 and between the ninth pixel 1109 and the sixth pixel 1106 and is electrically connected to the ninth pixel 1109. The tenth data line 1210 is located on the substrate 1100 and on the first side of the ninth pixel 1109 and is electrically connected to the tenth pixel 1110. The eleventh data line 1211 is located on the substrate 1100 and between the ninth pixel 1109 and the eleventh pixel 1111 and is electrically connected to the twelfth pixel 1112. The twelfth data line 1212 is located on the substrate 1100 and on the first side of the eleventh pixel 1111. It is electrically connected to the eleventh pixel 1111.
