It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present invention and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
As shown in fig. 1, the pixel structure 800 of the present invention includes a substrate 100, two adjacent first data lines 210 and second data lines 220, two adjacent first color conversion layers 310 and second color conversion layers 320, two adjacent first pixel electrodes 410 and second pixel electrodes 420, and a reference electrode 500. The display panel 900 of the present invention may comprise an opposite substrate 190, a pixel structure 800, and a non-self-emissive display medium 910. The pixel structure 800 is disposed corresponding to the opposite substrate 190. The non-self-luminous display medium 910 is disposed between the substrate 100 and the opposite substrate 190. Non-self emissive display medium 910 comprises liquid crystal or other suitable non-self emissive display material. The reference electrode 500 is separated from two adjacent first pixel electrodes 410 and second pixel electrodes 420, and the two adjacent first pixel electrodes 410 and second pixel electrodes 420 are also separated from each other. In other embodiments, the display panel 900 may further include a counter electrode 920 disposed on the counter substrate 190.
Two adjacent first data lines 210 and second data lines 220 are disposed on the substrate 100 for transmitting data signals to corresponding thin film transistors (not shown). The first data line 210 and the second data line 220 are separated from each other by a gap 290, and the thin film transistor may be a bottom gate transistor, a top gate transistor, or other suitable transistors.
Two adjacent first color conversion layers 310 and second color conversion layers 320 are disposed on two adjacent data lines 210 and 220, the first color conversion layers 310 correspond to the first data lines 210, and the second color conversion layers 320 correspond to the second data lines 220. The first color conversion layer 310 is at least partially overlapped with the first data line 210, the second color conversion layer 320 extends over the second data line 220 and is partially overlapped with the first data line 210, and the vertical projections of the first color conversion layer 310 and the second color conversion layer 320 are partially overlapped on a portion of the first data line 210 to form an overlapped area 610. Where, for example, the embodiment shown in fig. 1, the overlap region 610 has a left side boundary 610a and a right side boundary 610 b.
For example, in the embodiment shown in fig. 1, viewed from different angles, the first color conversion layer 310 extends from the left outer side of the first data line 210 to the right to overlap and cover a portion of the upper surface of the first data line 210, the second color conversion layer 320 extends from the right outer side of the second data line 220 to the left, completely covers the surface of the second data line 220, then, the data line is extended leftwards to overlap a part of the surface of the first data line 210, and further overlapped on the first color conversion layer 310 covering the first data line 210, the overlapping area 610 is the area where the first color conversion layer 310 and the second color conversion layer 320 overlap on a portion of the first data line 210, the vertical projection of the right edge of the first color conversion layer 310 on the first data line 210 corresponds to the right boundary 610b, and the vertical projection of the left edge of the second color conversion layer 320 on the first data line 210 corresponds to the left boundary 610 a. In other words, the interface of the first color conversion layer 310 and the second color conversion layer 320 falls over the first data line 210. Light (e.g., light from a backlight module or other suitable sources) can be converted into first and second colors by the first and second color conversion layers 310 and 320, respectively, and the colors of the first and second colors can be substantially different.
Two adjacent first pixel electrodes 410 and second pixel electrodes 420 are disposed on two adjacent first color conversion layers 310 and second color conversion layers 320. For example, in this embodiment, the first pixel electrode 410 and the second pixel electrode 420 are deposited or otherwise disposed on the surfaces of the first color conversion layer 310 and the second color conversion layer 320, respectively. The first pixel electrode 410 corresponds to the first color conversion layer 310, the second pixel electrode 420 corresponds to the second color conversion layer 320, the first pixel electrode 410 partially overlaps the first data line 210, and the second pixel electrode 420 partially overlaps the second data line 220. For example, the first pixel electrode 410 overlaps a vertical projection portion of the first data line 210 on the substrate 100, and the second pixel electrode 420 overlaps a vertical projection portion of the second data line 220 on the substrate 100.
The reference electrode 500 is disposed on the two adjacent color conversion layers 310 and 320 and between the two adjacent pixel electrodes 410 and 420, wherein the reference electrode 500 covers the gap 290, a portion of the first data line 210 and a portion of the second data line 220. In some embodiments, one end of the reference electrode 500 overlaps the partial overlap region 610. For example, the reference electrode 500, the gap 290, a portion of the first data line 210 and a portion of the second data line 220 overlap with each other in a vertical projection on the substrate 100, and one end of the reference electrode 500 overlaps with the vertical projection of the partially overlapped region 610 on the substrate 100. The reference electrode 500 may be a common electrode or an adjustable potential electrode for providing a reference potential. Preferably, the reference electrode 500 is used to control the non-self-luminous display medium 910 (e.g., liquid crystal) between two adjacent first data lines 210 and second data lines 220 to be in a dark state (e.g., dark state), so as to prevent light leakage. Fig. 2 is a schematic top view of the first data line 210, the second data line 220, the first pixel electrode 410, the second pixel electrode 420, and the reference electrode 500 in the embodiment of fig. 1. At least one of the first pixel electrode 410 and the second pixel electrode 420 may optionally further include a plurality of slits 401. The reference electrode 500 may optionally not include the slit 401, but is not limited thereto.
In the pixel structure 800 of the invention, since the vertical projections of the first color conversion layer 310 and the second color conversion layer 320 on the first data line 210 partially overlap to form the overlap region 610, that is, the vertical projection of the overlap region 610 on the substrate 100 is within the range of the vertical projection of the first data line 210 on the substrate 100, the first data line 210 can be used to block the light leakage possibly generated in the overlap region 610 of the first color conversion layer 310 and the second color conversion layer 320. Accordingly, the embodiment of the present invention can avoid the decrease of the aperture ratio of the sub-pixel (or called as pixel structure) caused by using extra widened shielding metal as the main shielding light leakage design. On the other hand, in one embodiment, the width of the first data line 210 is preferably greater than the width of the second data line 220, so as to ensure that the perpendicular projection of the overlap region 610 on the substrate 100 is within the range of the perpendicular projection of the first data line 210 on the substrate 100.
In the embodiment shown in fig. 1, the first data line 210 and the second data line 220 may be located at the same layer (or called the same patterned layer), i.e. at the same level, with a spacing W therebetween1But is not limited thereto. In the different embodiment shown in fig. 3, the first data line 210 and the second data line 220 are respectively a patterned layer 219 and a patterned layer 229 disposed above and below, and the vertical projection distance of the two on the substrate 100 is W2。W1Greater than W2，W2May be about 0, i.e. the vertical projections of the two on the substrate 100 may be aligned with each other, and the rest of similar or same elements and reference numerals may refer to the foregoing embodiments, which are not repeated herein. With this arrangement, the first data line 210 and the second data line 220 can be as close as possible under the condition that the vertical projections of the first data line 210 and the second data line 220 on the substrate 100 do not overlap with each other, and the first data line 210 and the second data line 220 can still be prevented from contacting each other. Furthermore, the aperture ratio of the sub-pixel (or called pixel structure) can be slightly higher than that of the foregoing embodiment.
For example, in the different embodiment shown in fig. 4, the pixel structure 800 of the present invention may optionally further include a shielding electrode 700 disposed on the substrate 100 and under the two adjacent first data lines 210 and second data lines 220, and other similar or identical elements and reference numerals may refer to the foregoing embodiments, which are not repeated herein. In the vertical projection direction of the substrate 100, the shielding electrode 700 overlaps at least a portion of the gap 290. For example, one end of the shielding electrode 700 may overlap only a portion of the first data line 210, and the other end of the shielding electrode 700 may not overlap the second data line 220. In some embodiments, the shielding electrode 700 may overlap a portion of the first data line 210, the overlapping region 610, and a portion of the second data line 220. In still another embodiment, the shielding electrode 700 may overlap a portion of the first data line 210 and overlap a portion of the overlapping region 610. The shielding electrode 700 may be a floating electrode, and the material of the shielding electrode may be different from the material of the first data line 210 and the second data line 220. Furthermore, the widths of the two adjacent first data lines 210 and the second data lines 220 may be optionally substantially the same, but are not limited thereto, and in some embodiments, the widths of the two adjacent first data lines 210 and the second data lines 220 may be different. In the present embodiment, in order to increase the aperture ratio of the sub-pixel (or referred to as a pixel structure), the width of the first data line 210 is reduced to reduce the shielding range, so that the projection of the overlap region 610 on the substrate 100 may not be entirely within the projection range of the first data line 210 on the substrate 100. Therefore, the shielding electrode 700 is used to assist the first data line 210 in shielding light leakage from the overlapping region 610 of the first color conversion layer 310 and the second color conversion layer 320. Although the shielding electrode 700 is disposed in this embodiment, since the light leakage of the overlapping region 610 is still mainly shielded by the first data line 210, the width of the shielding electrode 700 does not need to be increased, and thus the aperture ratio of the sub-pixel (or called as pixel structure) is not decreased. Moreover, the aperture ratio of the sub-pixel (or called as pixel structure) designed in this embodiment can still be increased compared to the aperture ratio of the sub-pixel (or called as pixel structure) designed to mainly block light leakage by additionally using the widened shielding metal (for example, the width of the additionally used widened shielding metal is much larger than the width of the shielding electrode 700 of this embodiment).
As shown in fig. 5, in a different embodiment, the first data line 210 has at least a first segment 211 and a second segment 212, the second data line 220 has at least a third segment 223 and a fourth segment 224, a width of the first segment 211 of the first data line 210 corresponding to the overlapping region 610 (see fig. 1) is greater than a width of the second segment 212 of the first data line 210 and a width of the third segment 223 and a fourth segment 224 of the second data line 220, and other similar or identical elements and reference numerals may refer to the foregoing embodiment and are not repeated herein, and the foregoing embodiment may also be used in the present embodiment (for example, fig. 1, fig. 3, and fig. 4). The film layer of the first segment 211 corresponding to the overlapping region 610 may be different from one of the film layer of the second segment 212 and the film layers of the third segment 223 and the fourth segment 224. The width of the first data line 210 in the overlapping region 610 can be widened, so as to enhance the effect of shielding light leakage. The first section 211 and the second section 212, the third section 223 and the fourth section 224 may be located at different layers to avoid contact. In addition, the width of the fourth segment 224 may be further greater than the width of the third segment 223, for example, the width of the first segment 211 of the first data line 210 and the width of the fourth segment 224 of the second data line 220 are greater than the width of the second segment 212 of the first data line 210 and the width of the third segment 223 of the second data line 220, which may achieve the effect of tight arrangement of sub-pixels (or referred to as pixel structures), and may also help the uniformity of the overall brightness of the display panel.
Furthermore, the insulating layer 110 and/or the insulating layer 120 in the foregoing embodiments are used to separate different layers, such as: the first data line 210 and the second data line 220 shown in fig. 3, the first data line 210 and the second data line 220 shown in fig. 4, and so on, and at least one of the insulating layer 110 and the insulating layer 120 may be a single-layer or multi-layer structure, and the material thereof may be an inorganic material, an organic material, or other suitable materials.
