Fig. 1 is a schematic top view of a display panel according to an embodiment of the invention; fig. 2 is a schematic cross-sectional view of a peripheral area of the display panel shown in fig. 1, and as shown in the figure, the display panel 10 includes an array substrate 11 and a color filter substrate 12 that are oppositely disposed, and a display layer 30 is disposed between the array substrate 11 and the color filter substrate 12, where the display panel 10 may be a liquid crystal display panel, and then the display layer 30 is a liquid crystal layer, and the display panel 10 may also be an organic light emitting display panel, and then the display layer 30 is an organic light emitting material. The display panel 10 includes a display region 13 (shown as an area within a white dotted line in fig. 1) and a peripheral region 14 surrounding the display region 13, and the array substrate 11 and the color filter substrate 12 are disposed in the peripheral region 14. In the display region 13, a plurality of pixel units 15 are arranged at intervals on a side of the array substrate 11 facing the color filter substrate 12. On the side of the color filter substrate 12 facing the array substrate 11, a plurality of color filter units 16 are provided corresponding to the plurality of pixel units 15, and a second black matrix layer 17 is provided corresponding to an interval region between the plurality of pixel units 15.
In the peripheral region 14, the color filter substrate 12 and the array substrate 11 are bonded and connected by the sealant 31, a first black matrix layer 18 is disposed on a side of the color filter substrate 12 facing the array substrate 11, a plurality of annular openings are disposed in the first black matrix layer 18, and fig. 1 and 2 show three annular openings, which are a first annular opening 181, a second annular opening 182, and a third annular opening 183, respectively. The polarizer 19 is disposed on a side of the color filter substrate 12 away from the array substrate 11, the polarizer 19 covers a part of the peripheral region 14 of the display region 13, and the polarizer 19 and the plurality of annular openings are overlapped.
Among the plurality of annular openings disposed in the first black matrix layer 18, the first annular opening 181 is located near the edge of the peripheral region 14 and farthest from the display region 13, the third annular opening 183 is located adjacent to the display region 13, and the second annular opening 182 is located between the first annular opening 181 and the third annular opening 183. A plurality of annular openings are provided in the first black matrix layer 18 in the peripheral region 14, and a path of static electricity from the black matrix layer in the peripheral region of the color film substrate into the display panel can be cut. Since the black matrix layer has a slight conductivity, static electricity can be conducted from the peripheral region to the display region along the black matrix of the continuous structure, easily causing damage to devices such as thin film switching transistors, electrodes, or wirings of the display region, and thus forming display defects. In the embodiment of the present invention, the plurality of annular openings are formed in the first black matrix layer 18 in the peripheral region 14, so that the path for static electricity to enter the display panel from the black matrix layer in the peripheral region of the color film substrate is cut off, and the yield and reliability of the display panel are improved.
In the first embodiment, the width of the annular opening on the side away from the display region 13 is set larger than the width of the annular opening on the side close to the display region 13. Specifically, in the structure shown in fig. 1 and 2, the width d1 of the first annular opening 181 is set to be larger than the width d3 of the third annular opening 183. The plurality of annular openings provided in the first black matrix layer 18 in the peripheral region 14 can improve the performance of the display panel against static electricity, but also increase the probability of light leakage in the peripheral region. Because the black matrix layer mainly has the function of shading, when the hollowed annular opening is arranged in the black matrix, the opening is transparent, and the wiring reflection light on the array substrate is easy to be observed from the transparent annular opening, namely the edge light leakage is poor. In the embodiment of the present invention, the width of the annular opening on the side far from the display region 13 is set larger than the width of the annular opening on the side near the display region 13, so that the light leakage defect can be reduced while suppressing electrostatic introduction. Specifically, the width of the ring-shaped opening on the side far from the display region 13 is set larger than the width of the ring-shaped opening on the side near the display region 13, and taking the structure in fig. 1 and 2 as an example, the width d1 of the first ring-shaped opening 181 is larger than the width d3 of the third ring-shaped opening 183, because the width d1 of the first ring-shaped opening 181 is larger, the ability to block static electricity is stronger, but because the light leakage is not serious because the edge of the peripheral region 14 is near. The width d3 of the third annular opening 183 is small, although the electrostatic blocking capability is relatively weak, since most of the static electricity is blocked by the first annular opening 181, the third annular opening 183 with a small width only needs to block a small part of the static electricity, and the requirement of electrostatic blocking can also be met; moreover, since the width d3 of the third annular opening 183 is small, after the polarizer 19 is attached to the side of the color filter substrate 12 away from the array substrate 11, light leakage can be blocked, and the light leakage phenomenon can be eliminated from the viewing angle.
In the display panel provided by the first embodiment of the invention, the plurality of annular openings are arranged in the first black matrix layer on the side of the color film substrate facing the array substrate, and the width of the annular opening on the side far away from the display area is larger than that of the annular opening on the side close to the display area, so that static electricity can be blocked, the light leakage phenomenon can be eliminated, and the comprehensive yield of the display panel is improved.
Alternatively, the second annular opening 182, which is disposed between the first annular opening 181 and the third annular opening 183 and has a width d2 equal to the width d1 of the first annular opening 181, improves the antistatic performance of the display panel; the width d3 of the third annular opening 183 can be equal to, so that light leakage is reduced; the width d2 of the second annular opening 182 can be set to be smaller than the width d1 of the first annular opening 181 and larger than the width d3 of the third annular opening 183, a structure that the widths of the plurality of annular openings gradually decrease from the side far away from the display area 13 to the side close to the display area 13 is formed, the plurality of annular openings with gradually decreasing widths can improve the static suppression capability in the direction close to the edge of the display panel, reduce or eliminate light leakage in the direction close to the display area, and improve the comprehensive yield of the display panel. Further alternatively, the width of the plurality of annular openings may range between 5 μm and 25 μm.
Optionally, the second black matrix layer and the first black matrix layer are disposed in the same layer and formed in the same process step, and when the second black matrix layer is etched, a plurality of annular openings in the first black matrix layer are also etched and formed at the same time, so that a separate process step is not required to form the first black matrix layer and the plurality of annular openings therein.
In addition, in the first embodiment, the plurality of annular openings are exemplified by three annular openings, but the present invention is not limited thereto, and the number of the plurality of annular openings may be other than three.
Referring to fig. 3, fig. 3 is a schematic view of a display panel according to a second embodiment of the present invention, which is different from the first embodiment in that the width of the annular opening near the edge of the color film substrate 12 is greater than the widths of the remaining annular openings, and the widths of the remaining annular openings are equal. Specifically, as shown in the figure, of the plurality of annular openings in the first black matrix layer 18, the first annular opening 184 is an annular opening close to the edge of the color filter substrate 12, and the width d4 of the first annular opening 184 is greater than the width d5 of the second annular opening 185 and the width d6 of the third annular opening 186. Optionally, the width of the annular opening close to the edge of the color filter substrate is 25 μm, and the widths of the remaining annular openings are 5 μm. The width of the annular opening close to the edge of the color film substrate is set to be larger than the widths of the rest annular openings, so that most of static electricity can be blocked by the annular opening close to the edge of the color film substrate, and the widths of the rest annular openings are set to be narrower, so that poor light leakage can be reduced. Similarly, in the second embodiment, the plurality of annular openings are exemplified by three annular openings, but the present invention is not limited thereto, and the number of the plurality of annular openings may be other than three.
Referring to fig. 4, fig. 4 is a schematic view of a display panel according to a third embodiment of the present invention, in the structure shown in fig. 4, an insulating cover layer 20 is further disposed on a side of the first black matrix layer 18 facing the array substrate 11, and the insulating cover layer 20 covers the first black matrix layer 18 and is filled in the plurality of annular openings in the first black matrix layer 18. Specifically, a first annular opening 187, a second annular opening 188, and a third annular opening 189 are provided in the first black matrix layer 18, and the insulating cover layer 20 covered on the first black matrix layer 18 is further filled into the first annular opening 187, the second annular opening 188, and the third annular opening 189. Further, a first light shielding layer 21 is further provided on the side of the insulating cover layer 20 facing the array substrate 11, and the first light shielding layer 21 and the plurality of annular openings are provided to overlap. In the third embodiment, the insulating cover layer 20 and the first light shielding layer 21 are added to completely eliminate the edge light leakage defect. First, a plurality of ring-shaped openings are formed in the first black matrix layer 18 to cut off a path of external static electricity from the first black matrix layer 18 into the display panel, then the insulating cover layer 20 is formed on the first black matrix layer 18 and the insulating cover layer 20 is also filled in the plurality of ring-shaped openings, and then the first light-shielding layer 21 overlapping the plurality of ring-shaped openings is formed on the insulating cover layer 20 to shield light transmitted through the plurality of ring-shaped openings, thereby eliminating a light leakage phenomenon. Alternatively, the material of the first light shielding layer 21 and the material of the first black matrix layer 18 are the same.
Alternatively, as shown in fig. 4, the first light-shielding layers 21 may overlap the respective annular openings, and the first light-shielding layers 21 overlapping the respective annular openings may not be connected to each other. Alternatively, as shown in fig. 5, in the second display panel provided in the third embodiment, the first light shielding layer 21 has a large width and overlaps with each of the annular openings.
Referring to fig. 6, which is a schematic diagram of a third display panel according to a third embodiment of the present invention, in the structure shown in fig. 6, a first light-shielding layer 21 is disposed between the color film substrate 12 and the first black matrix layer 18, and the first light-shielding layer 21 is overlapped with the plurality of annular openings. Specifically, a first annular opening 187, a second annular opening 188 and a third annular opening 189 are provided in the first black matrix layer 18, the first light-shielding layer 21 provided between the color filter substrate 12 and the first black matrix layer 18 is in a plurality of annular shapes and is respectively overlapped with the first annular opening 187, the second annular opening 188 and the third annular opening 189, and the width of the annular first light-shielding layer 21 is the same as or slightly larger than that of the corresponding annular opening, so that the plurality of annular openings are shielded, and light leakage of the annular openings is avoided.
Alternatively, the first light shielding layer 21 may be an insulating material, and the first light shielding layer 21 and the first black matrix layer 18 may be disposed in direct contact. Alternatively, the first light shielding layer 21 may be made of a conductive material or a weakly conductive material in conformity with the material of the first black matrix layer 18, and an insulating cover layer 20 is provided between the first light shielding layer 21 and the first black matrix layer 18. Specifically, the insulating cover layer 20 is disposed after the first light shielding layer 21 is formed, the insulating cover layer 20 fills the gap between the first light shielding layer 21 to form a flat surface, and is subsequently formed on the flat insulating cover layer 20 without affecting the structure of the first black matrix layer 18. The insulating cover layer 20 electrically isolates the first light-shielding layer 21 from the first black matrix layer 18, so that static electricity does not have a path into the inside of the display panel.
Alternatively, as shown in fig. 6, the first light shielding layers 21 may overlap the respective annular openings, and the first light shielding layers 21 overlapping the respective annular openings may not be connected to each other. Alternatively, as shown in fig. 7, in the fourth display panel provided in the third embodiment, the first light-shielding layer 21 has a large width and overlaps with each of the annular openings to shield the plurality of annular openings. In the fourth display panel provided in the third embodiment, if the first light-shielding layer 21 is formed using an insulating material, the insulating cover layer 20 may not be provided, and the first light-shielding layer 21 may be formed directly on the first light-shielding layer 21. If the first light shielding layer 21 is formed using a conductive or weakly conductive material, an insulating cover layer 20 may be disposed between the first light shielding layer 21 and the first black matrix layer 18 such that the first light shielding layer 21 and the first black matrix layer 18 are electrically isolated.
