Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, and more particularly to a display panel and a display device. Background Technology
[0002] In the 21st century, with the development of information technology, liquid crystal displays (LCDs) have stood out in the flat panel display field. The display devices we use every day, such as mobile phones, computers, televisions, and watches, all widely use thin-film transistor liquid crystal displays. With its advantages such as low radiation, low power consumption, and low space occupancy, thin-film transistor liquid crystal displays have been widely used in various industries.
[0003] However, when COA (Color Filter on Array) type LCD panels are subjected to external force, a whitening phenomenon (Moving Mura) will appear in dark scenes. Microscopic observation shows light leakage near the data lines (the edges of the black matrix and the gaps between the common lines and the data lines) and the scan lines (the edges of the black matrix and the gaps between the common lines and the scan lines). This problem is very likely to occur in medium and large-sized display panels. Therefore, it is urgent to solve the problem of this whitening phenomenon in dark scenes. Utility Model Content
[0004] The purpose of this application is to provide a display panel and display device. By placing a color resist layer on the color filter substrate, the edge of the black matrix layer on the color filter substrate is relatively flat, and the liquid crystal near the black matrix layer and the color resist layer can be quickly reset, which can improve the situation of the dark screen turning white after the display panel is tapped to a certain extent.
[0005] This application discloses a display panel including a color filter substrate and an array substrate disposed opposite each other. A liquid crystal layer is disposed between the color filter substrate and the array substrate. The array substrate includes a first substrate, a first metal layer, a second metal layer, an insulating layer, and a first electrode layer. The first metal layer and the insulating layer are both disposed on the first substrate. The second metal layer is located on the side of the insulating layer away from the first substrate. The first metal layer is located on both sides of the second metal layer. The first electrode layer is disposed on the side of the first metal layer away from the first substrate. The color filter substrate includes a second substrate, a black matrix layer, a color resist layer, and a second electrode layer. The black matrix layer and the color resist layer are disposed on the second substrate. The second electrode layer is disposed on the second substrate and covers the black matrix layer and the color resist layer. The projection of the end of the black matrix layer away from the color resist layer in the thickness direction of the display panel partially coincides with the first metal layer.
[0006] Optionally, the display panel also includes multiple common lines, which are arranged in a crisscross pattern and are parallel to the first metal layer and the second metal layer, respectively.
[0007] The black matrix layer has a normal working state and a misaligned working state. When the black matrix layer is in the normal working state or the misaligned working state, the projection of the black matrix layer in the thickness direction of the display panel covers the gap between the first metal layer and the common line and the gap between the second metal layer and the common line.
[0008] Optionally, the width of the black matrix layer is greater than or equal to 8 micrometers.
[0009] Optionally, the projection of the black matrix layer onto the thickness direction of the display panel covers a portion of the common line, and the width of the common line is greater than the gap between the common line and the first metal layer, and also greater than the gap between the common line and the second metal layer.
[0010] Optionally, the display panel further includes a planarization layer disposed on the side of the black matrix layer away from the second substrate, and the second electrode layer covers the planarization layer.
[0011] Optionally, the display panel further includes a support pillar disposed between the array substrate and the color filter substrate;
[0012] One end of the support column abuts against the array substrate, and the other end is spaced apart from the color filter substrate.
[0013] Optionally, the liquid crystal in the liquid crystal layer is a fast-response liquid crystal.
[0014] Optionally, the display panel further includes a polarizer disposed on the side of the color filter substrate away from the array substrate;
[0015] The polarizer is a wide-viewing-angle polarizer.
[0016] This application also discloses a display panel, including a color filter substrate and an array substrate disposed opposite each other, with a liquid crystal layer disposed between the color filter substrate and the array substrate. The array substrate includes a first substrate, a first metal layer, a second metal layer, a color resist layer, a first electrode layer, and a black matrix layer. The first metal layer and the second metal layer are both disposed on the first substrate, and the first metal layer is located on both sides of the second metal layer. The color resist layer is disposed on the first substrate and covers the first metal layer and the second metal layer. The first electrode layer is disposed on the side of the color resist layer away from the first substrate. The black matrix layer is disposed on the color resist layer. The projections of the two ends of the black matrix layer in the thickness direction of the display panel partially coincide with the first metal layer. An insulating layer is disposed between the first metal layer and the second metal layer.
[0017] This application also discloses a display device, which includes a driving circuit and a display panel as described in any of the above claims, wherein the driving circuit drives the display panel to be configured.
[0018] The display panel of this application has a color resist layer disposed on the color filter substrate. The placement of the color resist layer makes the edge of the black matrix layer on the color filter substrate relatively flat. Compared with the original solution of only placing the black matrix layer on the color filter substrate, the edge of the black matrix layer is close to the color resist layer, making the second electrode layer covering the black matrix layer relatively flat. The second electrode layer does not have a stepped structure, which is beneficial to the alignment and adhesion of the liquid crystal layer near the color filter substrate. When the display panel is hit by an external force and the color filter substrate is displaced, the liquid crystal near the black matrix layer and the color resist layer can quickly reset due to the placement of the black matrix layer and the color resist layer. The alignment and adhesion of the liquid crystal will not be greatly affected, which can improve the situation of the dark screen appearing white after the display panel is hit to a certain extent.

[0032] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0033] like Figure 1 As shown in the first embodiment of this application, a display panel is disclosed. The display panel includes a color filter substrate and an array substrate disposed opposite each other. A liquid crystal layer is disposed between the color filter substrate and the array substrate. The array substrate includes a first substrate 501, a first metal layer 502, a second metal layer 503, an insulating layer 512, and a first electrode layer 504. The first metal layer 502 and the second metal layer 503 are both disposed on the first substrate 501. The insulating layer 512 is also disposed on the first substrate 501. The second metal layer 503 is located on the side of the insulating layer 512 away from the first substrate 501, that is, the first metal layer 502 and the second metal layer 503 are spaced apart, and a space is provided between the first metal layer 502 and the second metal layer 503. An insulating layer 512 is provided, and the first metal layer 502 is located on both sides of the second metal layer 503. The first electrode layer 504 is disposed on the side of the first metal layer 502 away from the first substrate 501. The color filter substrate includes a second substrate 505, a black matrix layer 506, a color resist layer 507, and a second electrode layer 508. The black matrix layer 506 and the color resist layer 507 are disposed on the second substrate 505. The second electrode layer 508 is disposed on the second substrate 505 and covers the black matrix layer 506 and the color resist layer 507. The projection of the end of the black matrix layer 506 away from the color resist layer 507 in the thickness direction of the display panel partially coincides with the first metal layer 502. In this embodiment, the thickness direction of the display panel is as follows: Figure 1 As shown on the X-axis, that is, in the direction of the X-axis, the projection of the end of the black matrix layer 506 away from the color resist layer 507 partially coincides with the first metal layer 502, wherein the first metal layer 502 is a data line and the second metal layer 503 is a scan line.
[0034] In this embodiment, by disposing the color resist layer 507 on the color filter substrate, and disposing the color resist layer 507 and the black matrix layer 506 together on the second substrate 505 of the color filter substrate, the placement of the color resist layer 507 makes the edges of the black matrix layer 506 on the color filter substrate relatively flat, thus making the second electrode layer 508 covering the black matrix layer 506 relatively flat. Compared to the original solution of only disposing the black matrix layer 506 on the color filter substrate, the edges of the black matrix layer 506 are close to the color resist layer 507, making the second electrode layer 508 covering the black matrix layer 506 relatively flat. The second electrode layer 508 does not have a stepped structure, which is beneficial for the liquid crystal alignment and adhesion of the liquid crystal layer near the color filter substrate. When the display panel of this embodiment is subjected to an external force that causes the color filter substrate to shift, the liquid crystal near the black matrix layer 506 and the color resist layer 507 can quickly reset due to the provision of the black matrix layer 506 and the color resist layer 507. The alignment and adhesion of the liquid crystal are not significantly affected, which can improve the whitening of dark images after the display panel is hit to a certain extent. At the same time, the end of the black matrix layer 506 away from the color resist layer 507 overlaps with the data line. The gap between the data line and the scan line is blocked by the black matrix layer 506 and the color resist layer 507, and there is no light leakage from the gap. This makes the display panel have no difference in brightness on a macroscopic scale, and the whitening phenomenon caused by the display panel being hit by an external force is improved.
[0035] Furthermore, such as Figure 2As shown, the display panel also includes multiple common lines 509. These common lines 509 are arranged in a crisscross pattern and are parallel to the first metal layer 502 and the second metal layer 503, respectively. That is, the common lines 509 are parallel to the data lines and scan lines, respectively. The black matrix layer 506 has a normal working state and a misaligned working state. The misaligned working state refers to the state where the black matrix layer 506 shifts after the display panel is struck by an external force. In both the normal working state and the misaligned working state, the projection of the black matrix layer 506 onto the thickness direction of the display panel covers the gap between the first metal layer 502 and the common lines 509, as well as the gap between the second metal layer 503 and the common lines 509. In other words, the black matrix layer 506 blocks the gap between the data lines and the common lines 509, and the gap between the scan lines and the common lines 509, so that the gap between the data lines and the common lines 509 is... The gap between the scan line and the common line 509 will not leak light, reducing light leakage points in the display panel. By widening the width of the black matrix layer 506, the black matrix layer 506 can still block the gap between the data line and the common line 509 and the gap between the scan line and the common line 509 even after being displaced by external force, thus preventing light leakage from the display panel after being hit by external force. In this embodiment, the width of the black matrix layer 506 is greater than or equal to 8 micrometers. The total width of the black matrix layer 506 consists of the original width and the widened width. The original width is the width of the black matrix layer 506 before widening, which varies depending on the design of the display panel. The widened width is greater than or equal to 8 micrometers, that is, the widened width of the black matrix layer 506 is at least 8 micrometers. Therefore, the total width of the black matrix layer 506 in this embodiment is greater than or equal to 8 micrometers.
[0036] Besides the aforementioned solution of widening the black matrix layer 506 to ensure it can still block the gaps between the data lines and common lines 509 and the scan lines and common lines 509 after the display panel is displaced by external force, thus preventing light leakage, the light leakage phenomenon can also be improved by changing the line width of the common lines 509; specifically, such as... Figure 3 As shown, the projection of the black matrix layer 506 on the thickness direction of the display panel covers part of the common line 509. The width of the common line 509 is greater than the gap between the common line 509 and the first metal layer 502, and also greater than the gap between the common line 509 and the second metal layer 503.
[0037] In this embodiment, the display panel widens the width of the common line 509. While the positions of the common line 509 and the scan lines remain unchanged, the gap between the common line 509 and the scan lines is reduced. Similarly, while the positions of the common line 509 and the data lines remain unchanged, the gap between the common line 509 and the scan lines, as well as the gap between the common line 509 and the data lines, is reduced. This ensures that the black matrix layer 506 can still effectively block the gaps between the data lines and the common line 509, and between the scan lines and the common line 509, thus preventing light leakage after the display panel is struck. Compared to the solution described above that simply widens the black matrix layer 506, this avoids the reduction in aperture ratio and transmittance of the display panel that would result from widening the black matrix layer 506.
[0038] Furthermore, the light leakage phenomenon caused by impacts on the display panel can be improved by using other types of liquid crystals. Fast-response liquid crystals can be used, as they have lower rotational viscosity and elastic constants, resulting in faster response times. After the display panel is impacted, the liquid crystal can quickly return to its pre-impact state, thus improving the light leakage phenomenon. Simultaneously, the display panel also includes a polarizer disposed on the side of the color filter substrate away from the array substrate. This polarizer is a wide-viewing-angle polarizer, which disperses the light emitted perpendicularly from the display panel to increase side-viewing light, thereby improving the viewing angle. Light leakage in the dark is diffused by the wide-viewing-angle polarizer, preventing it from being directly observed and thus improving the light leakage phenomenon after impacts on the display panel in the dark.
[0039] Furthermore, from Figure 3 and Figure 4 As can be seen, the black matrix layer 506 on the data line side and the black matrix layer 506 on the scan line side are usually designed with a break to improve the adhesion of liquid crystal at the edge of the black matrix layer 506. In this embodiment, the black matrix layer 506 on the data line side and the black matrix layer 506 on the scan line side can also be merged, i.e., a sealing design, to reduce light leakage points at the edge of the black matrix layer 506. In addition, a low-viscosity PI (polyimide) material or a thickened PI (polyimide) film can be used to allow more PI to adhere to the edge of the black matrix layer 506, which is beneficial for liquid crystal alignment and can improve the dark-state whitening caused by light leakage at the edge of the black matrix layer 506.
[0040] In the above-described solution, although increasing the width of the black matrix layer 506 can improve the light leakage phenomenon after the display panel is hit by external force to a certain extent, widening the black matrix layer 506 will lead to a decrease in the aperture ratio of the display panel, affecting the display effect. Therefore, the inventors of this application have made certain improvements to the above-described solution, such as... Figure 4 As shown, as a second embodiment of this application, which is an improvement of the first embodiment of this application, a display panel is disclosed. The display panel further includes a planarization layer 510. The planarization layer 510 is disposed on the side of the black matrix layer 506 away from the second substrate 505. The planarization layer 510 covers the black matrix layer 506. The second electrode layer 508 covers the planarization layer 510.
[0041] In this embodiment, by setting a planarization layer 510 on the display panel, the edge of the black matrix layer 506 is made relatively smooth, thereby increasing the anchoring force of the liquid crystal near the edge of the black matrix layer 506, optimizing the liquid crystal alignment, and enabling the liquid crystal to quickly recover to the state before the impact after the display panel is hit by an external force, thus improving the phenomenon of light leakage when the display panel is hit. It should be noted that in this embodiment, the color resist layer 507 can be set on the color filter substrate as described in the first embodiment, or it can be set on the array substrate. There is no limitation here, and the designer can choose to design according to actual needs.
[0042] In a display panel, when the spacing between the array substrate and the color filter substrate is the same, the higher the support pillar 511, the greater the compressive force exerted by the color filter substrate and the array substrate on the support pillar 511. This results in greater friction between the support pillar 511 and the color filter substrate. Consequently, when the display panel is struck by an external force and the color filter substrate shifts, the color filter substrate 200 is more difficult to return to its initial position due to the friction between the support pillar 511 and the color filter substrate. Therefore, the inventors of this application have further improved the design of the display panel 100, such as... Figure 5 As shown, as a third embodiment of this application, which is an improvement of the first embodiment of this application, a display panel 100 is disclosed. The display panel 100 further includes a support post 511. The support post 511 is disposed between the array substrate 300 and the color filter substrate 200. One end of the support post 511 abuts against the array substrate 300, and the other end is spaced apart from the color filter substrate 200.
[0043] In this embodiment, the height of the support column 511 is reduced so that one end of the support column 511 abuts against the array substrate 300, and the other end is spaced apart from the color filter substrate 200. The gap between the support column 511 and the color filter substrate 200 is filled with liquid crystal. In this way, when the display panel 100 is hit by an external force, the friction between the color filter substrate 200 and the array substrate 300 is greatly reduced because the space between them is filled with liquid crystal, thus reducing the difficulty for the color filter substrate 200 to return to its initial position. In this embodiment, the height of the support column 511 can be 2.125 micrometers.
[0044] like Figure 6 As shown, in the fourth embodiment of this application, a display panel 100 is disclosed. The display panel 100 includes a color filter substrate 200 and an array substrate 300 disposed opposite each other. A liquid crystal layer 400 is disposed between the color filter substrate 200 and the array substrate 300. The array substrate 300 includes a first substrate 501, a first metal layer 502, a second metal layer 503, a color resist layer 507, a first electrode layer 504, and a black matrix layer 506. The first metal layer 502 and the second metal layer 503 are both disposed on the first substrate 501, and the first metal layer 502 is disposed on the first substrate 501. Metal layer 502 is located on both sides of the second metal layer 503. Color resist layer 507 is disposed on the first substrate 501 and covers the first metal layer 502 and the second metal layer 503. First electrode layer 504 is disposed on the side of color resist layer 507 away from the first substrate 501. Black matrix layer 506 is disposed on color resist layer 507. The projections of both ends of black matrix layer 506 in the thickness direction of display panel 100 partially coincide with the first metal layer 502. In this embodiment, the thickness direction of display panel 100 is as follows: Figure 6 As shown on the X-axis, that is, in the direction of the X-axis, the projections of the two ends of the black matrix layer 506 partially coincide with the first metal layer 502, the first metal layer 502 is a data line, and the second metal layer 503 is a scan line;
[0045] In the display panel 100 of this embodiment, by setting the black matrix layer 506 on the array substrate 300, and the projection of both ends of the black matrix layer 506 in the thickness direction of the display panel 100 partially coincides with the first metal layer 502, the black matrix layer 506 can block the gap between the data line and the common line 509 and the gap between the scan line and the common line 509. This ensures that even if the glass substrate on the color filter substrate 200 side of the display panel 100 shifts when the display panel 100 is hit by an external force, the black matrix layer 506 can still effectively block the gap between the data line and the common line 509 and the gap between the scan line and the common line 509, preventing light leakage from the gap between the data line and the common line 509 and the gap between the scan line and the common line 509. This improves the uneven brightness phenomenon of the display panel 100 after being hit by an external force, thereby improving the whitening phenomenon of the display panel 100.
[0046] Furthermore, the light leakage phenomenon of the display panel 100 due to impact can be improved by using other types of liquid crystals. For example, a fast-response liquid crystal can be used. Fast-response liquid crystals have lower rotational viscosity and elastic constant parameters, resulting in a faster response speed. After the display panel 100 is impacted, the liquid crystal can quickly return to its state before the impact, thus improving the light leakage phenomenon. The display panel 100 also includes a polarizer, which is disposed on the side of the color filter substrate 200 away from the array substrate 300. The polarizer is a wide-viewing-angle polarizer. When in use, the wide-viewing-angle polarizer can disperse the light emitted perpendicularly from the display panel 100 to increase side-viewing light, thereby improving the viewing angle. The light leakage of the display panel 100 in the dark is dispersed by the wide-viewing-angle polarizer to increase side-viewing light, thus diffusing the light leakage in the dark and preventing it from being directly seen, thereby improving the light leakage phenomenon of the display panel 100 in the dark after being impacted by external force.
[0047] like Figure 7As shown, as the fifth embodiment of this application, a display device 700 is disclosed. The display device 700 includes a driving circuit 600 and a display panel 100 as described in the above embodiment. The driving circuit 600 drives the display panel 100. In the display device of this embodiment, by setting a black matrix layer on the array substrate, and the projection of the two ends of the black matrix layer in the thickness direction of the display panel partially coincides with the first metal layer 502, that is, the black matrix layer can block the gap between the data line and the common line and the gap between the scan line and the common line. So that when the display panel is hit by an external force, even if the glass substrate on the color filter substrate side of the display panel shifts, the black matrix layer can still effectively block the gap between the data line and the common line and the gap between the scan line and the common line, and there will be no light leakage between the gap between the data line and the common line and the gap between the scan line and the common line. This improves the uneven brightness phenomenon of the display panel after being hit by an external force, thereby improving the whitening phenomenon of the display panel.
