Description

Technical Field

[0001] The present invention relates to the field of display technologies, and particularly to a display panel and a display device applying the display panel. Background Art

[0002] A liquid crystal panel includes an array substrate and a color filter substrate which are oppositely arranged, liquid crystal disposed between the array substrate and the color filter substrate, and spacers for supporting. When in a low-temperature environment, both the liquid crystal and the spacers will shrink. However, since the shrinkage ability of the liquid crystal is stronger than that of the spacers, it is easy for the liquid crystal to generate low-temperature bubbles in the liquid crystal cell after shrinkage, thus resulting in poor display. Summary of the Invention

[0003] The main object of the present invention is to provide a display panel, aiming to improve the problem of bubbles appearing in the liquid crystal cell.

[0004] To achieve the above object, the display panel provided by the present invention includes an array substrate and a counter substrate oppositely arranged with the array substrate. The display panel further includes a display medium layer disposed between the array substrate and the counter substrate. The display medium layer includes a liquid crystal body and fillers. The fillers are mixed in the liquid crystal body, and the expansion and contraction ability of the fillers is less than that of the liquid crystal body.

[0005] In one embodiment, the fillers are silica gel fillers or rubber fillers;

[0006] And / or, the fillers are transparent fillers or white fillers.

[0007] In one embodiment, the weight percentage of the fillers in the display medium layer is not less than 0.5 wt% and not more than 1.5 wt%.

[0008] In one embodiment, the display panel further includes spacers disposed between the array substrate and the counter substrate. The elastic recovery ability of the fillers per unit volume is greater than that of the spacers per unit volume.

[0009] In one embodiment, the array substrate includes:

[0010] A substrate, and

[0011] A planarization layer disposed on a side of the substrate facing the liquid crystal body; and

[0012] A gas adsorption layer disposed on a side of the planarization layer away from the substrate.

[0013] In one embodiment, the gas adsorption layer is disposed adjacent to the planarization layer.

[0014] In one embodiment, the gas adsorption layer is a silica gel adsorption layer.

[0015] In one embodiment, the counter substrate includes a display area and a non-display area surrounding the display area, the non-display area is provided with a black matrix, and the black matrix is ​​mixed with gas adsorbents.

[0016] In one embodiment, the gas adsorbent is activated carbon.

[0017] The present invention further provides a display device, comprising a backlight module and the above-mentioned display panel, wherein the backlight module is arranged on a side of the array substrate away from the opposing substrate.

[0018] The technical solution of the present invention can neutralize the expansion and contraction capacity of the mixture formed by the liquid crystal body and the filler by mixing fillers in the liquid crystal body, and the expansion and contraction capacity of the filler is less than the expansion and contraction capacity of the liquid crystal body, that is, it can neutralize the expansion and contraction capacity of the display medium layer, so that the expansion and contraction capacity of the display medium layer is between the expansion and contraction capacity of the liquid crystal body and the expansion and contraction capacity of the filler. Compared with the traditional display medium layer composed only of the liquid crystal body, the expansion and contraction capacity of the display medium layer in the present invention is reduced, thereby reducing the difference between the expansion and contraction capacity of the display medium layer and the spacer, thereby improving the problem of poor bubbles caused by the contraction of the display medium layer in a low temperature environment, and also improving the poor gravity phenomenon caused by the expansion of the display medium layer in a high temperature environment, to a certain extent, widening the liquid crystal volume range and improving the display performance. In addition, when the filler has elastic properties, it can also share part of the pressure in the black gap test, thereby reducing the pressure of the spacer and reducing the risk of damage to the spacer; after the black gap test is completed, it can also assist the spacer to perform elastic recovery, shortening the elastic recovery time of the spacer.

[0032] Embodiment 1:

[0033] The present invention provides a display panel.

[0034] In the embodiments of the present invention, please refer to Figure 1 Figure (c) in Figure 2 Figure (e) in Figure 3 Figure (g) in

[0035] The display panel includes an array substrate 100 and a counter substrate 200 disposed opposite to the array substrate 100. The display panel further includes a display medium layer 300 disposed between the array substrate 100 and the counter substrate 200. The display medium layer 300 includes a liquid crystal body 310 and a filler 320. The filler 320 is mixed in the liquid crystal body 310, and the expansion and contraction ability of the filler 320 is less than that of the liquid crystal body 310.The display medium layer 300 refers to a medium layer that can control the passage or blockage of light, and is used to control the brightness of the display screen, etc. The traditional display medium layer 300 only includes the liquid crystal body 310. In the present invention, the display medium layer 300 further includes a filler 320. The filler 320 does not contain water and is an organic substance, an inorganic substance, a metal or a non-metal powder, etc. that does not have an adverse effect on other material components. After the filler 320 is added to other materials, the physical properties of other materials can be improved. In the technical solution of the present invention, by mixing the filler 320 into the liquid crystal body 310, the physical properties of the liquid crystal body 310 itself can be changed. Specifically, when the expansion and contraction ability of the filler 320 mixed in the liquid crystal body 310 is less than that of the liquid crystal body 310, the overall expansion and contraction ability of the mixture composed of the filler 320 and the liquid crystal body 310, that is, the display medium layer 300, is greater than the expansion and contraction ability of the filler 320 itself and less than the expansion and contraction ability of the liquid crystal body 310 itself. Furthermore, when in a low-temperature environment, compared with the solution where the traditional display medium layer 300 only has the liquid crystal body 310, the contraction ability of the display medium layer 300 is weaker. It can be understood that in order to ensure a uniform cell thickness, spacers 400 are also provided between the array substrate 100 and the counter substrate 200. In the technical solution of the present invention, by adding the filler 320 to the liquid crystal body 310, the expansion and contraction ability of the display medium layer 300 is reduced, so that the expansion and contraction ability of the display medium layer 300 is less different from that of the spacers 400, thereby reducing the risk of bubbles appearing in a low-temperature environment (as Figure 2 shown). In addition, please specifically refer to Figure 3 . Since the expansion ability of the display medium layer 300 is also reduced, the gravity adverse phenomenon caused by the expansion ability of the display medium layer 300 being greater than the elastic recovery ability of the spacers 400 in a high-temperature environment can be improved. With such a setting, not only can the range of the liquid crystal amount be widened to a certain extent, but also the performance of the display is improved, showing a good display effect.

[0036] In the technical solution of the present invention, in order to make the expansion and contraction ability of the filler 320 added to the liquid crystal body 310 weaker, a rigid filler 320 can be selected. It should be noted that the rigid filler 320 refers to a filler 320 with a rigid molecular structure. For example, groups with benzene rings, polycyclic rings, and triple bonds are rigid groups. The rigid filler 320 can be made of silica gel, rubber materials, etc. On the other hand, the rigid filler 320 in the technical solution of the present invention also has certain elastic properties, and it can assist the spacers 400 in elastic recovery. As Figure 1As shown, for example, in the black gap test (the black gap test is a type of stress test. When the panel is externally squeezed, the spacers are compressed. Within the elastic recovery limit, if the external force is removed, they will return to the initial state, and the height of the columnar spacers remains unaffected. If the external force is large and lasts for a long time, exceeding the elastic recovery limit of the spacers, a black gap phenomenon will occur), since pressure needs to be applied to the counter substrate 200 for a period of time, the spacers 400 play a major supporting role. In the technical solution of the present invention, since the filler 320 is mixed in the liquid crystal body 310, this filler 320 can also share part of the pressure, thereby reducing the pressure on the spacers 400 and further reducing the risk of damage to the spacers 400. On the other hand, when the black gap test ends, the filler 320 can exert its own elastic recovery ability, thereby assisting the spacers 400 in elastic recovery to a certain extent, and sharing part of the elastic recovery process of the spacers 400, shortening the elastic recovery time of the spacers 400.

[0037] In the technical solution of the present invention, by mixing the filler 320 in the liquid crystal body 310 and the expansion and contraction ability of the filler 320 being less than that of the liquid crystal body 310, the expansion and contraction ability of the mixture formed by the liquid crystal body 310 and the filler 320 can be neutralized, that is, the expansion and contraction ability of the display medium layer 300 can be neutralized. Furthermore, the expansion and contraction ability of the display medium layer 300 is made to be between the expansion and contraction ability of the liquid crystal body 310 and the expansion and contraction ability of the filler 320. Compared with the traditional display medium layer 300 composed only of the liquid crystal body 310, the expansion and contraction ability of the display medium layer 300 in the present invention is reduced, thereby reducing the difference in the expansion and contraction ability between it and the spacers 400. Furthermore, the problem of bubble defects caused by the contraction of the display medium layer 300 in a low-temperature environment is improved, and the gravity defect phenomenon caused by the expansion of the display medium layer 300 in a high-temperature environment can also be improved. To a certain extent, the liquid crystal amount range is broadened and the display performance is improved. In addition, when the filler 320 has elastic properties, it can also share part of the pressure in the black gap test, thereby reducing the pressure on the spacers 400 and reducing the risk of damage to the spacers 400; when the black gap test ends, it can also assist the spacers 400 in elastic recovery, shortening the elastic recovery time of the spacers 400.

[0038] In one example, the filler 320 is a silica gel filler 320 or a rubber filler 320.

[0039] By setting the filler 320 as a silica gel filler 320 or a rubber filler 320, on the one hand, it can ensure that the expansion and contraction ability of the filler 320 is less than that of the liquid crystal body 310, so as to neutralize the expansion and contraction ability of the mixture formed by the liquid crystal body 310 and the filler 320, that is, it can neutralize the expansion and contraction ability of the display medium layer 300. Furthermore, the expansion and contraction ability of the display medium layer 300 is made to be between the expansion and contraction ability of the liquid crystal body 310 and the expansion and contraction ability of the filler 320. Compared with the conventional display medium layer 300 composed only of the liquid crystal body 310, the expansion and contraction ability of the display medium layer 300 in the present invention is reduced, thereby reducing the difference in the expansion and contraction ability between it and the spacer 400. Furthermore, it improves the problem of defective bubbles caused by the contraction of the display medium layer 300 in a low-temperature environment, and can also improve the gravity defect phenomenon caused by the expansion of the display medium layer 300 in a high-temperature environment, and to a certain extent, broadens the liquid crystal amount range and improves the display performance. On the other hand, by setting the filler 320 as a silica gel filler 320 or a rubber filler 320, the filler 320 also has good elastic properties, so that it can share part of the pressure of the spacer 400 in the black gap test, reducing the pressure on the spacer 400 and reducing the risk of damage to the spacer 400; when the black gap test is over, the silica gel filler 320 can assist the spacer 400 in elastic recovery, shortening the elastic recovery time of the spacer 400.

[0040] In one example, the weight percentage of the filler 320 in the display medium layer 300 is not less than 0.5 wt% and not more than 1.5 wt%.

[0041] Specifically, the weight percentage of the filler 320 in the display medium layer 300 can be 0.5 wt%, 0.6 wt%, 0.7 wt%, 0.8 wt%, 0.9 wt%, 1.0 wt%, 1.1 wt%, 1.2 wt%, 1.3 wt%, 1.4 wt% or 1.5 wt%. By setting the weight percentage of the filler 320 in the display medium layer 300 to be not less than 0.5 wt%, the filler 320 mixed in the liquid crystal body 310 will not be too little, thus avoiding the situation that too little addition of the filler 320 results in no obvious improvement in the expansion and contraction ability of the display medium layer 300. By setting the weight percentage of the filler 320 in the display medium layer 300 to be not more than 1.5 wt%, it avoids the situation that too much addition of the filler 320 affects the fluidity and the ability of thermal expansion and contraction of the liquid crystal body 310. In addition, it can also avoid affecting the display effect due to too much addition of the filler 320.

[0042] Furthermore, the filler 320 can be a transparent filler 320 or a white filler 320, etc. By setting the filler 320 as a transparent filler 320 or a white filler 320, the influence of the filler 320 on the display effect can be reduced, and the occurrence of defects such as black dots on the display screen can be avoided.

[0043] In one example, as shown in Figure 1 Figure (c) of [], the display panel further includes spacers 400 disposed between the array substrate 100 and the counter substrate 200, and the elastic recovery ability of the filler 320 per unit volume is greater than that of the spacer 400 per unit volume.

[0044] By further providing spacers 400 between the array substrate 100 and the counter substrate 200, when an external force acts on the counter substrate 200, the spacers 400 play a main supporting effect. A plurality of spacers 400 are provided at intervals, thereby improving the ability to resist external forces and dispersing the pressure received by each spacer 400, reducing the risk of damage to the spacers 400. In addition, based on the solution in which the filler 320 is mixed in the liquid crystal body 310 of the display medium layer 300, when the filler 320 has elastic properties, it can also share part of the pressure, thereby further reducing the pressure received by the spacers 400 and reducing the risk of damage to the spacers 400. In this example, by making the elastic recovery ability of the filler 320 per unit volume greater than that of the spacer 400 per unit volume, the spacer 400 can be better assisted to recover from deformation after being compressed, or the counter substrate 200 can be assisted to return to a state closer to the initial position after the spacer 400 is damaged. Specifically, when the filler 320 adopts the above-mentioned silicone filler 320 or rubber filler 320, it has better elastic recovery ability, ensuring that the elastic recovery ability of the filler 320 per unit volume is greater than that of the spacer 400 per unit volume.

[0045] In one example, as shown in Figure 4 Figure [], the array substrate 100 includes a substrate 150, a planarization layer 120, and a gas adsorption layer 130. The planarization layer 120 is disposed on the side of the substrate 150 facing the liquid crystal body 310; the gas adsorption layer 130 is disposed on the side of the planarization layer 120 away from the substrate 150.

[0046] The array substrate 100 includes a substrate 150, which provides a setting basis for setting metal wires or other film layers. A thin film transistor 110, a planarization layer 120, an alignment film 140, etc. are provided on the substrate 150, and the planarization layer 120 is disposed between the thin film transistor 110 and the alignment film 140. By providing the planarization layer 120 on the array substrate 100, on the one hand, it can protect the thin film transistor 110, and on the other hand, it also plays a planarization role. In a high-temperature environment, the planarization layer 120 will volatilize gas, and the gas enters the liquid crystal cell between the array substrate 100 and the counter substrate 200, thereby causing bubbles to be generated in the liquid crystal cell. The array substrate 100 in the technical solution of the present invention further includes a gas adsorption layer 130 disposed on a side of the planarization layer 120 away from the substrate 150, so that the gas adsorption layer 130 can isolate the gas from entering the liquid crystal cell when the planarization layer 120 generates volatile gas, reducing the risk of bubbles being generated in the liquid crystal cell due to the volatile gas generated by the planarization layer 120 entering the liquid crystal cell in a high-temperature environment. It should be noted that the gas adsorption layer 130 disposed on a side of the planarization layer 120 away from the substrate 150 in this example may mean that the gas adsorption layer 130 is adjacent to the planarization layer 120, that is, the gas adsorption layer 130 is in contact with the planarization layer 120; or it may also mean that there is other film layer between the gas adsorption layer 130 and the planarization layer 120, as long as the effect of isolating the volatile gas from entering the liquid crystal cell when the planarization layer 120 generates volatile gas can be achieved.

[0047] Further, as Figure 4 shown, the gas adsorption layer 130 is adjacent to the planarization layer 120.

[0048] By disposing the gas adsorption layer 130 adjacent to the planarization layer 120, the gas adsorption layer 130 can adsorb the volatile gas from the source, thereby preventing the volatile gas from entering the liquid crystal cell from the source.

[0049] In an example, the gas adsorption layer 130 is a silica gel adsorption layer.

[0050] By setting the gas adsorption layer 130 as a silica gel adsorption layer, on the one hand, it can ensure that it can effectively adsorb the volatile gas generated by the planarization layer 120, and on the other hand, after the gas adsorption layer 130 adopts a silica gel adsorption layer, the gas adsorption layer 130 can be presented as transparent or milky white, so that the gas adsorption layer 130 has a small impact on the display effect of the display panel, ensuring that the display panel still has a good display effect.

[0051] Further, as Figure 5As shown, the counter substrate 200 includes a display area 201 and a non-display area 202 surrounding the display area 201. A black matrix 210 is provided in the non-display area 202, and a gas adsorbent is mixed in the black matrix 210.

[0052] In order to form a closed cavity in the liquid crystal cell, a sealant 500 is further provided between the counter substrate 200 and the array substrate 100. In this example, the counter substrate 200 includes a display area 201 and a non-display area 202. The display medium layer 300 is provided corresponding to the display area 201 of the counter substrate 200, and the sealant 500 is provided corresponding to the non-display area 202 of the counter substrate 200 to seal the display medium layer 300 in a closed space. In order to ensure that there is no light leakage in the non-display area 202, a black matrix 210 is provided in the non-display area 202 of the counter substrate 200. However, due to process reasons, the sealant 500 may not be able to completely seal the display medium layer 300, so some gases may enter the liquid crystal cell, resulting in bubbles in the liquid crystal cell. In this example, by mixing a gas adsorbent in the black matrix 210, the gases passing through the gap between the sealant 500 and the counter substrate 200 can be adsorbed by the gas adsorbent mixed in the black matrix 210, thereby preventing the gases from entering the liquid crystal cell through the gap between the sealant 500 and the counter substrate 200, and thus reducing the risk of generating bubbles in the liquid crystal cell and improving the display effect of the display panel.

[0053] Of course, in other embodiments, the gas adsorbent can also be coated on the side of the black matrix 210 in the non-display area 202 facing the sealant 500, so that the gas adsorbent can be closer to the sealant 500 to adsorb the gases passing through the gap between the sealant 500 and the counter substrate 200 in a timely manner.

[0054] In one example, the gas adsorbent is activated carbon.

[0055] By setting the gas adsorbent as activated carbon, on the one hand, the gas adsorbent has a porous structure, so that the gas adsorbent can have a better adsorption effect on gases. On the other hand, when the gas adsorbent is activated carbon, the gas adsorbent is black, so that it can have a good light-shielding effect and further reduce the risk of light leakage in the non-display area 202 of the counter substrate 200.

[0056] Embodiment 2:

[0057] The present invention also provides a display device, such as Figure 6As shown, the display device includes a backlight module 600 and a display panel. For the specific structure of the display panel, refer to the above embodiments. Since this display device adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here. Among them, the backlight module 600 is disposed on the side of the array substrate 100 away from the counter substrate 200.

[0058] When the display panel includes a liquid crystal body 310, since the liquid crystal body 310 itself cannot emit light, a separate light source needs to be provided to enable the display panel to display an image. The backlight module 600 is the module that provides the light source. By disposing the backlight module 600 on the side of the array substrate 100 away from the counter substrate 200, that is, the backlight module 600 is disposed on the light incident side of the display panel, a stable light source can be provided for the display panel, ensuring that the light can display an image on the counter substrate 200 after passing through the display medium layer 300 for the user to view. Specifically, the backlight module 600 can be a direct-lit backlight module 600 or an edge-lit backlight module 600. When the backlight module 600 is a direct-lit backlight module 600, the light emitted by the light source in the backlight module 600 is emitted almost perpendicular to the array substrate 100; when the backlight module 600 is an edge-lit backlight module 600, the light source in the backlight module 600 is disposed on the side, and a light guide plate is also provided in the backlight module 600 to convert the laterally emitted light into light in the direction perpendicular to the array substrate 100.

[0059] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
