Detailed Description

In the description of the present application, the term "plurality" means two or more. The terms "comprises," "comprising," and any variations thereof, are intended to cover a non-exclusive inclusion, such that one or more other features, integers, steps, operations, elements, components, and/or groups thereof may be present or added.

The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.
Spacers (PS, photo spacers/film columns) are located between a first substrate (color film substrate) and a second substrate (array substrate) of the liquid crystal display panel, for controlling the distance and uniformity between the first substrate and the second substrate; as shown in fig. 1 and 4-8, which are schematic diagrams of several distributions of the main spacers in the composite spacers, the inventors found that the main spacers in the composite spacers are prone to spalling (as shown in fig. 2 and 3), affect in-process detection, even spacer function, and are sensitive to variations in machine production parameters.
The invention is further described below with reference to the drawings and alternative embodiments.
As shown in fig. 4 to 15, the embodiment of the present invention discloses a display panel 110, wherein the display panel 110 includes a first substrate 117, a second substrate 118, and a spacer 112, and the second substrate 118 is disposed opposite to the first substrate 117; the spacer 112 is formed on the first substrate 117 and is located between the first substrate 117 and the second substrate 118; the spacers 112 comprise a combined spacer 119, the combined spacer 119 comprising a secondary spacer 113 and at least two primary spacers 114, the secondary spacer 113 being connected to the primary spacers 114. Compared with the scheme in fig. 1, the scheme increases the integrity of the combined spacer 119 by adding the auxiliary spacer 113 beside the main spacer 114 in the combined spacer 119, so that the auxiliary spacer 113 is connected with the main spacer 114; the auxiliary spacers 113 can fix and strengthen the main spacers 114 and improve the peeled-off objects 116 of the main spacers 114; and the auxiliary spacers 113 play an auxiliary role on the main spacers 114, so that the normal use of the main spacers 114 is not affected.
Wherein fig. 5 is a schematic diagram of a partial distribution of the main spacers 114 in the combined spacers 119, which can be understood in conjunction with the distribution of the spacers 112 in fig. 1.
As shown in fig. 6 to 8, in an embodiment, the first substrate 117 includes a substrate 122, a black matrix 120 and a color resist layer 121, wherein the black matrix 120 and the color resist layer 121 are both formed on the substrate 122, and the black matrix 120 is connected to the color resist layer 121, and wherein the spacers 112 are directly fixed on the black matrix 120 or on the color resist layer 121. It should be noted that the present application is also applicable to spacers provided at other positions in a display panel, and can solve the problem of peeling of the corresponding spacers.
As shown in fig. 4 and 9, in one embodiment, the shape of the auxiliary spacer 113 is polygonal. Considering that the distribution shapes of the main spacers 114 are different, the shapes of the auxiliary spacers 113 are polygonal, so that the auxiliary spacers 113 can adapt to various distribution shapes and can be conveniently arranged beside the main spacers 114 with different distribution shapes, the auxiliary spacers 113 can be better matched with the main spacers 114, and accordingly the stripped objects 116 of the main spacers 114 are effectively improved, and meanwhile, the polygonal auxiliary spacers 113 are more suitable for environments, so that the difficulty of a manufacturing process is relatively reduced.
As shown in fig. 9 to 12, in an embodiment, the height of the auxiliary spacers 113 is lower than the height of the main spacers 114. Because the main spacer 114 has a supporting function, if the height of the auxiliary spacer 113 is set to be higher than or equal to the height of the main spacer 114, the function of the main spacer 114 is affected, so that the height of the auxiliary spacer 113 is set to be lower than the height of the main spacer 114, and thus the peeled-off object 116 of the main spacer 114 can be improved without affecting the normal function of the main spacer 114.
In an embodiment, the height of the auxiliary spacers 113 is not less than half the height of the main spacers 114 and not more than two-thirds of the height of the main spacers 114. The inventors found that when the height of the auxiliary spacer 113 is set within the interval of half to two thirds of the height of the main spacer 114, it improves the spalled object 116 of the main spacer 114, and the auxiliary spacer 113 within the height range does not adversely affect the normal function of the main spacer 114, and at the same time, the auxiliary spacer 113 can relatively strengthen the structure of the main spacer 114.
As shown in fig. 10 and 12, in one embodiment, the shape of the auxiliary spacer 113 is an arc. Considering that the surface of the main spacer 114 is generally arc-shaped, in order to make the auxiliary spacer 113 better adhere to the main spacer 114, the shape of the auxiliary spacer 113 is set to be arc-shaped, and when the auxiliary spacer 113 is adhered to the main spacer 114, the auxiliary spacer 113 is fixed more firmly, and can protect the surface of the main spacer 114 better, so that the spalled matter 116 of the main spacer 114 can be improved effectively.
As shown in fig. 11, in one embodiment, the shape of the auxiliary spacers 113 is cross-shaped. The cross-shaped auxiliary spacer 113 has better stability on the structure, can be better fixed with the main spacer 114, thereby improving the stripping object 116 of the main spacer 114, and has large occupied ratio of effective functional parts of the cross-shaped auxiliary spacer 113, thus having high material utilization rate and low cost and being suitable for the main spacers which are distributed relatively in a cross manner.
In one embodiment, the secondary spacer 113 includes a leg 115, and the leg 115 is connected to the primary spacer 114. Because the distribution shapes of the main spacers 114 are different, the branch parts 115 of the scheme can reduce the waste of the materials of the auxiliary spacers 113 and improve the utilization rate of the materials; but also improves the spalling 116 of the primary spacer 114, and the legs 115 strengthen the primary and secondary spacers 114, 113.
In one embodiment, the number of the branches 115 corresponds to the number of the main spacers 114, and is connected in a one-to-one correspondence. This is applicable to any shape distribution of the combined main spacers 114, and each main spacer 114 has a corresponding auxiliary spacer 113 to assist, so that the peeled-off object 116 of each main spacer 114 can be improved, and the utilization efficiency of the branch 115 is high.
Wherein, for the polygonal auxiliary spacer 113, each corner thereof is the branch 115; for oval secondary spacers 113, the more pointed end is the leg 115; the protruding portion of the intersecting secondary spacers 113 is the leg 115.
Of course, the auxiliary spacer 113 may be formed in other shapes, for example, a combination of a polygon and an arc, or some design for increasing the number of the auxiliary spacers, so long as the auxiliary spacer can be used as desired.
As shown in fig. 13 and 14, in one embodiment, the overlapping surface between the auxiliary spacer 113 and each of the main spacers 114 is closed. The overlapping surface between the auxiliary spacer 113 and each main spacer 114 is closed, that is, the auxiliary spacer 113 connects each group of main spacers 114 and forms a surrounding for each main spacer 114, so that peeling of the main spacers 114 in various directions can be improved, and the auxiliary spacer 113 plays a role in reinforcing and fixing each main spacer 114, so that the performance of the main spacers 114 is more stable.
As shown in fig. 14, in an embodiment, the auxiliary spacers 113 are disposed in one-to-one correspondence with each of the main spacers 114. The auxiliary spacers 113 are arranged in one-to-one correspondence with each main spacer 114, so that the peeling of each main spacer 114 can be improved without omission; in addition, in the one-to-one arrangement, for the area which does not need the auxiliary spacers 113 to improve, the auxiliary spacers 113 are not needed, so that the material utilization efficiency of the auxiliary spacers 113 is higher; meanwhile, each auxiliary spacer 113 only plays an auxiliary role on its corresponding main spacer 114, so that the functions of the auxiliary spacers 113 are more concentrated and the peeling improvement effect on the main spacers 114 is better.
As shown in fig. 15, in one embodiment, the secondary spacers 113 are disposed between adjacent primary spacers 114. The inventor finds that the area between the adjacent main spacers 114 has more spalling 116, so the auxiliary spacers 113 are arranged between the adjacent main spacers 114 in the scheme, so that the spalling between the adjacent main spacers 114 can be effectively improved, the influence of the spalling 116 on the main spacers 114 is greatly reduced, and the utilization rate of the auxiliary spacers 113 is relatively higher.
In one embodiment, the overlapping surface between the auxiliary spacer 113 and each of the main spacers 114 is closed, and the auxiliary spacers 113 are disposed between adjacent main spacers 114. The overlapped surfaces between the auxiliary spacers 113 and each main spacer 114 are closed, that is, the auxiliary spacers 113 connect each group of main spacers 114 and form a surrounding for each main spacer 114, so that the peeling of the main spacers 114 in all directions can be improved, and the auxiliary spacers 113 play a role in reinforcing and fixing the main spacers 114, so that the performance of the main spacers 114 is more stable; the inventor finds that the area between the adjacent main spacers 114 has more spalling 116, so the auxiliary spacers 113 are arranged between the adjacent main spacers 114 in the scheme, so that the spalling between the adjacent main spacers 114 can be effectively improved, the influence of the spalling 116 on the main spacers 114 is greatly reduced, and the utilization rate of the auxiliary spacers 113 is relatively higher.
As shown in fig. 4 to 14, the present invention also discloses a display panel 110, wherein the display panel 110 includes a first substrate 117, a second substrate 118, and a spacer 112, and the second substrate 118 is disposed opposite to the first substrate 117; the spacer 112 is formed on the first substrate 117 and is located between the first substrate 117 and the second substrate 118; the spacers 112 include a combined spacer 119, the combined spacer 119 including a subsidiary spacer 113 and at least two main spacers 114, the subsidiary spacer 113 being connected to the main spacers 114; the shape of the auxiliary spacer 113 is polygonal, arc-shaped or cross-shaped; the height of the auxiliary spacers 113 is not less than half the height of the main spacers 114 and not more than two thirds of the height of the main spacers 114; the auxiliary spacers 113 include branch portions 115, the number of the branch portions 115 corresponds to the number of the main spacers 114, and the branch portions 115 are connected with the main spacers 114 in a one-to-one correspondence; the overlapping surface between the auxiliary spacer 113 and each of the main spacers 114 is closed. By additionally arranging the auxiliary spacer 113 beside the main spacer 114 in the combined spacer 119, the auxiliary spacer 113 is connected with the main spacer 114, so that the integrity of the combined spacer is improved, the main spacer 114 can be fixed and reinforced, and the stripping object 116 of the main spacer 114 is improved; considering that the distribution shapes of the main spacers 114 are different, the shapes of the auxiliary spacers 113 are polygonal, arc-shaped or cross-shaped, so that the auxiliary spacers can adapt to various distribution shapes, the stripped objects 116 of the main spacers 114 can be effectively improved, and the difficulty of a manufacturing process is relatively reduced; the inventors found that when the height of the auxiliary spacer 113 is set in the interval of half to two thirds of the height of the main spacer 114, it is preferable to improve the peeled-off material 116 of the main spacer 114; the number of the branch parts 115 is corresponding to the number of the main spacers 114 and is connected in a one-to-one correspondence manner, so that the stripping object 116 of each main spacer 114 can be improved, and the utilization efficiency of the branch parts 115 is high; the overlapping surface between the auxiliary spacer 113 and each main spacer 114 is closed, that is, the auxiliary spacer 113 connects each group of main spacers 114 and forms a surrounding for each main spacer 114, so that peeling of the main spacers 114 in various directions can be improved, and the auxiliary spacer 113 plays a role in reinforcing and fixing each main spacer 114, so that the performance of the main spacers 114 is more stable.
