Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The invention provides a solution for solving the problem of residual stress after box alignment caused by uneven thickness of a substrate film layer in the prior art.
In one aspect, an embodiment of the present invention further provides a display panel, as shown in fig. 1, including a display substrate 1 and a pair-box substrate 2 disposed in a pair of boxes. Wherein, the display substrate 1 is provided with at least a first part A and a second part B with different thicknesses on the side facing the opposite box substrate 2, and the thickness of the first part A on the display substrate 1 is smaller than that of the second part B on the display substrate 1. That is, the display substrate 1 has a problem that the thickness of the film is not uniform as in the prior art.
Correspondingly, the pair of cassette substrates 2 includes:
the dual-functional-layer liquid crystal display comprises a substrate base plate 21 and a dual-functional-layer-box 22 formed on the substrate base plate 21, wherein the dual-functional-layer-box 22 comprises a third part C and a fourth part D which are different in thickness, and the thickness of the third part C is smaller than that of the fourth part D;
after the box aligning substrate 2 and the display substrate 1 are aligned, the forward projection of the third part C on the display substrate 1 and the forward projection of the first part A on the display substrate 1 have an overlapping region, that is, the third part C of the box aligning substrate 2 is opposite to the first part A of the display substrate 1; similarly, the forward projection of the fourth portion D on the display substrate 1 and the forward projection of the second portion B on the display substrate 1 have an overlapping region, that is, the fourth portion D of the pair of cell substrates 2 faces the second portion B of the display substrate 1.
It can be seen that this embodiment sets up the box functional layer to on the box base plate, this thickness to the box functional layer has corresponding relation with display substrate's rete thickness, to box base plate and display substrate after to the box promptly, to the thinner region of box base plate just to the thicker region of display substrate, to the thicker region of box base plate just to the thinner region of display substrate, based on this design, make to box base plate and display substrate offset the influence that the box thickness is inconsistent bringing to the box in-process, thereby after accomplishing the box, effectively reduce remaining stress, guarantee that display panel does not take place great deformation and influence normal demonstration.
For example, assuming that the display substrate is a lower substrate, a MASK is disposed at an edge region of the display substrate in a conventional manufacturing process, that is, a functional layer of the display substrate needs to avoid the MASK region, so that a thickness of a film layer in a central region is greater than that in the edge region.
Therefore, in the present embodiment, assuming that the distance between the third portion C and the center of the opposing substrate 2 is greater than the distance between the fourth portion D and the center of the display substrate, the thickness of the third portion is greater than that of the fourth portion, and thus corresponds to the display substrate.
In practical applications, the display substrate has a maximum thickness of a film layer in a display central region (typically, a display device such as a thin film transistor, a pixel electrode, and a signal line is provided), a display edge region surrounding the display central region (typically, a signal line is provided), and a non-display region surrounding the display edge region (typically, a MASK is provided).
Accordingly, as shown in fig. 2, the average thickness of the pair-cell functional layer 21 of the pair-cell substrate in the display central region Z-Z is smaller than the average thickness of the pair-cell functional layer 21 in the display edge region Y-Z, Z x-Y; the average thickness of the pair-cell functional layer 21 located at the display edge region Y-Z, Z X-Y is smaller than the average thickness of the pair-cell functional layer 21 located at the non-display region X-Y, Y X.
Preferably, in addition to the above, as shown in fig. 3, in the pair-cell substrate of the present embodiment, the thickness of the pair-cell functional layer 21 in the display central region Z-Z is equal at all locations, and the thickness of the pair-cell functional layer 21 in the non-display region X-Y, Y-X is equal at all locations; the thickness of the pair-cell functional layer in the bit display edge region Y-Z, Z-Y gradually increases from near the center of the pair-cell substrate 21 to far from the center of the pair-cell substrate 21.
Based on this structural design, the slope of the display central region Z-Z and the non-display region X-Y, Y-X of the cell substrate 21 is relatively gentle, so that uniform pressure is applied to the display central region and the non-display region of the display substrate during cell alignment, which is more helpful for image display.
In addition, as shown in fig. 4, in practical applications, the pair-box functional layer 21 of the present embodiment may be composed of a plurality of functional patterns 211, and in the display edge region Y-Z, Z-Y, assuming that the distance between the first functional pattern and the center of the pair-box substrate is greater than the distance between the second functional pattern and the center of the pair-box substrate, the thickness of the first functional pattern is greater than the thickness of the second functional pattern. Therefore, taking the edge region Y-Z, Z-Y shown in fig. 4 as an example, the edge region Y-Z, Z-Y can be formed by a plurality of functional patterns 211 in a manner similar to integration to form a gentle slope structure.
In addition, in order to further make the pair-box functional layer 21 have a smooth surface, as shown in fig. 5, the pair-box substrate of the present embodiment further includes:
the insulating layer 23 covering the pair-box functional layer 21 is based on the different thicknesses of the pair-box functional layer 21 to form a smooth end surface (the smooth end surface is not planar but has a curvature) within the display edge region Y-Z, Z-Y. Obviously, the provision of the insulating layer 23 can further improve the smoothness of the side of the cell substrate facing the display substrate, and can prevent uneven stress from being applied to the display substrate during the cell alignment process.
In a specific implementation, the thickness gradient of the cell function layer of the cell-on-cell substrate of this embodiment may be set according to the cell thickness gradient of the display substrate, for example, the cell thickness gradient of the display substrate in the display edge region Y-Z, Z × Y is 85 μm/7.5mm, and the display edge region Y-Z, Z × Y of the cell-on-cell substrate is consistent with the display substrate, which is also 0.85 μm/7.5 mm.
The cartridge substrate of the present embodiment will be described in detail with reference to one implementation.
In an implementation manner, if the opposing substrate is a color film substrate, the display substrate aligned with the opposing substrate is an array substrate.
Referring to fig. 6, the pair-box functional layer of the color filter substrate is specifically an existing color filter layer 22, and correspondingly, the functional pattern constituting the pair-box functional layer is a color resistance pattern in the color filter layer 22. The color resistance patterns comprise a red color resistance pattern R, a green color resistance pattern G and a blue color resistance pattern B, and the color resistance patterns of different colors are shielded by a black matrix 24 arranged on the color film substrate.
Preferably, the thickness of the color filter layer 22 is 1.7 micrometers to 2.5 micrometers, that is, the color resistance pattern R, G, B is in a range of 1.7 micrometers to 2.5 micrometers, and gradually becomes thicker in a direction away from the central area of the color filter substrate.
Continuous practice proves that the thickness of the color filter layer 22 of the embodiment varies within a range of 1.7 micrometers to 2.5 micrometers, which can ensure that the color filter layer 22 further meets the requirement of the array substrate for the box on the premise of realizing the traditional filtering function.
It can be seen that in this implementation manner, the pair-box functional layer of the color filter substrate is reused as the existing color filter layer, so that a new manufacturing process is not additionally added on the basis of the existing manufacturing process in the implementation of the scheme of this embodiment, that is, the manufacturing cost of the color filter substrate is not additionally increased in the scheme of this embodiment.
In addition, referring to fig. 6, in the conventional color filter substrate, an insulating layer 23 covering the color filter layer 22 needs to be provided, and a spacer (the spacer is an existing pattern) required for cassette assembly needs to be subsequently provided on the insulating layer 23, so that the insulating layer 23 of the color filter substrate of this embodiment can further increase the smoothness of the color filter substrate toward the array substrate.
The above is the introduction of the implementation manner, and it can be seen that, compared with the prior art, the implementation manner can reduce the residual stress after the color film substrate and the array substrate are boxed into the display panel only by changing the thickness of the color resistance graph of the color film substrate.
It should be noted that, the pair box substrate and the display substrate of the present embodiment are distinguished only by different names, and as an example, the pair box substrate of the present embodiment may be an array substrate, and the display substrate may be a color filter substrate, that is, the present embodiment may form a pair box functional layer on the array substrate to meet the pair box requirement of the array substrate and the color filter substrate. Since the principle is the same, the description is not repeated herein by way of example.
In addition, in practical applications, there may be a plurality of regions with uneven thicknesses on the display substrate of the display panel, and therefore, the pair-box functional layer of the pair-box substrate may also have regions with different thicknesses.
On the other hand, the embodiment of the invention also provides a display device, which comprises the display panel provided by the invention.
Referring to fig. 7, fig. 7 is a schematic diagram illustrating a display of a conventional display device for yellow, wherein the left side of a dotted line indicates a display edge area, the right side of the dotted line indicates a display center area, and an ordinate indicates a yellow intensity coefficient of a display screen.
Further, referring to fig. 8, fig. 8 is a schematic diagram of a display of the display device of this embodiment for yellow, as with fig. 7, where the left side of the dotted line represents a display edge region, the right side of the dotted line represents a display center region, and the ordinate represents a yellow intensity coefficient of a display screen, as can be seen from fig. 8, the yellow intensity of the display device of this embodiment in the display edge region and the yellow intensity of the display center region are approximately consistent, and belong to a normal range, and the phenomenon of yellowing around the existing display device has been solved.
In practical applications, the display device of the embodiment may be a product with a display panel, such as a mobile phone, a tablet computer, a television, a watch, and the like.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
