Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a display substrate.
As shown in fig. 1, in one embodiment, the display substrate has a display area 110(AA) and a peripheral area 120, the display substrate includes a substrate and a black matrix formed on the substrate, the black matrix extends from the display area 110 to the peripheral area 120, and a portion of the black matrix located in the peripheral area 120 surrounds the display area 110.
The black matrix in the peripheral region 120 is provided with a groove penetrating the black matrix in a direction perpendicular to the substrate. In this embodiment, the slots specifically include a first slot 131 and a second slot 132, the first slot 131 extends along an edge of the display area 110, the second slot 132 is parallel to and spaced apart from the first slot 131, and the second slot 132 is located on a side of the first slot 131 away from the display area 110.
It should be understood that the edge of the display substrate needs to be sealed by a frame sealing adhesive (seal), and in order to improve the display effect, the frame of the display substrate may need to be set to be narrower, for example, the minimum distance between the frame sealing adhesive of the display substrate and the display region 110 in this embodiment is about 230 μm.
In order to prevent the frame sealing glue from fluctuating to the display region 110 and affecting the normal display effect, a PS (spacer) retaining wall needs to be arranged between the frame sealing glue and the display region 110, so that the arranged PS retaining wall may overlap with a common signal line Vcom providing a reference signal to a certain extent, and accordingly, the black matrix cannot be grooved in a region corresponding to the common signal line, which is responsible for the possible collapse of the PS retaining wall and cannot realize the function of blocking the frame sealing glue.
It is to be understood that the overlapping of two structures in the present embodiment specifically means that the orthographic projections of the two structures on the substrate overlap.
In order to avoid the adverse effect of the charges on the display substrate, an ESD (Electro-Static discharge) unit is usually disposed on the display substrate, and the ESD unit is usually disposed in the peripheral region 120 of the display substrate where no wiring is disposed.
As shown in fig. 2, in one embodiment, the display substrate includes a substrate 201, a metal trace 202, an insulating layer 203, a protective layer 204, a common signal line 205, and a black matrix 206, and a groove on the black matrix is filled with a blue resin 207.
Here, the metal trace 202 may be a driving signal line, and if the groove passes through the peripheral region where the ESD cell is disposed, there may be a certain overlap with the driving signal line, so that a small amount of the driving signal line is exposed at the groove position, and a fringe electric field may be generated between the exposed driving signal line and the common signal line, so that liquid crystal molecules in the liquid crystal layer 208 are deflected under the effect of the fringe electric field, further causing light leakage, which is specifically represented as a local blue dot display failure.
In the technical scheme of the embodiment, the orthographic projection of the slot on the substrate and the orthographic projection of the driving signal line on the substrate are controlled not to be overlapped, and the slot and the driving signal line are not overlapped by controlling the position of the slot, so that the position corresponding to the fringe electric field is the position corresponding to the black matrix but not the position corresponding to the slot, the light leakage phenomenon cannot occur in the position corresponding to the fringe electric field, and the possibility of poor display of a blue point is reduced.
In the embodiment of the present invention, by providing the first slot 131 and the second slot 132, adverse effects on the display effect caused by the entrance and accumulation of moisture carrying environmental charges can be avoided through the first slot 131 and the second slot 132, and meanwhile, by controlling the position of the first slot 131 not to overlap with the position of the driving signal line, a point defect phenomenon caused by a fringe electric field formed between the driving signal line and the common signal line can be avoided, which is helpful for improving the display effect.
It should be understood that the dimension between the second groove and the edge of the display substrate may be relatively large, and in some embodiments, in order to realize a narrow bezel, the second groove 132 is located at a position where the frame sealing adhesive wraps the groove for 130 micrometers to 170 micrometers, and more specifically, may be 150 micrometers.
In some embodiments, the minimum distance between the sealant and the display region 110 is about 230 micrometers, and the first slot 131 is disposed along the edge of the display region 110, so that the minimum distance between the first slot 131 and the second slot 132 is controlled to be 60 to 100 micrometers. In one embodiment, when the position of the second opening groove 132 is 150 micrometers for the frame sealing glue to wrap the opening groove, the minimum distance between the first opening groove 131 and the second opening groove 132 is controlled to be 80 micrometers, which can achieve both good sealing effect and narrow frame.
In some embodiments, the display area 110 includes a first linear edge extending in a first direction, a second linear edge extending in a second direction, and a transition edge between the first linear edge and the second linear edge, the transition edge extending in a curvilinear direction, wherein the first direction and the second direction intersect.
In some of the embodiments, the first direction refers to a row direction of the display substrate shown in fig. 1, and the second direction refers to a column direction of the display substrate shown in fig. 1, the first direction and the second direction being perpendicular to each other.
In this embodiment, the first straight edge refers to the lateral edges, or the upper side edge and the lower side edge, of the display area 110 shown in fig. 1, and the second straight edge refers to the longitudinal edges, or the left side edge and the right side edge, of the display area 110 shown in fig. 1.
As shown in fig. 1, in the present embodiment, the peripheral regions 120 corresponding to the first linear edge and the second linear edge are respectively provided with the first slots 131, that is, the peripheral regions 120 corresponding to the four edges extending along the straight line on the upper, lower, left and right sides of the display region 110 are respectively provided with the first slots 131.
The first notch 131 is not formed in at least a portion of the peripheral region 120 corresponding to the transition edge, where the transition edge refers to an edge located between the first edge and the second edge, and specifically, in this embodiment, the upper left corner edge, the upper right corner edge, the lower left corner edge, and the lower right corner edge of the display region 110 shown in fig. 1.
The fact that the first slot 131 is not started in at least a part of the peripheral region 120 corresponding to the transition edge means that the first slot 131 is not opened in the peripheral region 120 corresponding to at least a part of the transition edge, and the first slot 131 is started in the peripheral region 120 corresponding to at least a part of the transition edge.
Specifically, in the present embodiment, the first slot 131 is not formed in the peripheral region 120 corresponding to the transition edge of the upper left corner and the upper right corner, and the first slot 131 is formed in the peripheral region 120 corresponding to the lower left corner and the lower right corner.
In some embodiments, the display substrate has a data output end, and the transition edges include a first transition edge proximate to the data output end and a second transition edge distal to the data output end. Generally, the side close to the data output end is also referred to as the DO side of the display substrate, specifically the lower side shown in fig. 1 in the present embodiment, and the side opposite to the DO side is also referred to as the DP side, specifically the upper side shown in fig. 1 in the present embodiment.
In this embodiment, the first notch 131 is not formed in the peripheral region 120 corresponding to the second transition edge on the DP side, and the first notch 131 is formed in the peripheral region 120 corresponding to the first transition edge on the DO side.
In this embodiment, the ESD unit may be disposed in the peripheral region 120 on the DP side near the display region 110, so that the driving signal line exists in the region, and thus the first slot 131 is not opened in the region, so as to prevent the driving signal line from being exposed. In the peripheral region 120 corresponding to the first transition edge on the DP side, since there is no driving signal line, a first notch 131 may be opened in the region to isolate moisture.
In some embodiments, the first straight edge includes a first sub-edge close to the data output end and a second sub-edge far from the data output end, in this embodiment, the first sub-edge is a lower side edge of the display area 110 shown in fig. 1, and the second sub-edge is an upper side edge of the display area 110 shown in fig. 1.
The first slots 131 are continuously disposed in the peripheral region 120 corresponding to the first sub-edge, the peripheral region 120 corresponding to the first transition edge, and the peripheral region 120 corresponding to the second straight edge.
It is understood that, in the present embodiment, two first slots 131 are formed in total, wherein one first slot 131 is in a shape of a straight line, which is specifically located above in the direction shown in fig. 1, and the other second slot 132 is substantially in a shape of a U, and the first slot 131 extends from the left side of the display area 110 to the right side of the display area 110 through the lower side of the display area 110 in the peripheral area 120.
A second slot 132 is disposed on the peripheral region 120 corresponding to the second transition edge on the DP side. The second slot 132 is not opened in the peripheral region 120 corresponding to the first sub-edge. In this embodiment, the second slots 132 are continuously disposed, the second slots 132 are substantially in an inverted "U" shape, and the second slots 132 extend from the left side of the display area 110 to the right side of the display area 110 through the upper side of the display area 110 in the peripheral area 120.
It should be understood that in the present embodiment, at least one of the first slot 131 and the second slot 132 exists in each peripheral region 120 to ensure that the moisture intrusion can be effectively blocked, and the poor display caused by the exposure of the driving signal lines can be avoided by controlling the distribution positions of the first slot 131 and the second slot 132. Therefore, the second slot 132 is inevitably formed in the peripheral region 120 not formed with the first slot 131, the first slot 131 is inevitably formed in the peripheral region 120 not formed with the second slot 132, and the first slot 131 and the second slot 132 may be simultaneously formed in a part of the peripheral region 120.
