Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a National Stage Entry of
PCT/CN2016/086712 filed on Jun. 22, 2016, which claims the benefit
and priority of Chinese Application No. 201620190763.1 filed on
Mar. 14, 2016, the disclosures of which are incorporated by
reference herein in their entirety as part of the present
application.
BACKGROUND
[0002] The present disclosure relates to the field of display, and
more particularly, to a display panel and a display device.
[0003] The liquid crystal display panel is usually composed of
upper substrate and lower substrates and a backlight source, in
which the upper and lower substrates are generally a color film
substrate and an array substrate. In the case where the alignment
is good, the light from the backlight source passes through a
filter layer for display of the color film substrate, thereby
displaying a screen.
[0004] The array substrate and the color film substrate of the
liquid crystal display panel tend to be displaced in the X
direction (i.e., the direction parallel to the array substrate
and/or the color film substrate) so that the primary color portions
in the color film substrate and the portion of the array substrate
for display have displacement deviation, so that when the backlight
is irradiated to the array substrate, the liquid crystal display
panel is prone to light leakage, color mixing and other undesirable
phenomena. This occurs mainly in the following two scenarios:
[0005] 1) In the manufacture process of the liquid crystal panel,
when the sealing rubber between the array substrate and the color
film substrate is not cured, and during the processing and
transportation process of the liquid crystal panel; and
[0006] 2) After completion of the manufacture of the liquid crystal
panel, extrusion and bending (such as touching) from the Y
direction results in local deformation of the glass substrate, and
after the deformation is restored it is possible to form a
misalignment between the array substrate and the color film
substrate.
[0007] It can be seen that there is a need in the art for a
solution that overcomes the displacement between upper and lower
substrates of the display panel.
BRIEF DESCRIPTION
[0008] An embodiment of the present disclosure provides a display
panel, including a first substrate and a second substrate disposed
opposite to each other, wherein at least one restriction region is
formed by a wiring pattern in a peripheral area of the first
substrate, and one or more spacers are provided on the second
substrate corresponding to the restriction region, the spacers
forming restriction with the wiring pattern in at least one
direction parallel to the substrates.
[0009] According to an exemplary embodiment of the present
disclosure, the forming restriction in at least one direction
parallel to the substrates includes forming restriction in at least
two directions.
[0010] According to an exemplary embodiment of the present
disclosure, the wiring pattern includes a wiring and/or a mark line
pattern, the wiring including at least one of a gate line lead
wire, a data line lead wire, a common electrode lead wire, an
electrostatic protection ring, and a repair line.
[0011] According to an exemplary embodiment of the present
disclosure, the at least one restriction region includes a gap
between at least two parallel and/or intersecting wires.
[0012] According to an exemplary embodiment of the present
disclosure, the at least one restriction region is formed by a bend
portion of a single wire.
[0013] According to an exemplary embodiment of the present
disclosure, the spacers are provided at least two different
restriction regions, the spacers and the different restriction
regions performing restriction in at least two different directions
parallel to the substrates.
[0014] According to an exemplary embodiment of the present
disclosure, the angle between the two different directions is
90.degree. or 180.degree..
[0015] According to an exemplary embodiment of the present
disclosure, at least one spacer is provided on the second substrate
at a position corresponding to the wiring in the peripheral area of
the first substrate.
[0016] According to an exemplary embodiment of the present
disclosure, at least a portion of the spacers are different in
shape or size depending on different restriction regions.
[0017] Another embodiment of the present disclosure provides a
display device including a display panel according to any one of
the above embodiments.
[0018] The technical solution of the present disclosure can
effectively prevent the occurrence of misalignment between the
upper and lower substrates of a display panel, thereby avoiding the
occurrence of light leakage, color mixing and other undesirable
phenomena. Further, by using a restriction region formed by wiring
in the peripheral area of the first substrate and spacers provided
on the second substrate to form a restriction structure, the
solution of the present disclosure is simple in structure and
inexpensive.

DETAILED DESCRIPTION
[0025] The display panels provided in embodiments of the present
disclosure will now be described in further detail with reference
to the accompanying drawings and specific embodiments in order to
provide a better understanding of the technical solutions of the
present disclosure by those skilled in the art. It is obvious that
the described embodiments are part of the present application, not
all embodiments. All other embodiments obtained by one of ordinary
skill in the art based on the described embodiments of the present
disclosure without paying creative effort are within the scope of
this disclosure.
[0026] Embodiments of the present disclosure will now be described
with reference to the accompanying drawings. FIG. 1 shows a
cross-sectional view of a display panel according to an embodiment
of the present disclosure. FIG. 2 shows a plan view of a display
panel according to an embodiment of the present disclosure.
[0027] As shown in the drawing, according to an embodiment of the
present disclosure, the display panel may include a first substrate
1 and a second substrate 2 disposed opposite to each other, and at
least one restriction region 4 may be formed in a peripheral area
of the first substrate 1 by a wiring pattern 3. Spacers 5 may be
provided on the second substrate 2 corresponding to the restriction
regions, and the spacers 5 form restriction with the wiring pattern
in at least one direction parallel to the substrates. The first
substrate 1 may include a pixel region and the peripheral area
other than the pixel region.
[0028] According to an exemplary embodiment of the present
disclosure, the first substrate 1 may be an array substrate, and
the second substrate 2 may be a color film substrate.
[0029] According to an exemplary embodiment of the present
disclosure, the forming restriction in at least one direction
parallel to the substrates may include forming restriction in at
least two directions.
[0030] According to a further exemplary embodiment of the present
disclosure, the wiring pattern includes a wiring and/or a mark line
pattern, the wiring including at least one of a gate line lead
wire, a data line lead wire, a common electrode lead wire, an
electrostatic protection ring, and a repair line. The marking line
is, for example, a marking or alignment marking line in a
manufacturing process.
[0031] According to an exemplary embodiment of the present
disclosure, the at least one restriction region 4 may be
constituted by a gap between at least two parallel and/or
intersecting wires 3.
[0032] For example, the at least one restriction region 4 may be
formed by two parallel adjacent wires 3 and a wire 3 perpendicular
to the adjacent wires 3 so as to form restriction in both
directions toward the adjacent wires 3.
[0033] FIG. 3 schematically shows a restriction structure in this
embodiment. As shown in FIG. 3, the adjacent wire 31 and the wire
32 in the peripheral area of the array substrate 1 are connected to
the wire 33 through the via holes, respectively, and the space
between the wire 31 and the wire 32 forms the restriction region 4.
A spacer 5 is provided on the color film substrate 2 disposed
opposite to the array substrate 1, and the spacer 5 corresponds to
the position of the restriction region 4 on the array substrate 1
forming a restriction structure when the color film substrate 2 is
aligned with the array substrate 1. When the color film substrate 2
and the array substrate 1 are subjected to a lateral displacement
tendency due to an external force, the restriction structure may
restrict the displacement in both directions, i.e., the direction
from the spacer 5 toward the wire 31, and the direction from the
spacer 5 toward the wire 32.
[0034] As a further example, at least two restriction regions 4 are
formed by two parallel adjacent wires 3 and a wire 3 perpendicular
to the adjacent wires 3 so as to form restriction in four
directions toward the adjacent wires 3 and toward the perpendicular
wire 3.
[0035] FIG. 4 schematically shows the restriction structure in this
embodiment. As shown in FIG. 4, the spacer group of the spacers 51
and 52 and the restriction regions 41 and 42 formed by the wires
31, 32 and 33 constitute a restriction structure, producing
restriction for the displacement of the two substrates in the two
directions.
[0036] According to another exemplary embodiment of the present
disclosure, the at least one restriction region is formed by a bent
portion of a single wire 3.
[0037] FIG. 5 schematically shows the restriction structure in this
embodiment. As shown in FIG. 5, the restriction region 4 is formed
by bending a single wire 3 itself on the array substrate 1, and the
spacer 5 on the color film substrate 2 is provided in the
restriction region 4 formed by the bending, producing restriction
for the displacement in the two directions toward the bent
portions.
[0038] According to an exemplary embodiment of the present
disclosure, the wire 3 includes at least one peripheral wire of a
display panel.
[0039] According to an exemplary embodiment of the present
disclosure, the spacers 5 are provided in at least two different
restriction regions 4, the spacers and the different restriction
regions performing restriction in at least two different directions
parallel to the substrates.
[0040] According to a further exemplary embodiment of the present
disclosure, the angle between the two different directions is
90.degree. or 180.degree..
[0041] According to an exemplary embodiment of the present
disclosure, at least one spacer 5 is provided on the second
substrate at a position corresponding to the wire 3 in the
peripheral area of the first substrate. In this way, the at least
one spacer 5 may serve as a support.
[0042] According to an exemplary embodiment of the present
disclosure, at least a portion of the spacers in the spacer 5
differ in shape or size depending on different restriction regions.
In this way, different spacers can be adapted to restriction areas
of different shapes, so as to better play the required restriction
role. FIG. 6 schematically shows an example in which different
spacers correspond to different shapes of different restriction
regions. As shown, in the two restriction regions 43, 44
constituted by a plurality of wires 3, the two spacers 53, 54 have
different shapes and sizes so that the spacers 53, 54 are better
adapted to its corresponding restriction areas, so as to better
play the required restriction role.
[0043] In the above embodiments, the wire 3 may be an existing
peripheral wire in the array substrate 1, and the spacers 5 may be
existing spacers having a supporting function in the color film
substrate 2, and in this case, it is necessary to adjust the
positions of at least a portion of the existing spacers so as to be
located in the restriction region 4. The spacers 5 may also be
spacers provided apart from the existing spacers and dedicated to
play the restriction role. The spacers 5 may be one or more, and
the restriction regions 4 may also be one or more. In addition,
different spacers 5 in different restriction regions 4 may restrict
in different directions.
[0044] Another aspect of the present disclosure provides a display
device including a display panel according to any one of the
preceding embodiments.
[0045] It is to be understood that the above embodiments are merely
illustrative embodiments for the purpose of illustrating the
principles of the present disclosure and that the present
disclosure is not limited thereto. It will be apparent to those
skilled in the art that various changes and modifications can be
made therein without departing from the spirit and spirit of the
present disclosure, which are also intended to be within the scope
of the present disclosure. The scope of protection of the present
disclosure is limited only by the language representation of the
appended claims and equivalents thereof.
