All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In the embodiments of the present application, the azimuth or positional relationship indicated by the terms "upper", "lower", etc. are based on the azimuth or positional relationship shown in the drawings, and are merely for convenience of description and simplification of the description, and are not indicative or implying that the apparatus or element referred to must have a specific azimuth, be configured and operated in a specific azimuth, and thus should not be construed as limiting the present application.
The embodiment of the application provides a display device, which may be a mobile phone, a notebook computer, an Ultra Mobile Personal Computer (UMPC), a netbook, a Personal Digital Assistant (PDA), a wearable device, a virtual reality device, or other devices with a display panel, and the embodiment of the application is not limited thereto. For convenience of description, the display device is illustrated as a notebook computer.
The display device includes a housing and a display panel mounted on the housing.
The display panel is used for displaying static or dynamic images. The display panel can be an LCD display panel and comprises an array substrate and a color film substrate which are arranged in a stacked manner. The array substrate comprises a substrate, a pixel driving circuit arranged on the substrate, and binding terminals arranged on the substrate, wherein the binding terminals are electrically connected with the pixel driving circuit. The bonding terminals may be electrically connected to a flexible circuit board or other device through a bonding process. The substrate may be a glass substrate. The color film substrate comprises a substrate and an optical filter arranged on the substrate, and the substrate can be a glass substrate. Liquid crystal molecules and the like can be arranged between the array substrate and the color film substrate.
The housing may be used to mount or house other components of the display device in addition to the display panel. For example, when the display device is a notebook computer, the housing includes an upper shell and a lower shell that are pivotally connected, and after the upper shell and the lower shell are buckled, the housing includes an opposite upper shell B surface and an opposite lower shell C surface, and an opposite upper shell a surface and an opposite lower shell D surface. The display panel can be installed on the surface B of the upper shell, and the keyboard is arranged on the surface C of the lower shell. The lower shell can be also provided with a central processing unit, a main board, a hard disk, a memory, a battery and the like.
Wherein, the upper case for mounting the display panel may include a case and a rear case. The shell is used for fixing and protecting the display panel, and the rear shell is used for forming an A face. During assembly, the display panel can be firstly installed on the shell to form the display module, and then the display module is installed on the rear shell, so that the display panel can be assembled and disassembled by taking the display module as a unit, and the display panel is not easy to damage.
The display panel can be overlapped with the shell, and the overlap joint refers to that the display panel and the shell are overlapped and connected along the direction vertical to the light emitting surface, and the connecting surface of the display panel and the shell is an overlap joint surface. For example, a part of the structure of the housing is connected to a side of the display panel facing away from the light emitting surface, so that the display panel overlaps with the part of the structure of the housing. The overlapping area of the display panel and the shell is an overlapping area.
The display panel may include a plurality of edges including a first edge, and the first edge of the display panel may overlap the case, i.e., the overlapping region is located at the first edge of the display panel. The edge refers to an area formed by extending one edge of the display panel to the inside of the display panel for a certain distance, and does not refer to a side edge of the display panel.
Illustratively, the first edge is a lower edge of the display panel. In the display module, a driving circuit board of the display panel can be arranged below the lower edge of the display panel. In the practical application process, the display panel can be a rectangular display panel, and four edges of the display panel are all lapped with the shell, namely, the four edges of the display panel are all provided with lapping areas.
The shell can comprise a supporting wall, and the edge of the display panel can be lapped on the supporting wall, so that one side of the display panel, which is away from the light emitting surface, is jointed with the supporting wall. When the light-emitting surface side of the display panel is pressed, the support wall can support the display panel.
Fig. 1 is a sectional view of a portion of a display module, and fig. 2 is a top view of the display panel in fig. 1. As shown in fig. 1, the display module includes a display panel 10, a glue frame 23 and a supporting wall 21 disposed on the lower side of the display panel 10, wherein the edge of the display panel 10 facing away from the light-emitting surface is lapped on the supporting wall 21 through the glue frame 23, and the overlapping area of the display panel 10 and the supporting wall 21 is a lapping area 10a (the area within the dashed line frame in fig. 1). The display panel 10 is an LCD display panel, and includes an array substrate 11 and a color film substrate 12 that are stacked. The array substrate 11 located in the overlap region 10a is provided with a binding terminal 13, and the binding terminal 13 is used for binding with the driving chip and the flexible circuit board. In order to expose the binding terminals 13 for binding with the driving chip and the flexible circuit board, the color film substrate 12 in the overlap region 10a is partially or completely cut off in the related art. As shown in fig. 2, in the overlap region 10a, the edges of the array substrate 11 and the color film substrate 12 are not flush, and the second edge 12a of the color film substrate 12 is retracted a certain distance relative to the first edge 11a of the array substrate 11, so that a part of the area of the array substrate 11 is exposed to form a binding region, and the binding terminals 13 are disposed in the binding region.
In performing a strength test (e.g., a POGO test) on the display module, it is necessary to apply pressure to the edge of the display panel 10 in a direction perpendicular to the display panel 10. Since part or all of the color film substrate 12 in the overlap region 10a is cut away, only the array substrate 11 and the supporting wall 21 overlap in the part region 10a, but no color film substrate 12, the structural strength of the display panel 10 is reduced, and the display panel 10 is easily damaged.
Fig. 3 is a partial structural cross-sectional view of a display module according to an embodiment of the present application. As shown in fig. 3 to 7, the overlap region 100a in the embodiment of the present application includes a first region 120a, no color film substrate 120 is disposed in the first region 120a, and the first region 120a is configured to expose the bonding terminal 130. The overlap region 100a may include a plurality of first regions 120a, where the plurality of first regions 120a are arranged at intervals along the extending direction of the first edge, a second region 120b is disposed between two adjacent first regions 120a, and the second region 120b is provided with a color film substrate 120. That is, the color film substrate 120 in the first region 120a is cut, so that the bonding terminals 130 disposed in the first region 120a are exposed, thereby facilitating the bonding of the bonding terminals 130. The color film substrate 120 in the second area 120b is not cut and remains, so that the second area 120b includes two layers of structures of the array substrate 110 and the color film substrate 120, the area of the color film substrate 120 in the overlap area 100a is increased, the structural strength of the display panel 100 in the overlap area 100a is improved, and the display panel 100 is not easy to be damaged in the strength test process.
That is, along the extending direction of the first edge, at least a portion of the area adjacent to the bonding terminal 130 has the color filter substrate 120. The entire area of the color film substrate 120 is cut out, unlike the extension direction along the first edge in the related art. For example, in fig. 2, the edge of the array substrate 11 in the overlap region 10a is a first edge 11a, the edge of the color film substrate 12 is a second edge 12a, and the entire color film substrate 12 located between the first edge 11a and the second edge 12a is cut away.
The second region 120b may be disposed on one side of the first region 120a, or the second region 120b may be disposed on both sides of the first region 120a, which is not limited in this embodiment.
In practice, the color film substrate 120 may be provided with openings, where the openings are located in the overlap region 100a, and one of the openings is configured to expose at least a portion of the bonding terminal 130. The color film substrate 120 may be provided with a plurality of openings, and the plurality of openings are arranged at intervals along the extending direction of the first edge. The hollowed-out area formed by one opening is a first area 120a, and the area between two adjacent openings can be a second area 120b.
The edge of the array substrate 110 at the first edge is a first edge 111, and the edge of the color film substrate 120 at the first edge is a second edge 121. The array substrate 110 may be flush with the color film substrate 120 at the first edge, where flush refers to the projection of the first edge 111 and the second edge 121 on the light emitting surface. The overlapping of the first edge 111 and the second edge 121 increases the area of the color film substrate 120 in the overlap region 100a, that is, the area of the overlap region 100a including the double-layer structure of the array substrate 110 and the color film substrate 120 increases, which increases the structural strength of the overlap region 100a and reduces the damage probability of the display panel 100.
The second side 121 of the color film substrate 120 may be a continuous straight line segment, or may be a plurality of line segments that are spaced apart and collinear, which is not limited in the embodiment of the present application.
When the second edge 121 is a continuous straight line segment, the edge of the first region 120a near the first edge may be spaced apart from the second edge 121 of the color film substrate 120 by a certain distance. When the second side 121 of the color film substrate 120 is a plurality of spaced and collinear line segments, the first area 120a may partially overlap with the second side 121, so that a partial area of the second side 121 is cut.
In order to improve the structural strength of the display panel 100 in the overlap region 100a, the area of the color film substrate 120 in the overlap region 100a needs to be increased, so that the area of the first region 120a needs to be reduced as much as possible on the premise of exposing the bonding terminal 130 and meeting the bonding process requirement, that is, only the color film substrate 120 in the region corresponding to the bonding terminal 130 is cut, while the color film substrates 120 in other regions are not cut. For example, holes are formed in the color film substrate 120, so that the binding terminals 130 are exposed through the holes, and binding of the binding terminals 130 is achieved through the holes. At this time, the first region 120a is an open region.
Fig. 4 is a partial top view of a display panel according to an embodiment of the present application. As shown in fig. 4, a long hole is formed in the color film substrate 120, so that the binding terminal 130 is exposed through the long hole. At this time, the area corresponding to the elongated hole is a first area 120a, the left and right uncut areas of the first area 120a are a second area 120b, and the area between the elongated hole and the second side 121 is a third area 120c. Since the color film substrate 120 in the third region 120c is not cut, the area of the color film substrate 120 in the overlap region 100a is increased, and the structural strength of the display panel 100 is improved.
Wherein the distance between the first region 120a and the second edge 121, i.e. the distance between the opening and the second edge 121, is w. In the practical application process, w needs to be greater than or equal to the preset distance to meet the process requirement of opening the color film substrate 120. When w is too small, the color film substrate 120 in the third region 120c is easily narrowed, the structural strength is weak, and the color film substrate is easily damaged when being subjected to external force. The preset distance can be flexibly set according to the material of the substrate in the color film substrate 120 and the process conditions. For example, when the substrate of the color film substrate 120 is glass, the preset distance may be greater than or equal to 1mm.
When the second edge 121 of the color film substrate 120 is flush with the first edge 111 of the array substrate 110, the second edge 121 of the color film substrate 120 is retracted a certain distance from the first edge 111, and the w size is larger, i.e. the area of the third region 120c is increased, so that the structural strength of the display panel 100 is better.
Of course, the second edge 121 of the color film substrate 120 may also protrude from the first edge 111 of the array substrate 110, i.e. the first edge 111 of the array substrate 110 is retracted a certain distance relative to the second edge 121 of the color film substrate 120. Therefore, the size of w can be larger, the process requirement of opening the color film substrate 120 is met, and the risk of damage caused by too narrow width of the color film substrate 120 in the third region 120c is reduced.
When the color film substrate 120 protrudes a certain distance from the array substrate 110, a buffer layer may be disposed between the color film substrate 120 and the supporting wall 210 to support the color film substrate 120, so as to prevent the protruding portion of the color film substrate 120 from being damaged by external force.
When the size of w is too small, the area of the opening near the second edge 121 is weakened to prevent damage. The third region 120c may not be provided between the aperture and the second side 121. That is, the opening is in the shape of a notch, and the opening is open toward one side of the second side 121. At this time, the second side 121 of the color film substrate 120 is in a plurality of spaced and collinear line segments.
Fig. 5 is a partial top view of a display panel according to an embodiment of the present application. Illustratively, as shown in fig. 5, the opening cuts away a portion of the second side 121 of the color film substrate 120. At this time, the first region 120a partially overlaps the second edge 121 of the color film substrate 120.
The binding terminals are plural, and the plural binding terminals may include plural sets of terminal groups. The terminal group comprises a plurality of binding terminals, and the binding terminals are bound with the same electric element or flexible circuit board. The plurality of terminal groups may include a first terminal group 131 for binding with a driving chip and a second terminal group 132 for binding with a flexible circuit board. The first terminal group 131 and the second terminal group 132 may be arranged at intervals along the first edge extending direction. Illustratively, the second terminal group 132 is disposed between adjacent two of the first terminal groups 131.
The opening for exposing the first terminal group 131 may be elongated hole-like. Illustratively, the openings are elongated holes as shown in fig. 4.
In practical application, as shown in fig. 8, a frame glue (not shown in the figure) for connecting the color film substrate 120 and the array substrate 110 may be disposed between the color film substrate 120 and the array substrate 110, and the array substrate is further provided with a Vcom line 420, where the Vcom line 420 is located at one side of the frame glue facing the display panel 100. The distance w between the opening and the second edge 121 may be greater than or equal to the distance between the outer ring Vcom line 420 in the array substrate 110 and the outer edge of the frame glue, so as to facilitate binding of the driving chip 410 and the first terminal group 131.
The openings for exposing the second terminal set 132 may be in the shape of a notch. Illustratively, the openings are in the shape of a slit as shown in fig. 5.
When the opening for exposing the second terminal set 132 is in a shape of a long hole, the flexible circuit board bound with the second terminal set 132 needs to be bent in a direction away from the array substrate 110 after the binding is completed, so as to extend out of the long hole. Due to the narrow space of the strip holes, bending of the flexible circuit board is difficult, and the flexible circuit board may be damaged due to bending. When the opening for exposing the second terminal group 132 is in a notch shape, the flexible circuit board bound with the second terminal group 132 can directly extend along the direction parallel to the light emitting surface of the display panel 100 after the binding is completed, without bending.
Of course, in the practical application process, the first terminal set 131 and the second terminal set 132 may be exposed through the elongated openings, or may be exposed through the opening-shaped openings. Alternatively, the first terminal group 131 is exposed through the opening-like opening, and the second terminal group 132 is exposed through the elongated opening. The embodiments of the present application are not limited in this regard.
When the first terminal group 131 is bound to the driving chip, a custom press head binding or a laser binding may be used. In the binding process, when the customized press head contacts with the wall of the hole, or when the gluing needle coated with the conductive adhesive contacts with the wall of the hole, the color film substrate 120 is pressed to generate Mura defect. Therefore, the size of the opening can be appropriately increased.
Illustratively, after binding is completed, the distance between the driver chip and the two sidewalls of the opening may be greater than or equal to 0.6mm in a direction perpendicular to the first edge; the distance between the driver chip and the two sidewalls of the opening may be greater than or equal to 1mm in a direction parallel to the first edge. Of course, in the practical application process, the adjustment may be performed according to the size of the custom-made pressure head and the size of the glue spreading needle, which is not limited in the embodiment of the present application.
In order to prevent stress concentration of the color film substrate 120 at the openings, the sidewalls of the openings may be smoothly transitioned. Illustratively, as shown in fig. 4, the openings are generally rectangular holes with rounded corners at each of the four corners. Of course, the shape of the opening is not limited thereto, and may be a waist-shaped hole, an elliptical hole, or the like, as long as the respective inner walls of the opening are smoothly transitioned to reduce stress concentration.
The number of the first regions 120a in the overlap region 100a may be one or more.
When the overlap region 100a includes only one first region 120a, i.e., only one opening is formed in the overlap region 100a, all the terminal groups are exposed through only one opening. The second region 120b may be located on one side of the first region 120a along the first edge, or the second region 120b may be located on opposite sides of the first region 120a along the first edge. At this time, the color film substrate 120 corresponding to the area between two adjacent terminal groups is also cut away, so that the internal space of the opening is larger, and the binding operation of the first terminal group 131 and the second terminal group 132 is facilitated. And the technological difficulty of opening holes is reduced.
When the overlap region 100a includes a plurality of first regions 120a, the plurality of first regions 120a may be arranged at intervals along the extending direction of the first edge, and a second region 120b is disposed between two adjacent first regions 120 a. This increases the area of the second region 120b, i.e., the panel of the color film substrate 120, thereby increasing the structural strength of the display panel 100.
When a plurality of first regions 120a are included in the overlap region 100a, one first region 120a may be configured to expose a group of terminal groups. Because the terminal groups are arranged in groups and the terminal groups are arranged at intervals, the second area 120b can be arranged between two adjacent first areas 120a, the area of the color film substrate 120 is increased, the strength of the display panel 100 is improved, and the display panel 100 is not easy to break in the strength test process.
Fig. 6 is a top view of a display panel according to an embodiment of the present application. As shown in fig. 6, the second terminal set 132 is located between two adjacent first terminal sets 131, and the first terminal sets 131 correspond to the elongated openings, and the second terminal sets 132 correspond to the opening openings.
When the overlap region 100a includes a plurality of first regions 120a, one first region 120a is configured to expose adjacent sets of terminals. Illustratively, one first region 120a is configured to reveal two adjacent sets of terminals. Of course, in the practical application process, one first area 120a may be configured to expose three, four, five, etc. adjacent terminal groups, and the number of terminal groups exposed by one first area 120a is not limited in this embodiment.
When a first area 120a exposes multiple terminal groups at the same time, although the color film substrate 120 corresponding to the area between two adjacent terminal groups is cut away, the area of the color film substrate 120 is reduced. However, since one first area 120a simultaneously exposes multiple groups of terminal groups, the number of the first areas 120a is reduced, that is, the number of openings is reduced, and the probability of the color film substrate 120 between two adjacent openings being damaged due to the smaller size is reduced under the condition that the number of the terminal groups is identical.
With continued reference to fig. 1, the display module in fig. 1 includes a back plate disposed on a side of the display panel 10 facing away from the light emitting surface, for protecting the display panel 10. The back plate is usually a stamped metal plate structure, and the supporting wall 21 is a part of the back plate and is formed by bending the edge of the back plate towards the display panel 10, so that the supporting wall 21 is in a cantilever structure as a whole. When the strength test is performed on the display module, pressure is applied to one side of the light emitting surface of the display panel 10 along the direction perpendicular to the display panel 10, and the pressure is transferred to the supporting wall 21, so that the supporting wall 21 with the cantilever structure is easily bent towards the direction away from the display panel 10, thereby losing the support to the display panel 10 and further causing the display panel 10 to break in the overlapping area 10 a. Therefore, in order to prevent chipping, it is necessary to strengthen the structural strength of the support wall 21, preventing the support wall 21 from being deformed by bending during the strength test.
With continued reference to fig. 3, in the embodiment of the present application, the housing includes a back plate, the back plate includes a body 220 and a supporting wall 210, the body 220 and the display panel 100 are disposed at intervals, the backlight module 300 of the display panel 100 is located between the body 220 and the display panel 100, the supporting wall 210 is connected to an edge of the body 220, the overlap region 100a is overlapped on the supporting wall 210, and the supporting wall 210 includes a first wall 211 and a second wall 212 which are sequentially stacked along a direction towards the display panel 100.
For the supporting wall 21 is only composed of one layer of metal plate, the supporting wall 210 in the embodiment of the application comprises the first wall 211 and the second wall 212 which are stacked, so that the rigidity of the supporting wall 210 is increased, the supporting wall 210 is not easy to bend and deform, the supporting effect of the supporting wall 210 on the display panel 100 is better, and the display panel 100 is prevented from being broken in the strength test process. And, the supporting wall 210 is composed of the first wall 211 and the second wall 212, and the thickness of the back plate is reduced, so that the display module is lighter and lighter than the prior art.
Illustratively, the first wall 211 and the second wall 212 are each an aluminum alloy material. The first wall 211 and the second wall 212 are made of aluminum alloy, and compared with stainless steel, the aluminum alloy wall meets the strength requirement, and is light in weight and low in cost.
The back plate may be a sheet metal structure of a unitary structure, and the first wall 211 and the second wall 212 are formed by bending a sheet metal. Illustratively, the first wall 211 and the second wall 212 are double-sided structures, formed by stamping.
The support wall 210 is generally along the connection between the support wall 210 and the back plate body 220, i.e. the bending between the support wall 210 and the body 220, when bending and deforming. In order to prevent the support wall 210 from being bent and deformed, the first wall 211 may cover the bending portion, so that at least two layers of structures are included at the bending portion, thereby improving the structural rigidity of the back plate at the bending portion.
Illustratively, a connection wall 230 is connected between the support wall 210 and the body 220, the connection wall 230 is connected with the body 220 by a first fold 200a, and the connection wall 230 is connected with the support wall 210 by a second fold 200b, so that the support wall 210, the connection wall 230 and the body 220 form a U-shaped structure.
Illustratively, as shown in FIG. 3, the first wall 211 may extend to encase the first fold 200a.
Fig. 7 is a partial structural cross-sectional view of a display module according to an embodiment of the present application. Illustratively, as shown in fig. 7, the first wall 211 may extend to cover both the second bend 200b and the first bend 200a.
The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present application, and the changes and substitutions are intended to be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
