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.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
To further explain the technical means and effects of the present invention adopted to achieve the intended purpose, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.
Fig. 1 is a bottom view of a cover plate assembly 10 according to a first embodiment of the present invention. As shown in fig. 1, the cover plate assembly 10 includes a cover plate 11, a light shielding layer 12, and a support layer 13. The cover plate 11 defines a light-transmitting area 111 and a light-shielding area 112 located at the periphery of the light-transmitting area 111. The light-shielding layer 12 is located in the light-shielding region 112 and on a surface of the cover plate 11. The support layer 13 is located in the light-shielding region 112 and on the surface of the light-shielding layer 12 away from the cover plate 11. Wherein the cover plate 11 is transparent and the support layer 13 is transparent.
In one embodiment, the light-shielding layer 12 is a light-shielding ink. The shading ink can be a layer or a plurality of layers arranged in a ladder shape.
In one embodiment, the cover plate 11 is made of glass, such as soda glass, aluminosilicate glass, and alkali-free glass. In other embodiments, the cover plate 11 may be made of transparent plastic, acrylic, or any other material with a certain transmittance and capable of protecting the structure attached thereto.
In an embodiment, the material of the supporting layer 13 may include at least one of an ultraviolet light curing adhesive, an acrylic adhesive, and an acrylic adhesive.
Fig. 2 is a partial cross-sectional view of a touch display device 100 using the cover plate assembly 10 shown in fig. 1. As shown in fig. 2, the display device 100 includes a cover assembly 10, a light-curing adhesive layer 40, a touch display panel 20, and a flexible circuit board 30. The transparent area 111 corresponds to an area of the touch display device 100 for displaying a frame, and the light shielding area 112 corresponds to an area of a frame of the touch display device 100 for shielding the flexible circuit board 30 and other wires in the light shielding area 112.
The touch display panel 20 is located on the side of the cover assembly 10 where the light shielding layer 12 is disposed. The light-curing adhesive layer 40 is located between the cover plate assembly 10 and the touch display panel 20 to bond the cover plate assembly 10 and the touch display panel 20. The flexible circuit board 30 is bent and extended from a side of the touch display panel 20 close to the cover assembly 10 to a side of the touch display panel 20 away from the cover assembly 10. Wherein, the light-cured glue layer 40 is transparent. In one embodiment, the light-curable adhesive layer 40 is, for example, an ocr (optical Clear resin) optical adhesive.
The light-curing glue layer 40 partially covers the light-shielding layer 12 but does not cover the support layer 13. The height of the support layer 13 is not less than the height of the photo-curing glue layer 40 along the thickness direction of the display device 100, so that the projection of the flexible circuit board 30 and the projection of the glue layer do not overlap in the direction perpendicular to the thickness direction of the display device 100.
In one embodiment, the attaching step of the touch display panel 20 and the cover assembly 10 is as follows: pre-curing the photo-curing adhesive, and then attaching the cover plate assembly 10 to the touch display panel 20 through the pre-cured optical adhesive; after the bonding, the cover plate 11 is cured by ultraviolet irradiation on the side away from the touch display panel 20; then, performing side curing on the side surface of the touch display panel 20 (the direction of the arrow in fig. 2 is the direction of the ultraviolet irradiation); and then, carrying out primary curing in one step to completely cure the light curing glue in the coating area.
In the research process, the inventor of the present application finds that in the structure of the existing display device, the curing rate is insufficient in some areas of the cover plate, so that the yellow spots appear on the picture displayed by the touch display panel. The inventor researches that the curing rate of some areas of the cover plate is insufficient, mainly because the surface of the flexible circuit board can shield ultraviolet light which enters the light curing adhesive from the side surface after being bent.
As shown in fig. 2, in an embodiment of the invention, the cover plate assembly 10 is provided with a supporting layer 13, and after the touch display panel 20 and the cover plate assembly 10 are attached to each other, the bending deformation region of the flexible circuit board 30 abuts against the supporting layer 13, so that the flexible circuit board 30 does not raise to block ultraviolet light irradiated to the side surface of the photo-curing adhesive layer 40, and further the photo-curing adhesive layer 40 has a uniform photo-curing rate in the coating region thereof, and each region can satisfy that the curing rate is more than 95%.
In one embodiment, the supporting layer 13 has a transmittance of greater than 80% for light having a wavelength of 365nm to 420 nm. That is, the supporting layer 13 has a high transmittance to the ultraviolet light of 365nm to 420nm, so that the light-cured adhesive layer 40 has a better curing effect.
In an embodiment, the height of the supporting layer 13 is greater than or equal to the thickness of the light-curing adhesive layer 40, and the length and width of the supporting layer 13 covers the bending deformation region of the flexible circuit board 30, so that the bending region of the flexible circuit board 30 does not block the ultraviolet light irradiated from the side surface to the light-curing adhesive layer 40. The bending deformation region refers to a region where the flexible printed circuit board 30 is raised upward to shield the ultraviolet light irradiated from the side surface to the light-curing adhesive layer 40. In some embodiments, the height of the support layer 13 is 0.2mm or greater. The width of the support layer 13 (i.e., the width of the support layer 13 in the direction D1 in fig. 3 or 4) is 2mm to 5 mm. In some embodiments, the width of the supporting layer 13 is the width of the bending deformation region of the flexible circuit board 30.
In one embodiment, as shown in fig. 1, the support layer 13 is a continuous, integral layer. The support layer 13 is in a rectangular strip shape, and partially covers the light-shielding layer 12.
In another embodiment, as shown in fig. 3, the supporting layer 13 includes a plurality of supporting portions 131 arranged at intervals. The direction from the light-shielding region 112 to the light-transmitting region 111 is defined as the width direction D1 of the support layer, and the direction perpendicular to the width direction D1 of the support layer is defined as the length direction D2 of the support layer. The plurality of supporting portions 131 are provided at intervals along the longitudinal direction D2 of the supporting layer. Assuming that the length of the support layer 13 is L and the number of the support parts 131 is n (n is an integer of 2 or more), defining the length of each support part 131 projected on the cover plate 11 in the longitudinal direction D2 of the support layer as Wn, (W1+ W2+ … + Wn)/L x 100% is less than or equal to 30%, to obtain higher ultraviolet transmittance.
In fig. 3, each support 131 is a circle in projection on the cover plate 11, and Wn is the diameter of the circle. By disposing the plurality of support portions 131 at intervals along the length direction D2 of the support layer, part of the ultraviolet light irradiated from the side of the display device 100 can be directly irradiated to the photocurable layer without being blocked by the support layer 13, and thus, the curing effect of the photocurable layer is further improved.
In still another embodiment, as shown in fig. 4, the supporting layer 13 includes a plurality of supporting portions 131 arranged at intervals, a projection of each supporting portion 131 on the cover plate 11 is a rectangular bar shape, Wn is a width of the rectangle, (W1+ W2+ … + Wn)/L x 100% ≦ 30%, so as to obtain higher ultraviolet transmittance.
As shown in fig. 5, the plurality of supporting portions 131 are disposed at intervals on the surface of the light shielding layer 12 away from the cover plate 11. The adjacent support portions 131 have a gap therebetween. Thus, part of the ultraviolet light enters the light curing layer after entering the supporting portion 131, and part of the ultraviolet light is directly irradiated to the light curing layer from the gap without being shielded by the supporting portion 131, so that the curing effect of the light curing layer is further improved.
In other embodiments, the support portion 131 is not limited to the shape shown in fig. 3 and 4, and may have other shapes. For example, each support 131 may be a prism. In addition, the size of each support portion 131 may be different.
Referring to fig. 2 again, the touch display panel 20 includes a color filter substrate 21, an array substrate 22 disposed opposite to the color filter substrate 21, a liquid crystal layer (not shown) sandwiched between the color filter substrate 21 and the array substrate 22, a backlight module 23 disposed on a side of the array substrate 22 away from the color filter substrate 21, a first polarizer 24 disposed between the color filter substrate 21 and the light-curing adhesive layer 40, and a second polarizer 25 disposed between the array substrate 22 and the backlight module 23. The foam adhesive 50 is disposed between the backlight module 23 and the array substrate 22 to bond the two and play a role of buffering.
In fig. 2, the color filter substrate 21 has a protrusion area 211 extending beyond the first polarizer 24. The flexible circuit board 30 is bound to the protruding region 211 and bent to extend to a side of the backlight module 23 away from the cover plate assembly 10. In fig. 2, the flexible printed circuit 30 is bonded to the surface of the color filter substrate 21 close to the cover assembly 10. The surface of the flexible circuit board 30 bound to the protruding region 211 is defined as a first surface 31, and the surface opposite to the first surface 31 is defined as a second surface 32. Because the supporting layer 13 is disposed in the cover assembly 10, after the flexible circuit board 30 is bent, the height of the second surface 32 of the flexible circuit board 30 does not exceed the height of the first polarizer 24. That is, the flexible printed circuit 30 does not block the ultraviolet light incident from the side surface to the photo-curing adhesive layer 40 after being bent.
In one embodiment, the touch display panel 20 is an in-cell touch display panel 20. That is, the touch display panel 20 has both touch and display functions. The array substrate 22 is provided with a thin film transistor array layer (not shown) and a touch sensing layer (not shown). The flexible circuit board 30 is used for electrically connecting the touch sensing layer to a system motherboard (not shown) through a connector 60, so as to implement a touch function.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
