As shown in fig. 7, 8 and 9, fig. 7 is a back side view of the display panel 200 of fig. 2 after being bonded to the substrate 300, fig. 8 is a cross-sectional view B-B of fig. 7, and fig. 9 is a cross-sectional view C-C of fig. 7. The display panel 200 is bonded to the substrate 300 through the bonding layer 500, so that the gap 510 and the substrate 300 enclose an air-extracting channel 700, and the air-extracting channel 700 is communicated with a gap 810 formed between the display panel 200 and the substrate 300;
as shown in fig. 9, the display device further includes a blocking portion 830, and the blocking portion 830 is disposed at the opening of the pumping channel 700 and can close the pumping channel 700.
The adhesive layer 500 may be a double-sided adhesive tape or an adhesive layer, which is not specifically limited herein; the blocking portion 830 may be a curing adhesive, such as a UV adhesive, a sealing tape, or a valve, and is not limited in this respect.
After the display panel 200 and the substrate 300 are bonded, the gap 810 between the display panel 200 and the substrate 300 is pumped to a negative pressure state through the pumping channel 700, at this time, the display panel 200 can be bonded with the substrate 300 under the action of the atmospheric pressure, and after the gap 810 is pumped to the negative pressure state, the blocking portion 830 closes the pumping channel 700 to prevent external gas from entering the gap 810 from the pumping channel 700 to damage the negative pressure bonding between the display panel 200 and the substrate 300. By the negative pressure bonding between the display panel 200 and the substrate 300, the display device can eliminate the visual sense of separation during use, and solve the problem that the substrate 300 and the display panel 200 are easy to fog. Meanwhile, since the display panel 200 and the substrate 300 are attached together, a display newton ring caused by the cover plate bending inward and propping the display panel 200 can be avoided in the using process, so that the display effect of the display device can be greatly improved.
In addition, the air exhaust channel 700 penetrates through the adhesive layer 500 to communicate with the gap 810, so that the air exhaust channel 700 does not need to be arranged on the display panel 200 or the substrate 300, and the damage to the structure of the display panel 200 or the substrate 300 can be greatly reduced.
In some embodiments, as shown in fig. 8, the corner formed by the substrate 300 and the edge of the display panel 200 is provided with a sealing layer 820, and the sealing layer 820 is disposed around the display panel 200. By providing the sealing layer 820, the gap 810 can be better prevented from being filled with external air, so that the adhesion effect between the substrate 300 and the display panel 200 can be ensured.
Wherein, in order to ensure the smoothness of the pumping channel 700, the sealing layer 820 should avoid the channel opening of the pumping channel 700. The sealing layer 820 may be a cured adhesive layer, such as a UV adhesive layer, but is not limited thereto, and other sealing layers 820 capable of sealing between the edge of the display panel 200 and the substrate 300 may be used.
As shown in fig. 10, fig. 10 is a flowchart of a method for bonding a substrate 300 and a display panel 200 in a display device according to some embodiments of the present invention, where the method includes:
s1, as shown in fig. 7 and 8, bonding the peripheral edge of the display panel 200 to the substrate 300 through the adhesive layer 500;
wherein, S1 may include the steps of:
s11, as shown in fig. 4 and 5, an adhesive layer 500 is disposed at a peripheral edge of the display panel 200, and the adhesive layer 500 is disposed around the display region 210 of the display panel 200 and has notches 510 penetrating through inner and outer side surfaces of the adhesive layer 500.
As shown in fig. 5 and 6, when the adhesive layer 500 is a double-sided adhesive tape, the notch 510 may be formed by: the double-sided adhesive tapes are sequentially attached to four side edges of the display panel 200, as shown in fig. 6, one of the double-sided adhesive tapes m1 has a length smaller than the other three double-sided adhesive tapes, so that the gap 510 is formed between the end of the double-sided adhesive tape m1 and the end of the adjacent double-sided adhesive tape m2 after the attachment is completed.
Of course, in addition to the above, the notch 510 may be formed by: the double-sided adhesive tape is sequentially attached to four sides of the display panel 200, and the four double-sided adhesive tapes are connected end to form a rectangular shape, and then a part of material is removed from one double-sided adhesive tape to form the notch 510.
S12, as shown in fig. 7 and 9, the display panel 200 is bonded to the substrate 300 through the adhesive layer 500, such that the gap 510 and the substrate 300 enclose the pumping channel 700.
Of course, in addition to the steps described in S11 and S12, the pumping channel 700 may be provided in other ways, for example, a through hole may be formed in the substrate 300 before the display panel 200 is bonded to the substrate 300, and the through hole is the pumping channel 700.
S2, as shown in fig. 8, a sealing layer 820 is disposed at a corner formed by the edges of the substrate 300 and the display panel 200. Wherein the sealing layer 820 is disposed around the display panel 200.
By providing the sealing layer 820, the gap 810 can be better prevented from being filled with external air, so that the adhesion effect between the substrate 300 and the display panel 200 can be ensured.
S3, the gap 810 between the display panel 200 and the substrate 300 is evacuated by the air-extracting device, so that the display panel 200 and the substrate 300 are bonded.
As shown in fig. 6 and 9, the air-extracting device extracts the gap 810 to a negative pressure state through the air-extracting channel 700, so that the display panel 200 can be attached to the substrate 300 under the action of the external atmospheric pressure.
Between steps S1 and S2, the following steps may be further included: the air exhaust part is embedded in the air exhaust passage 700. Wherein the air extracting part can be an air extracting probe of an air extracting device. By pre-embedding the air exhaust component, the problem that the air exhaust component is difficult to put in due to the fact that the air exhaust channel 700 is blocked in the subsequent steps can be well solved.
After step S3, the following steps may be further included: the air extracting part is pulled out, the blocking part 830 is arranged at the passage opening of the air extracting channel 700 to close the air extracting channel 700, and the blocking part 830 can be conveniently closed to close the air extracting channel 700 by pulling out the air extracting part. By providing the blocking portion 830, it is avoided that the gas enters the gap 810 from the pumping channel 700 to affect the bonding effect between the display panel 200 and the substrate 300.
When the blocking portion 830 is a curing adhesive, before the air exhaust component of the air exhaust device is pulled out from the air exhaust channel 700, the curing adhesive is disposed at the channel of the air exhaust channel 700 in advance, so that after the air exhaust component is pulled out, the curing adhesive can timely block the air exhaust channel 700 and cure the blocking portion to form the curing adhesive.
In addition to the positional relationship between the blocking portion 830 and the sealing layer 820 shown in fig. 9, the sealing layer 820 is disposed at the corner formed by the edge of the substrate 300 and the display panel 200 after the air extracting member is embedded, and the blocking portion is formed after the air extracting member is extracted, so that only the blocking portion may exist at the air extracting passage 700.
The same or similar features in the embodiments of the method for bonding the substrate 300 and the display panel 200 as those in the embodiments of the display device may be referred to the description of the embodiments of the display device, and are not repeated herein.
In other embodiments of the present application, the display panel 2000 is a touch-sensitive liquid crystal display, that is, a touch sensor function is embedded in the liquid crystal display, so that the screen becomes thinner and lighter, which is called an cell touch-sensitive liquid crystal display, and is a touch-sensitive capacitive screen.
Fig. 11 is a schematic structural diagram of an acell touch-control liquid crystal display, and as shown in fig. 11, the touch-control layer is located inside the liquid crystal display.
When the incell touch-control liquid crystal display 2000 is attached to the substrate, similar to the above attaching method, the incell touch-control liquid crystal display 2000 is firstly placed on a special attaching jig platform, the adhesive layers 5000 are attached to four edges of the edge of the incell touch-control liquid crystal display 2000, and the adhesive layers 5000 are closed end to end and are similar to a square.
Then, the substrate 3000 cleaned by the cleaning machine is placed on the alignment jig, and after alignment is completed, the substrate 3000 and the cell touch liquid crystal screen 2000 are attached together.
In order to ensure that no gap exists between the substrate 3000 and the incell touch lcd 2000, and ensure the stability of the capacitance signal of the touch module, after the substrate 3000 and the incell touch lcd 2000 are completely attached, negative pressure treatment, i.e., vacuum pumping, needs to be performed between the substrate 3000 and the incell touch lcd 2000. A vacuum-pumping position, namely a notch, is reserved at one corner of the cell touch liquid crystal display 2000, and vacuum-pumping treatment is performed at the notch after the notch is attached. After vacuumizing, the middle part can reach the state of complete lamination under the effect of negative pressure, and zero-gap zero-medium between the lower substrate 3000 and the cell touch liquid crystal screen 2000 in the 0 lamination state is ensured, so that the zero lamination reaches the product state of full lamination.
In order to further ensure that no air, dust, water vapor or the like exists between the substrate 3000 and the incell touch-control liquid crystal display 2000, the periphery of the attached incell touch-control liquid crystal display 2000 is sealed. That is, the sealing layer 8200 is disposed on one side of the adhesive layer 5000, and the sealing layer 8200 is disposed at an edge position of the liquid crystal panel.
Fig. 12 shows a partial structure of the display panel bonded to the substrate. As shown in fig. 12, an adhesive layer 5000 is disposed between the substrate 3000 and the cell touch lcd 2000, and a sealing layer 8200 is disposed on one side of the adhesive layer 5000.
In the related art, a full-lamination mode is adopted for manufacturing a capacitive screen touch module, specifically, a touch layer and a substrate are firstly laminated together through a glue material, and the glue material covers the whole substrate plane. And the attached touch module is fully attached to the display panel. The manufacturing process needs to be laminated twice, the manufacturing process is complex, and the consumption of the rubber material is large. Because the two times of lamination are all coated with glue, if quality failure occurs, the possibility of repair is avoided.
Compared with the manufacturing method of the capacitive screen touch module in the related art, the method has the advantages that the cell touch liquid crystal screen is adopted in some embodiments, the touch layer is embedded into the liquid crystal screen, and then the zero-laminating scheme is adopted to realize the lamination of the substrate and the cell touch liquid crystal screen. The process only needs one-time bonding, the manufacturing process is simplified, the bonding layer only needs to be applied around, the whole surface does not need to be coated with glue, the using amount of the bonding layer is reduced, and the cost is reduced. And because the adhesive layer is only coated with glue on the peripheral edge, if abnormity occurs in the process of attaching or using, rework can be carried out.
In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
