Specific embodiment
In order to keep the purpose of this utility model, technical solution and advantage clearer, with reference to the accompanying drawing and it is embodied
The utility model is described in detail in example.
Hereinafter, the specific embodiment that the utility model display module 100 will be introduced in conjunction with Fig. 1 to Fig. 4.The display mould
Group 100 includes the first functional layer 1 and the second functional layer 2 and the solid-state for bonding first functional layer 1 and the second functional layer 2
The thickness of optical adhesive layer 3, the solid state optics glue-line 3 is gradually reduced from intermediate to two sides.
In the application preferred embodiment, the thickness of the solid state optics glue-line 3 is along its length from intermediate to two
Side reduces, and the solid state optics glue-line 3 is gradually opposite from centre to two sides along its length in the upper and lower surface of thickness direction
Extend, so that shown solid state optics glue-line 3, during pasting, middle section first connects with the first functional layer 1 or the second functional layer 2
Touching, then successively extend to two sides and contact, and the bubble that will likely be generated successively discharges.In this application, the solid-state light
It is in smooth arc-shaped surface structure that glue-line 3 is learned in the upper and lower surface of thickness direction along its length, also can be regarded as the solid state optics glue
Layer 3 looks over substantially along its thickness direction in olive shape structure.In other embodiments, the thickness of the solid state optics glue-line 3
Degree also can also can be regarded as the solid state optics glue-line 3 and look over greatly along its thickness direction for from centre to two linear reductions
Cause assumes diamond in shape structure.
Due in display component, the too thick easy display effect for influencing touch-control display component of solid state optics glue, conversely, then
It is easy to cause the first functional layer 1 and being bonded for the second functional layer 2 insecure.Therefore, in the application preferred embodiment, institute
Stating the thickness difference range between the middle position and marginal position of solid state optics glue-line 3 is 25 μm~250 μm, the solid state optics
The light transmittance of glue-line 3 is not less than 99%.
Compared with liquid optical cement, the peeling force of solid state optics glue is larger, and the thickness of solid state optics glue is uniform, liquid
The cambial thickness of optical cement is easy to appear non-uniform phenomenon, also, solid state optics glue also has that there is no excessive glue phenomenons, cost
It is lower and fitting efficiency it is higher the advantages that, this but also the display module with solid state optics glue-line 3 with lower cost,
Higher fitting efficiency and preferable properties of product.
In this application, the solid state optics glue-line 3 can be OCA glue-line.OCA(OpticallyClearAdhesive)
Glue is also referred to as Optical transparent adhesive, with excellent clarity, high light transmittance, high adhesion, high-weatherability, water resistance, high temperature resistant,
Uvioresistant, for a long time use will not generate yellow or xanthochromia, removing and rotten good characteristic.In this embodiment, institute
It states solid state optics glue-line 3 and does not paste and include substrate when use and be sticked respectively in the heavy release film of the substrate two sides and light release
Film, in the application preferred embodiment, the removing rate range of the heavy release film is 20~30g/inch, described light release
The removing rate range of film is 3~7g/inch.In the present embodiment, weight release film and light release film have protective effect, when described solid
When state optical adhesive layer 3 will be bonded with the first functional layer 1 with the second functional layer 2 respectively, then will weight release film and light release film
It peels off.
In conjunction with removing rate of the solid state optics glue-line 3 in the application preferred embodiment and middle position and margin location
Thickness difference range between setting, such solid state optics glue-line 3 used by the display module can not only guarantee preferably aobvious
Show effect, also there is stronger peeling force, ensure that the bonding fastness between the first functional layer 1 and the second functional layer 2.
In this application, the solid state optics glue-line 3 is also possible to layer of silica gel.Silica gel absorption performance is high, thermal stability is good,
Chemical property stabilization and mechanical strength with higher.Therefore, both materials of the solid state optics glue-line 3 are very suitable to
For being pasted to touch-control film layer, polarisation film layer or display base plate.
The forming method of shown display module 100 is additionally provided in the application, the forming method includes: step S1:
The side of first functional layer 1 bonds solid state optics glue-line 3, and in this step, first functional layer 1 first contacts the solid-state light
Learn 3 middle section of glue-line, then to two sides successively extends contact to the both sides of the edge of solid state optics glue-line 3 also with the first functional layer 1
Bonding is close, so that it is guaranteed that not having between first functional layer 1 and the binding face of the solid state optics glue-line 3 being bonded to each other
Air enters, i.e., bubble-free generates;Step S2: the second function is sticked in the side that the first functional layer 1 is bonded with solid state optics glue-line 3
Ergosphere 2, in this step, second functional layer 2 first contact 3 middle section of solid state optics glue-line, then successively to two sides
Extend contact also to bond closely with the second functional layer 2 to the both sides of the edge of solid state optics glue-line 3, so that it is guaranteed that second function
There is no air entrance between layer 2 and the binding face of the solid state optics glue-line 3 being bonded to each other, i.e. bubble-free generates, thus institute
