Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
Fig. 1-Fig. 3 is please referred to, the naked eye 3D touch-control display module in the present invention includes the cover board from top to bottom set gradually
10, touch control layer 20, grating carrier 30, reflecting layer 40 and display component 50.
The preparation method of the naked eye 3D touch-control display module of the embodiment of the present invention, includes the following steps:
S01: reflecting layer 40 is arranged on the first side of grating carrier 30.
Specifically, reflecting layer 40 is metallic reflector.
S02: after reflecting layer 40 is arranged in the first side of grating carrier 30, touch control layer 20 is transferred to the of grating carrier 30
Two sides form barrier grating.
It should be understood that touch control layer 20 is arranged first on substrate 60.The step specifically: by point of nanometer conductive material
Dispersion liquid is coated on the inorganic rigid substrate 60 of surfacing, by the solvent in heat treatment removal dispersion liquid, thus inorganic
The side of rigid substrates 60 forms the conductive grid of nanometer conductive material, etches conductive grid, forms touch control electrode pattern.Nanometer
Conductive material dispersion liquid with a thickness of 1-2um.Touch control electrode pattern edge silk-screen silver paddle on 60 surface of substrate, toasts and etches
Edge-silver paddle lead is formed, that is, touch control layer 20 is made.
Secondly, being coated with the first glue-line 70 far from the side of substrate 60 in touch control layer 20, by photo solidification machine, carry out pre- solid
Change.The light transmittance of first glue-line 70 is greater than 90%, and cure shrinkage is less than 0.2%.The light precuring energy of first glue-line 70 is
2000~4000mj/c ㎡ can either be avoided solidifying due to the first glue-line 70 so insufficient and is difficult to consolidate touch control layer 20
It is fixed on grating carrier 30, also can be avoided due to the too high cure shrinkage for causing the first glue-line 70 of light precuring energy too
There is warpage greatly, and then improves the production yield of display module.
After 70 precuring of the first glue-line, second of side and grating carrier 30 by the first glue-line 70 far from touch control layer 20
Side fitting carries out final curing by photo solidification machine, forms barrier grating semi-finished product.Wherein touch control layer 20 and reflecting layer 40 are set up separately
On grating carrier 30.
The substrate 60 of barrier grating semi-finished product is removed, barrier grating is formed.Specifically, by substrate 60 from grating carrier
30, it is separated in the assembly of reflecting layer 40, touch control layer 20, the first glue-line 70 and substrate 60, realizes and touch control layer 20 is transferred to light
Second side of grid carrier 30 as one kind and form barrier grating.
S03: the reflecting layer 40 of barrier grating is bonded with display component 50, and reflecting layer 40 is set to grating carrier 30 and display
Between component 50.
Specifically, the reflecting layer 40 of barrier grating is bonded by the second glue-line 80 with display component 50, deaeration of pressurizeing.
S04: the barrier grating for being fitted with display component 50 is bonded with cover board 10, and cover board 10 is set to touch control layer 20 far from light
The side of grid carrier 30 as one kind.
Specifically, the barrier grating for being fitted with display component 50 is bonded by third glue-line 90 with cover board 10, that is, it is made
Naked eye 3D touch-control display module.
It should be understood that the second glue-line 80 and third glue-line 90 are optical adhesive layer.
The preparation method of naked eye 3D touch-control display module provided by the above embodiment is by individually making touch control layer 20
On 60 surface of substrate, and in coated on one side first glue-line 70 of the touch control layer 20 far from substrate 60, by the first glue-line 70 by touch-control
Layer 20 is transferred to grating carrier 30 close to the side of cover board 10, then separates substrate from said combination body, and being formed has touching
The barrier grating of function is controlled, then barrier grating is bonded with cover board and display component, realizes naked eye 3D touch display function.It is above-mentioned
Preparation method can be avoided since the material in reflecting layer 40 is generally soluble in acid solution, carry when in the grating for being equipped with reflecting layer 40
When making touch control layer 20 by acid etching process on body 30, reflecting layer 40 is easy to be etched, and causes naked eye 3D touch-control display module
The problem of scrapping.Thus, the preparation method of naked eye 3D touch-control display module provided in an embodiment of the present invention successfully solves simultaneously
