10th, touch control layer 20, grating carrier 30, reflecting layer 40 and display module 50.
The preparation method of the bore hole 3D touch-control display modules of the embodiment of the present invention, comprises 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 set 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 set first on substrate 60.The step is specially：By point of nanometer conductive material
Dispersion liquid is coated on the inorganic rigid substrate 60 of surfacing, by being heat-treated the solvent removed in dispersion liquid, so as to inorganic
The side of rigid substrates 60 forms the conductive grid of nanometer conductive material, etches conductive grid, forms touch control electrode pattern.Nanometer
The thickness of conductive material dispersion liquid is 1-2um.Touch control electrode pattern edge silk-screen silver oar on the surface of substrate 60, toasts and etches
Edge-silver oar lead is formed, that is, touch control layer 20 is made.
Secondly, the first glue-line 70 is coated with side of the touch control layer 20 away from substrate 60, by photo solidification machine, carried out pre- solid
Change.The light transmittance of first glue-line 70 is more than 90%, and cure shrinkage is less than 0.2%.The light precuring energy of first glue-line 70 is
2000~4000mj/c ㎡, it can either so avoid being difficult to consolidate touch control layer 20 because the first glue-line 70 solidifies insufficient
It is fixed on grating carrier 30, can also avoids 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 improve the production yield of display module.
After the precuring of the first glue-line 70, by the second of side of first glue-line 70 away from touch control layer 20 and grating carrier 30
Side is bonded, and is carried out final curing by photo solidification machine, is formed barrier grating semi-finished product.Wherein touch control layer 20 and reflecting layer 40 sets up separately
On grating carrier 30.
The substrate 60 of barrier grating semi-finished product is removed, forms barrier grating.Specifically, by substrate 60 from grating carrier
30th, separated in the assembly of reflecting layer 40, touch control layer 20, the first glue-line 70 and substrate 60, realize and touch control layer 20 is transferred to light
Second side of grid carrier 30 as one kind and form barrier grating.
