Panel etc., is not limited thereto.Optical cement (optical clear adhesive, OCA) 120 is disposed on touch panel 110
Between display module 130, to sticking touch control panel 110 and display module 130.
Touch panel 110 includes transparent substrate 111, and transparent substrate 111 has the first side 111a relative to each other and the
Two side 111b.Metal mesh compartment 112 is set to the first side 111a of transparent substrate 111, and protective layer 114 is also disposed on transparent substrate
111 the first side 111a simultaneously covers metal mesh compartment 112.On the other hand, metal mesh compartment 113 is set to transparent substrate 111
The second side 111b, protective layer 115 are also disposed on the second side 111b of transparent substrate 111 and cover metal mesh compartment 113.Metal mesh
Compartment 112,113 can be electrically connected to a sensing circuit (not being painted) and form capacitance, outside touch control display apparatus 100
When user touches touch panel 110, this capacitance changes, and external sensing circuit then identifies use according to the variation of capacitance
The specific location of person's touch control operation.
Transparent substrate 111 can be rigid substrates or flexible base plate.In some embodiments, rigid substrates include glass,
Glass fibre or duroplasts, flexible base plate include polyethylene (PE), polyethylene terephthalate (PET), triacetate fiber
(TAC) or combinations thereof.In some embodiments, the thickness of transparent substrate 111 is 50~125 microns.Metal mesh compartment 112,113
Material be copper, silver or combinations thereof.In some embodiments, the thickness of metal mesh compartment 112,113 is 0.8~1.2 micron.Shape
The the first side 111a (the second side 111b) for being included in transparent substrate 111 at the step of metal mesh compartment 112 (113) forms metal
Layer, the method for forming metal layer include physical vaporous deposition or chemical vapour deposition technique.Next micro-photographing process, pattern are penetrated
Change above-mentioned metal layer to form metal mesh compartment 112 (113), this patterned method includes dry ecthing method or wet etch method.
The material of protective layer 114,115 may include any appropriate transparent insulating layer.
Due to having opaque structure, this black-matrix layer such as black-matrix layer may be with gold in display module 130
Belong to clathrum 112,113 and forms interference fringe (Moire pattern).In this embodiment, touch panel 110 or optical cement
120 have diffusing structure so that the mist degree (haze) of touch panel 110 or touch control display apparatus 100 is more than or equal to 5%, thereby
Above-mentioned interference fringe can be mitigated.It is worth noting that, interference fringe can not be inhibited if mist degree is too small, if mist degree is too big
Display effect can be influenced, therefore in some embodiments, the mist degree of above-mentioned generation can be between 5% to 20%.
For example, Fig. 2 is the sectional view that touch panel is painted according to an embodiment.Fig. 2 is please referred to, in the implementation of Fig. 2
In example, above-mentioned diffusing structure is multiple transparent particles (bead) 201, these transparent particles 201 are respectively formed in protective layer
114, among 115, the refractive index of transparent particles 201 is different from the refractive index of protective layer 114,115.Thus, work as light 210
When (or 211) directive transparent particles 201, the light 210 (or 211) for having part is scattered.Through these transparent particles of adjustment
201 size or concentration, can form 5% to 20% mist degree, and in some embodiments, the diameter of transparent particles 201 is to be situated between
Between 5 microns to 10 microns.In some embodiments, the forming method of transparent particles 201 may include：First by transparent particles
201 are added in the materials of protective layer 114 (or 115), later again by this material be coated on transparent substrate the first side 111a (or
The second side 111b) on.It is noted that the description of above-mentioned " transparent particles 201 are respectively formed among protective layer 114,115 "
Be formed on the surface of protective layer 114,115 including transparent particles 201, all be formed among protective layer 114,115 or
It is only partially formed among protective layer 114,115.
Fig. 3 is the sectional view that touch control display apparatus is painted according to an embodiment.Fig. 3 is please referred to, in the fig. 3 embodiment,
Above-mentioned diffusing structure is also multiple transparent particles 301, but these transparent particles 301 are provided in optical cement 120, transparent
The refractive index of particle 301 is different from the refractive index of optical cement 120.Thus, when 311 directive transparent particles 301 of light, meeting
There is the light 311 of part to be scattered, thereby forms 5% to 20% mist degree.Similarly, in some embodiments, transparent particles
301 diameter is between 5 microns to 10 microns.The forming method of transparent particles 301 may include：First by transparent particles 301
It is added into optical cement 120, optical cement 120 is coated on the surface of touch panel 110 or display module 130 again later, then
Touch panel 110 is bonded with display module 130.
Fig. 4 is the diagrammatic cross-section that concaveconvex structure on protective layer is painted according to an embodiment.Fig. 1 and Fig. 4 are please referred to, in order to
For the sake of simplification, protective layer 114 is only depicted in Fig. 4.In general, the roughness of body surface is got over hour, reflected light line
It is more；On the contrary, if when the roughness of body surface is bigger, the light of scattering is more.In this embodiment, it is through increase
The roughness on 114 surface of protective layer thereby forms 5% or more mist degree.Specifically, above-mentioned diffusing structure is protective layer
114 relative to the concaveconvex structure 401 on the surface of transparent substrate 111, and the forming method of this concaveconvex structure 401 is including the use of idler wheel
(roller) irregular groove indentation shape is extruded on the surface of protective layer 114, then resolidification is molded.Thus,
When light this concaveconvex structure 401 of directive, the light for having part is scattered, through adjustment concaveconvex structure 401 degree of roughness,
5% to 20% mist degree can be formed.In some embodiments, concaveconvex structure 401 can also be formed in protective layer 115 relative to
On the surface of transparent substrate 111.
