Referring to Fig. 1, is the touch display unit 10 in an embodiment, and comprise touch-screen 100 and display module 200, display module 200 is arranged at the side of touch-screen 100.
Touch-screen 100 comprises the nesa coating 110, protection panel 120 and the anti-dazzling film 130 that are cascading.The reverse side 112 that nesa coating 110 comprises front 111 and arranges back on front 111; protection panel 120 is arranged at the front 111 of nesa coating 110 by the 3rd glue-line 150; anti-dazzling film 130 comprises the anti-dazzle photosphere 131 that is cascading and the first base material 132, first base material 132 is arranged at the surface of protection panel 120 back on nesa coating 110.Display module 200 is arranged at the side of nesa coating 110 back on protection panel 120.
Nesa coating 110 can be the structure comprising basic unit and one deck conductive layer, or nesa coating 110 can be the structure comprising basic unit and two conductive layers.The material forming conductive layer can be ITO, wire netting, Nano Silver, Graphene or carbon nano-tube etc., the material of base material can be COP (Cyclo-olefinpolymer, cyclic olefin polymer), PET (polyethyleneterephthalate, polyethylene terephthalate) or glass.
Protection panel 120 can be the face glass of strengthening; also can be there is high permeability and the organic plastics panel of anti-scratch or organic plastics composite plate; such as PMMA (PolymethylMethacrylate; polymethylmethacrylate), PC (Polycarbonate, polycarbonate) etc.
See also Fig. 2, anti-dazzling film 130 comprises anti-dazzle photosphere 131 and the first base material 132, and anti-dazzle photosphere 131 comprises anti-dazzle particle.Anti-dazzle photosphere 131 is by the size of anti-dazzle particle and the composition of anti-dazzle particle to reach different mist degrees, and mist degree scope can selectivity adjustment between 2% ~ 28%, thus can present strong and weak different anti-glare effects and display imaging.
Anti-dazzle photosphere 131 is mainly formed by the mode of magnetron sputtering, vacuum evaporation or coating process anti-dazzle particle of arranging on the first base material 132, light produces diffuse reflection effect by anti-dazzle particle, reduce light to the direct irradiation of the eyes of beholder, play anti-dazzle effect.First base material 132 can be TAC (TriacetylCellulose, Triafol T) base material.
Specific in present embodiment, also comprise at least one first anti-reflection layer 133.That is, the quantity of the first anti-reflection layer 133 can be one or more layers.First anti-reflection layer 133 is arranged at the surface of anti-dazzle photosphere 131 back on the first base material 132, and the first anti-reflection layer 133 effectively can reduce the reflectivity of visible light wave range.The specular reflectance of the first anti-reflection layer 133 can control below 1%.First anti-reflection layer 133 can be formed by magnetron sputtering, vacuum evaporation or coating process mode.
Refer to Fig. 3, there is certain phase differential with the reflected light through the first anti-reflection layer 133 in the reflected light of the first base material 132, thus forms film interference phenomenon, causes two kinds of reflected light to be cancelled out each other to a certain extent, reaches the effect reducing reflectivity.Can, by the constituent of adjustment first anti-reflection layer 133 and the number of plies, its specular reflectance be made to reach 0.2%.
Specific in present embodiment, also comprise stain-proofing layer 134.Stain-proofing layer 134 is arranged at the surface of the first anti-reflection layer 133 back on anti-dazzle photosphere 131.Stain-proofing layer 134 exposes for preventing the first anti-reflection layer 133, avoids the first anti-reflection layer 133 by dust or other contaminating impurity.
Specific in present embodiment, also comprise the first glue-line 135, first glue-line 135 and be arranged between the first base material 132 and protection panel 120, for the first base material 132 being fitted in protection panel 120.Particularly, the first glue-line 135 can be Optical transparent adhesive, and Optical transparent adhesive is a kind of solid-state pressure sensitive adhesive, there is very high transmitance and lower water-intake rate, have very high optical property, its optical transmittance can reach more than 92%, and its principal ingredient is esters of acrylic acid.See also Fig. 4, specific in present embodiment, also comprise anti-reflection film 140, anti-reflection film 140 makes video picture more clear for generation of antireflective effect.Anti-reflection film 140 comprises the reverse side 112 that the second base material 141 of being cascading and the second anti-reflection layer 142, second base material 141 are arranged at nesa coating 110.That is, anti-reflection film 140 is between nesa coating 110 and display module 200.Second base material 141 can be TAC (TriacetylCellulose, Triafol T) base material.
As electromagnetic light wave in the process propagated, on the interphase of different medium, there is due to the difference of boundary condition different refractive indexes, when air (refractive index is n1), the second anti-reflection layer 142 (refractive index be n), the refractive index of the second base material 141 (refractive index is n2) is different.
By the second anti-reflection layer 142 on the second base material 141 plated surface, utilize the film interference principle of light that reflected light is weakened, as electromagnetic light wave in communication process, on the interphase of different medium, due to the difference of boundary condition, change the distribution of its energy, the energy distribution of the reflection and transmission of light there occurs change, and reflected energy reduces, and transmission potential increases, therefore the light source transmitance that showing module 200 provides increases, and video picture is more bright, clear.Display module 200 after anti-reflection has the optical transmittance of more than 96%.
Specific in present embodiment, between the second base material 141 and the reverse side 112 of nesa coating 110, be also provided with the second glue-line 143, for the second base material 141 is fitted in nesa coating 110.Particularly, the second glue-line 143 can be Optical transparent adhesive, and Optical transparent adhesive is a kind of solid-state pressure sensitive adhesive, there is very high transmitance and lower water-intake rate, have very high optical property, its optical transmittance can reach more than 92%, and its principal ingredient is esters of acrylic acid.
Specific in present embodiment, between protection panel 120 and nesa coating 110, be provided with the 3rd glue-line 150, for protection panel 120 and nesa coating 110 being fitted.Particularly, the 3rd glue-line 150 can be Optical transparent adhesive, and Optical transparent adhesive is a kind of solid-state pressure sensitive adhesive, there is very high transmitance and lower water-intake rate, have very high optical property, its optical transmittance can reach more than 92%, and its principal ingredient is esters of acrylic acid.
Display module 200 can be liquid crystal display mode group 200, and can be such as TFT liquid crystal display module 200, also can be IPS liquid crystal display module 200 or OLED display.
Above-mentioned touch display unit 10 and touch-screen 100 thereof at least have the following advantages:
