Refer to shown in Fig. 2, it is the schematic diagram that this utility model difference implements the touch control display apparatus 1a of aspect.
The touch control display apparatus 1 of touch control display apparatus 1a and Figure 1A primary difference is that; the touch control electrode layer 123 of touch control display apparatus 1a is arranged on protective substrate 121 on the first surface 1211 of display floater 11; anti-blu-ray layer 122 is then arranged on display floater 11 on the upper surface 111 of protective substrate 121; more specifically; touch control electrode layer 123 is the first surface 1211 being formed directly into protective substrate 121 by photolithographic processes, and anti-blu-ray layer 122 is to be formed directly into the upper surface 111 of display floater 11 by evaporation or sputter process.It addition, be additionally provided with adhesion coating 124 between touch control electrode layer 123 and anti-blu-ray layer 122, the protective substrate 121 with touch control electrode layer 123 is allowed to be fitted in the display floater 11 with anti-blu-ray layer 122 by adhesion coating 124 further.In another embodiment; formed after the first surface 1211 of protective substrate 121 at touch control electrode layer 123; processing procedure will not damage touch control electrode layer 123; anti-blu-ray layer 122 can pass through evaporation or sputter process is formed at touch control electrode layer 123 on the surface of display floater 11; and also set up adhesion coating 124 between anti-blu-ray layer 122 and display floater 11, allow the protective substrate 121 with touch control electrode layer 123 and anti-blu-ray layer 122 be fitted in the upper surface 111 of display floater 11 further by adhesion coating 124.Thus structure, anti-blu-ray layer 122 is to be arranged on the upper surface 111 of display floater 11 by adhesion coating 124.
It addition, other technical characteristic of touch control display apparatus 1a is referred to touch control display apparatus 1, do not repeat them here.
What be supplemented with is; touch control electrode layer 123 is except the touch electrode structure of the such as single conductive layer shown in Figure 1A and Fig. 2; also can design is the touch electrode structure of bilayer conductive layer; and the touch-control structure of multilager base plate of arranging in pairs or groups; such as double; two glass (Glass-Glass; GG), two thin walls (Glass-Film-Film; GFF) etc.; allowing the different laminated position that anti-blu-ray layer 122 can be arranged between protective substrate 121 from display floater 11 according to the convenience of the difference of touch-control structure and processing procedure, this utility model is also not intended to.
Refer to shown in Fig. 3, it is the light spectrum diagram by anti-blu-ray layer of the present utility model.
Be can be seen that by Fig. 3, when light-emitting component (such as LED) emitted light of display floater 11 is by anti-blu-ray layer 122, wavelength of light in the penetrance of 380nm～427nm less than 1%, and the light that wavelength is less than 435nm is also almost filtered out, hence it is evident that shortwave blue light and ultraviolet (UV) can effectively be intercepted；It addition, when light has the touch control display apparatus of anti-blu-ray layer 122 by this utility model, wavelength of light is in the average penetration rate of 445nm～700nm more than 90%, and therefore, the color shown by display floater 11 can't distortion.
Hold; touch control display apparatus of the present utility model be provided with between protective substrate and display floater most to the first material layer and the anti-blu-ray layer that stacks of the second material layer; the refractive index of the first material layer is more than the refractive index of the second material layer; and the thickness of the first material layer is between 20 nm and 50 nm, and the thickness of the second material layer is between 20 nm and 70 nm.Penetrate and the characteristic such as polarization through the reflection of anti-blu-ray layer, thoroughly (folding), can reach the wavelength light less than 430nm is low penetration rate, but the light of wavelength 445nm～700nm is the effect of high penetration, therefore, touch control display apparatus can effectively intercept shortwave blue light and ultraviolet, can ensure that display color is undistorted simultaneously.
In sum; in touch control display apparatus of the present utility model with contact panel; be provided with between protective substrate and display floater most to the first material layer and the anti-blu-ray layer that stacks of the second material layer; the refractive index of the first material layer is more than the refractive index of the second material layer; and the thickness of the first material layer is between 20 nm and 50 nm, and the thickness of the second material layer is between 20 nm and 70 nm.Make touch control display apparatus of the present utility model and contact panel can effectively intercept shortwave blue light and the ultraviolet that display screen sends, can ensure that display color is undistorted simultaneously.
The above is only illustrative, rather than restrictive.Any without departing from spirit and scope of the present utility model, and its equivalent modifications carried out or change are gone back, all should include in the appended claims.
