Embodiment
Below in conjunction with Fig. 2 to Fig. 4 the method for making of touch-screen in the structure of touch panel display device of the present utility model and this touch panel display device is described.
Fig. 2 is the structural representation of a kind of better embodiment of the utility model touch panel display device, and this touch panel display device comprises the display 10 and the folded touch-screen 20 that is located at described display surface 12 sides of a tool display surface 12.Described touch-screen 20 is bonded in the surface of display surface 12 sides of described display 10 by frame glue 30.
See also Fig. 3 again, it is the side structure synoptic diagram of touch-screen 20 shown in Figure 2.Described touch-screen 20 comprises substrate 22, inductive layer 24, electrode layer 25, protective seam 28 and shielding layer 26.Described substrate 22 comprises the first surface (not indicating) and second surface (not indicating) that is oppositely arranged.Described inductive layer 24 is formed at the first surface of described substrate 22.Described electrode layer 25 is located between described inductive layer 24 and the described protective seam 28.Described shielding layer 26 is located at the second surface of described substrate 22.When described touch-screen 20 and described display 10 superimposed settings, the display surface 12 that the protective seam 28 of described touch-screen 20 closes on described display 10 is provided with.
In the present embodiment, described substrate 22 can adopt glass, polyethylene terephthalate (Polyethylene Terephthalate, PET), insulating material such as force-bearing plate.Force-bearing plate claims the PC plate again, be to be raw material with macromolecule engineering plastics polycarbonate (be called for short PC), a kind of high-quality sheet material that adopts coextrusion techniques (CO-EXTRUSION) to form, since its surface coverage one deck high concentration ultraviolet light absorber, except that the anti-ultraviolet characteristic of tool, also can keep weather-proof for a long time, colour-fast.
Described inductive layer 24 can be that (Indium Tin Oxide, ITO) conductive layer also can be other transparent conductive materials to indium tin oxide.Described inductive layer 24 is by forming in described substrate 22 first surface etchings.
Described electrode layer 25 be arranged at described inductive layer 24 surface perimeter and with its electric connection.Described electrode layer 25 comprises contact conductor, and this contact conductor can be metal or other conductive materials, can be chromium (Cr) as the metallic conduction material, molybdenum (Mo), aluminium (AL) or chromium, molybdenum and aluminium (Mo/Al/Mo) three-decker.Described electrode layer 25 can use sputtering way to form.
Described protective seam 28 is arranged at described inductive layer 24 and described electrode layer 25 outside surfaces, avoids damaging to protect described inductive layer 24 and described electrode layer 25.Described protective seam 28 is made by the material with light transmission, so that light can see through described protective seam 28 smoothly.In this implementation method, described protective seam 28 forms by technologies such as exposure, etchings, yet the technology of making of described protective seam 28 is not limited thereto.
In the present embodiment, described shielding layer 26 is a kind of metal oxide layers, as being the oxide formation of chromium (Cr).Described shielding layer 26 is the periphery that hollow frame type structure is located at the second surface of described substrate 22, and the middle position of promptly described substrate 22 second surfaces does not form described shielding layer 26.Described shielding layer 26 is black so that block the circuit of display surface 12 of described inductive layer 24 and described display 10 or pattern etc., so that the described touch-screen 20 clear viewing areas that define; Simultaneously, because described shielding layer 26 middle bodies are reserved the light transmission part, light can see through the sight line that described shielding layer 26 enters the observer smoothly, improves light transmission rate greatly.In addition, the oxide of described shielding layer 26 reason chromium (Cr) forms, so have advantages such as thin thickness, good uniformity, stable good and difficult second surface from described substrate 22 come off.
Fig. 3 is the manufacture craft process flow diagram of touch-screen among Fig. 2, and the manufacture craft flow process concrete steps of described touch-screen 20 are as follows:
Step S1: described substrate 22 is provided, and described substrate 22 comprises first surface and the second surface that is oppositely arranged;
Step S2: form described inductive layer 24 at described substrate 22 first surfaces, promptly form the induction electrode pattern at the first surface of described substrate 22 by sputter or vapour deposition mode;
Step S3: the method on described inductive layer 24 surfaces by sputter, etching forms described electrode layer 25, and described electrode layer 25 only is formed at the surface around the described inductive layer 24;
Step S4: make contact conductor (figure does not show) on described electrode layer 25, this contact conductor is distributed in described substrate 22 periphery surfaces, and this contact conductor is to be made by metal or other conductive materials;
Step S5: the method by coating, exposure and etching forms described protective seam 28 on described electrode layer 25 surfaces.Described protective seam 28 is an organic mixture, has characteristics such as printing opacity, insulation and anticorrosion;
Step S6: the method by sputter forms described shielding layer 26 at the second surface of described substrate 22.Specifically, earlier place a veil at described substrate 22 second surface middle positions, the vacuum gun that use is filled with oxygen is formed on the second surface of described substrate 22 with crome metal with sputtering way, and promptly the position forms the oxide layer of chromium around described substrate 22 second surfaces.That is, described shielding layer 26, and described substrate 22 second surface middle positions are owing to exist veil not form described shielding layer 26.
The protective seam 28 direct display surfaces 12 with described display 10 of touch-screen 20 described in the utility model touch panel display device are sticked; and the shielding layer 26 of described touch-screen 20 is positioned at the outermost of whole touch screen display device, so that the user operates by touching 20 pairs of described touch panel display devices of described touch-screen.
Be formed directly into the second surface of described substrate 22 in the utility model owing to the described shielding layer 26 of described touch-screen 20, be described shielding layer 26 and described inductive layer 24 shared described substrates 22, save a substrate than the situation that needs two substrates in the prior art.So described touch-screen 20 is little than needing two substrates to have thickness in the prior art, lightweight advantage.Simultaneously, the light beam that display 10 produces only needs can realize showing by single substrate, avoids passing multilager base plate and causes luminous energy to reduce, and improves light utilization efficiency greatly.
In the utility model touch panel display device, owing to adopt described touch-screen 20, the attenuation of described touch panel display device integral thickness, it is lighter that overall weight also becomes, bonding being more prone between the display surface 12 of described touch-screen 20 and described display 10.
The method for making of touch-screen 20 described in the utility model, because described shielding layer 26 is formed directly into the second surface of described substrate 22, be described shielding layer 26 and described inductive layer 24 shared described substrates 22, not only can save a substrate than the situation that needs two substrates in the prior art, and avoid two substrates is bonding by bonding coat, processing procedure is simple and cost is low.
Only be preferred case study on implementation of the present utility model below, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
