Description
Technical field
The utility model relates to the electronic product module technical field, is specifically related to a kind of ultra-thin capacitance type touch control screen.
Background technology
Capacitance type touch control screen is the significant components of electronic products such as smart mobile phone, e-book, notebook computer, its essence is and utilizes the induction by current of human body that screen is controlled.When the metal level of finger touch capacitance type touch control screen,, form coupling capacitance between finger and the capacitance touching control screen surfaces because there is electric field in human body; Electric capacity is direct conductor for high-frequency current; So finger is inhaled moving less current from contact point, this small electric flow point does not flow out the electrode from four jiaos of touch screens, and the electric current of these four electrodes of flowing through is directly proportional with the distance of pointing four jiaos; Controller draws touch point position through the accurate Calculation to these four current ratios.At present, capacitance type touch control screen is generally one or four layers of compound glass screen, comprises substrate layer, patterned layer, glue-line, display screen and is bundled in IC and the FPC assembly on the substrate layer.Substrate layer is mainly protected patterned layer, also is the demand of good looking appearance simultaneously.Glue-line mainly is to fit together substrate layer and patterned layer.Patterned layer is main function element, is on glass baseplate, to have plated the ITO pattern, and the branch of double-side pattern and single face pattern is generally arranged.The main effect of IC and FPC assembly is to calculate touch point also to repay to the mainboard processor.But the substrate layer of conventional condenser touch screen and ITO pattern base material are toughened glass panel; The own wt of toughened glass panel and thickness cause touch screen totally more thick and heavy; Be unfavorable for making light touch screen, in addition, because the substrate layer and the ITO pattern base material processing yield that adopt toughened glass panel to make are low; Make that the quality of touch screen is unstable, cost is high.
Summary of the invention
The utility model technical matters to be solved provides the ultra-thin capacitance type touch control screen of little, the in light weight and low cost of manufacture of a kind of thickness.
For solving the problems of the technologies described above; The utility model adopts following technical scheme to realize: a kind of ultra-thin capacitance type touch control screen; Comprise substrate layer, glue-line, patterned layer, display screen and be bundled in IC and the FPC assembly on the substrate layer; Patterned layer comprises substrate sheets and is arranged on the ITO pattern on the substrate sheets, and said substrate sheets is a film sheet, and said ITO pattern single face is plated on the film sheet and forms ITO pattern film sheet.
Said substrate layer is the acryl panel.
Above-mentioned ITO is the nano indium tin metal oxide, and the ITO pattern is a transparent conductive patterns.
During enforcement; The film that etch process capable of using will be coated with whole ITO is made into the ITO film sheet that has specific ITO figure; The individual layer ITO film can form a complete ITO touch control unit; And, overcome the different influences of acryl panel to the touch-control effect with the tempered glass specific inductive capacity through debugging to drive IC, combine specific I TO figure to be provided with again and solve of the interference of demonstration module touch control unit.
For solving the not wear-resisting problem of acryl panel, the inventor finds, makes case-hardened acryl panel through continuous casting process, can better promote the wearing quality of acryl panel.
Compared with prior art, the beneficial effect of the utility model is: the patterned layer of the utility model comprises substrate sheets and is arranged on the ITO pattern on the substrate sheets that substrate sheets is PET film or film sheet; ITO pattern single face is arranged on the PET film or ITO pattern single face is plated in formation ITO pattern film sheet on the film sheet; Substrate layer adopts the acryl panel simultaneously, adopts toughened glass panel to compare with tradition, reduces touch screen thickness, weight reduction greatly; Simultaneously because substrate sheets is a film sheet; Can adopt ripe printing etch process will make ITO pattern film sheet, the volume production yield is more easy to control, effectively reduces the manufacturing cost of touch screen.
Description of drawings
Fig. 1 is the utility model embodiment cross-sectional structure synoptic diagram.
Embodiment
Below will combine accompanying drawing and embodiment that the utility model is explained in further detail for the ease of it will be appreciated by those skilled in the art that.
As shown in Figure 1; A kind of ultra-thin capacitance type touch control screen; Comprise substrate layer 1, glue-line 2, patterned layer 3, display screen 4 and be bundled in IC and the FPC assembly 5 on the substrate layer; Patterned layer comprises substrate sheets 32 and is arranged on the ITO pattern 31 on the substrate sheets, and substrate sheets is a film sheet, and ITO pattern single face is plated in and forms ITO pattern film sheet on the film sheet.In the present embodiment, substrate layer is the acryl panel.
During enforcement; The film that etch process capable of using will be coated with whole ITO is made into the ITO film sheet that has specific ITO figure; The individual layer ITO film can form a complete ITO touch control unit; And, overcome the different influences of acryl panel to the touch-control effect with the tempered glass specific inductive capacity through debugging to drive IC, combine specific I TO figure to be provided with again and solve of the interference of demonstration module touch control unit.
For solving the not wear-resisting problem of acryl panel, the inventor finds, makes case-hardened acryl panel through continuous casting process, can better promote the wearing quality of acryl panel.
The patterned layer of the utility model comprises substrate sheets and is arranged on the ITO pattern on the substrate sheets; Substrate sheets is a film sheet, and ITO pattern single face is plated in and forms ITO pattern film sheet on the film sheet, and substrate layer adopts the acryl panel simultaneously; Adopt toughened glass panel to compare with tradition; Reduce touch screen thickness, weight reduction greatly,, can adopt ripe printing etch process will make ITO pattern film sheet simultaneously because substrate sheets is a film sheet; The volume production yield is more easy to control, effectively reduces the manufacturing cost of touch screen.
When acryl panel and ITO film sheet were fitted through glue-line, because of adhesion improves, the bubble fraction defective was lower, can effectively promote the attractive in appearance of touch screen.
Face glass has frangible characteristics; And the conventional condenser touch screen has two tempered glass, and it is bigger to fall the broken probability in back, Comparatively speaking; Present embodiment adopts the combination of acryl panel and film sheet then to promote toughness of products greatly; Even if under damaged situation, can as glass, not disperse yet and flash, the product safety in utilization promotes.
The foregoing description is the preferred version that the utility model is realized; And indefiniteness is exhaustive; The utility model can also have other variations under same idea; Need to prove that do not breaking away under the utility model design prerequisite, any conspicuous replacement and subtle change are all within the protection domain of the utility model.
