Description
Technical field
The present invention relates to the technical field of capacitive touch screen, a kind of standardization application structure based on capacitive touch screen specifically, particularly its mechanical connecting structure, present technique is applicable to the various capacitance touching control mobile phones of current main flow trend.
Background technology
Increasingly mature along with capacitive touch screen technology in mobile device market constantly weeded out the old and bring forth the new in the handset structure design, emerged in large numbers the structural design schemes that launch around capacitive touch screen in a large number.How to break through on the one hand the restriction bottleneck of capacitive touch screen to structural design, the restriction at utmost capacitive touch screen designed the mobile phone complete machine structure to the greatest extent drops to minimum becomes the tackling key problem difficult problem that each family of mobile phone industry must study carefully.On the other hand, capacitive touch screen is difficult to improve, manufacture the relatively high each side factor of threshold because of its complex process, yield, cause its manufacturing cost and commercial value always high, at increasingly competitive current mobile phone market, how the cost of capacitive touch screen is dropped to the minimum direction that each manufacturer chases and makes great efforts that also becomes to the impact of complete machine cost.Simultaneously, increase the selection range of LENS, the standardization that increases complete machine structure intensity, promotion Sensor reduces the die sinking expense also becomes focus just day by day.
At present existing mobile phone development trend is the big screen intelligent mobile phone, and from structure, capacitive touch screen collocation large scale display screen is scheme full-fledged under this trend, and can occupy the empery status within the several years.Capacitive touch screen technology both domestic and external roughly is divided into two kinds structure, and a kind of is that capacitive touch screen (containing Sensor and LENS) is fitted with the LCM display screen as a whole; Another kind be by capacitance plate Sensor be integrated in the glass of LCM or be integrated on LENS.The former is current main flow trend, and the latter is because of the each side technical bottleneck, but there is no at present ripe volume production technology.The shortcoming of the first kind of way that main flow is used is:
1, Sensor(sensor module) and the LENS(eyeglass) bind together, the two any one adjustment is arranged, just need to newly open a CTP(capacitive touch screen in fact), be unfavorable for flexible selection collocation and the standardization of material.
2, be subject to the impact of the factors such as Sensor manufacturing process, die sinking expense, binding yield, the CTP cost occupy always high-leveled and difficult under.
3, the appearance of CTP in complete machine, easily be subject to external impacts, in actual use, impaired unavoidably because Sensor and LENS are that full laminating is inseparable, once LENS by impact grinding or damage, whole CTP scraps immediately, must whole replacing.Thereby cause the maintenance tear the machine difficulty open and rehabilitation cost high.
4, the making of LENS will be considered laminating and the complete machine ID outward appearance of Sensor simultaneously, aspect selection and moulding, all can be subject to more restriction.
Summary of the invention
The object of the present invention is to provide a kind of standardization application structure based on capacitive touch screen, be based on the handset structure design optimization scheme of capacitive touch control techniques, capacitive touch screen (CTP) and display screen (other show module LCM or OLED etc.) are carried out to splitting and reorganizing, separate with LENS by the Sensor by CTP, Sensor part and LCM are fitted entirely.The LENS part is determined according to casing.Between Sensor and LCM, can use the OCA optical cement entirely to fit, also can use frame glue that periphery is fitted, recommendation OCA laminating, can avoid water ripples, reduce to greatest extent and light loss and colour cast, and can be better dustproof, overcome the shortcoming and defect existed in the prior art.
To achieve these goals, technical scheme of the present invention is: a kind of standardization application structure based on capacitive touch screen, it comprises sensor module, it is characterized in that: described sensor module and Liquid Crystal Module laminating, the upper surface of sensor module is provided with eyeglass, sensor module and eyeglass are separated, and the lower surface of sensor module is provided with Liquid Crystal Module, and the lower surface of Liquid Crystal Module is provided with printed circuit board.
The invention discloses a kind of standardization application structure based on capacitive touch screen, be based on the handset structure design optimization scheme of capacitive touch control techniques, by the subversiveness optimization to the traditional design scheme, make it compared with prior art, there is following advantage and good effect: the Sensor standardized and popularized that 1, is beneficial to CTP.Sensor and LCM are fit together, make Sensor become standard component with the specification of LCM, the unique corresponding Sensor specification of the LCM of a size, do not need the repetition die sinking to revise Sensor and meet the collocation from different LCM, and can save the loaded down with trivial details debugging much brought because of the difference collocation yet in later stage complete machine software debugging; 2, make complete machine that larger Costdown space can be arranged.Aspect Sensor and LCM attaching process, can utilize traditional inclined to one side subsides technology to realize, also can utilize OCA mono-class glue attaching process to realize, technology is skillful, and yield is promoted, the cost relative reduce; Sensor, once standardization, without die sinking making repeatedly, makes die cost and greatly reduces; The selection range of LENS is more extensive, without the tempered glass of selecting hardness, amount of deflection extra-high-speed, reduces material cost; 3, can increase complete machine structure intensity, reduce maintenance cost, strengthen the after-sales service operability.Because compare traditional CT P, after Sensor and LENS divide out, after LENS is subject to external force deformation, can, more directly by the stressed Sensor layer that is delivered to, not cause CTP to lose efficacy.Thereby strengthened complete machine intensity, greatly reduced the impaired probability of Sensor.Damage even LENS is subject to excessive external impacts, only need to change cheap LENS and get final product, do not need to change whole CTP, thereby reduce after-sales service cost and operability; 4, widen the selection range of LENS, increase the rich of ID moulding, improve the yield of CTP assembling.The moulding of LENS no longer is subject to the structural limitations of Sensor, can carry out moulding according to complete machine ID outward appearance, comprises that more popular 2.5D radian moulding at present all can easily realize.Selection is PC or the PMMA of optional cheapness, flexible enough height when cost is low.
