Embodiment
When at present PMMA/PC composite plate is as the panel of self-tolerant touch-screen, because the rigidity of PMMA/PC composite plate is low, easily distortion, for more than 4 cun and 4 cun touch-screens, can't use at present, the utility model provides a kind of mobile terminal with large scale electric capacity touch-screen, by the spacing design between type selecting, CTP structural design, the design of mobile terminal casing structure, the design of LCD liquid crystal module, LCD display and the CTP of PMMA/PC composite plate, IC type selecting etc., make PMMA/PC composite plate successful Application on large scale self-tolerant touch-screen.
For making the purpose of this utility model, technical scheme and effect clearer, clear and definite, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, it is the part-structure schematic diagram that the utlity model has mobile terminal one preferred embodiment of large scale electric capacity touch-screen.As shown in Figure 1, the mobile terminal with large scale electric capacity touch-screen of the present utility model is the smart mobile phone with four cun of above capacitance touch screens, it comprises fore shell 10, back cover 20, and from fore shell 10 toward back cover 20 directions successively stacked CTP screen 30, LCD display 40, mainboard assembly 50, battery 60 and battery cover 70.In the present embodiment, described CTP screen 30 adopts PMMA/PC composite panel, on described fore shell 10, be provided with supporting construction, the both sides of the edge of described CTP screen 30 are fixed in described supporting construction, supporting construction is used for supporting described CTP screen 30, avoid CTP screen when pressing, there is larger distortion, this supporting construction also makes CTP screen 30 and LCD display 40 interval preset distances, while preventing CTP screen 30 by compressive strain, be expressed to LCD display 40, wherein, described preset distance is 0.4mm(millimeter) more than, thereby while effectively preventing that CTP screen 30 is pressed distortion, be expressed to LCD display 40, avoiding CTP screen 30 to press makes LCD display 40 occur water ripples, and mobile terminal static pressure, fall the unfavorable conditions such as LCD splits.
In the present embodiment, the thickness of the panel of described CTP screen 30 is preferably 1mm, and ITO Film(nesa coating) the width of supporting construction of both sides can be designed into maximum, guarantee that CTP screen 30 and fore shell 10 are bonding smooth reliable.The utility model adopts the supporting construction of widening, and guarantees that there is good support the both sides of CTP screen 30, avoids CTP screen 30 distortion when pressing larger.
During concrete enforcement, described supporting construction has multiple implementation, one preferred embodiment is steel disc 801, as shown in Figure 1, described supporting construction is the steel disc 801 of bending, and this steel disc 801 is two, described steel disc 801 can be bent into 90 degree, in one partial insertion fore shell 10, it is 30 parallel that another part of steel disc 801 and CTP shield, and described CTP screen 30 is fixed on another part of described steel disc 801.
In the present embodiment, the thickness of described LCD display is 0.5mm, guarantee after CTP screen 30 is by compressive strain, even if ITO Film Sensor(ITO thin film sensor) touch LCD display 40, also can guarantee has larger interval between LCD display 40 and ITO Film Sensor, make its distance L CD liquid crystal panel have certain distance, reduce LCD display 40 and CTP is shielded to the impact of 30 performances.
As shown in Figure 2, described supporting construction is the support level 802 of the broadening of one-body molded setting on fore shell 10 in another preferred embodiment of the present utility model, and the both sides of the edge of described CTP screen 30 are fixed on described support level 802.It should be noted that described support level 802 is for widening structure, the wide 3-5mm of width that should structure division than 10 pairs of traditional fore shells, guarantees enough well to support and hold CTP screen 30, avoids 30 distortion of CTP screen larger.
It is soft that the CTP forming because of PMMA/PC composite panel shields 30 materials, presses yieldingly, can cause LCD display 40 to show water ripples and occur static pressure, occur LCD display 40 bad phenomenon such as break while falling.In the present embodiment, the bottom surface of described support level 802 is than the high 0.05-0.15mm of the end face of LCD display 40, user operation is pressed CTP and is shielded 30 o'clock, can reduce LCD display 40 stressed, thereby improves water ripples and static pressure, fall the LCD display 40 bad generation such as break.
In the present embodiment, between described support level 802 and CTP screen 30, be provided with resilient coating 803, described resilient coating 803 is for foam glue-line and its thickness are 0.35-0.5mm, makes spacing between CTP screen 30 and LCD display 40 more than 0.4mm, avoids CTP to shield 30 interference that are subject to LCD display 40.
Preferably, the bottom surface of described support level 802 is 0.1mm to the distance of LCD display 40 end faces, and the thickness of described resilient coating is 0.3mm, and making the spacing between CTP screen 30 and LCD display 40 is 0.4mm, thereby take into account smart mobile phone ultra-thin in, can not affect the performance of CTP screen 30.
During concrete enforcement, it is Te sa 62948 foams that described resilient coating adopts model, and it has good sealing property, can dustproof and waterproof, absorption of noise; And this foam also has good resiliency, can possess certain deformation recovery capability, and absorb vibration and anti-impact force strong.
Because the present embodiment is only the different of supporting construction from the difference of above-described embodiment, the present embodiment is only described in detail supporting construction, and other structure as: the selection of LCD display 40, mainboard assembly 50, battery 60 and battery cover 70, structure etc., be not described further.
Further in embodiment, the utility model also improves the selecting of control chip of CTP screen 30, the utility model is preferably the control chip of supporting subregion triangle pattern, if model is the chip of FT6306 and MSG2138A, it is compared with other self-tolerant chips, has good antijamming capability.
In sum, the utility model adopts PMMA/PC composite panel, and on described fore shell, be provided with for supporting the supporting construction of described CTP screen, when assembling, the both sides of the edge of CTP screen are fixed in described supporting construction, and make CTP screen and LCD display interval preset distance, while preventing CTP screen by compressive strain, in LCD display, there is water ripples and static pressure, occur that the LCD display bad phenomenon such as break occurs while falling.And PMMA/PC composite panel compares with face glass, its cost is lower, and processing technology is simple, can not break, use safelyr, after using supporting construction of the present utility model, be adapted at using on large scale and mobile terminal of touch screen more than large scale.In addition, the utility model also, because the cost of material is low, processing technology is simple, the process-cycle is short etc., has promoted the market competitiveness greatly.
Be understandable that; for those of ordinary skills; can be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, and all these changes or replacement all should belong to the protection range of the appended claim of the utility model.
