Abstract
The utility model discloses a capacitance screen assembly, which comprises a covering lens, a touch screen and a flexible circuit board, wherein the covering lens is arranged at the outmost layer, the touch screen is pasted on the inner side of the covering lens through double-side optical glue, the flexible circuit board is arranged on the touch screen and is used for transmitting electric signals, the edge of the inner side of the covering lens is provided with a printed layer, and an outer sleeve film with the smooth surface is arranged at the innermost layer of the covering lens. The capacitance screen assembly has the advantages that air bubbles caused at the pasting part of the covering lens and the touch screen can be avoided, in addition, the structure is simple, and the production is easy.
Description
Technical field
The utility model relates to a kind of capacitance plate assembly, relates in particular to a kind of capacitance plate assembly that can avoid producing bubble.
Background technology
Now, the capacitance plate assembly is applied in the various electric equipments more and more, under the prior art, as shown in Figure 1, the capacitance plate assembly generally comprises: be arranged on outermost covering lens 1, fit in the touch-screen 3 that covers lens 1 inboard and be arranged on the touch-screen 3 and be used for the flexible circuit board 31 of transmission of electric signals by two-sided optical cement 2, the edge that covers lens 1 inboard is provided with printed layers 11.Yet, because it is poor to produce section between printed layers 11 and the covering lens 1, therefore when covering lens 1 and touch-screen 3 applyings, be easy to generate bubble, thereby produce problems such as inner electrically bad connection, the deaeration technology of prior art generally will be more than 60 degree, 5 normal atmospheres depress and carry out, and can not thoroughly eliminate bubble.
The utility model content
In view of the defective that above-mentioned prior art exists, fundamental purpose of the present utility model is to propose a kind of capacitance plate assembly that can avoid producing bubble; Another purpose of the present utility model is the preparation method who proposes a kind of capacitance plate assembly.
The purpose of this utility model will be achieved by the following technical programs:
A kind of capacitance plate assembly, comprise and be arranged on outermost covering lens, fit in the touch-screen of described covering lens inboard and be arranged on the described touch-screen and be used for the flexible circuit board of transmission of electric signals by two-sided optical cement, the edge of described covering lens inboard is provided with printed layers, the most inboard outer embrane that is provided with a surface smoothing of described covering lens, described outer embrane covers described printed layers fully.
Further, described outer embrane covers the inside part of whole described covering lens.
Further, described pallial thickness is smaller or equal to 20 microns.
Further, described pallial material is any one in acryl series, epoxy series, polyurethane series and the alkene series plastics.
Further, described pallial material is UV hardening resin or thermmohardening type resin.
Following constipation closes the embodiment accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
Description of drawings
Fig. 1 is the structural representation of prior art capacitance plate assembly;
Fig. 2 is the structural representation of the utility model capacitance plate assembly.
Among the figure:
1 covers lens 11 printed layers 12 outer embranes
2 optics double faced adhesive tapes, 3 touch-screens, 31 flexible circuit board
Embodiment
As shown in Figure 1, the utility model capacitance plate assembly comprises and is arranged on outermost covering lens 1, fits in the touch-screen 3 that covers lens 1 inboard and be arranged on the touch-screen 3 and be used for the flexible circuit board 31 of transmission of electric signals by two-sided optical cement 2, the edge that covers lens 1 inboard is provided with printed layers 11, and the innermost layer that covers lens 1 is provided with the outer embrane 12 of a surface smoothing.
Preferably, outer embrane 12 covers the inside part of whole covering lens 1; Because the thickness of printed layers 11 is generally 12 microns, therefore, the thickness of the outer embrane 12 in the present embodiment is the 13-20 micron, thereby has guaranteed that the section difference between printed layers 11 and the covering lens 1 is thoroughly eliminated.At this moment, touch-screen 3 and the whole binding face that covers between the lens 1 can both keep smoothly, thereby can avoid producing bubble, and then just do not need to carry out complicated de-bubble technology.
The preparation method of the capacitance plate assembly in the present embodiment comprises the steps:
A) prepare printed layers 11 in the inboard of described covering lens;
B) with optics double faced adhesive tape 2 described outer embrane 12 is fitted in the inboard that covers lens 1, note the precision of applying, avoid producing bubble;
C) with optics double faced adhesive tape 2 touch-screen 3 is fitted in the inboard of outer embrane 12, note the precision of fitting, avoid producing bubble.
Printed layers 11 generally is used to increase the aesthetics of electrical equipment, and the printed layers 11 of different color can be set according to actual needs, as: black, yellow, blueness, redness, green, silvery white etc.Its preparation technology generally comprises following steps:
At first, the surface clean that will cover lens 1 with pure water is clean, because if exist foreign matter, surface to be easy to generate rough phenomenon; Then, on the position that covering lens 1 need, print the printing ink of required color; At last, carry out cure operations, it is that UV hardening furnace under the 800MJ makes it sclerosis that the UV hardening resin is used in energy, and the duration be 10-15 minute, thermosetting resin will use drying oven to make it sclerosis.After all process steps is finished check check whether obvious defects is arranged to the outward appearance that covers lens 1.
The utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
