Description
Technical field
The utility model relates to capacitance touch screen, particularly relates to a kind of capacitance touch screen with independent touch key-press.
Background technology
Along with the development of mobile phone industry, relative to touch panel being arranged on original method that liquid crystal panel uses, by research increasing prevalence integrated with liquid crystal panel for touch panel function.The integration of touch panel and liquid crystal panel comprises " In-cell " method and " On-cell " two kinds of methods.In-cell refers to the method be embedded into by touch panel function in liquid crystal pixel.On-cell refers to the method be embedded into by touch panel function between colored filter substrate and Polarizer.And Oncell and the Incell market share of a new generation will be increased in future for 2 years fast.
To show solution different from the touch of original external hanging type, and due to On-cell and In-cell structural limitations, induction pattern can not extend according to customer requirement as the touch-screen of external hanging type.For the project having independent touch key-press, way more common at present first key legend is made on FPC, then FPC is pasted on the cover board.As you know, the size of electric capacity and it have certain relation through the specific inductive capacity of medium, if FPC sticky be on the cover board have bubble, or the not enough button FPC of viscosity upsprings, and this will have a strong impact on the sensitivity of button, even may have the unresponsive risk of button.This mode is more difficult for realizing independent touch key-press in On-cell product or In-cell product, and less stable, and Making programme is also relatively complicated.
Summary of the invention
The purpose of this utility model is the defect existed for above-mentioned prior art, a kind of touch display module with independent touch key-press is provided, comprise the backlight, touch-screen glass, optical cement, ITO layer and the cover plate that stack gradually, described ITO layer has several receiving cables and transmission channel, also comprise the transparent conductive sheets of at least one band key legend, described transparent conductive sheets one side is coupled with described ITO layer by receiving cable and transmission channel, and another side and cover plate fit.
In one embodiment, touch-screen glass is for certainly holding touch-screen, and each is a passage to receiving cable and transmission channel, and described transparent conductive sheets is coupled with described passage.
In another embodiment, touch-screen glass is mutual tolerance touch-screen, and described receiving cable and transmission channel are two separate passages, the receiving cable that described transparent conductive sheets is corresponding different respectively, and shares transmission channel.
The utility model is by arranging two-layer ITO layer, one deck is the ITO layer of mobile phone module itself, another layer is the transparent conductive sheets of band key legend, be coupled by the secondary of electric capacity, the signal of the viewing area of touch-screen glass is extended in the Petting Area beyond viewing area, achieve Independent keys, solve Oncell product and Incell product independence touch key-press and realize difficulty and poor stability problem, also solve Oncell product and Incell product when having an Independent keys simultaneously, module can not inversion problem, and the flow process of the making of Independent keys is also very simple, reduce security risk.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is cut-open view of the present utility model.
Embodiment
Be described further the utility model below in conjunction with accompanying drawing, following embodiment is all described for mobile phone.
As shown in Figure 1, the utility model is coupled by the secondary of electric capacity, is extended to by the signal of the viewing area of touch-screen glass in the Petting Area beyond viewing area, for the realization of the touch panel function Independent keys integrated with liquid crystal panel provides thinking and solution.
The touch display module with independent touch key-press that the utility model proposes, comprise the backlight 5 stacked gradually, touch-screen glass 4, optical cement 3, ITO layer 2 and cover plate 1, ITO layer 2 has some transmission channels and receiving cable, the transparent conductive sheets being with key legend is provided with between ITO layer 2 and cover plate 1, the quantity of transparent conductive sheets is pressed bond number according to required and determine, in the present embodiment, be provided with three buttons, therefore the quantity of transparent conductive sheets is 3, all be positioned at the Petting Area beyond viewing area, transparent conductive sheets one side is coupled with ITO layer 2 by receiving cable and transmission channel, another side and cover plate 1 fit, the material of transparent conductive sheets can adopt ITO, or Nano Silver, or Graphene etc.
When touch-screen glass is in time holding touch-screen, every bar passage of ITO layer 2 can transmit and receive signal, its transmission channel i.e., receiving cable is a passage, only need to arrange Coupling point (A place) in the position that certain passage is corresponding, Petting Area beyond viewing area arranges transparent conductive sheets (B place), transparent conductive sheets is connected with Coupling point by passage, when extraneous conductor (finger of people) touch key-press (B place) on cover-plate glass, transparent conductive sheets can be made to produce a detectable semaphore, by analog-to-digital conversion and algorithm process, the condition that the button that this semaphore changes into triggers, namely a button only needs a passage, three buttons only need three passages.
When touch-screen glass is mutual tolerance touch-screen, transmission channel and the receiving cable of ITO layer 2 separate, all Coupling point will be done at receiving cable and position corresponding to transmission channel, transparent conductive sheets is connected with the Coupling point of ITO layer, again the Coupling point on the Coupling point of transparent conductive sheets and cover plate or screen body is sticked together by optical cement, coupling is produced in the process of discharge and recharge, form fixing coupling capacitance, at high frequencies, the key induced pattern being equivalent to shield receiving cable on body and making is switched on.The key induced pattern of ITO below button delivers to receiving cable signal by Coupling point, when extraneous conductor (finger) is near button, the semaphore that receiving cable receives can change, after the knots modification of signal transforms and calculates and processes, and can as the trigger condition of button.Namely a button needs two passages, and three buttons need four passages.
The signal of scanning is when being communicated to Coupling point (A place), can be coupled with transparent conductive sheets (B place), whole key legend is charged, when finger touch button B place (transparent conductive sheets), B place electromotive force changes, thus affects the electromotive force of whole transparent conductive sheets, at this moment the receiving cable shielded on body affects by ITO, also can change, by the detection to down channel, can judge that whether there occurs button touches.
Whole process time is very short, but needs to draw by calculating to signal be us to be at touch A place or at touch B place.Due to the difference of model around the characteristic sum of model, touch event can be told from button (transparent conductive sheets region) or viewing area (ITO layer region).
Above specific embodiment is only in order to illustrate design of the present utility model, and those of ordinary skill in the art can make various deformation and change under design of the present utility model, and these distortion and change include within protection domain of the present utility model.
