According to the capacitive touch screen on the refrigerator, a simple key type capacitive touch screen is adopted, and the capacitive touch screen can not only achieve a slide effect of a dot matrix touch screen, but also is cheap in price.
Description
Technical field:
The utility model relates to the capacitive touch screen on a kind of refrigerator.
Background technology:
Along with the continuous expansion in the consumer electronics product markets such as multimedia and intelligent terminal, and the consumer is to the continuous lifting of man-machine interaction experience sense demand, and touch-screen more and more pours in the daily life.Touch-screen can be divided into five basic kind: vector pressure sensing technology touch-screen, resistive technologies touch-screen, capacitance technology touch-screen, infrared technology touch-screen, surface acoustic wave technique touch-screen.Wherein to have reaction velocity fast for capacitance touch screen, the advantages such as stable performance, life-span length, product overall appearance.Capacitance touch screen divides key type touch screen and dot matrix touch-screen.The key type touch screen touch-screen only adopts the ITO of individual layer, when the finger touch screen surfaces, just has a certain amount of electric charge and transfers to human body.In order to recover these loss of charge, electric charge replenishes into from four jiaos of screen, and the quantity of electric charge that all directions are replenished and the distance of touch point are proportional, and we can extrapolate the position of touch point thus.The dot matrix touch-screen is to be made into laterally and the longitudinal electrode array with ITO at glass surface, and these horizontal and vertical electrodes consist of electric capacity with ground respectively, and this electric capacity is exactly usually said self-capacitance, namely electrode electric capacity over the ground.When finger touch arrived capacitance plate, the electric capacity of finger will be added to and shield on the body capacitance, and screen body capacitance amount is increased.When touching detection, the self-capacitance screen detects respectively laterally and the longitudinal electrode array successively, according to the variation that touches front and back electric capacity, determines respectively lateral coordinates and along slope coordinate, then is combined into the touch coordinate on plane.The scan mode of self-capacitance is equivalent to the touch point on the touch-screen is projected to respectively X-axis and Y direction, then calculates coordinate in X-axis and Y direction respectively, is combined at last the coordinate of touch point.More than the cost of two kinds of capacitance touch screens all higher.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide the capacitive touch screen on a kind of refrigerator, adopts a kind of easy button capacitance touch screen, not only can realize sliding effect but also the low price of dot matrix touch-screen.
The utility model technical solution problem adopts following technical scheme:
Capacitive touch screen on a kind of refrigerator, it comprises:
Indium oxide tin film (ITO film) and cover transparent covering layer on the described indium oxide tin film;
Described indium oxide tin film is provided with touch key-press, and described touch key-press links to each other with the touch sensible chip by circuit;
Described touch sensible chip is connected with the control system display by flexible PCB (FPC).
Design feature of the present utility model also is:
Described touch key-press is sliding strip type button or some independently single buttons.
Fit tightly without bubble between described overlayer and the described indium oxide tin film.
Described overlayer is clear glass or transparent plastic.
In the concrete scheme: the number of touch key-press is decided according to the touch effect of touch-screen realization and what and density degree of touch-screen contact, need fit tightly between ITO film and the overlayer, and can not there be bubble the centre.Obtain the effect of final contact position and realization slip by the noise value of calculating single or multiple buttons; Touch key-press is connected with the touch sensible chip, and the collection signal of touch key-press is also inputted the touch sensible chip, and the touch sensible chip is exported corresponding signal to the control system of display through after detecting and calculating.Touch-screen is as follows with the method for door body glass gluing: 1) at the attached one deck double faced adhesive tape in the XX district of touch-screen, the operational zone of touch-screen is bonded together the two with after a viewfinder area of body glass aligns; 2) behind touch-screen and the door body glass gluing, its edge sealant sealing is to guarantee the stable of touch screen operation district internal environment.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, be provided with touch key-press at the ITO film, the touch key-press position is corresponding with key icon position on the display.Can realize simply touching effect, require not many common capacitance touch screen refrigerator with respect to the contact, cost greatly reduces.
2, obtain the effect of final contact position and realization slip on the refrigerator capacitance plate by the noise value of a plurality of buttons (draw runner button).
3, because touch key-press is sliding strip type button or some independently single buttons, the single button of finger crawl can be realized the effect that crawl touches, and when finger slides to the draw runner button, can realize the display picture sliding effect.
Description of drawings:
Fig. 1 is capacitive touch screen structure figure of the present utility model.
Fig. 2 is the utility model touch key-press control system synoptic diagram.
Number in the figure: 1 overlayer, 2 indium oxide tin films, 3 touch sensible chips, 4 flexible PCBs, 5 control system displays, 6 touch key-presss, 7 sliding strip type buttons, 8 display control systems.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: referring to Fig. 1, present embodiment be used for capacitive touch screen on the refrigerator, it comprises:
Indium oxide tin film 2 and cover transparent covering layer 1 on the indium oxide tin film; Indium oxide tin film is provided with touch key-press 6, and touch key-press 6 links to each other with touch sensible chip 3 by circuit; Touch sensible chip 3 is connected with control system display 5 by flexible PCB 4.
In specifically arranging, capacitive touch screen has three-decker, and ground floor is overlayer 1, and overlayer is transparent material, can be glass, plastics that also can be transparent, the second layer are ITO film (indium oxide tin film), have good electric conductivity and the transparency, be provided with capacitance touch button on the ITO film, the 3rd layer is display, the information that Shows Picture, and the position of touch key-press is corresponding with the key icon that display shows on the ITO film.To fit tightly between overlayer and the ITO film, bubble must not be arranged.
Fig. 2 is the utility model touch key-press control system synoptic diagram: be provided with touch key-press 6 at the ITO of capacitance touch screen film, the single-point touches button can be realized single-point touches, sliding strip type button 7 can be realized sliding function, the single-point touches button is exactly the large-scale conductor piece that connects touch sensible, wherein measured capacitance can be made comparisons with a series of critical value, and measurement result also can obtain by numeral output, or uses other analog feature, with pressure or the finger area of further sensing shake-up.Then be that many conductor pieces are consisted of with straight line or radial arrangement as for the sliding strip type button.Utilize the algorithm that calculates barycenter just can determine the position of contact.Touch sensible chip 3 is exported corresponding signal to display control system 8 after detecting signal and calculating.Display control system 8 calculates corresponding icon button by computing, shows corresponding function.
