Abstract
The utility model relates to the combination of a touch screen and a display, which comprises a display and a touch screen used to locating the functions indicated by the display. A transparent glue layer is coated between the display and the touch screen. The the combination of the touch screen and the display utilizes the glue layer to replace the prior air layer between the touch screen and the display and the traditional double-faced adhesive tape used for conglutination, meanwhile, the glue layer fills up the traditional air layer between the touch screen and the display, as a result, the scattering of the air layer is avoided, the saturation and the contrast of colors are increased, the light transmission is increased, and therefore the display effect is improved. Moreover, by silkscreening the glue layer on the whole surface of the display, the adhesive strength between the touch screen and the display can be greatly enhanced. Furthermore, the solidified glue layer has a certain cushioning effect for the stress of the touch screen, thus increasing the shock resistance of the touch screen.
Description
Technical field
The utility model relates to the combination of a kind of touch-screen and display, be specifically related to a kind of scattering of avoiding air layer, increase color saturation and contrast, improve display effect, and can increase the touch-screen of impact resistance of touch-screen and the combination of display.
Background technology
Existing touch-screen is as a kind of up-to-date computer input equipment, and it is simple, convenient, the most natural present a kind of man-machine interaction mode.Along with growing with each passing day of multimedia information inquiry, people speak of touch-screen more and more, because touch-screen is not only applicable to the national conditions of Chinese multimedia information inquiry, and touch-screen have sturdy and durable, reaction velocity fast, save the space, be easy to many advantages such as interchange.Utilize this technology, the user needs only the icon or the literal that bump lightly on the computer display with finger just can realize the operation to main frame, thereby makes man-machine interaction more simple and direct, and this technology greatly facilitates those users who is ignorant of computation.The system designer of developed country and our country take the lead in courageously using the system designers of touch-screen to know: touch-screen is not dispensable thing in the utilization in various fields, and equipment is absolutely necessary.
Please refer to Fig. 1, be depicted as the constitutional diagram of traditional touch-screen 10 ' and LCD 30 '.The middle part of described LCD 30 ' is for showing the viewfinder area 32 ' (Visual Area) of usefulness.The assembling on traditional touch-screen 10 ' and LCD 30 ' surface all is that the viewfinder area 32 ' in LCD 30 ' sticks a circle double faced adhesive tape 18 ' on every side, by described double faced adhesive tape 18 ' touch-screen 10 ' and LCD 30 ' is bonded together.
But, being fitted on the LCD with double faced adhesive tape because traditional touch-screen is general direct, the bounding force between described touch-screen and the LCD is relatively poor relatively, is easy to come off because of use or oxidation for a long time each other.And, so between described touch-screen and the LCD because can form one deck air layer across layers of two-sided, the existence of described air layer can bring the scattering of light to a certain degree, and influence the light transmission rate of touch-screen, also further reduced the saturation degree and the contrast of the shown color of display.
So, demand a kind of new touch-screen and the combination of display urgently and can solve the problem that occurs in above-mentioned conventional touch screen and the display combinations.
Summary of the invention
The purpose of this utility model is the defective that overcomes above-mentioned prior art, provides a kind of bounding force stronger, eliminates the touch-screen of air layer and the combination of display.
Another purpose of the present utility model provides a kind of display effect and raising light transmission rate of improving, simultaneously can be to the stressed combination of playing the touch-screen and the display of buffer action of touch-screen.
In order to achieve the above object, the technical solution of the utility model is: the combination of a kind of touch-screen and display, comprise display and the touch-screen that is used for the indicated function of locating and displaying device, it is characterized in that: be covered with transparent glue layer between described display and the touch-screen.
Preferably, described glue layer is coated with to expire and comprises on the surface in form territory in the display front portion.
Preferably, described display is a LCD.
Further, described transparent glue layer is colourless.
Described transparent adhesive tape water layer adopts the photocuring colloid.
The utility model adopts described technical scheme, its beneficial technical effects is: 1) touch-screen of the present utility model, by adopting the water white transparency glue layer to replace double faced adhesive tape and air layer between original touch-screen and the display, described glue is filled the air layer between former touch-screen and the LCD, avoid the scattering of air layer, increase color saturation and contrast, thereby improve display effect; 2) touch-screen of the present utility model can increase bond strength between touch-screen and the display greatly at whole silk-screen glue layer on the display surface; 3) touch-screen of the present utility model behind the original air layer of the glue layer replacement that is covered with display, has been avoided having increased light transmission rate simultaneously because there is the scattering that brings in air layer; 4) touch-screen of the present utility model, described glue layer are to adopt silk screen printing process to be coated with to expire on LCD, adopt the web plate of suitable order number to cooperate glue can control the thickness of described glue layer, and can guarantee the homogeneity of glue thickness; 5) touch-screen of the present utility model, described glue layer have certain buffer action to touch-screen stressed after solidifying, can increase the impact resistance of touch-screen.

Fig. 2 is the package assembly synoptic diagram of the combination of the utility model touch-screen and display.
Embodiment
Also in conjunction with the accompanying drawings the utility model is further described below by specific embodiment.
Please refer to Fig. 2, the utility model relates to the combination of a kind of touch-screen and display, comprises display 30 and the touch-screen 10 that is used for locating and displaying device 30 indicated functions.Be provided with transparent glue layer 20 between described display 30 and the touch-screen 10.
Described touch-screen can be used on the user interface of various man-machine interactives, such as: the service inquiry display system; On the electric equipments such as leader's office equipment, mobile phone, Digital Video or digital camera.In the present embodiment, will with the mobile phone example.Can directly carry out operational order to the icon on the display by touch-screen, and by the described operational order of the microprocessor processes of mobile phone.
Described touch-screen 10 can adopt resistive touch screen, perhaps capacitive touch screen, perhaps infrared-type touch-screen, perhaps surface acoustic wave touch screen.For clearer explanation concrete mode of the present utility model, in the present embodiment, described touch-screen 10 adopts resistive touch screen, utilizes pressure sensitive to control.In simple terms, described touch-screen 10 has the coordinate of driving dot matrix, comprises substrate, is coated with the full first transparent oxidized metal conductive layer (ITO) and the second transparent oxidized metal conductive layer on substrate.Be separated with web plate between described first, second transparent oxidized metal conductive layer.During use, touch-screen 10 is when being under pressure, and described first, second transparent oxidized metal conductive layer sees through web plate and produces contact in the position, touch point, and the resistance of position, described touch point changes, on X and Y both direction, produce signal, generate the coordinate dot matrix signal.Detect and gather the coordinate dot matrix positional value of touch point by detection part is set in the mobile phone, transfer to then touch screen controller judge described touch point the corresponding operational order that activates.The microprocessor of last mobile phone is finished corresponding operation and function according to instruction.
