Abstract

The utility model provides a touch display device, comprising a touch screen and a shell on which a groove is arranged. The touch screen is arranged inside the groove. A touch sensor layer is arranged on the touch screen, and a surface decorative layer is adhered and coated on the upper surface of the touch sensor layer. After the surface decorative layer is adhered and coated on the surface of the touch sensor layer of the touch display device, the device can be controlled by operating the touch sensor layer only through touching the corresponding position indicated on the surface decorative layer. Meanwhile, the adoption of the surface decorative layer adhered and coated on the surface of the touch screen makes the plane effect of the device better, enhances the hand feeling of operation and improves the aesthetic perception of products, thereby solving the problems of poor hand feeling, low impacting and dropping resistance capacity due to the arrangement of the key-press on the shell in the prior art.

Description

A kind of touch display device

Technical field

The utility model belongs to a kind of electronic equipment, relates in particular to a kind of touch display device.

Background technology

Along with the continuous development of electronic technology, people's life style is more and more tended to simple and convenient.For various electronic products, people's requirement is not only that it is multiple functional, but also needs outward appearance beautiful, and the function practicality uses simple and convenient.

As shown in Figure 1, with touch-screen mobile phone common on the present market is example, for the user easy to use, though on touch-screen 11, show the function key of said function, but also can be provided with as receiving calls on the phone housing 12 usually, close simple key-press 13 such as conversation, make the user need not to pay close attention to the displaying contents of touch-screen, 13 just can operate as long as optionally push button.Offer groove on the phone housing 12, above-mentioned touch-screen 11 is arranged in this groove, blocked by shell 12 around it, and chain of command reveals for the user and operates.Its shortcoming is, because shell 12 needs card to establish touch-screen 11, makes button 13 surfaces on the shell 12 be higher than touch-screen 11 surfaces, has influenced the feel the when user operates.In addition, the button of setting up 13 has also increased the weight of mobile phone, and anti-ly falling of making mobile phone, anti-dropping capability are relatively poor.

The utility model content

The technical problems to be solved in the utility model is, a kind of touch display device is provided, good hand touch and anti-ly fall, anti-dropping capability is better.

In order to solve the problems of the technologies described above, the utility model provides a kind of touch display device, comprises touch-screen and shell, offer groove on the shell, touch-screen is arranged in the groove, and described touch-screen has touch sensitive layer, has sticked surface decoration layer in the touch sensitive layer upper surface.

After the touch sensible laminar surface that touches display device sticks surface decoration layer, only need the relevant position of indicating on the touch-surface decorative layer, just can operate touch sensitive layer and come control appliance.Simultaneously, adopt surface decoration layer to stick on touch-screen, make the plane effect of equipment good, strengthened the feel the when user operates, and make product more attractive in appearance, solved in the prior art owing on the shell button is set, and the operating handle of having brought is poor, and anti-ly fall, problem such as anti-dropping capability is relatively poor.

Embodiment

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

See also Fig. 2 and Fig. 4, the utility model embodiment provides a kind of touch display device, comprises touch-screen 21 and shell 22.Offer stair-stepping groove 221 on the shell 22, touch-screen 21 is arranged in the groove 221.Touch-screen 21 has touch sensitive layer 211, has sticked surface decoration layer 23 in touch sensitive layer 211 upper surfaces.

Please together consult Fig. 3, be printed with key icon 232 on the above-mentioned surface decoration layer 23, in the present embodiment key icon 232 have receive calls, hang up the telephone, function button signs commonly used such as PPS MOVIE, GPS, MUSIC, these key icon 232 are corresponding with the function key position on the touch-screen 21.Like this, the user only needs key icon 232 on the touch-surface decorative layer 23 just can realize the control of touch-screen 21 accordingly.

Because content displayed refreshes along with user's operation may constantly change on the touch-screen 21, therefore also is provided with the zone 231 of transparent demonstration on surface decoration layer 23, this viewing area 231 is corresponding with the control interface of touch sensitive layer 211.Like this, just touch-screen 21 can be operated in this viewing area 231, to control the function menu on the interface according to demand.

Surface decoration layer 23 can also extend to shell 22 surfaces, and it sticks after on the shell 22, can print the LOGO (logogram writes a Chinese character in simplified form, sign, logo, trade mark) of individual pictures or product on surface decoration layer 23, makes product more attractive in appearance.

As shown in Figure 4, in the present embodiment, touch-screen 21 is for having the resistive touch screen of surface decoration layer 23, its touch sensitive layer 211 comprises ITO (Indium Tim Oxide, phosphide tin compound) conductive film 211b and substrate 211a, ITO conductive film 211b and substrate 211a are symmetrical arranged respectively and have two-layerly up and down, and substrate 211a is positioned at the outside of ITO conductive film 211b, and surface decoration layer 23 sticks in the upper surface of top substrate layer 211a.In following laminar substrate 211a arranged outside PC (Polycarbonate, Merlon) plate 212 is arranged, this PC plate 212 is used to support touch sensitive layer 211, is difficult for being bent to guarantee touch-screen 21.In addition, between upper and lower laminar substrate 211b, also be provided with and extraneous FPC (Flexible PrintCircuit, the flexible circuit board) connecting plate 213 that is connected, to realize the touch control function of touch-screen 21.

Touch-screen 21 can also be the touch-screen of condenser type or other types, as long as touch-screen 21 is provided with surface decoration layer 23, all within protection range of the present utility model.

Surface decoration layer 23 can adopt PET (Polythylene Terephthalate, polyester resin) material to make, and makes product quality lighter, satisfies the demand in market.

After sticking surface decoration layer 23 in touch sensitive layer 211 surfaces that touch display device, only need the relevant position of indication on the touch-surface decorative layer 23, just can operate touch sensitive layer 211 and come control appliance.Simultaneously, adopt surface decoration layer 23 to stick on touch-screen 21, can make the plane effect of equipment good, strengthened the feel the when user operates, and make product more attractive in appearance, solved in the prior art owing on the shell button is set, and the operating handle of having brought is poor, and anti-ly fall, problem such as anti-dropping capability is relatively poor.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
