Description
Technical field
The utility model relates to electronic technology field, relates in particular to a kind of capacitive touch screen touch terminal.
Background technology
Along with the development of electronic technology, touch screen technology application is more and more extensive, as mobile phone, e-book, PAD panel computer) etc. all using touch-screen.
Touch-screen comprises capacitive touch screen and resistive touch screen, and wherein, resistive touch screen need come in contact each layer of screen with pressure and realize various operations, and therefore, sensitivity is poor; And can not realize multiple point touching operation, still, resistive touch screen precision is higher, can reach single display pixel.Capacitive touch screen is realized various operations by electrostatic induction, and sensitivity is better, and can realize multiple point touching, and still, precision is lower, generally wants several pixels.
For existing touch-screen, utility model people finds that in prior art, at least there are the following problems: the continuous increase along with user's request, the requirement of touch-screen is also increased gradually, as, in the process of playing games, require to have very high sensitivity and multiple point touching operation; In writing process, as kept a record in e-book or writing microblogging, need precision higher, but capacitive touch screen of the prior art or resistive touch screen all can not reach above-mentioned requirements simultaneously.
Utility model content
For the problems referred to above, the utility model aims to provide a kind of capacitive touch screen touch terminal.
For realizing this technical purpose, scheme of the present utility model is: a kind of capacitive touch screen touch terminal, capacitive touch screen control circuit is connected with capacitive touch screen, electric resistance type touch screen control circuit is connected with resistive touch screen, capacitive touch screen control circuit is in parallel with electric resistance type touch screen control circuit, described power supply power supply and two-way switch are connected in circuit, wherein, described capacitive touch screen control circuit makes touch-screen support finger touch operator scheme, and described electric resistance type touch screen control circuit makes touch-screen support writing pencil operator scheme; When described two-way switch and described capacitive touch screen control circuit conducting, described capacitive touch screen control circuit, described two-way switch, the series connection of described power supply.Now, user operates by capacitive touch screen, and touch-screen is supported finger touch operator scheme, and Operational Figure Of Merit is higher and can realize multiple point touching operation.
Beneficial effect
The utility model realizes that sensitivity is higher, the operation of multiple point touching operation, degree of precision.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model reality.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.As shown in Figure 1, the utility model embodiment provides a kind of capacitive touch screen touch terminal, comprising: the capacitive touch screen control circuit 1 being connected with capacitive touch screen, the electric resistance type touch screen control circuit 2 being connected with resistive touch screen, power supply 3 and two-way switch 4.Wherein, described capacitive touch screen control circuit 1 makes touch-screen support finger touch operator scheme, and described electric resistance type touch screen control circuit 2 makes touch-screen support writing pencil operator scheme; When described two-way switch 4 and 1 conducting of described capacitive touch screen control circuit, described capacitive touch screen control circuit 1, described two-way switch 4,3 series connection of described power supply.Now, user operates by capacitive touch screen, and touch-screen is supported finger touch operator scheme, and Operational Figure Of Merit is higher and can realize multiple point touching operation.
The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection domain of technical solutions of the utility model.
