Description
Technical field
This utility model relates to a kind of input equipment with fingerprint sensor and the portable electric appts comprising it.
Background technology
Recently, along with masses' raising to the attention rate of the portable electric appts such as smart mobile phone (smartphone) or panel computer (tabletPC), the research and development of correlative technology field also carry out in high gear.Portable electric appts is a kind of input equipment for receiving the particular command from user, and most cases is the built-in touch screen (touchscreen) with being integrally formed of display screen as display device.Further, portable electric appts also includes various function key (functionkey) or soft key (softkey) etc. as input equipment except touch screen.
Fig. 1 illustrates the general shape of smart mobile phone in portable electric appts.With reference to Fig. 1, before portable electric appts 1000, it is provided with display screen portion 1100.Display screen portion 1100 includes the touch screen of capacitance-type, at this, if the health of user (finger etc.) contacts with display screen portion, then by detecting the static capacity change of built-in capacitor, whether touches thus detecting.
The touch screen of capacitance-type has advantages below: is swift in response and does not need other input tools, and can multi-point touch.But having the disadvantage that, touch screen must be carried out the touch of more than predetermined area or pressure and just can be detected by user, therefore, it is difficult to carry out fine input.
In order to solve the problems referred to above, introduce the touch screen technology utilizing time writer.Time writer is also referred to as EMR electromagnetic resonance (EMR:Electro-MagneticResonance) pen, and inside is built-in with capacitor and coil.Touch screen is provided with loop coil, and the electromagnetic wave making loop coil On current and produce can be absorbed by time writer, and time writer discharges the electromagnetic wave absorbed with specific frequency, the loop coil of touch screen absorbs the electromagnetic wave of this characteristic frequency again, such that it is able to the position of detection time writer.The touch screen input mode utilizing time writer gives user's sensation with familiar note tool, and can transmit finer touch sense.Further, when user in order to make hands touch touch screen with pen, it is also possible to optionally only identify the input of pen.
Recently, in conjunction with capacitive way and time writer mode, thus the composite touch screen that can use in both cases is developed and become universal.
It addition, the bottom of portable electric appts 1000 can be formed for performing home key 1200 and the function key 1300 confirming to perform, cancel, show the several functions such as menu, return.This home key 1200 or function key 1300 are the input equipment independent with the display screen portion 1100 with touch screen, can be the input of the key of mechanical switch mode or the capacitance-type identical with display screen portion 1100 or time writer mode in theory, but in practice, the reasons such as the restriction because of receiving space, use the key (being mainly used in home key 1200) of mechanical switch mode or the sensor (being mainly used in function key 1300) of capacitance-type.
Therefore, time user inputs order by time writer mode to display screen portion 1100, there is the multiple inconvenience needing to come in user's experiences such as touch function keys 1300 with finger rather than time writer in order to use function key 1300.
It addition, recently along with the safety of portable electric appts is paid attention to, home key 1200 introduces the form of built-in fingerprint sensor.Fingerprint sensor is the sensor of the finger print of detection people, and it carries out login or the authenticating step of user by fingerprint sensor, thus protecting the data stored in electronic equipment, and prevents security incident in advance.
Further, in portable, also the navigation feature performing the pointer operations such as cursor can be incorporated into fingerprint sensor.In addition, also the switching function received from the information of user can be incorporated into fingerprint sensor.
But the function key 1300 of the home key 1200 of existing fingerprint sensor form and capacitance-type is separately installed on electronic equipment, so being respectively necessary for independent technique, the problem such as non-efficient activity and expense increase of therefore there is technique.And as described above, when display screen portion 1100 supports the input of time writer, function key 1300 also can bring the inconvenience in experience when using time writer to user.
So, need the exploitation of the input equipment being built-in with the fingerprint sensor that can solve the problem that these problem points and the portable electric appts that comprises it badly.
