In some embodiments, control module 30 is used to control the same time point of part display pixel in k display pixel
It is bright, wherein while the display pixel lighted forms a corresponding pattern, and the pattern may be the same or different.One is real
It applies in mode, which is located substantially at the center of predetermined display area, so that the finger of user is located at the pattern
When upper, it was able to achieve finger print information and accurately acquires.As shown in figure 8, the electronic equipment that Fig. 8 is the utility model is in breath screen state
The display schematic diagram of lower fingerprint input one embodiment of pattern.It should be noted that the display area of display screen is except pre- in Fig. 8
The fingerprint input pattern determined in the S2 of display area is illuminating state, remaining position is OFF state, and predetermined display area
S2 is not also shown, here just to for illustrating the positional relationship of predetermined display area and fingerprint input pattern.Fingerprint in Fig. 8
Input pattern is located substantially at the center of predetermined display area S2, and at predetermined time intervals, which inputs the aobvious of pattern
Show that small-scale movement can occur for position, due to being small-scale movement, user's experience is barely affected.Moreover,
Pattern is inputted by the mobile fingerprint of small range, the same display pixel avoided in display screen predetermined display area S2 is long
The problem of time lights, and be easy to cause the display pixel aging improves the service life of electronic equipment display screen and using effect
Fruit.
As shown in figure 9, the electronic equipment that Fig. 9 is the utility model is in fingerprint input another implementation of pattern under breath screen state
The display schematic diagram of mode.It should be noted that the display area of display screen is except the fingerprint in predetermined display area S2 in Fig. 9
Input pattern is illuminating state, remaining position is OFF state, and predetermined display area S2 is not also shown, is only here
For illustrating the positional relationship of predetermined display area and fingerprint input pattern.Fingerprint input pattern is located at predetermined display in Fig. 9
In region, and at predetermined time intervals, the display position of fingerprint input pattern can be moved.It is twice shown in addition, adjacent
Fingerprint input pattern is not overlapped, and the display pixel for thus avoiding fingerprint input pattern is lighted for a long time, be easy to cause the display
The problem of pixel ageing, improves the service life and using effect of electronic equipment display screen.
As shown in Figure 10, Figure 10 is that the electronic equipment of the utility model is in the fingerprint input another reality of pattern under breath screen state
Apply the display schematic diagram of mode.It should be noted that the display area of display screen is except the finger in predetermined display area S2 in Figure 10
It is illuminating state that line, which inputs pattern, remaining position is OFF state.Fingerprint input pattern is predetermined display area S2 in Figure 10
Boundary position, and multiple display pixels at the predetermined display area boundary position are divided into multiple groups, each group of display picture
Corresponding fingerprint input pattern is formed when vegetarian refreshments is bright.When electronic equipment is in breath screen state, at predetermined time intervals, which refers to
It is switched between line input pattern, as pattern is alternately displayed with pattern in Figure 10 right hand page in Figure 10 left hand page.
Pattern is inputted by the fingerprint, predetermined display area is defined, prompts user that finger is placed in the predetermined display region with this
In domain, the unlock operation of electronic equipment can be carried out.The fingerprint inputs the display of pattern, avoids same display pixel for a long time
The problem of lighting, be easy to causeing the display pixel aging improves the service life and using effect of electronic equipment display screen.
It should be noted that above are only the display mode for illustrating fingerprint input pattern, it is not limited to which this is practical
Novel claimed range.As long as carrying out ground various modifications knot under the core concept lighted based on same display pixel interval
Structure and mode, in the protection scope of the utility model.For example, since the pel spacing between the display pixel of display screen is non-
It is often small, therefore when carrying out the display of fingerprint input pattern, the display pixel interval of control fingerprint input pattern is lighted, so both
It can show that the fingerprint inputs pattern, in turn avoid same display pixel and light for a long time, be easy to cause the display pixel aging
Problem improves the service life and using effect of electronic equipment display screen.
In some embodiments, while the display pixel lighted is disposed adjacent or is spaced setting.
In some embodiments, predetermined display area is the shapes such as rectangle, square, circle, ellipse.
Further, referring to Fig.1 1, Figure 11 be in Fig. 1 electronic equipment along the cross-section structure of the another embodiment of I-I line
Schematic diagram.The electronic equipment further comprises touch sensing module 40, which is located at the light out of display screen 20
Side, the i.e. top of display screen 20.Certainly, which also can integrate in display device, so that the display device
For the touch display screen with touch-control and display function.The touch sensing module 40 is for example including capacitive sensing module, resistance
Whether formula sensing module, optical profile type sensing module, pressure type sensing module etc. have object touching for detecting on display screen 20
It touches, the touch location of object and touch operation type etc. on display screen can determine that according to the testing result.
Control module 30 is further used for: when electronic equipment is in breath screen state, providing third driving signal to touch
Sensing module 40, driving touch sensing module 40 executes touch detection, when determining in predetermined display area has object touch, to
Fingerprint identification module 10 provides the second driving signal, and driving fingerprint identification module 10 acquires finger print information.
The utility model embodiment and the difference of above-mentioned first embodiment are: when electronic equipment is in breath screen state
When, touch sensing module 40 is still in working condition, for detecting to the touch operation on display screen 20.Control module 30
According to the testing result of touch sensing module 40, whether have object touch and touch location, into one if can determine on display screen
Step judges whether touch location is located in presumptive area, is to have object touch in determining presumptive area, otherwise in presumptive area
There is no object touch.Only when determining in predetermined display area has object touch, fingerprint identification module 10 is just waken up, with driving
Fingerprint identification module 10 acquires finger print information.In this way, power consumption when not only reducing electronic equipment breath screen state, and also avoid
Fingerprint identification module is constantly in working condition, to extend the service life of fingerprint identification module.
When there is object touch in the predetermined display area for determining display screen 20, fingerprint identification module 10 is not only waken up, together
When also control display screen 20 predetermined display area all light.In the utility model embodiment, when being lighted using display screen
Light source of the optical signal of sending as fingerprint identification module, the acquisition of Lai Jinhang finger print information.In this way, making the fingerprint recognition mould
Block does not need that light source additionally is arranged, and can be achieved with the acquisition of finger print information, thus further save fingerprint identification module at
This.
