End etc..For electronic equipment shown in Figure 15 by taking the mobile terminal of cell phone type as an example, right above-mentioned display module is equally applicable to other conjunctions
Suitable electronic product, it is not limited to the mobile terminal of cell phone type.
Specifically, the front of the mobile terminal 3 is equipped with a display panel 100, is equipped with protection cap above the display panel 100
Plate 300.Optionally, the screen of the display panel 100 accounts for relatively high, such as 80% or more.Screen accounting refers to the aobvious of display panel 100
Show that region 101 accounts for the ratio of the front surface region of mobile terminal 3.The photosensitive panel 200 is correspondingly arranged at the upper of the display panel 100
Side, and it is located at 300 lower section of cover sheet.The photosensitive panel 200 is for sensing in contact with or close to the display area of display panel 100
The predetermined biological information of the target object of 101 any positions.
When mobile terminal 3 is in bright screen state and is in biological information sensing modes, the display panel 100 hair
Optical signals.When an object is in contact with or close to the viewing area, which receives is believed by the reflected light of the object
Number, the optical signal received is converted as corresponding electric signal, and is believed according to the predetermined biological characteristic that the electric signal obtains the object
Breath, for example, information in fingerprint.To which, the photosensitive panel 200 can be realized in contact with or close to 101 any position of display area
Target object sensed.
In the electronic equipment of the utility model embodiment, have the advantages that
The first, photosensitive panel is bonded with display panel, and realizes target object using the optical signal that display panel issues
Biological information sensing, does not need that light source additionally is arranged, to not only save the cost of electronic equipment, and also achieves
Biological information sensing is carried out to the target object of the display area any position of contact display panel.Moreover, the display mould
It after photosensitive mould group can be separately made in group, then is assembled with display device, to accelerate the preparation of electronic equipment.
Second, since target object different parts have differences the reflection of optical signal, feel between adjacent photosensitive unit
The optical signal measured can have aliasing, so that it is fuzzy to cause the sensitive information obtained, therefore the utility model embodiment passes through
Anti-aliasing image-forming component is set, it is therefore prevented that the received optical signal of adjacent photosensitive unit generates aliasing, improves photosensitive mould group
Sense precision.
Photosensitive panel is located above display panel, therefore directly arrives through the reflected optical signal of target object by third
The sensing precision of photosensitive mould group is improved up to photosensitive panel so as to avoid the interference of other substances during optical signal transmission.
Further, the electronic equipment further comprises a touch sensor (not shown), the touch sensing
Device is used to the touch area of the target object is determined, with electronic device when a target object contacts the cover sheet
Biological information sensing is executed in the touch area.
In some embodiments, the touch sensor perhaps with the cover sheet 300 is integrated or and photosurface
Plate 200 is integrated, or integrated with display panel 100.By integrated touch sensor, the touching to target object is not only realized
Detection is touched, and also reduces the thickness of electronic equipment, is conducive to electronic equipment and develops towards lightening direction.
