Sn is spaced cloth in X direction If.So, ground is changed, which does not limit shown in Fig. 5 with multiple data lines 202 is vertically arranged, can also be with Setting at an angle, such as 30 °, 60 ° etc..In addition, since scan line 201 and data line 202 are conductive, because herein It will be isolated by insulating materials between the scan line 201 and data line 202 of crossover location.

It should be noted that above-mentioned scan line 201 and the distribution of data line 202 and the setting of quantity are not limited to The embodiment enumerated is stated, corresponding scanline groups and data can be correspondingly arranged according to the difference of the structure of photosensitive unit 22 Line group.

Further, multi-strip scanning line 201 is all connected with a photosensitive driving circuit 23, and multiple data lines 202 are all connected with a letter Number processing circuit 25.Photosensitive driving circuit 23 is passed for providing corresponding scanning drive signal, and by corresponding scan line 201 It is defeated by corresponding photosensitive unit 22, to activate the photosensitive unit 22 to execute light sensing.The photosensitive driving circuit 23 is formed in substrate On 26, naturally it is also possible to be electrically connected by connector (for example, flexible circuit board) and photosensitive unit 22, i.e. connection multi-strip scanning Line 201.Signal processing circuit 25 receives corresponding photosensitive unit 22 by data line 202 and executes the telecommunications that light sensing generates Number, and obtain according to the electric signal biological information of target object.

In some embodiments, referring to figure 4., Fig. 4 shows the photosensitive unit 22 and scan line 201 of an embodiment With the connection structure of data line 202.The photosensitive unit 22 includes sensor devices 220 and switching device 222.The switching device 220 With a control terminal C and two signal ends, for example, the first signal end Sn1 and second signal end Sn2.Wherein, switching device 220 Control terminal C connect with scan line 201, the first signal end Sn1 of switching device 222 is through the connection of sensor devices 220 one with reference to believing Number L, the second signal end Sn2 of switching device 222 are connect with data line 202.

Specifically, above-mentioned sensor devices 220 are such as, but not limited to photodiode, phototriode, photodiode, light Resistance, thin film transistor (TFT) any one or it is several.It is negative by applying at the both ends of photodiode by taking photodiode as an example To voltage, at this point, if when photodiode receives optical signal the photoelectric current with optical signal proportion relation will be generated, The light signal strength received is bigger, and the photoelectric current of generation is then bigger, the speed of the voltage decline on photodiode cathode It is faster, therefore by the voltage signal on acquisition photodiode cathode, to obtain the reflection of target object different parts Light signal strength, and then obtain the biological information of target object.It is understood that in order to increase sensor devices 220 Multiple sensor devices 220 can be set in photosensitive effect.

Further, switching device 222 be such as, but not limited to triode, metal-oxide-semiconductor, in thin film transistor (TFT) any one or It is several.Certainly, which also may include other kinds of device, and quantity may be 2,3 etc..

By taking 22 structure of photosensitive unit shown in Fig. 4 as an example, the grid of thin film transistor (TFT) TFT is as switching device 222 The source electrode and drain electrode of control terminal C, thin film transistor (TFT) TFT are to the first signal end Sn1 and second signal that should be used as switching device 222 Hold Sn2.The grid of thin film transistor (TFT) TFT is connect with scan line 201, and the source electrode of thin film transistor (TFT) TFT is with photodiode D1's Cathode connection, the drain electrode of thin film transistor (TFT) TFT are connect with data line 202.The anode connection reference signal L of photodiode D1, Reference signal L is, for example, earth signal or negative voltage signal.

When above-mentioned photosensitive unit 22 executes light sensing, the grid by scan line 201 to thin film transistor (TFT) TFT applies one Driving signal, to drive thin film transistor (TFT) TFT to be connected.At this point, data line 202 connects a positive voltage signal, work as thin film transistor (TFT) After TFT conducting, the positive voltage signal on the data line 202 is applied to the cathode of photodiode D1 through thin film transistor (TFT) TFT, by In the plus earth of photodiode D1, therefore the both ends photodiode D1 will apply a backward voltage, so that photodiode D1 is in reverse bias, i.e., in running order.At this point, when there is optical signal to be irradiated to photodiode D1, two pole of photoelectricity The reverse current of pipe D1 increases rapidly, and so as to cause the curent change on photodiode D1, the electric current of the variation can be from number According to being obtained on line 202.Since the intensity of optical signal is bigger, the reverse current of generation is also bigger, therefore obtains according on data line 202 The current signal got can obtain the intensity of optical signal, and then obtain the biological information of target object.

In some embodiments, above-mentioned reference signal L can be positive voltage signal, negative voltage signal, earth signal etc..Only The electric signal provided on data line 202 and reference signal L is wanted to apply backward voltage to the both ends photodiode D1, to execute light Sensing, in the protection scope that the utility model limits.

It is understood that the connection type of thin film transistor (TFT) TFT and photodiode D1 is simultaneously in above-mentioned photosensitive unit 22 It is not limited to the connection type shown in Fig. 4, or other connection types.For example, as shown in figure 5, Fig. 5 shows another reality Apply the photosensitive unit 22 and scan line 201, the connection structure of data line 202 of mode.The grid G and scanning of thin film transistor (TFT) TFT Line 201 connects, and the drain D of thin film transistor (TFT) TFT is connect with the anode of photodiode D1, the source S of thin film transistor (TFT) TFT and Data line 202 connects.The cathode of photodiode D1 connects positive voltage signal.

In some embodiments, another implementation of the utility model is shown incorporated by reference to referring to Fig. 2-Fig. 4 and Fig. 6, Fig. 6 The partial structurtes of the display module of mode.Since photosensitive panel 200 is located at 100 top of display panel, photosensitive panel 200 has There is the first transmission region P1 that the optical signal for display panel 100 passes through, and the first transmission region P1 and display pixel 12 are right It should be arranged, not influence the normal display of display device.

Further, there is interval H between adjacent display pixel 12.Since photosensitive panel 200 is located at display panel 100 Top, therefore in order to not influence the display of display panel 100, photosensitive panel 200 is equipped with the first transmission region P1, first light transmission Region P1 is correspondingly arranged with display pixel 12, so that the optical signal that display panel 100 issues passes through.In some embodiments, In order to improve the display effect of display panel 100, the area of the first transmission region P1 is slightly larger than the area of display pixel 12.

In addition, due in substrate 26 scan line 201, data line 202, sensor devices 220 impermeable light characteristic, Er Qiewei It avoids optical signal from being irradiated to switching device 222 and influences the performance of switching device 222, therefore form scan line in substrate 26 201, the region of data line 202, sensor devices 220 and switching device 222 becomes the non-transparent region P2 of photosensitive panel 200.It should Non-transparent region P2 is located above the interval H of display panel 100.Correspondingly, switching device 222 and sensor devices 220 are located at non- Transmission region P2.It is understood that if the component being arranged on photosensitive panel 200 is able to achieve light transmission or is omitted certain impermeable The component of photo structure, then the non-transparent region P2 can also become the first transmission region P1.For example, in some embodiments, The scan line 201 and data line 202 can also be located at the first transmission region P1 by being made of transparent conductive material.Therefore, this reality With in novel embodiment, the not stringent restriction in the position and size of the first transmission region P1 and non-transparent region P2 can root It is adjusted flexibly according to actual conditions.

In some embodiments, the lower section in sensor devices 220 or switching device can be set in switching device 222 222 partly overlap setting with sensor devices 220.Scan line 201 and data line 202 also can be set in 222 lower section of switching device. So the setting of photosensitive unit 22, scan line 201 and data line 202 can be made more compact, and limited in setting area In the case where, increase the photosensitive area of sensor devices 220, to strengthen the sensing effect of photosensitive panel 200.

Specifically, in some embodiments, the semiconductor layer of the sensor devices 220 and top electrode also may extend into The top of switching device 222, to improve sensing area.By taking sensor devices 220 are photodiode as an example, the sun of photodiode Pole and semiconductor layer extend to the top of switching device 222, overlay switch device 222, and anode corresponds to the region of switching device 222 Light shield layer is further arranged in top, irradiates switching device 222 to prevent light.The cathode and switching device 222 of photodiode connect It connects.The cathode is lower electrode, such as is made of non-transparent conductive material, and the non-transparent conductive material is, for example, metal Material.

In some embodiments, by taking target object is the organism such as finger as an example, when finger in contact with or close to display mould When group 1, if there is ambient lighting to penetrate on finger, and finger has many institutional frameworks, such as epidermis, bone, meat, blood vessel etc., Therefore the part optical signals in environment light can penetrate finger, and part optical signals are then by finger.The optical signal for penetrating finger will Photosensitive unit 22 is reached, photosensitive unit 22 is not only sensed through the reflected optical signal of target object at this time, also senses ring Border light penetrates the optical signal of finger, so can not accurately be sensed.Therefore, in order to avoid environment shadow rings photosensitive unit 22 To the sensing of target object, Fig. 7 is please referred to, Fig. 7 shows the part knot of the photosensitive device of another embodiment of the utility model Structure.The photosensitive device 20 further comprises filter coating 29, and the filter coating 29 is arranged on the photosensitive panel 200, and corresponding Photosensitive unit 22 is arranged.The filter coating 29 is for the optical signal other than default wave band to be filtered.The utility model embodiment party Formula will reflect back into the optical signal come the optical signal preset other than wave band and filter out, to improve photosensitive by the filter coating 29 The sensing precision of device 20.

In some embodiments, presetting wave band is the corresponding wave band of blue light signal, i.e. filter coating 29 believes blue light Optical signal other than number filters out.

In some embodiments, presetting wave band is the corresponding wave band of green light signal, i.e. filter coating 29 believes green light Optical signal other than number filters out.

In the red light signal of environment light, blue light signal and green light signal, the target objects such as finger are to red The absorption of optical signal is most weak, followed by green light signal, most strong to the absorption of blue light signal.I.e. ambient lighting is penetrated in finger On, a large amount of blue light signal is only a small amount of by finger, penetrates finger even without blue light signal.Therefore, it selects Blue light signal or green light signal are filtered with the optical signal of wave section, can eliminate the interference of environment light significantly, are improved The sensing precision of photosensitive device 20.

It is equipped with interval H please continue to refer to Figure 11, between adjacent display pixel 12, and there is the second light transmission in the H of the interval Region.Sensor devices 220 in photosensitive unit 22 are correspondingly arranged in the lower section of the interval H between adjacent display pixel.Here Lower section be such as, but not limited to immediately below, can guarantee the position that enough optical signals are received.It is understood that if Optical signal across interval H is more, then the sensing precision of photosensitive device 20 is higher.In addition, sensor devices 220 can be according to reality Border situation and be selectively arranged, such as between red display pixel R and green display pixels G, blue display pixels B it is maximum Interval below be arranged sensor devices 220.

2, Figure 12 shows the relative position of sensor devices and display pixel in the photosensitive unit of an embodiment referring to Fig.1 Relationship, display pixel 12 is transparence display dot structure, and the display pixel 12 is such as, but not limited to red pixel R, green picture Tri- kinds of display pixels of plain G and blue pixel B.The sensor devices 220 of photosensitive unit 22 are correspondingly arranged in 12 lower section of display pixel.It needs It is noted that being correspondingly arranged for illustrating the positional relationship between sensor devices 220 and display pixel 12 here, not generation It must be provided with a sensor devices 220 below each display pixel 12 of table.

The utility model embodiment utilizes the translucency of display pixel 12, and reception is reflected and passed through through target object The optical signal of the display pixel carries out biological information sensing to target object.In addition, since the sensor devices 220 are arranged In 12 lower section of display pixel, therefore the photosurface of the sensor devices 220 can be equal to the area of display pixel 12, so using existing Some display panel structures can be realized, and reduce the preparation cost of display module 1, and guarantee the light across display pixel 12 The enough optical signals of signal mesopodium are received by sensor devices 220, improve the sensing precision of photosensitive device 20.

In some embodiments, the size and shape of photosensitive panel 200 is adapted to display panel, is so realized to contact Or close to the viewing area any position of display panel 100 target object predetermined biological information sensing.So, it changes Ground, in some embodiments, the photosensitive panel 200 are for example also smaller than display panel.In another example the photosensitive panel 200 sensing region also may be less than, be greater than or equal to display panel display area.

Further, display device is further used for executing touch-sensing, when the display device detects target object Touch or after, the display driver circuit drives the display pixel of corresponding touch area to shine.

Interference signal when further, in some embodiments, in order to solve to execute the sensing of biological information It influences, filter coating 29 is set on the photosensitive panel 200.It should be noted that since the photosensitive panel 200 is set to display panel 100 lower sections, therefore after the filter coating 29 can be independently arranged, then the mode for example, by pasting is set on photosensitive panel 200, So that the preparation process of filter coating 29 is simpler.

Accordingly, in some embodiments, Figure 13 is please referred to, the biological information method for sensing packet of the display module Include following steps:

S11, when a target object is in contact with or close to the display module and triggers biological information sensing, control is aobvious Show that the display pixel timesharing of panel is lighted, so that the optical signal that display pixel issues reaches target object；

S12, scanning drive signal is provided to multiple photosensitive units, be reflected back with driving photosensitive unit to receive through target object The optical signal come, and the optical signal received is converted into corresponding electric signal；

S13, the electric signal generated according to multiple photosensitive units, obtain the predetermined biological information of target object.

Specifically, independent control may be implemented in multiple display pixels 12 in display panel 100, by controlling single display When pixel 12 is lighted, point light source irradiation can be realized.When photosensitive unit 22 executes light sensing, only a display pixel 12 is issued Optical signal, thus it is less by the interference of the reflected optical signal of target object, to improve the sensing of photosensitive device 20 Precision.

In some embodiments, it when control 12 timesharing of display pixel is lighted, controls single display pixel 12 and lights, or At least two remote enough display pixels 12 of control predetermined space are lighted simultaneously, so that the light phase that target object is reflected back It mutually influences sufficiently small.

In some embodiments, photosensitive device structure as shown in connection with fig. 3, in above-mentioned steps S11, line by line or interlacing is mentioned For driving signal to multi-strip scanning line, to activate photosensitive unit 22.As shown in figure 3, for example, providing a scanning drive signal to the One scan line G1, remaining scan line do not provide scanning drive signal；After the predetermined time, provide the scanning drive signal to Article 2 scan line G2, remaining scan line do not provide scanning drive signal, and so on, until all scan lines 201 are equal It scans through.Certainly, however it is not limited to which this provides scanning drive signal line by line, can also provide scanning drive signal with interlacing.For example, mentioning First scan line G1 is given for a scanning drive signal, remaining scan line does not provide scanning drive signal；After the predetermined time, The scanning drive signal is provided and gives Article 3 scan line G3, remaining scan line does not provide scanning drive signal, and so on, directly It is scanned through to all scan lines 201.It should be noted that interlacing here is not limited every 1 row, it can also be every 2 rows, 3 Row etc..

In some embodiments, since photosensitive device 20 includes filter coating 29, it is assumed that the light letter that display panel 100 issues Number for white optical signal, then reflected optical signal is after the filtering of filter coating 29, and optical signal becomes weaker, photosensitive unit 22 almost sense less than can be increased aobvious by increasing the intensity of optical signal therefore when executing biological information sensing Show the luminous intensity of panel 100.

So, ground is changed, in some embodiments, drives display pixel timesharing when lighting in above-mentioned steps S11, it can be with Display pixel is driven to issue the optical signal of default wave band.Specifically, if such as filter coating 29 for will be other than blue light signal Optical signal is filtered, then the blue display pixels B of display panel 100 is driven to issue optical signal；It will be green if filter coating 29 is used for Optical signal other than coloured light signal is filtered, then the green display pixels G of display panel 100 is driven to issue signal.

The optical signal of wave band is preset by controlling the display panel 100 sendings, so that the optical signal warp that display panel 100 issues Crossing the filtering after target object reflects even across the filter coating 29 there will not be loss, that is, reach photosensitive unit 22 Optical signal will not have loss.In other words, if display panel 100 issue optical signal intensity increase how much, photosensitive unit 22 light signal strengths sensed can also increase accordingly how many.In this way, not only realizing the accurate sensing of optical signal, but also keep away The optical signal waste for having exempted from the sending of display panel 100, to reach energy saving purpose.

In present embodiment, in the biological information sensing of performance objective object, first determine target object photosensitive Touch area on panel 200 controls the display panel display pixel 12 corresponding with touch area in 100 according to the touch area Optical signal is issued, all display pixels 12 is avoided and issues optical signal, reach energy saving purpose；And according to touch area, Photosensitive panel 200 photosensitive unit 22 corresponding with touch area is driven to execute light sensing, so as to avoid entire photosensitive panel 200 Photosensitive unit 22 execute light sensing, accelerate sensed speed.

In some embodiments, it in conjunction with referring to Fig. 8 and Figure 12, is set since sensor devices 220 are corresponding with display pixel 12 Set, if therefore display pixel 12 when lighting, it is anti-that sensor devices 220 corresponding with the display pixel 12 not only sense target object It is emitted back towards the optical signal come, can also sense the optical signal of the sending of display pixel 12, thus the optical signal pair that display panel 100 issues The biological information sensing of target object interferes.Therefore, when executing biological information sensing, if sensor devices 220 are actuated to execute light sensing, then the corresponding display pixel 12 of sensor devices 220 is not lighted.

Please refer to Figure 15, Figure 15 show in the method for sensing of the another embodiment of the utility model display panel with it is photosensitive The working condition of panel, it should be noted that in the display panel illustrated in the distribution of display pixel and photosensitive panel The distribution of sensor devices is not limited thereto, and can also have other distributed architectures.By providing a scanning drive signal to one Scan line 201a, thus the work of sensor devices 220 that driving is connect with scan line 201a, and execute light sensing.At this point, should The display pixel 12b of 220 top of sensor devices is not lighted, for for passing through through the reflected optical signal of target object.In order to It realizes light sensing, then lights the display pixel 12 of a line near display pixel 12b, such as display pixel 12a.

In some embodiments, when control is lighted with display pixel 12b neighbouring display pixel 12a, control display picture Plain 12a timesharing is lighted.When being lighted by controlling 12 timesharing of display pixel, so that by the reflected optical signal of target object It interferes less, that is, interfering with each other for received optical signal between adjacent sensor devices 220 is avoided, to improve photoreceptor cartridge Set 20 sensing precision.
