Show the optical signal of pixel, biological information sensing is carried out to target object.Further, since the sensor devices 220 be arranged at it is aobvious
Show the lower section of pixel 12, therefore the photosurface of the sensor devices 220 can be equal to the area of display pixel 12, so using existing
Display panel structure can be achieved, and reduce the manufacturing cost of display module 1, and ensure the optical signal through display pixel 12
The enough optical signals of mesopodium are received by sensor devices 220, improve the sensing precision of photosensitive module 2.
Further, display panel 100 further includes the driver circuit (not shown) for driving each display pixel 12 luminous,
And display device further comprises display driver circuit (not shown), which can be arranged at each aobvious
Between showing pixel 12, each lower section of display pixel 12 can also be arranged at.Display driver circuit can be arranged at display panel 100
On, it can also be connected by flexible PCB with display pixel 12.The display driver circuit is used to drive multiple display pixels 12
Shine, light source during light sensing is carried out for use as the photosensitive module 2.
In some embodiments, sensor devices 220 are any one in red, blueness, green three kinds of display pixels
A or multiple lower section, by positioned at the lower section of display pixel 12, it is ensured that more optical signals are received by sensor devices 220.
Such as shown in Figure 15, which is located at below blue display pixels B.In addition, other optical signals in order to prevent is dry
Disturb, filter coating 29 can be set on sensor devices 220.The filter coating 29 is used to carry out the optical signal beyond default wave band
Filter.For example, if the optical signal beyond blue light signal is interference signal, blue filter film is set, by blue light signal
Optical signal beyond corresponding wave band is filtered.It should be noted that since the photosensitive panel 200 is arranged at display panel 100
Lower section, therefore after the filter coating 29 can be independently arranged, then fit on photosensitive panel 200, so that the system of filter coating 29
Standby technique is simpler.
In some embodiments, Figure 16 is refer to, Figure 16 shows the display module of another embodiment of the present invention
Part-structure.In the embodiment, the luminescent layer 103 of display pixel 12 sends white light, and the light of display pixel 12 is penetrated
Go out side and be equipped with CF films 13, which is used to be filtered the white light that display pixel 12 is sent, formed red, green and
Blue three kinds of optical signals.Specifically, which includes three kinds of photoresists, that is, corresponds to three kinds of display pixels and be arranged to red, green
Color, blue three kinds of photoresists, when the white light that luminescent layer 103 is sent passes through the CF films 13, red light signal, green are projected by corresponding
Optical signal, blue light signal.In other words, when the optical signal reflected through target object passes through display panel 100, red light
Signal can be filtered when passing through the blue light resistance of CF films 13 or green photoresist.Therefore, by sensor devices in photosensitive unit 22
220 are arranged at the underface of the corresponding display pixel of blue light resistance and/or the corresponding display pixel 12 of green photoresist, can eliminate dry
The influence of signal is disturbed, so as to improve the sensing precision of photosensitive module 2.

Lower section.Accordingly, sensor devices 220 are equipped with filter coating 29, the filter coating be used for by the optical signal beyond default wave band into
Row filtering, and the setting of the default wave band is with the different and different of the placement location of sensor devices 220.Specifically, if photoreceptor
Part 220 is arranged at below green display pixels G, then red and blue light signal in the optical signal reflected by target object
Green display pixels will be passed through, therefore the filter coating set is used to filter out the optical signal beyond blue light signal so that photosensitive
Device 220 only receives blue light signal.Similarly, if sensor devices 220 are arranged at red display pixel R, blue display pixels B
Lower section, then filter coating 29 is for the optical signal beyond green light signal to be filtered out so that sensor devices 220 only receive green light
Signal.
