In one embodiment, the passivation layer 4 shown in Fig. 1 is ideal situation, and its upper surface is more smooth.Actually
Because the thin film transistor (TFT) and photoelectric sensor of the lower section of passivation layer 4 relative to substrate are prominent, then the upper surface of passivation layer 4
Actual meeting is as shown in figure 4, be non-smooth.By further forming flatness layer 6 on passivation layer 4, it is ensured that overall structure
Upper surface it is more smooth, so as to thereon further formed other structures.
Alternatively, the photoelectric sensor include under it is at least one：
Photodiode, phototriode, phototransistor.
User can select photodiode and/or phototriode to sense as photoelectric sensor according to being actually needed
Fingerprint.
Fig. 5 is a kind of structural representation of display panel according to an exemplary embodiment.As shown in figure 5, wherein
The structure of thin film transistor (TFT) 2 and photoelectric sensor 3 is simplifiedly illustrated, alternatively, display panel, in addition to：
Color membrane substrates, it is oppositely arranged with the array base palte；
Wherein, black matrix 7 is provided with the color membrane substrates, the photoelectric sensor 3 is relative with the black matrix 7 to be set
Put；
Liquid crystal layer 8, it is arranged between the array base palte and the color membrane substrates.
In one embodiment, color membrane substrates are except including black matrix, in addition to the color blocking area being arranged between black matrix,
The color blocking material of respective color is filled in each color blocking area respectively, such as can include red color resistance area, green color blocking area and blueness
Color blocking area, it can also further include white color blocking area.
Fig. 6 is the structural representation of another display panel according to an exemplary embodiment.It is as shown in fig. 6, aobvious
Show that panel can include a plurality of data lines and a plurality of grid line, grid line and data wire, which intersect, defines multiple sub-pixels, word therein
Symbol R, G, B represent that sub-pixel corresponds to red, green, blue sub-pixel respectively.In the structure shown in Fig. 6, black matrix (not shown in Fig. 6)
The position that can be arranged on where data wire, grid line and/or thin film transistor (TFT).
And for one piece of color membrane substrates, wherein the distribution situation of each position black matrix is identical, although in the secondth area
Domain is not provided with thin film transistor (TFT), but in corresponding color membrane substrates, still can be provided with the color blocking such as red, green, blue area and black
Matrix, then photoelectric sensor (not shown in Fig. 6) can then set position corresponding with black matrix in the second area, so as to
So that photoelectric sensor is blocked by black matrix, to reduce the influence to display panel aperture opening ratio.
In one embodiment, due to second area not corresponding sub-pixel, therefore in color film base corresponding to second area
In plate, color blocking area and black matrix can also be not provided with, improves the brightness for the light that display panel is projected from second area, and then improve
The brightness of the light of photoelectric sensor is reflexed to, improves the precision of photoelectric sensor detection fingerprint.
Alternatively, the liquid crystal layer in the position corresponding to the second area without liquid crystal.
In one embodiment, due to setting first area of the second area of photoelectric sensor with setting thin film transistor (TFT)
Difference, if being provided with liquid crystal in position corresponding to second area, then the liquid crystal will not according to the unlatching of thin film transistor (TFT) or
Close and change deflection state, therefore the light that can not ensure to inject display panel second area from backlight module can be penetrated directly
Go out display panel, cause photoelectric sensor can not receive reflection light.
, can be in the filling liquid crystal into color membrane substrates and array base palte, not in corresponding second area based on above mentioned problem
Position filling liquid crystal, such as transparent resin can be set in the position of corresponding second area before filling liquid crystal so that
Display panel can be projected by transparent resin by obtaining from the light of backlight module injection display panel second area, and then ensure light
Electric transducer can receive light and arrive at after the hand of user the light reflected.
Alternatively, the liquid crystal layer is normal white mode in the position corresponding to the second area.
In one embodiment, due to setting first area of the second area of photoelectric sensor with setting thin film transistor (TFT)
Difference, namely thin film transistor (TFT) is not set in second area, if being provided with liquid crystal in position corresponding to second area, then
The liquid crystal will not change deflection state according to being turned on and off for thin film transistor (TFT), therefore can not ensure to penetrate from backlight module
Display panel can directly be projected by entering the light of display panel second area, cause photoelectric sensor can not receive reflected light
Line.
Based on above mentioned problem, the liquid crystal of second area correspondence position can be arranged to normal white mode (such as can pass through
The alignment films of adjustment second area liquid crystal layer both sides are realized), so as to inject the light of display panel second area from backlight module
Line, display panel always can be directly projected by the liquid crystal of the position, and then ensure that photoelectric sensor can receive light
The light reflected is arrived at after the hand of user.
Also, because the light of photoelectric sensor sensing is to inject display panel from light guide plate, and penetrated by display panel
To finger, then reflex to by finger the light of photoelectric sensor.And the electricity that photoelectric sensor generates for different colours photoinduction
Stream is different, therefore when from the mixed-color light of the just non-white light of display panel directive finger, by display panel
The light splitting effect of material, the color for the reflection light that photoelectric sensor different zones receive may be caused different, so that
Photoelectric sensor produces unstable electric current, influences testing result.
And by the way that the liquid crystal layer to be arranged to no liquid crystal in the position corresponding to the second area, or by the liquid crystal
Layer is arranged to normal white mode in the position corresponding to the second area, it is ensured that injects display panel second from backlight module
The light in region can all project display panel, and the light that display panel second area is injected from backlight module is generally white
Light, when from the just white light of display panel directive finger, the light splitting even across the material in display panel acts on, most Zhongdao
Light up to photoelectric sensor can still be mixed into white light, ensure the color for the reflection light that photoelectric sensor different zones receive
It is identical so that photoelectric sensor produces stable electric current, and then ensures testing result.
The disclosure also proposed a kind of display device, including above-mentioned display panel, in addition to：
Backlight module, it is arranged on side of the array base palte away from the color membrane substrates.
In one embodiment, backlight module can include light guide plate and be arranged on the lamp bar of light guide plate side, lamp bar hair
