In one embodiment, because the light of photoelectric sensor sensing is to inject display panel from light guide plate, and pass through
Display panel directive finger, then reflex to by finger the light of photoelectric sensor.And photoelectric sensor is for different colours light sensation
The electric current that should be generated is different, therefore when from the mixed-color light of the just non-white light of display panel directive finger, by aobvious
Show the light splitting effect of the material in panel, the color for the reflection light that photoelectric sensor different zones receive may be caused not
Together, so that photoelectric sensor produces unstable electric current, testing result is influenceed.
And when from the just white light of display panel directive finger, the light splitting even across the material in display panel is made
With white light can be still mixed into by eventually arriving at the light of photoelectric sensor.When the just monochromatic light from display panel directive finger
When, light splitting effect can't occur in its communication process, the light for eventually arriving at photoelectric sensor still can be the monochromatic light.
So as to which control chip when receiving the control signal by adjusting data-signal, pixel electrode can be adjusted
Voltage, to change the degree of deflection of the liquid crystal of photoelectric sensor position so that the red sub-pixel of the position, green sub-pixels,
Blue subpixels are all turned on, and then can all be projected from the white light of backlight module injection display panel, and through display
Still it is white light after panel, and then the light by user's finger reflection is also white light, the light for inciding photoelectric sensor is also white
Light；Or make it that only monochrome sub-pixels are opened, such as red sub-pixel is opened, so as to which the white light in the only region can lead to
Cross, and white light passes through the optical filtering of red color resistance material, can only be left feux rouges injection, is monochromatic so as to project the light of display panel
Feux rouges, and then the light by user's finger reflection is also feux rouges, the light for inciding photoelectric sensor is also white light.

Transport to the touch module；
Wherein, the touch module is when the location sensitive of the corresponding photoelectric sensor is to touching signals, it is determined that described
Whether display device is in the state of fingerprint to be verified, if the state in fingerprint to be verified, institute is transmitted to the control chip
State the signal that photoelectric sensor is in the state of fingerprint to be identified.
Because photoelectric sensor is arranged in array base palte, and array base palte corresponds generally to effective display of display panel
Region, therefore user is when effective display area domain carries out the operation of non-fingerprint recognition, it is also possible to where clicking photoelectric sensor
Region, and in this case if control thin film transistor (TFT) corresponding with second area and light source are opened, then it can cause electricity
Waste.
In one embodiment, by further detecting the working condition of display device, photoelectricity can be clicked in user
During sensor correspondence position, determine whether display device is in the state of fingerprint to be verified, wherein fingerprint state to be verified can wrap
Screen lock state, checking fingerprint payment status etc. are included, and when display device is in the state, it may be determined that user clicks on photoelectric transfer
The operation of sensor correspondence position is to carry out fingerprint recognition, and then controls corresponding with second area thin film transistor (TFT) and light source to open again
Open, you can be effectively prevented from electricity and waste and switch loss caused by photoelectric sensor.
