The embodiment of the application provides a method for controlling fingerprints under a screen, which can be applied to a mobile phone, a tablet personal computer, a wearable device, a vehicle-mounted device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, a super-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA) and other display devices with an identification function of fingerprints under a screen, and can be specifically executed by a processor of the display device when a computer program is run. The display screen of the display device may be a liquid crystal display screen or an organic light-Emitting Diode (OLED) screen, and the display device may be a full-screen display device with an ultra-high screen ratio.
In application, for a display device using an organic electroluminescent display screen, in order to realize a function of identifying fingerprints under the organic electroluminescent display screen, a fingerprint identification module under the organic electroluminescent display screen needs to be additionally arranged in the organic electroluminescent display screen. The organic electroluminescent display panel itself emits visible light to normally display a picture. Visible light is received by the optical sensor of fingerprint identification module under the screen through the display panel after the finger surface reflection, because the valley ridge line of finger fingerprint is different to the reflectivity of invisible light for the last photon volume that different photosensitive regions received of optical sensor is different, after image algorithm handles, forms the alternate fingerprint image of light and shade, is used for realizing fingerprint unblock matching.
In application, for a display device using a liquid crystal display, the liquid crystal display is mainly composed of a display Panel (Panel) and a backlight module, and the backlight module is usually provided with a backlight film structure such as a brightness enhancement film, a diffusion film, a light guide film, a reflection film and a backlight lamp. In order to realize the function of identifying the fingerprint under the screen of the liquid crystal display screen, the liquid crystal display screen needs to be additionally provided with the fingerprint under the screen identification module, and the backlight module is internally provided with the visible light backlight and the invisible light backlight at the same time. After the visible light penetrates through the backlight film structure, the visible light is matched with the deflection of liquid crystal molecules in the display panel to normally display pictures on the display panel. The invisible light shines user's finger after seeing through the fingerprint identification region on backlight membrane structure and the display panel, sees through display panel and backlight membrane structure behind the finger surface reflection again and is received by the optical sensor of fingerprint identification module under the screen, because the valley ridge line of finger fingerprint is different to the reflectivity of invisible light for the last photon volume that different photosensitive regions received of optical sensor is different, after image algorithm handles, forms light and shade alternate fingerprint image, is used for realizing fingerprint unblock matching. Currently, infrared backlights are generally adopted in the industry as invisible backlights, specifically, infrared LEDs (Light Emitting diodes) with a wavelength of 850nm or 940nm can be adopted, and the photoelectric conversion efficiency of the optical sensor is the highest at the two wavelengths. Since the infrared LED having a wavelength of 850nm has a small amount of visible light having a wavelength of 780nm in its wavelength width, an infrared LED having a wavelength of 940nm is preferable as the invisible light backlight.

The display device is provided with a motion sensor, and the motion state of the display screen can be detected through the motion sensor. Motion sensors may include, but are not limited to, acceleration sensors, gyroscopes, gravity sensors, pedometers, and the like.
In application, when the display device detects that a user does not use the display device within a certain time, or detects that the user triggers the display device to enter a standby mode, the display device enters a full screen-off state to reduce power consumption. After entering the complete screen-off state, the display device can detect the motion state of the display screen through the motion sensor, and whether the fingerprint identification area is lightened or not is determined according to the motion state, so that a user can wake up the display device and lighten the display screen by touching or pressing the fingerprint identification area when the fingerprint identification area is lightened, and the display device is triggered to be switched from the standby mode to the working mode.
Step S302, if the motion state meets a preset condition, whether the display screen is shielded or not is detected.

The user can also edit at least one preset condition in a user-defined manner according to actual needs, and the user-defined editing operation of the user can include an adding and deleting and checking operation on at least one condition.
In application, the preset and stored conditions may include, but are not limited to:
1. the display screen has no shaking and starts shaking after the duration time is longer than the first time; the first time can be set by a user in a self-defined manner according to the use habit, for example, the first time can be set to any time from 1 second to 10 seconds, and specifically can be 3 seconds;
2. the display screen does not shake and starts to shake after the duration time is longer than the first time, and the orientation of the display screen is changed and faces upwards or is vertical to the ground; this condition applies to a scenario where the user uses the display device with the display screen facing up or perpendicular to the ground, e.g., the display screen is generally facing up or perpendicular to the ground when the user uses the display device in a sitting or standing position;
3. the display screen does not shake, shaking starts after the duration time is longer than the first time, and the orientation of the display screen changes and faces downwards; this condition applies to a scenario in which the user uses the display device with the display screen facing downward, for example, when the user uses the display device in a lying state, the display screen is usually facing downward.
In application, when the motion state meets the preset condition, the user can be preliminarily judged to need to use the display device at the moment, whether the user really needs to use the display device or not is further judged, whether the display screen is shielded or not is further detected, and when the display screen is not shielded, the user really needs to use the display device can be further judged.
In application, the display equipment is provided with the optical sensor, and whether the display screen is shielded or not can be detected through the optical sensor. The light sensor may include, but is not limited to, an ambient light sensor, a proximity sensor, and the like. The method is suitable for detecting whether the display screen is shielded or not under various scenes that a user places the display equipment in a pocket, holds the display equipment on a hand, places the display screen downwards on any table board and the like.
And S303, if the display screen is not shielded, controlling the fingerprint identification area of the display screen to be lightened.
In application, after the motion state of the display screen meets the preset condition, when the display screen is further detected to be not shielded, the fact that the user really needs to use the display equipment can be judged, the fingerprint identification area of the display screen can be controlled to be lightened at the moment, the user can see the fingerprint identification area, and therefore the display equipment is triggered to enter the working mode through touching or pressing the fingerprint identification area.
As shown in fig. 4, in one embodiment, before detecting the motion state of the display screen in step S301, the method includes:
step S401, after the display screen is switched to the standby mode, controlling a fingerprint identification area of the display screen to be lightened;
and S402, after the fingerprint identification area is lightened for the second time, controlling the fingerprint identification area to be extinguished and entering a complete screen-off state.
In application, when the display device is switched from the working mode to the standby mode, the display screen can be switched from the bright screen state to the complete holographic screen state, at the moment, the fingerprint identification area can be controlled to light for the second time in order to conveniently wake up the display device by a user, if the operation that the user touches or presses the wake-up display device of the fingerprint identification area is not detected within the second time, the fingerprint identification area is controlled to be turned off, so that the display device enters the complete screen-rest state, and the power consumption is saved. The second time can be set by a user according to the use habit, for example, the second time can be set to any time from 1 second to 10 seconds, and specifically can be 5 seconds.
In the application, in the second time after the fingerprint identification area is controlled to be lit in step S402, as long as the operation of the user touching or pressing the display device for waking up the fingerprint identification area is not detected, the fingerprint identification area is controlled to be turned off after the second time no matter what state the motion state of the display device is in at this time, so that the problem that the power consumption is high due to the fact that the fingerprint identification area is erroneously triggered to be lit when the display device is in the standby mode after the display device enters the standby mode and the display device is shaken when the user walks, runs or jolts on a vehicle along with the user can be effectively avoided, and the fingerprint identification area is not easily triggered to be lit by the erroneous operation, and the power consumption can be effectively reduced.
In one embodiment, step S401 includes:
and after the third time of switching to the standby mode, controlling the fingerprint identification area of the display screen to be lightened.
In application, when the display device is switched from the working mode to the standby mode, the display screen is switched from the bright screen state to the complete holographic screen state, and at this time, in order to reduce power consumption and facilitate a user to wake up the display device, the fingerprint identification area may be controlled to be lit up after the third time of switching to the standby mode (that is, after the third time of switching the display screen to the complete holographic screen state). The third time may be set according to actual needs, for example, may be set to any time from 0.5 seconds to 2 seconds, and specifically may be set to 1S.
As shown in fig. 5, in one embodiment, after detecting the motion state of the display screen in step S301, the method includes:
step S501, if the display screen does not shake and shakes after the duration time is less than or equal to the first time, the complete screen-resting state is maintained.
In application, the display screen does not shake and starts to shake after the duration is less than or equal to the first time, and the display screen starts to shake after no shaking (namely the duration of no shaking is greater than 0 and less than or equal to the first time) in a short time and continues to shake (namely the duration of no shaking is 0). After the display device enters the standby mode, if the display screen begins to shake after no shaking in a short time, or the display screen continuously shakes, the instruction display device shakes when the user walks, runs or jolts on a vehicle along with the user, and at this time, the display device is continuously kept in a complete screen resting state. So, can effectively avoid after display device gets into standby mode, display device is walked, is run or jolts and produce under the condition of rocking along with the user on the vehicle, and the fingerprint identification region is lighted in the mistake trigger, causes the higher problem of consumption to take place, makes the difficult easy wrong operation trigger of fingerprint identification region and lights, can effectively reduce the consumption.
As shown in fig. 6, in one embodiment, step S302 includes:
step S601, if the display screen does not shake and shakes after the duration time is longer than the first time, whether the display screen is shielded is detected.
In the application, after the display device enters the standby mode, if the display screen begins to shake after not shaking for a long time, the user can be preliminarily judged to pick up the display device and need to use the display device, whether the display screen needs to be further detected to be shielded or not in order to further judge whether the user really needs to use the display device or not, and when the display screen is not shielded, the user can be further judged to really need to use the display device.
In one embodiment, after step S302, the method includes:
and if the display screen is shielded, keeping the complete screen-turning state.
In the application, after the user needs to use the display device by preliminary judgment, the further detection that the display screen is shielded can not further judge that the user really needs to use the display device, at the moment, the user can be considered to place the display device in a pocket, hold the display device in the hand or place the display screen on any table board downwards, the user does not need to use the display device, the display device is continuously kept in a complete screen-rest state, the false triggering is avoided, and the power consumption is saved.
As shown in fig. 7, in one embodiment, step S303 includes:
step S701, if the display screen is not shielded, controlling a backlight lamp of a local area in a backlight module of the display screen to be lightened, providing a backlight source for the fingerprint identification area, and lightening the fingerprint identification area.
In application, for a display device adopting a liquid crystal display screen, all backlight lamps in a backlight module of the display device can be lightened to provide backlight sources for a fingerprint identification area, only the backlight lamps in a local area corresponding to the fingerprint identification area in the backlight module can be lightened, and the backlight sources are provided for the fingerprint identification area only through the backlight lamps in the local area, so that power consumption can be effectively received.
As shown in fig. 8, an exemplary optical path diagram of the liquid crystal display screen when only the local area backlight 121 of the backlight module 12 of the liquid crystal display screen is turned on to provide a backlight source for the fingerprint identification area 111 of the display panel 11 is shown.
