Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.
In the mobile terminal, the front device comprises: light sensation (ambient light sensor + distance sensor). In order to increase the screen ratio of the mobile terminal, more and more manufacturers use the light-sensitive sensor under the screen at present. The light sensor under the screen is usually integrated with the ambient light sensor, and the basic working principle is as follows:
when the function of the distance sensor under the screen needs to be started, the light sensing device controls the laser lamp to emit laser pulse light (the laser lamp is selected to have strong anti-interference capability and stable light in the laser lamp), the laser can penetrate through gaps of RGB pixel points of the screen, the object is detected, the laser can be reflected by the object when the object is close to the mobile terminal, the emitted light can still be received by a photosensitive area of the light sensing device through the RGB gaps of the screen, a photoelectric conversion device of the light sensing device converts an optical signal into an electric signal, the object is judged to be effectively close to when the threshold value of the electric signal reaches a set threshold value, the closing information can be transmitted to the central processing unit to be processed, if the system can enter the screen closing operation under a conversation interface at the moment, if the pocket mode can prompt a user that the object is sheltered and is required to be timely removed.
When laser light emission laser ray, pass the diffraction phenomenon that can appear light from the gap, simultaneously because the luminous reason laser of screen and the visible light of screen RGB transmission take place interference phenomenon, can appear grey spot on the screen under diffraction phenomenon and interference phenomenon's effect, the number of grey spot is unanimous with the use number of laser light, this can lead to the user to see grey spot in the light sense region always when normal use, the most outstanding of performance under pure white interface especially, this can lead to very unpleasant of user experience sense, influence user experience.
In view of this, the present invention provides the following method for optimizing the light spot of the under-screen distance sensor, which substantially eliminates the influence of the gray light spot on the screen, thereby solving the above-mentioned problems.
In one embodiment, as shown in fig. 3, the present invention provides a method for spot optimization of an off-screen distance sensor, which is applied to a mobile terminal, where the mobile terminal includes a laser lamp; the method comprises the following steps:
s1, polishing the laser emitting port of the laser lamp to form a rough flower-shaped effect, so that laser pulse light rays emitted by the laser lamp form diffuse reflection at the laser emitting port, and the direct irradiation of the laser light rays in a direct irradiation area is optimized;
and S2, when the laser lamp emits laser pulse light, controlling the laser pulse light to pass through the gap of the screen RGB pixel point in the non-luminous time period of the screen RGB.
In the embodiment, the laser emitting port of the laser lamp is polished to form a rough flower-shaped effect, so that laser pulse light rays emitted by the laser lamp form diffuse reflection at the laser emitting port, and the direct irradiation of the laser light rays in a direct irradiation area is optimized, so that the laser pulse light rays at the boundary cannot appear in the direct irradiation area, and the problems of pattern occurrence at the boundary of gray spots and diffraction of the laser pulse light rays are optimized; through when laser lamp transmission laser pulse light, control laser pulse light passes from the gap of screen RGB pixel in the luminous period of screen RGB, makes laser pulse light staggers with the light that screen RGB pixel sent, thereby can avoid appearing the interference between the light that laser pulse light and screen RGB pixel sent, can realize under the screen light sense sensor and the screen distance sensor's application, can eliminate the influence of grey facula, optimize the screen and account for the ratio, realize the most probable screen and account for the ratio, realize the maximize of game interface, greatly promote user experience.
In one embodiment, in step S1, the laser emitting opening of the laser lamp is polished to form a rough frosted effect, so that pulsed laser light emitted from the laser lamp forms diffuse reflection at the laser emitting opening, and direct irradiation of the laser light in the direct irradiation area is optimized.
Specifically, since the emission of the laser pulse light is related to the shape of the opening of the laser emitting port, the laser pulse light in the region other than the opening position is blocked.
At present, a laser emitting port is not processed, laser pulse light rays can be directly emitted from the emitting port to a screen area to form diffraction, boundary light rays can appear in the direct emitting area, and therefore the problem of patterns can appear on the boundary of gray spots.
In this embodiment, in the design of laser lamp, polish at the laser emission mouth, form coarse mill flower form effect, form diffuse reflection in the trompil department of emission mouth when making laser pulse light knot jet out to form the optimization to the direct-emitting, laser pulse light line can disperse other regions of screen after shooting out from the laser lamp, and border light knot just can not appear in the region of directly shooting like this, thereby optimizes the problem that the pattern appears in the border of grey spot.
If form diffuse reflection and will form the optimization to penetrating directly when light jets out to light can disperse other regions of screen after the light jets out from the lamp, so need polish at the transmission mouth in the design of lamp, form coarse mill flower form effect, laser light forms diffuse reflection at the trompil department of lamp like this, and border light just can not penetrate the regional appearance again, thereby optimizes the marginal pattern problem that appears of grey spot.
In one embodiment, in step S2, when the laser lamp emits the laser pulse light, the laser pulse light is controlled to pass through the slits of the pixels of the screen RGB during the period when the screen RGB does not emit light.
Specifically, in order to solve interference of light emitted by the screen RGB, it is most desirable to control the laser pulse light to pass through a gap between pixels of the screen RGB in a period when the laser lamp emits the laser pulse light, and the emission is split emission. The shunt operation can be realized by testing the light-emitting time interval of the screen through special equipment.
As shown in fig. 4, when the laser lamp emits laser pulse light, the laser pulse light is controlled to pass through a gap between RGB pixels of the screen in a period when RGB of the screen does not emit light, and the method specifically includes:
and S21, automatically recognizing the refresh rate set by the system.
The refresh rate of the mobile terminal is 60HZ/90HZ/120HZ/144HZ/165HZ, when the user uses the mobile terminal, the system can automatically recognize the refresh rate after setting the required refresh rate in the system.
And S22, automatically calling the corresponding relation between the preset refresh rate and the screen RGB light-emitting time interval according to the refresh rate to obtain the screen RGB light-emitting time interval corresponding to the refresh rate.
Wherein, the corresponding relationship between the preset refresh rate and the screen RGB light-emitting time interval comprises: the light-emitting interval time of the corresponding screen is tested by special equipment according to different refresh rates, and the corresponding relation between the tested different refresh rates and the light-emitting interval time of the screen is preset in the system.
The mobile terminal needs to distinguish the refresh rate during the drive design, and the time for switching the screen pictures with different refresh rates is inconsistent, so the light-emitting interval time needs to be measured for different refresh rates.
After the system automatically identifies the refresh rate, the system automatically calls the corresponding relation between the preset refresh rate and the screen RGB light-emitting time interval to obtain the screen RGB on/off interval time, namely the screen RGB light-emitting time interval.
And S23, controlling the laser lamp to emit laser pulse light to pass through the gaps of the RGB pixel points of the screen in the non-luminous time interval of the RGB screen according to the obtained luminous time interval of the RGB screen.
In this embodiment, when the user uses the mobile terminal, after the system sets the required refresh rate, the system automatically calls the corresponding relationship between the preset refresh rate and the screen RGB lighting time interval after automatically recognizing the refresh rate, and obtains the screen RGB lighting/lighting interval time (screen RGB lighting time interval), so as to intelligently select the matched screen RGB lighting time interval parameters according to the refresh rate, so that the laser pulse light line emitted by the laser lamp reaches the optimal state, that is, the laser pulse light emitted by the laser lamp can pass through the gap of the screen RGB pixel point in the non-lighting period of the screen RGB, thereby solving the interference of the screen RGB light emitted.
In one embodiment, as shown in fig. 5, the method further comprises: and S3, increasing the emission frequency of the laser pulse light emitted by the laser lamp, and adjusting the emission time to a preset emission time and the waiting time to a preset waiting time.

In one embodiment, as shown in fig. 5, the method further comprises: and S4, setting the emission port of the laser lamp to be a porous design so as to disperse the energy of the laser pulse light.
Specifically, since the more concentrated the energy of the laser, the easier the gray spot effect is to be formed, the design of the laser lamp is modified from a single-hole design to a multi-hole design (preferably, a three-hole design), so that the laser pulse light is emitted from the multiple holes of the laser lamp to disperse the energy of the laser, and the gray spot formed on the side of the screen is dispersed and thus cannot be visually determined.
In one embodiment, as shown in fig. 5, the method further comprises: and S5, attaching a filter right below the light sensing screen to filter the visible color wavelength.
Specifically, because laser pulse light can be discerned by people's eyes through diffraction and the visible light of interfering other colours when passing through the screen, and different mobile terminal uses the screen is different moreover, so, through laminating an optical filter under the light sense screen, the wavelength of the colour that the filtering can see solves grey facula's problem.
In this embodiment, by using one or more of the above diffuse reflection design, split emission, frequency boosting, porous design, and optical filter use optimization or simultaneous optimization, the application of the light sensor under the screen and the distance sensor under the screen can be realized, the influence of gray light spots can be eliminated, the screen occupation ratio is optimized, the maximum possible screen occupation ratio is realized, the maximization of the game interface is realized, and the user experience is greatly improved.
