Description
Technical Field
The invention relates to the technical field of eyesight protection of mobile terminals, in particular to an eyesight protection device for a mobile terminal, a control method and a control device.
Background
With the popularization of mobile terminal electronic devices such as mobile phones and tablets, more and more people suffer from eye discomfort symptoms such as asthenopia, eye irritation, red eyes, blurred vision and the like. Referring to fig. 1, one important cause of these symptoms is that the user uses the electronic device 1' in such an environment for a long time: the screen brightness of the electronic device 1 'is higher than the background brightness of the electronic device 1' so that a bright area is formed on the screen side of the electronic device 1 'but a dark area is formed on the back side of the electronic device 1', which causes an inconsistency between the screen brightness and the background brightness of the electronic device. Under the environment, the pupil size adjusted by the eyes of the user according to the background environment is not adaptive to the brightness of the display screen, so that the user can easily feel visual fatigue after staring at the display screen for a long time to read, and the visual health is influenced.
Taking a mobile phone as an example, the mobile phone is an intelligent mobile terminal, and integrates a plurality of sensors and light-emitting elements in addition to a display screen, wherein the sensors include a light sensor arranged near a front receiver of the mobile phone and a flash lamp arranged on the back of the mobile phone. In the existing scheme for preliminarily solving the problem of inconsistent brightness of the screen and the background, the brightness of the surrounding environment is monitored by using a light sensor arranged near a receiver, and then the brightness of the screen is automatically adjusted according to a detection value. However, this solution also causes visual fatigue when the screen brightness is adjusted to be close to the limit value, and when the light sensor is used in a dark environment, the light sensor receives light reflected by the face of the user from the display screen, and therefore the brightness of the background environment cannot be accurately reflected, so that it is difficult to accurately coordinate the brightness between the screen and the background.
In a further solution: to light sensor, adopted a plurality of sensors to come the response environment light intensity, this one side can increase the hardware cost obviously, and on the other hand, arranging of a plurality of sensors can occupy great space, and the user of not being convenient for holds, just shelters from because of user's hand easily and leads to erroneous judgement environment light intensity. Aiming at the supplement of the ambient light, a flash lamp arranged on the back of the mobile phone is also superposed and utilized, namely, the flash lamp is automatically turned on according to the detection value of the brightness of the surrounding environment to supplement light and coordinate the brightness between the screen and the background. However, the general purpose of the flash lamp is to supplement light by using a flashlight or a photo, which is mainly suitable for illuminating objects at medium and long distances and is fixedly arranged at the edge or the corner of the back of the mobile phone, so that on one hand, the light supplement is not uniform from left to right, and on the other hand, if no proper reflecting surface is provided, the light supplement intensity is easily too high or too low, and therefore, the light supplement by using the flash lamp inherent to the mobile phone to coordinate the brightness of the screen still cannot fully guarantee the visual health of the user.
In addition, the market of mobile phones is very competitive, and there are many severe design requirements for mobile phones in order to maintain competitiveness, such as thickness of mobile phones, weight of mobile phones, and drop resistance, which are related to portability, and also very limited design space inside mobile phones in order to improve endurance.
Therefore, how to provide such a technical solution is still a challenge with high difficulty: the method is suitable for various mobile phones and improves the visual health of users when the mobile phones are used in dim light environment on the premise of not obviously damaging the original performance of the mobile phones.

The control method of the eyesight protection device disclosed by the embodiment comprises the following steps:
in step S100, the current ambient light brightness collected by the photosensitive element 20 is obtained, where the photosensitive element 20 is located in a photosensitive hole groove in the middle area of the casing 10, and the hole groove may be a hole or a groove. Referring to fig. 3, the casing 10 is integrally sheet-shaped and is used for being attached to the back of the mobile terminal (which may be the back of the mobile terminal itself, or the back of a mobile terminal protective case, etc.); the middle region of the housing 10 is provided with a photosensitive hole slot, the photosensitive element 20 is located in the photosensitive hole slot, and the photosensitive surface faces the outside of the housing 10, so that the light of the light-emitting element 30 can be prevented from directly irradiating the photosensitive element 20, that is, the accuracy of detecting the ambient light by the photosensitive element 20 is improved. The ambient light is not required to be collected from different angles by the multiple photosensitive elements 20, and is calculated based on data from different angles, and the current ambient light brightness obtained by the embodiment can reduce the calculation complexity.
Step S200, determining whether the current ambient light brightness is less than a first threshold. In a specific embodiment, the first threshold and the second threshold form a threshold interval, the first threshold is smaller than the second threshold, the first threshold may be, for example, 5lx, and the second threshold may be, for example, 7lx, that is, the threshold interval is, for example, 5-7lx, it should be noted that, in a specific implementation process, the first threshold and the second threshold may also be determined empirically or dynamically adjusted, for example, the threshold interval may also be 4-6lx, 5-8lx, 4-8lx, and the like. In this embodiment, if the current ambient light brightness is smaller than the first threshold, step S300 and step S400 are executed.
Step S300, outputting an ambient light control signal to the plurality of light emitting elements 30 to drive a plurality of light emitting elements 30 of the plurality of light emitting elements 30 to emit light and/or change brightness to provide ambient light with a preset brightness, so that the current ambient light brightness matches with a predetermined mobile terminal screen brightness. The predetermined mobile terminal screen brightness may be the lowest value of the mobile phone screen brightness, or may be other suitable brightness values, such as a value most comfortable for human eyes, like a brightness value similar to an electronic book screen, and so on. In this embodiment, the light emitting elements 30 are driven to emit light, so that the mobile terminal can be provided with ambient light with preset brightness, wherein the light emitting elements 30 are respectively located at the periphery of the light sensing element 20, and the light emitting surface faces the outer side of the housing 10. In a preferred embodiment, the plurality of light emitting elements 30 are located on respective sides of the housing 10, such as on opposite sides or sides of a square housing, and further such as on the sides of a circular housing near the outer edge. In a specific embodiment, some of the light emitting elements 30 may be driven to emit light, or all of the light emitting elements 30 may be driven to emit light; the light emitting elements driven to emit light may have the same or different emission luminance. In the specific implementation process, the preset brightness can be fixed or dynamically adjusted. To the preset luminance of dynamic adjustment, can set up through the user and preset luminance, also can follow the high in the clouds and acquire and preset luminance, specifically, acquire through the supporting APP of mobile terminal and preset luminance to this preset luminance data send for control circuit board. For the embodiment adopting dynamic adjustment of the preset brightness, the preset brightness can be generated according to different environments, and the preset brightness is prevented from being too bright or too dark. For example, in an open environment, the preset brightness may be brighter, and in a smaller environment, the preset brightness may be darker.

It should be noted that, in an implementation process, steps S630 and S730 may be performed by the same action, that is, after the current ambient light level is obtained, the current ambient light level may be compared with the first threshold and the second threshold, respectively. Of course, the current ambient light brightness may also be compared with the first threshold first, and if the current ambient light brightness is greater than the first threshold, the current ambient light brightness may be compared with the second threshold first; conversely, the current ambient light brightness may be compared with the second threshold first, and if the current ambient light brightness is smaller than the second threshold, the current ambient light brightness may be compared with the first threshold first.
Step S740 is to output the ambient light down control signal to the plurality of light emitting elements 30 to down-regulate the light emitting brightness of the plurality of light emitting elements 30.
