Description

Electronic device for preventing myopia by adjusting display wavelength range over time and method using the same

[0001] The present disclosure relates to an electronic device that prevents myopia by adjusting the display wavelength range over time, and a method using the same. More specifically, the present disclosure relates to an electronic device that adaptively adjusts the display wavelength range of the electronic device based on the external environment in which the user carrying the electronic device is located, and a display control method using the same.

[0002] Myopia is an eye condition that limits the ability to see objects that are close at hand. People with myopia must wear contact lenses or glasses to overcome the condition. Recently, the frequency of using various electronic devices with displays, including smartphones and tablets, close to the eyes has increased. Consequently, not only adults but also young children are being exposed to this condition more frequently than ever before.

[0003] Exposure to specific wavelengths of sunlight can significantly contribute to myopia. Furthermore, indiscriminate exposure to wavelengths from artificially generated light, such as those emitted by electronic devices, can exacerbate myopia. Adjusting the wavelengths of electronic device displays to suit the user's environment can prevent myopia. In other words, adjusting the wavelengths of light emitted from electronic devices, which are frequently exposed to the external environment, based on day and night, can help prevent myopia by aligning with one's circadian rhythm.

[0004] Accordingly, there is a growing need to adaptively judge what kind of light is being irradiated in the external environment of a person looking at an electronic device and adjust the wavelength range displayed on the display portion of the electronic device to prevent myopia.

[0005] The embodiment of the present disclosure has been proposed to solve the above-described problem, and unlike existing blue light blocking filters, it can adaptively adjust the wavelength range of the display unit according to the external environment to provide a more comfortable environment to the user.

[0006] Existing blue light blocking filters uniformly block the wavelength range corresponding to blue light regardless of day or night, thereby changing the color itself displayed through the display, causing inconvenience to users.

[0007] In contrast, the present disclosure adaptively adjusts the wavelength range of light displayed on the display unit according to the user's biological rhythm by identifying the main wavelength range of light incident during the day and night and / or the main wavelength range of light incident from the external environment, thereby reducing user discomfort and preventing and / or alleviating myopia. In addition, the present disclosure can prevent myopia without changing the color by adjusting the intensity of each sub-LED of the RGB LED on a pixel basis.

[0008] The problems to be solved by the present disclosure are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0009] In order to achieve the above-described technical problem, an electronic device according to the present disclosure detects a wavelength range of light in an external environment and adaptively adjusts a wavelength range of a display unit to provide myopia prevention includes a camera; a display unit; and a processor electrically connected to the camera and the display unit to control operations, wherein the processor may be configured to check a wavelength range for at least a portion of the display unit, detect information related to an external environment of the electronic device through the camera, and control a wavelength range for at least a portion of the display unit based on the information related to the external environment to adjust a wavelength range provided to a user of the electronic device through at least a portion of the display unit.

[0010] In addition, a display control method for detecting a wavelength range of light in an external environment and adaptively adjusting a wavelength range of a display unit to prevent myopia according to the present disclosure for achieving the above-described technical task may include a step of confirming a wavelength range for at least a portion of the display unit; a step of detecting information related to an external environment of an electronic device through a camera; and a step of controlling a wavelength range for at least a portion of the display unit based on the information related to the external environment to adjust a wavelength range provided to a user of the electronic device through at least a portion of the display unit.

[0011] According to the aforementioned problem solving means of the present disclosure, an electronic device that detects the main wavelength range of light incident from an external environment and provides myopia prevention can adaptively adjust and provide the wavelength range of light expressed through a display unit to a user carrying the electronic device.

[0012] For example, in an external environment where natural light mainly exists during the daytime, the electronic device of the present disclosure can control the wavelength range of light of the display unit to a wavelength range corresponding to blue light.

[0013] For another example, in an external environment where natural light mainly exists at night, the electronic device of the present disclosure can control the wavelength range of light of the display unit to a wavelength range corresponding to red light.

[0014] That is, according to the problem solving means of the present disclosure, the wavelength range of light during the day and at night, or in any external environment that the user is in, can be identified, and the wavelength range expressed through the display unit can be provided as a wavelength range that can prevent myopia in a user who is looking at the display unit in accordance with the user's biological rhythm.

[0015] Through this, the user can view the display portion of the electronic device in a comfortable environment that can alleviate or prevent myopia by adjusting the wavelength range of light supplied from the external environment to match the biological rhythm.

[0016] In addition, according to various embodiments of the present disclosure, an environment of a display unit can be provided that can alleviate or prevent myopia of a user by considering not only the external environment of natural light, such as day or night, but also the wavelength range of artificial light.

[0017] In addition, according to various embodiments of the present disclosure, when the wavelength range of light in the ultraviolet region is more dominant than a preset amount, a separate warning message is sent to the user to enable the user to move away from the electronic device, thereby preventing myopia.

[0018] The effects of the present disclosure are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description below.

[0046] The processor (110) can control one or more of the components discussed above in combination to implement various embodiments according to the present disclosure described in FIGS. 2 to 9 below in an electronic device (100).

[0047] The camera (120) according to the embodiment may include a hyperspectral camera.

[0050] The memory (140) according to the embodiment can store data supporting various functions of the electronic device (100), a program for the operation of the processor (110), can store input / output data (e.g., images, videos, etc.), and can store a plurality of application programs (or applications) running on the electronic device (100), data for the operation of the electronic device (100), and commands. At least some of these application programs can be downloaded from an external server via wireless communication.

[0051] The memory (140) may include at least one type of storage medium among a flash memory type, a hard disk type, an SSD (Solid State Disk type), an SDD (Silicon Disk Drive type), a multimedia card micro type, a card type memory (e.g., SD or XD memory, etc.), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk. In addition, the memory may be a database that is separate from the electronic device (100) but is connected by wire or wirelessly.

Furthermore, it will be readily apparent to those skilled in the art that the relative positions of the components may be altered to correspond to the performance or structure of the device.

[0057] Meanwhile, each component illustrated in FIG. 1 refers to software and / or hardware components such as a Field Programmable Gate Array (FPGA) and an Application Specific Integrated Circuit (ASIC).

[0058] FIG. 2 is a schematic flowchart of a display control method for providing myopia prevention according to various embodiments of the present disclosure.

[0059] Referring to FIG. 2, in step S210, a processor (e.g., processor (110) of FIG. 1) can check the wavelength range of a display unit (e.g., display unit (130) of FIG. 1). The processor can check the wavelength range of at least a portion of the display unit. For example, the processor can check whether the wavelength range of light expressed through the display unit is different for each individual area of ​​the display unit.

[0060] A processor according to an embodiment can identify a wavelength range of light being expressed in an individual region (e.g., a contour) of a display unit. For example, the processor can identify that a first wavelength range is provided to a first contour of the display unit. For another example, the processor can identify that a second wavelength range is provided to a second contour of the display unit. For yet another example, the processor can identify that the first wavelength range is provided to the entire region of the display unit. That is, the processor can identify a wavelength range of a screen provided to a user through a display unit of an electronic device (e.g., the electronic device (100) of FIG. 1).

[0061] In step S220, the processor may detect information related to the external environment of the electronic device via a camera (e.g., camera (120) of FIG. 1 ). The information related to the external environment may be information related to the environment at the location of the user owning the electronic device. For example, the processor may detect information related to the external environment as corresponding to wavelength information of light corresponding to daytime. For another example, the processor may detect information related to the external environment as corresponding to wavelength information of light corresponding to nighttime.

[0062] Specifically, the processor can detect information related to the external environment by analyzing the wavelength range of light incident through the camera. For example, the processor can determine that the external environment is daytime based on the wavelength range of light incident through the camera from the external environment (e.g., based on the wavelength range of light incident by daytime sunlight). For another example, the processor can determine that the external environment is nighttime based on the wavelength range of light incident through the camera from the external environment. That is, the processor can determine the wavelength range of light incident through the camera based on day and night stored in the memory or preset wavelength ranges of light, and match the information related to the external environment. The processor can control the wavelength range to be provided to the user through the display unit based on the matched information related to the external environment. In this way, the processor controlling the wavelength range provided through the display unit can reduce eye fatigue by alleviating (or preventing) myopia according to the wavelength range of the external environment to prevent myopia in the user.

[0063] In step S230, the processor can control the wavelength range of at least a portion of the display unit based on information related to the external environment. The processor can adjust the wavelength of light displayed on at least a portion of the display unit.

[0064] A processor according to an embodiment analyzes a wavelength range of light incident through a camera and detects information related to the external environment based on the analysis result. The processor can adjust the wavelength of light displayed on the display unit according to a wavelength range that matches the information related to the external environment. For example, if the information related to the external environment is detected as a wavelength of light mainly incident during the day, the processor can provide a screen on the display unit in a wavelength range expressed as blue light (e.g., a first wavelength range). For another example, if the information related to the external environment is detected as a wavelength of light mainly incident at night, the processor can provide a screen on the display unit in a wavelength range expressed as red light (e.g., a second wavelength range). Furthermore, even if the information related to the external environment is not day or night (e.g., not a natural external environment), the processor can detect a wavelength range of light in an artificially provided external environment and control the display unit according to a wavelength range that matches therewith. The matching here may be information matched to a wavelength range that can prevent the worsening of myopia or myopia itself in a user based on the information related to the external environment.

[0065] FIG. 3 is a schematic flowchart of a pixel-by-pixel LED control method according to various embodiments of the present disclosure.

[0066] In step S310, a processor (e.g., processor (110) of FIG. 1) can specify an outline by dividing at least a portion of a display unit (e.g., display unit (120) of FIG. 1) into pixel units. Here, the outline may be a certain area of ​​the display unit, and may be an area that is distinguished as having a certain wavelength range.

[0067] According to an embodiment, the processor can specify the entire display unit as a single outline. For example, the processor can adjust the wavelength range to be expressed within the outline by adjusting the wavelength range of the RGB LED provided to the display unit. When specifying the outline, the processor can set the outline so that the wavelength range expressed within the outline is constant. That is, the wavelength range expressed within the outline is the same wavelength range. For example, the wavelength range expressed within a first outline is the same as the first wavelength range. For another example, the wavelength range expressed within a second outline is the same as the second wavelength range.

[0068] In step S320, the processor can adjust the LED corresponding to the wavelength range to be expressed within the outline. The processor can adjust the wavelength range expressed on the display unit through the RGB LEDs present within the outline. In other words, the processor can adjust the wavelength range expressed within the outline of the display unit through the RGB LEDs within the outline.

[0069] FIG. 4 is an exemplary diagram of a pixel-by-pixel LED control method according to various embodiments of the present disclosure.

[0070] Referring to FIG. 4, a processor (e.g., processor (110) of FIG. 1) can control a wavelength range to be expressed within a first contour (410) and a second contour (420) corresponding to at least a portion of a display unit (e.g., display unit (120) of FIG. 1).

[0071] According to an embodiment, a processor can control an RGB LED through a sub-LED corresponding to a wavelength range to be expressed within an outline. For example, a display unit may be composed of multiple RGB LEDs. In this case, one RGB LED may be composed of sub-LEDs corresponding to each of the RGB colors. The processor can control the wavelength range of the RGB LED through the sub-LEDs.

[0072] For example, the processor may control the sub-LED corresponding to B among the sub-LEDs to emit light at a proportion of 50% and the remaining sub-LEDs corresponding to R and G at a proportion of 25% each in order to express the first wavelength range within the first outline (410). That is, the processor may control the emission ratio or proportion of each element constituting the sub-LED to express the first wavelength range corresponding to the wavelength range of blue light. For another example, the processor may control the sub-LED corresponding to R among the sub-LEDs to emit light at a proportion of 50% and the remaining sub-LEDs corresponding to G and B at a proportion of 25% each in order to express the second wavelength range within the second outline (420).

[0073] In this way, the processor can adjust the wavelength range to which the user's eyes are exposed by strengthening or weakening each of the R, G, and B pixels of the sub-LED of the electronic device (e.g., the electronic device (100) of FIG. 1) by the same ratio as the wavelength range to be expressed through the display unit. Through this, the user can comfortably be exposed to the screen without knowing that the wavelength range expressed through the display unit is being adjusted. This can be more efficient than the existing filter method of completely blocking the sub-LED of a certain wavelength range.

[0074] According to an embodiment, a processor can identify a display focusing area based on the movement of the user's pupil through a separate sensing unit (not shown). Specifically, the processor can sense the movement of the user's eyes, similar to eye tracking, to identify which area of ​​the display (e.g., a first contour (410), a second contour (420)) the user is currently viewing. Accordingly, the processor can adjust the wavelength range based on information related to the external environment only for the area the user is viewing on the display. Through this, the processor can minimize power consumption for adjusting the wavelength range of at least a portion of the display in an electronic device.

[0075] FIG. 5 is a flowchart of a display control method corresponding to information related to an external environment according to various embodiments of the present disclosure.

[0076] In step S510, a processor (e.g., processor (110) of FIG. 1) can check whether information related to the external environment corresponds to first information.

[0077] A processor according to an embodiment may determine a wavelength range of light entering through a camera (e.g., camera (120) of FIG. 1) from an external environment of an electronic device (e.g., electronic device (100) of FIG. 1). In this case, the processor may check matching information (e.g., first information, second information, etc.) stored in a memory (e.g., memory (140) of FIG. 1). That is, the matching information may be information obtained by dividing information related to the external environment according to the wavelength range of light entering through the camera from the external environment and matching it. For example, the first information may be information that the wavelength range of light entering through the camera from the external environment matches the wavelength range supplied from sunlight during the day. For another example, the second information may be information that the wavelength range of light entering through the camera from the external environment matches the wavelength range supplied from sunlight at night.

[0078] According to an embodiment, the processor can determine the wavelength range of light entering the camera, including natural light such as sunlight, as well as artificial light such as incandescent or fluorescent lights. In other words, the processor can not only match information related to the external environment to two pieces of information, but also fine-tune and match a wider range of wavelength ranges, thereby controlling the wavelength range provided through the display unit.

[0079] In step S520, if the information related to the external environment in S510 corresponds to the first information, the processor may control at least a portion of the display unit to a first wavelength range. Here, the first wavelength range may be a wavelength range of 400 nm or more and less than 450 nm. The first wavelength range may be a wavelength range of light supplied through sunlight during the day, which may alleviate or prevent myopia when the user's eyes look at the display unit. The first wavelength range may include a wavelength range of blue light.

[0080] In step S530, the processor can determine whether information related to the external environment corresponds to the second information. If the information related to the external environment corresponds to the second information in step S530, the processor can branch to step S540 to control at least a portion of the display unit to a second wavelength range. Here, the second wavelength range may be a wavelength range of 600 nm or more and less than 650 nm. The second wavelength range may be a wavelength range of light supplied through sunlight at night, which can alleviate or prevent myopia when the user's eyes look at the display unit. The second wavelength range may include a wavelength range of red light.

[0081] FIG. 6 is a flowchart of a display control method corresponding to a user's biometric information according to various embodiments of the present disclosure.

[0082] Referring to FIG. 6, in step S610, a processor (e.g., processor (110) of FIG. 1) can check the user's biometric information from a memory (e.g., memory (140) of FIG. 1). The user's biometric information can be utilized for personalized myopia prevention. For example, the user's biometric information can include age, gender, vision, and medical history information. In particular, among the user's biometric information, vision information is utilized to more effectively prevent myopia in the wavelength range adjustment method of the display unit of the present disclosure. The processor can check whether the user is currently in a myopic state (e.g., the degree of current refractive error) from the memory.

[0083] In step S620, the processor may adjust the ratio of wavelength range control displayed on at least a portion of the display unit. For example, if the user has severe myopia (e.g., -6 diopters), the processor may increase the ratio of adjusting the display unit to the first wavelength range and the second wavelength range. In other words, the processor may increase the wavelength range adjustment time of the display unit or the intensity of adjusting to a specific wavelength range. For another example, if the user does not have myopia, the processor may decrease the ratio of adjusting the display unit to the first wavelength range and the second wavelength range. In this way, the processor may adaptively adjust the wavelength range adjustment time or intensity of the display unit based on the user's biometric information. This may be an example of the processor utilizing the user's biorhythm.

[0084] According to an embodiment, the processor can control at least a portion of the display unit to a second wavelength range for a preset period of time. Here, the preset period of time can be determined from a table stored in memory in response to the user's biometric information. The wavelength range including 400 nm may be a wavelength range that determines a person's day-night cycle. Cells within the human retina that regulate biorhythms in response to the wavelength range including 400 nm exist. Biorhythms regulate human hormone secretion, helping maintain overall health. This can regulate eye growth and prevent myopia. Similarly, the wavelength range including 600 nm can activate the secretion of melatonin in the human body, inducing sleep and suppressing myopia. In addition, the wavelength range including 600 nm can stimulate the mitochondria of retinal cells, thereby promoting the health of retinal cells. For example, exposing a person's eyes to light in a wavelength range including 600 nm (e.g., near-infrared wavelength range) for three minutes twice a day for one year can suppress myopia. That is, a processor can load data containing such experimental results in a table format into memory and display the second wavelength range to the user via a display.

[0085] FIG. 7 is a block diagram of a display control method of an electronic device including a hyperspectral camera according to various embodiments of the present disclosure. Referring to FIG. 7, a processor (e.g., processor (110) of FIG. 1 ) can determine a wavelength range of light entering the electronic device through a camera (e.g., camera (120) of FIG. 1 ).

[0086] According to an embodiment, a hyperspectral camera can divide the wavelength of light entering an electronic device (e.g., the electronic device (100) of FIG. 1) through a lens and distinguish it into wavelength ranges. The camera of the present disclosure (e.g., the camera (120) of FIG. 1) may be configured as a camera module. The camera of the present disclosure may include a hyperspectral camera at a location where the lenses are gathered. Through this, the processor can divide the wavelength of light entering through the hyperspectral camera into wavelength ranges and analyze them.

[0087] Referring to FIG. 7, the camera of the present disclosure can receive external light through a lens (710). The camera can analyze the incident light (720). Thereafter, the processor can analyze the wavelength spectrum of the analyzed light (730). The processor can distinguish and determine the wavelength range of the incident light (740).

[0088] For example, if the average wavelength of the external environment of the electronic device in the morning is 600 nm or more, the processor can adjust the wavelength range expressed through the display unit (e.g., the display unit (130) of FIG. 1) of the electronic device to a first wavelength range including 400 nm. At this time, the processor can increase the ratio of adjusting the display unit to the first wavelength range to 80% or more to awaken the user's biological rhythm. For another example, if the average wavelength of the external environment of the electronic device is less than 400 nm, the processor can adjust the wavelength range expressed through the display unit of the electronic device to a second wavelength range including 600 nm. At this time, the processor can increase the ratio of adjusting the display unit to the second wavelength range to 80% or more to awaken the user's biological rhythm. The processor can maintain the user's biological rhythm cycle more stably and efficiently by adjusting the wavelength range expressed through the display unit of the electronic device based on information related to the external environment of the electronic device.

[0089] FIG. 8 is a detailed flowchart of a display control method according to various embodiments of the present disclosure.

[0090] In step S810, a processor (e.g., processor (110) of FIG. 1) can check the wavelength range of light incident through a camera (e.g., camera (120) of FIG. 1). The processor can check the wavelength range of light incident through a camera including a hyperspectral camera as shown in FIG. 7.

[0091] In step S820, the processor can detect which wavelength range of the external environment is dominant, either the blue wavelength range or the red wavelength range, based on the wavelength range of light. For example, the processor can detect which wavelength range of the light incident from the external environment is the main wavelength range. At this time, the processor can detect a wavelength range that matches 50% or more with a wavelength range stored separately from a memory (e.g., memory (140) of FIG. 1) among the wavelength ranges of the incident light as the dominant wavelength range. The number 50% is merely an example, and this may be a number that can be determined as the dominant wavelength range when stored in the memory.

[0092] In step S830, if information related to the external environment corresponds to third information, the processor may provide a warning message (e.g., an alarm message) through a display unit (e.g., the display unit (130) of FIG. 1).

[0093] According to an embodiment, the memory may store a wavelength range including a wavelength less than 400 nm (e.g., an ultraviolet wavelength range) by matching it to the third information. The processor may provide an alarm message to the user when a dominant wavelength range among the wavelength ranges of light in the external environment analyzed by the hyperspectral camera corresponds to the third information. This may be to prevent harm to the user when exposed to the ultraviolet wavelength range for a long period of time. For example, the processor may provide an alarm message to the user by setting a threshold value of twice the average ultraviolet level. That is, when the ultraviolet wavelength range accounts for 20% or more of the wavelengths of light incident through the hyperspectral camera, the processor may provide a warning message to the user.

[0094] FIG. 9 is a detailed flowchart of a control method according to display outline segmentation according to various embodiments of the present disclosure.

[0095] In step S910, a processor (e.g., processor (110) of FIG. 1) may receive at least one image via a communication unit (e.g., communication unit (150) of FIG. 1). The at least one image may be a still image of a web page, an image corresponding to a frame of a video, an image of a gallery, etc.

[0096] A processor according to an embodiment may repeatedly learn an image stored or received in an electronic device (e.g., the electronic device (100) of FIG. 1). The processor may learn color information within the image through an artificial intelligence learning model. Here, the artificial intelligence learning model may be a model optimized for learning color information contained in at least one image. In other words, the processor may determine color information within an outline contained in at least one image.

[0097] In step S920, the processor can identify color information contained in at least one image. Even without the artificial intelligence learning model, the processor can identify color information contained in at least one image.

[0098] In step S930, the processor can control the RGB LED by segmenting the outline based on color information and information related to the external environment. The outline may be a first outline and a second outline, etc. The processor can control the RGB LED corresponding to the wavelength range to be expressed within the first outline and the second outline through the sub-LED.

[0099] According to an embodiment, when a processor receives an image as input, the processor can determine as many contours as possible that can be provided through a display unit in a first wavelength range and a second wavelength range. This may be capable of determining the contours by following the movement of the user's eyes. The processor can identify a contour that can prevent the worsening of the user's myopia by adjusting the wavelength range of the display unit among the color information included in at least one image. Accordingly, the processor can determine at least one wavelength range to be expressed within the contour corresponding to at least a portion of the display unit.

[0100] Meanwhile, the disclosed embodiments may be implemented in the form of a recording medium storing computer-executable instructions. The instructions may be stored in the form of program code, and when executed by a processor, may generate program modules to perform the operations of the disclosed embodiments. The recording medium may be implemented as a computer-readable recording medium.

[0101] Computer-readable storage media include all types of storage media that store instructions that can be deciphered by a computer. Examples include read-only memory (ROM), random access memory (RAM), magnetic tape, magnetic disks, flash memory, and optical data storage devices.

[0102] The disclosed embodiments have been described with reference to the attached drawings as described above. Those skilled in the art will understand that the present disclosure can be implemented in forms other than the disclosed embodiments without altering the technical spirit or essential features of the present disclosure. The disclosed embodiments are illustrative and should not be construed as limiting.
