[0042] The embodiments described below are exemplary only, and are intended to be illustrative of the application rather than limiting.

[0043] It should be noted that the embodiments described are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0044] The terms used in the embodiments of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the embodiments of the present application. The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0045] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0046] A far vision screen is a special screen that can help users perform eye exercises and visual protection by displaying specific images or text. The principle of the far vision screen is to stimulate the accommodation function of the eye and the visual nervous system by adjusting the size, clarity and contrast of the displayed image or text, so as to achieve the effect of preventing and controlling myopia. Using the far vision screen for eye exercises can effectively improve the accommodation ability of the eye, reduce eye fatigue and improve visual comfort. The use method of the far vision screen is generally to place it at an appropriate distance and height, and then perform eye exercises by watching the images or text on the screen. The specific exercise method can be selected according to the needs and suggestions of individuals, such as adjusting the focal length, eye movement, fixation point transformation, etc.

[0047] The imaging principle of the far-view screen is as shown in Figure 1A or Figure 1B .

[0048] Figure 1A A schematic diagram of a far-view screen provided in the related art is as shown in Figure 1A The far-view screen includes a built-in display screen, a planar beam splitter, and a total reflection freeform mirror. The eye can view a virtual image presented behind the far-view screen through the far-view screen. The distance d between the eye and the center of the built-in display screen is 30 cm, and the distance D between the eye and the virtual image presented behind the far-view screen is 500 cm. Because the theoretical data of the accommodation of the lens of the eye is 1 / 5 = 0.2D, the virtual long-distance view of the eye almost does not need to be accommodated by the lens, so that the display image of the far-view screen in the near distance is projected into a magnified virtual image at a distance of D = 500 cm through the optical reflection projection scheme, so that the user's eye can view the display image of the far-view screen at a long distance through the far-view screen, and the lens of the eye is relaxed.

[0049] Figure 1B A schematic diagram of another far-view screen provided in the related art is as shown in Figure 1B A point is the center of a concave mirror, a back concave mirror includes B point, D point, L point, K point and C point, a semi-transparent mirror includes E point, M point and F point, I point and J point represent images of patterns on a liquid crystal screen passing through the semi-transparent mirror, H point and G point represent patterns on a liquid crystal screen inside the far-view screen, and O point and N point represent a zoomed virtual image passing through the concave mirror.

[0050] The far-view screen in the related art displays a zoomed virtual image projected in the distance. When the display image of the far-view screen is dark, the zoomed virtual image projected in the distance of the far-view screen disappears, and the actual display content of the far-view screen in the near distance is easily observed by the eye, which causes the eye to need to frequently adjust the focus and increases visual fatigue.

[0051] To solve the technical problems in the related art, an embodiment of the present application provides an electronic device.

[0066] Based on the electronic device in Figure 2 , the display method of the display screen provided by the embodiments of the present application will be described in detail below. Figure 3 and Figure 4 The display method of the display screen provided by the embodiments of the present application will be described in detail below.

[0067] The electronic device obtains a first screen luminous intensity of the display screen. Specifically, the electronic device obtains an extra low voltage current (Elvss) of the display screen, where the Elvss is used to represent the first screen luminous intensity; or the electronic device obtains a gray scale and a screen backlight brightness information of each frame of the display screen, and generates the first screen luminous intensity according to the gray scale and the screen backlight brightness information; or the electronic device obtains the first screen luminous intensity through a screen luminous intensity sensor. The electronic device can obtain the Elvss of the display screen through a screen driving integrated circuit (IC).

[0068] The electronic device determines whether the first screen luminous intensity is less than a first set threshold. In an implementation of the embodiment, the electronic device can determine whether the Elvss is less than a current set threshold, and when the Elvss is less than the current set threshold, it is determined that the screen luminous intensity is less than the set threshold. The current set threshold can be set according to actual conditions, for example, when the screen of the electronic device is a liquid crystal display (LCD), the current set threshold is 20 mA. For another example, when the screen of the electronic device is an organic light-emitting diode (OLED), the current set threshold is 10 mA. In the embodiment, the first set threshold can be set according to actual conditions, for example, the first set threshold is 100 nit.

[0069] If the electronic device determines that the first screen luminous intensity is less than the first set threshold, the electronic device lights up a luminous mark of the display screen.

[0070] In the embodiment, the luminous mark can be a pattern displayed on the display screen, and correspondingly, lighting up the luminous mark of the display screen can be implemented by displaying a preset pattern on the display screen.

[0071] Figure 3 A display change diagram of the display screen is provided in the embodiment, when the first screen luminous intensity of the display screen is not less than the first set threshold, an interface displayed on the display screen and a virtual image presented behind the display screen are as shown in FIG. a Figure 3 As shown in FIG. a, the interface displays a plurality of application icons, and the luminous mark is not lit up

[0072] The number of the luminous mark can be multiple, for example, the shape of the luminous mark can be a cross, for example, the position of the luminous mark can be the periphery within the boundary of the display screen, for example, as shown in FIG. b Figure 3 As shown in FIG. b, a plurality of cross-shaped luminous marks are arranged on the periphery within the boundary of the display screen.

[0073] The luminance of each pixel in the preset pattern can be the same or different. For ease of processing, the luminance of each pixel in the preset pattern can be the same. The plurality of pixels can constitute a light-emitting marker. In an implementation of the present application, the electronic device can light up the light-emitting marker of the display screen to display according to the set marker light-emitting intensity. For example, the set marker light-emitting intensity is 60 nit. In another implementation of the present application, the electronic device can obtain the ambient light intensity through the ambient light sensor, determine the light-emitting marker luminance according to the ambient light intensity, and light up the light-emitting marker of the display screen according to the light-emitting marker luminance. The ambient light intensity is positively correlated with the light-emitting marker luminance, and the brighter the ambient light intensity, the higher the light-emitting marker luminance. Specifically, the ambient light intensity can be processed by interpolation lookup according to the corresponding relationship between the obtained ambient light intensity and the light-emitting marker luminance to generate the light-emitting marker luminance corresponding to the ambient light intensity.

[0074] The light-emitting marker can be a static marker or a dynamic marker.

[0075] The static marker refers to the position and luminance of the light-emitting marker on the display screen remaining unchanged. For example, the static marker is a cross-shaped light-emitting marker with a luminance of 60 nit in the periphery of the display screen boundary.

[0076] The dynamic marker refers to the position and / or luminance of the pattern being changeable. For example, the dynamic marker can be a moving cross-shaped marker according to a set trajectory and a set moving speed. The set trajectory and the set moving speed can be set according to actual conditions. For example, the set trajectory is a clockwise trajectory along the periphery of the display screen boundary, and the set moving speed includes a set moving angular speed of 2 rad / s and a set moving linear speed of 1 m / s. For example, as shown in FIG. 2, a plurality of cross-shaped light-emitting markers arranged in the periphery of the display screen boundary are displayed according to the clockwise trajectory along the periphery of the display screen boundary. Figure 3

[0077] In some embodiments, light-emitting devices, for example, light-emitting diodes, can be arranged in the periphery of the mainboard in the boundary of the display screen. The light-emitting diodes are controlled to emit light to light up the light-emitting marker.

[0078] The number of light-emitting diodes can be multiple, which can be arranged in the periphery of the display screen boundary. The display luminance of the light-emitting diodes can be displayed according to the set marker light-emitting intensity or the light-emitting marker luminance.

[0079] In an embodiment of the present application, the arrangement position, shape, and form of the light-emitting marker are not specifically limited.

[0080] The electronic device obtains the second screen light-emitting intensity of the display screen. The electronic device obtains the second screen light-emitting intensity in the same way as the electronic device obtains the first screen light-emitting intensity, which will not be described here.​

[0081] The electronic device determines whether the luminous intensity of the second screen is greater than or equal to a second preset threshold. In one embodiment of this application, the second preset threshold can be set according to actual conditions, for example, the second preset threshold is 150 nits. The second preset threshold is greater than the first preset threshold.

[0082] If the electronic device determines that the luminous intensity of the second screen is greater than or equal to the second set threshold, it turns off the luminous indicator on the display screen and continues to execute the step of obtaining the luminous intensity of the first screen.

[0083] Figure 4 A schematic diagram illustrating the principle of a display method for a display screen according to an embodiment of this application is shown below. Figure 4 As shown, the display screen includes a built-in display screen, a planar beam splitter, and a total internal reflection freeform mirror. The eye can view a virtual image projected behind the display screen. The distance d between the eye and the center of the built-in display screen is 30cm, and the distance D between the eye and the virtual image projected behind the display screen is 500cm. Since the theoretical accommodation of the eye's lens is 1 / 5 = 0.2D, virtual viewing requires almost no lens accommodation. Therefore, through an optical reflection projection scheme, the image displayed on the nearby screen is projected as a magnified virtual image at a distance of D = 500cm, allowing the user's eye to view the displayed image from a distance, thus relaxing the eye's lens.

[0084] When the luminous intensity of the first screen of the display is not less than a first preset threshold, the interface displayed on the display and the virtual image presented behind the display, for example... Figure 3 As shown in Figure a, the interface displays multiple application icons, but the glowing markers are not lit. At this point, you can follow... Figure 4 The principle illustrated here allows the user's gaze to focus on the virtual image appearing behind the display screen. As the luminous intensity of the display screen gradually decreases until it falls below a first preset threshold, the interface displayed on the far-viewing screen gradually darkens, and the virtual image appearing behind the display screen gradually blurs. At this point, the luminous markers on the display screen can be illuminated, and the interface displayed on the screen appears as shown... Figure 3 As shown in b, multiple cross-shaped illuminated marks with a certain brightness are displayed around the perimeter of the screen, based on... Figure 4 As shown in the diagram, the virtual image behind the display screen also displays multiple cross-shaped luminous marks with a certain brightness. These multiple cross-shaped luminous marks can increase the calibration point for the user's eye focus. Thus, even after the display screen dims, the user's eye can still be focused on the virtual image behind the display screen through the luminous marks, reducing the problem of the user's eyes frequently refocusing due to the decrease in the display screen's luminous intensity and alleviating the user's eye fatigue.

[0085] The following is combined Figure 5With a specific embodiment, a display method of a display screen provided by an embodiment of the present application is described in detail, Figure 5 A flowchart of the display method of the display screen provided by an embodiment of the present application is shown in FIG. 2. Figure 5 The method provided in the present application can be a service provided by a system of an electronic device, or a service provided by an application program. As shown in FIG. 1, Figure 5 The method includes the following steps.

[0086] In step 102, the electronic device acquires a first screen luminous intensity of the display screen.

[0087] In an implementation manner of the present application, the electronic device acquires an extra low voltage current of the display screen, and the extra low voltage current is used to represent the first screen luminous intensity. The electronic device can acquire the extra low voltage current of the display screen through a screen driving integrated circuit.

[0088] In another implementation manner of the present application, the electronic device acquires a gray scale of each frame of picture and screen backlight brightness information in the display screen; and generates the first screen luminous intensity according to the gray scale of each frame of picture and the screen backlight brightness information.

[0089] Specifically, the gray scale of each frame of picture and the screen backlight brightness information are calculated according to the following formula to generate the screen luminous intensity.

[0090]

[0091] Wherein, L eve is the screen luminous intensity, L back is the backlight brightness information, G R,n,m is the gray scale of the R pixel of the (n, m)th pixel, G G,n,m is the gray scale of the G pixel of the (n, m)th pixel, G B,n,m is the gray scale of the B pixel of the (n, m)th pixel, K R is the proportion of the R pixel in white light, K G is the proportion of the G pixel in white light, K B is the proportion of the B pixel in white light, n is the horizontal coordinate of the pixel, m is the vertical coordinate of the pixel, N sum is the total number of pixels.

[0092] In another implementation manner of the present application, the electronic device acquires the first screen luminous intensity through a screen luminous intensity sensor.

[0093] In an embodiment of the present application, the screen luminous intensity sensor can be arranged at the lower edge of the display screen of the electronic device, and the specific arrangement position is not limited.

[0094] Step 104, the electronic device determines whether the first screen luminous intensity is less than the first set threshold value, if yes, step 106 is executed; if no, step 102 is executed.

[0095] In an implementation manner of the embodiment of the present application, the electronic device can determine whether the extra low voltage current is less than the current set threshold value, when the extra low voltage current is less than the current set threshold value, it is determined that the first screen luminous intensity is less than the first set threshold value. The current set threshold value can be set according to actual conditions, for example, when the screen of the electronic device is a liquid crystal display (LCD), the current set threshold value is 20 mA. For another example, when the screen of the electronic device is an organic light-emitting diode (OLED), the current set threshold value is 10 mA.

[0096] In an embodiment of the present application, the first set threshold value can be set according to actual conditions, for example, the first set threshold value is 100 nit.

[0097] Step 106, the electronic device lights up the luminous mark of the display screen.

[0098] In an embodiment of the present application, the luminous mark can be set at the periphery of the display screen. The shape of the luminous mark can include a cross mark which is easy to determine the focus. The luminous mark can include a static mark or a dynamic mark, and the dynamic mark can avoid glare. The setting position, shape and form of the luminous mark in the embodiment of the present application are not limited.

[0099] In an implementation manner of the present application, the electronic device can display the luminous mark of the display screen according to the set mark luminous intensity. For example, the set mark luminous intensity is 60 nit.

[0100] In another implementation manner of the present application, the electronic device can acquire the ambient light illumination through the ambient light sensor, can determine the luminous mark brightness according to the ambient light illumination, and light up the luminous mark of the display screen according to the luminous mark brightness. The current ambient light illumination is positively correlated with the luminous mark brightness. Specifically, the electronic device pre-stores the corresponding relationship between the ambient light illumination and the luminous mark brightness, can perform interpolation lookup processing on the ambient light illumination according to the corresponding relationship between the acquired ambient light illumination and the luminous mark brightness, and generate the luminous mark brightness corresponding to the ambient light illumination.

[0101] Table one is a corresponding relationship table of ambient light illumination and luminous mark brightness, and the corresponding relationship between the ambient light illumination and the luminous mark brightness is shown in the following table one.

[0102] Table one

[0103]

[0104]

[0105] As shown in Table 1, the luminance of the light-emitting marker corresponding to the ambient light illumination of 0 Lux is 6 nits, the luminance of the light-emitting marker corresponding to the ambient light illumination of 10 Lux is 20 nits, the luminance of the light-emitting marker corresponding to the ambient light illumination of 50 Lux is 60 nits, the luminance of the light-emitting marker corresponding to the ambient light illumination of 100 Lux is 200 nits, the luminance of the light-emitting marker corresponding to the ambient light illumination of 200 Lux is 450 nits, the luminance of the light-emitting marker corresponding to the ambient light illumination of 500 Lux is 600 nits, the luminance of the light-emitting marker corresponding to the ambient light illumination of 1000 Lux is 1200 nits, the luminance of the light-emitting marker corresponding to the ambient light illumination of 5000 Lux is 2000 nits, and the luminance of the light-emitting marker corresponding to the ambient light illumination of 10000 Lux is 3000 nits.

[0106] In an embodiment of the present application, the interpolation lookup can query whether there is a target value of the ambient light illumination in the corresponding relationship table of the ambient light illumination and the luminance of the light-emitting marker. If there is a target value in the corresponding relationship table, the luminance of the light-emitting marker corresponding to the target value is queried.

[0107] For example, if the ambient light illumination is 50 Lux, the ambient light illumination of 50 Lux is subjected to the interpolation lookup processing according to the obtained corresponding relationship between the ambient light illumination and the luminance of the light-emitting marker, and the luminance of the light-emitting marker corresponding to the ambient light illumination of 50 Lux, i.e., 60 nits, is generated.

[0108] In an implementation manner of the present application, if there is no target value in the corresponding relationship table, the luminance of the light-emitting marker corresponding to the ambient light illumination closest to the target value in the corresponding relationship table can be calculated. For example, if the ambient light illumination is 85 Lux, it can be calculated that the ambient light illumination of 85 Lux is located between 50 Lux and 100 Lux, and since 85 Lux is closer to 100 Lux, the luminance of the light-emitting marker corresponding to the ambient light illumination of 100 Lux, i.e., 200 nits, is taken as the luminance of the light-emitting marker corresponding to the ambient light illumination of 85 Lux, i.e., 200 nits.

[0109] In another implementation manner of the present application, if there is no target value in the corresponding relationship table, a mathematical function approximation manner can also be used to fill in the missing data and generate the luminance of the light-emitting marker corresponding to the target value.

[0110] In step 108, the electronic device obtains the second screen light-emitting intensity of the display screen.

[0111] The manner in which the electronic device obtains the second screen light-emitting intensity is the same as the manner in which the electronic device obtains the first screen light-emitting intensity, which will not be described herein again.

[0112] Step 110, the electronic device determines whether the second screen light intensity is greater than or equal to the second set threshold value, if yes, step 112 is executed; if no, step 108 is executed.

[0113] In an embodiment of the present application, the second set threshold value can be set according to the actual situation, for example, the second set threshold value is 150 nit.

[0114] Optionally, the second set threshold value is greater than the first set threshold value.

[0115] Step 112, the electronic device closes the light-emitting mark of the display screen, and continues to execute step 102.

[0116] In the technical scheme provided by the embodiment of the present application, the first screen light intensity of the display screen is acquired; and when the first screen light intensity is less than the first set threshold value, the light-emitting mark of the display screen is lit. In the technical scheme provided by the embodiment of the present application, when the first screen light intensity is less than the first set threshold value, the light-emitting mark of the display screen is lit, which can increase the calibration point of the visual line focus, so that the display screen can still be focused on the virtual image in the distance through the peripheral light-emitting mark after the display screen is darkened, and the light-emitting mark of the virtual image is lit, which can improve the display effect seen by the human eye, and can also maintain the long-distance view, and the eyes do not need to be frequently focused, thereby reducing the eye fatigue.

[0117] In the technical scheme provided by the embodiment of the present application, the light-emitting mark of the focus alignment can be used to judge the ghosting and distortion, the light-emitting diode (LED) of long-wave red light is used to light the light-emitting mark in the display screen, and the light-emitting mark can also play a certain role in preventing and controlling myopia.

[0118] An embodiment of the present application provides a display device of a display screen, Figure 6 A structural schematic diagram of the display device of the display screen provided by an embodiment of the present application is shown in the figure, Figure 6 The device comprises a first acquisition module 11, a first judgment module 12 and a light-emitting module 13.

[0119] The first acquisition module 11 is used to acquire the first screen light intensity of the display screen.

[0120] The first judgment module 12 is used to judge whether the first screen light intensity is less than the first set threshold value, if it is judged that the first screen light intensity is less than the first set threshold value, the light-emitting module 13 is triggered to light the light-emitting mark of the display screen.

[0121] In an embodiment of the present application, the light-emitting diode of long-wave red light is arranged in the display screen, and the light-emitting module 13 is specifically used to control the light-emitting diode of long-wave red light to emit light.

[0122] In one embodiment of this application, the first acquisition module 11 is specifically used to acquire the additional low voltage current of the screen, which is used to characterize the first screen luminous intensity; or, to acquire the grayscale and screen backlight brightness information of each frame of the screen, and generate the first screen luminous intensity based on the grayscale and screen backlight brightness information of each frame of the screen; or, to acquire the first screen luminous intensity through a screen luminous intensity sensor.

[0123] In one embodiment of this application, the acquisition module 11 is specifically used to acquire the additional low voltage current of the display screen through the screen driver integrated circuit.

[0124] In one embodiment of this application, the light-emitting module 13 is specifically used to illuminate the light-emitting mark on the display screen according to the set light intensity of the mark; or, to obtain the ambient light illuminance, determine the brightness of the light-emitting mark according to the ambient light illuminance, and illuminate the light-emitting mark on the display screen according to the brightness of the light-emitting mark, wherein the ambient light illuminance and the brightness of the light-emitting mark are positively correlated.

[0125] In one embodiment of this application, the light-emitting module 13 is specifically used to perform interpolation lookup processing on the ambient light intensity based on the obtained correspondence between the ambient light intensity and the brightness of the light-emitting mark, and generate the brightness of the light-emitting mark corresponding to the ambient light intensity.

[0126] In one embodiment of this application, the device further includes: a second acquisition module 14, a second judgment module 15, and a closing module 16.

[0127] The second acquisition module 14 is used to acquire the luminous intensity of the second screen of the display.

[0128] The second judgment module 15 is used to determine whether the light intensity of the second screen is greater than or equal to the second set threshold. If it is determined that the light intensity of the second screen is greater than or equal to the second set threshold, the shutdown module 16 is triggered to turn off the light-emitting mark of the display screen, and the first acquisition module 11 is triggered to continue to execute the step of acquiring the light intensity of the first screen.

[0129] In the technical solution provided by this application embodiment, the first screen luminous intensity of the display screen is obtained; when the first screen luminous intensity is less than a first set threshold, the luminous markers of the display screen are illuminated. In the technical solution provided by this application embodiment, when the first screen luminous intensity is less than the first set threshold, illuminating the luminous markers of the physical object on the display screen can increase the calibration point for eye focus, so that even when the display screen is dark, the eye can still focus on the distant virtual image through the surrounding luminous markers. The luminous markers of the virtual image are illuminated, which can improve the display effect seen by the human eye, and can also maintain distance viewing. The eye does not need to frequently adjust focus, thus reducing eye fatigue.
