Display method, device and electronic equipment for display screen Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display method, device, and electronic device for a display screen. Background Art

[0002] With the popularization of paperless and electronic education, students are using electronic products in more and more scenarios.

[0003] As an alternative display device for myopia prevention and control, telescopic screens or light field screens use optical reflection and projection to project a nearby screen into an enlarged virtual image at a distance of more than 3 meters, thereby avoiding close-range eye use and ultimately maintaining long-range eye use and preventing the development of myopia.

[0004] However, current products have many problems. For example, when the brightness of the display screen is reduced to a certain level, the virtual image displayed on the display screen is lower than the brightness of the ambient light reflected into the eye. In this way, the human eye will focus on the reflection plane of the splitter mirror, making it impossible for people to correctly see the content displayed on the display screen and causing difficulty in focusing, resulting in a poor display effect seen by the human eye. Technical issues

[0005] The purpose of this application is to provide a display method, device and electronic device for a display screen to improve the display effect seen by the human eye. Technical Solutions

The ambient light illumination is positively correlated with the brightness of the luminous mark.

[0023] In the technical solution provided in the embodiment of the present application, the brightness of the luminous mark can be determined according to the ambient light illumination, and the luminous mark on the display screen can be lit according to the brightness of the luminous mark. It can be applied to screen display under any ambient light illumination conditions, thereby improving the display effect seen by the human eye.

[0043] Implementation of the Invention

[0044] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention.

[0045] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0046] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0047] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0048] A telescopic screen is a special screen that displays specific images or text to help users exercise their eyes and protect their vision. The principle of a telescopic screen is to stimulate the eye's accommodation function and visual nervous system by adjusting parameters such as the size, clarity, and contrast of the displayed image or text, thereby preventing and controlling myopia. Using a telescopic screen for eye exercises can effectively improve the eye's accommodation ability, reduce eye fatigue, and improve visual comfort. To use a telescopic screen, generally place it at an appropriate distance and height, and then exercise the eyes by viewing the images or text on the screen. Specific exercise methods can be selected based on individual needs and recommendations, such as adjusting focus, eye movement, and changing the focus point.

[0049] The imaging principle of the telescopic screen is shown in FIG. 1A or FIG. 1B .

[0050] FIG1A is a schematic diagram of the principle of a telescopic screen provided in the related art. As shown in FIG1A , the telescopic screen includes a built-in display screen, a plane beam splitter, and a fully reflective free-form mirror. Through the telescopic screen, the eye can view a virtual image presented behind the telescopic 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 telescopic screen is 500 cm. Because the theoretical data for the eye's lens accommodation is 1 / 5 = 0.2D, the eye's virtual distant vision requires almost no lens accommodation. Thus, through an optical reflection projection scheme, the image displayed on the nearby telescopic screen is projected into a magnified virtual image at a distance of D = 500 cm, allowing the user's eye to view the image displayed on the telescopic screen from a distance, while the eye's lens is relaxed.

[0051] Figure 1B is a schematic diagram of the principle of another telescopic screen provided in the related art. As shown in Figure 1B, point A is the center of the concave mirror, the back concave mirror includes points B, D, L, K and C, the semi-transparent reflecting plane mirror includes points E, M and F, points I and J represent the image of the pattern on the liquid crystal screen through the semi-transparent reflecting plane mirror, points H and G represent the pattern on the liquid crystal screen inside the telescopic screen, and points O and N represent the enlarged virtual image formed by the concave mirror.

[0052] The telescopic screen in the related art will display an enlarged virtual image projected from a distance during actual display. When the picture displayed on the telescopic screen is darker, the enlarged virtual image projected from a distance by the telescopic screen disappears, and the eyes can easily observe the actual display content of the telescopic screen nearby, which will cause the human eye to need to focus frequently and increase visual fatigue.

[0053] In order to solve the technical problems in the related art, an embodiment of the present application provides an electronic device.

[0054] In some embodiments, electronic devices include but are not limited to Or devices with other operating systems.

[0055] FIG2 is a schematic diagram of the structure of an electronic device provided according to an embodiment of the present application.

[0059] Processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in processor 110 is a cache memory. This memory can store instructions or data that have just been used or are being recycled by processor 110. If processor 110 needs to use the same instruction or data again, it can directly access the memory.

The mobile communication module 150 may include at least one filter, a switch, a power amplifier, a low noise amplifier (LNA), etc. The mobile communication module 150 can receive electromagnetic waves from the antenna 1, and filter, amplify, and process the received electromagnetic waves, and transmit them to the modulation and demodulation processor for demodulation.

In some embodiments, at least some of the functional modules of the mobile communication module 150 can be set in the processor 110. In some embodiments, at least some of the functional modules of the mobile communication module 150 can be set in the same device as at least some of the modules of the processor 110.

[0064] The wireless communication module 160 can provide wireless communication solutions including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc., applied to the electronic device 100. The wireless communication module 160 can be one or more devices integrating at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via the antenna 2, frequency modulates and filters the electromagnetic wave signals, and sends the processed signals to the processor 110. The wireless communication module 160 can also receive the signal to be sent from the processor 110, frequency modulate it, amplify it, and convert it into electromagnetic waves for radiation through the antenna 2. In one embodiment of the present application, the electronic device 100 can be connected to an external display screen for communication, or the electronic device 100 includes a display screen 194.

[0065] The electronic device 100 implements display functions through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing and is connected to the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 110 may include one or more GPUs that execute program instructions to generate or change display information. The display screen 194 is used to display images, videos, etc. The display screen 194 includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a MiniLED, a MicroLED, a Micro-oLed, a quantum dot light-emitting diode (QLED), etc. In some embodiments, the electronic device 100 may include one or N display screens 194, where N is a positive integer greater than one.

[0066] In one embodiment of the present application, the display screen 194 may be a light field screen or a telescopic screen, and the electronic device 100 may also be communicatively connected to an external display screen, which may be a light field screen or a telescopic screen.

[0067] The electronic device 100 can implement audio functions such as music playback and recording through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headphone jack 170D, and the application processor.

[0068] Based on the electronic device in FIG2 , the display method of the display screen provided in the embodiment of the present application is described in detail below in combination with FIG3 and FIG4 .

[0069] 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, and the extra low voltage current is used to represent the first screen luminous intensity; or the electronic device obtains grayscale and screen backlight brightness information of each frame of the display screen, and generates the first screen luminous intensity according to the grayscale and screen backlight brightness information of each frame of the display screen; or the electronic device obtains the first screen luminous intensity through a screen luminous intensity sensor. The electronic device can obtain the extra low voltage current of the display screen through a screen driver integrated circuit (IC).

[0070] The electronic device determines whether the luminous intensity of the first screen is less than the first set threshold. In one implementation of an embodiment of the present application, the electronic device can determine whether the additional low-voltage current is less than the current setting threshold. When the additional low-voltage current is less than the current setting threshold, it is determined that the screen luminous intensity is less than the set threshold. Among them, the current setting 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 setting threshold is 20mA. For another example, when the screen of the electronic device is an organic laser display (OLED), the current setting threshold is 10mA. In one embodiment of the present application, the first setting threshold can be set according to actual conditions. For example, the first setting threshold is 100nit.

[0071] If the electronic device determines that the luminous intensity of the first screen is less than the first set threshold, the luminous mark of the display screen is lit.

[0072] In one embodiment of the present application, the luminous mark may be a pattern displayed on a display screen. Accordingly, lighting up the luminous mark on the display screen may be achieved by displaying a preset pattern on the display screen.

[0073] FIG3 is a schematic diagram of a display change of a display screen provided by an embodiment of the present application. When the luminous intensity of the first screen of the display screen is not less than a first set threshold value, the interface displayed on the display screen and the virtual image presented behind the display screen are as shown in FIG3a. Multiple application icons are displayed in the interface, and the luminous mark is not lit.

[0074] The number of luminous marks 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 four sides within the boundary of the display screen, for example, as shown in Figure 3b, multiple cross-shaped luminous marks are set around the boundary of the display screen.

[0075] The brightness of each pixel in the preset pattern may be the same or different. For ease of processing, the brightness of each pixel in the preset pattern may be the same. Multiple pixels may form a luminous mark. In one implementation of the present application, the electronic device may light up the luminous mark on the display screen and display it according to the set mark luminous intensity. For example, the mark luminous intensity is set to 60nit. In another implementation of the present application, the electronic device may obtain the ambient light illumination through an ambient light sensor, determine the luminous mark brightness according to the ambient light illumination, and light up the luminous mark on the display screen according to the luminous mark brightness. The ambient light illumination is positively correlated with the luminous mark brightness. The brighter the ambient light illumination, the higher the luminous mark brightness. Specifically, the ambient light illumination may be interpolated and searched based on the corresponding relationship between the obtained ambient light illumination and the luminous mark brightness to generate the luminous mark brightness corresponding to the ambient light illumination.

[0076] The luminous markers can be static markers or dynamic markers.

[0077] A static mark refers to a luminous mark whose position and brightness on the display screen remain unchanged. For example, a static mark is a cross-shaped luminous mark with a brightness of 60 nit on all sides within the boundary of the display screen.

[0078] A dynamic mark refers to a pattern whose position and / or brightness can change. For example, a dynamic mark can be a cross mark that moves along a set trajectory and a set movement speed. The set trajectory and the set movement speed can be set according to actual conditions. For example, the set trajectory is a clockwise trajectory along the four sides of the boundary of the display screen, and the set movement speed includes setting an angular velocity of 2 rad / s and a linear velocity of 1 m / s. For example, as shown in Figure 3c, multiple cross-shaped luminous marks set around the boundary of the display screen move and are displayed along a clockwise trajectory along the four sides of the boundary of the display screen.

[0079] In some embodiments, light emitting devices, such as light emitting diodes, may be provided around the mainboard within the boundary. The light emitting diodes are controlled to emit light to illuminate the luminous mark.

[0080] There can be multiple LEDs, which can be arranged around the border of the display screen. The display brightness of the LEDs can be displayed according to the above-mentioned set mark luminous intensity or luminous mark brightness.

[0081] In one embodiment of the present application, the location, shape, and form of the luminous mark are not specifically limited.

[0082] The electronic device obtains the second screen luminous intensity of the display screen. The electronic device obtains the second screen luminous intensity in the same manner as the electronic device obtains the first screen luminous intensity, which will not be repeated here.

[0083] The electronic device determines whether the luminous intensity of the second screen is greater than or equal to a second set threshold. In one embodiment of the present application, the second set threshold can be set according to actual conditions, for example, the second set threshold is 150 nits. The second set threshold is greater than the first set threshold.

[0084] 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 mark of the display screen and continues to execute the step of obtaining the luminous intensity of the first screen.

[0085] FIG4 is a schematic diagram of the principle of a display method of a display screen provided by an embodiment of the present application. As shown in FIG4 , the display screen includes a built-in display screen, a plane beam splitter, and a total reflection free-form mirror. The eye can view the virtual image presented behind the display screen through the display 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 display screen is 500 cm. Since the theoretical data of the lens adjustment of the eye is 1 / 5=0.2D, the virtual vision of the eye hardly requires lens adjustment. Therefore, through the optical reflection projection scheme, the display image of the nearby display screen is projected into an enlarged virtual image at a distance of D=500 cm, so that the user's eyes can view the display image of the display screen from a distance through the display screen, and the lens of the eye is relaxed.

[0086] When the luminous intensity of the first screen of the display screen is not less than the first set threshold, the interface displayed on the display screen and the virtual image presented behind the display screen are, for example, as shown in FIG3a. Multiple application icons are displayed in the interface, and the luminous mark is not lit. At this time, the user's line of sight can be focused on the virtual image presented behind the display screen according to the principle shown in FIG4. When the luminous intensity of the display screen gradually decreases until it is less than the first set threshold, the interface displayed on the telescopic screen gradually becomes black, and the virtual image presented behind the display screen gradually becomes blurred. At this time, the luminous mark of the display screen can be lit, and the interface displayed on the display screen is shown in FIG3b. Multiple cross-shaped luminous marks with a certain brightness are displayed around the display screen. Based on the principle shown in FIG4, multiple cross-shaped luminous marks with a certain brightness are also displayed on the virtual image presented behind the display screen. The above-mentioned multiple cross-shaped luminous marks can increase the calibration points for the user's line of sight to be focused, so that after the display screen is dark, the user's line of sight can still be focused on the virtual image presented behind the display screen through the luminous marks, reducing the problem of frequent focusing of the user's eyes caused by the reduction in the luminous intensity of the display screen, and alleviating the user's eye fatigue.

[0087] The following describes a display method for a display screen provided by an embodiment of the present application in detail using FIG5 as a specific embodiment. FIG5 is a flow chart of a display method for a display screen provided by an embodiment of the present application. The method provided in FIG5 can be a service provided by a system of an electronic device or a service provided by an application. As shown in FIG5 , the method includes:

[0088] Step 102: The electronic device obtains a first screen luminous intensity of the display screen.

[0089] In one implementation of the present application, the electronic device obtains an extra low-voltage current from the display screen, and the extra low-voltage current is used to represent the luminous intensity of the first screen. The electronic device can obtain the extra low-voltage current from the display screen through a screen driver integrated circuit.

[0090] In another implementation of the present application, the electronic device obtains the grayscale and screen backlight brightness information of each frame in the display screen; and generates a first screen luminous intensity based on the grayscale and screen backlight brightness information of each frame.

[0091] Specifically, the grayscale and screen backlight brightness information of each frame are calculated using the following formula to generate the screen luminous intensity.

[0092] Among them, L eve is the screen luminous intensity, L back is the backlight brightness information, G R,n,m is the grayscale of the R pixel of the (n, m)th pixel, G G,n,m is the grayscale of the G pixel of the (n, m)th pixel, GB,n,m is the grayscale of the B pixel of the (n, m)th pixel, K R is the proportion of R pixels in white light, K G is the proportion of G pixels in white light, K B is the proportion of B pixels 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.

[0093] In another implementation of the present application, the electronic device obtains the first screen luminous intensity through a screen luminous intensity sensor.

[0094] In one embodiment of the present application, the screen luminous intensity sensor can be set at the lower edge of the display screen of the electronic device, and the specific setting position is not limited.

[0095] Step 104 , the electronic device determines whether the luminous intensity of the first screen is less than a first set threshold value. If so, execute step 106 ; if not, execute step 102 .

[0096] In one implementation of the embodiment of the present application, the electronic device can determine whether the additional low voltage current is less than the current setting threshold. When the additional low voltage current is less than the current setting threshold, it is determined that the luminous intensity of the first screen is less than the first setting threshold. The current setting 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 setting threshold is 20mA. For another example, when the screen of the electronic device is an organic light-emitting diode (OLED), the current setting threshold is 10mA.

[0097] In one embodiment of the present application, the first set threshold can be set according to actual conditions. For example, the first set threshold is 100 nit.

[0098] Step 106: The electronic device lights up the luminous mark on the display screen.

[0099] In one embodiment of the present application, luminous markers can be positioned around the perimeter of the display screen. The shape of the luminous markers can include a cross-shaped mark that easily identifies focus. The luminous markers can be static or dynamic, with dynamic markers being more effective at reducing glare. The placement, shape, and presentation of the luminous markers in the embodiments of the present application are not specifically limited.

[0100] In one implementation of the present application, the electronic device may display a luminous mark on a display screen according to a set mark luminous intensity, for example, the set mark luminous intensity is 60 nit.

[0101] In another implementation of the present application, an electronic device can obtain ambient light illumination via an ambient light sensor, determine the brightness of a luminous marker based on the ambient light illumination, and illuminate the luminous marker on the display screen based on the brightness of the luminous marker. The current ambient light illumination is positively correlated with the brightness of the luminous marker. Specifically, the electronic device pre-stores a correspondence between ambient light illumination and the brightness of the luminous marker. Based on the obtained correspondence between the ambient light illumination and the brightness of the luminous marker, an interpolation search process can be performed on the ambient light illumination to generate the brightness of the luminous marker corresponding to the ambient light illumination.

[0102] Table 1 is a table showing the corresponding relationship between ambient light illumination and the brightness of the luminous mark. The corresponding relationship between ambient light illumination and the brightness of the luminous mark is shown in Table 1 below.

[0103] Table 1

[0104] As shown in Table 1 above, the brightness of the luminous mark corresponding to an ambient light illumination of 0 Lux is 6 nits, the brightness of the luminous mark corresponding to an ambient light illumination of 10 Lux is 20 nits, the brightness of the luminous mark corresponding to an ambient light illumination of 50 Lux is 60 nits, the brightness of the luminous mark corresponding to an ambient light illumination of 100 Lux is 200 nits, the brightness of the luminous mark corresponding to an ambient light illumination of 200 Lux is 450 nits, the brightness of the luminous mark corresponding to an ambient light illumination of 500 Lux is 600 nits, the brightness of the luminous mark corresponding to an ambient light illumination of 1000 Lux is 1200 nits, the brightness of the luminous mark corresponding to an ambient light illumination of 5000 Lux is 2000 nits, and the brightness of the luminous mark corresponding to an ambient light illumination of 10000 Lux is 3000 nits.

[0105] In one embodiment of the present application, interpolation search can query whether there is a target value of ambient light illumination in the correspondence table between ambient light illumination and luminous mark brightness. If there is a target value in the correspondence table, the luminous mark brightness corresponding to the target value is queried.

[0106] For example, if the ambient light illuminance is 50 Lux, the ambient light illuminance of 50 Lux is interpolated and searched according to the acquired correspondence between the ambient light illuminance and the brightness of the luminous mark to generate the luminous mark brightness of 60 nits corresponding to the ambient light illuminance of 50 Lux.

[0107] In one implementation of the present application, if there is no target value in the correspondence table, the brightness of the luminous mark corresponding to the ambient light illuminance closest to the target value in the correspondence table can be calculated. For example, if the ambient light illuminance is 85 Lux, it can be calculated that the ambient light illuminance of 85 Lux is between 50 Lux and 100 Lux. Since 85 Lux is closer to 100 Lux, the brightness of the luminous mark corresponding to an ambient light illuminance of 100 Lux, 200 nits, is used as the brightness of the luminous mark corresponding to an ambient light illuminance of 85 Lux.

[0108] In another implementation of the present application, if there is no target value in the correspondence table, a mathematical function approximation method can be used to fill in the missing data to generate the brightness of the luminous mark corresponding to the target value.

[0109] Step 108: The electronic device obtains a second screen luminous intensity of the display screen.

[0110] The way in which the electronic device obtains the luminous intensity of the second screen is the same as the way in which the electronic device obtains the luminous intensity of the first screen, and will not be repeated here.

[0111] Step 110 , the electronic device determines whether the luminous intensity of the second screen is greater than or equal to a second set threshold value. If so, execute step 112 ; if not, execute step 108 .

[0112] In one embodiment of the present application, the second set threshold can be set according to actual conditions. For example, the second set threshold is 150 nit.

[0113] Optionally, the second set threshold is greater than the first set threshold.

[0114] Step 112 : The electronic device turns off the luminous mark on the display screen and continues to execute step 102 .

[0115] In the technical solution provided by the embodiment of the present application, the luminous intensity of the first screen of the display screen is obtained; when the luminous intensity of the first screen is less than a first set threshold, the luminous mark of the display screen is illuminated. In the technical solution provided by the embodiment of the present application, when the luminous intensity of the first screen is less than the first set threshold, the luminous mark of the real object on the display screen is illuminated, which can increase the calibration point of visual focus, so that after the display screen is darkened, the luminous mark of the surrounding object can still be focused on the distant virtual image. The luminous mark of the virtual image is electrically illuminated, which can improve the display effect seen by the human eye and maintain distant vision. The eyes do not need to frequently adjust the focus, thereby reducing eye fatigue.

[0116] In the technical solution provided in the embodiment of the present application, the focused and aligned luminous marks can be used to judge ghosting and distortion. The long-wave red light-emitting diode (LED) is used in the display screen to illuminate the luminous marks, which can also play a certain role in preventing and controlling myopia.

As shown in FIG6 , the device includes: a first acquisition module 11 , a first judgment module 12 and a light-emitting module 13 .

[0118] The first acquisition module 11 is used to acquire a first screen luminous intensity of the display screen.

[0119] The first judging module 12 is used to judge whether the luminous intensity of the first screen is less than a first set threshold value. If it is judged that the luminous intensity of the first screen is less than the first set threshold value, the lighting module 13 is triggered to light up the luminous mark of the display screen.

[0120] In one embodiment of the present application, a long-wave red light emitting diode is provided in the display screen, and the light emitting module 13 is specifically used to control the long-wave red light emitting diode to emit light.

[0121] In one embodiment of the present application, the first acquisition module 11 is specifically used to obtain an additional low-voltage current of the screen, and the additional low-voltage current is used to characterize the first screen luminous intensity; or, to obtain the grayscale and screen backlight brightness information of each frame in the screen, and generate the first screen luminous intensity based on the grayscale and screen backlight brightness information of each frame; or, to obtain the first screen luminous intensity through a screen luminous intensity sensor.

[0122] In one embodiment of the present application, the acquisition module 11 is specifically configured to acquire additional low-voltage current of the display screen through a screen driver integrated circuit.

[0123] In one embodiment of the present application, the light-emitting module 13 is specifically used to light up the light-emitting mark on the display screen and display it according to the set mark light intensity; or, obtain the ambient light illumination, determine the brightness of the light-emitting mark based on the ambient light illumination, and light up the light-emitting mark on the display screen according to the brightness of the light-emitting mark, and the ambient light illumination is positively correlated with the brightness of the light-emitting mark.

[0124] In one embodiment of the present application, the light emitting module 13 is specifically configured to perform interpolation search processing on the ambient light illumination according to the acquired correspondence between the ambient light illumination and the brightness of the light emitting mark, and generate the brightness of the light emitting mark corresponding to the ambient light illumination.

[0125] In one embodiment of the present application, the device further includes: a second acquisition module 14 , a second judgment module 15 and a closing module 16 .

[0126] The second acquisition module 14 is used to acquire a second screen luminous intensity of the display screen.

[0127] The second judgment module 15 is used to determine whether the luminous intensity of the second screen is greater than or equal to the second set threshold. If it is determined that the luminous intensity of the second screen is greater than or equal to the second set threshold, the closing module 16 is triggered to turn off the luminous mark of the display screen, and the first acquisition module 11 is triggered to continue to execute the step of obtaining the luminous intensity of the first screen.

[0128] In the technical solution provided by the embodiment of the present application, the luminous intensity of the first screen of the display screen is obtained; when the luminous intensity of the first screen is less than a first set threshold, the luminous mark of the display screen is illuminated. In the technical solution provided by the embodiment of the present application, when the luminous intensity of the first screen is less than the first set threshold, the luminous mark of the real object on the display screen is illuminated, which can increase the calibration point of visual focus, so that after the display screen is darkened, the luminous mark of the surrounding object can still be focused on the distant virtual image. The luminous mark of the virtual image is electrically illuminated, which can improve the display effect seen by the human eye and maintain distant vision. The eyes do not need to frequently adjust the focus, thereby reducing eye fatigue.
