Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display method, device and electronic equipment 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 solutions to project a nearby screen into an enlarged virtual image at a distance of more than 3m, 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 dichroic plane 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. Summary of the invention

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

[0006] The present application embodiment adopts the following technical solutions:

[0008] Get the first screen luminous intensity of the display screen;

[0009] When the luminous intensity of the first screen is less than the first set threshold, the luminous mark of the display screen is lit.

[0010] In the technical solution provided in the embodiment of the present application, 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 real object on the display screen is lit up to increase the calibration point of the line of sight focus, so that after the display screen is dimmed, the user's line of sight can still be focused on the distant virtual image through the surrounding luminous marks. The luminous marks of the virtual image are lit up, which can improve the display effect seen by the human eye and maintain distant vision. The eyes do not need to focus frequently, which reduces eye fatigue.

[0011] In an implementation of the first aspect, a long-wave red light emitting diode is provided in the display screen, and lighting up the luminous mark of the display screen includes:

[0012] Control the light emitting diode of long wave red light to emit light.

[0013] In the technical solution provided in the embodiment of the present application, the long-wave red light emitting diodes arranged in the display screen can play a certain role in preventing and controlling myopia.

[0017] The first screen luminous intensity is obtained through a screen luminous intensity sensor.

[0018] In the technical solution provided in the embodiment of the present application, the luminous intensity of the first screen can be obtained in a variety of ways. Different electronic products can use different ways of obtaining the luminous intensity of the first screen, thereby reducing the production cost of the electronic device.

[0019] In an implementation of the first aspect, obtaining an additional low-voltage current of a display screen includes:

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 applicable to screen display under any ambient light illumination conditions, thereby improving the display effect seen by the human eye.

[0024] In an implementation of the first aspect, determining the brightness of the luminous mark according to the ambient light illumination includes:

[0025] The ambient light illumination is interpolated and searched according to the acquired corresponding relationship between the ambient light illumination and the brightness of the luminous mark, so as to generate the brightness of the luminous mark corresponding to the ambient light illumination.

When the luminous intensity of the second screen is too large, the luminous mark of the display screen is turned off, so that the display screen can always be in a state of appropriate luminous intensity, thereby reducing the fatigue of the human eyes.

[0042] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but should not be construed as limiting the present invention.

[0043] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are 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 specific embodiments, and are not intended to limit the embodiments of the present application. The singular forms of "a", "said" 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 other meanings.

[0045] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0046] A telescopic screen is a special screen that can help users exercise their eyes and protect their vision by displaying specific images or text. The principle of a telescopic screen is to stimulate the eye's adjustment function and visual nervous system by adjusting the size, clarity, contrast and other parameters of the displayed image or text, thereby achieving the effect of preventing and controlling myopia. Using a telescopic screen for eye exercises can effectively improve the eye's adjustment ability, reduce eye fatigue, and improve visual comfort. The method of using a telescopic screen is generally to place it at an appropriate distance and height, and then exercise the eyes by watching the images or text on the screen. The specific exercise method can be selected according to personal needs and suggestions, such as adjusting the focus, eye movement, and changing the gaze point.

[0047] Among them, the imaging principle of the telephoto screen is as follows Figure 1A or Figure 1B shown.

[0048] Figure 1A A schematic diagram of the principle of a telescopic screen provided in the related art is shown in FIG. Figure 1A As shown, the telephoto screen includes a built-in display screen, a plane beam splitter and a total reflection free-form mirror. The eyes can view the virtual image presented behind the telephoto screen through the telephoto screen. Among them, the distance d between the eyes and the center of the built-in display screen is 30cm, and the distance D between the eyes and the virtual image presented behind the telephoto screen is 500cm. Because the theoretical data of the lens adjustment of the eye is 1 / 5=0.2D, the virtual vision of the eye almost does not require lens adjustment. Therefore, through the optical reflection projection scheme, the display image of the telephoto screen at a distance of D=500cm is projected into an enlarged virtual image, so that the user's eyes can view the display image of the telephoto screen from a distance through the telephoto screen, and the lens of the eye is relaxed.

[0049] Figure 1B A schematic diagram of another telescopic screen provided in the related art is shown in FIG. Figure 1B As shown, 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 LCD screen formed by the semi-transparent reflecting plane mirror, points H and G represent the pattern on the LCD screen inside the telephoto screen, and points O and N represent the enlarged virtual image formed by the concave mirror.

[0050] The telephoto screen in the related art will display an enlarged virtual image projected from a distance during actual display. When the picture displayed on the telephoto screen is darker, the enlarged virtual image projected from a distance by the telephoto screen disappears, and the eyes can easily observe the actual display content of the telephoto screen nearby, which will cause the human eye to need to focus frequently and increase visual fatigue.

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

[0052] In some embodiments, electronic devices include but are not limited to those equipped with Hongmeng Or devices with other operating systems.

[0057] The processor 110 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store instructions or data that the processor 110 has just used or cyclically used.

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.

[0063] The electronic device 100 implements the display function through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing, which connects 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, which execute program instructions to generate or change display information.

[0066] based on Figure 2 The electronic equipment in the following Figure 3 and Figure 4 The display method of the display screen provided in the embodiment of the present application is described in detail.

[0067] The electronic device obtains the first screen luminous intensity of the display screen. Specifically, the electronic device obtains the extra low voltage current (Elvss) of the display screen, and the extra low voltage current is used to characterize the first screen luminous intensity; or, the electronic device obtains the grayscale and screen backlight brightness information of each frame in the display screen, and generates the first screen luminous intensity according to the grayscale and screen backlight brightness information of each frame; or, the electronic device obtains the first screen luminous intensity through a screen luminous intensity sensor. Among them, the electronic device can obtain the extra low voltage current of the display screen through a screen driver integrated circuit (IC).

[0068] 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 (Liquid Crystal Display, LCD for short), the current setting threshold is 20mA. For another example, when the screen of the electronic device is an organic laser display (Organic Light-Emitting Diode, OLED for short), 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.

[0069] 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.

[0070] 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 of the display screen may be achieved by displaying a preset pattern on the display screen.

[0071] Figure 3 A schematic diagram of display change of a display screen provided by an embodiment of the present application, when the first screen luminous intensity of the display screen is not less than a first set threshold, the interface displayed on the display screen and the virtual image presented behind the display screen are, for example, Figure 3 As shown in a, multiple application icons are displayed in the interface, and the luminous mark is not lit

[0072] The number of the luminous marks may be multiple, for example, the shape of the luminous marks may be a cross, for example, the positions of the luminous marks may be around the border of the display screen, for example, Figure 3 As shown in b, a plurality of cross-shaped luminous marks are arranged around the border of the display screen.

[0073] 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 of 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 brightness of the luminous mark according to the ambient light illumination, and light up the luminous mark of the display screen according to the brightness of the luminous mark. The ambient light illumination is positively correlated with the brightness of the luminous mark. The brighter the ambient light illumination, the higher the brightness of the luminous mark. Specifically, the ambient light illumination may be interpolated and searched according to the corresponding relationship between the acquired ambient light illumination and the brightness of the luminous mark to generate the brightness of the luminous mark corresponding to the ambient light illumination.

[0074] The luminous markers can be static markers or dynamic markers.

[0075] 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 border of the display screen.

[0076] A dynamic mark means that the position and / or brightness of the pattern can change. For example, the dynamic mark can be a cross mark that moves along 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 four sides of the boundary of the display screen, and the set moving speed includes setting the moving angular velocity of 2rad / s and setting the moving linear velocity of 1m / s. For example, Figure 3 As shown in c, a plurality of cross-shaped luminous marks arranged around the boundary of the display screen are displayed by moving in a clockwise trajectory around the boundary of the display screen.

[0077] In some embodiments, light emitting devices may be arranged around the main board within the boundary, for example, the light emitting devices may be light emitting diodes. The light emitting mark is lit by controlling the light emitting diodes to emit light.

[0078] There can be multiple light emitting diodes, which can be arranged around the border of the display screen. The display brightness of the light emitting diodes can be displayed according to the above-mentioned set mark luminous intensity or luminous mark brightness.

[0079] In one embodiment of the present application, the location, shape, and form of the luminous mark are not specifically limited.

[0080] 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 described in detail here.

[0081] The electronic device determines whether the luminous intensity of the second screen is greater than or equal to the 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 150n it. The second set threshold is greater than the first set 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, the luminous mark of the display screen is turned off, and the step of obtaining the luminous intensity of the first screen is continued.

[0083] Figure 4 A schematic diagram of a display method for a display screen provided by an embodiment of the present application is shown as follows: Figure 4 As shown, 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. Among them, 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. Because the theoretical data of the lens adjustment of the eye is 1 / 5=0.2D, the virtual vision of the eye almost does not require 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.

[0084] When the first screen luminous intensity 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, Figure 3 As shown in a, multiple application icons are displayed in the interface, and the luminous mark is not lit. At this time, you can follow Figure 4 The principle shown in FIG. 1 is to realize that the user's sight is focused on the virtual image presented behind the display screen; 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 as shown in FIG. Figure 3 As shown in b, multiple cross-shaped luminous marks with a certain brightness are displayed around the display screen. Figure 4 According to the principle shown, the virtual image presented behind the display screen also displays multiple cross-shaped luminous marks with a certain brightness. The multiple cross-shaped luminous marks can increase the calibration points for the user's line of sight to focus, so that after the display screen is darkened, the luminous marks can still be used to focus the user's line of sight on the virtual image presented behind the display screen, thereby reducing the problem of frequent focusing of the user's eyes caused by the reduction of the luminous intensity of the display screen and alleviating the user's eye fatigue.

[0085] Combine the following Figure 5A display method for a display screen provided by an embodiment of the present application is described in detail with a specific embodiment. Figure 5 A flowchart of a display method of a display screen provided in one embodiment of the present application. Figure 5 The method provided in the method may be a service provided by the system of the electronic device, or a service provided by an application. Figure 5 As shown, the method includes:

[0086] Step 102: The electronic device obtains a first screen luminous intensity of the display screen.

[0087] In one implementation of the present application, the electronic device obtains an extra low voltage current of the display screen, and the extra low voltage current is used to characterize the luminous intensity of the first screen. The electronic device can obtain the extra low voltage current of the display screen through a screen driver integrated circuit.

[0088] 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.

[0089] Specifically, the grayscale and screen backlight brightness information of each frame are calculated using the following formula to generate the screen luminous intensity.

[0090]

[0091] 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, G B,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.

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

[0093] 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.

[0094] Step 104 , the electronic device determines whether the luminous intensity of the first screen is less than a first set threshold value, and if so, executes step 106 ; if not, executes step 102 .

[0095] 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 laser display (OLED), the current setting threshold is 10mA.

[0096] 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.

[0097] Step 106: The electronic device lights up the luminous mark on the display screen.

[0098] In one embodiment of the present application, the luminous mark can be set around the display screen. The shape of the luminous mark can include a cross mark that is easy to judge whether the focus is clear. The luminous mark can include a static mark or a dynamic mark, and the dynamic mark can avoid glare. The setting position, shape, and expression form of the luminous mark in the embodiment of the present application are not specifically limited.

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

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

[0101] Table 1 is a table of corresponding relationships between ambient light illumination and brightness of luminous marks. The corresponding relationships between ambient light illumination and brightness of luminous marks are shown in Table 1 below.

[0102] Table 1

[0103]

[0104]

[0105] 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.

[0106] 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.

[0107] For example, if the ambient light illuminance is 50 Lux, the ambient light illuminance 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 60 nits corresponding to the ambient light illuminance 50 Lux.

[0108] 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 illumination closest to the target value in the correspondence 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 between 50 Lux and 100 Lux. Since 85 Lux is closer to 100 Lux, the brightness of the luminous mark corresponding to the ambient light illumination of 100 Lux is 200 nits as the brightness of the luminous mark corresponding to the ambient light illumination of 85 Lux.

[0109] 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.

[0110] Step 108: The electronic device obtains the second screen luminous intensity of the display screen.

[0111] 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, which will not be repeated here.

[0112] Step 110 , the electronic device determines whether the luminous intensity of the second screen is greater than or equal to the second set threshold value, and if so, executes step 112 ; if not, executes step 108 .

[0113] 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.

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

[0115] Step 112: The electronic device turns off the luminous mark on the display screen and continues to execute step 102.

[0116] 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 the first set threshold, the luminous mark of the display screen is lit. 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 lit, which can increase the calibration point of the line of sight focus, so that after the display screen is darkened, the luminous mark of the surrounding can still be focused on the distant virtual image. The luminous mark of the virtual image is electrically lit, which can improve the display effect seen by the human eye and maintain the distant view. The eyes do not need to adjust the focus frequently, which reduces eye fatigue.

[0117] 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 display screen uses a long-wave red light-emitting diode (LED) to illuminate the luminous marks, which can also play a certain role in preventing and controlling myopia.

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

[0120] 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 luminous module 13 is triggered to light up the luminous mark of the display screen.

[0121] 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 light emitting diode of the long-wave red light.

[0122] In one embodiment of the present application, the first acquisition module 11 is specifically used to acquire 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 acquire the grayscale and screen backlight brightness information of each frame in the screen, and generate the first screen luminous intensity according to the grayscale and screen backlight brightness information of each frame; or, to acquire the first screen luminous intensity through a screen luminous intensity sensor.

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

[0125] In one embodiment of the present application, the light emitting module 13 is specifically used to perform interpolation search processing on the ambient light illumination according to the acquired correspondence relationship 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.

[0126] In an embodiment of the present application, the device further includes: a second acquisition module 14 , a second determination module 15 and a closing module 16 .

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

[0128] The second judgment module 15 is used to judge whether the luminous intensity of the second screen is greater than or equal to the second set threshold. If it is judged 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 acquiring the luminous intensity of the first screen.

[0129] In the technical solution provided by the embodiment of the present application, the first screen luminous intensity of the display screen is obtained; when the first screen luminous intensity is less than the first set threshold, the luminous mark of the display screen is lit. In the technical solution provided by the embodiment of the present application, when the first screen luminous intensity is less than the first set threshold, the luminous mark of the real object on the display screen is lit, which can increase the calibration point of the line of sight focus, so that after the display screen is darkened, the luminous mark of the surrounding can still be focused on the distant virtual image. The luminous mark of the virtual image is electrically lit, which can improve the display effect seen by the human eye and maintain the distant view. The eyes do not need to adjust the focus frequently, which reduces eye fatigue.
