As shown in fig. 1, fig. 1 is a schematic structural diagram of an electronic device provided in an embodiment of the present application, and as shown in fig. 1, the electronic device includes: the display screen comprises a light-transmitting cover plate 10, a display screen 20 and an optical device 30, wherein the light-transmitting cover plate 10 covers the display screen 20 and the optical device 30;
the display screen 20 includes a first display portion 21 and a second display portion 22, the light-transmitting cover plate 10 includes a first light-transmitting portion 11 and a second light-transmitting portion 12, the first display portion 21 is disposed toward the first light-transmitting portion 11, and a first included angle is formed between the first light-transmitting portion 11 and the first display portion 21; the second display part 22 is arranged opposite to and parallel to the second transparent part 12, and light emitted from the second display part 22 is emitted from the second transparent part 12;
the first included angle is an acute angle, and light is in the first light transmission portion 11 can be deflected, so that light emitted by the first display portion 21 forms a full-screen display after being refracted by the first light transmission portion 11, or external light is received by the optical device 30 after being refracted by the first light transmission portion 11.
Note that, a in fig. 1 and 2 indicates a path through which the external light is irradiated to the optical device 30 after being refracted by the first transparent portion 11, and fig. 2 is an enlarged view of an area C in fig. 1.
The working principle of the embodiment of the application can be referred to as the following expression:
since the external light can be received by the optical device 30 after being refracted by the first light transmission part 11, that is, the external light can be irradiated onto the optical device 30 without passing through the display screen 20, the light transmission of the light is enhanced, the number of the light irradiated onto the optical device 30 is increased, and the light receiving effect of the optical device 30 is further enhanced. In addition, since the light emitted from the first display portion 21 is refracted by the first light transmission portion 11 to form a full-screen display, and the light emitted from the second display portion 22 is emitted from the second light transmission portion 21, the display effect of the display screen 20 is better, and the screen occupation ratio of the electronic device is higher.
The light emitted from the first display portion 21 is refracted by the first light transmission portion 11 to form a full-screen display, and it can be understood that: the light that first display portion 21 sent can make each position of first printing opacity portion 11 all have the light to incide to external environment after the refraction of first printing opacity portion 11, simultaneously, because the light that second display portion 22 sent jets out from second printing opacity portion 12 back, then each position of second printing opacity portion 12 also all has the light to incide to external environment, like this, make each position on the printing opacity apron 10 all have the light to incide to external environment, thereby show the effect of full screen display.
It should be noted that the type of the optical device 30 is not limited herein, and as an alternative implementation, the optical device 30 may be a camera module, so that the receiving effect of the camera module on the light is enhanced, and the imaging effect of the camera module can be enhanced. Of course, the optical device 30 may also be other devices, such as an optical sensor.
The material for manufacturing the light-transmitting cover plate 10 is not limited herein, and for example: when the light-transmissive cover plate 10 is made of a glass material, the light-transmissive cover plate 10 may also be referred to as a glass cover plate.
Wherein, since the transparent cover plate 10 covers the display screen 20 and the optical device 30, and the optical device 30 can be located at one side of the edge of the display screen 20, the area of the vertical projection of the display screen 20 on the transparent cover plate 10 is smaller than the area of the transparent cover plate 10.
In addition, the installation position of the optical device 30 can also be understood as follows: the optical device 30 may be disposed adjacent to the edge of the display screen 20 and the transparent cover plate 10, respectively, that is, the optical device 30 and the display screen 20 are both located on the same side of the transparent cover plate 10, and the optical device 30 is disposed close to one side of the edge of the display screen 20, and the sum of the areas of the vertical projections of the optical device 30 and the display screen 20 on the transparent cover plate 10 may be smaller than or equal to the area of the transparent cover plate 10.
It should be noted that, since the optical device 30 is disposed near one side of the edge of the display screen 20, that is, the position of the optical device 30 is usually located at the edge of the display screen 20, if the area where the optical device 30 is located is in a non-display state, the influence on the overall display effect of the display screen 20 of the electronic device is small.
The light-transmitting cover plate 10 includes a first light-transmitting portion 11 and a second light-transmitting portion 12, the display screen 20 includes a first display portion 21 and a second display portion 22, it can be understood that the first display portion 21 is disposed corresponding to the first light-transmitting portion 11, the second display portion 22 is disposed corresponding to the second light-transmitting portion 12, in addition, an orthographic projection of the first display portion 21 on the light-transmitting cover plate 10 may coincide with the first light-transmitting portion 11, and similarly, an orthographic projection of the second display portion 22 on the light-transmitting cover plate 10 may coincide with the second light-transmitting portion 12.
The light rays emitted from the first display unit 21 and the second display unit 22 may be light rays emitted from light emitting units included in the first display unit 21 and the second display unit 22, and may be understood as follows: the first display portion 21 and the second display portion 22 correspond to separate light sources, light emitted from the light source corresponding to the first display portion 21 can be understood as light emitted from the first display portion 21, and light emitted from the light source corresponding to the second display portion 22 can be understood as light emitted from the second display portion 22.
As an alternative embodiment, the first light transmission portion 11 and the second light transmission portion 12 form a second included angle; the first included angle and the second included angle satisfy the following preset relation: sin theta/sin alpha ═ n; wherein θ is the size of the first included angle, α is the size of the second included angle, and n is the refractive index of the light-transmitting cover plate 10.
The area where the optical device 30 is located is usually air, and the refractive index of air can be understood as 1, that is to say: sin θ/sin α ═ n, this formula can be understood as: sin theta/sin alpha is n/1.
In the embodiment of the present application, when the first included angle and the second included angle satisfy the above formula, and when the light emitted from the first display portion 21 irradiates on the first light-transmitting portion 11, the incident angle is θ, and the refraction angle is α, see fig. 3, where B in fig. 3 is used to indicate a light path where the light emitted from the first display portion 21 irradiates on the external environment after being refracted by the first light-transmitting portion 11, as can be seen from fig. 3, the light can be ensured to irradiate on the external environment in a direction perpendicular to the first light-transmitting portion 11, and the display effect of the first display portion 21 is enhanced.
As an alternative embodiment, a third included angle is formed between the first display portion 21 and the second display portion 22, referring to fig. 1, and the first included angle, the second included angle, and the third included angle satisfy the following preset relationships: and theta is alpha + beta, wherein beta is the size of the third included angle.
In the embodiment of the present application, the first included angle, the second included angle, and the third included angle satisfy the following preset relationship: therefore, when the external light is received by the optical device 30 after being refracted by the first light transmission part 11, the external light may finally irradiate the optical device 30 in a direction perpendicular to the light incident surface of the optical device 30, and compared with a mode in which the external light irradiates the optical device 30 in a direction not perpendicular to the light incident surface of the optical device 30, the occurrence of phenomena such as refraction or reflection of the external light on the optical device 30 may be reduced, and further, the loss of the light caused by the phenomena such as refraction or reflection is reduced, that is, the light receiving effect of the optical device 30 is enhanced.
As an alternative embodiment, referring to fig. 2, a magnitude of a first incident angle at which the external light is refracted to the optical device by the first light transmission portion is γ, and a magnitude of the first refraction angle is α, and sin γ/sin α is 1/n.
In this embodiment, it can be further ensured that the external light finally irradiates the optical device 30 in a direction perpendicular to the light incident surface of the optical device 30, so as to further enhance the light receiving effect of the optical device 30.
As an alternative embodiment, referring to fig. 2, the magnitude of the second incident angle at which the external light is refracted from the external environment to the first light transmission portion is phi, and the magnitude of the second refraction angle is alpha-gamma, and sin phi/sin (alpha-gamma) ═ n.
In this embodiment, it can be further ensured that the external light finally irradiates the optical device 30 in a direction perpendicular to the light incident surface of the optical device 30, so as to further enhance the light receiving effect of the optical device 30.
The two embodiments described above may be implemented simultaneously or individually, and are not particularly limited herein.
As an alternative embodiment, the resolution of the first display portion 21 is greater than the resolution of the second display portion 22.
Here, since the light emitted from the first display portion 21 is radiated from the first transparent portion 11 to the external environment by refraction, the light emitted from the second display portion 22 does not need to be radiated to the external environment by refraction, for example: the light emitted from the second display portion 22 can pass through the second transparent portion 22 in a transmissive manner to be irradiated to the external environment, so that if the resolution of the first display portion 21 is the same as that of the second display portion 22, the actual display effect of the first display portion 21 is easily inferior to that of the second display portion 22.
In the embodiment of the application, the resolution of the first display part 21 is controlled to be greater than the resolution of the second display part 22, so that the difference between the actual display effect of the first display part 21 and the actual effect of the second display part 22 is small, the display effect of the whole electronic device is uniform, and the display effect of the whole electronic device is enhanced.
As an alternative embodiment, the electronic apparatus includes a first backlight disposed adjacent to the first display portion 21 and a second backlight disposed adjacent to the second display portion 22.
The light of the first backlight source can pass through the first display portion 21 and irradiate into the external environment through the first light-transmitting portion 11, and the light of the second backlight source can pass through the second display portion 22 and irradiate into the external environment through the second light-transmitting portion 12.
When only one backlight is provided in the electronic device, the light irradiated into the external environment through the first light-transmitting portion 11 may be referred to as a first light, the light irradiated into the external environment through the second light-transmitting portion 12 may be referred to as a second light, and the first light needs to pass through an area where the optical device 30 is located more than the second light, thereby causing the display luminance of the first display portion 21 to be lower than that of the second display portion 22.
In the embodiment of the application, compared with a mode in which only one backlight is provided, the first backlight and the second backlight are provided, and the first backlight is adjacent to the first display portion 21, so that a light supplementing effect is provided for light passing through the second display portion 22, display brightness of the whole electronic device is more balanced, and a display effect of the whole electronic device is enhanced.
It should be noted that the volume and the brightness of the first backlight source may be smaller than those of the second backlight source, so that the use cost may be reduced and the volume of the electronic device may be reduced.
As an optional implementation manner, the electronic device further includes a housing, referring to fig. 1, the display screen 20, the transparent cover plate 10 and the housing enclose to form an accommodating cavity 40, the optical device 30 is located in the accommodating cavity 40, and a refractive index in the accommodating cavity 40 is smaller than a refractive index of the transparent cover plate 10.
The accommodating cavity 40 may be a closed cavity, so that the optical device 30 is disposed in the accommodating cavity 40, and the waterproof and dustproof effects on the optical device 30 can be enhanced.
In the embodiment of the present application, the refractive index in the accommodating cavity 40 is smaller than the refractive index of the light-transmitting cover plate 10, so that the light irradiates to the external environment in the direction perpendicular to the light-transmitting cover plate 10 when passing through the accommodating cavity 40 and the light-transmitting cover plate 10 in sequence, thereby further enhancing the display effect of the electronic device.
It should be noted that the specific structure of the accommodating cavity 40 is not limited herein, and as an optional embodiment, a light-transmitting portion is disposed in the accommodating cavity 40, the optical device 30 is embedded in the light-transmitting portion, and the refractive index of the light-transmitting portion is smaller than that of the light-transmitting cover plate 10.
In the embodiment of the application, because the light-transmitting part can be filled in the accommodating cavity 40, the fixing effect on the optical device 30 can be enhanced while the refraction effect on light is enhanced, and meanwhile, the waterproof and dustproof effect on the optical device 30 can be enhanced.
The specific material of the light-transmitting portion is not limited herein. As an alternative embodiment, the light-transmitting portion is made of a glass material. Therefore, the light-transmitting performance of the light-transmitting part is better, the use cost is lower, and meanwhile, the use cost is lower.
In addition, the light transmission part can be made of traditional polymer light transmission materials or other materials, so that the light transmission performance of the light transmission part is good, and the diversity and flexibility of manufacturing materials of the light transmission part are enhanced.
The light-transmitting portion has a high light-transmitting property, and therefore has a low reflectance with respect to light, that is, reflects a small amount of light.
As another alternative, the accommodating chamber 40 is a vacuum accommodating chamber or an accommodating chamber containing air. Thus, compared with the mode that the light transmission part is arranged in the accommodating cavity 40, the volume of the whole electronic device can be reduced, and meanwhile, the accommodating cavity 40 can be guaranteed to have a good light refraction effect.
In an alternative embodiment, the display 20 is a liquid crystal display or an organic light emitting semiconductor display.
Among them, the Liquid Crystal Display may also be referred to as a Liquid Crystal Display (LCD); the Organic Light-Emitting semiconductor display panel may also be referred to as an Organic Light-Emitting semiconductor display (OLED) panel.
In the embodiment of the present application, the display screen 20 is a liquid crystal display screen or an organic light emitting semiconductor display screen, so that the diversity and flexibility of the display screen 20 are enhanced, and the use scenes of the embodiment of the present application are increased.
As an optional implementation manner, when the display screen 20 is a liquid crystal display screen, the liquid crystal display screen includes a first polarizer, a first substrate, a color filter, a first alignment film, a second substrate, and a second polarizer, which are sequentially stacked, and a liquid crystal is filled between the first alignment film and the second alignment film. In this way, by arranging the first polarizer, the color filter, the first alignment film, the second alignment film and the second polarizer, light can be filtered, and the display effect of the display screen 20 can be enhanced.
The following is illustrated by a specific example:
referring to fig. 3, a third angle between the first display portion 21 and the second display portion 22 may be referred to as β, a second angle formed by the first light transmitting portion 11 and the second light transmitting portion 12 may be referred to as α, a refractive index of the receiving cavity 40 is n1, and a refractive index of the light transmitting cover plate 10 is n2 (which may also be understood as n in the above embodiment).
When the optical device 30 is in the non-operating state, the incident angle of the light emitted from the first display unit 21 is θ, α + β, and the refraction angle of the light-transmitting cover 10 is α, which satisfies sin (α + β)/sin α, n2/n 1. It can be seen that n1 is smaller than n2, so that when the above relationship is satisfied, the light at this time can be ensured to irradiate to the external environment in the direction perpendicular to the transparent cover plate 10, and B in fig. 3 is a schematic propagation path of the light at this time.
Referring to fig. 1 and fig. 2, when the optical device 30 is in an operating state, an incident angle between light in an external environment and the transparent cover 10 may be Φ, an incident angle at a boundary between the transparent cover 10 and the receiving cavity 40 is γ, and a refraction angle of the receiving cavity 40 is α, and then sin γ/sin α is n1/n2, and thus γ is arcsin (n1 sin α/n 2).
It is determined that the refraction angle at the boundary between the accommodating cavity 40 and the first light transmission part 11 should be α - γ, and when the accommodating cavity 40 is an accommodating cavity containing air, and the refractive index of the air is 1, sin Φ/sin (α - γ) ═ n2 is known, and Φ ═ arcsin [ n2 ═ sin (α - γ) ] can be calculated.
Therefore, referring to fig. 4, a range between a first solid line 401 and a second solid line 402 in fig. 4 represents a viewing range of the electronic device in other manners, and a range between a first broken line 403 and a second broken line 404 in fig. 4 represents a viewing range of the electronic device in the embodiment of the present application. The angle is small, and phi is about 16 degrees, which is calculated by taking alpha as 30 degrees, n1 as 1 and n2 as 1.5 as examples. As can be seen, the viewing width of the embodiments of the present application has no effect.
