[0047] In order to improve the aesthetics of the display, an atmosphere lamp is usually arranged on the back of the display.
[0048] In the related art, a display includes a display body, a rear shell and a light emitting piece. The rear shell is located at the back of the display body. The rear shell has a through hole which surrounds the light emitting piece. Light emitted by the light emitting piece passes through the through hole and is directed to the back of the rear shell. A user can directly see the light emitted by the light emitting piece at the back of the rear shell, thereby forming an atmosphere lamp of the display.
[0049] However, the light emitting form of the atmosphere lamp of the display in the prior art is relatively single. Usually, only a uniform annular light emitting band can be formed. Therefore, it is necessary to enrich the light emitting form of the atmosphere lamp.
[0050] In view of the above technical problems, the display provided by the embodiments of the present disclosure is as shown in Figure 1 and Figure 2 The display includes a display body 1, a rear shell 2 and a light emitting piece 3. The rear shell 2 is located at the back of the display body 1. The rear shell 2 has a through hole 20 and a reflective surface 2a which is located outside the through hole 20. The reflective surface 2a is inclined relative to an axis A of the through hole 20. The distance between the reflective surface 2a and the axis A gradually increases in a direction away from the display body 1. The through hole 20 surrounds the light emitting piece 3. The light emitting piece 3 is configured to emit a light beam to the reflective surface 2a.
[0051] The display can be a computer display screen. The back of the display body 1 is a side of the display body 1 which faces away from the display screen.
[0052] The technical solution provided by the embodiments of the present disclosure is that the distance between the reflective surface 2a and the axis A gradually increases in the direction away from the display body 1. Therefore, the distance between the reflective surface 2a and the light emitting piece 3 also gradually increases. Since the longer the propagation path of light is, the lower the light intensity is, the light intensity on the reflective surface 2a gradually decreases in the direction away from the display body 1. That is, a light ring with gradually decreasing light intensity from inside to outside is formed on the reflective surface 2a. Therefore, a gradient atmosphere lamp is formed on the reflective surface 2a, thereby enriching the light emitting form of the atmosphere lamp.
[0053] In some examples, as shown in Figures 2-4 The light emitting piece 3 includes a light emitting body 31 and a light guide body 32. The light emitting body 31 is located between the display body 1 and the rear shell 2. The light guide body 32 is located on an exit light path of the light emitting body 31. The light guide body 32 penetrates through the through hole 20. The light guide body 32 has an exit light surface 3a which is parallel to the axis A. The light guide body 32 can change the propagation direction of light. Light emitted by the light emitting body 31 is diffused to the exit light surface 3a through the light guide body 32, and then is directed to the reflective surface 2a. In addition, the light guide body 32 can convert a point light source into a surface light source, so that the light is more uniform.
[0054] The axis A of the light emitting body 31, the light guide body 32 and the through hole 20 coincide. The light emitting body 31 and the light guide body 32 can be circular rings or rectangular rings.
[0055] In some examples, as shown in Figure 4 , the angle between the light-reflecting surface 2a and the light-emitting surface 3a is α, and 45°≤α≤75°. In this way, the light reflected by the light-reflecting surface 2a can form a light-emitting band with a wider width and a higher illumination intensity.
[0056] If α is too large, the angle between the light emitted by the light-emitting surface 3a and the light-reflecting surface 2a is too small, so that the light-reflecting surface 2a is less illuminated by the light-emitting surface 3a, and thus the light ring formed by the light-reflecting surface 2a has a smaller width and a lower illumination intensity. If α is too small, although the light emitted by the light-emitting surface 3a can illuminate the light-reflecting surface more, the area of the light-reflecting surface 2a seen by the user when the user is behind the display is smaller, and the light reflected by the light-reflecting surface 2a is more reflected towards the axis A, so that less light is reflected into the eyes of the user, and thus it is difficult to form an atmosphere lamp behind the display.
[0057] In some examples, as shown in Figure 2 , the light-emitting body 31, the light-guiding body 32, and the light-reflecting surface 2a are all annular. The light-emitting body 31, the light-guiding body 32, and the light-reflecting surface 2a can be circular or rectangular. It can be understood that the shape of the light-reflecting surface 2a is the shape of the atmosphere lamp seen by the user.
[0058] Alternatively, in other examples, the light-emitting body 31, the light-guiding body 32, and the light-reflecting surface 2a can also be in the shape of an arc segment or a straight line. Specifically, the shapes of the light-emitting body 31, the light-guiding body 32, and the light-reflecting surface 2a can be set according to actual needs.
[0059] In some examples, as shown in Figure 2 , Figure 4 , and Figure 5 , the light-emitting body 31 includes a support 311 and a plurality of lamp beads 312, and the plurality of lamp beads 312 are fixed to the support 311. The lamp beads 312 are located between the support 311 and the light-guiding body 32, and the side of the light-guiding body 32 facing the lamp beads 312 has an arc-shaped groove 320, and the concave surface of the arc-shaped groove 320 faces the lamp beads 312. The lamp beads 312 can be light-emitting diodes (LEDs).
[0060] As shown in Figure 6As shown, the light guide 32 in the related art does not have the groove, and the light rays on the main optical axis of the lamp bead 312 are along the radial direction of the light guide 32, so that the light rays on the main optical axis can be perpendicularly incident into the light guide 32. It can be understood that the light rays of other angles cannot be perpendicularly incident into the light guide 32. According to the Fresnel reflection law, when the light rays are incident from one medium into another medium, the smaller the incident angle of the light rays, the smaller the reflectivity of the surface of the other medium. That is, the smaller the incident angle of the light rays, the more light rays can enter the other medium. Therefore, when the light rays outside the main optical axis are incident into the light guide 32, more reflection (such as Figure 6 the dotted arrow shown in the middle) occurs, which results in less light being incident into the light guide 32, so that the light emitted by the light guide 32 is dim.
[0061] As shown, because the side of the light guide 32 in the embodiment of the present disclosure towards the lamp bead 312 has the arc-shaped groove 320, the light rays of various angles emitted by the lamp bead 312 have a small angle with the arc-shaped groove 320, so that as many light rays as possible are incident into the light guide 32, thereby improving the illumination intensity on the light-reflecting surface 2a. Figure 7
[0062] For example, the distance between the lamp bead 312 and the arc-shaped groove 320 is equal. That is, the center of the arc-shaped groove 320 is located on the lamp bead 312. In this way, the light rays of various angles emitted by the lamp bead 312 can be perpendicularly incident into the light guide 32, thereby reducing the reflected light on the surface of the light guide 32.
[0063] In some examples, as shown, the central angle of the arc-shaped groove 320 is β, and 60°≤β≤100°. In this way, as many light rays as possible can be incident into the light guide 32 through the arc-shaped groove 320. Figure 7
[0064] If β is too small, only a small part of the light rays emitted by the lamp bead 312 can be incident into the light guide 32 through the arc-shaped groove 320, and most of the light rays enter the light guide 32 through the region of the light guide 32 without the arc-shaped groove 320, so that the surface of the light guide 32 still reflects a lot of light rays. If β is too large, the overall thickness of the light guide 32 is relatively small, so that the strength of the light guide 32 is relatively low, and the light guide 32 is easily damaged.
[0065] In some examples, as shown in Figure 4 and Figure 8 the arc-shaped groove 320 has a bottom wall 320a and a side wall 320b. The bottom wall 320a is arc-shaped, and the bottom wall 320a is located between the side wall 320b and the display main body 1. In this way, the light rays emitted by the lamp bead 312 can be prevented from leaking, so that as many light rays as possible can be incident into the light guide 32 through the arc-shaped groove 320.
[0066] In some examples, as shown in Figure 8 and Figure 9 the bottom wall 320a of the arc-shaped groove 320 has a plurality of spaced strip-shaped grooves 3201 extending along the axis A of the light guide 32. In this way, the bottom wall 320a of the arc-shaped groove 320 is sawtooth-shaped. When the light rays are incident on the surface of the light guide 32, they are reflected and then enter the interior of the light guide 32, so that the light rays are distributed more uniformly. When the light rays are incident on the reflecting surface 2a, a soft fog effect is produced, reducing the glare of the light rays, and avoiding the appearance of a light spot with a bright middle and a dark periphery on the reflecting surface 2a.
[0067] In some examples, as shown in Figure 9 and Figure 10 the light guide 32 includes a first light guide portion 321 and a second light guide portion 322 arranged along the axis. The first light guide portion 321 has an outer diameter greater than that of the second light guide portion 322, the light emitter 31 surrounds the first light guide portion 321, and the through hole 20 surrounds the second light guide portion 322. The first light guide portion 321 has a light inlet surface 3211 and a first reflecting surface 3212, and the second light guide portion 322 has a second reflecting surface 3221 and a light outlet surface 3a. The light inlet surface 3211, the first reflecting surface 3212, the second reflecting surface 3221, and the light outlet surface 3a are arranged in sequence along the light emission path of the light emitter 31. In this way, the light emitted by the lamp bead 312 can be guided to the reflecting surface 2a in sequence.
[0068] The arc-shaped groove 320 is located on the light inlet surface 3211 of the first light guide portion 321.
[0069] In some examples, as shown in Figure 10 the angle between the first reflecting surface 3212 and the main optical axis B of the light emitter 31 is γ, and the angle between the second reflecting surface 3221 and the first reflecting surface 3212 is δ, and 40°≤γ≤50° and 85°≤δ≤95°.
[0070] The material of the light guide 32 is generally transparent PC (Polycarbonate) or transparent ABS (Acrylonitrile Butadiene Styrene). The refractive index of transparent PC is 1.586, the refractive index of transparent ABS is 1.56, and the refractive index of air is 1.0003. According to the law of refraction, when light rays enter a less dense medium (a medium with a higher refractive index) from a more dense medium (a medium with a lower refractive index), total internal reflection occurs if the angle of incidence is greater than the critical angle.
[0071] Calculations show that the critical angle for PC is approximately arcsin(1.003 / 1.586) ≈ 39.1°, and for ABS it is approximately arcsin(1.003 / 1.56) ≈ 39.9°. Setting 40° ≤ γ ≤ 50° ensures that the incident angle of light on the first reflecting surface 3212 is 40°-50°. Setting 85° ≤ δ ≤ 95° ensures that the incident angle of light on the second reflecting surface 3221 is 45°-55°. This allows for total internal reflection of light within the light guide 32, preventing transmission through the first and second reflecting surfaces 3212. This reduces light scattering loss, enhances light reflection, improves light utilization, and ultimately increases overall luminous brightness.
[0072] For example, γ = 45°, δ = 45°.
[0073] In some examples, such as Figure 3 and Figure 10 As shown, the display also includes a baffle 4. The baffle 4 is located on the side of the rear housing 2 facing away from the display body 1 and opposite the through hole 20. A gap exists between the baffle 4 and the reflective surface 2a, through which the light-emitting element 3 emits a light beam towards the reflective surface 2a. The baffle 4 is used to block the through hole 20 and part of the light guide 32. It is understood that the baffle 4 does not block the reflective surface 2a, or only a small portion of it, allowing the user to see the reflective surface 2a.
[0074] In some examples, such as Figure 1 As shown, the monitor also includes a support base 5. The support base 5 is connected to the baffle 4 and is used to support the monitor, allowing the monitor to be placed on a desktop.
[0075] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
