Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the scope of protection of this application.

It is to be understood that data so used are interchangeable under appropriate circumstances so that embodiments of the present application can be practiced in sequences other than those illustrated or described herein. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates a context. The object is an "or" relationship.

The electronic device in the embodiment of the present application may be a mobile electronic device or a non-mobile electronic device. For example, the mobile electronic device may be a mobile phone, a tablet computer, a notebook computer, a handheld computer, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a personal digital assistant (personal digital assistant). assistant, PDA), etc., and the non-mobile electronic device can be a personal computer (PC), a television (TV), a teller machine or a self-service machine, etc., which are not specifically limited in the embodiments of this application.

The electronic device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios.

As shown in Figure 1, one of the schematic structural diagrams of an electronic device provided by an embodiment of the present application; as shown in Figure 1, the electronic device 1000 may include: an optical device 100 and a light guide channel 200; The channels 200 are arranged relatively; the first viewing angle of the optical device 100 in the first direction is greater than the second viewing angle of the optical device 100 in the second direction; wherein, the cumulative tolerance of the devices in the electronic device 1000 in the first direction has a greater impact on the optical device The optical impact of 100 is greater than the optical impact of the cumulative tolerance of the components in the electronic device 1000 in the second direction on the optical device 100 .

It can be understood that in the embodiments of the present application, the cumulative tolerance of the components in the electronic device in one direction may be the sum of the process tolerance and assembly tolerance of these components. Wherein, the devices in the electronic equipment may include the above-mentioned optical devices.

Optionally, in the embodiment of the present application, the first direction is perpendicular to the second direction, and both the first direction and the second direction are perpendicular to the optical center of the optical device.

Specifically, as shown in Figure 1, the first direction can be the direction shown by the Y axis in the three-dimensional rectangular coordinate system, the second direction can be the direction shown by the X axis in the three-dimensional rectangular coordinate system, and the optical center of the optical device is the direction shown by the Z axis in the three-dimensional rectangular coordinate system.

As shown in Figure 1, straight line l1 and straight line l2 are straight lines in the Y plane, straight line l3 and straight line l4 are straight lines in the X plane, and the intersection of the Y plane and the X plane is the optical center of the optical device. The first viewing angle can is the angle between the straight line l1 and the straight line l2; the second visual angle can be the angle between the straight line l3 and the straight line l4.

In the embodiment of the present application, the center of the first visual angle, the center of the second visual angle, and the optical center of the optical device coincide with each other.

It can be understood that the total viewing angle of the optical device in all directions perpendicular to the optical center of the optical device can be used to indicate the radiation angle range of the optical device (the radiation angle range shown as 104 in Figure 1), which is also Can be called the transmit or receive angle range.

Among them, the closer to the center of the radiation angle range of the optical device, the greater the radiation intensity of the optical device; the further away from the center of the radiation angle range of the optical device, the smaller the radiation intensity of the optical device. That is, the radiation intensity of the optical device is maximum at the center of the radiation angle range and minimum at the edge of the radiation angle range. In other words, the radiation intensity/radiation density of the optic gradually decreases from the center of the optic's viewing angle (optical center) to the edge of the viewing angle.

In actual implementation, the thickness can be used to identify the radiation capability of the optical device (the greater the radiation intensity, the stronger the radiation capability).

It can be understood that the radiation intensity of an optical device includes light energy receiving intensity and light energy emitting intensity.

When the radiation angle range of an optical device in an electronic device is small in one direction, the tolerance of the electronic device in that direction may cause the relative radiation intensity (also called effective radiation intensity) of the optical device in that direction to be smaller, This results in poor optical performance of the optical device.

For example, when micro-slit technology is used to set up optical devices of an electronic device, due to the size of the silk screen area and the light guide channel (light guide column) on the display screen of the electronic device in the first direction (for example, the Y direction of the electronic device) are developing in an increasingly narrow direction. Therefore, the cumulative tolerance of the devices in the electronic device in the first direction may cause the optical center of the optical device in the related art to be skewed relative to the optical path center of the light guide device or the silk screen area. The center is shifted, resulting in a reduction in the ability of the optical device in the related art to receive/emit optical light energy in the first direction, which may in turn lead to a significant reduction in the optical performance of the optical device in the related art.

Since the optical device in the embodiment of the present application increases the viewing angle in the first direction, even if the optical center of the optical device deviates to a certain extent relative to the center of the light path of the light guide path, for example, the distance between the optical center of the optical device and the light guide path The offset angle is α, which can also ensure that the radiation angle range of the optical device maintains a large overlap range with the light guide path, so that the optical device can emit or receive more light energy through the light guide path, so that the optical device can The relative radiation intensity/density remains unchanged or changes slightly in the first direction, thereby improving the optical performance of the optical device.

Optionally, in the embodiment of the present application, the above-mentioned optical device may be any one of the following: a color temperature sensor, an infrared emitter, an infrared receiver, or a photosensitive sensor. In actual implementation, the above-mentioned optical device can also be any other device used to receive or emit light energy, and the details can be determined according to actual use requirements.

Optionally, in the embodiment of the present application, as shown in FIG. 1 , the above-mentioned optical device 100 may be disposed on the circuit board 200 .

In actual implementation, other optical devices can also be installed on the circuit board. For example, combined with Figure 1, as shown in Figure 2, false Assume that the above-mentioned optical device 100 is an infrared transmitter, and an infrared receiver 500 can also be provided on the circuit board 200. The receiving angle range of the infrared receiver is 501.

Optionally, in the embodiment of the present application, when the target offset angle is within the preset angle range, the relative radiation intensity of the optical device is greater than or equal to the preset radiation intensity. The target offset angle is: the offset angle in the first direction between the center of the first viewing angle and the center of the optical path of the light guide channel.

It should be noted that in the embodiments of the present application, the relative radiation intensity of the optical device can be used to indicate the optical performance of the optical device. Among them, the greater the relative radiation intensity of the optical device, the better the optical performance of the optical device; the smaller the relative radiation intensity of the optical device, the worse the optical performance of the optical device.

Further optionally, in the embodiment of the present application, when the target offset angle is within the preset angle range, the relative radiation intensity of the optical device remains basically consistent, thereby ensuring the effective signal amplitude and reducing the tolerance in the first direction. Effect on the performance of optical devices.

In this way, when the offset angle between the center of the viewing angle of the optical device in the first direction and the center of the optical path of the light guide passage in the first direction is within the preset angle range, the relative radiation intensity of the optical device is greater than or equal to the preset angle. Assume the radiation intensity, therefore, even if the electronic device has a large tolerance in the first direction, the optical performance of the optical device will not be affected or the effect will be small.

The above optical device will be described in detail below in combination with two possible implementations (ie, the first possible implementation and the second possible implementation described below).

The first possible implementation

Optionally, in the embodiment of the present application, as shown in FIG. 3 in conjunction with FIG. 1 , the above-mentioned optical device includes: a base 102 and a body 103 . The base 102 is provided with a reflection groove 1021 with an elliptical cross-section, and the body 103 is provided in the central area of the reflection groove 1021. Wherein, the above-mentioned first direction (for example, the direction indicated by the Y-axis) is parallel to the direction corresponding to the long axis of the ellipse, and the second direction is parallel to the direction corresponding to the short axis of the ellipse.

It can be understood that in the embodiment of the present application, the reflection groove with an elliptical cross-section can make the radiation angle range of the optical device become elliptical. In this way, even if the optical center of the optical device is shifted to a certain extent in the first direction relative to the optical path center of the light guide device, the optical device can still emit or receive more light energy through the light guide device, that is, the relative alignment of the optical device can be ensured. The attenuation of radiation intensity is small. Therefore, the sensitivity of the optical device to the tolerance in the first direction can be reduced to improve the optical performance of the optical device.

Optionally, in the embodiment of the present application, the optical devices are different and the bodies are also different. For example, if the optical device is an infrared transmitter, the main body is an infrared emitting lamp; if the optical device is an infrared receiver, the main body is an infrared receiving chip.

In the embodiment of the present application, from the perspective of components, by changing the shape and size of the reflection groove of the optical device, the viewing angle of the optical device in the first direction can be changed, so that the radiation angle of the optical device is elliptical, thereby ensuring that in the first direction The attenuation of the emitted or received light energy near 0° in one direction is smaller, thereby reducing the impact of the tolerance in the first direction on the optical performance of the optical device.

For example, assuming that the above optical device is an infrared emitter, then: as shown in Figure 4, when the offset angle is within the range of ±30°, compared with an infrared emitter with a circular reflection groove, the infrared emitter has an elliptical shape. The attenuation of the relative radiation intensity of the infrared emitter of the reflective groove is smaller than the attenuation of the relative radiation intensity.

It can be understood that the above offset angle is the offset angle of the optical center of the infrared emitter relative to the optical path center of the light guide device, and the offset angle can be used to represent the cumulative tolerance of the components in the electronic device in the first direction.

The reflective grooves in the embodiments of the present application can effectively change the radiation intensity curve of the optical device. It can be seen that the radiation intensity difference within a small offset angle is small, thereby reducing the impact of the tolerance in the first direction on the optical performance of the optical device.

Optionally, in the embodiment of the present application, a reflective film layer is provided on the inner surface of the above-mentioned reflective groove. The reflectivity of the reflective film layer is greater than or equal to the first preset reflectivity, ensuring that the light energy emission direction is centered and avoiding horizontal Excessive light energy in the direction of the body leads to excessive noise in the system design.

Optionally, in the embodiment of the present application, the above-mentioned reflective film layer may be an anti-reflection film, an aluminum paint film layer, or any other possible reflective film.

The following takes the optical device as an infrared emitter as an example to describe the optical device in the embodiment of the present application.

For example, when the optical device is an infrared emitter, the above-mentioned body is an infrared lamp. When the infrared lamp is powered on, it can radiate infrared light; the golden cup groove (ie, reflection groove) provided on the base can ensure that the infrared light The light emission direction is centered to avoid excessive energy of infrared light horizontal to the direction of the infrared lamp and reduce the infrared noise floor of the infrared transmitter. Among them, the positive electrode of the infrared lamp is connected to the corresponding control chip through a wire (also called a gold wire), and the control chip controls the current flowing through the infrared lamp.

In this way, by designing the cross-section of the reflective groove of the optical device into an elliptical shape and making the long axis of the ellipse parallel to the direction that is greatly affected by the cumulative tolerance of the device in the electronic device, the cumulative tolerance can be reduced light to optics Therefore, it can not only improve the optical performance of optical devices in electronic equipment, but also reduce production cost investment (compared to reducing cumulative tolerances).

The second possible implementation

Optionally, in this embodiment of the present application, as shown in FIG. 5 in conjunction with FIG. 1 , the above-mentioned optical device 100 may be composed of at least two sub-optical devices 201 arranged along a first direction (for example, the direction shown by the Y-axis).

The first viewing angle is determined based on the distance between the at least two sub-optical devices 101 and the viewing angles of the at least two sub-optical devices 101 in the first direction, and the second viewing angle is determined based on the spacing between the at least two sub-optical devices 101 in the second direction. The angle of view is determined.

It can be understood that the interval between at least two sub-optical devices is less than or equal to the preset interval (determined according to actual usage conditions). The larger the distance between the at least two sub-optical devices, the larger the first viewing angle, and the smaller the maximum radiation intensity of the optical device. Among them, the maximum radiation intensity (emitting or receiving density) is a property of the optical device itself and has nothing to do with other devices such as light guide devices.

In the embodiment of the present application, each sub-optical device may be an optical device in the related art.

In the embodiment of the present application, each sub-optical device has the same viewing angle in the first direction and the second direction, that is, the radiation angle range of each optical device is circular.

In the embodiment of the present application, at least two sub-optical devices have the same radiation angle range.

It can be seen that when at least two sub-optical devices are arranged along the first direction, the total viewing angle of the at least two sub-optical devices in the first direction must be greater than the total viewing angle of the at least two sub-optical devices in the second direction, so that The radiation angle range of the at least two sub-optical devices is elliptical, and the first direction is the direction of the long axis of the ellipse. In this way, even if the optical center of the optical device in the embodiment of the present application is shifted in the first direction relative to the optical path center of the light guide device, the effective power of the optical device can remain substantially unchanged.

For example, in conjunction with Figure 5, as shown in Figure 6, assuming that the above-mentioned optical device 100 is an infrared emitter, and at least two sub-optical devices are infrared emitter a and infrared emitter b with a circular radiation angle range, then: when The optical center of the optical device, specifically, the symmetry axis of the two infrared emitters in the first direction is offset relative to the optical path center of the light guide device 400, and the offset angle is α. As shown in Figure 7, curve 1 is the distribution curve of the relative radiation intensity of infrared emitter 1, curve 2 is the distribution curve of the relative radiation intensity of infrared emitter 2, and curve 3 is the total distribution curve of infrared emitter 1 and infrared emitter 2. From the distribution curve of relative radiation intensity, it can be seen that when the offset angle α is in the range of [-25°, +25°] internally, the relative radiation intensities of infrared emitter 1 and infrared emitter 2 remain basically unchanged, that is, the infrared emitter combination (i.e., infrared emitter 1 and infrared emitter 2) can ensure relative radiation within the range of ±25° in the Y direction. The radiation intensity is basically the same, thereby ensuring the effective infrared signal amplitude and reducing the sensitivity of the infrared emitter combination to Y-direction tolerances.

It can be understood that when the optical device in the second possible implementation manner is provided in an electronic device, it can ensure that the relative radiation intensity of the optical devices in multiple electronic devices assembled in batches remains consistent, which facilitates debugging of the optical parameters of the optical device. , improve users’ experience of functions.

For example, when the above-mentioned optical device is an infrared emitter, it can also be ensured that the infrared screen-off distances of different electronic devices equipped with infrared emitters are basically the same.

In this way, in the second possible implementation manner, by arranging multiple optical devices in the related art along the direction that is greatly affected by the tolerance, the impact of tolerance on the optical device composed of these optical devices can be reduced. The combined optical performance can therefore improve the optical performance of optical devices.

Furthermore, since there is no need to improve the structure, production process and processing equipment of the optical device in the related art, production costs can be reduced.

It should be noted that in the embodiment of the present application, the long axis of the elliptical radiation angle range of the above-mentioned optical device is parallel to the first direction of the electronic device (for example, the direction shown by the Y-axis in Figure 8), so that the The tolerance of each device in the first direction has basically no interference with the relative radiation intensity of the optical device, thus ensuring the consistency of the light energy increment in the entire machine assembly.

Optionally, in the embodiment of the present application, as shown in FIG. 9 , the electronic device 1000 may further include: a light guide column 210 disposed in the light guide channel 200 ; the first convex light surface 310 of the light guide column 210 faces the optical device 100 , the first convex light surface 320 of the light guide rod is away from/back to the optical device 100 .

The size of the first convex smooth surface 310 in the first direction is larger than the size of the first convex smooth surface 310 in the second direction.

It can be understood that the convex optical surface in the embodiment of the present application is used to gather light energy.

In the embodiment of the present application, since the first viewing angle of the optical device in the first direction is greater than the second viewing angle of the optical device in the second direction, the size of the first convex optical surface in the first direction is larger than the first convex optical surface. The size in the second direction can increase the incident or exit angle of light energy, thereby ensuring that more light energy in the first direction passes through the light guide column, so that more light energy reaches the optical device or more light energy is emitted by the optical device. Being able to pass through the light guide column can increase the phase of the optical device. to the radiation intensity, thereby potentially reducing the impact of tolerances on the optical performance of the optical device.

Optionally, in the embodiment of the present application, in order to meet the demand for a high screen-to-body ratio, the second convex optical surface is a narrow optical surface, and the size of the second convex optical surface in the first direction is usually smaller than the second convex optical surface. The size of the diconvex smooth surface in the second direction. In this case, if the size of the first convex light surface facing the optical device in the first direction is increased, then: for the optical device used to emit light energy, the first convex light surface can increase the light energy in the first direction. The upward incident angle ensures that more light energy enters the light guide column to increase the probability of light energy emerging from the light guide column, thereby increasing the relative radiation intensity of the optical device; for optical devices used to receive light energy, the first convex light The surface can increase the exit angle of light energy in the first direction, thereby ensuring the exit rate of light energy entering the light guide column, thereby improving the relative radiation intensity of the optical device.

Of course, in actual implementation, the size of the first convex smooth surface in the first direction may also be larger than the size of the first convex smooth surface in the second direction, which is determined based on actual usage requirements and is not limited in the embodiments of this application.

Optionally, in the embodiment of the present application, when a light guide column is provided in the light guide channel, the above target offset angle may specifically be: the center of the first viewing angle and the center of the first convex light surface in the first direction. Offset angle, such as offset angle α in Figure 9.

In the embodiment of the present application, as shown in Figure 9, the target offset angle α can be determined by the distance d1 between the first convex optical surface and the optical device, and the optical center of the optical device and the center of the first convex optical surface are at the The distance d2 in one direction is determined, where tanα=d2/d1. It can be seen that the optical center of the optical device should be aligned with the center of the first convex optical surface as much as possible, that is, reduce d2, and reduce the distance d1 between the optical device and the first convex optical surface to ensure the target The offset angle is within the preset offset range, thereby ensuring the effective light energy emission/incidence rate of the optical device.

Specifically, with reference to FIG. 9 , if the optical device 100 needs to satisfy more than 75% of the effective light energy emission/incidence, the angle α between the optical center of the optical device 100 and the center of the first convex optical surface 1021 is less than or equal to ± 25° (preset offset angle range) is enough (at this time, only the light energy emitted/received once is considered. If the light energy of refraction and multiple reflections is considered, the angle will be greater than 25°). Considering that the distance d1 between the optical device 100 and the first convex light surface 1021 is usually equal to about 0.2 mm, the distance d2 between the optical device 100 and the light guide column 210 (specifically, the first convex light surface) in the first direction It only needs to meet ±0.2*tan25°≈±0.11mm. d2=±0.11mm represents the maximum first-direction tolerance between the optical device and the light guide column that can withstand more than 75% of the light energy emitted/incident. This standard can meet the vast majority of current process requirements.

Optionally, in the embodiment of the present application, other surfaces of the above-mentioned light guide rod except the first convex smooth surface and the second convex smooth surface A reflective film layer is provided to ensure that the light entering the light guide column can be emitted from the convex light surface as much as possible.

Optionally, in this embodiment of the present application, the size of the first convex smooth surface in the first direction is larger than the size of the second convex smooth surface in the first direction. In this way, the incident/exit angle of light energy in the light guide column can be increased, thereby minimizing the impact of the tolerance in the first direction on the optical performance.

Optionally, in this embodiment of the present application, as shown in FIG. 9 , the electronic device may further include a display screen 400 , and the display screen 400 is located on the side of the light guide path facing away from the optical device.

In the electronic device provided by the embodiment of the present application, since the viewing angle of the optical device is larger in the first direction that is greatly affected by the cumulative tolerance of the devices in the electronic device, even if the optical device has a larger angle relative to the light guide in the first direction The shift in the center can also ensure that the optical device can receive enough light energy, or ensure that enough light energy in the light energy emitted by the optical device can enter the light guide path. In this way, the impact of the cumulative tolerance in this direction on the optical performance of the optical device can be reduced, and thereby the optical performance of the optical device can be improved without changing the cumulative tolerance.
