Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Electronic devices, such as mobile phones or tablet computers, generally have infrared sensors installed to detect the distance between the electronic device and a user. Taking a mobile phone as an example, an infrared sensor is arranged in the upper area of the mobile phone. When a user carries out voice call or related operation, the mobile phone is close to the head, the infrared sensor feeds distance information back to the processor, and the processor executes corresponding instructions, such as closing light of the display screen assembly. In the related art, the infrared sensor disposed on the electronic device needs to be provided with corresponding holes for transmitting and receiving infrared signals, but with the development of the electronic device, the requirements of people on the appearance and the operation experience of the mobile phone are higher and higher. The mobile phone has been developed towards the direction of the full-screen, and the full-screen mobile phone forms an ultra-narrow frame between the casing and the display screen assembly, and because the width of the ultra-narrow frame is too small, the ultra-narrow frame may not have enough space to open a hole, so that the overall strength of the frame is reduced even if the hole is opened, and further the reliability of the electronic equipment is low.

Referring to fig. 1 and 2, an electronic device 100 according to an embodiment of the invention includes the electronic device 100 and a housing 20. The electronic device 100 may be a mobile phone or a tablet computer. The electronic device 100 according to the embodiment of the present invention is described by taking a mobile phone as an example, but it is to be understood that the specific form of the electronic device 100 may be other, and is not limited herein.

Referring to fig. 3, the electronic device 100 includes a display 13, an infrared sensor 16, and a light blocking member 30. The display 13 includes a display area 1311 and a non-display area 1312, and the non-display area 1312 surrounds the display area 1311. The infrared sensor 16 is located below the display 13 and includes an emitter 161 and a receiver 162, the emitter 161 being configured to emit infrared light, for example, the emitter 161 emitting infrared light through the non-display area 1312. The receiver 162 is used for receiving infrared light, for example, the receiver 162 receives infrared light through the display region 1311. The light blocking member 30 is disposed between the emitter 161 and the display region 1311, and the light blocking member 30 is used to block infrared light emitted from the emitter 161 from entering the display region 1311.

It is understood that the display 13 includes an upper surface 131 and a lower surface 132, and that the display 13 is adapted to emit light for display through the upper surface 131. The display 13 is transparent so that infrared light from the emitter 161 is transmitted through the display 13 and, similarly, reflected infrared light is received by the receiver 162 through the display 13.

The transmitter 161 is used for transmitting infrared light, when the transmitted infrared light meets an obstacle in the detection direction, a part of the infrared light is reflected back to be received by the receiver 162, and the processor calculates the time from the transmission of the infrared light to the reflection of the infrared light, so that the distance between the electronic device 100 and the obstacle can be determined and corresponding adjustment can be made. In one example, when the user is answering or making a call, the electronic device 100 is close to the head, the transmitter 161 emits infrared light, the receiver 162 receives the infrared light reflected back by the head, the processor calculates the time from emission to reflection of the infrared light, and sends a corresponding instruction to control the screen to close the background light, and when the electronic device 100 is far away from the head, the processor calculates again according to the data fed back and sends an instruction to re-open the screen background light. Therefore, misoperation of the user is prevented, and the electric quantity of the mobile phone is saved.

Since the emitter 161 has a certain emission angle, even if the emitter 161 is located outside the display area 1311, there is no guarantee that infrared light emitted by the emitter 161 cannot enter the display area 1311. Therefore, the light blocking element 30 blocks the infrared light emitted by the emitter 161 from entering the display region 1311, and prevents the infrared light from adversely affecting the optoelectronic elements in the display region 1311. In one example, the light blocking member 30 is foam. Of course, the light blocking member 30 may be other non-light transmissive materials such as plastic.

In the electronic device 100, the receiver 162 serves as an input element of the electronic device 100, and the receiver 162 can receive an infrared signal and input the signal into the electronic device 100. The display 13 serves as an output element of the electronic device 100, and the display 13 can output display contents to the outside of the display 13 for a user to obtain corresponding information.

The housing 20 is used for accommodating the electronic device 100 to protect the electronic device 100. The casing 20 encloses the electronic device 100 by disposing the electronic device 100 in the casing 20, so as to prevent external factors from directly damaging the internal components of the electronic device 100. The housing 20 may be formed by CNC machining of an aluminum alloy, or may be injection molded using Polycarbonate (PC) or PC + ABS material.

In summary, in the electronic device 100 according to the embodiment of the invention, the display 13 enables the infrared sensor 16 to be disposed below the display 13 to ensure that the electronic device 100 achieves a full-screen effect, and in addition, the orthographic projection of the emitter 161 of the red light sensor 16 on the lower surface 132 of the display 13 is located outside the display area 1311 and the light blocking element 30 blocks infrared light from entering the display area 1311, so that the infrared light emitted by the emitter 161 can be prevented from affecting the operating stability of the TFT of the display area 1311, and the display 13 and the infrared sensor 16 can achieve respective functions without interfering with each other.

Specifically, the electronic device 100 further includes a battery 110 and a main circuit board 120, the battery 110 and the main circuit board 120 are both disposed on the same side of the casing 20, and the battery 110 and the display 13 are disposed on opposite sides of the casing 20. The battery 110 is used for supplying power to the electronic device 100, and the main circuit board 120 is configured to control an operating state of the electronic device 100, for example, the main circuit board 120 controls the display 13 to play video content.

In some embodiments, the display 13 comprises an O L ED display.

Specifically, an Organic light Emitting Diode (Organic L light-Emitting Diode, O L ED) display screen has good light transmittance and can transmit visible light and infrared light.

Referring to fig. 4, in some embodiments, the light blocking member 30 is adhered and fixed at the connection between the display region 1311 and the non-display region 1312. In this way, the fixing manner of the light blocking member 30 is easily achieved, so that the electronic device 100 is easily manufactured. In one example, when the light blocking member 30 is fixed to the lower surface 132 of the display 13, a double-sided adhesive tape may be attached to one surface of the light blocking member 30, and then the light blocking member 30 may be fixedly attached to the joint between the display region 1311 and the non-display region 1312 by the double-sided adhesive tape.

Referring to fig. 3, in some embodiments, the infrared sensor 16 includes a package 163 for packaging the emitter 161 and the receiver 162, and the light blocking member 30 is fixed on the package 163 and located between the emitter 161 and the receiver 162. In this manner, the light blocking member 30 is fixedly installed, so that the infrared sensor 16 and the light blocking member 30 are fitted with the display screen 13 as a whole.

In some embodiments, the light blocking member 30 is a soft material, and the light blocking member 30 abuts the lower surface 132. Thus, the light blocking element 30 has a better light blocking effect, and ensures that the infrared light emitted by the emitter 161 cannot enter the display region 1311. In addition, the matching structure of the infrared sensor 16 and the display screen 13 is more compact.

Referring to fig. 5, in some embodiments, the light blocking member 30 and the package 163 are an integral structure. In this way, the material of the light blocking member 30 is consistent with the material of the package body 163, and the light blocking member 30 can be formed at the same time of manufacturing the infrared sensor 16, so that the number of parts of the electronic device 100 can be saved to improve the assembly efficiency of the electronic device 100.

In some embodiments, the front projection of the receiver 162 on the lower surface 132 is located within the display area 1311, and the receiver 162 is configured to receive infrared light transmitted through the display area 1311. In this manner, the receiver 162 has a sufficient spatial arrangement. Of course, in some embodiments, the orthographic projection of receiver 162 on lower surface 132 may also be located at a position corresponding to non-display region 1312, as shown in fig. 6.

Referring to fig. 3, in some embodiments, the electronic device 100 further includes a touch layer 12 and a cover plate 11. The cover plate 11 is formed on the touch layer 12, the touch layer 12 is disposed on the display 13, the upper surface 131 of the display 13 faces the touch layer 12, and the light transmittance of the touch layer 12 and the cover plate 11 to visible light and the light transmittance of infrared light are both greater than 90%.

Specifically, the touch layer 12 is mainly used for receiving an input signal generated when a user touches the touch layer 12 and transmitting the input signal to the circuit board for data processing, so as to obtain a specific position where the user touches the touch layer 12. The touch layer 12 and the display screen 13 can be attached by adopting an In-Cell or On-Cell attaching technology, so that the weight of the display screen can be effectively reduced, and the overall thickness of the display screen can be reduced. In addition, the cover plate 11 is disposed on the touch layer 12, so that the touch layer 12 and the internal structure thereof can be effectively protected, and the touch layer 12 and the display screen 13 are prevented from being damaged by external force. The light transmittance of the cover plate 11 and the light transmittance of the touch layer 12 to visible light and infrared light are both greater than 90%, which is not only beneficial to the display screen 13 to better display the content effect, but also beneficial to the infrared sensor 16 arranged below the display screen 13 to stably emit and receive infrared light, and ensures the normal operation of the infrared sensor 16.

In some embodiments, the display 13 is used for displaying light through the display area 1311, and the ratio of the area of the display area 1311 to the area of the cover 11 is greater than 90%. For example, the ratio of the area of the display region 1311 to the area of the cover plate 11 is a ratio of 95%, 96%, or the like.

Specifically, by setting the proportion of the display area 1311 and the cover plate 11, after the display screen 13 is attached to the cover plate 11, the display area 1311 can display the content effect in a large size area, so that not only is good user experience improved, but also the screen occupation ratio of the electronic device 100 is effectively increased, and a comprehensive screen effect is achieved. The non-display area 1312 can also be used to shield other components and metal traces underneath the display 13 to maintain the appearance of the product consistent. The non-display area 1312 may be printed with ink to increase the optical density of the display 13, so as to ensure the light-shielding effect and provide a good visual effect.

Referring to fig. 3, in some embodiments, the electronic device 100 further includes a first coating layer 14, the first coating layer 14 is coated on the bottom surface 132 and covers the emitter 161, the first coating layer 14 is used for transmitting infrared light and intercepting visible light, and the emitter 161 is used for transmitting infrared light through the first coating layer 14.

Specifically, the emitter 161 is usually mounted with a gap during the process of assembly, which results in a gap between the emitter 161 and other components, and visible light enters the gap to leak light. Therefore, in the direction in which the emitter 161 and the display 13 are stacked, the orthographic projection area of the first coating layer 14 on the lower surface 132 covers the orthographic projection area of the emitter 161 on the lower surface 132, so that the emitter 161 can be sufficiently shielded by the first coating layer 14 without affecting the normal operation of the emitter 161, and the effect that the emitter 161 is not visible when the electronic device 100 is viewed from the outside is achieved.

The first coating layer 14 transmits infrared light, so that when the transmitter 161 transmits infrared light outwards for detection, the intensity of the infrared light transmitted through the first coating layer 14 is attenuated to a small extent, or the attenuation degree does not affect the detection process, thereby ensuring the normal operation of the transmitter 161. The first coating layer 14 blocks visible light, so that the visible light cannot pass through the first coating layer 16, and the emitter 161 is visually shielded, thereby achieving the effect that the emitter 161 is not visible when the electronic device 100 is viewed from the outside.

In some embodiments, the infrared sensor 16 includes a proximity sensor, the emitter 161 is configured to emit infrared light through the first coating layer 1311 and the non-display area 1312, and the receiver 162 is configured to receive the infrared light reflected by the object to detect a distance of the object from the upper surface 131.

Specifically, in one example, when the user is answering or making a call, the electronic device 100 is close to the head, the emitter 161 emits infrared light, the receiver 162 receives the reflected infrared light, the processor calculates the time from the emission of the infrared light to the reflection of the infrared light, and emits a corresponding instruction to control the screen to close the background light, and when the electronic device 100 is far away from the head, the processor performs calculation again according to the feedback data and emits an instruction to re-open the screen background light. Therefore, misoperation of the user is prevented, and the electric quantity of the mobile phone is saved.

In certain embodiments, the first coating layer 14 comprises an IR ink having a transmittance of greater than 85% for infrared light and a transmittance of less than 6% for visible light, the IR ink being transparent to infrared light at a wavelength of 850nm to 940 nm.

Specifically, since the IR ink has a characteristic of low transmittance to visible light, the emitter 161 disposed under the first coating layer 14 is not observed based on the visual perception of human eyes when the electronic device 100 is viewed from the outside. Meanwhile, the IR printing ink has the characteristic of high light transmittance to infrared light, so that the emitter 161 can stably emit the infrared light, and the normal work of the emitter 161 is ensured.

Referring to fig. 6, in some embodiments, the transmitter 161 and the receiver 162 are separate structures.

In particular, since the transmitter 161 and the receiver 162 are separate structures, a compact arrangement or a dispersed arrangement may be selected when arranging the components, which is not only beneficial for the electronic device 100 to fully allocate the spatial positions of the components and apply the transmitter 161 and the receiver 162 with various shapes, but also beneficial for the transmitter 161 and the receiver 162 to provide possible positions for other components in the electronic device 100.

In one example, the split emitters 161 and receivers 162 are each disposed below a length edge of the non-display area 1312, as shown in fig. 6.

In another example, the split emitters 161 and receivers 162 are each disposed below a corner corresponding position of the non-display area 1312, as shown in fig. 7.

In yet another example, the split emitters 161 and receivers 162 are respectively disposed below both length edges of the non-display area 1312, as shown in fig. 8.

Referring to fig. 9, in some embodiments, the transmitter 161 and the receiver 162 are of unitary construction.

Specifically, the transmitter 161 and the receiver 162 are of an integral structure, so that line connection between split structures can be omitted, the reduction of line process flow is facilitated, the production efficiency of products is improved, and the production cost is reduced.

In the infrared sensor 16, as in the example of fig. 9, the transmitter 161 is located at a position corresponding to the non-display region 1312, and the receiver 162 is located at a position corresponding to the display region 1311.

In the example of fig. 10, the transmitter 161 and the receiver 162 of the entire structure are each disposed at a position corresponding to the width edge of the non-display region 1312.

Referring to fig. 3 again, in some embodiments, the electronic device 100 further includes a second coating layer 15 coated on the bottom surface 132 and covering the receiver 162, wherein the second coating layer 15 is used for transmitting infrared light and intercepting visible light, and the receiver 162 is used for receiving infrared light through the display region 1311 and the second coating layer 15.

Specifically, the receiver 162 is usually mounted with a gap during the process of assembly, which results in a gap between the receiver 162 and other components, so that visible light enters from the gap and light leakage occurs. Therefore, in the direction in which the receiver 162 and the display 13 are stacked, the orthographic projection area of the second coating layer 15 on the lower surface 132 covers the orthographic projection area of the receiver 162 on the lower surface 132, so that the receiver 162 can be sufficiently shielded by the second coating layer 15 without affecting the normal operation of the receiver 162, and the effect that the receiver 162 is not visible when the electronic device 100 is viewed from the outside is achieved.

The second coating layer 15 may also be an IR ink, which has a characteristic of low transmittance of visible light, so that the receiver 162 disposed under the second coating layer 15 is not perceived by the human eye when the electronic device 100 is viewed from the outside. Meanwhile, since the IR ink has a characteristic of high transmittance to infrared light, the receiver 162 can stably receive infrared light, and normal operation of the receiver 162 is ensured.

In some embodiments, electronic device 100 further includes a buffer layer 17 covering lower surface 132 and avoiding infrared sensor 16.

Specifically, the buffer layer 17 is used to buffer impact force and prevent shock so as to protect the touch layer 12, the display screen 13 and the internal structure thereof, and prevent the display screen 13 from being damaged due to external impact. Cushioning layer 17 may be made of foam or rubber or other soft material. Of course, these cushioning materials are merely exemplary and embodiments of the present invention are not limited in this respect. The purpose of avoiding the infrared sensor 16 during the process of providing the buffer layer 17 is to prevent the buffer layer 17 from blocking the signal received by the infrared sensor 16, so that the infrared sensor 16 is not affected during the process of receiving infrared light.

In some embodiments, electronic device 100 further includes a metal sheet 18 covering buffer layer 17 and avoiding infrared sensor 16.

Specifically, the metal sheet 18 is used for shielding electromagnetic interference and grounding, and has a function of diffusing temperature rise. The metal sheet 18 may be cut out of a metal material such as copper foil or aluminum foil. Of course, these metal materials are merely exemplary and embodiments of the present invention are not limited thereto. In addition, avoiding the infrared sensor 16 during the process of disposing the metal sheet 18 is to prevent the metal sheet 18 from blocking the signal received by the infrared sensor 16 so as not to affect the infrared sensor 16 during the process of receiving infrared light.

Referring to fig. 11 and 12, in some embodiments, the electronic device 100 includes a light sensor 40 and a light guide element 50, the light sensor 40 is disposed below the display region 1311, the light guide element 50 is disposed below the display 13, and the light guide element 50 is used for guiding light passing through the non-display region 1312 to the light sensor 40.

In this way, the light sensor 40 is disposed below the display area 1311 to ensure that the electronic device 100 achieves the full-screen effect, and in addition, the light guide element 50 guides light to the light sensor 40 through the non-display area 1312, so that the light sensor 40 can accurately sense the ambient light intensity around the electronic device 100, and the light emitted from the display area 1311 is prevented from causing adverse effects on the light sensor 40.

If the light sensor 40 is disposed under the display region 1311 and the ambient light intensity is detected through the display region 1311, at this time, a portion of the light emitted from the organic light emitting layer of the display region 1311 is reflected to the lower side of the display region 1311, so that the light sensor 40 detects the intensity of the ambient light and the intensity of the light generated by the display region 1311 at the same time, and the accuracy of detecting the intensity of the ambient light by the light sensor 40 is low.

In particular, light guiding element 50 may be made of a transparent light guiding material, for example, the material of light guiding element 50 is plastic or glass. The number of the light guide elements 50 may be specifically set according to requirements, for example, the number of the light guide elements 50 is 1, 2, or the like. The light guide element 50 includes a light input end 51 and a light output end 52, the light input end 51 faces the non-display area 1312, and the light output end 52 faces the light sensor 40, so that the light guide element 50 guides the visible light transmitted through the non-display area 1312 to the light sensor 40.

When the light sensor 40 receives different light intensities, currents with different intensities are generated, so that the ambient light brightness is sensed. For example, when the user is under the sun, the ambient light is strong, the light sensor 4016 feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to enhance the brightness of the display screen to adapt to the light intensity of the current environment, so that the content of the screen viewed by the user is clearer. When the user is in a dark environment, the ambient light is weak, the light sensor 40 feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to reduce the brightness of the display screen to adapt to the light intensity of the current environment, so that the user does not feel dazzling when watching the screen content, and the optimal visual effect is provided for the user. Therefore, the method is not only beneficial to protecting the eyesight of the user, but also saves the electric quantity of the mobile phone and can further achieve the effect of prolonging the service life of the battery. Further, the light sensor 40 may also be used to adjust the white balance when the user is using the photographing function.

In some embodiments, the light guide element 50 includes a vertical portion 53 and a horizontal portion 54 connected to the vertical portion 53, the vertical portion 53 includes a facing non-display region 1312, and the horizontal portion 54 is bent toward the light sensor 40 at a bottom end of the vertical portion 53.

The light guide element 50 is substantially L-shaped, so that the light sensor 40 can be more easily disposed under the display region 1311. of course, in some embodiments, the light guide element 50 may have other shapes such as an arc shape, so long as the light transmitted through the non-display region 1312 is guided to the light sensor 40.

In some embodiments, the light incident direction of the light guide element 50 is perpendicular to the non-display region 1312, and/or the light emergent direction of the light guide element 50 is perpendicular to the light sensor 40.

That is, in some embodiments, the light incident direction of the light guide element 50 is perpendicular to the non-display region 1312. Alternatively, in some embodiments, the light-emitting direction of the light guide element 50 is perpendicular to the light sensor 40. Alternatively, in some embodiments, the light incident direction of the light guide element 50 is perpendicular to the non-display area 1312, and the light emergent direction of the light guide element 50 is perpendicular to the light sensor 40.

Thus, most of the visible light transmitted through the non-display area 1312 reaches the light sensor 40 after passing through the light guide element 50, so that the collimation rate of the light sensor 40 for detecting the ambient light is high.

In some embodiments, the outer peripheral surface of light directing element 50 is coated with a black coating. In this way, it is possible to prevent loss of visible light due to emission from the outer peripheral surface of the light guide element 50, and to reduce the accuracy of the optical sensor 40 in detecting ambient light.

In some embodiments, the light sensing surface of the light sensor 40 is opposite to the display region 1311. Thus, the light sensor 40 is prevented from being adversely affected by the visible light emitted from the display region 1311.

It should be noted that the light sensing surface of the light sensor 40 is opposite to the display area 1311, that is, an included angle between the light sensing surface of the light sensor 40 and the lower surface of the display area 1311 is greater than or equal to 90 degrees and less than or equal to 180 degrees, so as to prevent light generated by the display area 1311 from transmitting the light sensing surface of the light sensor 40.

In some embodiments, light sensor 40 comprises an ambient light sensor for sensing ambient light, and a processor for adjusting the brightness of the display screen based on the intensity of light sensed by the ambient light sensor.

Specifically, when the user is under the sun, the ambient light is strong, the ambient light receiver feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to enhance the brightness of the display screen to adapt to the light intensity of the current environment, so that the content of the screen viewed by the user is clearer. When the user is in a dark environment, the ambient light is weak, the ambient light receiver feeds back the light intensity of the environment to the processor, and the processor executes corresponding instructions to reduce the brightness of the display screen to adapt to the light intensity of the current environment, so that the user does not feel dazzling when watching the screen content, and the optimal visual effect is provided for the user. Therefore, the method is not only beneficial to protecting the eyesight of the user, but also saves the electric quantity of the mobile phone and can further achieve the effect of prolonging the service life of the battery.
