Electronic devices, such as mobile phones or tablets, generally detect the distance between the electronic device and the user by installing an infrared sensor. Taking a mobile phone as an example, an infrared sensor is provided in an upper area of the mobile phone. When the user makes a voice call or related operation, the mobile phone approaches the head, and the infrared sensor feeds the distance information to the processor, and the processor executes corresponding instructions, such as turning off the light of the display component. In the related art, setting an infrared sensor on an electronic device requires opening a corresponding hole in the casing for transmitting and receiving infrared light signals, but with the development of electronic devices, people are increasingly demanding the appearance and operation experience of the mobile phone. The higher. The mobile phone has been developed in the direction of a full screen, and the full screen mobile phone forms an ultra-narrow bezel between the casing and the display assembly. Since the width of the ultra-narrow bezel is too small, there may not be enough space to open the hole, even if the opening will result in The overall strength of the frame is reduced, which in turn makes the reliability of the electronic device low.

Referring to FIG. 1, the electronic device 100 of the embodiment of the present invention may be a mobile phone or a tablet computer or the like. The electronic device 100 of the embodiment of the present invention is described by taking a mobile phone as an example. Of course, the specific form of the electronic device 100 may be other, and is not limited herein.

Referring to FIGS. 2 and 3 , the electronic device 100 includes a transparent display 13 , an infrared sensor 16 , and a housing 20 .

The transparent display screen 13 includes an upper surface 131 and a lower surface 132. The upper surface 131 is disposed opposite to the lower surface 132. The lower surface 132 includes a display area 1311 and a frame area 1312. The frame area 1312 surrounds the display area 1311. The transparent display screen 13 is used for illuminating display through the upper surface 131. The infrared sensor 16 includes a transmitter 1611 for emitting infrared light through the bezel area 1312 and a receiver 1612 for receiving infrared light through the display area 1311.

The emitter 1611 is configured to emit infrared light. When the emitted infrared light encounters an obstacle in the detection direction, a part of the infrared light is reflected and received by the receiver 1612, and the time when the infrared light is emitted from the reflection to the reflection is calculated by the processor. The distance between the electronic device 100 and the obstacle can be determined and adjusted accordingly. When the user answers or makes a call, the electronic device 100 approaches the head, the transmitter 1611 emits infrared light, and the receiver 1612 receives the infrared light reflected by the head, and the processor calculates the time when the infrared light is emitted from the reflection to the reflection. The corresponding command is sent to control the screen to turn off the backlight. When the electronic device 100 is away from the head, the processor again performs calculation based on the feedback data and issues an instruction to reopen the backlight of the screen. In this way, not only the user's misoperation is prevented, but also the power of the mobile phone is saved.

The housing 20 is used to house components and components for protection. By arranging the housing 20 to enclose the components and components, external factors are prevented from causing direct damage to these components. The housing 20 can be formed by machining an aluminum alloy by a CNC machine tool, or can be injection molded from a polycarbonate (PC) or a PC+ABS material.

In summary, the electronic device 100 of the embodiment of the present invention can use the transparent display 13 to set the infrared sensor 16 under the transparent display 13 in the case of a full screen, thereby avoiding the traditional opening operation and ensuring the electronic The reliability of the overall strength of the bezel area 1312 of the device 100 further increases the screen ratio of the electronic device. The emitter 1611 of the red light sensor 16 is disposed in the bezel area 1312 while avoiding the infrared light emitted by the emitter 1611 from affecting the operational stability of the TFT of the display area 1311.

In some embodiments, the light transmissive display 13 includes an OLED display.

Specifically, an Organic Light-Emitting Diode (OLED) display screen has good light transmittance and is capable of transmitting visible light and infrared light. Therefore, the OLED display does not affect the infrared sensor to emit and receive infrared light in the case of exhibiting the effect of the content. The transparent display 13 can also adopt a Micro LED display, which also has good light transmittance for visible light and infrared light. Of course, these displays are merely exemplary and embodiments of the invention are not limited thereto.

Referring to FIG. 4 , in some embodiments, the electronic device 100 further includes a transparent touch panel 12 and a transparent cover 11 . The transparent cover 11 is formed on the transparent touch panel 12 , and the transparent touch panel 12 is disposed on the transparent display 13 . The upper surface 131 of the transparent display 13 faces the transparent touch panel 12 . The light transmittance of the control panel 12 and the transparent cover plate 11 for visible light and the transmittance of infrared light are both greater than 90%.

Specifically, the transparent touch panel 12 is mainly used to receive an input signal generated by the user when the transparent touch panel 12 is touched and transmitted to the circuit board for data processing, thereby obtaining a specific touch of the transparent touch panel 12 by the user. position. The In-Cell or On-Cell bonding technology can be used to attach the transparent touch panel 12 to the transparent display panel 13, which can effectively reduce the weight of the display and reduce the overall thickness of the display. In addition, the transparent cover 11 is disposed on the transparent touch panel 12, which can effectively protect the transparent touch panel 12 and its internal structure, and avoid external force on the transparent touch panel 12 and the transparent display. 13 damage. The transmittances of the transparent cover 11 and the transparent touch panel 12 for visible light and infrared light are both greater than 90%, which not only facilitates the transparent display 13 to better display the content effect, but also facilitates setting in the transparent display. The infrared sensor 16 under the screen 13 stably emits and receives infrared light, which ensures the normal operation of the infrared sensor 16.

Referring to FIG. 3, in some embodiments, the transparent display screen 13 is used to illuminate the display area 1311, and the ratio of the area of the display area 1311 to the transparent cover 11 is greater than 90%.

Specifically, after the transparent display panel 13 is pasted through the transparent cover 11 by setting the ratio of the display area 1311 and the transparent cover 11, the display area 1311 can display the content effect in a larger size area, which is not only improved. A good user experience is also effective, and the screen ratio of the electronic device 100 is also effectively increased. The bezel area 1312 can also be used to block other components and metal lines under the light transmissive display 13 to maintain a consistent appearance. The frame area 1312 can enhance the optical density of the transparent display 13 by printing ink, and also provides a good visual effect while ensuring the shading effect.

Referring to FIG. 5 , in some embodiments, the electronic device 100 further includes a first coating layer 14 , and the first coating layer 14 is coated on the lower surface 132 and covers the emitter 1611 .

Specifically, the installation of the emitter 1611 during process assembly generally requires the assembly gap to be reserved, resulting in a gap between the emitter 1611 and other components, allowing visible light to enter from the gap, causing light leakage. Therefore, in the direction in which the emitter 1611 and the transmissive display 13 are stacked, the area of the orthographic projection of the first coating layer 14 at the lower surface 132 covers the area of the orthographic projection of the emitter 1611 at the lower surface 132, without affecting the emitter. In the case of normal operation of the 1611, the first coating layer 14 is sufficiently shielded from the emitter 1611, so that when the electronic device 100 is viewed from the outside, the effect that the emitter 1611 is invisible is achieved.

In some embodiments, the first coating layer 14 is used to transmit infrared light and intercept visible light, and the emitter 1611 is configured to emit infrared light through the first coating layer 14 and the bezel region 1312.

Specifically, the first coating layer 14 transmits infrared light, so that when the emitter 1611 detects the outward emitting infrared light, the intensity of the infrared light passing through the first coating layer 14 is attenuated less, or attenuated. The degree does not affect the detection process, thus ensuring the normal operation of the transmitter 1611. The first coating layer 14 intercepts visible light so that visible light cannot pass through the first coating layer 16 to visually block the emitter 1611, so that when the electronic device 100 is viewed from the outside, the effect of the emitter 1611 being invisible is achieved.

In some embodiments, the infrared sensor 16 includes a proximity sensor that includes a signal transmitter 1 and a signal receiver for emitting infrared light through the first coating layer 1311 and the bezel region 1312, the signal receiver being used for Infrared light reflected by the object is received to detect the distance of the object from the electronic device 100.

Specifically, when the user answers or makes a call, the electronic device 100 approaches the head, the signal transmitter emits infrared light, the signal receiver receives the reflected infrared light, and the processor calculates the time when the infrared light is emitted from the reflection to the reflection. The corresponding command control screen turns off the backlight. When the electronic device 100 is away from the head, the processor again performs calculation based on the feedback data and issues an instruction to reopen the screen backlight. In this way, not only the user's misoperation is prevented, but also the power of the mobile phone is saved.

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

Specifically, since the IR ink has a characteristic of low light transmittance to visible light, when the electronic device 100 is viewed from the outside, the emitter 1611 disposed under the first coating layer 14 is not visually observed based on the human eye. At the same time, since the IR ink has the characteristics of high transmittance to infrared light, the emitter 1611 can stably emit infrared light, and the normal operation of the emitter 1611 is ensured.

Referring to Figures 6-9C, in some embodiments, the transmitter 1611 and the receiver 1612 are of a split configuration.

Specifically, since the transmitter 1611 and the receiver 1612 are in a separate structure, a compact arrangement can be selected in the arrangement position, or a distributed arrangement can be selected, and the receiver 1612 can be flexibly set in an area such as a low frequency display. A location that has little effect on the display pixels. As such, it is advantageous not only for the electronic device 100 to adequately allocate the spatial position of each component and to apply the various shapes of the transmitter 1611 and the receiver 1612, but also to facilitate the transmitter 1611 and the receiver 1612 to provide other components in the electronic device 100. The position and the effect on the display pixels of the electronic device 100 is reduced. When the transmitter 1611 and the receiver 1612 are arranged in a distributed manner, a transmitter 1611 may be disposed in the bezel area 1312, and a receiver 1612 may be disposed in the display area 1311. It is also possible to provide a transmitter 1611 in the bezel area 1312 and a plurality of receivers 1612 in the display area 1311. A transmitter 1611 may be disposed on each side of the frame area 1312, and a receiver 1612 is disposed on each side of the display area 1311.

Referring to FIG. 5, in some embodiments, the transmitter 1611 and the receiver 1612 are of unitary construction.

Specifically, the transmitter 1611 and the receiver 1612 are integrated structures, and the integrated structure makes the overall structure of the component compact, so that the layout of the components under the display screen is reasonable, the circuit process flow and the wiring space are reduced, the production efficiency of the product is improved, the production cost is reduced, and the component layout is reduced. Regularization is convenient for maintenance and maintenance.

In some examples, the unitary structure may also include an ambient light sensor to further increase the integration of the components.

The light is intercepted and the receiver 1612 is configured to receive infrared light through the display area 1311 and the second coating layer 15.

Specifically, the installation of the receiver 1612 during process assembly generally requires the assembly gap to be reserved, resulting in a gap between the receiver 1612 and other components, allowing visible light to enter from the gap, causing light leakage. Therefore, in the direction in which the receiver 1612 and the transmissive display 13 are stacked, the area of the orthographic projection of the second coating layer 15 at the lower surface 132 covers the area of the orthographic projection of the receiver 1612 at the lower surface 132, without affecting the receiver. When the 1612 is operating normally, the second coating layer 15 is sufficiently shielded from the receiver 1612, so that when the electronic device 100 is viewed from the outside, the effect of the receiver 1612 being invisible is achieved. The second coating layer 15 may also employ an IR ink. Since the IR ink has a characteristic of low transmittance to visible light, when the electronic device 100 is viewed from the outside, the human eye-based vision cannot be perceived to be disposed on the second coating layer. Receiver 1612 under 15. At the same time, since the IR ink has the characteristics of high transmittance to infrared light, the receiver 1612 can stably receive infrared light, and the normal operation of the receiver 1612 is ensured.
